  • Product Family: Billboards
  • Product: 
  • Component: Newly installed modem or First Time Fire-up (FTFU)
  • Control System: 


  • Modem is blocking inbound communication.


  • Modem needs to be configured to allow the ports used by Daktronics equipment to pass through it and reach the Daktronics router that is connected to it.
    • Most modems have a router built into them with a firewall enabled by default which requires settings being changed to allow the connections through.
