How To Set Up Dante On The JetStream Plus

How To Set Up Dante On The JetStream Plus

General Notes

  • Connect Audio Net 1 on the JSP-DSP card to the Dante Network
  • The default out of the box is that the Dante networking module is expecting to be issued an IP address by a DHCP server.
  • All Dante devices need to be on the same subnet. If you have primary and secondary Dante networks, you must use a different subnet for the secondary than the primary
  • Note that since primary and secondary requires a different subnet, if you don’t have a DHCP server and you don’t set static IP addresses, using AutoIP will throw errors when you plug in a secondary network connection.
  • You’ll want Dante Controller to be running on a computer that’s connected to the same LAN and within the same subnet as Audio Net 1.
  • As of now, Logitek does not support secondary Dante networks.

JetStream Server Notes

  • On the admin page is a place to enter IP addresses for Audio Net 1 and Audio Net 2. Audio Net 1 is hooked to the device that does network discovery for the Logitek system. Audio Net 2 is hooked to the Dante network controller.
  • While you are only plugging in one network cable to the card, there’s an Ethernet switch built into our card that’s connecting the two network interfaces inside to the one cable.
  • The Logitek discovery controller in Audio Net 1 can get an address via DHCP or it can get a static address. To assign a static address, enter the address in the Audio Net 1 field. To assign a DHCP address, enter 0.0.0.0 in the Audio Net 1 field.
  • The Dante network controller in Audio Net 2 can either get an address via DHCP or it can get a static address. To assign a static address, enter the address in the Audio Net 2 field. To use DHCP, enter 0.0.0.1 in the Audio Net 2 field
  • While most broadcasters prefer using static IP addresses, Dante assumes that everyone uses DHCP and many Dante devices will fight you when you try to set a static address. Make your life easier by using DHCP.
  • While you can use AutoIP to let the network cards make up their own addresses, if you are using primary and secondary networking, using AutoIP on both will cause this to fail because both networks can’t be in the same subnet. Pro tip: use network switches that have DHCP servers built in to run your primary and secondary Dante network and set them to different subnets.
  • After you change any of these settings you must reboot the Dante controller for the changes to take effect. The easiest way to do this is either press the DSP Reset button on the DSP card or click Hardware Reset in JetStream Server on the JetStream Log page.
  • You must have Audio Net 1, Audio Net 2, and all Dante devices set up on the same subnet before you begin configuring network inputs and outputs in Logitek, otherwise we’ll never see what you’ve done in Dante controller.

The Logitek NET-67 card on the JetStream Plus only supports one Dante network, so connect us to your primary Dante network.

Managing Dante Inputs on the JetStream

Key things to remember:

  • In Dante, whenever you change the name of a source, Dante deletes the stream and creates a new one. This means you should delete the existing entry in JetSet (web browser config, Network IP page, streams from network tab) or JetStream Server (System Info, Streams From Network) before you rename it in Dante.
  • You have to name the stream in Dante Controller in order for the JetStream to know it is there. As soon as you name it in Dante Controller, it sends a message to JetStream Server to create a network source.
  • A key difference between how Dante does things and how we do things is stereo sources. In Logitek, a stereo source is a single device number that encompasses both channels. In Dante, every channel is handled individually, so we must go through extra steps to make the two Dante devices act as a single Logitek device. We will need to edit the left channel source in the Logitek editor to create a flow in Dante to get left and right when we route the source on the console.
  • In the Logitek GUI (both JetStream Server and the JetSet web GUI, it is normal for Dante sources to appear in red. Ignore the part about sources in red not being available. That applies only to Logitek network sources, not Dante sources.

Create A Dante Output

Note: In the Dante world, every input is defined as channel label@device name. If you would like to change the default names of your Dante devices, do it in Dante controller before you start labeling channels and creating routes; when you change the label all routes throughout the network are destroyed.

Go to Dante Controller and click on Device Info. Double-click on the device. Another window appears. Click on the Transmit tab. Click in the Channel Label box. Type in the source name. Logitek will display the first 16 characters you enter here. Hit enter when done. When you hit enter, the Dante network module will send this immediately to Logitek.

Tip: when entering stereo sources, for the left channel type in the source name and for the right channel type in source name R. That way you can tell which is left and right

Now that you’ve done this, the channels have been sent to Logitek. If we need to combine channels for stereo sources, do the following: Open the web browser on the JetStream, log in, and click on the Network IO button. Click on the Sources From Network tab. Click to edit the source that’s the left channel. In the UDP stop string, enter chan=2 (all lowercase, no spaces). Ensure there is not a space between the beginning of the field and the c of chan. Click Upload to JetStream. Repeat for all stereo pairs. When complete, go to JetStream Server and click refresh. 

In the Logitek JetSet, you will assign only the left channel source of a stereo pair to the surface. When we make the route, we’ll see the chan=2 text and know to ask Dante to make a flow to combine the left and right channels and you will get stereo audio.

If the source in question is something that you usually sum left and right together, edit the left channel source in Logitek JetSet and set the mode to Mono. Click upload to JetStream. Do a refresh. (If you remember you’ll need this for certain sources like remotes and servers, you can set the mode at the same time that you are doing the chan=2.

Sending A Stereo Output From Logitek To Dante

  1. Open JetSet (the web browser on the JetStream) and log in
  2. Go to Network IO. You will be on the Sources to Network tab. Click Add New Output.
  3. Enter the Surface Label. This will be transmitted to the other Dante devices. You have 16 characters (2 fields of 8)
  4. In the unique name field, the first 2 characters must be D| The | character on most keyboards is shift + backslash (\). After the | character you can label the source so you know what it is. It’s easier to read if you put a dash or a space after the |. Just don’t forget the first 2 characters must be D|
  5. Set the dropdown for the Default Source to the audio you wish to route to Dante.
  6. Click Upload to JetStream.
What happens here is we look for the D| to know this is information we need to send to the Dante networking module inside the engine. Any network sources without the D| are sent to a different Ethernet card to be processed using a Logitek AoIP protocol.

Sending A Mono Output From Logitek To Dante

This is almost exactly the same as a stereo. It’s a long story as to why we have to jump through this hoop…

  1. Open the JetSet web browser and log in
  2. Click on Network IO. You will be on the Outputs to Netowrk tab. Click Add New Output.
  3. Enter the Surface Label information and change the number of channels to 1. DO NOT DO ANYTHING ELSE.
  4. Click Upload to Jetstream.
  5. Now click on the output you just created. Set the Unique Name (including the D| as explained above in the stereo section). Set the Default Source. Click Upload to JetStream again to finish.
