National Instruments NI 783xR C

Using the SCB-68

Shielded Connector Block

This appendix describes how to connect input and output signals to the

NI7 83xR with the SCB-68 shielded connector block.

The SCB-68 has 68 screw terminals for I/O signal connections. To use the

SCB-68 with the NI 783xR, you must configure the SCB-68 as a

general-purpose connector block. Refer to Figure C-1 for the

general-purpose switch configuration.

Figure C-1. General-Purpose Switch Configuration for the SCB-68 Terminal Block

After configuring the SCB-68 switches, you can connect the I/O signals to

the SCB-68 screw terminals. Refer to Appendix B, Connecting I/O Signals,

for the connector pin assignments for the NI 783xR. After connecting

I/O signals to the SCB-68 screw terminals, you can connect the SCB-68 to

the NI7 83xR with the SH68-C68-S shielded cable.
