RELAY SYSTEM, RELAY DEVICE AND SYNCHRONIZATION METHOD

摘要

When no synchronization signal is transmitted over a system bus (115), a master repeater is arbitrarily selected from a plurality of repeaters (111 2 to 111 n ), starts transmitting a synchronization signal over the system bus (115), and transmits information to the system bus (115) in synchronization with the synchronization signal. Other slave repeaters transmit information to the system bus (115) in synchronization with the synchronization signal transmitted by the master repeater.
