Custom Cabling and Optional

Connectors

This appendix describes the various cabling and connector options for the
NI 6013/6014.

Custom Cabling

NIoffers cables and accessories for you to prototype your application or to
use ifyo u frequently change deviceinterco nnections.
Ifyou want to develop your own cable, however, adhere to the following
guidelines for best results:
•ForAI signals, use shielded twisted-pair wires for each AI pair for
differentialinputs. Tie the shield for each signal pair to the ground
reference at the source.
•Routethe analoglines separatelyfrom the digital lines.
•When usinga cable shield, use separate shields for the analog and
digital halvesof th ecab le. Failureto do so re sults in noise coupling
into the analog signals from transient digital signals.
Matingconnectors and a backshell kit for making custom 68-pin cables are
availablefrom NI.
Theparts in the following list are recommended for connectors that mate to
the I/O connector on the NI 6013/6014:
•Honda 68-position, solder cup, female connector
•Honda backshell
