National Instruments NI 1410 A

Custom Cables

This appendix lists specifications for building custom cables to use with the

NIPCI-14 10 device.

Cable Specification

National Instruments offers cables and accessories for you to connect to

video sources, trigger sources, or synchronization sources. Use the

following guidelines when developing your own cables:

• For the video inputs, use a 75 Ω shielded coaxial cable.

• For the digital triggers and synchronization signals, use twisted pairs

foreach signal.

For information about connector pin assignments, refer to the Digital I/O

Connector section of Chapter3, Signal Connections .

Connector Specifications

• Video and sync signals—75 Ω impedance

• Trigger signals—TTL

• Type—75 Ω BNC or 68-pin VHDCI receptacle
