<p>PURPOSE:To design simplification of transmission lines by connecting two multiplex devices located in front and rear of a door to each other with two transmission lines constituting a closed loop and by connecting a 3rd multiplex device arranged in the door to one of the two multiplex devices above. CONSTITUTION:A 1st multiplex device 11 and a 2nd multiplex device 12 are arranged respectively in front of and backward of a door 6 of a vehicle A while a 3rd multiplex device 13 is arranged in the door 6. The 1st multiplex device is arranged, for example, with respect to switches and devices provided around a driver's seat, the 2nd multiplex device 12 is arranged, for example, with a respect to lamps, a rear wiper and others, and the 3rd multiplex device is arranged with respect to a power window, automatic door lock and others. While the 1st and 2nd multiplex devices 11, 12 are connected to each other via a 1st transmission line 14, they are connected to a 2nd transmission line 15 to which the 3rd multiplex device 13 is connected to constitute a closed loop with both transmission lines 14, 15.</p> |
