Terminals and Connectors DGC-2020HD
An Ethernet connection to a PC running BESTCOMSPlus provides remote metering, setting,
annunciation, and control of the DGC-2020HD. Ethernet communication between DGC-2020HDs allows
for generator sequencing on an islanded system.
RS-232 Interface
A male DB-9 connector allows the DGC-2020HD controller to connect to an external, user-supplied dial-
out modem via the RS-232 interface. The modem enables the DGC-2020HD to dial up to four pager
telephone numbers and annunciate conditions selected by the user. These conditions include any
DGC-2020HD alarm or pre-alarm, closure of any programmable contact input, and an active cool down
timer.
