Step 2. Assemble Your SCXI System

A.  Configure the SCXI-1102 Module and Terminal Block—Most configuration

settings of the SCXI-1102 are set via software. The SCXI-1102 does include

one jumper, W1, which you should leave in the factory-default position

(position P). You do not need to modify the setting of W1 jumper unless you

are daisy-chaining multiple SCXI chassis and a cable is attached directly to

the SCXI-1102.

Note:

The SCXI-1300 and SCXI-1303 include a jumper to select the MTEMP or DTEMP channel

for the cold-junction sensor input. When used with the SCXI-1102, the position of this

jumper is irrelevant; MTEMP and DTEMP are connected internally in the SCXI-1102.

B.

Insert the SCXI-1102 module into your SCXI chassis.

C.  Cable SCXI module to your DAQ board—If you are using a plug-in DAQ

board, connect the SCXI-1102 to your DAQ board using the appropriate

SCXI-134X cable assembly.

If you are using the SCXI-1200 module, install the module into your SCXI

chassis and connect the SCXI-1200 to the parallel port of your PC, using the

cable included in the SCXI-1200 kit.

D.

Attach terminal block—Finally, plug the SCXI-1300 or SCXI-1303 terminal

block onto the front of the SCXI-1102 module.
