How to Connect Signals to an NI Switch


This guide explains how to connect signals to your NI Switch. When connecting signals to your Switch you will need to identify what front-mounted terminal block, or cable and remote terminal block that you would like to use for your application. Some switches also have the option for users to create a custom connector or cable solution to connect signals. This article will walk through the necessary steps to connect signal to your switch and provide additional resources for your specific switch model, cable and accessories.
