Operation Overview
The DECU 3 controls the information shown on the LCD
monitor 4. The controls 6 and LCD monitor are part of the
ECU.
The DECU is connected to the CANbus and is capable of
sending and receiving CAN messages to and from other
CAN enabled ECUs on the machine.
Internal software data enables the DECU to process inputs
and respond by configuring the LCD to show the
applicable graphics and data.
Note: Two LCD variants are available. The 5 in variant
(shown) has two mechanical gauges 5. The 7 in variant
replaces the mechanical gauges with digital gauges shown
by the LCD. This variant also uses the LCD to display the
input from the camera visibility system.
To get access to the electrical connectors on the DECU
remove three screws 1 and cover 2.
