This section contains important safety information that you must follow when installing and
using National Instruments DIO devices.
Do not operate the device in a manner not specified in this document. Misuse of the DIO device
can result in a hazard. You can compromise the safety protection built into the DIO device if it
is damaged in any way. If the DIO device is damaged, return it to NI for repair.
Do not substitute parts or modify the DIO device except as described in this document. Use the
DIO device only with the chassis, modules, accessories, and cables specified in the installation
instructions. You must have all covers and filler panels installed during operation of the DIO
device.
Do not operate the DIO device in an explosive atmosphere or where there may be flammable
gases or fumes.
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

Measurement circuits are subjected to working voltages
and transient stresses (overvoltage)
marked on the hardware label.
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 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.

Digital I/O
Static DIO on NI 6509 Devices
The NI 6509 device provides 96 lines of bi-directional DIO signals, P<0..11>.<0..7>. You can
use each of the NI 6509 DIO lines as a static digital input (DI) or digital output (DO) line. You
can use static DIO lines to monitor or control digital signals. With the PCI/PXI-6509, each DIO
port can be configured as a DI or DO port. The PCIe-6509 can be configured on a line by line
basis. All samples of DI lines and updates of DO lines are software-timed.
I/O Protection
Use the following guidelines to avoid electrostatic discharge (ESD) events and fault conditions
such as overvoltage, undervoltage, and overcurrent:
• If you configure a DIO line as an output, do not connect the line to any external signal
source, ground signal, or power supply.
• If you configure a DIO line as an output, understand the current requirements of the load.
Do not exceed the output limits of the DAQ device. NI has several signal conditioning
solutions for digital applications that require high current drive.
• If you configure a DIO line as an input, do not drive the line with voltages outside of the
normal operating range.
• Do not drive the line when the device/system is powered off. Doing so could result in
unexpected behavior. Note that the PCIe-6509 Rev C (or later) has protection circuitry in
place to protect against possible unexpected behavior when driving the line under power
off conditions.
• Treat the DAQ device as you would treat any static sensitive device. Always properly
ground yourself and the equipment when handling the DAQ device or connecting to it.
I/O Pull-Up/Pull-Down Resistors (PCIe-6509 Only)
The PCIe-6509 has user-configurable pull-up and pull-down resistors. The DIO lines on the
PCIe-6509 are connected to an NI ASIC that contains a weak pull-down resistor (47 k,
typical), and each DIO line is connected to a software-selectable strong pull-up resistor (4.7 k,
typical), as Figure 5 shows.

Digital I/O Line
If you set the software to pull-down, the weak pull-down resistor in the NI ASIC pulls the DIO
line low. If you set the software to pull-up, the strong pull-up resistor pulls the DIO line high.
The pull setting takes effect regardless of the I/O direction, but the pull setting affects only the
state of the DIO lines that are configured for input.
To use MAX to configure the I/O pull resistor, select the device and click the Properties button.
Refer to the software documentation for information about how to program the pull setting using
NI-DAQmx with LabVIEW or other NI application development environments (ADEs).
Signal Connections
Figure 6 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 output applications include sending TTL signals and driving external devices such as the
LED shown in the figure. Digital input applications include receiving TTL signals and sensing
external device states such as the state of the switch in the figure.
Protecting Inductive Loads
When inductive loads are connected to output lines, 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 7 shows an
example of using an external flyback diode to protect inductive loads.

Power Connections
+5 V Power Available at I/O Connector
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.
Disk Drive Power Connector (PCIe-6509 Only)
The disk drive power connector is a four-pin hard drive connector on the PCIe-6509 that, when
connected, increases the current the device can supply on the +5 V terminal.
Note The disk drive power has a fuse for overcurrent protection. This fuse is not
customer replaceable. If the fuse is blown, the fuse LED (reference designator
DS1—located on the visible edge of the underside of the installed device) is lit. In
this case, return the device to NI for repair.

You can install the disk drive power connector if you want to increase the power supply on the
+5 V terminal. However, it is not necessary to install the disk drive power connector for most
applications.
Refer to the Specifications section for more information about the power requirements and
power limits of the PCIe-6509.
Disk Drive Power Connector Installation
Before installing the disk drive power connector, you must install and set up the PCIe-6509 as
described in the DAQ Getting Started guides. Complete the following steps to install the disk
drive power connector:
1. Power off and unplug the computer.
2. Remove the computer cover.
3. Attach the PC disk drive power connector to the disk drive power connector on the
PCIe-6509, as Figure 13 shows.
Figure 13. Connecting to the Disk Drive Power Connector
1 Device Disk Drive Power Connector 2 PC Disk Drive Power Connector
Note The power available on the disk drive power connectors in a computer can
vary. For example, consider using a disk drive power connector that is not in the same
power chain as the hard drive.
4. Replace the computer cover, and plug in and power on the computer.
Industrial DIO Features
The NI 6509 features digital filtering, programmable power-up states, change detection, and a
watchdog timer.
Digital Filtering
You can use the digital filtering option available on the NI 6509 to eliminate glitches on input
data. When used with change detection, digital filtering can also reduce the number of changes
to examine and process.
16 | ni.com | PCI/PXI/PCIe-6509 User Guide and Specifications

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 2 lists the pulse widths that the NI 6509 is certain to pass and block.

You can enable digital 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 on the NI
PCI/PXI-6509. The PCIe-6509 supports only three timing intervals: 160 ns, 10.24 s, and
5.12 ms.
Internally, the digital filter uses two clocks: a sample clock and a filter clock. The filter clock is
generated by a counter and has a period equal to one half of the specified timing interval. The
NI 6509 samples the input signal on each rising edge of the sample clock, but the NI 6509
recognizes a change in the input signal only if the input signal 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 by the NI 6509.
Digital Filtering Example
Figure 14 shows an example of digital filtering.
Figure 14. 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.
PCI/PXI/PCIe-6509 User Guide and Specifications | © National Instruments | 17
Page 18
The figure shows a rising (0 to 1) transition. The same filtering applies to falling (1 to 0)
transitions.
Programmable Power-Up States
You can program the DIO lines on the NI 6509 to power up at a predefined state: input, high
output, or low output. Programmable power-up states ensure that the NI 6509 powers up in a
known state.
Note On the PCIe-6509, the DIO lines can be pulled high or low. For more
information, refer to the I/O Pull-Up/Pull-Down Resistors (PCIe-6509 Only) section.
The typical response time of programmable power-up states is 400 ms for the PCI/PXI-6509 and
500 ms for the PCIe-6509.
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-DAQmx with LabVIEW or other NI application development
environments (ADEs).
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 notifies the software.
However, the NI 6509 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 rate of
change detection is determined by the software response time, which varies from system to
system.
Note Excessive change detections may affect system performance. Use digital
filtering to minimize the effects of noisy input lines.
An overflow bit indicates that the NI 6509 detects an additional rising or falling edge before the
software processes the previous change.
Refer to the software documentation for information about how to set up and implement the
change detection feature.

Change Detection Example
Table 3 shows a change detection example for six bits of one port.
Table 3. Change Detection Example
Bit
7 6 5 4 3 2 1 0
Changes to detect — —
Enable rising-edge
detection
Enable falling-edge
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 NI 6509 reacts 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 on only bit 1, falling edges on only 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. However, you cannot read the lines that are configured for change detection until
a change detection interrupt occurs.

Watchdog Timer
The watchdog timer is a software-configurable feature that sets critical output lines to predefined
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.
After you enable the watchdog timer, if the NI 6509 does not receive a watchdog reset software
command within the time specified for the watchdog timer, the output lines enter a user-defined
safe state and remain in that state until one of the following events occurs:
• The application disarms the watchdog timer and writes new values to the output lines.
• The NI 6509 is reset.
• The computer is restarted.
PCI/PXI/PCIe-6509 User Guide and Specifications | © National Instruments | 19
Page 20
The signal indicating an expired watchdog asserts continuously until the application disarms the
watchdog timer. After the watchdog timer expires, the NI 6509 ignores any writes until the
application disarms the watchdog timer.
Note On the PCIe-6509, ports that are set to tristate cannot enter safe states of
output when the computer enters a fault condition.
You can set the watchdog timer timeout period to specify the amount of time that elapses before
the watchdog timer expires. The counter on the watchdog timer is configurable up to (232 – 1)
32
100 ns (about seven minutes) on the PCI/PXI-6509 and (2
– 1) 32 ns (about two minutes) on
the PCIe-6509 before the watchdog timer expires.
