Firmware
Overview
Occasionally, it may be necessary to update the firmware in the DG3 for any of the following two reasons:
There is an error in the functionality of the controller that affects its operation.
All software changes are tested thoroughly before release but even in the most rigorous test regime, it is
possible for bugs to remain undetected. Most installations deploying standard, well-proven functions are
very unlikely to be affected by bugs of this type.
An update is needed in connection with a new feature.
DG3’s firmware version
To know which firmware version your DG3 is equipped with, there are two ways of checking it:
1
st
way: Press the F/E key for a few seconds. The firmware version will be displayed as DERIC-G3
V1.XX. In this case, the firmware version will remain on the screen for a few seconds before it
reverts to the last standard driver’s screen as before F/E key was pressed.
2
nd
way: Press the F/E key, the lock code must be entered, 'Show status?' found from within the
list and then selected using the F/E key. The firmware version will be displayed as DERIC-G3
V1.XX. In this case, the firmware version will remain on the screen until you exit the function by
pressing on the F/E key or left arrow key.
For any enquiry about the latest released firmware version, please contact Hanover (please refer to section
4.3 Hanover Technical Support).
Firmware update procedure
Firmware for the DG3 can be loaded via an USB stick as follows:
Obtain a copy of the latest firmware from
Hanover and save the file on a standard
Windows PC. The file will be named:
firmware.han.
Insert the USB stick into the PC and locate
it. It appears as REMOV DISK (E:).
Note: The name and drive letter are
variable and in this case, the drive letter
allocated to the USB stick by the PC is 'E:'.
Be careful as a firmware update will erase the controller’s database which will need to be
uploaded again afterwards.
