Custom Cabling and Connectivity
The CA-1000 is a configurable enclosure that gives user-defined
connectivity and flexibility through customized panelettes. Visit
ni.com
for more information about the CA-1000.
NI offers cables and accessories for many applications. However, if you
want to develop your own cable, 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.
For more information about the connectors used for DAQ devices, refer to
the KnowledgeBase document, Specifications and Manufacturers for
Board Mating Connectors, by going to
