Custom Cabling
NI offers cables and accessories for many applications. However, if you
want to develop your own cable, the following kits can assist you:
•
TB-37F-37SC—37-pin solder cup terminals, shell with strain relief
•
TB-37F-37CP—37-pin crimp & poke terminals, shell with strain
relief
Also, adhere to the following guidelines for best results:
•
For AI signals, use shielded, twisted-pair wires for each AI pair of
differential inputs. Connect 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 sections of the cable. Failure to do so results in noise coupling
into the analog signals from transient digital signals.
