Getting Started with the NI PCIe-8253
Note
Check that the bracket of your device aligns with the hole in the back panel rail of the
computer chassis.
7.
Secure the device mounting bracket to the back panel rail of the computer.
8.
To provide auxiliary power for your cameras, connect an unused power connector from the ATX
power supply on your computer to the camera power ATX connector on your NI 8253.
9.
Replace the computer cover.
10. Connect the IEEE 1394 cable to the camera. Refer to your camera manufacturer documentation for
specific instructions about how to connect the cable to your camera.
11. Connect the IEEE 1394 cable to the IEEE 1394 connector on the NI 8253 front panel.
12. Plug in and power on the computer.
The NI 8253 is now installed, and the camera is connected.
Configuring the NI 8253
After you have installed the NI 8253 and powered on the computer, the computer will recognize the
device and assign resources to it. Use Measurement & Automation Explorer (MAX), the National
Instruments configuration utility, to configure the NI 8253 for acquisition. Refer to the
Measurement &
Automation Explorer Help for NI-IMAQdx
for additional information about configuring the NI 8253.
Note
Before configuring the device in MAX, ensure that you installed the NI-IMAQdx driver
software.

1
The bus power specification assumes that power is provided to the NI 8253 device from the host computer power supply using
the ATX power connector. If power is not supplied through the ATX power connector, camera power is supplied by the PCIe
bus and should be limited to 9 W, shared by all ports.

To connect an IEEE 1394a camera to the NI 8253, you will need a 6-pin to 9-pin cable or a 6-pin to 9-pin adapter.
