NI offers a variety of cables for connecting signals to the NI 781xR. If you 
need to develop a custom cable, a generic unterminated shielded cable is 
available from NI. The SHC68-NT-S connects to the NI 781xR VHDCI 
connectors on one end of the cable. The other end of the cable is not 
terminated. This cable ships with a wire list identifying which wire 
corresponds to each NI 781xR pin. Using this cable, you can quickly 
connect the NI 781xR signals that you need to the connector of your choice. 
Refer to Appendix B, 

, for the NI 781xR connector 

pinouts.
