Case 2: CAN-box does not receive the reverse gear signal
If the video interface does not d12V on the green wire of the 12pin cable when
reverse gear is engaged (not all vehicles are compatible), an external switching signal from
the reverse gear light is required. As the reverse gear light’s power supply isn’t voltage-
stabile all the time, an ordinary open relay (e.g AC-RW-1230 with wiring AC-RS5) or filter
(e.g. AC-PNF-RVC) is required. The diagram below shows the connection type of the relay.
Disconnect the green cable’s preconnected male- and female connectors of the 12pin
interface cable and connect the green input cable
“Reverse-IN”
to the output
connector (87) of the relay.
Note:
Last but not lot least to avoid short circuits, the best solution should be, to
crimp a male 4mm connector to the relay’s output cable and connect it to the green
cable’s female 4mm connector. The output-cable
“Reverse-OUT”
remains
disconnected as it’s out of function.
Connect the Reverse light’s power-cable to coil (85) and the vehicle’s ground to coil
(86) of the relay.
Connect the output connector (87) of the relay to the rear-view camera’s power-
cable, like you did it to the green
“Reverse-IN”
cable before.
Connect stabile and per12V to the relay’s input connector (30).
