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
National Instruments 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, use the following
guidelines:
• For the analog input signals, shielded twisted-pair wires for each
analog input pair yield the best results, assuming that you use
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 parts of the cable. Failure to do so results in noise coupling into
the analog signals from transient digital signals.
The following list gives recommended connectors that mate to the I/O
connector on your device.
