Throttle lever control system

Terminating resistor at throttle lever control
The Bosch Rexroth throttle lever for the Marex OSII (MPC) controller communicates with the controller in
the engine room through the CAN bus. This CAN bus must always be fitted with terminating resistors at
both ends (start and finish ends).
Caution:
If the CAN bus is not terminated, or if it is incorrectly terminated, then this may result in
disturbances in data communication.
Terminator at start of bus in engine terminal box
The controller in the engine room has an internal terminating resistor (dip switch S1) on the mother board
which does not have to be set. Default setting: S1 set to the right.
Note:
S1: Throttle lever terminating resistor switch
S2: Cross communication terminating resistor switch
Terminator at finish end of bus at throttle lever
The lengths of the CAN busses vary depending on
the number of throttle levers. In any case the CAN
bus must always be terminated at the last throttle
lever with a terminating resistor À
part no. 51.25435−0174.
