EMBEDDED FIRMWARE
Embedded firmware is the operating program that controls the actions of the DGC-500. The DGC-500
stores firmware in nonvolatile flash memory that can be reprogrammed through the RS-232
communication port. It is not necessary to replace EPROM chips when updating the firmware with a
newer version.
Updating the Firmware
Future enhancements to DGC-500 functionality may make a firmware update desirable. Because default
settings are loaded when DGC-500 firmware is updated, your settings should be saved in a file prior to
upgrading firmware. DGC-500 embedded firmware can be updated by performing the following steps.
1. Connect a communication cable between the rear RS-232 connector of the DGC-500 and the
appropriate communication port of your PC. Start BESTCOMS-DGC500-32, open communication,
and gain password access with the OEM-access password.
2. Click Configure on the menu bar and click Upgrade Embedded Firmware. When Upgrade Embedded
Firmware is clicked, the Embedded Firmware Upgrade dialog box (Figure 4-29) appears.

3. Click the Select New Application Code button and then navigate to and select the file (S19 file
extension) to be used for updating the DGC-500 firmware. The file details are displayed in the File
Information section of the Embedded Firmware Upgrade dialog box (Figure 4-30).
CAUTION
If power is lost or communication is interrupted during file transfer, the DGC-500
will not recover and will cease operating.
