SCXI-1342 PC-LPM-16 Cable Assembly
The SCXI-1342 PC-LPM-16 cable assembly connects a PC-LPM-16 board to an SCXI-1120
module. The 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-1120 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 SCXI-1181 breadboard module. The adapter board gives the PC-LPM-16
full access to the digital control lines and analog signals, but the PC-LPM-16 cannot scan
channels in the Multiplexed mode. Leave jumper W1 in position A on the SCXI-1342. The
SCXI-1120 does not use jumper W1. Table E-3 lists the SCXI-1342 pin translations.
