OPERATION GUIDE
Note
5.3 Save Setting Command Options
By specifying the option ‘/W’ as continuation of a command, command values can be fixed in the EEPROM within
the MU-4. The next time the power is turned on, the contents of the EEPROM are set to the initial values. The time
required for conversion is 65 ms.
The commands that can specify the option ‘/W’ are as follows.
BR, CH, CT, DI, EC, EI, GI, MD, PB, PW, RI, RM, RR, RT, SB, SI, TC, TB, UI
Example: Fix the User ID as 0000h (UI=0000 is for testing)
Control command:
@UI 0000,0B27 /W C

1. The command parameter is applied immediately after the command to change it is issued. In particular, note
that if the UART related parameters are changed, communication will not be possible unless the UART
parameters on the control side are also changed.
2. The maximum number of EEPROM conversions is 1,000,000. Do not design a program which needs to be
rewritten repeatedly.
3. Do not issue other commands during conversion of the EEPROM.
