hi first floor!

may be fanuc 0mb 0mc has two eprom chips. so it's used fapt ladder soware.
ladder ii is used for fanuc power mate d/h,and fanuc 15,16,18.

In my mind 552 and 553=10 means 4800 baudrate. fanuc 0 has two rs232 ports. they vertical arranged on the board. you can exchange another. normally fanuc only display LSK no input flash. LSK at here means waiting input or now is outputing. because punch and read are two channel in the ic chips, anot...

Desktop computers use +-12V voltage for rs232 ic chips. A Laptop uses single +5v for rs232 ic chips. Inside the ic chips ( for example:max232) it has a dc-dc converter. through +5v to convert into about +- 8V for rs232 voltage demanding. So normally single 5V ic chips overload capability is lower. T...

if using my converter software you can use general eprom w/r
to process fanuc pmc. ANd need not to use fanuc eprom w/r its too expensive and has to use a transformer from 220v to 100v.
