Installation process state surveillance binary information transmission mechanism having input signals cable passed with first/second over voltage values representing coded state/inactive state and information several receivers passed.

摘要

The binary information transmission mechanism has interface apparatus (20) receiving signals and transmitting them on a cable (21) towards drivers (11). Each set of driver information is coded using a first over voltage value. A second over voltage value signifies an inactive state. The information is passed to several receivers (13) restoring information logic compatible information.
