What's the best way to implement an RF kill for XBP9XT?

I want to implement a hardware RF kill so that the XBP9XT will instantly turn off its RF block. My first though is to pull RESET low. Questions:

  1. Will that stop the RF immediately?
  2. Is that the best way to do it?



No, try using the Shutdown pin. That puts the module to a sleeping state.

Looking at the documentation for the XBP9XT I don’t see a shutdown pin. I have seen them on other Digi radios, but the word shutdown doesn’t occur in the documentation I have.

Sorry that was on the older hardware type B. For the SMT version you would use the sleep pin (Pin 10) and use sleep mode.
