1.
Make sure that the computer and the SCXI chassis are turned off.
2.
Install the SCXI module in the chassis.
3.
Connect one end of the ribbon cable to the adapter board rear
connector. This is the 50-pin connector of the SCXI-1344 cable.
4.
Plug the adapter board front connector to the module rear signal
connector. Make sure a corner of the adapter board enters the upper
board guide of the chassis.
5.

6.
For an SCXI-1341, connect the loose end of the ribbon cable to the
Lab-NB, Lab-PC, or Lab-PC+ I/O connector. For an SCXI-1344,
connect the two 26-pin connectors to the Lab-LC according to the
instructions given in the

SCXI-1342 PC-LPM-16 Cable Assembly
The SCXI-1342 PC-LPM-16 cable assembly connects a PC-LPM-16 board
to an SCXI-1121 module. The SCXI-1342 cable assembly consists of
two pieces—an adapter board and a 50-conductor ribbon cable that
connects the PC-LPM-16 board to the adapter board. The adapter board
converts the signals from the PC-LPM-16 I/O connector to a format
compatible with the SCXI-1121 rear signal connector pinout. The adapter
board also has an additional male breakout connector that makes the
unmodified PC-LPM-16 signals accessible to an SCXI-1180 feedthrough
panel or an SCXI-1181 breadboard module. The adapter board gives the
PC-LPM-16 full access to the digital control lines and analog signals, but
