COMMUNICATIONS
DGC-2020 communication settings include setup parameters for CANbus, ECU, modem, and RS-485
communication.
CANbus Setup
The DGC-2020 CANbus interface provides high-speed communication between the DGC-2020 and the
engine control unit (ECU) on an electronically controlled engine. When ECU support is enabled
A
, the
DGC-2020 will ignore the analog coolant temperature, oil pressure, and engine speed inputs and rely
upon the ECU for these parameters. The DGC-2020 will also stop calculating engine run time and begin
using the run time recorded by the ECU.
When enabled
B
, the DGC-2020 will receive and retain unsolicited diagnostic trouble codes (DTCs) from
an ECU with DTC capabilities.
A DGC-2020 operating on a CANbus network is identified by a unique address number
C
.
In applications where the ECU is not continuously powered, the DGC-2020 has provisions for applying
power to the ECU and pulsing the ECU to update its engine monitoring data. Either the DGC-2020 Fuel
Solenoid or Pre-Start relay output can be used to apply power to the ECU
D
. If the Pre-Start contact is
