How To Manually Add AoIP Streams To The JET67 and NET67

How To Manually Add AoIP Streams To The JET67 and NET67

The JET67 Audio Engine and the NET67 card for the Logitek JetStream Plus uses SAP to announce streams to other Livewire and AES67 devices and receive stream announcements from those other Livewire and AES-67 devices.

Some Livewire devices send and receive audio streams that the JET67 and JET67 are compatible with but do not use SAP to announce the streams. This includes the Livewire virtual soundcard driver and satellite receivers used by NPR's Content Depot. Therefore we will need to manually add the stream information to the configuration and upload it to the engine.

Obtain The Config File

Go to JetStream Server and click on the Administration Page.
At the bottom of the page you will see the section for the JetFile.

Click Save to JetFile and place the xls file in C:\Logitek\Configs.
If you use Command Builder, it is important that only the current configuration for the engine be stored in this folder. Do not rename the file and keep backup copies of the same engine's config in C:\Logitek\Configs as this will break Command Builder. When you save a config, we automatically append the date and time to the filename and place a backup copy in C:\Logitek\Configs\Backup so if you need to roll back you can always find backup copies there.

Editing The Config File

When editing the config in Excel, keep the file in .xls format and do not convert to .xlsm.
If you don't own Microsoft Office, you can edit the .xls file in either Libre Office or Open Office. We have not had success using Google Docs.
Click on the Net Sources tab.

Create a Stream Handle. This is the device number used by the audio engine. The stream handle is 200 and higher written in hex and must be unique. Device 200 is written as 0x200. Device 201 is written as 0x201, etc.

Stream Name 1 is the first 8 characters of the surface label (top line). Stream Name 2 is the second 8 characters of the surface label (bottom line). You must enter text in Stream Name 1, Stream Name 2 is optional.

Unique Name is used by Command Builder. Enter text that uniquely identifies the source.

In the Jet Net field enter 83. This is the only valid number to place here; the system uses it to define the stream as a Livewire/AES-67 source. Any other text in the field will mean you won't get audio.

Source Type can be left blank.

Destination IP Address is the multicast IP address of the stream coming from the other device.

Num Channels is the number of channels. For Livewire this MUST be set to 2.

Network Latency should be set as Low.

Save the file in xls (legacy Excel) format.

Upload The Config

In JetStream Server, on the Administration tab, click Read From JetFile and browse to the xls file you just edited. 
You will be warned that uploading this file will interrupt audio. Click Ok. Wait for the upload to complete and the unit to completely reset before proceeding to the JetStream State Page.

On the JET67, you will need to disconnect and reconnect the IP socket on the External Comm page after the reset.
It's a good habit to close Server and restart it after uploading a new config.
When Server starts or when any reset is in progress, wait until you see "JetStream Reset Complete" on the JetStream Log Page before going to the JetStream State page. If you open the State page doing a reset you will truncate the list of sources that the DSP is sending Server and Server won't have all of the information that it needs. If you find that sources are missing, that usually is a sign that the table is truncated; the solution is to close Server, restart it, and wait for the reset to complete before going to the State page.

Once the config is uploaded, the new network streams will be available to be routed to the console.
