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. 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.

 

Device List

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.

Glossary of Terms Used

  • 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.
  • Micro Coaxial (MCX)- Industry standard cable characterized by an inner conductor and an outer shielding. Click here for an example.
  • SubMiniature Version A (SMA) - A quick connect/disconnect for coaxial cables to assist in noise reduction, this connector features a threaded barrel and hex nut for mating. Click here for an example.
  • SubMiniature Version B (SMB) - A quick connect/disconnect for coaxial cables to assist in noise reduction, this connector is a smaller size and features a latching mechanism. Click here for an example.
