Writing to the EEPROM of the JW-21MN, start operation [HEX (hexadecimal), byte]

Write "81(H)" into parameter address 007777(8) and write the set parameter contents into the EEPROM of the JW-21MN. Then start the JW-21MN. After starting operation, the setting value changes to "01(H)."

-Writing time to EEPROM is approximately 0.7 sec. When any error is found for parameter settings, the JW-21MN lights the error code (6F(H)) by the indication lamp. To recover from this condition, see pages 16-2.

-Written contents into the EEPROM are automatically written to the RAM of the JW-21MN when turning ON the power of the PC. At reading, the PC checks BCC and compares BCC check code of the parameter memory address (007776(8)). When an error is found, the JW-21MN lights the error code (6E(H)) by the indication lamp.
