Installation Guide
Part Number 320620-01
This guide describes how to install the SCXI-1348 cable assembly between an SCXI module and I
an AT-DIO-32F, MC-DIO-32F, or NB-DIO-32F data acquisition board. In addition to the
SCXI-1348 kit contents, you will also need an SCXI chassis, an SCXI module, a computer, a
DIO-32F data acquisition board, and a small flathead screwdriver.
Introduction
With the SCXI-1348 cable assembly, you can connect a digital I/O SCXI module to your
DIO-32F data acquisition board. The DIO-32F works with the SCXI-1160, SCXI-1161,
SCXI- 1162, and SCXI- 1163 modules.
If you have a newly released module or a data acquisition board other than a DIO-32F, contact
National Instruments for information on your cable needs.
The SCXI-1348 cable assembly consists of an adapter board and an NB4 50-conductor shielded
ribbon cable that connects the adapter board to a DIO-32F data acquisition board. The adapter
board converts the signals from the DIO-32F I/O connector to the pinout that a digital SCXI
module rear signal connector uses. To extend the unconverted signals of the DIO-32F to another
module or to an SCXI-1180 feedthrough panel, you can use the male breakout connector that is
on the center of the adapter board.

Perform thefollowing stepsto install theSCXI-1348 cableadapter:
1. Turn off the power to your computer andtheSCXI chassis.
2. Install your SCXI module in the SCXI chassis,following the instructions in your module
usermanual.
3. Plug thefront connector of theSCXI-1348 into therearsignal connector of the SCXI
module. A comer of the adapterboardwill entertheupperboard guide of the chassis.
4. Securethe SCXI-1348 adapterboardby screwing the two screws through therearpanel of
theadapterboard andinto the threadedstrips in therearof the SCXI chassis.
5. Connect oneendof the 50-pin shielded ribbon cable to the adapterboard rearconnector.
6. Install your dataacquisition boardin aslot in your computer, following theinstructions in
your dataacquisition boardusermanual.
7. Connect the looseend of theshielded ribbon cable to theI/O connector onthe data
acquisition board asshown in Figure 2.
