After-market rear-view camera
Some vehicles have a different reverse gear code on the CAN-bus which the video-interface
is not compatible with. Therefore, there are two different ways of installation. If the video
interface receives a signal of the reverse gear, the grey coloured wire
“Reverse-OUT”
should
carry +12V while the reverse gear is engaged.
2.5.1.
Case 1: Interface receives the reverse gear signal
If the interface de12V on the grey coloured output wire
“Reverse-OUT”
of the 10pin
PNP Power/CAN cable while reverse gear is engaged, the video interface will automatically
switch to the rear-view camera input
“IN”
while the reverse gear is engaged.
If the video interface does not d12V on the grey coloured wire
“Reverse-OUT”
of the
10pin PNP Power/CAN 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 following diagram
“Case 2: Interface does not receive the reverse gear signal” shows the connection type of
the relay.
