The 1342 cable assembly consists of two pieces–an adapter board and a 50-conductorribbon cable that connects the PC-LPM-16 board to the adapter board. The adapter boardconverts the signals from the PC-LPM-16 I/O connector to a format compatible with theSCXI-1120 rear signal connector pinout. The adapter board also has an additional male breakoutconnector that makes the unmodified PC-LPM-16 signals accessible to an SCXI-1180feedthrough panel or SCXI-1181 breadboard module. The adapter board gives the PC-LPM-16full access to the digital control lines and analog signals, but the PC-LPM-16 cannot scanchannels in the Multiplexed mode. Leave jumper W1 in position A on the SCXI-1342. TheSCXI-1120 does not use jumper W1. Table E-3 lists the SCXI-1342 pin translations.Table E-3.
