A Technical Application Note from Doppler Systems

1.0 Introduction
Many customers would like to monitor audio from their remote direction finders. This
application note describes how a Barix Instreamer 100 can be used to remotely connect
a Doppler DDF6001 direction finder via a standard TCP/IP Ethernet connection.
2.0 Hardware Connections
Connect the Barix Instreamer RS232 connector to the direction finder using a standard
serial cable. Connect the External Speaker (J6) on the direction finder to either one of
the Line In connections on the Instreamer. Connect the Ethernet cable to a Ethernet
hub or switch. Connect the power adapter to the Instreamer.

3.1 Obtaining the IP Address
Prior to powering the Instreamer connect the network cable to a hub or switch. Plug
headphones or an earphone into the headphone jack of the Instreamer. Get a pencil
and paper and then power up the Instreamer. If you are on a network that has DHCP
support, shortly after powering the device it will announce the IP address of the device.
It there is no DHCP server the Instreamer will search the network for a free address. This
could take as much as 5 minutes. If it finds an available address it will announce over
the headphones. Write down the IP address. If it does not find an available address
press the reset button for 5 seconds to reset the device and assign the default IP
3.2 Configuring the Instreamer
Connect a computer to the network. Launch your internet browser and type in the IP
address obtained above (e.g. The webpage shown below should be
Press the Configuration Button to display the following page
Next press the Audio settings text button and duplicate the settings shown below. Press
Next press the Serial settings text button and duplicate the settings shown below. The
local port is the IP port that you will connect to. You can make this any valid IP port on
the network 1-32767. Write down the IP port that you are going to use and press apply.
Close the browser. The Instreamer is now ready to operate.
3.3 Listening to the Audio
Listening to the audio on the computer requires an audio player capable of receiving
and playing an audio stream. We suggest WinAmp ( It is a free
player and works very well. After you install WinAmp launch it and right click in the title
bar as shown below and select Play ->URL.
Type in the IP address you noted earlier followed by /xstream as shown below.
Click Open and WinAmp will buffer the audio for a short period of time and begin
playing the audio from the receiver connected to the direction finder.
3.4 Configuring BearingTrack
The Instreamer looks just like a network server to BearingTrack so simply set up the site
as you would any Ethernet network connected device. A sample Site Editor setup
window is shown below.
