The sending box/card is not recognizing the receiver cards.


You can use the NovaS​tar software to identify the receiver cards that are not communicating the sending box/card.  Send configuration parameters to each receiver card.   If are not able to send the parameters to the receiver card, you will know that the receiver card is not communicating.

  1. Make sure power is going to the cards
    1. The cards in the cabinet should have a solid red light and a green flashing light. (This may not be an option for NPP displays.) 
  2. Check the cat 6 cable from the sending card to the receiver card. Swap this out for a new cable if necessary.
