How do I configure redundancy for a display using a NovaStar sender box?


  • How to add redundancy (hot backup) for displays using a NovaStar Sender Box?


  • Product Family: Sender Box
  • Product: Nova MCTRL 600, Nova MCTRL 660, NovaStar VX4S, NovaStar brand sender box and receiver cards
  • Components: NovaLCT-Mars
  • Control System: Market Standard or Limited Compliance using transmit common/open protocol
    • This includes but not limited to DVN-4003, Dragon Sticks, J Series, JVX, NPN-4200/4400, NPN-5200/ 5400, U Series, Q Series, QVN, Z Series, and ZPN.


There are 2 modes of redundancy.  One mode uses another port on the same sender box or a second sender box. 

Note: In the two-sender box scenario the send boxes must be cascaded together on a single USB chain.

Before configuration, please make sure the last receiver card is connected back to the sender box

    Local System Information v5.1.0.png
  2. At sending card, click add in redundancy.
  3. Set the sender box number and port number of the primary on the left-hand side and the corresponding backup on the right-hand side.
    1. See the single sender box example below: Single sender box example (Port 1=P Port 2=B)
    2. This would feed the last receiver card back to sender box, forming a loop within sender box and all receiver cards. 

  4. Each set of ports must be added to the redundancy table individually.

  5. After all entries are added, close the settings box. Click the Send button below the redundancy table.  Then press the Save button at the bottom of the page.redundancy 4.png
