Receiver board has a microprocessor control unit with LEDs and buttons; executive elements realized on two relays; and screw
connectors for connecting the power supply, antenna and controlled devices.
The controlled device must be connected to the receiver output. If the device requires normally open (NO) control, connect the
device to the terminals NO andC. If device requires normally closed (NC) control, connect the device to the terminals NC andC.
The receiver is equipped with a rod antenna. In order to increase the radio coverage use an external antenna using coaxial cable
with an impedance of 50Ω. Connect antenna's coaxial cable to the terminal marked
markedGND
.
12-24V AC/DC connection is indicated by PWR LED. During receiver operation, each switching of C1/C2 output channel is
