Programming of address of peripherals on a control bus used in air conditioning control in motor vehicles, uses bus with breaks in data or supply line which are bridged when peripheral is plugged in to allow address programming

摘要

The address programming operates on a bus with electrical breaks in data or supply line. A peripheral (11) is connected at the break (5') nearest the addressing device (14), and restores continuity at this location. The address of this peripheral can now be programmed. This is repeated with successive peripherals (12, 13) which are plugged into breaks, moving along the bus.
