ABSTRACT:
A transmitting system including a controller for supervising an address polling system; and a plurality of transmitting modules; connected in cascade to a pair of transmitting paths extending from the controller, for executing polling transmissions from the controller by using a logical address set in each transmitting module; wherein the controller sends a command message for setting the logical address and each transmitting module includes: a switching element circuit for opening and closing between input and output terminals connected to the transmitting paths; and a signal processing circuit for setting the logical address to an address assigned by the command message when a polling address of the command message is identical to the logical address, and for providing a signal to the switching element circuit according to the logical address.
