Transmission of the signals between the ECU's of the preceding and succeeding vehicles within the road train is implemented by the router. It is done on a:
- Towed trailer with two EBS units installed (must be the last trailer in the train), or
- Where communication between ECU's installed on each of the vehicles needs to be provided
Wiring diagram example can be found in installation guide.
Both EBS units are connected to the same EB+ CAN Hub and both have the same trailer VIN number. This can be implemented only on the last trailer on the road train.
