Configuration

The NI 6509 device is completely software configurable, so it is not
necessary to set jumpers for I/O configuration.

The PCI-6509 device is fully compliant with the PCI Local Bus
Specification, Revision 2.2, and the PXI-6509 device is fully compliant
with the PXI Hardware Specification, Revision 2.1. The PCI/PXI system
automatically allocates all device resources, including the base address
and interrupt level. The device base address is mapped into PCI memory
space. It is not necessary to perform configuration steps after the system
powers up.

Refer to the application software documentation for configuration
instructions.

After the NI 6509 device and the software are installed, the DAQ device
appears under the Devices and Interfaces branch of the MAX
configuration tree.

If the DAQ device does not appear in MAX, use the following
troubleshooting guidelines.

NI 6509 User Guide and Specifications 4 ni.com

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

Features

Digital Filtering

The NI 6509 features digital filtering, programmable power-up states,
change detection, and a watchdog timer.

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.

Low Pulse High Pulse Low Pulse High Pulse

t

/2 t

interval

/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.

NI 6509 User Guide and Specifications 8 ni.com

Change Detection

Note Excessive change detections can affect system performance. Use digital filtering to

minimize the effects of noisy input lines.

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.

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.

Watchdog Timer

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.

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 (2

32

– 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.
