Using the SCB-68

Shielded Connector Block

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

NI 78xx 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 78xx, you must configure the SCB-68 as a

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

general-purpose switch configuration.

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

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

for the connector pin assignments for the NI 78xx. After connecting

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

SCB-68 to the with the SHC68-68-RMIO (for Connector 0 on the

NI 783x/784x/785x) or SHC68-68-RDIO (Connector <0..3> on the

NI 781x and Connector <1..2> on the NI 783x/784x/785x) shielded cables.
