Updating your tuner
The firmware in your tuner can be updated by running an update utility provided by LDG. This
will give you access to the latest features and performance enhancements. You will download two
files from the LDG web site: the updater program, and the update hex file.
1. Download the updater program from the LDG web site. Unzip the file to your desktop (or
any other convenient folder), and run the setup program. Follow the installation
instructions. The default install file is:
c:\ldgelectronics,Inc\AT200OPCFirmwareDownloader
2. Download the update file; these have a .hex file type.
3. Run the updater program.
4. Click the "COM?" button to select the COM port. Select the appropriate port and click
Apply.
5. Click the "Load File" button, then navigate to the .hex file you downloaded, and select it.
6. Click "Send To Tuner" to load the file into the tuner.
7. As the file loads, each line of hex code is displayed in the loader window. Present
releases contain upwards of 1,000 lines of code.
