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.
