IONS 3 1 3 Factory reset function The factory reset puts the card back to its initial state as it was delivered from the factory These settings are just a starting condition for the board and new settings applied by the user will still take effect and be stored If a Multicon GYDA is controlling the frame in which the factory reset operation is performed Multicon will see the re insertion of the card in step 4 below as a hot swap event and it will try to write the previously stored settings back to the card There are two ways to avoid this mechanism The safest and easiest way is to keep the Multicon GYDA pulled out during the factory reset procedure The next best thing is to select the Manual mode in step 3 which will effectively prevent the card from acknowledging the commands sent from Multicon in step 4 After 30 seconds the Multicon settings will instead have been updated from the card settings some of which may now have been overridden by the DIP switches and then the card can be unplugged once more and returned to Gyda mode The factory reset is a four step procedure 1 Pull the main card out of the frame and set the two DIPs labelled F RESET and OVR to their On positions 2 Re insert the card into the frame The Status LED will now be a permanent orange colour No further waiting is needed after seeing the Status LED lit up orange 3 Pull the card out of the frame again and return the DIP F RESET to its Off posit
