Notes regarding the interface configuration:

Audio + PTT are always available independently from serial CAT and they work for minimum required digital modes configuration with any radio
CAT configuration is done with solder jumpers and can not be changed operationally
Check the transceiver cables listing for your radio. The description will have CAT configuration requirements
