ACase 2: Video interface does not receive the reverse gear signal
If the video interface does not r12V on the green wire of the 20pin 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-
stable 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 pre-connected male- and female connectors of the
20pin cable and connect the green input cable
“Reverse-IN”
to the output connector
(87) of the relay.
Note:
Not 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 permanent power / 12V to the relay’s input connector (30).
