This applies to UCM/USB, UCM/ETH02 and UCM/232 with firmware 6.080 and above
The U2 EEPROM on the UCM can be used to save the Comfort configuration
To read the configuration from Comfort and save in the U2 EEPROM on the UCM, press and HOLD the UPLOAD button on the UCM for 2 seconds, until the BUSY1 (RED) LED starts blinking. This takes about 2 minutes. When the operation is complete, the BUSY1 LED wlll stop blinking and turn off, while the Green RDY led will be on.
To write the saved configuration in the UCM U2 EEPROM to Comfort, press and hold the DOWNLOAD button for at least 2 seconds until the BUSY2 LED starts blinking. This takes about 1 minute. When the operation is complete, the BUSY2 LED wlll stop blinking and turn off, while the Green RDY led will be on. This works only if the File system in the U2 EEPROM matches that in Comfort, ie the 2 configurations are compatible. This prevents invalid configuration from being written to Comfort
This method can be used to save a working Comfort configuration including all programming and user codes. If user codes have been forgotten, then pressing the DOWNLOAD button will restore the saved configuration including user codes to Comfort. Hence once the comfort configuration has been fully tested, use the UPLOAD button to save the configuration to the UCM
