Setting for "Backup setup data"
The "Backup setup data" function should only be used if MD11280 $MN_WPD_INI_MODE is
set to 1 (default setting). Otherwise, when the NC is started for the first time after selecting the
part program, a file with the same name with the ".ini" extension would be automatically
executed.

coded characters to make the number of positions set to "1" an uneven
number (uneven parity) or to an even number (even parity).
● None (default setting)
● Odd
● Even
Number of stop bits for asynchronous data transfer.
● 1 (default setting)

Stop with end of data transfer character
The default setting for the end of data transfer character is (HEX) 1A.
Time monitoring
For data transfer problems or at the end of data transfer (without end of
data transfer character) data transfer is interrupted after the specified
number of seconds.
The time monitoring is controlled by a time generator (clock) that is star‐
ted with the first character and is reset with each transferred character.
The time monitoring can be set (seconds).
