Getting Started
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.
Figure 1. USB Cable Strain Relief Options
Mounting the NI USB-6509
You can use the NI USB-6509 on a desktop or mount it to a standard DIN
rail or a panel.
Desktop Use
You can use the NI USB-6509 on a desktop. The NI USB-6509 has grooves
on the underside that allow it to be stacked on top of other NI USB-6509
devices.

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.

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
Notes Do not apply the rubber feet to the NI USB-6509 when panel mounting the device.
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.
