Abstract
A primary transceiver having a driver/receiver initially drives a bus while a secondary transceiver having a driver/receiver receives the signals present on the bus. The system compares the signals received by the secondary driver/receiver and the inputs to the primary driver/receiver. If a difference is detected, the system controller disables the primary driver/receiver and enables the secondary driver/receiver which drives the bus.
