1 Introduction
1.1 About the “Instreamer” firmware
The “Instreamer” firmware is designed to serve as a versatile, network-enabled analog and digital audio-to-
Ethernet converter for commercial audio distribution.
The “Instreamer” firmware converts audio from any analog or digital device into G.711 (8 bit), PCM (16 bit) or high-quality MP3 streams. The audio is encoded in realtime, and the generated audio stream can be distributed,
via an IP -based network or the Internet, to one or more
receivers or Shoutcast / Icecast-servers.
Barix devices running the “Instreamer” firmware can be easily managed via a web browser interface using PCs, web pads, PDAs or other web-enabled devices. SNMP remote monitoring capabilities allow for building a manageable distributed audio network. With serial and
Ethernet control APIs, open IP -standards, and the
standard encoding formats, the device can also be integrated with other components, controlled by automation systems, or used with Barix Exstreamers to create more flexible, more cost-effective distributed audio systems.
The built-in serial interface allows data to be relayed to another Barix device, a PC or a server using the “Serial
Gateway” functionality of the “Instreamer” firmware.
With an optional stick-on transmitter, additional IRenabled devices can be remote controlled via the network connection, enabling users to control their audio sources without being in the same location as the device.

3.1 Network settings
This chapter explains how to adjust the network settings of the Barix device.
IP Address
We recommend that you set a Static IP address. With a
static (permanent) IP address the device does not have to
get a new IP address at power on or reboot.
Enter the 4 values of the desired static IP address e.g.:
• “192.168.0.12” for an internal LAN
Attention: Make sure that you enter a free IP address.
The device will check this and will not be available until the device using the same IP is disconnected or switched
off. The command Ping can be used to ensure that a
specific IP address is unused (i.e. No reply).
The automatic discovery functions are not executed if a
Enter 4 zeroes to enable it:
• “0.0.0.0” for automatic discovery (Discovery order:
BOOTP, DHCP , IPzator , AutoIP)
To enable automatic discovery but disable certain IP discovery functions set all but the third value to zero.
For each function you want to disable add the value from the table below:
Device Configuration
17
User Manual “Instreamer“ - V3.01 - Not released
• “0.0.1.0” to disable AutoIP
• “0.0.4.0” to disable BOOTP
• “0.0.8.0” to disable IPzator
Examples:
• “0.0.3.0” disables AutoIP and DHCP
• “0.0.11.0” disables all but BOOTP
Attention: “0.0.15.0” disables all discovery functions
which locks you out unless you reset the device to factory defaults by pressing the reset button for about 10 seconds.
Netmask
Enter the 4 values of the desired Netmask e.g.:
• “0.0.0.0” for a default Netmask depending on the IP
Address used
• “255.255.255.0” for a C class network
Note: Try first the Netmask your PC is set to or ask
your Network Administrator.
Gateway IP Address
A correct setting of the Gateway IP address is needed to stream to the Internet or to destinations outside your local network (LAN).
Enter the 4 values of the desired Gateway IP address e.g.:
• "0.0.0.0" for no Gateway or automatic discovery
• "192.168.0.1" for a Gateway in a LAN
Note: If you have set the devices IP address to automatic
discovery and your server or router has issued an IP address then most probably it also has supplied a valid
Gateway address, “0.0.0.0” will then work fine.
If you have set a Static IP address then you will need to

Advanced Encoder Settings
These following settings are for advanced users only.
Detailed information about the Encoder Settings can be found in the Micronas MAS3587 MP3 encoder data sheet.
A/D amplifier gain
Choose the desired gain (“-3” up to “19.5” dB) for the line input A/D amplifier.
Note: The line input sensitivity has changed from 2 Volts
peek to peek on legacy devices to 4 Volts peek to peek on the new “Instreamer 100” (less sensitive).
MP3 Frame CRC
If set to “enable”, the encoder will include the CRC-16 to each MP3 frame.
MP3 Bitreservoir Mode
The “Bitreservoir” is used to compensate the differences between the predefined frame sizes. If set to “used”, the encoder will use the bitreservoir. Leave the setting to
“kept empty” if you use RTP streaming or need low latency on the transmission.
MP3 Channel Mode Extension
“Enable” or “disable” the MS-Stereo encoding (for stereo only). When set to “disable MS-Stereo encoding” only mono will be encoded and therefore the bandwidth used is minimized.
MP3 Copyright Protection
“Enable” or “disable” the copyright protection bit in the
MP3 stream.

Own Name
You can enter the name of the Barix Instreamer here.
This name will be returned when using the DISCOVER command (see technical documentation).
Streaming mode
Streaming is started depending on the selected operating mode:
• “send always” will stream always
• “send on CTS” will stream if the SEND button
(command) is pressed or CTS (Pin 8 Serial connector) is connected to a positive supply (9VDC, Pin 4 Serial connector)
• “send on Level” will stream if the incoming audio signal is above the Trigger level (see section below)
Trigger level
The “Trigger level” is only used when Streaming mode is set “send on Level”.
Select a value between 0 and 32767.
Open the Device status page and look for the Input peak value to get a hint for the trigger value. This page refreshes itself every few seconds.
Pre Trigger Start
Pre Trigger Start can be adjusted to prevent a cut off when audio should be sent earlier than detected. It defines the amount of time that will be streamed before the actual trigger occurred. This feature is most useful when used in combination with the send on level feature.
Post Trigger Play
Post Trigger Play can be adjusted to prevent a cut off when audio should be sent longer than detected. It defines the amount of time that the device will continue streaming after the actual trigger has been cleared. This feature is most useful when used in combination with the send on level feature.
Device Configuration
25
User Manual “Instreamer“ - V3.01 - Not released
Buffer Underrun Mode (TCP)
The Buffer Underrun Mode (TCP) defines the action if a
TCP stream is slower than the real stream from the encoder. In this case the output streaming buffer underruns and cannot hold older data any more. The device can then “disconnect” the TCP connection or it can ”skip” the stream directly to the encoder stream without disconnecting TCP.
Streaming Strategy
The Streaming Strategy defines how a packet is build and sent. On “lowest latency” the encoded data will be sent directly after the encoding. On “optimal package” the packet will be filled up before sending.
UDP Tx Source Port
This setting is only used with a custom software application. Enter the used source port number for a
UDP stream (between 0 and 65535). When set to 0 the source port is set to the same port as selected in the destination port (in section Stream to). If destination is set to “origin source” the UDP Receiver Port is used.
Radio Path
Enter a radio path to listen to the transmitted stream of this Barix Instreamer using a device that is able to play
MP3 radio stations (also PC software like WinAmp).
The URL to connect is http://x.x.x.x/p where
x.x.x.x is the IP address of this device and /p is this
Radio path.
Example: http://192.168.0.24/xstream

Stream to
There are up to 8 destinations to stream to. Each one can be directed to a device, or a multi- or broadcast address
(destination connection types) or be set up as a listener waiting for a connection to be initiated by the other side
(listener connection types). Each entry has its own IP address and Port. See the following sections on how to set the “Stream to” entries.
“Stream to” Considerations
The choice of settings to distribute the stream to other devices depends on your environment and desired functionality.
If the stream should be reliably received by just a few devices (up to 8) “raw TCP” can be used since lost packets are retransmitted automatically. If you encounter too many audio blanks (hiccups) then we recommend using RTP since lost packets are replaced by the
“Streaming client” firmware in the receiving “Exstreamer” device. This type is to be favored when the stream has to pass a number of routers (WAN or Internet) as RTP is resilient to packet delays.
If the stream is intended to be received by many devices we recommend to use UDP broadcast as long as all devices are on the LAN as broadcast is not be able to pass over a WAN.
If your receivers are behind routers using NAT (network address translation) we recommend to use BRTP which can use port 80 and no change to the router is required.
Only the router on the “Instreamer” side has to have an open port 80 forwarding requests to the “Instreamer”.
If your network infrastructure is capable of multicasting use multicast (instead of multiple unicasts) to reduce the traffic generated.
A mix of all the above is possible as each of the 8 destinations allow the individual choice of the connection type

(except for the types “BRTP” and “SIP” which are only available with the first entry).
Stream to “Disabled” entry
Set the connection type to “not used” to disable an entry.
The IP and Port can be left as is as they are as they do not matter on a disabled entry.
Stream to “Internet Radio” entry
Set the connection type to “Internet Radio” radio server for a single client (default). The IP “0.0.0.0” will act as a
TCP listener (HTTP) waiting for a connection on the port selected under “Port#” (0=80). See also section
Radio Path for additional configuration details.
Limitation: Even though eight entries can be
configured only six concurrent radio servers are supported.
Stream to “RTP” entry
Set the connection type to “RTP” (Real Time Protocol) for an RTP destination. The IP “0.0.0.0” will broadcast
(UDP) on the subnet (e.g. "192.168.0.255") on the port selected under “Port#” (e.g. 4040), enter an IP for a UDP unicast destination (e.g. “192.168.0.11).
Stream to “BRTP” entry
Set the connection type to “BRTP” (Barix Real Time
Protocol) for a BRTP server (up to 32 clients). The IP

Set the connection type to “Shoutcast source” to connect (TCP) to a single Shoutcast server. Enter IP and port of the Shoutcast server for the device to act as a
Shoutcast source. When authentication is needed please
read also section Ice/Shoutcast (Security settings).
The IP “0.0.0.0” will let the Instreamer act as a Shoutcast server itself waiting for a connection on the port selected under “Port#”. The function is then limited to a single client (a media player like Winamp) and only one entry is allowed to be set to Shoutcast server (IP 0.0.0.0).

SNMP settings
SNMP settings are located in the streaming section and are for advanced users only. Different SNMP traps can be generated depending on the state of the Barix Instreamer.
The traps are triggered according to specific audio values as following:
Trap Target IP Address
Enter the IP address of the SNMP trap destination.
Low Audio Level
Define the low audio level for the trap generation. A trap will be generated as soon as the audio level goes below this value (and the “Silence timeout” has run out).
High Audio Level
Define the high audio level for the trap generation. A trap will be generated as soon as the audio level goes above this value.
Trap Repeat
Define the repeat interval for the SNMP trap sending.
The trap will be repeated if the values are still according to the defined trap stages after this repeat time.
Silence Timeout
Define the time that has to run out before a trap is sent when the audio level is below the defined low audio value.

Local port
Defines the port on which the serial port can be accessed for serial gateway application. Only when “Local port” is set to "0" the serial port can be used as a command interface.
If the active serial gateway is enabled and the "Local port" is set to a value then this will be the source port of the
TCP connection. On "0" a random source port is used.
Destination IP
To have this device actively establish a serial gateway select the destination IP address to the device where the serial data will be transmitted to (and received from).
Select "0.0.0.0" when the serial port is used only locally.
Destination port
Defines the port for the active serial gateway function
(see destination IP).
Notes: Both settings, "Destination IP" and "Destination
port" have to be set to enable the gateway function.
When Serial Gateway is activated the serial port cannot be used as a command interface. This also applies for the device on the other side of the "Serial Gateway".
To establish a "Serial Gateway" between two devices only one device has to be activated. In other words: Only one device will need a Gateway destination IP and Port set.
The other side will only need the parameter “Local port” to be set to the same value as the above “Destination port”. On power up the active device will connect to the selected device and will try to reconnect automatically in case of a lost connection. This allows you to establish a serial connection between the attached devices on each side over LAN or WAN.

6 Updating the device
Barix preloads all Instreamer family devices with firmware which is current at the day of production.
Barix constantly enhances the capabilities and functions and recommends to keep the firmware on the Barix
Instreamer up-to-date.
Barix recommends the use of the “Serial Rescue” method to update the firmware.
For the alternative method “Web Update” the
“Web server port” has to be set to “0” or “80” to work properly (0 will set the default port “80”).
If the web update is interrupted during the process
(power or network loss) the device might become unreachable. In that case the “Serial Rescue” procedure is the only remedy. Please keep that in mind when planning a remote update.
6.1 Downloading the latest firmware
To download the latest “Instreamer” firmware version please visit www.barix.com
.
• In the menu on the left side click on “downloads”
• In the center column select select the appropriate device (Instreamer or Instreamer 100) and click on the name of the device.
• Click in the section “Firmware” on the “Instreamer
Update Kit” link to download it.
• Save the ZIP file and unpack it to a local drive.
Read the "_readme1st.txt" file for detailed instructions.

6.2 Serial Rescue
The “Serial Rescue” procedure loads the entire firmware and resets the device to factory default settings (current configuration is overwritten).
It is therefore helpful to note the current setting. Printing out the “status” page is the quickest way as the page contains all configuration parameters.
Open your web browser and type in the IP address of the
Barix device in the URL field followed by “/status” and hit the “Enter” key.
• Example: “192.168.0.12/status”
To apply the Rescue using the supplied serial cross cable and a PC running Windows 2000, Windows XP or Linux follow the steps in the “_readme1st.txt” carefully as there are several different applications (batch files) to be started depending on the Barix hardware (new or legacy) and the PCs COM port number used.
Calculate approximately 2 minutes to complete the
“Serial Rescue” procedure. After a successful rescue the device is ready for configuration according to your needs
(see chapter 3 Device Configuration ).
6.3 Web Update
To apply the “Web Update” procedure you will need a standard web browser and the IP address of the device
(announced by the SonicIP feature).
Make sure that the “Web server port” is set to “80” before starting the procedure.
Calculate approximately 2 minutes to complete the
“Web Update” procedure.

DHCP
IP
IPzator
MAC address
Netmask
Ping
Short for Dynamic Host Configuration Protocol, a protocol used to assign an IP address to a device connected to a Network.
Short for Internet Protocol, the IP is an address of a computer or other network device on a network using IP or TCP/IP. Every device on an IP-based network requires an IP address to identify its location or address on the network. Example: 192.168.2.10
Barix IPzator™ technology is designed for the purpose that the Barix device can create its own IP address according to the network structure in case it can’t
receive one from your network. If DHCP, AUTOIP or
BOOTP fail, IPzator will create an IP address within the subnet and test it. If the address works and is not being used by another device on the network, it will give the address to the Barix device.
Abbreviation for Medium Access Control, a MAC is a unique address number formatted in hexadecimal format and given to each computer and/or network device on a computer network. Because a MAC address is a unique address a computer network will not have the same MAC address assigned to more than one computer or network device. Example: A1:B2:C3:D4:E5:F6
A number used to identify a sub network so that an IP address can be shared on a LAN (Local Area Network).
A mask is used to determine what subnet an IP address belongs to. An IP address has two components, the network address and the host address. For example, consider the IP address 150.215.17.009. Assuming this is part of a Class B network, the first two numbers (150.2) represent the Class B network address, and the second two numbers (.017.009) identify a particular host on this network. The Netmask would then be 255.255.0.0 .
Ping is a basic Internet program that lets you verify that a particular IP address exists and can accept requests.

SonicIP
Static IP
Telnet
Example: ping 192.168.2.10
Barix SonicIP ® technology is designed to vocally announce the Barix devices current IP address. This makes it easier and faster to obtain the necessary network information. To make use of SonicIP plug in the included earphone into RCA audio out, connect the network and plug in the power supply. It will announce the address over the earphones right after power up.
A Static IP is a fixed IP address that you assign manually to a device on the network. It remains valid until you disable it.
Telnet is a user command and an underlying TCP/IP protocol for accessing remote computers. On the Web,
HTTP and FTP protocols allow you to request specific files from remote computers, but not to actually be logged on as a user of that computer. With Telnet, you log on as a regular user with whatever privileges you may have been granted to the specific application and data on that computer. Example: telnet 192.168.2.10
