This method provides instructions for establishing an OTA server in LAN and then performing firmware upgrades.

2. Run the OTA server in the LAN
  • Run the HFS software on a PC
    • Confirm that the Web service is running on the same network segment IP address as the Hub: [Menu] -> [IP address]-> Select IP

    • Import the latest OTA firmware of the Hub into HFS: [Menu] -> [Add files] -> latest.bin
  • Confirm that the URL of the firmware can be accessed in LAN, for example: (You may enter the URL on another PC or smartphone in LAN via browser to confirm)
3. Perform the upgrade
  • Provide the SyncSign Support with: A) Hub’s SN; B) The available firmware URL(Verified in the steps above).
  • Finally, SyncSign Support will try to upgrade the Hub (Note: the PC where HFS is installed needs to be turned on and running the server, the Hub needs to be kept online).
