USB Interface
A mini-B USB socket enables local communication with a PC running BESTCOMSPlus software. The
DGC-2020 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-2020 termination).
RS-485 Communication Port
DGC-2020 controllers with the optional RS-485 communication port (style number xxxRxxxxx) are
equipped for polled communication over a Modbus™ network. Twisted-pair, shielded cable is
recommended for RS-485 port connections. RS-485 communication port terminals are listed in Table
6-10.
Table 6-10. RS-485 Communication Port Terminals
Terminal Description
12 (485 SHIELD) Shield connection for RS-485 cable
13 (485B) RS-485 send/receive B connection
14 (485A) RS-485 send/receive A connection
CANbus Interface
These terminals provide communication using the SAE J1939 protocol or the MTU protocol and provide
high-speed communication between the DGC-2020 and an MTU engine ECU on an electronically
controlled engine. Connections between the MTU engine ECU and DGC-2020 should be made with
twisted-pair, shielded cable. CANbus interface terminals are listed in Table 6-11. Refer to Figure 6-4 and
Figure 6-5.
