225D INDICATOR
FIRMWARE UPDATE
INSTRUCTIONS
Items Required
•PC with Microsoft Windows OS and USB port
•AVR-ISP program (Either AVRISP-U or AVRUSB)
•AVR USB interface cable (Dongle)
•Firmware HEX file downloaded from the dealer-protected software section of
CardinalScale.com. Download the file from CardinalScale.com by navigating to 225
Navigator > Resource Type > Software >.
1. Install the AVR software on your computer if not already installed. Please note that either the
AVRISP-U or AVRUSB software/hardware will work with these instructions. Otherwise,
proceed to step 2.
•Refer to Figure 1 on the next page for the AVRISP-U program.
•Refer to Figure 2 on the next page for the AVRUSB program.
IMPORTANT! When loading the AVR program on your computer, do NOT
connect the USB cable to the computer until the AVR program has been loaded
and is operating.
Failure to do so could allow the computer to assign an incorrect driver to the
AVR dongle.

IMPORTANT! If the message in Figure 3 appears after connecting the AVR dongle interface
cable to the PC, follow the update wizard to update the firmware. Note that this will require an
internet connection.
Warning!Do NOT connect the ribbon cable to the indicator during this process.
Connecting the ribbon cable to the indicator while updating the firmware may cause the indicator
to fail!

2. Save the indicator firmware HEX file to a location on your computer such as My Documents.
IMPORTANT! Confirm that the indicator firmware is in a hex file format where the file name
ends with .hex such as 225D.hex or if custom firmware such as B12345.hex or SO123456.hex.
Should the file be compressed, the file name will end with .zip such as 225D.zip. Zip files must
be decompressed before they can be loaded into the indicator. To decompress the file, save
the .zip file to a location on your computer that will be easy to locate like My Documents, then
open the file. The window will have an option to Extract all files. See Figure 4. Click on this and
use the folder extraction wizard to decompress and save the file(s). Ensure that you select a
location to save the file to such as My Documents so you can locate the file when using the
AVR programmer. See Figure 5.

3. Power the 225D on.
4. When the 225D is in the operation mode, connect the AVR dongle ribbon cable to the port
labeled P8 2560 ISP on the 225D circuit board. See Figure 6.
IMPORTANT! Connecting the dongle to the ISP port before the indictor is fully operating
will cause connection problems.
Figure 6
5. Connect the dongle to a USB port of the computer and open the AVR program.
IMPORTANT! If the message “Your ISP requires a firmware update” is displayed, see
page 3 for instructions.

6. Click on the Reset button in the AVR program. A message will be displayed at the bottom left
of the AVR screen in the Status Box indicating the condition of the connection. See Figure 7.
•RED light indicates a problem with the connection.
•GREEN light indicates a good read along with the processor detected.
NOTE: The correct processor for a 225D will be “Detected device: ATmega2560”.
Figure 7
Device shown must match device
detected in Status Box
IE: ATmega2560

7. The detected device shown in the Status Box must match the Device window at the top of the
screen. See Figure 7. If they do not match use the drop-down list of the Device window to
select the correct device.
NOTE: The correct device for the 225D Main PC Board is ATmega2560.
Note that some revisions of the AVR software will automatically detect that the device is
incorrect and ask to change to the correct device. See Figure 8.

“ATmega2560”. Click on YES
to swap Device selected to
“ATmega2560”

8. Next, read the Fuse settings from the 225D Main PC Board. From the menu list at the top of
the screen select Device, Read,and then Fuses. See Figure 9.

9. The Fuses and Lock Bits screen will open after it reads the fuses of the indicator. The correct
settings are shown in Figure 10.
IMPORTANT! Ensure that the values read, match the values shown in Figure10.
If necessary, change the values that do not match.
Failure to do so will cause the 225D to fail!
