Custom Cabling and Optional

Connectors

This appendix describes the various cabling and connector options for the
DAQCard-6024E,PCI-6023E, PCI-6024E, PCI-6025E, and PXI-6025E
devices.

Custom Cabling

NationalI nstrumentsoffers cablesand accessories for you to prototype
yourapplication or to use if you frequently chan ge device interconnections.
Ifyou want to develop your own cable, however, use the following
guidelines:
•Forthe analog input signals, shielded twisted-pair wires for each
analog inputpair y ield theb estresults, assuming that you use
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
digitalparts of the cable. Failure to do so re sults in noise coupling into
the analog signals from transient digital signals.
The followinglist gives recommended connectors that mate to the I/O
connector on your device.
