Case 2: Can-Box Does Not Receive The Reverse Gear Signal - r.LiNK 27-590 Manual

2.5.1.2.

Case 2: CAN-box does not receive the reverse gear signal

If the CAN-bus interface does not deliver +12V on the green wire of the 6pin to 12pin 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 signal contains electronic
interference, a traditional open relay (e.g AC-RW-1230 with wiring AC-RS5) or filter (e.g. AC-
PNF-RVC) is required. Below schema shows the use of a relay (normally open).
Connect the green cable of the 6pin to 12pin cable to the output connector (87) of
the relay.
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 with the green cable before.
Connect permanent power +12V to the relay's input connector (30).
Note: Don't forget to set the Dip 5 to ON.
