Signal Insertion Switch Modules: Switches Cable and Accessory Compatibility

Publish Date: Feb 19, 2018 | 0 Ratings | 0.00 out of 5 | Print

Overview

Use this guide to match your NI Signal Insertion Switch models PXI or PXI Express (PXIe) device with a compatible cable and accessory to meet the needs of your application, whether you are creating a new configuration, replacing or expanding your current configuration, or verifying that existing parts can be used in a different configuration.

PXI Signal Insertion Switch Modules, also known as fault insertion units (FIUs), provide a set of feedthrough channels, which make the switch transparent to the system when closed. You can open or short these channels to two fault buses, allowing you to simulate open or interrupted connections as well as shorts between pins, shorts to battery voltages, and shorts to ground on a per-channel basis.

This page is part of the NI Switches Cable and Accessory Compatibility Guide.

4. Known Limitations and Additional Information

This section is important to review because not every cable and accessory combination allows access to the full functionality of your NI Signal Insertion Switches device or module. This list contains notes about known limitations when using certain combinations of Switches cables and accessories. If your device or cable is not listed in this section, there are no known exceptions for it.

Review this table to identify potential limitations and known issues with your device or module.
Model or Accessory Note
2515
  • This model has both a VHDCI and BNC connector. To use this device you will need cabling and/or accessories for both connector types.

5. Glossary of Terms Used

  • Bayonet Neill–Concelman (BNC) - Simply known in industry by its acronym, BNC is a quick connect/disconnect for coaxial cables to assist in noise reduction. In this configuration, a signal is carried down the spline (or pin) of the BNC cable, and the COM(AI-), GND or SENSE is carried down the shielding of the BNC cable. Click here for an example.
  • DIN (Deutsches Institut für Normung) Connector-  Industry standard connector that is used on 100-pin and 160-pin Switches cable and accessory connections.
  • D-Sub (DSUB) - Industry standard D-shaped connector that is used on 8-pin, 37-pin, 62-pin, 78-pin  Switches cable and accessory connections. Click here for an example.
  • Front Mounted Terminal Block- An accessory solution that connects directly to the front of a module. These accessories can be shield or unshielded, they also can allow for the user to directly access the signal on the front of the module or may require additional cabling or accessories to access the device signals. Click here for an example.
  • Remote Terminal Block- An accessory solution that requires a cable to connect to the module. This accessory can be connected, using the cable, directly to the module, or it can be connected, using a cable, to additional accessories. Click here for an example.
  • Very-High-Density Cable Interconnect (VHDCI) - An improvement on the SCSI 68-pin connector featuring .8 mm pin spacing, allowing a smaller footprint and fewer bent pins during connection. Click here for an example.
