Custom Cabling and Connectivity

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. To prevent noise when using a cable shield, use separate shields for the analog and
digital sections of the cable.
