INFO
Loading the settings from the EEPROM
During bootup, the last saved settings are automatically loaded.
During a firmware update, the settings may be reset to the default values.
Setting parameters
The parameters are set as follows:
1. The vehicle controller configures the parameters of the JXM-IO-EW30-G27.
2. The vehicle controller stores the settings via index 0x1010 in the EEPROM.
3. The vehicle controller reads the CRC via index 0x4556, subindex 1 and saves this value
locally in a remanent memory.
4. After a restart of the JXM-IO-EW30-G27 the vehicle controller compares the locally
stored CRC value with the value in index 0x4556, subindex 1. If the values do not
match, parameterization must be restarted.
INFO
Activating the Changes
The changes to the indices 0x1010 and 0x1011 only become active after a
restart.
