Example: Writing Data – General Procedure
1
Writing is done as following proceedure.
1. Read out setting
Execute Command "R" (Reading out setting) on the target parameter. Set "Address" at "DATA1" and "DATA2".
2. Write setting
Execute Command "W" (Writing the setting) on the target parameter. Writing data is done to the address set at "1. Read setting".
3. Write to EEPROM (see J
