How to use the Exstreamer 1000 as a PCM STL

How to use the Exstreamer 1000 as a PCM STL (by Dana Puopolo)

The Exstreamer 1000 works great as a linear STL. Here is how to set it up.

First, you need to download and install a small applet to turn the unit into an STL. The name of the file is: custom1.cob. Once you download it, go into the Ex 1000 and click on the update tab The unit will reboot and the update page will appear. Click on the Advanced link. Another page will load. Put the word WEB5 (all caps) in the Link blank, browse to the custom1.cob file and click upload. When told so, power cycle the Ex 1000.

Now, go back into its web page. At the very top of the settings page, you will see a drop down that says Application. Choose the application Custom1, then go all the way to the bottom and click Apply. When the unit reboots, click on the application tab in the red area atop the screen (just below where it says Barix). If you have done everything correctly, you will see the following: FULL DUPLEX INTERCOM WITH AUDIO TUNNEL.

Repeat the above procedure with the other EX 1000.

You need a static IP address (public or private) on ONE end of the connection. If you are using router(s) then ALL routers must have UDP port 3030 forwarded to STATIC LAN IP addresses that you will set on the EX 1000s. If you don’t completely understand what I have written in bold, contact an IT person who does!

For clarity, I will be assuming the following:

1. That both units are on a LAN (the way that most will typically be using them). 2. That in this first case, we will be setting static IP addresses on BOTH units (I will tell you how to set up with one running a dynamic address later). The static IP addresses are 192.168.1.150 (studio) and 192.168.1.151 (transmitter). 3. The router we are using has a subnet of 255.244.255.0 and a gateway of 192.168.1.1.

On unit #1 (the studio end), click the settings tab (red area) and then put the following information in:

In the IP address boxes put 192.168.1.150 In the Subnet tabs put 255.255.255.0 In the gateway tabs put 192.168.1.1 In primary DNS put 4.2.2.1

Go to the bottom of the page and click apply. The unit will reboot.

Now click the Applications tab in the red area

Set the Input source to Line Set the Audio Format tab to either MSB mono or MSB stereo (depending whether your link is mono or stereo) Set the Sampling rate to the desired amount. Your frequency response will be HALF that setting, so for FM use 32 kHz or higher. Set the Max Buffer Level to 6000 Move down to Destination Socket(s). Put the following in there: 192.168.1.151:3030 Make sure the local port is set to 3030. Go to the bottom of the page and click apply.

Unit # 2 (transmitter) is set up pretty much the same way, except for the following:

The IP address on the settings page should be set to 192.168.1.151. The Destination Socket(s) should be set to 192.168.1.150:3030 (Notice that these are basically reversed)

If everything has been done correctly, on the Applications page a green band should appear on both units just below the settings button. It should show the status of the connection as ON.

Now. here’s the way to set up the units if one of them has a dynamic IP address. We’re going to assume that the Studio unit (#1) has the STATIC IP address.

Set up unit #1 as above, EXCEPT for the following: In the Destination Socket(s) line put the following: 0.0.0.0:3030

Set up unit #2 as above, EXCEPT for the following: In the settings tabs, leave zeros in the IP address, Subnet, Gateway and DNS boxes.
