After-Market Rear-View Camera; Case 1: Can-Box Receives The Reverse Gear Signal - r.LiNK 27-590 Manual

2.5.1. After-market rear-view camera

Some vehicles have a different reverse gear code on the CAN-bus which the included CAN-
box is not compatible with. In this case there are two different ways of installation. If the
CAN-box is able to detect an enabled vehicle's reverse gear, the green wire of the 6pin to
12pin cable should carry +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of video-interface to ON before testing.
2.5.1.1.

Case 1: CAN-box receives the reverse gear signal

If the CAN-bus box delivers +12V on the green wire of the 6pin to 12pin cable while reverse
gear is engaged, the video interface will automatically switch to the rear-view camera input
"CAMERA-IN" while the reverse gear is engaged.
Additionally, the +12V (max. 500mA) power supply for the rear-view camera can be
taken from the green wire of the 6pin to 12pin cable.
