1 Introduction

1.1 About the Annuncicom

Congratulations on the purchase of your Annuncicom from Barix AG.

What exactly is the Annuncicom? The Annuncicom is a network-based intercom, featuring fast setup, operation over existing network connections, flexible use and easy reconfiguration.

The Annuncicom can work with other Annuncicom devices in a standalone configuration or can seamlessly inter-operate with IT equipment like PCs.

Up to two buttons (Talk & Door, Talk & Emergency etc) plus relay output interface are available, which allow the use of the Annuncicom in talk-back and door entry solutions.

Applications include

Door intercom, talking over TCP/IP networks
Alarming in public infrastructure, for example airports
Remote paging connectivity via networks
Residential intercom with network connectivity

Automatic announcement systems

Each device can be configured to directly talk to up to 8 targets, via broadcast, or with the last calling station.

An unlimited number of communication partners can be selected via web browser or serial interface (directory connection).

The Annuncicom is the ideal solution to monitor entrances and to provide intercom and alarming functionality in large residential, commercial and military building complexes like airports, office buildings, malls and residential housing areas. It can also be used along highways or in tunnels to provide IP based intercom capabilities.

No need for extra wiring when using existing network infrastructure or operating wireless, hence saving implementation time and costs. Using only standard TCP/IP protocols, connecting remote facilities is simple, and no changes to the existing WAN infrastructure are necessary.

1.2 Features

Semi duplex two-way communication using mono audio streams.
Choice of MPEG, G.711 and PCM audio formats.
10/100 Mbit Ethernet connection
Two button input (e.g. Talk & Door) plus relay output interface
Controllable via a standard web browser (PC, PDA, Web tablet) or via a serial port
Line in, Line out, built in amplifiers for microphone and speaker
Features SonicIP® and IPzator™ technology
Easy integration into existing IT and intercom infrastructure

3.2.1 Configuration choices

From software version 4.06 the configuration is simplified to the following options:

➢ Basic Settings
Allowing the configuration of a simple use case, typically with two devices
➢ Advanced Settings
Allowing the configuration of all the parameters except the routing tables
➢ Table Settings
Allowing the configuration of all 64 table entries.

Within each of these 3 configuration groups, any parameters can be changed on multiple pages and applied once. This is an improvement over previous versions of the software which required parameters to be saved for every page. Use the “Apply” button to save all changes made in the current group. Use “Cancel” to cancel all changes.

3.2.2 Parameters

If Advanced or Table Settings is chosen a further menu choice is available to select a group of parameters. The menu selection is highlighted.

3.2.3 Help

Help is provided to configure each parameter. The help information is updated in parallel with the parameter menu selection.

3.3 Basic Settings

The Basic Settings allow the most common parameters to be set. For a description of the parameters refer to sections 3.4 Advanced Settings and 3.5 Table Settings below.

3.4 Advanced Settings

3.4.1 Network settings

Here a Static IP address can be configured for the device. This is recommended so that the device does not have to obtain an IP address on every power-up.

Use SonicIP®

If set to "yes", the device will announce its IP address over the audio output. Default: "yes"

IP Address

Enter the 4 values of the desired device IP address e.g.: "0.0.0.0" for automatic discovery (DHCP/Bootp, IPzator, AutoIP), "192.168.0.12" for an internal LAN Default: "0.0.0.0"

Netmask

Enter the 4 values of the desired Static IP 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 Default: "255.255.255.0"

Gateway IP Address

Enter the 4 values of the desired Gateway IP address e.g.: "0.0.0.0" for no Gateway, "192.168.0.1" for a the LAN Gateway. Note: The Gateway has to be set only when connecting to other devices over the WAN (through a router).
Default: "0.0.0.0"

DHCP Host Name

Name of the device sent in a DHCP request. If left empty, a name based on the device's MAC address is generated automatically. Enter up to 15 Characters.

Type of Service/DSCP

ToS value used for TCP and UDP streaming.
DSCP(Differentiated Service Code Point) supersedes IP4 ToS value and uses the same byte.
Check for DSCP services available in your network to set this value. Valid values are 0-63.
Default value is 0.

3.4.2 Settings

These settings adjust the audio input and output

Input section

Input source

Choose the desired input source.
All input sources except "Line stereo" are mono. If you are using an Annuncicom 200 a further option is available to select the SUB connector for Aiphone use. If this is selected the audio output will also be directed to the SUB interface. NOTE: Aiphone panels have a "ring" button which when pressed produces a signal on the SUB interface. This signal is used to trigger digital input 0 on the Annuncicom. However, this signal may also be triggered by audio input and is, therefore, filtered out by the FW. For this filter to be effective, Aiphone panels should only be connected to the SUB interface if the SUB interface is selected as an input source.
Default setting is "Mic".

Speaker Also As Microphone

A speaker can be wired to an Annuncicom so that it can also be used as a microphone. In this case connect the speaker between (+) (A5) and ground (A3 or 4) instead of between (+) and (-) and connect (+) to the Microphone Input (A1). You will find the pin outs in the Annuncicom Quick Install guides.
For proper operation of the device this feature should only be selected if the speaker is wired as described.

Microphone gain

Choose the desired gain ("21" - "43.5" dB) for the microphone.
Default setting is "21" dB.

A/D amplifier gain

Choose the desired gain ("-3" - "19.5" dB) for the A/D amplifier.

Loop Input to Output

Choose "Yes" to hear the attached input on the local Line Out (For testing only, feedback may occur when using a speaker).
Default setting is "No".

Encoding

Choose between different encoding types (audio compression) and sampling frequencies.
From "MPEG1 / 48 kHz" down to "MPEG2 / 16 kHz" and "uLaw", "aLaw" or "PCM" at 8 or 24 kHz. Default setting is "MPEG2 / 22.5 kHz".

MPEG Encoding Quality (MP3 only)

Choose between "0 lowest" and "7 highest" in steps of 1.
The Encoder Quality table below shows the average bit rate in kbit/s for the quality settings and sampling frequencies in kHz. Default setting is "0 lowest".

Output Section

Volume

Choose between "0"% and "100"% in 5% steps.
Default: "50"%

Bass

Choose between "-10" and "10".
Default: "0"

Treble

Choose between "-10" and "10".
Default: "0"

Loudness Level

Choose between "0" and "20".
Default: "20"

Output Mode

Choose one of the "Mono", "Stereo" or "Bridge" settings.
The "Mono" mode produces a monophonic output signal out of both channels.
The "Stereo" mode lets both channels through.
The "Bridge" mode creates a mono differential left/right signal for connecting a single double-impedance speaker as a bridge between left and right channel.

Note: The "Stereo" and "Bridge" settings apply for stereo hardware only. The output mode should correspond to the audio encoding used. The MPEG encoding is stereo, whereas uLaw, aLaw and PCM can transmit only monophonic signal.

Advanced Encoder Settings

MP3 Frame CRC

If set to "enable", the encoder will include the CRC-16 in each MP3 frame.
Default setting is "enable".

MP3 Bitreservoir Mode

The Bit reservoir is used to compensate the differences between the predefined frame sizes. If set to "used", the encoder will use the bit reservoir.
Default setting is "kept empty”

MP3 Copyright Protection

"Enable" or "disable" the copyright protection bit in the MP3 bitstream.
Default setting is "enable".

MP3 Stream Type

Select between a "copy" or an "original" bitstream in order to set the appropriate bit in the MP3 bitstream.
Default setting is "copy".

MP3 Emphasis

Select emphasis "none", "50/15 us" or "CCITT J.17".
Default setting is "none".

Supervision (Annuncicom 155 only)

Speaker Supervision

On the Annuncicom 155 the attached loudspeaker can be supervised by the hardware. The supervision is done using a 11Hz tone injected into the signal. Status of the speaker is then displayed on the device's home page.
Configure the supervision:

permanently off - to disable the 11Hz tone and speaker monitoring
permanently on - to enable the speaker monitoring permanently
periodic - to enable the speaker monitoring in 1-minute intervals (10s tone pulses)

Default: "permanently off".

3.4.3 Streaming settings

These settings adjust the streaming mode, parameters and destinations.

Own Name

You can enter the name of the Annuncicom here. This name will be returned when using the DISCOVER command (see technical documentation)
Default setting is "".

Streaming mode

"send always" will stream always
"send on TALK" will stream if the TALK button (command) is pressed
"send on Level" will stream if the incoming audio signal is above the Trigger level
"auto answer" will stream back for the Post Trigger Play duration after a stream has been received
"receive only" can receive a stream but will never send one
Default setting is "send on TALK".

Trigger level

Is only used when Streaming mode is "on Level".
Set to 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.
Default setting is "1000".

Pre Trigger Start

Pre Trigger Start can be adjusted to prevent cut offs when audio should be sent earlier than detected. It defines the duration of the stream used before the actual trigger occurred.
This feature is normally used in combination with the send on level feature. However, this parameter has a further use, to determine the receive stream strategy. If 0, a minimum audio delay strategy is chosen at the receive side. Otherwise a minimum audio loss strategy is chosen.
Default setting is "0" milliseconds.

Post Trigger Play

Post Trigger Play can be adjusted to prevent cut offs 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 normally used with the send on level feature. When Streaming mode is set to "auto answer" this defines the duration the device will stream back after a stream has been received.
Default setting is "0" milliseconds.

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 anymore. The device can then "disconnect" the TCP connection or it can "skip" the stream directly to the encoder stream without disconnecting TCP.
Default setting is "disconnect"

Background Stream TCP Flow Control

The Background Stream TCP Flow Control defines data receiving strategy of stream interrupted by a priority stream (so called background stream). If a priority stream is played, data in original stream can be either accepted and thrown away or the TCP connection can be stopped.
Use throw away data if your streaming source is streaming in real time (e.g. Annuncicom). Use stop stream when the streaming source is sending data as fast as possible (e.g. when sending a file from a PC).
This setting is only for receiving data and does not affect UDP streams.

Streaming Strategy

The Streaming Strategy defines how a packet is built 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.
Default setting is "lowest latency".

Non MP3 Packet Size

The Non MP3 Packet Size defines with how many bytes a non MP3 packet will be filled up before it is sent. Set to a value between 1 and 1200.
Default setting is "1200"

Play Buffer

Defines the amount of bytes that will be stored before playing the received stream. Lower this value to minimize delay, increase this value to prevent dropouts.
Default setting is "4096" Bytes.

Receive Timeout

Defines the amount of time between the end of a received stream and switching to being able to send.
Default setting is "200" msec.

TCP Priority Rx Port

Enter the port number for receiving a priority TCP stream. This stream always takes precedence. Set to a value between 0 (disabled) and 65535.
Default port is "0".

UDP Priority Rx Port

Enter the port number for receiving a priority UDP stream. This stream always takes precedence. Set to a value between 0 (disabled) and 65535. Default port is "0".

Priority Message Minimum Volume

This is the guaranteed minimum volume for the priority message (received through UDP or TCP Priority Streaming Listen Port). If the current volume is less than this and priority message begins, the volume is set to this volume and reset back to original value when the message ends.
Default: "25%".

UDP Receiver Port

Enter the port number for receiving a UDP stream.
Set to a value between 0 (disabled) and 65535.
Default port for UDP is "3030"

UDP Tx Source Port

This setting is only used when working with a custom software application. Enter the source port number to be used when sending a UDP stream. Set to a value between 0 and 65535. When set to 0 the port defined in the Stream table destination entry is taken. Or if Stream destination is set to "origin source" then the UDP Receiver Port is used.
Default setting is "0".

Radio Path

Enter a radio path to listen to the transmitted stream of this Barix Annuncicom 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
The device can serve up to 6 radio streams.
Default setting is "/xstream".

Relay While Audio

Activate relay when sound is coming out of the analog output and deactivate when not.
Default setting is "OFF".

Stream

There are two ways streaming can be set up:
1) Automatically by responding to the last calling station (to the device from where the last communication came, viz. "to the origin source").
2) By means of Tables containing IP addressing information. Refer to section 3.5 Table Settings for information on configuring tables.

Choose if the stream should be sent to the defined entries in the table or "to the origin source"

Current Table

There are 8 tables available, each with 8 entries. Only one table is in use at any particular time.

This parameter shows the current table selected over the remote command interface or the home page.

Multicast Address

Enter a Multicast address on which to receive an audio stream. As receive port the "UDP Receiver Port" is taken. At start up the device will join the multicast group by periodically issuing IGMP join group messages.
Default setting is no address set, "0.0.0.0".

3.4.4 I/O Settings

These settings adjust the device behaviour for startup, inputs and outputs (attached buttons, the serial CTS signal and the relay pulse duration).

Command Broadcast

This option is for backward compatibility with firmware versions prior to 1.16. If you want "r=c=" commands to be broadcast (UDP broadcast), set to compatibility mode. Otherwise choose secure mode, then "r=c=" commands will be sent only if stream to origin source is set and the origin source is known (command will be sent to the last partner).

Note

This security option should be used very carefully and is intended for advanced users only. Since the CGI commands used in the web interface do not make use of passwords, setting this password would disable any control of the device using a browser.

Level 4 to 6 (User)

Enter up to 24 characters to secure the access to customized web pages in 3 levels. Intended for advanced users only, for details see the Technical Documentation. Without a valid password these user web pages cannot be viewed.
Enter 25 characters to erase the current password.
Default: "not set"

Listening

Choose which level is used for preventing unauthorized listeners from listening to Annuncicom as Internet Radio, or "not protected" for access for all.

SNMP Community RWrite

Choose a password for the Read and Write Community, or "not protected" to ignore both the read and write communities or "no write access"

SNMP Community Read

Choose a password for the Read Community, or "not protected" to ignore the read community or "no access"
Note that the Community RWrite setting takes priority.This means that if the Community RWrite is set to not protected, Community Read is ignored.

3.5 Table Settings

These settings adjust the table entries.

Table

Up to 8 entries can be set in a table. Each entry can be configured to stream to a device, a multi- or broadcast address or to be a listener (server).

The numbered links (Table 1, Table 2 etc.) allow additional tables to be configured which can then be selected via the home page or over the command interface. Only the configured Current Table (see section 3.4.3 Streaming settings) is active at a particular time.

Conn. type

Choose the type of connection:
"not used" for unused entries
"Internet Radio" for an internet radio station (1 user) (default)
"Raw UDP" for a UDP connection
"Raw TCP" for a TCP connection

IP ####

Enter 4 values of the entry IP address e.g.:
"0.0.0.0" for unused entries (except when the connection type is set to UDP it will be broadcasted e.g. "192.168.0.255")
"0.0.0.0" for connection TCP + Port if this device is used as a TCP listener waiting for a connection from a streaming device. (default)
"192.168.0.34" for a directed connection
"192.168.0.255" for a broadcast
Default settings:
Entry # 1 in table 1"Raw UDP 0.0.0.0:0". This means it is UDP broadcasting on port 3030!
All other entries are set to "not used" except for table 1 where all entries are set to "Internet Radio 0.0.0.0:0".

Port #

Enter the port number for each entry (between "0" and "65535"). If this port is set to "0" then the default ports are used (Internet Radio "80", TCP "2020", UDP "UDP Receiver Port" or if "0" then "3030").
Default setting is "0".

Notes

The choice of settings to distribute the stream to the other station(s) depends on your environment and desired functionality.

If the reception of up to 8 streams need to be guaranteed we recommend using TCP since lost packets are retransmitted automatically. I

f the stream is intended to be received by many devices we recommend using UDP broadcast (as long as all devices are on the LAN as broadcast is not passed over a WAN by the routers).

If your network infrastructure is capable of multicasting use multicast to reduce the traffic generated by broadcasting.

A mix of all the above is possible as each of the 8 destinations allow an individual choice of connection type.

4 Reverting to factory defaults

Click on the DEFAULTS button to enter the defaults page.

You will see the following screen:

Click on "Factory defaults" to revert all settings except "Network configuration" to factory defaults. While restarting the device the following screen appears showing a number counting down:

Upon start up the following screen appears stating the successful reverting to factory defaults:

Hard default settings

To revert all settings (including the network settings) to factory defaults the Reset button has to be pressed for about 5 seconds while the Annuncicom is powered.

Important note

Use this method if a connection to the Annuncicom cannot be established. This can happen if you have set a Static IP address once, switched off Sonic IP and then forgotten the IP address. The Hard default settings sets the IP Address to automatic discovery (0.0.0.0) and enables SonicIP.

If this fails we recommend downloading the Annuncicom Rescue Kit from www.barix.com. Unzip the Kit and read "readme1st.txt" for instructions. This Rescue Kit reloads the entire firmware, resets the device to factory default settings using the supplied serial cross cable and a PC running W2K or XP.

5 Rebooting the device

Click on the REBOOT button to enter the reboot page.

You will see the following screen:

Click "Reboot the device" to restart the Annuncicom.

Click on downloads and then click on Annuncicom. Scroll down to the section Firmware. Download the firmware update package and unpack to a local drive. If your device can not be reached over the network using a browser the Rescue Kit can be used. Read "readme1st.txt" for instructions. This Rescue Kit reloads the entire firmware, resets the device to factory default settings using the supplied serial cross cable and a PC running W2K or XP. If your device is reachable by browser follow the next steps to update the device over the network.

6.1 Step 1

Click on the UPDATE button to enter the update page.

You will see the following screen:

6.2 Step 2

In order to upload a new firmware click on "Please click here to start the update". After a count-down the device will restart in a special mode called Bootloader. Please note that in this mode the standard HTTP port 80 is always used.

Upon start up the following screen appears ready for the update process.

6.3 Step 3

To upload an update click on "Browse..." to locate the file you want to update.

The file is named compound.bin If you load the wrong file the device will not work and then the Rescue Kit must be used.

Click the "Upload" button and wait for a confirmation of the upload.

Do not interrupt the upload process, reset or power off the device until the firmware is loaded.

After the file completely loads, click on update and then press the "reboot" button to restart the device with the new firmware. The device takes a few seconds to reboot.

7 The "How To" section

7.1 How to set the Annuncicom for listening using WinAmp

Follow these steps to ensure correct settings in the Annuncicom.

7.1.1 Step 1

Open your Web Browser.

7.1.2 Step 2

Type in the IP address of the Annuncicom and hit enter.
Example: 192.168.0.12

7.1.3 Step 3

Click on the Configuration link.

7.1.4 Step 4

Click on the STREAMING tab in the SETTINGS menu.

7.1.5 Step 5

Choose "send always" in the Streaming mode field.

7.1.6 Step 6

Make sure that Radio Path says: /xstream and that at least one entry in the active table (usually table 1) is set to “Internet Radio 0.0.0.0 : 0"

7.1.7 Step 7

Open WinAmp

7.1.8 Step 8

Under the file menu choose Play Location (Play URL in version 5) or hit CTRL and L on your keyboard.

7.1.9 Step 9

Enter the IP address of your Annuncicom followed by /xstream.¨

Example: 192.168.0.12/xstream.

Hit the Open button.

7.1.10 Step 10

WinAmp will open the stream and buffer it. Wait a few seconds (to fill the buffer) before you can hear the input signal in WinAmp.

7.1.11 note

Once this works you can also try to set the Streaming mode to "send on TALK/CTS". Every time TALK is activated WinAmp will start playing.

Also test the impact of different Quality and Sampling frequency settings. Play with the Buffer settings in WinAmp to reduce dropouts or minimize delays.

7.2 How to listen using Windows Media Player

Follow the steps 1 to 6 in chapter 8.1 to ensure correct settings in the Annuncicom.

7.2.1 Step 1

Open your Windows Media Player and click on Open URL under the menu File.

Enter the IP address of your Annuncicom followed by /xstream.

Example: 192.168.0.5/xstream

Hit the OK button.

7.2.2 Step 2

The Media Player will open the stream and connect to the Annucicom. This is indicated by a single “)” going from left to right and back in the stream bar on the bottom right.

7.2.3 Step 3

The Media Player will connect and indicate this by the Play button appearing and a steady display of two “))” in the stream bar on the bottom right and as buffering proceeds the number of ”)” will increase.

7.2.4 Step 4

The Media Player is programmed for playing streams from a server and calculates the buffer automatically. Because the Annuncicom is streaming in real-time the buffer calculation assumes a slow connection and would buffer for about 2 minutes. This can be shortened by clicking on the Play button. The playback then starts immediately.

7.2.5 Step 5

If you think that the delay is too be big the Media Player can be tuned to shorten it. Change the setting in the Performance Tab (under the menu Tools/Options) as shown below and make sure that you click on Play as soon as the button appears.

8 Application notes

This section will show you how to set the Annuncicom devices in common applications.

8.1 Two station intercom

Situation: two stations with one TALK button each. Annuncicom’s default settings are already configured to allow two station intercom with only a few changes.

8.1.1 Station 1 configuration

Wiring

Station 1 is connected to an intercom panel:
Speaker to speaker out (C).
Microphone to Microphone In (E or F).
The TALK button to Input 0 (B1 and B3).

Network settings

If you have a DHCP Server in your network the device will automatically get an IP address and no changes are needed. Skip this step and go to Audio settings.

Use the following settings if you prefer to have a Static IP or if no DHCP server is available.

SonicIP is disabled; no need to hear it on power up as the IP Address is static and known and the device will stay powered most of the time.

Audio settings

Change the Input source to "Mic".

The Microphone Gain as well as the Volume might need adjustment later on depending on the microphone and speaker used.

Quality and Sampling frequency settings can be decreased to lower the network traffic but this will increase the playback delay.

Streaming settings

No changes needed.

Streaming mode is set to talk when the TALK command is activated (i.e. TALK button pressed). Post Trigger Play is set to talk on for 1 second after the button has been released. This prevents cut offs. When receiving a stream, 4096 Bytes will be buffered first before playing it back over the speaker. Lower this value to minimize delay, increase this value to prevent dropouts.
The stream will be transmitted using a UDP broadcast on port 3030.

IO settings

No changes needed.

The I0 pushed command c=83 will activate the TALK mode when the TALK button is pressed.
The I0 released command c=84 will deactivate the TALK mode when the TALK button is released

Security settings

These settings need not to be changed for now. Adjust them later according to your security needs.
Adjustments for Station 1 are completed.
