Load Share Line
Load share line outputs are measured and used to calculate the per-unitized average load level. This
average is used as the setpoint for the genset’s kW controller. Load share line output terminals are listed
in Table 2-16.

IRIG-B Connections
The IRIG-B terminals connect to an IRIG-B source for synchronization of DGC-2020HD timekeeping with
the IRIG-B source. Table 2-17 lists the IRIG-B source input terminals.

Optional Remote Display Panel Connections
Terminals are provided for connection with the optional remote display panel (Basler P/N 9318100114
projection mount or 9318100115 flush mount). These terminals provide dc control power to the remote
display panel and enable communication between the DGC-2020HD and the remote display panel.
Twisted-pair conductors are recommended for making the connections between the DGC-2020HD and
remote display panel. Communication may become unreliable if the connection wires exceed 1,219 m
(4,000 ft). Table 2-18 lists the DGC-2020HD terminals that connect to the remote display panel.

Connectors
USB Interface
A mini-B USB jack enables local communication with a PC running BESTCOMSPlus
®
software. The
DGC-2020HD 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-2020HD termination).
Ethernet Communications
Dual copper RJ-45 jacks or an ST fiber optic port provide Ethernet communications between the DGC-
2020HD and a PC via BESTCOMSPlus or other DGC-2020HDs in a network. The ST type fiber optic port
uses a 1,300 nanometer, near-infrared (NIR) light wavelength transmitted via two strands of multimode
optical fiber, one for receive (RX) and the other for transmit (TX).
