Perform the following steps to install the SCXI-1342 cable:
1. Turn off the power to your computer and the SCXI chassis.
2. Install your SCXI module in the SCXI chassis, following the instructions in your module
user manual.
3. Set jumper W1 on the SCXI-1342 adapter board to the correct position for your system, as
shown in Figure 2. When set to position A, the factory-default position, jumper W1 connects
pin 46 of the PC-LPM-16 to pin 46 of the module connector. Position B breaks this
connection. Leave jumper W1 in position A unless you are using an SCXI-1140 module and
are not supplying the HOLDTRIG signal to the module from the PC-LPM-16. See your
SCXI-1140 User Manual
for an explanation of the HOLDTRIG signal.
