Cables and Accessories (NI 6122/6123)

This section describes some of the cable and accessory options for the NI 6122/6123. For more specific information about these products, refer to ni.com.

Using BNCs

You can connect BNC cables to your DAQ device using BNC accessories such as the BNC-2110, BNC-2120, and BNC-2090. To connect your DAQ device to a BNC accessory, use one of the following cables:

  • SH68-68-EP—shielded 68-conductor cable
  • SH68-68R1-EP—shielded right-angle 68-conductor cable
  • SH6868—shielded 68-conductor cable
  • R6868—68-conductor ribbon cable

Using Screw Terminals

You can connect signals to your DAQ device using a screw terminal accessory such as:

  • CB-68LP, CB-68LPR—low-cost screw terminal block
  • SCB-68—shielded screw terminal block with breadboard areas
  • TBX-68—DIN rail mountable screw terminal block

To connect your DAQ device to a screw terminal accessory, use one of the following cables:

  • SH68-68-EP—shielded 68-conductor cable
  • SH68-68R1-EP—shielded right-angle 68-conductor cable
  • SH6868—shielded 68-conductor cable
  • R6868—68-conductor ribbon cable

Using RTSI

Use RTSI bus cables to connect the timing and synchronization signals on your DAQ device to other Measurement, Vision, Motion, and CAN boards for PCI.

Custom Cabling/Connectors Options

The CA-1000 is a versatile connector/enclosure system. It allows the user to define I/O connectors on a per-channel basis. Internally, the system allows for flexible custom wiring configuration.

If you want to develop your own cable, follow these guidelines for best results:

  • Use shielded twisted-pair wires for each differential AI pair. 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 halves of the cable. Failure to do so results in noise coupling into the analog signals from transient digital signals.

Mating connectors and a backshell kit for making custom 68-pin cables are available from NI.

NI recommends that you use one of the following connectors with the I/O connector on your device.

  • Honda 68-position, solder cup, female connector
  • Honda backshell
  • AMP VHDCI connector

For more information about the connectors used for DAQ devices, refer to the KnowledgeBase document, Specifications and Manufacturers for Board Mating Connectors.
