Programming Devices in Software  
National Instruments measurement devices are packaged with NI-DAQ  
driver software, an extensive library of functions and VIs you can call from  
your application software, such as LabVIEW or LabWindows/CVI, to  
program all the features of your NI measurement devices. Driver software  
has an application programming interface (API), which is a library of VIs,  
functions, classes, attributes, and properties for creating applications for  
your device.  
NI-DAQ 8.x includes two NI-DAQ drivers, Traditional NI-DAQ (Legacy)  
and NI-DAQmx. Each driver has its own API, hardware configuration, and  
software configuration. Refer to the DAQ Getting Started Guide for more  
information about the two drivers.  
Traditional NI-DAQ (Legacy) and NI-DAQmx each include a collection of  
programming examples to help you get started developing an application.  
You can modify example code and save it in an application. You can use  
examples to develop a new application or add example code to an existing  
application.  
To locate LabVIEW and LabWindows/CVI examples, open the National  
Instruments Example Finder:

If you need to clean the DIO device, use a soft, nonmetallic brush. Make  
sure that the DIO device is completely dry and free from contaminants  
before returning it to service.  
Operate the DIO device only at or below Pollution Degree 2. Pollution is  
foreign matter in a solid, liquid, or gaseous state that can reduce dielectric  
strength or surface resistivity. The following is a description of pollution  
degrees:  
Pollution Degree 1 means no pollution or only dry, nonconductive  
pollution occurs. The pollution has no influence.  
Pollution Degree 2 means that only nonconductive pollution occurs in  
most cases. Occasionally, however, a temporary conductivity caused  
by condensation must be expected.  
Pollution Degree 3 means that conductive pollution occurs, or dry,  
nonconductive pollution occurs that becomes conductive due to  
condensation.  
You must insulate signal connections for the maximum voltage for which  
the DIO device is rated. Do not exceed the maximum ratings for the DIO  
device. Do not install wiring while the DIO device is live with electrical  
signals. Do not remove or add connector blocks when power is connected  
to the system. Avoid contact between your body and the connector block  
signal when hot swapping modules. Remove power from signal lines  
before connecting them to or disconnecting them from the DIO device.  
Operate the DIO device at or below the measurement category1 marked  
on the hardware label. Measurement circuits are subjected to working  
voltages2 and transient stresses (overvoltage) from the circuit to which they  
are connected during measurement or test. Installation categories establish  
standard impulse withstand voltage levels that commonly occur in  
electrical distribution systems. The following is a description of installation  
categories:  
Measurement Category I is for measurements performed on circuits  
not directly connected to the electrical distribution system referred to  
as MAINS3 voltage. This category is for measurements of voltages  
from specially protected secondary circuits. Such voltage  
measurements include signal levels, special equipment, limited-energy  
parts of equipment, circuits powered by regulated low-voltage sources,  
and electronics.

Measurement categories, also referred to as installation categories, are defined in electrical safety standard IEC 61010-1.  
Working voltage is the highest rms value of an AC or DC voltage that can occur across any particular insulation.  
MAINS is defined as a hazardous live electrical supply system that powers equipment. Suitably rated measuring circuits may  
be connected to the MAINS for measuring purposes.

Measurement Category II is for measurements performed on circuits  
directly connected to the electrical distribution system. This category  
refers to local-level electrical distribution, such as that provided by a  
standard wall outlet (for example, 115 V for U.S. or 230 V for Europe).  
Examples of Measurement Category II are measurements performed  
on household appliances, portable tools, and similar DIO devices.  
Measurement Category III is for measurements performed in the  
building installation at the distribution level. This category refers to  
measurements on hard-wired equipment such as equipment in fixed  
installations, distribution boards, and circuit breakers. Other examples  
are wiring, including cables, bus-bars, junction boxes, switches,  
socket-outlets in the fixed installation, and stationary motors with  
permanent connections to fixed installations.  
Measurement Category IV is for measurements performed at the  
primary electrical supply installation (<1,000 V). Examples include  
electricity meters and measurements on primary overcurrent  
protection devices and on ripple control units.

Features  
The NI 6509 features digital filtering, programmable power-up states,  
change detection, and a watchdog timer.  
Digital Filtering  
Use the digital filter option available on the NI 6509 input lines to eliminate  
glitches on input data. When used with change detection, filtering can also  
reduce the number of changes to examine and process.  
You can configure the digital input channels to pass through a digital filter,  
and you can control the timing interval the filter uses. The filter blocks  
pulses that are shorter than half of the specified timing interval and passes  
pulses that are longer than the specified interval. Intermediate-length  
pulses—pulses longer than half of the interval but less than the  
interval—may or may not pass the filter.  
Table 1 lists the pulse widths guaranteed to be passed and blocked.  
Table 1. NI 6509 Digital Filtering

Pulse Width Blocked  
Filter Interval  
Low Pulse  
tinterval  
High Pulse  
Low Pulse  
tinterval/2  
High Pulse  
tinterval  
tinterval  
tinterval/2  
You can enable filtering on as many input lines as necessary for your  
application. All filtered lines share the same timing interval, which ranges  
from 400 ns to 200 ms.  
Internally, the filter uses two clocks: the sample clock and the filter clock.  
The sample clock has a 100 ns period. The filter clock is generated by a  
counter and has a period equal to one half of the specified timing interval.  
The input signal is sampled on each rising edge of the sample clock, which  
is every 100 ns. However, a change in the input signal is recognized only  
if it maintains its new state for at least two consecutive rising edges of the  
filter clock.  
The filter clock is programmable and allows you to control how long a  
pulse must last to be recognized. The sample clock provides a fast sample  
rate to ensure that input pulses remain constant between filter clocks.

Figure 2. Digital Filtering Example  
In periods A and B, the filter blocks the glitches because the external signal  
does not remain steadily high from one rising edge of the filter clock to the  
next. In period C, the filter passes the transition because the external signal  
remains steadily high. Depending on when the transition occurs, the filter  
may require up to two filter clocks—one full filter interval—to pass a  
transition. The figure shows a rising (0 to 1) transition. The same filtering  
applies to falling (1 to 0) transitions.  
Programmable Power-Up States  
At power-up, the output drives on the NI 6509 are disabled. All lines are  
user-configurable for high-impedance input, high output, or low output.  
User-configurable power-up states are useful for ensuring that the NI 6509  
powers up in a known state.  
To use MAX (recommended) to program the power-up states, select  
the device and click the Properties button. Refer to the software  
documentation for information about how to program the power-up states  
using NI-DAQ with LabVIEW or other National Instruments application  
development environments (ADEs).  
Note The response time of programmable power-up states is 400 ms.

Change Detection  
You can program the NI 6509 to send an interrupt when a change occurs on  
any input line.  
The NI 6509 can monitor changes on selected input lines or on all input  
lines. It can monitor for rising edges (0 to 1), falling edges (1 to 0), or both.  
When an input change occurs, the NI 6509 generates an interrupt, and the  
NI-DAQ driver then notifies the software.  
Note Excessive change detections can affect system performance. Use digital filtering to  
minimize the effects of noisy input lines.  
The NI 6509 sends a change detection when any one of the changes occurs,  
but it does not report which line changed or if the line was rising or falling.  
After a change, you can read the input lines to determine the current line  
states. The maximum rate of change detection is determined by the  
software response time, which varies from system to system.  
An overflow bit indicates that an additional rising or falling edge has been  
detected before the software could process the previous change.  
Refer to the software documentation for information about how to set up  
and implement the change detection.

This example assumes the following line connections:  
Bits 7, 6, 5, and 4 are connected to data lines from a four-bit TTL  
output device. The NI 6509 detects any change in the input data so  
you can read the new data value.  
Bit 1 is connected to a limit sensor. The NI 6509 detects rising edges  
on the sensor, which correspond to over-limit conditions.  
Bit 0 is connected to a switch. The software can react to any switch  
closure, which is represented by a falling edge. If the switch closure is  
noisy, enable digital filtering for this line.  
In this example, the NI 6509 reports rising edges only on bit 1, falling edges  
only on bit 0, and rising and falling edges on bits 7, 6, 5, and 4. The NI 6509  
reports no changes for bits 3 and 2. After receiving notification of a change,  
you can read the port to determine the current values of all eight lines. You  
cannot read the state of any lines that are configured for change detection  
until the change detection interrupt occurs.  
Watchdog Timer  
The watchdog timer is a software configurable feature used to set critical  
outputs to safe states in the event of a software failure, a system crash, or  
any other loss of communication between the application and the NI 6509.  
When the watchdog timer is enabled, if the NI 6509 does not receive  
a watchdog reset software command within the time specified for the  
watchdog timer, the outputs go to a user-defined safe state and remain in  
that state until the watchdog timer is disarmed by the application and new  
values are written, the NI 6509 is reset, or the computer is restarted. The  
expiration signal that indicates an expired watchdog will continue to assert  
until the watchdog is disarmed. After the watchdog timer expires, the  
NI 6509 ignores any writes until the watchdog timer is disarmed.  
Note When the watchdog timer is enabled and the computer enters a fault condition, ports  
that are set to tri-state remain tri-stated and do not go to user-defined safe states.  
You can set the watchdog timer timeout period to specify the amount of  
time that must elapse before the watchdog timer expires. The counter on the  
watchdog timer is configurable up to (232 – 1) × 100 ns (approximately  
seven minutes) before it expires.

Power Connections  
Pins 49 and 99 supply +5 V power to the I/O connector. The I/O connector  
power has a fuse for overcurrent protection. This fuse is not customer  
replaceable. If the fuse is blown, return the device to NI for repair.  
Caution Do not connect the +5 V power pin directly to ground or to any other voltage  
source on any other device. Doing so may permanently damage the NI 6509 device and the  
computer.  
Signal Connections  
The maximum input logic high and output logic high voltages assume a  
Vcc supply voltage of 5 V. The absolute maximum voltage rating is –0.5 to  
+5.5 V with respect to GND. Refer to the Specifications section for detailed  
information.  
Figure 5 shows an example of signal connections for three typical digital  
I/O applications. Port 0 is configured for digital output, and port 7 is  
configured for digital input. Digital input applications include receiving  
TTL signals and sensing external device states such as the state of the  
switch in the figure. Digital output applications include sending TTL  
signals and driving external devices such as the LED shown in the figure.

Protecting Inductive Loads  
When inductive loads are connected to outputs, a large  
counter-electromotive force may occur at switching time because of the  
energy stored in the inductive load. These flyback voltages can damage  
the outputs and/or the power supply.  
To limit these flyback voltages at the inductive load, install a flyback diode  
across the inductive load. For best results, mount the flyback diode within  
18 inches of the load. Figure 6 shows an example of using an external  
flyback diode to protect inductive loads.
