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.

3
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,
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.

Pulse Width Passed
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.

NI 6509 User Guide and Specifications
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
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.
