2.6.2.2. Case 1: CAN-Box supports Reverse Gear
In case the Can-Bus-Box delivers +12V to the green wire 6Pin to 8pin cable while reverse
gear is engaged, the Interface switches automatically to CAM input.
In addition power supply of +12V (500mA max.) of the After-Market Rear View
Camera can be realised by the green wire of of 6Pin to 8pin cable
2.6.2.3. Case 2: Can Box does not support reverse gear
In case the Can-Bus-Box does not deliver +12V to the green wire 6Pin to 8pin cable while
reverse gear is engaged (not all of the vehicles are compatible) an external switch-over signal
of the reverse light will be required. Because of the fact that the reverse light signal is not
free from electronic interferences, a relay (eg. AC-RW-1230 with AC RS5 wiring) or an
interference filter (e.g. AC-PNF-RVC) will be required. The diagram below shows the use of
the relay.
Disconnect green cable of 6pin to 8pin cable near the black 8pin connector .
Isolate short end of the green cable (CAN-Box side).
Connect Reverselight/Power with Coil (85) and Ground (86) to relay.
Connect power of rear-view camera and the green cable (Video Interface side) of
6pin to 8pin cable with relay output (87)
Connect continuous battery current to relay input (87)
