The engine PCB (EPCB) transmits the status of each switch to the main PCB (MPCB)
and transmits the control signals output from the main PCB (MPCB) through driver ICs
to motors, clutches and solenoids. It also receives and transmits input and output
signals to and from optional devices via a communication interface.
