5.9 Change Sensor Address Command
The Change Sensor Address Command allows the sensor address to be changed. The address is
stored in non-volatile EEPROM within the sensor. The H-3531 FlashLite™ will not respond if
the command was invalid, the address was out of range, or the EEPROM programming operation
failed.
