3 System Description
3.1 System configuration
As standard, the SmartBoard is operated in combination with Trailer EBS and dis-
plays the data transmitted by Trailer EBS.
The SmartBoard is connected to Trailer EBS. The tyre pressure monitoring system
IVTM and the BVA (brake lining wear indicator) are connected to Trailer EBS and
so transmit their data to the SmartBoard via the Trailer EBS.
The odometer obtains information from the Trailer EBS. In order to operate the
SmartBoard's internal odometer independently of the Trailer EBS D function (and
also without an ABS plug connection to the towing vehicle), the SmartBoard must
be connected directly to the wheel sensor via the Y-cable. This is not required if
there is a connection to Trailer EBS E: the wheel sensor signal is transmitted to the
SmartBoard even when not supplied with power from the towing vehicle.
Control of the air suspension functions (e. g. lifting and lowering the lifting axle or
the chassis/vehicle body) requires the Trailer EBS E to be configured accordingly.
