12.2 Receiver
The most important components of the receiver are the Receiver/Decoder Module, the Relay printed
circuit board, the LED printed circuit board, the EEPROM, the Mainline Indicator printed circuit
board, and the Run/Test Switch.
12.2.1 Receiver/Decoder Module
This module combines a narrowband FM receiver, the frequency of which is digitally synthesized,
with a decoder circuit, which converts the audio signal from the receiver to a serial data stream of
relay commands. It contains a micro-controller, which examines the incoming signal and
determines, by means of
the security code and
other information,
whether it contains valid
commands to change the
state of the relays. It then
issues these commands to
the Relay PCB.
12.2.2 Relay PCB
This module latches the
serial relay command
data and drives the output
relays. It also contains
the power supply for the
rest of the receiver.
12.2.3 LED PCB
This module displays the
state of all of the
receiver’s relays by
means of green LEDs
(see Figure 10).
