Matrix Switch Modules: Switches Cable and Accessory Compatibility

Updated Nov 9, 2022

概览

Use this guide to match your NI Matrix 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 Matrix Switch Modules are organized into rows and columns and provide maximum flexibility for switching systems by allowing you to connect any channel to any other channel.

Note: This page does not include RF Matrix Switches. To find compatibility information for NI RF Matrix Switches see the RF Switch Module Compatibility Guide.

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

How to Use this Guide

It is important to work through this guide sequentially to identify and then pair up your device with compatible cables and accessories. To do this, complete the following steps:

  1. Find your module or device in the Device List.
  2. Use the Cable and Accessory Compatibility Tables to identify your device.
  3. Check the Known Limitations and Additional Information List for any known limitations you may encounter.
  4. Note: Using the page search functionality in your browser to locate your model may speed up this process, typically CTRL+F on Windows or ⌘+F on MacOS.

Cable and Accessory Compatibility Tables

Find the compatibility table that matches the pin count and connector type of your device. If you have questions on terminology, refer to the Glossary below. After you have identified the cable and accessory options for your device from this section, move to the Known Limitations and Additional Information List.

Note: Most devices either require a Front Mounted Terminal Block or a Cable and Remote Terminal Block combination. Some select devices can require all three accessories, devices that require all three accessories can be found in the Known Limitations and Additional Information List.

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 Matrix 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
2532B
  • To connect to this module multiple accessories are needed. The 2532B requires that a Front Mounted Terminal Block is connected directly to the module, and then one of the recommended cable kits is used to connect from the Front Mounted Terminal Block, to another module or a remote terminal block. For more information on how to connect accessories to the 2532B please see the Installation Instructions for your Front Mounted Terminal Block.
TB-2634
  • Use of the TB-2634 with the PXI/PXIe-2529 requires a 3rd party ribbon cable that cannot be purchased through NI. More information and manufacturer part numbers for a compatible 3rd party cable can be found in the TB-2534 Installation Instructions.
TB-2645B
2501, 2503. 2530B
  • While the PXI-2501, PXI-2503 and PXI-2530B modules are commonly categorized as multiplexers, they can be configured as both multiplexers and matrices. The Matrix compatibility can be found above and the Multiplexer compatibility can be found on the Multiplexer Compatibility Guide.

Glossary of Terms Used

  • 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.
  • LFH- Industry standard Low-Force Helix connector that is used on 160-pin and 200-pin Switches cable and accessory connections. 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.
  • Ribbon Cable - A low-cost unshielded cable solution. Click here for an example.
  • SCSI 0.050 D-Type -  Industry standard SCSI connector standard featuring 0.050 pin spacing that is used in 68-pin Switches cable and accessory connections. 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.
