5 Firmware-Update
To perform a firmware update, the program GBL_Conf.exe and the latest firmware is needed.
•
Enable the bootloader mode (see Chapter Bootloader Mode).
•
Start GBL_Conf.exe.
•
Select the device for which a firmware update is to be performed.
•
Click „Program Device“ and then select there „Firmware Update“.
•
Specify the firmware file that should be uploaded.
Upon completion of the update process, please start the new firmware of the device. You can do this by simply
leaving the bootloader mode.
A firmware update, unlike other functions, is not sent as a network broadcast. Therefore, the device must have a
valid IP address and a valid netmask before the firmware update. If necessary, please correct the entries in GBL_
Conf.exe in bootloader mode and save them with „Save Config“.
If after a firmware update, the web page is not displayed correctly anymore, this may be related to the interaction
of Javascript with an outdated browser cache. Not always helps a Ctrl-F5, it is recommended that you manually
delete the cache in the browser options. Alternatively, you can test start the browser in „private mode“.
