V2 Firmware Revisions
The firmware on displays is able to be updated by the user to add more features or fix bugs. Note: Upgrading
the firmware unfortunately means you will lose settings in the EEPROM - options/injector setup, and time trial records.
Download the UpdateCommander application below and then download the firmware version you wish to update to from below:
UpdateCommander application - extract to a directory (no installation needed)
v2.00 - Aug08 Initial release - extract the .enc from zip
Firmware Upgrade Pre-requisities:
- Your Car - for power to the LCD display
- Your V2 Display - duh! You'll need the USB cable plugged in, with drivers installed on your laptop. See the
userguide for USB driver installation.
- Your Laptop - to run the UpdateCommander program that updates the firmware
- UpdateCommander.exe - the program that
updates the firmware
- The .enc firmware file (extracted from the zip) - whichever version you want to update to - see list above
Firmware Upgrade Steps:
- Turn on the car (not running, just so LCD is turned on)
- Turn on your laptop
- Connect USB cable from LCD to Laptop
- Open UpdateCommander.exe on your Laptop, leave it on the COM port tab
- Choose the COM port for your USB cable (most likely the only port displayed in drop down).
- Leave Baud Rate at default 115200, leave device type as is (will probably say unknown).
- Browse to the firmware .enc file you wish to update to
- Click Program - now the program will wait for the LCD to be reset
- Reset the LCD - go to the main menu, then Options, then Reset, then Reset Now.
If you botch up an update and the LCD doesnt work as per normal, there's 3 ways to get it to update properly:
- Just try again - most likely the display will be kept in a constant 'reset' state, and therefore as soon as you hit
Program, it will start programming it
- The display can be removed from its enclosure, and at the last step as above (to 'reset' it to start upgrade), you
would just short two pins together - I can provide details on this
- If all else fails, the display can be sent back to me for manual program at no cost.
