| Abstract |
This paper handles, implementation of multiple access bidirectional serial communications protocol using DC power lines. The normal voltage of the power communication line maintains 24[V] corresponding to level 1 and the host drops the voltage to 12[V] on sending level 0 signal, also the clients normally keeps the line voltage to 24[V] use pull-down circuit to drop the voltage to 12[V] on sending level 1 signal. Host senses the voltage level of the power communication lines and the hosts switches power source from 24[V] to 12[V]. Experimental circuit is designed with one hosts and four clients and verified the power line voltage switching operation depending on the data signal levels on the power line. |
