RKE Module

The Remote Function Actuator (RFA) module performs the functions of interpreting the signals from the transmitters and relaying the information to other modules via class 2 serial data. The RFA module does not directly control any functions. The RFA module is able to differentiate between the various transmitters and must be programmed in order to accept signals from all transmitters if one or both transmitters are to be replaced or if spares are added.
