Abstract

A communication system includes a power line, a plurality of PLC networks connected to the power line in common, and an electronic control unit for controlling an electric equipment, connected to the power line between the PLC networks. The electronic control unit includes a bypass capacitor that attenuates a communication signal transmitting over the power line.

Claims

1. A communication system, comprising:

a power line;

a plurality of PLC networks connected to the power line in common; and

an electronic control unit for controlling an electric equipment, the electronic control unit being connected to the power line between the PLC networks,

wherein the electronic control unit includes a bypass capacitor that attenuates a communication signal transmitting over the power line.

2. A communication system, comprising

a power line;

a plurality of PLC networks connected to the power line in common; and

a junction connector provided on the power line between the PLC networks,

wherein the junction connector includes a capacitor that attenuates a communication signal transmitting over the power line.
