** The baud rate can be changed with the setting values for the communication conditions of the
serial interface. The serial interface communication conditions can be changed using
command and Memory switch setting utility. The setting values are 2400, 4800, 9600, 19200,
38400, 57600, and 115200.
For the memory switch setup utility, see "Memory Switch Setting Utility" (page 3-6).
Note:
The values of the communication conditions of the serial interface set with commands are enabled only
when DIP switches 1-7 and 1-8 are On. Otherwise, the value selected with DIP switch 1 has priority.
