The Autowatch AW3000 Power Comms system comprises of two units. The Transmitter (TX) and Receiver (RX) units.
The Transmitter (TX) is connected to a reversing camera at the back of the caravan and the RX is connected to the reverse wire in the back of the towing vehicle. When the towing vehicle is put into, it powers up both the TX and RX units. The TX converts the reversing camera video signal and sends the data down the existing reverse wire through the 7 or 13 pin plug and into the back of the towing vehicle.
The Receiver (RX) then de-codes the data and sends it to the monitor. There are no additional cables and connectors required to send the data from the caravan/trailer into the towing vehicle.
If using a two camera reversing system, one on the towing vehicle and the other on the towed vehicle, then the monitor software automatically knows to show AV2 when the caravan is connected and AV1 when the caravan is disconnected.
Power line communication (PLC) carries data on a conductor that is also used simultaneously for electric power transmission. On vehicles, Power line technology enables in-vehicle network communication of data, voice, music and video signals by digital means over direct current (DC) battery power-line.
PLC technologies limit them selves to one type of wire. Advanced digital communication techniques have been tailored to overcome hostile and noisy environment and are implemented in a small size silicon device.
