Custom Cabling and Optional
Connectors
This appendix describes the various cabling and connector options for the
NI 6013/6014.
Custom Cabling
NI offers cables and accessories for you to prototype your application or to
use if you frequently change device interconnections.
If you want to develop your own cable, however, adhere to the following
guidelines for best results:
• For AI signals, use shielded twisted-pair wires for each AI pair for
differential inputs. Tie the shield for each signal pair to the ground
reference at the source.
• Route the analog lines separately from the digital lines.
• When using a cable shield, use separate shields for the analog and
digital halves of the cable. Failure to do so results in noise coupling
into the analog signals from transient digital signals.
Mating connectors and a backshell kit for making custom 68-pin cables are
available from NI.
The parts 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
Optional Connectors
Figure B-1 shows the pin assignments for the 68-pin connector.
This connector is available when you use the SH6868 or R6868 cable
assemblies.
