SCXI-1341 Lab-NB, Lab-PC, or Lab-PC+ and SCXI-1344 
Lab-LC Cable Assembly
The SCXI-1341 Lab-NB, Lab-PC, or Lab-PC+ cable assembly connects a 
Lab-NB, Lab-PC, or Lab-PC+ board to an SCXI-1121 module. The 
SCXI-1344 Lab-LC cable assembly connects a Lab-LC board to an 
SCXI-1121 module. The SCXI-1341 and SCXI-1344 cable assemblies 
consist of two pieces—an adapter board and a 50-conductor ribbon cable 
that connects the Lab board to the rear connector of the adapter board. The 
adapter board converts the signals from the Lab board I/O connectors to a 
format compatible with the SCXI-1121 rear signal connector pinout at the 
front connector of the SCXI-1341 or SCXI-1344. The adapter board also 
has an additional male breakout connector that makes the unmodified Lab 
board signals accessible to an SCXI-1180 feedthrough panel or an 
SCXI-1181 breadboard module. The adapter board gives the Lab boards 
full access to the digital control lines and analog signals, 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-1121 does not use
