Lab boards full access to the digital control lines and analog signals (except DTEMP), but the Lab
boards cannot scan channels in Multiplexed mode. Leave jumper W1 in position A on the
SCXI-1341 and SCXI-1344. The SCXI-1120 does not use jumper W1. Table E-2 lists the
SCXI-1341 and SCXI-1344 pin translations.
Note: If you are using the Lab-PC+, configure the board for single-ended inputs.
