Thanks. I am running my old Corona V1 module in PPM mode and comparing it to the output from the Multi module. Pascal is assisting me in defining the Corona V1 protocol. The Multiprotocol module has so many protocols and on my Taranis I see where I can enter values on many protocols. I am not sure what some of these values are used for, most have a name. I know about the V1 V2 Coronas. I wanted to verify what the second value was used for.
