Updating the Firmware
From time to time there may be new firmware released for the ID-O-Matic III. The processor
has a “bootloader” built in that can accept new firmware from your PC. The process is relatively
quick and painless.
Unplug and remove power from the ID-O-Matic III. Be sure to exit any terminal program you’re
using, such as PuTTY or Minicom. Plug a shorting jumper over the two pins marked “LOAD”
near one corner of the board. If your board doesn’t have pins installed, you can temporarily
short the two solder pads with a short piece of wire or something similar.
With the jumper installed, plug the ID-O-Matic III into your computer’s USB port and start your
terminal program. You should see a message on your screen as shown:
Open the upgrade file (the file with the .HEX extension) with Notepad. Select all text (Control-
A) and copy it (Control-C). Now remove the jumper from the LOAD pins or solder pads. When
you see the message “Send file (plain ASCII)”, simply paste in the text you just copied. If
you’re using PuTTY, it’s easy - just place your mouse in the terminal window and
right-click
once.
You’ll see the LED blink rapidly alternating red and green, and there will be some hash marks
printed as the file is loaded. It’s best not to disconnect the board during this process, but you
