Uploading Device Packages (Firmware/Language Module)
A device package contains firmware and a language module. Embedded firmware is the operating
program that controls the actions of the DGC-2020. The DGC-2020 stores firmware in nonvolatile flash
memory that can be reprogrammed through the communication ports. It is not necessary to replace
EPROM chips when updating the firmware with a newer version.
Future enhancements to the DGC-2020 functionality may make a firmware update desirable. Because
default settings are loaded when DGC-2020 firmware is updated, your settings should be saved in a file
prior to upgrading firmware.
The language of the front panel LCD can be changed by uploading a different language module into the
DGC-2020. The DGC-2020 is capable of storing two language modules in nonvolatile flash memory that
can be reprogrammed through the communication ports. The active language module being used for the
front panel LCD is selected on the Front Panel HMI setting screen. To access this screen, use the
Settings Explorer within BESTCOMSPlus to open the General Settings branch and select the Front Panel
HMI screen.
Uploading Firmware/Language Module to Device
If you have obtained an updated device package containing firmware/language module for your device,
you may upload it by performing the following steps:
1. Place the DGC-2020 in Off mode. This can be accomplished by clicking the Off button on the
Control screen inside the Metering Explorer or by pressing the Off button on the DGC-2020 front
panel.
2. Select Upload Device Files from the C
ommunication pull-down menu.
CAUTION
If power is lost or communication is interrupted during file transfer, the DGC-2020
will cease operating and will not recover automatically.
