LIGHT CURRENT SWITCHING AND ITS EXTENSION TO SERIAL DATA TRANSMISSION
D M Embrey · 1984
Multiplex signalling systems for use in motor vehicles have always seemed to be seven years away. I would like to describe the approach that my company has adopted in pursuing this path. Firstly from heavy current conventionally switched systems to light current switching using discrete switching lines to a microprocessor and secondly to the assembly of the input and output signals to that processor in a serial data or multiplexed form.
