To provide a multiplex transmitter for a vehicle in which communication can be ensured even if a network fault such as disconnection occurs in a plurality of dizzy chained network systems with different protocols.
A plurality of dizzy chained networks 41a, 41b, 41c are connected via a gateway 40 including a protocol converting means 44 for converting protocols among the networks, each of the networks 41a, 41b, 41c comprises nodes 42a, 42d, 42i disposed in one end of the network and nodes 42a, 42f, 42g disposed in the other end of the network and including a fault protocol converting means 45, and the nodes 42a, 42g are connected to the nodes 42g, 42f of the neighboring network. When any fault occurs, the communication within the network where the fault occurs, is performed via the neighboring network connected by the nodes 42a, 42f, 42g.
