Abstract
A remote control system and method therefor is disclosed that includes a control station coupled by a two-wire line to a base station having a transmitter for providing simplex radio communications to mobile radios. The control station utilizes digital pulsed DC signalling to select a radio channel of the base-station transmitter for transmission of each message. In response to activation of a transmission switch, the control station applies a DC voltage to the two-wire line and thereafter applies a command pulse train having a predetermined number of pulses corresponding to the selected radio channel. The base station is responsive to the DC voltage on the two-wire line for receiving the command pulse train. The pulses in the received command pulse train are totalized, and the base station transmits the message on the radio channel corresponding to the totalized number of pulses.
