IPL FUNCTION via RS232 Interface (Later Models)
This function is used to rewrite the Flash ROM program of the main PWB unit for the ER-A520/A530, where
an existing program is written in the Flash ROM and is operating normally. That is, the product must be
operating normally in order to use this function. If the product is not operating normally for some reason,
this function cannot be used. If the Flash ROM itself is defective, replace it with one where the program has
already been written. In this case, there is no need to use this function.

POSTool3.exe (PC software for writing the ROM data).
ROM data file (Example: A520U_1C.ROM).
RS232 crossover cable.
PC (OS: Windows 98SE, ME, 2000, XP).
ER-A520/A530 (where an existing program is already written and is operating normally).
