A system for a network of one or more off-board subsystems is provided for controlling automobile subsystems such as vehicle lighting. Such a system may be compatible with a universal asynchronous receiver transmitter (UART) interface and it may address timing issues by using a protocol having a synchronization frame (sync frame) such that a clock signal may be recovered from the sync frame sent by an off-board master device, such as a microcontroller unit, to a satellite/slavedevice. Such a protocol permits elimination of a crystal clock oscillator and phase-locked loop located at satellite, thereby dispensing with an otherwise significant cost.
