Connections for Volvo Penta EDC III Applications
Engines equipped with Volvo Penta EDC III controllers can receive engine control commands (such as
start and stop) from the DGC-2020 through the SAE J1939 communication interface. To invoke this
feature, the EDC III must receive a J1939 message containing engine control information within one
second of waking (exiting sleep mode). If the EDC III does not receive an engine control message within
the prescribed time, it will enter the stand-alone mode and ignore any J1939 control messages. If this
occurs, the EDC III must be forced back into sleep mode by pressing the auxiliary stop pushbutton on the
engine or by momentarily disconnecting EDC power.
The interconnection diagrams of Figures 6-7 through 6-10 illustrate the DGC-2020 and EDC III
connections that allow the DGC-2020 to awaken the EDC III and start the engine, or simply acquire
engine status information. Wake-up of the EDC III is initiated by using the DGC-2020 RUN output
contacts to apply battery power to the EDC. To stop the engine, the DGC-2020 sends a sleep command
through the J1939 interface to the EDC III and opens the RUN output contacts. This causes the EDC to
stop the engine and enter the sleep mode.
In order for the DGC-2020 to communicate with the EDC III, two DGC-2020 settings must be changed
from their default values.
• The J1939 address of the DGC-2020 must be set at 17.
• The engine start/stop configuration setting must be set for Volvo Penta.
Both settings are configured on the CANBus Setup screen of BESTCOMSPlus. Section 4,
BESTCOMSPlus Software has information about adjusting DGC-2020 settings through BESTCOMSPlus.
