Matrix Switch Modules: Switches Cable and Accessory Compatibility
Updated Sep 29, 2021
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.
Begin by using the following tables to locate your device or module. Once found, note your connector type, pin count, and any other notes for reference, and then move to the Cable and Accessory Compatibility Tables.
Important Note: "Group" used in this context is solely to categorize devices together that use the same cables and accessories. It does not necessarily indicate similar functionality, specifications, or other commonalities between the devices.
Group 1: 250x,252x and 253x Matrix Device And Modules
Identify your Matrix device or module, then click to jump to the compatibility table.
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.
Group 1: 250x, 252x and 253x Matrix Devices And Modules
Use this table to identify compatible 252x and 253x Matrix cables and accessories.
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
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.
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.
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.
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.
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.
