4.2.8. Upgrading Firmware 3.0
This feature is only available from firmware version 3.0 onwards.
Upgrade DFU (Device Firmware Upgrade) is an option to be taken seriously as it has the potential to leave your product in an unusable state.
The upgrade is a 2 stage process, the menu option must be used in conjunction with the upgrade software supplied on the accompanying CD ROM which requires a Microsoft Windows 95 or later operating system
Selecting option 5 from the main menu displays the following Firmware Upgrade menu.
To activate this feature, you must type the word “PROCEED” exactly. This command is case sensitive.
Typing “PROCEED” correctly will cause the product to enter its firmware upgrade mode with immediate affect.
Failure to enter “PROCEED” correctly will cause the menu option to abort and you will be able to continue navigating the menu in the normal fashion.
In some (but not all) instances you will see some “odd” characters displayed as shown above. This is normal behaviour and indicates the product is ready to receive its firmware upgrade commands from the supporting software.
At this point, you will no longer be able to interact with the menu, nor will you be able to use the product as advertised. ONLY the supporting software can restore this setting. Neither a power reset nor any combination of presses of the reset button will restore normal operation to the product. It is now permanently in a state to upgrade the firmware.
IMPORTANT, in order for the upgrade application to connect to your product and perform the upgrade, you must ensure you disconnect your terminal application from the COM port. In Hyperterminal, this is done either by closing the application down, or Clicking the “disconnect” toolbar Icon
Now run the “upgrade” application documented in the section below for upgrading.
