VER: Displays versions of the main microprocessor and
sub microprocessor, communication compatibility
between the main microprocessor and sub-
microprocessor and the communication version of
RS-232C.
As for communication compatibility between
microprocessors, if alphabets are the same, their
communication formats match but if they are not the
same, proper operation is not available.

Please note that no program is written into the
microprocessor supplied for servicing. Therefore, it is
necessary to write the program when the microprocessor
is replaced. (For the details, refer to "UPDATING
FIRMWARE".)
When replacing the microprocessor, be sure to check
the microprocessor compatibility before replacement.
The microprocessor may not be suitable for
replacement depending on its communication format.
Use of a microprocessor whose communication
format is not compatible with the existing one will
