SCXI-1340 Cable Assembly
The SCXI-1340 cable assembly connects an MIO-16 board to an
SCXI-1121 module. The SCXI-1340 consists of a 50-conductor ribbon
cable that has mounting bracket at one end and a 50-pin female connector
at the other end. The female connector connects to the I/O connector of the
MIO-16 board. Attached to the mounting bracket is a 50-pin female
mounting-bracket connector that connects to the module rear signal
connector. To extend the signals of the MIO-16 board to an SCXI-1180
feedthrough panel or an SCXI-1181 breadboard module, you can use the
male breakout connector that is near the mounting bracket on the ribbon
cable. All 50 pins from the MIO-16 board go straight through to the rear
signal connector.
You can use a standard 50-pin ribbon cable instead of the SCXI-1340 cable
assembly. The SCXI-1340 has the following advantages over the ribbon
cable:
•
The SCXI-1340 has strain relief so that you cannot accidentally
disconnect the cable.
•
The SCXI-1340 includes a mounting bracket that mounts to the chassis
so that you can remove and reinsert the module without explicitly
