Locator Description
A, D The majority of external, DGC-2020 wiring is terminated at 15-position connectors with
compression terminals. These connectors plug into headers on the DGC-2020. The
connectors and headers have a dovetailed edge that ensures proper connector
orientation. Each connector and header is uniquely keyed to ensure that a connector
mates only with the correct header. Connector screw terminals accept a maximum wire
size of 12 AWG.
B The mini-B USB socket mates with a standard USB cable and is used with a PC running
BESTCOMSPlus software for local communication with the DGC-2020.
C DGC-2020 controllers with an optional, internal, dial-out modem connect to a telephone
line through a USOC RJ-11 jack.
E Connections to the DGC-2020 Start (starter), Run (fuel solenoid), and Pre (glow plug)
output contacts are made directly to each relay through quarter-inch, male, quick-connect
terminals.
F An optional battery backup for the real-time clock is available when ordering.
