8. Parameter Modification Procedure
Sometimes it may be necessary to change a batch of parameters to reconfigure a panel. The factory will issue a
new “json” file that contains the modified settings. Follow this procedure to reconfigure the Ethos Two.
8.1. Lift Parameter Modification
To perform this procedure you will need a PC with USB micro lead and / or an SD card reader.
The Lift board searches for a JSON file named “Modification_CSVX.XX_XX.json” on the SD Card. Ensure only one
JSON file of this type is stored on the SD Card’s root directory before following this procedure.
Press: Toolbox → Debug Screens → Processor Status
Check “EA State” says: Good.
Press: Settings → View Changes
Verify parameters. A parameter problem (or absent lift processor SD1 Card) will be reported as an “Unable to fetch
differences.” Ensure lift is unoccupied and ready to be taken out of service. Take panel off LAR and TTR (hit the
STOP push). Connect a USB lead from the PC to lift card (J16, LHS of board). Seize the USB port, by pressing the
SD1 Connect button in the toolbox.
Press: Toolbox → Connect SD1
The Ethos Two unit should now appear as a USB Flash Drive on the connected PC
Backup the entire SD card to your local machine. Copy the factory, user and backup “*.json” files and any
binary files located on the SD card’s root into another directory on the SD Card e.g. “\Old\RevX.XX”.
Copy the new JSON file onto the SD card root directory. The SD card’s root directory must contain a factory
“factory_CSVX.XX_XX.json” file and preferably should also contain user and backup files, as well as the
new modification JSON file.
Safely eject the USB device from the laptop, and tap “Disconnect SD1” in the Toolbox menu. Remove the USB lead.
Press: Settings → Modify Settings
The Ethos Two unit will now proceed to import the modified parameters by firstly overwriting the current backup
JSON file with the current user JSON file, then editing the current user JSON file with the required changes.
Press: Settings → View Changes
Use View Changes to verify parameters have been migrated successfully. A parameter problem (or absent lift
processor SD1 Card) will be reported as an “Unable to fetch differences” message in this screen.
