The CX combine is equipped with a minimum of 6 electronic modules, and may be equipped with as many as 10
modules, depending on the configuration and options installed. These modules are:
Main Display Module (MDM) (1) or InfoviewTM monitor; provides the main display of information for the operator.
Shaft Speed Monitor (SSM) (2) provides the display for shaft speed alarms, and for fuel level and coolant temp gauges.
Right Hand Module (RHM) (3) most operator inputs, including from the multi-function handle (MFH), are fed into this
module, which then reports this information to the other modules in the network for action.
Chassis Control Module (1) (CCM1) and (2) (CCM2) (4) these modules drive most of the actuators and solenoids,
and monitor most of the sensors and switches on the combine.
Header Height Control (HHC) (5) module is located on the main stack valve assembly. It receives inputs from the
feeder angle and lift pressure sensors on the combine and height sensors on the header, and controls the accumulator,
header raise/lower and header tilt solenoids.
Chassis Control Module (3) (CCM3) (6) [optional] is installed and used to control certain options on the combine, such
as the precision farming devices.
Data Logger Unit (DLU) (7) [optional] is available with some precision farming systems, and records data provided by
the precision farming sensors.
Differential GPS module (8) [optional] is available with some precision farming systems, and provides location data
to be recorded with the harvest data for mapping purposes.
Engine Control Unit (ECU) (9) [optional] is installed on certain engine models to provide enhanced engine control and
performance.
