KB01641 - Using the Secondary Port on Your AT-OMNI-238


Summary: Using the Secondary Port on Your AT-OMNI-238—

This article explains the secondary port on your AT-OMNI-238.



  • Your network goes down when plugging in the AT-OMNI-238 secondary port.
  • You would like to daisy-chain your AT-OMNI-238s.
  • You would like to use redundancy for your AT-OMNI-238.



  • The secondary port should never be connected to the same network as the primary port.
  • Use Dante Controller to set the secondary network interface to the desired mode.


Changing Secondary Port Behavior with Dante Controller

For Atlona Omnistream Dante devices like the 238 and 232, you will need Dante Controller to configure network and Dante settings on the device.


In Dante Controller, select the network interface you are using for the Omnistream network.

Network interface selection



Your device should show up in the Routing Page.

  • Double-click on the device name (shown in the circle) and the Device View window will open.


 Dante Routing Page



Select Network Config in the Device View Window.

  • Here you can toggle between "Switched" and "Redundant" modes.


Device View Network Config



Switched Mode

Switched mode is for daisy-chaining AT-OMNI-238s. This configuration is useful if you don't have a enough ports on your network switch for each OMNI-238.

  • You may daisy-chain up to 8 units.




Redundant Mode

Redundant Mode is for connecting each OMNI-238 port to a different network switch. Use this configuration for increased system reliability.

  • You cannot connect both ports to the same network, even in redundant mode. This will cause a network loop.
  • If using Dante redundancy, never allow traffic from either network to cross into the other. The intent for this mode is to have a completely separate backup Dante network on separate network equipment for full redundancy.
