Abstract
In a communication device, when an enabling signal is at a high level and a transmit data is at a high level, that is, in a recessive period, both transistors turn off. Thus, potentials of signal lines are determined by power supply from a second transmitting part to a communications network. When an error frame arises in this state, that is, transistors in the other ECU turn on, excessive currents flow the signal lines. When current monitoring circuits detect error currents, an error signal is changed to a high level.
