4.10. Loading of firmware
e rmware loading process is executed through the service programme.
 See chapter 8.6.8 Updating rmware.
A single le will be distributed, containing the individual rmware for each board. e process consists of rst
sending the le to the main board (CPU) which stores it in a ash drive or repository. Once it has been veried
that the le sent is correct, the service programme will ask the user to conrm the start of the CPU board rmware
updating process. Once the CPU board has been updated, it checks the compatibility of the versions of each of the
boards against those in the repository. If any board has a version that is not compatible with the one in the reposi-
tory, it updates the rmware of that board.
While the rmware le is transmitted with the service programme, the analyser status led will ash and change colour.
All the analyser adjustments are stored in the CPU board memory. When the analyser is initialised, the necessary
adjustments for each board are sent.
NOTE
As a precaution, before performing any operation with the analyser it is advisable to make a
backup copy of the adjustments.
 See chapter 8.6.9 Saving and recovering adjustments.
When the technical service has to carry out a repair and change a board, the technician will start the service pro-
gramme for it to accept the rmware updating process and the adjustments for the new board.
e service programme can also be used to restore the initial adjustment values.
If that process is executed, the technician will have to readjust the analyser in full.
 See chapter 8.6.10 Restoring initial values
