NATIONAL INSTRUMENTS @ The Sofrware k the Instrument SCXI-1348 DIO-32F Cable Assembly Installation Guide @ Part Number 320620-01 This guide describes how to install the SCXI-1348 cable assembly between an SCXI module and 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. What Your Kit Should Contain The contents of the SCXI-1348 I Kit Name and Part Number SCXI- 1348 Cable Assembly (776574-48) cable assembly kit are as follows: Component Cable adapter Two small screws 1 m NB4 shielded 50-pin ribbon cable.

Connecting the SCXI-1348 to Your DIO-32F Data Acquisition Board and SCXI Module Perform the following steps to install the SCXI-1348 cable adapter: 1. Turn off the power to your computer and the SCXI chassis. 2. Install your SCXI module in the SCXI chassis, following the instructions in your module user manual. 3. Plug the front connector of the SCXI-1348 into the rear signal connector of the SCXI module. A comer of the adapter board will enter the upper board guide of the chassis. 4. Secure the SCXI-1348 adapter board by screwing the two screws through the rear panel of the adapter board and into the threaded strips in the rear of the SCXI chassis. 5. Connect one end of the 50-pin shielded ribbon cable to the adapter board rear connector. 6. Install your data acquisition board in a slot in your computer, following the instructions in your data acquisition board user manual. 7. Connect the loose end of the shielded ribbon cable to the I/O connector on the data acquisition board as shown in Figure 2.
