2.5.4.
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.
2.5.4.1.
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 of the 20pin cable to avoid an unnecessary permanent power supply to
the camera electronic.
