Having some issues with a few DZ-2500Cs. Brought them over to DZ, he lives nearby. He reprogramed them.
I thought at the time that it would be nice if I could reprogram them.
I have the tool to reprogram them, but I don't have the binary file to use. The DZ-2500 uses the Microchip PIC processor, same family as I use in some of my boards.
