Output Contacts
The DGC-2020ES has three sets of fixed-function output contacts: Pre, Start, and Run. The Pre contacts
supply battery power to the engine glow plugs, the Start contacts supply power to the starter solenoid,
and the Run contacts supply power to the fuel solenoid. Connections to the three sets of contacts are
made at terminals 19 through 24. The Pre, Start, and Run relay terminals are listed in Table 16.

24 (PRE)
Four programmable output contacts are provided in two sets. Each set of two output contacts share a
common terminal. Programmable output contact terminals are listed in Table 17.

USB Interface
A mini-B USB socket enables local communication with a PC running BESTCOMSPlus software. The
DGC-2020ES is connected to a PC using a standard USB cable equipped with a type A plug on one end
(PC termination) and a mini-B plug on the other end (DGC-2020ES termination).
CAN Interface
These terminals provide communication using the SAE J1939 protocol or the MTU protocol and provide
high-speed communication between the DGC-2020ES and an ECU on an electronically controlled engine.
Connections between the ECU and DGC-2020ES should be made with twisted-pair, shielded cable. CAN
interface terminals are listed in Table 18. For typical CAN connections, refer to the Typical Connections
chapter.
