GF54.50-P-4101-01GH
Electronic compass, purpose
n
The electronic compass (B26) determines the current route
of the
vehicle using the
earth's magnetic field
and passes the appropriate
data to the trip computer control module (N41) via a two-wire
interface (RS485).
The compass has a calibration mode to allow the route to be
determined as accurately as possible. In this mode the compass can
be adapted to the magnetic conditions around the vehicle.
