Installing the Genie Camera
Warning! (Grounding Instructions)
Static electricity can damage electronic components. Please discharge any static electrical charge by touching a
grounded surface, such as the metal computer chassis, before performing any hardware installation.
If you do not feel comfortable performing the installation, please consult a qualified technician.
GigE Network Adapter Guideline
If the computer to be used with the Genie camera does not have a Gigabit network adapter or second built in Gigabit
NIC, a PCI bus Gigabit NIC needs to be installed. Typically under Windows XP the PCI Gigabit NIC is recognized
automatically when Windows boots. An example of a high performance NIC is the Intel PRO/1000 MT adapter.
Review the NIC documentation concerning any special driver required for Windows. Install the PCI bus Gigabit
NIC as described by the NIC manufacture's documentation.
The Genie camera has been tested with a variety of Gigabit network adapters, both built into the system
motherboard and as third party PCI adapters.
Supported Network Configurations
The Genie obtains an IP address using the Link Local Address (LLA) or DHCP, by default. If required, a persistent
The LLA method automatically assigns the Genie with a randomly chosen address on the 169.254.xxx.xxx subnet.
After an address is chosen, the link-local process sends an ARP query with that IP onto the network to see if it is
already in use. If there is no response, the IP is assigned to the device, otherwise another IP is selected, and the ARP
is repeated. Note that LLA is unable to forward packets across routers.
Alternatively, if a DHCP server is present on the network, the Genie is going to issue a DHCP request asking for an
IP address. The DHCP server will then provide the Genie an IP address.
Using Genie with Ethernet Switches
Examples where a Gigabit Ethernet switch would be used are:
•
Multiple Genie cameras are controlled by one computer and a single NIC (running multiple instances of
CamExpert as an example of the control program).
•
Multiple Genie cameras are individually controlled by multiple computers, all located on the same subnet.
In these cases the Ethernet switch is a transparent device. The device discovery process finds all Genie cameras, and
presents them as ready to be controlled by an application such as CamExpert.

Using Genie with a VLAN Ethernet Switch
An Ethernet switch supporting VLAN (Virtual Local Area Network) allows multiple isolated subnets to exist on the
same switch.
Within each VLAN group, the Genie camera and controlling computer will behave identically as if connected to a
simple Ethernet switch. But each VLAN group is isolated from each other, Therefore a Genie in one VLAN group
is never seen by a computer on a different VLAN group.
VLAN Ethernet Switches support configuration as Port-based or TAG VLAN groups. Port-based groups are
typically easier to configure. Review your Ethernet switch manual for information on its factory default VLAN
settings and configuration method.
Installation Overview & Preparations
The Genie camera installation generally follows the sequence described below. Detailed installation instructions
follow this overview.
Network and Computer Overview
•
Genie needs to connect to a computer with a GigE network adapter, either built in on the computer
motherboard or installed as a third party PCI adapter.
•
Laptop computers with built in GigE network adapters may still not be able to stream full frame rates from
Genie, especially when on battery power. Thorough testing is required with any laptop computer to determine
•
•
Genie also can connect through a Gigabit Ethernet switch. When using VLAN groups, the Genie and
controlling computer must be in the same group (see "Using Genie with a VLAN Ethernet Switch" on page 18).
If Genie is to be used in a Sapera development environment, Sapera LT needs to be installed, either before or
after the Genie software package. If Genie will be used in a GenICam™ environment, Sapera or Sapera runtime
is not required and you need to follow the installation instructions of the third party GenICam compliant
package.
•
•
•
Install the Genie Framework software package if not using a third party GenICam compliant package. Also
install Sapera Run-time with CamExpert to control the Genie.
The Windows Firewall exceptions feature is automatically configured to allow the Sapera GigE Server to pass
through the firewall.
Computers with VPN software (virtual private network) may need to have the VPN driver disabled in the NIC
properties. This would be required only on the NIC used with the Genie. Testing by the user is required.

Connect the Genie Camera
Connect a power supply to the Genie camera and an Ethernet cable from the Genie to the host computer. Once
communication with the host computer is started the automatic IP configuration sequence will assign an LLA IP
address as described in section "Genie IP Configuration Sequence" on page 23, or a DHCP IP address if a DHCP
server is present on your network. The factory defaults for Genie is Persistent IP disabled and DHCP enabled with
LLA always enabled as per the GigE Vision specification. For additional information see "IP Configuration Mode
Details" on page 77. See the next section "Connectors" on page 21 for an overview of the Genie interfaces.
Connectors
The Genie has only two connectors:
•
A single RJ45 Ethernet connector for control and video data transmitted to/from the host computer Gigabit
•
A single 12-pin Hirose male connector for camera power plus trigger, strobe and general I/O signals. The
suggested female cable mating connector is Hirose model HR10A-10P-12S.
The Genie has one multicolor LED to provide a simple visible indication of camera state (see figure below and
section "Status LED Codes" on page 22). Additionally the RJ45 has two LEDs for network status conditions.
The following figure of the Genie back end shows connector and LED locations. See "Mechanical Specifications"
on page 89 for details on the Genie connectors and camera mounting dimensions.

Status LED Codes
The camera is equipped with a LED to display the operational status of the camera. When more than one condition
is active, the LED color indicates the condition with the highest priority (such as an acquisition in progress has more
priority than a valid IP address assignment). The following table summarizes the LED states and corresponding
camera status.

Once the Genie has its RJ45 connected to a network, the Status LED will turn to steady blue when the IP address is
assigned. Only at this time will it be possible by the GigE Server or any application to communicate with the
camera.
Note: Even if the Genie has obtained an IP address, it might be on a different subnet than the NIC it is attached to.
Therefore, if the Genie LED is blue but an application such as CamExpert can not see it, this indicates a network
configuration problem.

Genie IP Configuration Sequence
The Genie IP (Internet Protocol) Configuration sequence to assign an IP address is executed automatically on
camera power-up or when connected to a network. As a GigE Vision compliant device, Genie attempts to assign an
IP address as follows.
For any GigE Vision device, the IP configuration protocol sequence is:
•
•
•
Persistent IP (if enabled)
DHCP (if a DHCP server is present)
Link-Local Address (always enabled)
The factory defaults for Genie is Persistent IP disabled and DHCP enabled with LLA always enabled as per the
GigE Vision specification. For additional information see "IP Configuration Mode Details" on page 77.
GigE Server Status
Once the Genie is assigned an IP address (its Status LED is steady blue) the GigE server tray icon will not have a
red X through it, indicating that the Genie device was found. It might take a few seconds for the GigE Server to
refresh its state after the Genie has obtained an IP address.
Right-click the GigE Server tray icon to open the following menu.
Click on Status to open a window listing all devices connected to the host system. Each GigE device is listed by
name along with important information such as the assigned IP address and device MAC address. The screen shot
below shows a connected Genie with no networking problems.

In the event that the device is physically connected, but the Sapera GigE Server icon is indicating that the connected
device is not recognized, click Scan Network to restart the discovery process. Note that the GigE server
periodically scans the network automatically to refresh its state. See "Troubleshooting" on page 101 for network
problems.
Optimizing the Network Adapter used with Genie
Most Gigabit network interface controllers (NIC) allow user modifications to parameters such as Adapter Buffers
and Jumbo Frames. These should be optimized for use with the Genie during the installation.
Increasing Adapter Buffers and Jumbo Frames
Adapter Buffers (receive descriptors): Under certain conditions the host PC system CPU may be very busy with
tasks other than the imaging application. Incoming image packets remain in the PC memory allocated to store
packets instead of immediately being copied into the image buffer. By increasing the NIC host buffers, more
incoming image packets can be stored by the NIC before it must start discarding them. This provides more time for
the PC to switch tasks and move image packets to the image buffer.
Not all network boards allow increasing their buffer count and even among those that do, such as the Intel NIC,
different versions will have different maximum receive descriptor values. Refer to the NIC user documentation for
details on configuring this parameter. The procedure in this section shows how to increase the number of packet
buffers for one version of Intel network adapter.
Jumbo Frames: With good gigabit Ethernet connections with minimal packet resend conditions, host computer
performance can be further improved by increasing the data packet size. Each streaming video packet causes an
interrupt in the host computer. Therefore increasing the packet size reduces the CPU usage percentage required to
handle video data from Genie.
Before the Genie is configured to use larger data packets, the NIC used with the Genie must be configured to allow
Jumbo Frames. The procedure in this section describes increasing the size of Jumbo Frames for one version of Intel
network adapter.
The screenshot below shows that the Genie device was found and there is no IP conflict. The Maximum Packet Size
field is highlighted in yellow, indicating that Jumbo Frames are not enabled on the NIC used with the Genie or that
the control application is forcing a safe packet size. Using a larger packet size improves host CPU performance,
which can be critical when using multiple Genie devices. Note that the Maximum Packet Size field is updated only
when an application such as CamExpert communicates with the Genie.

Running the Network Configuration Tool
Once the GigE Server discovers a device, start the Network Configuration tool to verify and modify the network
First verify the Genie camera appears as a child of the NIC card it is connected to. By default the Genie camera is
identified by its serial number if no user-defined name has been assigned.
Because image transfers require considerable bandwidth through the NIC, it is recommended that a separate Gigabit
Ethernet NIC for the Genie camera be used. Connections to the Internet or to a corporate network should be through
a different NIC.

switch, testing the installation with CamExpert is a straightforward procedure.
•
•
Start Sapera CamExpert by double clicking the desktop icon created during the Genie software installation.
CamExpert will search for installed Sapera devices. In the Device list area on the left side, the connected Genie
camera is shown or will be listed in a few seconds after CamExpert completes the automatic device search
(device discovery).

About the User-Defined Camera Name
The Genie can be programmed with a user-defined name to aid identifying multiple cameras connected to the
network. For instance, on an inspection system with 4 cameras, the first camera might be labeled “top view”, the
second “left view”, the third “right view” and the last one “bottom view”. The factory default user name is set to
match the camera serial number for quick initial identification. Note that the factory programmed Genie serial
number and MAC address are not user changeable.
When using CamExpert, multiple Genie cameras on the network are seen as different "Genie_M640_x" devices.
Click on a Genie device user name to select it for control by CamExpert.
An imaging application uses any one of these attributes to identify a camera: its IP address, MAC address, serial
number or User Name. Some important considerations are listed below.
•
•
•
Do not use the camera's IP address as identification (unless it is a persistent IP) since it can change with each
power cycle.
A MAC address is unique to a single camera, therefore the control application is limited to the vision system
with that unique camera.
The User Name can be freely programmed to clearly represent the camera usage. This scheme is recommended
for an application to identify cameras. In this case, the vision system can be duplicated any number of times
with cameras identified by their function, not their serial numbers or MAC address.

Gain and Black Level Controls
The Genie series of monochrome cameras provide gain and black level adjustments for the analog signal from each
CCD pixel, before the analog to digital conversion. The software gain and black level controls can make small
compensations to the acquisition in situations where lighting varies and the lens iris can not be easily adjusted. The
user can evaluate Gain and Black Level by using CamExpert.
Features and limitations are described below.
•
Gain is expressed in decibels (dB). Range from -6dB to +12dB in 0.1dB increments. Gain is a multiplication
factor to the analog signal (i.e. exposure) before digitization.
Note that a gain of 6dB is a multiplier of 2 (doubles the level).
•
•
•
•
•
Increasing gain increases the amplitude of the analog video signal but also increases the sensor analog noise
proportionately, before analog to digital conversion.
Note: Doubling gain does not necessarily double the digital data due to the Black Level Offset value as
described below.
Black level offset is applied to the sensor analog signal to shift the DC level of the video signal. Black level is
an additive offset to the analog video signal before digitization.
Black level offset increases the brightness of the video signal equally. Therefore any area of the video that is
black will brighten to some gray level as offset is increased.
Black level offset is expressed as a number ranging from -128 to 127. The offset is achieved as a change in the
analog signal from the sensor where a control number change of 1 is 1/16th of a DN (digital number) pixel
change. In other words, a control change of 16 is required for each change in pixel value, therefore a maximum
control value of 127 will cause a black pixel (00) to have a gray value of about 8.
•
The resultant output Gain/Offset formula is
OutputData =
where : Gain = 20log(multiplier)
(
Exposure*Gain + Offset
)
Gain and Offset Control via Sapera LT or GenICam Applications

Partial Scan (horizontal cropping)
Genie also can crop the acquisition horizontally by grabbing less pixels on each horizontal line. Additionally a
horizontal offset value will start the grab from any pixel count, as shown in the following figure. Note that
horizontal cropping does not increase the maximum frame rate due to the CCD readout architecture.

Window ROI
Vertical and Horizontal Cropping can be combined to grab only a region of interest (ROI). Besides eliminating post
acquisition image cropping done by software in the host computer, a windowed ROI grab reduces the bandwidth
required on the Gigabit Ethernet link since less pixels are transmitted. See "CamExpert Image Buffer and ROI

Binning
Binning is the process where the charge on two (or more) adjacent pixels is combined. This results in increased light
sensitivity since there is twice the sensor area to capture photons. The sensor spatial resolution is reduced but the
improved low-light sensitivity plus lower signal-noise ratio may solve a difficult imaging situation. The user can
evaluate binning by using CamExpert.
Genie supports horizontal and vertical binning independently, by a factor of 2 in each axis. Specifically if horizontal
binning only is activated, a nominal 640x480 image is reduced to 320x480. If vertical binning only is activated, the

Trigger Modes
Genie image exposures are initiated by an event. The trigger event is either the camera's programmable internal
clock used in free running mode, an external input used for synchronizing exposures to external triggers, or a
programmed function call message by the controlling computer. These triggering modes are described below.
•
Free running (trigger disabled): The Genie free-running mode has a programmable internal timer for frame
rate and a programmable exposure period. Frame rate is 0.1 fps to the maximum supported by the sensor.
Exposures range from 100 µs to a maximum also dependent on the current frame rate. This always uses
Synchronous mode where exposure is aligned to the sensor horizontal line timing.
•
•
External trigger: Exposures are controlled by an external trigger signal. External signals are isolated by an
following section provides information on external trigger timing.
Software trigger: An exposure trigger is sent as a control command via the Ethernet network connection.
Software triggers can not be considered time accurate due to network latency and sequential command jitter.
But a software trigger is more responsive than calling a single-frame acquisition (Snap command) since the
latter must validate the acquisition parameters and modify on-board buffer allocation if the buffer size has
changed since the last acquisition.

Exposure Controls
Exposure Control modes define the method and timing of how to control the sensor integration period. The
integration period is the amount of time the sensor is exposed to incoming light before the video frame data is
transmitted to the controlling computer.
•
•
Exposure control is defined as the start of exposure and exposure duration.
The start of exposure can be an internal timer signal (free-running mode), an external trigger signal, or a
software function call trigger.
•
•
The exposure duration can be programmable (such as the case of an internal timer) or controlled by the external
trigger pulse width.
For the Genie camera, exposure control modes are "Free-running Programmable Exposure" on page 43 (timer),
Free-running Programmable Exposure
Genie is in a multifunctional free running mode with the following features:
•
•
Internal trigger programmable from maximum sensor frame rate down to 0.1Hz.
Exposure duration is user programmable (exposure maximum is dependent on the frame rate). Minimum
exposure is 100µs.
•
•
Supports vertical and horizontal binning.
Exposure synchronization timing is "Synchronous Mode" on page 46 where the exposure is aligned with the
sensor horizontal line timing and the next acquisition is triggered by an internal programmable timer.
•
Image readout is simultaneous where the grabbed image frame is readout during the next frame exposure time.
This allows for fastest possible frame rates. See the timing diagram below.

Synchronization Timing
Genie supports two types of sensor synchronization used to align the exposure to sensor timing:
•
•
Synchronous Mode: Exposure is synchronous to the line timing of the sensor. Exposure granularity is 1µs and
the readout can be concurrent to the exposure for the fastest possible frame rate.
Reset Mode: Timing is reset to initiate exposure of next frame. Exposure granularity is 1µs, but readout must
be sequential to exposure, reducing the maximum achievable frame rate.
Synchronous Mode
•
Synchronous mode starts the exposure period aligned to the sensor horizontal line timing and the programmable
duration granularity is 1µs.
•
•
•
In the case of the Genie M640, a horizontal line occurs every 31.77µs.
Exposure duration is from a minimum of 100µs up to 4 sec.
In this mode, sensor exposure and sensor readout of the previous frame's exposure occur simultaneously. This
allows operating the sensor up to its maximum frame rate.
•
•
Any trigger received before the end of the exposure is ignored. The application can elect to receive messages
Since the external trigger is asynchronous with the Genie horizontal line timing, the frame exposure start is
subject to 1 horizontal line jitter.

•
Exposure starts immediately after a valid trigger. There is no jitter on the start of exposure.
Exposure time is programmable or controlled by the trigger pulse width.
Minimum exposure is 100 µs – maximum is 4 seconds, with control steps of 1µs.
Sensor readout must complete before the next exposure can start. That is, exposure and readout are sequential.
Therefore, the maximum frame rate is lower than for Synchronous mode.

General Inputs
External Input Signal Opto-coupler & Debounce Circuit
•
Genie provides two sets of opto-coupled inputs for either RS422 or TTL signals. These can be used as external
trigger sources.
•
See "12-Pin Hirose Connector Signal Details" on page 90 for connector pinout and electrical information. The
cable shell and shield should electrically connect the Genie chassis to computer chassis for maximum EMI
protection.
•
•
•
For external triggers, a rising edge signal is suggested to minimize the time it takes for the opto-coupler to
change state. (The opto-coupler response time is typically 10µs for rising edge compared to 50μs for falling
edge).
Each input incorporates a signal debounce circuit (following the opto-couple) to eliminate short noise
transitions that could be wrongly interpreted as a valid pulse. The duration is user-programmable from 1µs to
255µs with CamExpert.
Note, the external trigger input propagation delay is dependent on the signal used to activate the opto-coupled
input. Typical delays are 3 µs for Active Open and 5 µs for Active Close.
General Inputs: Settings Via CamExpert
CamExpert provides control of inputs via the I/O Controls Parameters tab. The Input Settings dialog box allows
you to view the signal and status for each pin on the Hirose connector. The Polarity drop-down list boxes, located
in the INPUT Settings area, allow you to specify the polarity of the Input 1 and Input 2 as either Active High or
Active Low. The Minimum duration field for each input, allows you to specify the minimum trigger length (1-
255µs ) so that input transitions are debounced to prevent unwanted trigger events.

Strobe and General Outputs
Genie provides two sets of opto-coupled outputs (see "External Outputs" on page 92). These can be used as a strobe
signal to control lighting or to generate programmable pulses when specific events are generated by the camera.
They can also be set to a static state (close or open) by the application.
See "12-Pin Hirose Connector Signal Details" on page 90 for connector pinout and electrical information.
General Outputs: Settings via CamExpert
The Output Settings dialog box allows you to configure the event mode for both output 1 and output 2. Each
output can be set independently to one of the available event modes. A typical usage of output is to control a strobe
light in relation to the camera exposure. Select the output to configure by clicking on the Output 1 or Output 2
buttons located at the top of the dialog box. Use the Event mode drop-down list box to select the required event
mode.

When an event mode is selected, its trigger output schematic or signal timing diagram is displayed, as well as any
other additional parameters for the mode.
For most event modes, the trigger output signal can be set to either Active Open (that is high with the load
connected to a voltage source) or Active Closed (where current is drawn through the load). The output delay can be
set from 0 to 4 seconds, in increments of 1 µs. The pulse duration can be set from 100µs to 4 seconds, in increments
of 1 µs.

Flat Field (Image Shading) Correction
Image Shading correction, also know as Flat Field Correction is the process of eliminating small gain differences
between pixels in a sensor array. That sensor when exposed to a uniformly lit field will have no gray level
differences between pixels when calibrated flat field correction is applied to the image. The Genie camera stores flat
field correction data until power off or in its user setting state for recall at any time (see "Power-up Configuration"
on page 32). Flat field correction data is composed of 8 bit gain and 8 bit offset coefficients.
The CamExpert Flat Field Correction tool allows calibrating. saving, and loading the flat field calibration data for
any Genie camera being controlled.
Before performing calibration, verify Genie acquisition with a live grab. Also at this time make preparations to grab
a flat light gray level image, required for the calibration, such as a clean evenly lighted white wall or non-glossy
paper. Note the lens iris position for a white but not saturated image. Additionally check that the lens iris closes well
or have a lens cover to grab the dark calibration image.
Flat Field Correction Calibration Procedure
Calibration is the process of taking two reference images, one of a black field – one of a light gray field (not
saturated), to generate correction data for images captured by Genie. Each sensor pixel data is modified by the
correction factor generated by the calibration process, so that each pixel now has an identical response to the same
illumination.
Start the Flat Field calibration tool via the CamExpert menu bar:
Pre-processing • Flat Field Correction • Calibration.
Flat Field Calibration Window
The Flat Field calibration window provides a three step process to acquire two reference images and then save the
flat field correction data for the Genie used. To aid in determining if the reference images are valid, a histogram tool
is provided so that the user can review the images used for the correction data.

Internal Image Test Patterns
The Genie camera includes a built in test pattern generator that can be used to confirm camera Ethernet connections
or driver installations, without the need for a camera lens or proper lighting. The pattern generator inserts video just
after the sensor A/D converter, therefore Genie processing such as the LUT act on the generator images or on sensor
images.
CamExpert is used to easily enable and select the Genie test patterns. As shown in the following figure, select the
Sensor tab, then select one of the four patterns from the drop menu. Select live grab to see the pattern output.
Genie Test Pattern Selection – on Sensor Tab
The Genie test patterns are:
•
Horizontal ramp: successive pixel's gray level is incremented by 1 to maximum pixel value then repeated until
the end of line. The gray level is reset to 0 on the following line.
•
•
Vertical ramp: similar to the horizontal ramp, successive lines are incremented by 1 gray level then repeated
for the full frame.
Moving diagonal ramp: combination of the 2 previous schemes, but first pixel in image is incremented by 1
between successive frames. This is a good pattern to indicate motion when doing a continuous grab.
•
Purity: a purity pattern where all pixels have the same value. The gray value is incremented by one on
successive frames to maximum then repeated. This also provides motion for live grabs.

size to the maximum value as reported by the NIC driver. If this does not provide satisfactory performance, it is
possible to optimize transfers by manually setting the network configuration parameters. The following screen shot
of the GigE Vision Parameters shows the CamExpert control set to Manual. Descriptions for each parameter
follow.

Parameter
Description
Network Configuration Mode
Specifies the Network Configuration Mode as either Automatic, Manual, or Optimize. In
general use Optimize mode. Some computers, especially laptops, may require manual
optimization of network parameters.
The following parameters can be modified when Manual mode is selected.
Inter-Packet Delay (in sec)
Packet Size (in bytes)
Specifies the inter-packet delay, in sec. The range of permitted values is 0.000000 to
0.065535. The inter-packet delay is the minimum time interval between two successive
packets. This can be increased if the NIC is unable to keep up with packet arrivals (thus
dropping packets–seen as video noise).
Specifies the maximum packet size, in bytes. The range of possible values is 576 to 1500,
in increments of 4 bytes when the NIC does not support jumbo packet. The maximum is
use the largest possible packet size supported by your network elements. In order to
support jumbo packets, all intermediate network elements must support them, otherwise
they will simply be silently discarded and no image data will reach the PC.
Heartbeat Timeout (in Sec)
Maximum Packet Resend
Specifies the heartbeat timeout, in seconds. The range of permitted values is 0.5 to 65, in
increments of 0.001 seconds. This is used by the camera to ensure the PC application is
still linked. If the heartbeat timeout expires, the camera will shutdown the connection to
the current application.
Sets the percentage of packets that can be resent for each frame. This is used to ensure
the streaming data (including resends) does not exceed the Ethernet link capacity. As an
example, a system capturing at 80 MB/s can allow 25% of packet resends without
exceeding 100 MB/s (about the maximum capacity of a gigabit Ethernet link).
Network Controls via Sapera LT or GenICam Applications
Genie Sapera parameters for Network Configuration:
NetworkConfigurationMode = {Automatic = 0, Manual = 1}
InterPacketDelay = Minimum delay in µs between image packets
PacketSize = Image packet size in bytes
HeartbeatTimeout = Heartbeat period (watchdog) in ms before camera disconnect
MaximumPacketResend = Sets percentage of packets that can be resent per frame
Sapera
In CamExpert, these parameters are available under the “GigE Vision” tab.
GenICam features for Network Configuration:
PayloadSize = Size of the payload in bytes. This is the total number of bytes sent in the payload.
No packet headers.
Other networks parameters may be available through the 3rd party package used.

Genie Power-up Configuration
On power up the Genie camera initializes to a factory default state which sets the camera with neutral parameters
and in free run mode. The default state ensures that the camera is ready for acquisition. Genie also provides storage
for one user-defined state. This user state allows quick camera configuration for a known repeatable imaging
system. The following table describes the camera parameters stored in the user state. See "Power-up Configuration"
on page 32 for information on saving the user state with CamExpert.

Feature Type INT32
The feature list for type INT32 has an additional column 'Exponent' which defines the feature's native unit. This
exponent value is used as a unit multiplier so that the feature value is expressed as an integer, not a decimal number.
•
As an example from the following table, the Genie frame rate is 60000 with an exponent of 3. Therefore the
frame rate native unit is mHz. The current value shown – 60000 mHz, is actually 60.000 Hz.

Network Tools
IP Configuration Mode Details
The following descriptions provide more information on the IP configuration modes supported by Genie. In general
automatic IP configuration assignment is sufficient for most Genie installations.
Link-Local Address (LLA)
•
LLA is also known as Auto-IP. It is used for unmanaged networks including direct connections from a GigE
Vision device to a dedicated NIC.
•
•
A subnet configured with LLA cannot send packets across routers but only via Ethernet switches.
LLA is the recommended scheme when only one NIC is connected to GigE cameras. LLA is fully automatic
requiring no user input.
Ensure only one NIC is using LLA on your PC, otherwise IP conflicts will result.
•
•
The NIC will automatically assign a random IP address within the 169.254.x.x subnet. The LLA protocol
ensures there are no conflicts with other devices through an arbitration scheme.
The Windows NIC configuration must be set to DHCP (the typical default case) and no DHCP server must be
present on the network. Otherwise, an IP address gets assigned by the DHCP server. Windows will turn to LLA
when no DHCP server answers requests coming from the NIC.
•
Windows takes up to 1 minute to obtain an LLA IP address. With Windows XP, with no DHCP server
involved, the network adapter icon in the system tray (in Windows XP) typically shows "limited or no
connectivity".
This is normal (see Microsoft KB article #892896) and indicates that the network does not have connectivity
beyond routers.
•
•
Windows and Genie are still running the DHCP process in the background. If a DHCP server becomes
available on the network, the NIC will get a DHCP assigned IP address for the connected device but
connections on the LLA IP address will be lost.
Important: If the host system has multiple NIC devices configured with LLA, then the communication stack
cannot accurately resolve which NIC to forward an IP packet on the 169.254 segment. Limit the number of NIC
configured using LLA to one interface. See "GigE Server Warning Example 1a: IP error with multiple NICs"
on page 103 for additional information.
•
Use the DALSA Network tool to change the Genie from the default DHCP/LLA mode to Persistent IP mode
when required, such as when there are multiple NIC devices with Genie connected to each. Note that DALSA
recommends DHCP/LLA as the mode of operation where a switch is used to connect multiple Genie devices.

DHCP (Dynamic Host Configuration Protocol)
•
This Genie IP configuration mode requires a DHCP server to allocate an IP address dynamically. The Genie
must be configured to have DHCP enabled. This is the factory default settings.
•
The DHCP server is part of a managed network. Windows XP itself does not provide a DHCP server function.
A dedicated DHCP server is required. Open-source DHCP server software can be found on the Internet, but
they might not provide the same level of functionality as commercial-grade DHCP servers.
•
A DHCP server is recommended where there are multiple NIC ports with multiple GigE Vision devices
attached. Each NIC ports must use a different subnet to avoid IP address conflicts (see "GigE Server Warning
•
•
Under Windows, a NIC is configured in DHCP mode by default. If no DHCP server is present on a given
subnet, Windows will revert to LLA as explained in the section above.
Ensure that a different subnet is assigned to each NIC on the network. Typical ranges are 192.200.x.x or
10.10.x.x for internal networks.
Persistent IP
•
This protocol is only suggested if the user fully controls the assignment of IP addresses on the network and a
GigE Vision camera is connected beyond routers.
•
The GigE Vision camera is forced a static IP address. The NIC IP address must use the same subnet otherwise
the camera is not accessible.
•
•
•
If the Genie camera is connected to a network with a different subnet, it cannot be accessed.
The DALSA network configuration tool is used to set a persistent IP address.
An example of a Persistent IP address assignment:
•
•
•
Persistent IP = 192.200.1.1
Subnet Mask = 255.255.0.0
Default Gateway = 0.0.0.0
•
•
Warning: an incorrect IP address assignment might make it impossible to connect to the camera. In such a case
the DALSA network configuration tool includes a function to recover a Genie camera with an unknown
persistent IP and set the Genie to the factory default setting, i.e. DHCP/LLA mode. The Genie MAC address
must be known to use this function. See "Recovering a Camera with an Unknown Persistent IP" on page 82 and
For GigE Vision applications the FORCEIP command is used to force a new persistent IP or to change the IP
configuration protocol. The Genie MAC address must be known to use the FORCEIP command.

Network Configuration Tool
The Network Configuration tool provides information on all network adapters installed in the system and any
connected GigE Vision devices. For the Genie, the tool allows a simple method to assign a User-Defined name and
also to set a Persistent IP address instead of the default DHCP/LLA assigned IP address. Using this tool, Genie
network configurations can be easily made without having to use any Windows Control Panel application.
Important: Any changes made with this tool will update the Genie flash memory. Do not remove power from the
Genie camera for a minimum 10 seconds. Then cycle the Genie power to load the new flash settings.
Quick Genie Network Configuration
•
Start the Network Configuration program from the windows start menu: Start•Programs•DALSA•Sapera
Network Imaging Package•DALSA Network Configuration Tool.
•
•
The left display window will show all installed network adapters and any connected Genie camera.
Click on a Genie camera to see information such as MAC address, current IP address, serial and firmware
numbers.
•
Click in the User Defined Name edit box and change the Genie name as required. Click on the Update button to
write into the Genie memory.
Genie Network Information
•
•
Select the Device Configuration tab to switch from the default IP configuration mode DHCP/LLA to
Persistent IP mode (only if required).
With Persistent IP mode selected enter the desired IP address, subnet mask, and default gateway.
Important: do not forget the persistent IP address you assign, else the camera can not be controlled.

Genie IP Configuration
System Information and Configuration
Select the system icon (the computer symbol) in the left pane to display current system information which may be
required when documenting Genie installations. There are no user changeable fields in the System Information tab.
In the right hand pane click on the System Configuration tab. By default the Sapera GigE Server is added to the
Windows Firewall exception list. This function is performed automatically when the Genie software package is
installed. This ensures the Windows Firewall remains active (if it was enabled) without having to individually put
each Genie application program in the exception list.
System Firewall Configuration
If the computer is using a different firewall software package, refer to that firewall's software manual to allow the
Sapera GigE Server to have access through it.
Alternatively, it is possible to exclude a specified NIC from using the firewall. The NIC dedicated to the Genie
camera does not need Windows firewall. See "Disabling Windows Firewall" on page 107 for details on excluding a
NIC from firewall settings.

Network Card Information and Configuration
Select a network card icon in the left pane to see the NIC configuration parameters. The Network Configuration tool
ensures that no two NIC devices installed in the computer are on the same subnet, since that would create a conflict.
A warning message is displayed in such a case, indicating that a settings change is required for one of the NIC.
NIC Information
NIC IP and Network Imaging Driver Assignment
For each NIC, it is possible to configure the IP configuration mode (either DHCP/LLA or Persistent IP) if required
via the NIC Configuration tab.
Warning: Changing the NIC IP address may put it on a different subnet than the Genie. Changing the NIC IP
configuration first might cause the case where the camera becomes inaccessible from the NIC.
The proper sequence is to first change the camera IP configuration then change the NIC IP.

After installation, all system NIC devices have the Sapera Network Imaging driver enabled. Only the NIC
connected to a Genie camera requires the Network Imaging driver enabled to capture images from Genie. The
Network Imaging driver streams image data efficiently to image buffers.
Select other NIC devices in the system and disable the Network Imaging Driver if they are not used with a Genie
camera.
Recovering a Camera with an Unknown Persistent IP
When a Genie camera has been configured with a persistent IP address, that camera can not be controlled if its IP
address has been lost or forgotten. The DALSA Network Configuration tool provides a function to recover cameras
and reset them back to the DHCP/LLA mode. The camera can also be set to a new persistent IP address immediately
if required.
Important: To recover a Genie camera, the camera MAC address must be known. DALSA ships all Genie
cameras with a label stating its serial number and MAC address. Additionally the NIC connected to the Genie
must be configured for LLA mode.
To recover a Genie:
•
Start the Network Configuration program from the windows start menu: Start•Programs•DALSA•Network
Interface•DALSA Network Configuration Tool.
•
•
From the menu bar click on Advanced and then on Recover Camera.
On the dialog enter the camera MAC address and click the Recover Camera button.

If the camera requires a persistent IP address, select the bullet to assign a persistent IP immediately with
recovery. Enter the new IP address and click on Recover Camera.
Important: Any changes made with this tool will update the Genie flash memory. Do not remove power from the
Genie camera for a minimum 10 seconds.
Sapera GigE Server Details
This section provides additional details on the GigE Server not covered in the Genie installation section of this
manual. Generally the Genie automatic installation requires no user intervention.
•
•
•
•
•
The Sapera GigE Server implements the GigE Vision Control Protocol (GVCP). This provides the interface to
generate GVCP messages to control and configure a GigE Vision device.
GigE Server handles the heartbeat messages, allowing an application in development, to be single-stepped
while in debug mode, without loss of the camera connection.
GigE Server is a single application going through the firewall. This simplifies firewall settings as only this
application needs to be listed in the firewall exceptions.
The GigE Server periodically rescans the network to discover any new camera that might have been added to
the network. This will also identify devices removed.
When required, it is possible to disabled the GigE server. A Sapera application will then directly be linked to
the library responsible for GigE Vision control channel communications. This can be used to minimize inter-
process communications.

Using CamExpert with Genie Monochrome Cameras
CamExpert is the camera interfacing tool supported by the Sapera library. When used with a Genie camera,
CamExpert allows a user to test all Genie operating modes. Additionally CamExpert saves the Genie user settings
configuration to the camera or saves multiple configurations as individual camera parameter files on the host system
(*.ccf).
An important component of CamExpert is its live acquisition display window which allows immediate verification
of timing or control parameters without the need to run a separate acquisition program.
For context sensitive help, click on the
button then click on a camera configuration parameter. A short

The Genie LAN connector is a standard Ethernet socket. Use CAT5e or CAT6 certified Ethernet cables. CAT5e
cable is rated for 100 MHz spectral bandwidth but CAT6 cable is rated for a 200 MHz spectral bandwidth with less
signal attenuation, therefore strongly recommended for long connection lengths.
The interconnection Ethernet cable can be either Straight Through or Crossover cable type. The Gigabit Ethernet
standard for devices defines that they will auto-negotiate send and receive channels, eliminating the need for users
to use a specific Ethernet cable type.

Optical Considerations
This section provides an overview to illumination, light sources, filters, lens modeling, and lens magnification. Each
of these components contribute to the successful design of an imaging solution.
Illumination
The amount and wavelengths of light required to capture useful images depend on the particular application. Factors
include the nature, speed, and spectral characteristics of objects being imaged, exposure times, light source
characteristics, environmental and acquisition system specifics, and more. The DALSA Web site,
http://vfm.dalsa.com/, provides an introduction to this potentially complicated issue. Click on the Application
Support link and then select the CCD Technology Primer. Review “Radiometry and Photo Responsivity” along
with other sections of interest.
It is often more important to consider exposure than illumination. The total amount of energy (which is related to
the total number of photons reaching the sensor) is more important than the rate at which it arrives. For example,
5μJ/cm2 can be achieved by exposing 5mW/cm2 for 1ms just the same as exposing an intensity of 5W/cm2 for 1μs.
Light Sources
Keep these guidelines in mind when selecting and setting up light source:
•
LED light sources are relatively inexpensive, provide a uniform field, and longer life span compared to other
light sources. However, they also require a camera with excellent sensitivity.
•
•
Halogen light sources generally provide very little blue relative to infrared light (IR).
Fiber-optic light distribution systems generally transmit very little blue relative to IR.
Genie Monochrome Series-GigE Vision Camera
Technical Specifications • 93
Download from Www.Somanuals.com. All Manuals Search And Download.
•
Some light sources age such that over their life span they produce less light. This aging may not be uniform—a
light source may produce progressively less light in some areas of the spectrum but not others.
Filters
CCD cameras are extremely responsive to infrared (IR) wavelengths of light. To prevent infrared from distorting the
images you scan, use a “hot mirror” or IR cutoff filter that transmits visible wavelengths but does not transmit
wavelengths over 750nm. Examples are the Schneider Optics™ B+W 489, which includes a mounting ring, the
CORION™ LS-750, which does not include a mounting ring, and the CORION™ HR-750 series hot mirror.
Lens Modeling
Any lens surrounded by air can be modeled for camera purposes using three primary points: the first and second
principal points and the second focal point. The primary points for a lens should be available from the lens data
sheet or from the lens manufacturer. Primed quantities denote characteristics of the image side of the lens. That is, h
is the object height and h′ is the image height.
The focal point is the point at which the image of an infinitely distant object is brought to focus. The effective focal
length (f′) is the distance from the second principal point to the second focal point. The back focal length (BFL) is
the distance from the image side of the lens surface to the second focal point. The object distance (OD) is the
distance from the first principal point to the object.
Primary Points in a Lens System
Magnification and Resolution
The magnification of a lens is the ratio of the image size to the object size:
Where m is the magnification, h’ is the image height (pixel size)
and h is the object height (desired object resolution size).
h'
m =
h
By similar triangles, the magnification is alternatively given by:
f '
m =
OD
These equations can be combined to give their most useful form:
This is the governing equation for many object and image plane
parameters.

Example: An acquisition system has a 512 x 512 element, 10μm pixel pitch area scan camera, a lens with an
effective focal length of 45mm, and requires that 100μm in the object space correspond to each pixel in the image
sensor. Using the preceding equation, the object distance must be 450mm (0.450m).
OD = 450mm(0.450m)

Sensor Handling Instructions
This section reviews proper procedures for handling, cleaning, or storing the Genie camera. Specifically the Genie
CCD sensor needs to be kept clean and away from static discharge to maintain design performance.
Electrostatic Discharge and the CCD Sensor
Cameras contain charge-coupled device (CCD) image sensors, which are metal oxide semiconductor (MOS) devices
and are susceptible to damage from electrostatic discharge (ESD).
Electrostatic charge introduced to the sensor window surface can induce charge buildup on the underside of the
window that cannot be readily dissipated by the dry nitrogen gas in the sensor package cavity. When charge buildup
occurs, surface-gated photodiodes (SGPDs) may exhibit higher image lag or a highly non-uniform response, with
some pixels displaying a much higher response when the sensor is exposed to uniform illumination. The charge
normally dissipates within 24 hours and the sensor returns to normal operation.
Important: Charge buildup will affect the camera’s flat-field correction calibration. To avoid an erroneous
calibration, ensure that you perform flat-field correction only after a charge buildup has dissipated over 24 hours.
Protecting Against Dust, Oil and Scratches
The CCD window is part of the optical path and should be handled like other optical components, with extreme
care.
Dust can obscure pixels, producing dark patches on the sensor response. Dust is most visible when the illumination
is collimated. The dark patches shift position as the angle of illumination changes. Dust is normally not visible when
the sensor is positioned at the exit port of an integrating sphere, where the illumination is diffuse.
Dust can normally be removed by blowing the window surface using a compressed air blower, unless the dust
particles are being held by an electrostatic charge, in which case either an ionized air blower or wet cleaning is
necessary.
Oil is usually introduced during handling. Touching the surface of the window barehanded will leave oily residues.
Using rubber finger cots and rubber gloves can prevent oil contamination. However, the friction between the rubber
and the window may produce electrostatic charge that may damage the sensor.
Scratches can be caused by improper handling, cleaning or storage of the camera. When handling or storing the
Genie camera without a lens, always install the C-mount protective cap. Scratches diffract incident illumination.
When exposed to uniform illumination, a sensor with a scratched window will normally have brighter pixels
adjacent to darker pixels. The location of these pixels changes with the angle of illumination.

Cleaning the Sensor Window
Even with careful handling, the sensor window may need cleaning. The following steps describe various cleaning
techniques to clean minor dust particles to accidental finger touches.
•
Use compressed air to blow off loose particles. This step alone is usually sufficient to clean the sensor window.
Avoid moving or shaking the compressed air container and use short bursts of air while moving the camera in
the air stream. Agitating the container will cause condensation to form in the air stream. Long air bursts will
chill the sensor window causing more condensation. Condensation, even when left to dry naturally, will deposit
more particles on the sensor.
•
When compressed air cannot clean the sensor, Dalsa recommends using lint-free ESD-safe cloth wipers that do
not contain particles that can scratch the window. The Anticon Gold 9”x 9” wiper made by Milliken is both
ESD safe and suitable for class 100 environments. Another ESD acceptable wiper is the TX4025 from
Texwipe.
•
•
An alternative to ESD-safe cloth wipers is Transplex swabs that have desirable ESD properties. There are
several varieties available from Texwipe. Do not use regular cotton swabs, since these can introduce static
charge to the window surface.
Wipe the window carefully and slowly when using these products.

Ambient Temperature:
0° to 45° C (operation)
0° to 70° C (storage)
Relative Humidity:

Computer Requirements for Genie Cameras
The following information is a guide to computer and networking equipment required to support the Genie camera
at maximum performance. The Genie camera series complies with the current IPv4 Internet Protocol, therefore
current Gigabit Ethernet (GigE) equipment should provide trouble free performance.
Host PC System
•
•
Pentium 4 system (or AMD equivalent) with 512 MB system memory.
System motherboard without an embedded graphic card. Avoid using onboard video cards as they may
compete with other components for shared memory.
•
•
High performance video card as either an AGP bus or PCI Express bus.
Operating System: Windows 2000 SP1 and Windows XP are supported.
Network Adapters
•
GigE network adapter (either add on card or on motherboard). The Intel PRO/1000 MT adapter is an
example of a high performance NIC. Typically a system will need an Ethernet GigE adapter to supplement
the single NIC on the motherboard.
•
•
PCI Express adapters will outperform PCI adapters.
Network adapters that support Jumbo Frames will outperform adapters with fixed packet size frames.
Laptop Information
Laptop computers with built in GigE network adapters may still not be able to stream full frame rates
•
from Genie. Thorough testing is required with any laptop computer to determine the maximum frame rate
Ethernet Switch Requirements
When there is more than one device on the same network or a camera-to-PC separation greater than 100 meters, an
Ethernet switch is required. Since the Genie GigE camera complies with the Internet Protocol, it should work with
all standard Ethernet switches. However, switches offer a range of functions and performance grades, so care must
be taken to choose the right switch for a particular application. The following switches are expected to work with
the camera but manufacturers may change specifications and features at anytime:
•
Features Layer 2 with IGMP v2.0 that supports jumbo frames and multicast.
SMC EZ Switch (SMCGS8): low cost switch supporting jumbo frames.
Features Layer 2 with IGMP v2.0 that supports multicast.
3COM 3C1770x (4900 Family):
•
Features Layer 2 non-blocking switch that converts multicast into a broadcast.
Features Layer 2 unmanaged switch that converts multicast into a broadcast.
DGS-3308FG & DGS-3308-TG
Features Layer 3 non-blocking switch that supports multicast.
•
•
Features: Layer 3 switch that supports multicast.

Ethernet to Fiber-Optic Interface Requirements
In cases of camera-to-PC separations of more than 100 meters but an Ethernet switch is not desired, a fiber-optic
media converter can be used. The FlexPoint GX from Omnitron Systems (http://www.omnitron-systems.com/)
converts GigE to fiber transmission and vice versa. It supports multimode (MM) fiber over distances of up to 220 m
(720 ft.) and single-mode (SM) fiber up to 65 km (40 mi.) with SC, MT-RJ, or LC connector types.
Important: The inclusion in this manual of GigE to fiber-optic converters does not guarantee they will meet
specific application requirements or performance. The user must evaluate any supplemental Ethernet equipment.

Installation Issues and Functional Problems
This section covers issues indicated by the GigE server tray icon shows a warning symbol.
GigE Server Warning Example 1a: IP error with multiple NICs
The screenshot below shows an IP conflict error due to two (or more) NICs that are all set to LLA mode. In this
case both NICs are assigned the same IP address preventing communication with any connected Genie.
•
When multiple NICs are used, only one can be set to LLA mode. A second NIC connected to Genie must use
the persistent IP mode or must have a DHCP server on that subnet. The following illustration shows such a
setup.

GigE Server Warning Example 2: Subnet Mask or IP error
The screenshot below shows that the Genie device is not accessible. This IP error is an example of the Genie being
assigned a persistent IP address with an incorrect subnet mask.
•
•
•
•
This example error was made using the DALSA Network Configuration tool, where the Genie was set to
Persistent IP mode with an incorrect subnet mask.
Once the incorrect setting was applied, the Genie was not accessible to the Network Configuration tool or any
application.
The DALSA Network Configuration tool provides a device recovery function to force the Genie back to LLA
An alternative solution is to change IP address of the NIC to match the camera subnet. This might be preferable
if a DHCP server is running on this segment (as the Recovery process requires the NIC to be in LLA mode).
GigE Server Warning Example 3: Filter Driver (CorSnid) Disabled
The screenshot below shows that the Genie device was found but there is an issue with the filter driver (CorSnid).
Such problems occur because the filter driver has become disabled or never installed correctly.
•
Verify that the Filter driver is enabled in the properties for the NIC used with Genie. The screenshot below
shows a typical installation.

Device Available with Operational Issues
This section considers issues with cabling, Ethernet switches, multiple cameras, and camera exposure.
Firmware Updates
As a general rule any Genie installation must include the firmware update procedure (see "Updating Genie
Firmware" on page 27). Genie camera firmware that does not match a newer version of installed Genie Framework
software is likely to have unpredictable behavior. Problems might be:
•
•
Genie is not found by the device discovery process.
Genie is found by the Sapera GigE Server but an application such as CamExpert does not see the camera.
Important: New Genie cameras installed in previously deployed systems are fully backward compatible with the
older vision application. New Genie cameras must not be programmed with older firmware.

Power Failure During a Firmware Update–Now What?
Don't panic! There is far greater chance that the host computer OS is damaged during a power failure than any
permanent problems with the Genie. When electrical power returns and the host computer system has started, the
Genie firmware reprogramming sequence is as follows.
•
•
Connect power to the Genie. The Genie processor knows that the operating firmware is corrupt.
The Genie status LED is slow flashing red. This will continue for about 2 minutes (pre-2007 Genie cameras
may take up to 5 minutes and has no led status).
•
During this period, the Genie is loading embedded write-protected firmware. When the status LED goes blue
the Genie is initialized with a minimal safe boot firmware.
•
•
The Genie is now operating normally as a network device but will not function as a camera.
Perform the firmware update procedure (see "Updating Genie Firmware" on page 27) again. The Genie is now
be ready for use.
Streaming Error: No Acquisition with a Timeout Message
A streaming error is typical with a firewall not allowing the filter driver through. As an example, CamExpert will
run (but start slowly due to initialization timeouts), the Genie is visible in the device pane, but no parameters are
shown to control the camera.
•
If the host computer is using a firewall, either add the GigE Server in the firewall exception list or disable the
firewall completely on the NIC used only with the Genie. Review the following information on disabling
Windows Firewall on the NIC used with Genie.
•
Run the Sapera log viewer program. A firewall block is identified as a timeout event as shown in the following
screen capture (the Genie identifier will match the Genie in use).
Disabling Windows Firewall
Connecting the Genie camera to a system running a firewall would require careful planning of the camera IP and the
ports used by the streaming video and messaging. In general, the Genie camera is installed in a private network or
within a corporate network with an external firewall. In both these cases, the host system that the Genie connects to
does not need to run a firewall, therefore eliminating installation issues.
The Network Configuration tool automatically adds the Sapera GigE Server in the list of Exceptions of the
Windows firewall. Therefore, in most situations, you don’t have to take any special precaution to have the Genie
run through the firewall.
The following figure shows how to turn off the Windows XP firewall when the computer is behind a corporate
network firewall. Run the Windows firewall application from the start menu Start ● Settings ● Control Panel ●
Windows Firewall. If the host computer is running a firewall from a third party, review the program's
documentation to disable its execution.

Turning Windows Firewall Off
With a computer that is not behind a corporate firewall an alternative is to disable Windows firewall only for the
network adapter dedicated for the Genie camera. Such a computer would have two or more network adapters where
one NIC only connects to the Genie—never the Internet.
The following figures show an example of the Windows firewall On but disabled for the network adapter used by
Genie.

Test a Genie Using Internal Test Patterns
The Genie test pattern mode allows quick verification of an installation without the need for correct lighting or lens.
Troubleshooting physical connection issues or communication problems is made easier knowing that the camera can
output a known video signal at selectable frame rates. See "Internal Image Test Patterns" on page 62 for information
on using CamExpert to select internal patterns from Genie.
Cabling and IP Configuration Issues
With only two cables connected to Genie, possible cabling issues are limited.
Power supply problems:
•
If the Genie status LED is off, the DC supply power is not connected or faulty. Verify the power supply voltage
at the Hirose connector. See "12-Pin Hirose Connector Signal Details" on page 90 for pinout information.
Communication problems:
•
Use a shielded cable where the Hirose connector shell electrically connects the Genie chassis to the power
supply earth ground. This can eliminate trigger issues in a high EMI environment.
•
•
•
Check that the Ethernet cable is clipped both to the Genie and the NIC or switch on the other end.
Verify the Ethernet cabling. Poor cables will cause connections to auto-configure at lower speeds.
Use the Genie Ethernet status LED to confirm a gigabit connection. Note that a gigabit connection may still
have many packet resends, rendering the connection useless. This condition has been seen with different NIC
products.
•
•
Use a secured Ethernet cable when the Genie is in a high vibration environment. See "Ruggedized RJ45
Check the Ethernet status LEDs on the Genie RJ45 connector. The network speed indicator should show the
expect connection speed and the activity LED should flash with network messages.
•
•
Verify that the Ethernet cable is CAT5e or CAT6. This is very important with long cable lengths.
When using very long cables, up to the maximum specified length of 100m for gigabit Ethernet, different NIC
hardware and EMI conditions can affect the quality of transmission.

Streaming Video (grab) Issues
Streaming video problems range from total loss of image data to occasional loss of random video data packets. The
following section describes conditions identified by DALSA engineering while working with Genie in various
computers and setups.

Grab Remains Black
While using CamExpert to test a Genie installation, there are no obvious installation problems. But when Grab is
clicked in CamExpert, a grab failure occurs. The grab remains black and an Abort message is displayed.
•
•
•
Typically this problem occurs when the video stream is blocked by a third-party firewall program. Configure
the firewall to pass GigE Vision applications.
Confirm that the problem is the firewall settings and not the Genie sensor by configuring Genie to output its
Computers with VPN software installed most likely need to have the VPN driver disabled in the NIC
properties. This would be required only on the NIC used with the Genie.
Grab has Random Bad Data or Noise
The problem is seen as random noise and missing sections of video data from the acquisition. All configuration
parameters seem correct and the Ethernet cable is secure. The following image shows an example of this type of bad
acquisition while testing a Genie installation with CamExpert (with the Genie set to generate its internal test
pattern).
Following are various examples of this data transmission problem. The solutions vary but commonly involve
reducing the maximum packet size claimed by the NIC used.
Grab has Random Bad Data or Noise – Case 1
•
•
•
This problem has been seen on some computers where the NIC used does not fully support passing the
maximum jumbo frame possible from the Genie.
In the NIC configuration, keep the jumbo frame size set to the maximum allowed. See "Increasing Adapter
Using CamExpert, test for a good acquisition by reducing the Genie packet size used. See "CamExpert GigE
Vision Parameters" on page 65. Also check for packet resend messages with the Sapera tool "Log Viewer".

Grab has Random Bad Data or Noise – Case 2
•
This problem has been seen with network adapters using the Realtek RTL8169 chip and associated low-level
driver. In this case the NIC reports a false maximum jumbo frame size.
•
In the NIC configuration, set the jumbo frame size set to less than the maximum allowed. In this example the
NIC reports supporting a maximum jumbo frame size of 8384 but good acquisitions are possible only when the
size is reduced to 7k. See "Increasing Adapter Buffers and Jumbo Frames" on page 24. and the image below.

•
Using CamExpert, test for a good acquisition by reducing the Genie packet size used. Set the value to the new
Verify there are no packet resend messages with the Sapera tool "Log Viewer".
Grab has Random Bad Data or Noise – Case 3
•
•
•
This problem has also been seen with network adapters that do not support jumbo frames but still report a false
maximum packet frame size.
When using CamExpert, if the Network Configuration Mode is left as Automatic (default), CamExpert uses the
value the NIC reports as its maximum. This maximum value is actually not supported.
Test for a good acquisition by reducing the Genie packet size used. Set the value to a starting value of 1500 to
Laptop Computer Networking Issues
Laptop computers with built in GigE network adapters may still not be able to stream full frame rates from Genie.
Laptops with gigabit Ethernet PCMCIA boards may not be able to stream video at all unless network parameters are
modified. Thorough testing is required with any laptop computer.
Streaming video problems may change depending on the computer chipset and NIC combinations. Laptops running
on battery power may exhibit more bandwidth issues due to the inherent power saving characteristics of laptops.
This section describes a few configuration items to modify for best performance. Verify the Genie at the frame rates
required or to determine the maximum frame rate possible with the laptop used.

Configuration Recommendations with Laptops
•
•
•
In the NIC configuration, keep the jumbo frame size set to the maximum allowed. See "Increasing Adapter
If VPN software is installed, most likely the VPN driver must be disabled in the NIC properties (open via
Control Panel). This would be required only on the NIC used with the Genie.
Run the Sapera Log Viewer: Start•Programs•DALSA•Sapera LT•Tools•Log Viewer. Start the Genie
acquisition program, such as CamExpert. There should not be any "packet resend" messages, else this indicates
problem due to poor connections or extremely high EMI conditions.
•
Packet resends might also be eliminated by adjusting the GigE parameter Inter-Packet Delay. Using CamExpert
(see "CamExpert GigE Vision Parameters" on page 65), increase the inter-packet delay value from 0 to
0.000050 (50µs) and test again.
Problems when Changing the Laptop NIC
If a laptop has had a Genie installed on it and a new NIC is later installed on the laptop, a Genie connected to the
new NIC will not be found. A quick solution is to deselect/reselect the CorSnid driver on that NIC as follows.
•
Open the NIC properties (the one connected to Genie) via Control Panel.
CorSnid Driver Selection
•
•
•
Deselect the CorSnid driver and click the OK button.
Open the NIC properties again and reselect the CorSnid driver.
The Genie will now be found via the automatic device discovery process. This will take a few seconds.

Problems with Disconnecting NICs
Genie cameras installed in environments with physical motion, vibrations, or high EMI may be disconnected by the
NIC. The following items need to be reviewed to solve the problem.
•
•
•
Motion or vibrations may cause data loss because the Ethernet cable connection is not secure. Use a locking
High EMI may cause the NIC to drop data or to disconnect and reconnect at a lower data rate. Such situations
do not have simple solutions and may require an expert consultant.
Some NIC products may not tolerate any data disruptions. Any condition causing the NIC to drop the
connection may make it unrecoverable. Communication with the Genie can not be reestablished without power
cycling. In this case, trying a variety of NIC products is suggested.
Ethernet Switch Issues
An Ethernet switch usually works transparently and presents no problems. Review the following list when
troubleshooting switch issues.
•
•
•
•
•
•
Is the Ethernet switch powered on.
Are all ports used configured as active; not disabled.
Are all ports running at gigabit speeds–not low speed (i.e. not 10 or 100 Mbps).
Is the switch configured to use Jumbo Frames.
Verify the Ethernet cabling. Poor cables will cause connections to auto-configure at lower speeds.
When using a VLAN Ethernet switch, confirm that the Genie and controlling computer are on the same
VLAN group setup on that switch.
•
When using a chain of switches, ensure that inter-switch connection speeds are the same (1000 Mbps).
Multiple Camera Issues
•
When using multiple cameras with a computer with multiple NIC ports, confirm each Genie has been assigned

DALSA provides the Network Configuration tool to verify and configure network devices and the Genie network
parameters. See section "Network Configuration Tool" on page 79 if there were any problems with the automatic
Genie software installation.
VPN Driver Interference
VPN (virtual private network) software using a driver component called "Deterministic Network Enhancement" has
been identified as interfering with the Genie operation when using Framework versions previous to 1.20. At the
