Setting parameters
The parameters are set as follows:
1. The vehicle controller configures the parameters of the JXM-IO-EX30.
2. The vehicle controller saves the settings via index 0x1010 in the EEPROM.
3. The vehicle controller reads the CRC via index 0x4556, subindex 1 and saves this value lo-
cally remanently.
4. After a restart of the JXM-IO-EX30 the vehicle controller compares the locally stored CRC
value with the value in index 0x4556, subindex 1. If the values do not match, parameteriza-
tion must be restarted.
