I want to know if I can use my cable to transfer the program from a Sharp ER-A550S to a ER-A570? I have the service key. I used this cable to transfer programs before, but it was between two 550s.

The file structure is probably different between the two as the 570 is more powerful. It still might work for PLUs and departments etc so it is probably worth a try if you don't mind wiping the data in the receiving register.

If anyone needs manuals for the Sharp ER-A550 or ER-A570, c-tech has them here:
