  Hello @Selva,

  As you mention a Red flashing NS LED indicates there is an issue with one ore more connections timing out. This typically occurs when there is an issue with the Bus. I recommend checking over the bus and make sure it is configured to spec. Do you have 120ohms at each end of the bus? Is there 24V between 5 and 1?

  The gateway status is indicating the status of the carrier board between the two network boards.
