Transmitting system with address polling for providing a control signal to open/close switch
First Claim
1. 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 said controller may send a command message for setting the logical address and each transmitting module comprises;
a switching element circuit for opening and closing input and output terminals connected to said 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 an opening/closing control signal to said switching element circuit depending upon the logical address.

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.
