Before you can load firmware through the serial port you need to convert the ROM code to HEX

Put R2H.EXE and the *.ROM file into the same directory on a PC then open a DOS Window to
that directory and type: C:\ R2H
filename

reprogramming will result in a corrupt program image and a nonfunctional unit.
