2.5.3. 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 green wire
“Reverse-OUT”
of the 20pin
cable should carry +12V while the reverse gear is engaged.
Note:
Do not forget to set dip5 of the video-interface to ON before testing.
2.5.3.1.
Case 1: Video interface receives the reverse gear signal
If the CAN-bus interface de12V on the green wire of the 20pin cable when reverse
gear is engaged, it will automatically be switched to the rear-view camera input CAM while
reverse gear is engaged.
The 12 V power supply for the rear-view camera (max 3A) has to be taken from the
green wire
“Reverse-OUT”
of the 20pin cable to avoid an unnecessary permanent
power supply to the camera electronic.
For the operation, both green cables
”Reverse-IN“
and
“Reverse-OUT“
have to stay
connected.
