Claims

[Scope of utility model registration request]

(1) In a transmission device that connects transmission devices such as a master unit and slave unit to one transmission line in a multi-drop manner and randomly transmits data between each transmission device, the above transmission is performed by each transmission device by itself. Providing exclusive state detection means for detecting a proprietary state of the line for a certain period of time or more, and providing a control CPU incorporated in each of the transmission devices in those transmission devices,
The transmission device is configured to be reset by the output of the exclusive state detection means that has been detected.

(2) In a transmission device that connects transmission devices such as a master unit and a slave unit to one transmission line in a multi-drop manner 1, and performs data transmission randomly between each transmission device, the above-mentioned transmission is performed by each transmission device by itself. In addition to providing an occupancy state detection means for detecting an exclusive state of the line for a certain period of time or more, normally closed switch means are connected to the transmission output terminals of each of the above-mentioned transmission devices, and these switch means are provided in each of the above-mentioned transmission devices. A transmission device configured to be opened by the above-mentioned exclusive state detection means or output.
