Abstract
An arrangement for providing electrical remote control of several magnetic solenoid valves having a transmitter section and a receiver section. The transmitter includes a fixed frequency signal generator for producing signals having an adjustable duty cycle. The duty cycle of the periodic signals varies in accordance with the position or deflection of an adjustable control lever. The periodic signals are transmitted over a first transmission link to the receiver section for controlling the condition of the magnet valves. A second transmission link is utilized for transmitting digital coded address information concerning which of the magnetic valves is to be selected in the receiver section in accordance with the position of the control lever in the transmitter section.
