NI USB-6509 devices feature up to 96 bidirectional per-port static DIO
lines. If you have not already installed your device, refer to the NI-DAQmx
for USB Devices Getting Started Guide.
Before installing your DAQ device, you must install the software you plan
to use with the device.
Installing Software
Software support for the NI USB-6509 for Windows is provided by
NI-DAQmx.
The NI-DAQmx CD contains example programs that you can use to get
started programming with the NI USB-6509. Refer to the NI-DAQmx for
USB Devices Getting Started Guide, that shipped with your device and
is also accessible from Start»All Programs»National Instruments»
NI-DAQ, for more information.
Note For information about non-Windows operating system support, refer to
ni.com/info and enter rddqld.

Installing the Hardware
The NI-DAQmx for USB Devices Getting Started Guide contains
non-software-specific information about how to install USB devices.
USB Cable Strain Relief
The two strain relief options for your USB cable are as follows:
• Cable Strain Relief Groove Method—Press the USB cable into one
of the two grooves on the underside of the NI USB-6509. Choose the
USB cable groove that matches your USB cable size, as shown in
Figure 1.
• Zip Tie Method—Thread a zip tie through the zip tie bar on the
underside of the NI USB-6509 and tighten around the USB cable,
as shown in Figure 1.

For secure desktop use, you can adhere the supplied rubber non-skid feet to
the underside of the device, as shown in Figure 2.
Note Do not apply the rubber feet if you are panel mounting the NI USB-6509 or stacking
multiple NI USB-6509 devices.
Figure 2. Applying Rubber Feet to the NI USB-6509
DIN Rail Mounting
The DIN rail mounting kit (part number 779689-01, not included in your
NI USB-6509 kit) is an accessory you can use to mount the NI USB-6509
to a standard DIN rail.
Note Apply strain relief, as described in the USB Cable Strain Relief section, before
mounting the NI USB-6509 to a DIN rail.
NI 6509 User Guide and Specifications 4 ni.com
Panel Mounting
To mount the NI USB-6509 to a board or panel, complete the following
steps while referring to Figure 3.
Figure 3. Mounting the NI USB-6509 on a Panel
Do not apply the rubber feet to the NI USB-6509 when panel mounting the device.
Notes
Apply strain relief, as described in the USB Cable Strain Relief section, before panel
mounting the NI USB-6509.
1. Go to ni.com/info and enter the info code rd3233 to download and
print the panel mounting template PDF.
2. Using the template, mark the bottom point and top point on the panel.
The points will be 162 mm (6.375 in.) from each other.
3. Remove the USB cable from the connector on the NI USB-6509.
4. Screw a #8 or M4 screw into the bottom point on the panel.
5. Set the NI USB-6509 on the screw by fitting it into the bottom screw
notch on the underside of the NI USB-6509.
6. Screw a #8 or M4 screw through the NI USB-6509 top screw hole into
the panel.

Programming Devices in Software
National Instruments measurement devices for USB 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
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 NI-DAQmx, which has its own API, hardware
configuration, and software configuration. Refer to the NI-DAQmx for USB
Getting Started Guide for more information.
NI-DAQmx includes 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:
• In LabVIEW, select Help»Find Examples.
• In LabWindows/CVI, select Help»NI Example Finder.
Measurement Studio, Visual Basic, and ANSI C examples are in the
following directories:
• NI-DAQmx examples for Measurement Studio-supported languages
are in the following directories:
–
– MeasurementStudio\DotNET\Examples\NIDaq
• NI-DAQmx examples for ANSI C are in the NI-DAQ\Examples\
DAQmx ANSI C Dev directory
™
/CVI™, to program all the features of your NI measurement
MeasurementStudio\VCNET\Examples\NIDaq

I/O Connector
The 100-pin high-density SCSI connector on the NI USB-6509 provides
access to 96 digital inputs and outputs. Use this connector to connect to
external devices, such as solid-state relays (SSRs) and LEDs. For easy
connection to the digital I/O connector, use the National Instruments
SH100-100-F shielded digital I/O cable with the SCB-100 connector block,
or use the R1005050 ribbon cable with the CB-50 or CB-50LP connector
block.
Caution Do not make connections to the digital I/O that exceed the maximum I/O
specifications. Doing so may permanently damage the NI USB-6509 device and the
computer. Refer to the Signal Descriptions and Specifications sections for information
about maximum input ratings.
Pin Assignments
SH100-100-F Pin Assignments
Figure 6 shows the pin assignments for the NI USB-6509 using the
SH100-100-F cable. The naming convention for each pin is PX.Y, where X
is the port (P) number, and Y is the line number or name.
