(
) Numeric key number 227 is the system menu display key.
When the touch switches allocated as numeric keys and system keys on a numer-
al setting screen are pressed, no notification is made to the PC. This means that
when using the NT20S-ST128 (RS-232C), the touch switches numbered 227 to
255 cannot be used as normal touch switches on a numeral setting screen.
