DVI KVM over IP  
Operating Notes  
•
The DVI KVM over IP is compatible with the HD KVM over IP and the VGA KVM over  
IP, which allows these products to be connected within a single system. Note that  
HDCP content cannot be used when using these products in tandem.  
•
CAT-5 or CAT-6 cables should not exceed 330 feet (100 meters) between the  
Sender / Receiver unit and the network.  
•
•
•
By default, all Sender and Receiver units are set to channel 0.  
This product does not support HDCP or dual link resolutions.  
By default, the source device will use the EDID from the display (or other sink device)  
which is connected the Receiver unit. See EDID Management for more information.  
•
If terminating network cables in the field, please adhere to the TIA/EIA568B  
specification. See the Network Cable Diagram for details.  
IMPORTANT: The use of a Gigabit switch with 8K “jumbo frame”  
capability is required when connecting the DVI KVM over IP to a  
network.

Getting Started  
Installation  
The DVI KVM over IP Sender and Receiver units can either be connected over a Local  
Area Network (LAN) or they can be directly connected to one another.  
Using a Direct Connection  
By default, the DVI KVM over IP is shipped in Auto IP mode. In Auto IP mode, each  
Sender and Receiver unit assigns itself a unique IP address within the range of  
169.254.x.x. Auto IP mode is only used when Sender and Receiver units are directly  
connected to one another. When connecting to a network, the DVI KVM over IP must be  
set to DHCP mode or Static IP mode. See Setting the IP Mode for more information.  
1. Connect a CAT-5e (or better) cable from the LAN port on the Sender unit to the  
LAN 1 port on the Receiver unit.  
Figure 1.1 - Directly connecting the Sender and Receiver unit  
Sender unit  
CAT-5e cable (or better)

Connect to other  
Receivers / IP devices  
Although any LAN port on the Receiver unit can be used, using the LAN 1 port makes  
it easy to identify which Ethernet cable is used to connect the Sender and Receiver  
unit. LAN 2 and LAN 3 ports can then be used for connecting additional devices or  
when daisy-chaining Receiver units.  
2. Use the included DVI cable to connect the DVI source to the DVI In port on the  
Sender unit.  
3. Connect a DVI cable from the DVI display to the DVI Out port on the Receiver unit.

Local Area Network (LAN) Connection  
IMPORTANT: The use of a Gigabit switch with 8K “jumbo frame”  
capability is required when connecting the DVI KVM over IP to a  
network.  
In order to connect the DVI KVM over IP to a Local Area Network (LAN), both the Sender  
and Receiver unit must first be set to DHCP mode or static IP mode. DHCP mode will use  
the DHCP server to automatically assign an IP address for each Sender and Receiver unit  
that is connected to the network. Static IP mode will allow the IP address for each Sender  
and Receiver unit to be configured manually. Contact your network administrator if  
necessary.  
1. Follow the connection steps under Using a Direct Connection.  
2. Connect an Ethernet cable from one of the LAN ports on the Receiver unit to the  
network.  
If DHCP mode will be used, connect the Receiver unit to a DHCP server.

Unicast and Multicast Modes  
Configuring Unicast Mode  
The term unicast is used to describe a configuration where information is sent from one  
point to another point. It is possible to have multiple Sender and Receiver units connected  
in a system. However, in unicast mode a Sender unit can communicate with only one  
Receiver unit at a time. In unicast mode, the DVI KVM over IP functions similiar to a DVI  
KVM switcher.  
NOTE: The DVI KVM over IP Sender and Receiver units shipped  
from the factory in unicast mode.  
The illustration, below, shows 3 Sender units (S1, S2, and S3) and 2 Receiver units  
(R1 and R2) on a network, operating in unicast mode. The video channels are notated  
in blue.

Switching between Sender units in Unicast mode  
When multiple Sender and Receiver unit are used in unicast mode, the DVI KVM over IP  
behaves as a switcher. In unicast mode, a Sender unit can communicate with only one  
Receiver unit at a time.  
In the example below, we will switch Receiver unit R1 to receive the DVI source on Sender

Operating the DVI KVM over IP  
Unicast and Multicast Modes  
In order to solve the problem, in Figure 2.4, we would need to make sure that each of  
the Sender units is set to a unique channel number.  
When using unicast mode, each of the Sender units must be assigned a unique  
channel and should never be changed. Use the Receiver unit to switch (channels)  
between Sender units.  
The DVI KVM over IP can be used with up to 256 Sender units to provide switching  
capability between each Receiver unit. Up to 256 Receiver units are supported.  
Each Receiver unit can be set to receive video data from any one of 256 Sender units.  
NOTE: In unicast mode, if an additional Sender unit is introduced  
into a system with the same channel as another Sender unit, then  
the Receiver unit will continue to receive A/V data from the Sender  
unit which was connected first.

Configuring Multicast Mode  
The term multicast is used to describe a configuration where information is sent from one or  
more points to a set of other points. For example, a single Sender unit can transmit data to  
multiple Receiver units. In addition, if multiple Sender units are used, each Sender unit can  
transmit data to any Receiver that is not already receiving data from another Sender unit.  
In multicast mode, the DVI KVM over IP functions similar to a DVI KVM matrix.  
The illustration, below, shows 3 Sender units (S1, S2, and S3) and 2 Receiver units  
(R1 and R2) on a network, operating in multicast mode. The video channels are shown  
in blue.

Operating the DVI KVM over IP  
Using RS-232  
The DVI KVM over IP supports RS-232 pass-through, allowing the control of remote  
RS-232 devices. The Sender and Receiver unit which are being used to pass-through  
the RS-232 data must be set to the same baud rate as the RS-232 host and client.  
In the example below, the Gefen 4x1 DVI Switcher w/ Audio Decoding (Gefen part no.  
GTV-AUDDEC-N) has been connected to Receiver unit A. This is the RS-232 client.  
We want to control this product from Sender unit S3, using a laptop PC (RS-232 host).

Operating the DVI KVM over IP  
EDID Management  
The DVI KVM over IP features EDID Management. Before the source can send video  
(and/or audio) data, the source device (connected to each Sender unit) reads the EDID  
(Extended Display Identification Data) from the displays which are connected to each  
Receiver unit. The EDID contains information about what type of audio/video data can  
be sent by each source.  
By default, the (downstream) EDID from the display, connected to the Receiver unit, is  
used. However, under certain circumstances, it may be desirable to use the internal EDID  
which is stored in the Sender unit.  
Using the Internal DVI EDID  
1. Access the Web interface for the Sender unit.  
2. Click the Functions tab.  
3. Click the Load Internal EDID button.  
4. After a few moments, the following message will appear at the top of the page,

Audio Connections  
Audio works in both unicast and multicast modes. The only difference between the two  
modes is that the Mic In jack is automatically disabled, on all Receiver units, in multicast  
mode. To illustrate how audio works with the DVI KVM over IP, we will set up a microphone  
and some speakers.  
1. Our computer has a Line In jack, as part of the sound card and we want to be able to  
access this jack from the Receiver unit. Therefore, connect the microphone to the  
Mic In jack on the Receiver unit.  
Connect to microphone  
2. In order to get the audio from the microphone into the computer, connect a  
3.5mm-to-3.5mm mini-stereo cable from the Line Out jack on the Sender unit to  
the Line In jack on the computer.  
WARNING: Do not connect the mini-stereo cable from the Line  
Out jack on the Sender unit to the Mic In jack on the computer.  
Doing so will result in audio “clipping” and may cause damage to  
the computer’s sound card.

Using HDMI Sources  
Hi-Def (HDMI) sources can be connected to the DVI KVM over IP when using HDMI-to-DVI  
adapters on the Sender and Receiver units. HDMI audio is passed through to the DVI Out  
port on the Receiver unit. The DVI KVM over IP will not pass content from HDCP sources  
such as Blu-ray players and Playstation® console systems.  
If a 3.5mm mini-stereo cable is connected to the Line In jack on the Sender unit, then the  
HDMI audio will be disabled on the Receiver unit. The Line Out jack, on the Receiver unit,  
will output audio from the source connected to the Line In jack on the Sender unit.  
HDMI audio cannot be output using the Line Out jack on the Receiver unit.
