Features

The encoder/decoder Solidyne ADA102 is a stand alone streaming generator, designed to work as Studio to Transmitter Link (STL). Encoder works with stereo audio signals turning it into an MP3 or PCM audio streaming, under different modes (see specifications).

The coded output is an RJ45 connector compatible with

Ethernet TCP/IP networks. ADA102 has analogical audio inputs (balanced) and digital AES-3 or S/PDIF.

At the other end, an ADA102 set as DECODER convert the incoming stream (from Internet or microwave link

802.11.x) into analogue audio signal or a digital stereo

AES-3 (S/PDIF compatible), sent to transmitter.

Model ADA102mpx decoder incorporates a third type of output: Baseband MPX for direct connection to a broadcasting FM transmitter.

The unit has four relay remotely managed. At the encoder, four inputs manages four switches on the decoder, and vice versa.

The USB port lets you connect a pendrive when the

ADA102 works as a decoder. If the incoming streaming

SOLIDYNE

ADA102 CODER/DECODER drops by congestion or network failure, the ADA102

Decoder will start to play audio files from USB device until the connection restored.

The serial port support "gateway". From studios, using a computer connected to the ADA102 encoder, you can command a remote device directly connected to the

ADA102 decoder at the transmitter plant, as if the device was connected directly to the computer on Studio.

Main features

Power supply

Always CHECK the correct position of the

VOLTAGE SELECTOR (200/240V o 100/130V, according to the country)

AC wires do not have to be mixed with audio wires, especially with analogical ones. Remember that all audio installation must have a trustworthy grounding. We recommend accomplishing with the standards - Article

810 of the National Electricity Code (NEC); ANSI/NFPA Nº

70-1984 in USA; IRAM 2379 and 2281-3 in Argentina.

This standard provides information and guidelines for a consistent grounding.

1.2.2

Audio inputs and outputs

Analog inputs and outputs are electronically balanced.

The inputs are “bridging” type, with impedance greater than 10 KOhms. The connectors used, as is standard, are female XLR-3 for the inputs and male for the outputs.

SOLIDYNE

ADA102 CODER/DECODER

Take specially care with the phase.

 Use one pair shielded audio cables of good quality, preferably with double shielding. The maximum length recommended is 30 mts, although in special cases it's possible to achieve

100 mts. accepting a little loss at high frequencies.

 The connection of this cables are made as is standard. See the following table:

Balanced input/output connections:

1 = GND

2 = balanced positive phase (+)

3 = balanced negative phase (-)

Unbalanced connections:

Inputs: Signal = 2; GND = join 1 y 3

Outputs: Signal to pin 2; leave pin-3 unconnected. GND = pin 1

S/PDIF device can connect to AES-3 input/output of

ADA102 using an S/PDIF to AES-3 adapter.

No software setting is needed to enable AES-3. Decoded audio are always sent to Analog and AES-3 outputs.

1.2.3

LAN port

Standard Ethernet RJ45 10/100 to connect the unit to a switch/router to send or receive audio streaming.

1.2.4

USB port

Lets plug in a flash memory storage (Pen Drive) when the unit works as a decoder, so that in case of loss of streaming, the decoder switches to the Pen Drive to continue with the audio playback. USB 1.1 compatible devices are supported, with the following limitations:

•

Only mass storage devices are supported.

•

HUB's are not supported (some flash drives have an internal HUB)

•

4GB is the maximum capacity. If the flash disk is larger, create a 4

GB partition. Only the first partition is supported.

•

First partition mus be FAT16 format.

If your computer does not recognize the pen drive, the following procedure can help you find the reason:

•

Open an Internet browser, enter the ADA102 IP address followed by /status (i.e.: 102.168.0.110/status).

•

Scroll down until "USB device info"

•

Check if "Filesystem type” is "FAT16". If it's "FAT32", reformat the

USB memory as FAT16.

The USB must contain a playlist file named

"playlist.m3u" which determines the order in which

MP3 files are played. This playlist can be created with the Winamp audio player (www.winamp.com) or any software that generate .m3u playlist files.

When the USB is puged, ADA102 will reboot to detect the device, so audio output will be muted by few seconds.

1.2.5

Serial port

The serial port is used to command, from the studios, a device located in the transmitter plant as if it were directly connected to serial port of the computer at the

Studio. For this ADA102 generates a gateway for transporting serial data transparently through the network (see "2.3 - Advanced Settings). The connection requires a standard RS232 cables.

SOLIDYNE


1.2.6

Remote control

Each unit has four inputs and four outputs for remote control. Each input can controls a switch off the remote unit.

Inputs are type “dry inputs”. To enable an input (input

“on”) send it to a GND pin of DB-15.

The output switches 1 and 2 are "open collector" type

(used for example to command external control circuit).

Switches 3 and 4 are mechanical relays that can manage up to 1 A @ 24 VDC.

1.2.7

MPX output (optional ADA102mpx)

The model ADA102mpx includes a stereo coder that generates the FM baseband signal. This output is connected to an FM transmitter. The MPX cable is a

RG-59 (coaxial 75 ohms), like the used for CATV. The output connector is BNC. The maximum length recommended for this cable is 25 m. Take care with the grounding; although this rarely is cause of problems because all Solidyne processors have MPX differential outputs, that is to say, with the ground isolated from the cabinet, to avoid ground loops. If some residual humming appears when the system is on the air; power off ADA102. If the humming disappears, check the input connections at the decoder. If, however, the humming continues (and only disappears unplugging the MPX cable), this indicates some important problem with the grounding.

When enters to the transmitter through the MPX input, make sure that the internal pre-emphasis network IS

DISCONNECTED (that is to say, flat response from 20

Hz to 100 KHz). Contrary, when use an external stereo coder, make sure that the generator INCLUDES the pre-emphasis curve. This is due that ADA102 audio output DOES NOT INCLUDE pre-emphasis (only the

MPX output has pre-emphasis).

1.2.8

Reset

Pressing this button restarts the unit. Press and hold for

10 seconds to reload the factory defaults.

If you start your computer holding down the button for 5 seconds, ADA102 starts in “firmware update” mode.

1.4.1 Connection diagrams for streaming transport

The figures above shows two examples of streaming link in FM stations.

In diagram (a) the audio processor is located at the studies, and carries the processed audio to a

ADA102mpx connected directly to transmitter. In this way the processor works with the audio signal directly from the console, and ADA102 carries the processed audio.

This is the recommended configuration for FM.

The diagram (b) shows a chain of 100% digital audio, using inputs and outputs AES-3. In this case, the processor appears in transmission plant, which is processing the audio decoding of MPEG streaming. The output of MPX audio processor is connected directly to the transmitter.

In AM stations, the audio processor must be close to the transmitter to maintain a DC coupling that allows the asymmetric modulation.

Levels adjustment

1.4.2.1

Audio processor locates at the studios with analogical connections

When the audio processor is at the Studio, connected by analog input – case (a) mentioned above – the input level of ADA102 CODER is a critical issue.

•

Choose a high density musical program.

•

Play on-air the music and check the audio processor to verify that the AGC compression be 10 dB or higher.

•

Adjust carefully the ADA102 input gain to obtain a 0 VU deviation with the peaks.

Needle must never overpass the 0 VU indication.

At the other end, ADA102mpx receives the streaming.

The incoming streaming is decoded and sent to MPX stage. To adjust the 100 % of modulation proceed:

•

ADA102mpx has two presets at the rear panel:

MPX level and 19 kHz Pilot Tone level.

•

Playing the same high-density song used to adjust the CODER, adjust the MPX level preset to obtain 100% of modulation at the transmitter. Read this value at the exciter

VUmeter

•

If you have a modulation meter available

(Solidyne VA16, Belar, Innovonics, etc.) we recommends to use the measurements of this instrument instead of the exciter value.

SOLIDYNE


•

If you have a modulation meter available, adjust the pilot tone depth to 8% / 10% using the correspondent preset of ADA102mpx. If you don't have a modulation meter, do not change this preset.

Do not push the screwdriver. The preset can be broken.

The level knob at the ADA102mpx front panel do not changes the MPX level. Only take effect on the level of balanced outputs, so it must be adjusted only to obtain a visualization at the VU-meters, which will indicate that

input streaming is present.

The internal input gain (software) do not be changed.

It must be -1 dB (default value).

1.4.2.2 Full digital connections

Whenever the audio processor is located, in a full digital audio chain – case (b) mentioned above – the controls on frontal pannel do not take effect over the signal. The adjustment is made from web control pannel. The level of the digital audio is not changed by the encoding– decoding process.

•

You must set the output level of the decoder output (wich excites the stereo coder input) according to the output level (dBfs) of the audio processor. Default output level is -1 dB (for use with analog signals).

This level is adjusted from web control pannel, in the section Basic Settings → Configration →

Audio (Output Audio Level).

Next, a table with reference Output Audio Level values, A continuación una tabla con valores de referencia.



The knob level at the front panel only takes effect over analog inputs, and the VU meters do not operate with digital signal.

•

To adjust the modulation depth, proceed like the previous case (MPX preset).

1.4.2.3 Audio processor locates at transmission plant

When ADA102 links the Studios to Transmission Plant, where ADA102 DECODER connects to the audio processor; the audio level managed by ADA102 link is

not critical, since the processor at the end of chain controls the level sent to the transmitter.

•

In ADA102 CODER, adjust the input gain to reach 0 VU with signal peaks. If you are connecting the AES-3 input, the level adjustment is no needed (neither possible).

•

In ADA102 DECODER, adjust the output level knob to reach 0 VU with signal peaks. If you are connecting the AES-3 output, the level adjustment is no needed (neither possible).

•

Now follow the Audio Processor user's manual in order to adjust the modulation.

1.4.3 Using an RF digital link

The use of a ADA102 CODER in studios connected to broadband Internet, allows to cover any distance from studios to transmitter plant. This solution can be used to

STL links and for radio networks, so one coder from studios can send a signal to several slaves throughout the country.

Another solution to transport the audio streaming maintaining the great sound quality at low cost: a

microwave link for 5.8 GHz (or 2,4 GHz in some countries) using the standard 802.11.x. This band is

free in all countries and does not require any special authorization. It is able to cover 45 Km and should not have major obstacles between the two sides.

Software settings

2.1

ADA102 into the Studios – Brief guide

ADA102 can be settled to work as a coder, as decoder, or both at once for full-duplex connections.

In this example we assume a unidirectional link (halfduplex) between Studios and Transmitter Plant. In the

Studios the ADA102 works as ENCODER, generating and sending an audio streaming to the transmitter. At the transmitter plant ADA102 receives the streaming and decode it to audio.

Step 5

Since this unit will send streaming from the studios, is set as an encoder to generate the streaming. For make this, go to option “Configuration” and select “Basic settings” in the left drop-down menu.

•

Define “Stream method” as “Push (RTP)”

•

In the field URL enter the IP or DNS, and the destination port for the streaming. ADA102

CODER will stream directly to this IP address.

•

Press “Apply” to confirm these values.

2.1.1

Entering to ADA102

ADA102 is configured using a web browser. By default, ADA102 uses "Dynamic IP" so that when connected to a LAN, gets an IP address via DHCP

(the router assigns an IP). The procedure is as follows:

Step 1

Plug the unit to the LAN using a standard RJ45 cable.

Step 2

Plug a headphone to the frontal panel connector.

Please have your pen and paper to write the IP address that will be announced.



The level of the headphones is managed by the output gain knob. If you don't hear the IP, check this knob.

Step 3

Power on ADA102 (main switch locates at the rear panel). The ADA102 CODER will search for a DHCP server to get an IP address. Once obtained the IP, your ADA102 is now ready to start working. Green Led on front panel will blink.

If no DHCP server is found then ADA102 will search the network for a free IP address (this could take up to 5 minutes). If all is right,

DATA LED at the front panel will blink. If the front LED's (“data” and “error”) stay dark check the power cabling. If it still fails, please contact to Solidyne.

This destination IP address is the external address of

the network where the decoder is located (the static IP assigned by your ISP). When packets reaching the router/firewall at the other end, they should be redirected to the local IP address of ADA102 DECODER (eg.

192.168.0.30).

As the CODER transmit to a specific IP address and port, all packets arriving at these Port in these address must be forwarded to the DECODER, wich converts to audio.

Identify which packages must be address using the “port

forwarding”.

2.1.3

Audio options

Step 6

Step 4

Open an Internet browser (i.e. Firefox, Internet

Explorer) and enter the announced IP address. The web control panel will appears on screen.

ADA102 at the Transmitter Plant – Brief guide

2.2.1

Instalation

Step 1

Plug the power cord to AC outlet. Check the voltage switch at the rear panel.

Step 2

To configure the unit, you must access the web control panel. By default, ADA102 uses "Dynamic IP" so that when connected to a LAN, gets an IP address via DHCP

(the router assigns an IP). The procedure is as follows:

Step 3

Plug the unit to the LAN using a standard RJ45 cable.

Step 4

Plug a headphone. Please have your pen and paper to write the IP address that will be announced.



The level of the headphones is managed by the output gain knob. If you don't hear the IP, check this knob.

Step 5

Power on ADA102 (main switch at the rear panel). The

ADA102 CODER will search for a DHCP server to get an

IP address. Once obtained the IP, your ADA102 is now

ready to start working. Green Led on front panel will blink.

If no DHCP server is found then ADA102 will search the network for a free

IP address (this could take up to 5 minutes). If all is right, DATA LED at the front panel will blink. If the front LED's (“data” and “error”) stay dark check the power cabling. If it still fails, please contact to Solidyne.

Step 6

Open an Internet browser (i.e. Firefox, Internet Explorer) and enter the announced IP address. The web control panel will appears on screen.

2.2.2

ADA102 working as decoder

At the transmitter plant, the unit works as pasive receiver, receiving the streaming from ADA102 CODER, so it must be set as “Transmiter decoder” from the option “Location”.

SOLIDYNE


Step 7

When the device is set as “Decoder”, it loads the default values for receive streaming, and usually you don't need to change this values (with the exception of port numbers and IP addresses). Next, the most important settings are descripted.

Click on “Configuration → Streaming”

Keep-alive: Displays the current configured keep-alive strategy.

Step 8

In the field “Port” enter the same port number used in

ADA102 CODER. Hit “Apply” to confirm.

Step 9

At the decoder, you must to pay attention to the buffer

size, which is the memory that holds the incoming streaming audio to avoid drops. These interruptions occur when the bandwidth is insufficient for the transmitted audio quality and can be solved by increasing the buffer size.

But note that larger buffer size will cause greater delay time. The appropriate value depends on the bandwidth of the network and type of audio streaming.

Buffer size is expresed in miliseconds. For uncmpressed

PCM streaming times of 40/80 mS works find. For coded formats larger times are nedded due to the times involved in the decoding process (see “2.3.5 - About audio options”).

No other value must be defined. ADA102 automatically recognize the incoming streaming. The audio quality is defined in the CODER.



Emergency Pen Drive: Remember that you can connect an

USB device (Pen Drive) in the USB port. In case that the streaming lost by network failure; ADA102 will play audio from

USB device until the connection restores.

2.2.3

Status screen

Site type: Shows the working mode of the unit. In this case the device woks as DECODER, located at the Transmitter

Plant. It works as pasive receiver decoding the incoming streaming from Studios (“Transmitter decoder” ).

Stream mode: Displays the current configured event to start streaming to the remote destination(s).

Advanced settings

2.3.1 Setting temporary IP address using ARP command

This procedure is used to temporarily set the IP address for first time browser access to the ADA102, in the case where you have no LAN and wants to access from a

Notebook.

After this procedure the temporary IP will be active only as long as the ADA102 stays powered. After a restart the procedure has to be repeated unless you have configure it with a static IP address.

Step 1

Use either a “crossover” network cable between the

ADA102 and the PC or use two network cables to connect the ADA102 and the PC to a network switch and power the ADA102.

Make sure that you have a valid IP address configured on your PC (e.g. 192.168.0.2).

Step 2

Open a command window. Windows: click on “Start”, click on “Run..”, in the “Open” field type cmd , click on “OK”.

OSX / Linux: Open a terminal window

Step 3

Please proceed to step 4 if you used a “crossover” network cable in the preparation step above.

To ensure that we use a free IP address (not already used by another device in the network) we have to use the Ping command. In this example we assume the PC to have the

IP address “192.168.0.2” and want to check if

“192.168.0.6” is free.

To do so type ping 192.168.0.6 and hit the “Enter” key.

If you get a reply (IP already used) then try to ping another

IP until you find one that is not used. If the request times out (no reply) then the “pinged” IP is free and we can continue with the next step.

Step 4

Look for the Solidyne ADA102 MAC address printed on a label placed on the rear panel (12 hex digits, separated by a hyphen every 2 digits). Type into the windows command window:

arp -s 192.168.0.6 00-08-E1-00-B1-77

and hit the “Enter” key (replace the digits according to your devices MAC address). On a OSX or Linux system type into the terminal:

arp -s 192.168.0.6 00:08:E1:00:B1:77

Step 5

Now we have to make the ADA102 listen to the IP address “192.168.0.6” using the Telnet command.

To do so type into the command window:

telnet 192.168.0.6 1 and hit the “Enter” key

(the number “one” must be there for this command to work correctly !!!).

The ADA102 will refuse the connection on port 1 immediately but will be available for web access on the

IP address used as long as the device stays powered.

Step 6

To check if the ADA102 is responding you can use the ping command again. To do so type:

ping 192.168.0.6

and hit the “Enter” key.

If you do get a reply the IP address 192.168.0.6 can be used to access the ADA102 using a web browser. If you do get “request timed out” then please repeat step 6 carefully (you most likely mistyped the telnet command) or repeat the entire procedure.

2.3.2 Static IP

You can define a static IP. The advantage is that a known

IP allows you to access to the web panel, in case that you requires change settings; without the necessity of listen the audio to know the IP (voice IP announced on start up).

By default the IP address is set to 0.0.0.0 (Dynamic IP disabled). To change it, go to “Configuration → Network”.

Use SonicIP:

If set to "yes", the device will announce its

IP address over the audio output. Default: "yes".

IP Address: Enter the IP address of the device, 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 used IP

Address. "255.255.255.0" for a C class network

Default: "255.255.255.0".

Gateway IP Address:

Enter the IP address of the

Gateway e.g.: "0.0.0.0" for no Gateway

"192.168.0.1" for a Gateway in a LAN.



The Gateway has to be set only when connecting to other devices over the WAN (through a router). Default: "0.0.0.0"

SOLIDYNE


Primary DNS: Enter the primary DNS IP address so the device con connect to URLs (e.g. www.radio.com).

Example: "195.186.0.1" Default: "0.0.0.0".

Alternative DNS:

Enter the alternative DNS IP address in case the primary DNS is not reachable.

Example: "195.186.4.111" Default: "0.0.0.0"

Syslog Address:

Destination address for syslog messages sent by the BCL program via the SYSLOG command. Set this to your syslog logging machine, if your syslog messages are recorded centrally.

If set to 0.0.0.0, syslog messages are broadcast.

Default: "0.0.0.0"

DHCP Host Name: Name of the device sent in DHCP request. If left empty, a name based on the device's

MAC address is generated automatically. Enter up to 15

Characters.

Web server port: Defines the port where the webserver of the Solidyne device can be reached. If set to "0" the default HTTP port (80) is used.

while incoming audio buffer is empty.

"always OFF": Relay will be OFF always. Default setting is "always OFF".

2.3.3

Remote control

ADA102 has four electronic switches managed by the remote Solidyne device. Four inputs at the CODER manages four switches in the DECODER, and vice versa. In addition, switches can be controlled by other events.

In the control WEB panel, go to option “Configuration” of main menu. Section “I/O and Control” allows to define the behavior of electronic switches. Available options are:

"ON while remote Input X ON": Relay will be ON while the button with proper Input number is pressed on remote device.

"ON while connection ON": Relay will be ON while connection is defined by keep-alive.

"ON while connection OFF": Relay will be ON while disconnection is defined by keep-alive (Alarm: partner missing!).

"ON while IN audio ON": Relay will be ON while audio input is above "Input Trigger Level" (with "Inactivity

Timeout" delay).

"ON while IN audio OFF": Relay will be ON while audio input is below "Input Trigger Level" (with "Inactivity

Timeout" delay)

"PULSE ON with IN audio change": Relay will be pulse

ON if audio input changes its state via "Input Trigger

Level" (with "Inactivity Timeout" delay).

"ON while incoming stream ON" Relay will be ON while incoming audio buffer is full.

"ON while incoming stream OFF": Relay will be ON

SOLIDYNE


By default, relay Nº1 is ON while the connection is alive. Relays 2, 3 and 4 remain OFF.

SNMP Destinations IP(s)

For alarm sending, set the desired list (colon separated) of SNMP trap receivers.

SMTP Server IP/DNS

For alarm sending, set the IP address or DNS name of the SMTP server.

Local e-mail (FROM:)

FROM mail address, for SMTP alarm service.

Destination e-mail(s) (TO:)

TO mail address, for SMTP alarm service. Multiple email addresses have to be separated by colon.

2.3.4

Serial port

The ADA102 serial port allows control from a PC in the Studios a remote device located in the transmiter plant as if it were connected directly to the serial port of the computer at the Studios.

•

A the Studios, the computer connects to ADA102's serial port, using null-modem cable (crossed

RS232).

•

At the Transmitter Plant, a device (i.e. a broadcast

RDS coder) connects to the ADA102-s serial port, using a standard RS232 cable.

You must set the port to RS232 “tunneling”. In the

WEB control panel, hint the option “Configuration”. In section “Serial” the field “UDP/TCP Port for COM1” allows to enter a port number to serial communication.

You must use the same port in both CODER and

DECODER devices.

Page 18

The option “Serial 2” is not implemented. Leave

“UDP/TCP Control Port for COM2” as zero.

2.3.5

About audio settings

Encoding & Frequency

The unit supports the following audio formats:

•

MPEG1 / MPEG2 (solo half-duplex)

•

uLaw/aLaw

•

PCM MSB/LSB first

The passive receiver of a half-duplex system automatically recognizes the audio format but only for audio formats with fixed content.



AES3 / S-PDIF input uses MPEG1 and the sample rate detects automatically (32, 44.1 o 48 KHz).

2.3.6

Calculating the bit rate

The final bit rate is the sum of the audio bit rate and encapsulation of audio packets make the network protocol used. For RTP the calculation is:

The Ethernet total overhead per packet is 300 bit.

The IP total overhead per packet is 160 bit.

The UDP total overhead per packet is 64 bit.

The RTP total overhead per packet is 128 bit (considering the enclousure MP3

MPA into the usable RTP overhead, that have a extra header of 32 bit).

Total overhead of bits per packet =

Ethernet Overhead + IP Overhead + UDP Overhead + RTP Overhead = 652 bit

Overhead/s = Overhead/Packet x Packet/s

Total Bit Rate (Kbit/s) = Audio Data Rate (Kbit/s) + Overhead/sec (Kbit/s)

(1Kbit = 1000 bits)

Remember: The playback buffer size is a very important question. This value expresses the buffer size in miliseconds. Smaller values minimize the delay, but increase the chance of audio drops. The optimal value depends on audio format and sample rate.

The audio bit rate expressed in bits/s, but the overhead is expressed in bits/packet. So we have to translate the overhead (bit/packet) in overhead rate (bits/sec). For this we need to know the number of packets per second, depending on the audio format. It can be measured with a software network protocol analyzer such as the "Wireshark".

Emergency pendrive

ADA102 only recognizes files with extension “.mp3”.

USB drive must contain the audio files placed directly in the root folder, and a playlist file named playlist.m3u, which determines the order in which files are played.

The playlist can be created manually using a simple text editor (eg Windows Notepad) and then changing the file extension from .txt to .m3u. Here's an example:

# sample playlist begin audio1.mp3

audio2.mp3

audio3.mp3

audio4.mp3

# sample playlist end

As files are in the root folder, it is not necessary to indicate the path. Lines preceded by pound (#) are comments.

The playlist can also be created using the audio player

Winamp (www.winamp.com) or any other audio player to generate playlists in .m3u. Usually create an .m3u

only requires to save the list of songs loaded on the player, as a playlist file type .m3u.

2.4

Other connection modes

2.4.1 Half-duplex link with unknown IP at the transmitter plant

In this case requires a half-duplex link between Studios and Transmitter Plant. Studios have static IP but the

Transmitter IP is unknown. The decoder (Transmitter

Plant) will start the connection to the studios.

2.4.2 Full-duplex link with unknown IP at the Studios

ADA102 at the Studios:

In the coder, go to “Configuration → Basic settings” and set the streaming method as “Pull (BRTP)”, the URL as

“0.0.0.0” and enter the listening Port for BRTP. Hit “Apply” to confirm the values.

This case is a full-duplex Studio to Transmitter link, but only the Transmitter Plant IP is known. The coder at the

Studios starts the communication to that IP address.

ADA102 at the Studios:

In option “Location” set the device as “Studio

Encoder/Decoder”. Go to “Configuration → Basic

settings” and enter the IP address or URL for send and receive.

Set the outgoing stream method as “Push(RTP)”. In URL

enter the IP of decoder (the external IP address that router redirects to ADA102 decoder at the Transmitter

Plant). The Port number is the the “Local Port” value assigned to the decoder in the Transmitter Plant.

Set the incoming stream as “Pull(BRTP)” since the IP address of coder is unknown. In the field URL enter the

IP of the transmiter plant (decoder) and the same port number assigned to de decoder.

ADA102 at the Transmitter Plant

At the Transmitter Plant, go to “Configuration → Basic

settings” and set “Stream Method” as “Pull(BRTP)”. In field URL enter th eIP address or URL of the CODER in

Studios. “Destination Port” must be the same assigned in the CODER. Hit “Apply” to confirm the values.

In a full-duplex link, both units must work with the same audio format. MPEG are NOT SUPPORTED for full-

duplex mode.

SOLIDYNE



At the Transmitter Plant ADA102 receives the streaming from Studios.

Set “Outgoing stream” as “Pull(BRTP)” since is the coder from studios who starts the connection. IP address is zero and the Port number mus be the used in the section “Incoming stream” in Studios.

Set “Incoming stream” as “Push(RTP)” with IP address zero, since the coder starts the connection to the decoder.

To implement this scheme, see your network administrator, because you need to configure the multicast routers.

ADA102 at the Studios

In this case ADA102 coder transmit to a multicast IP address.

Coder works in mode “Multicast”

(Configuration → Stream Method).


The decoder aslo works as “Multicast”. In the field URL you must define the same multicast IP used in the coder.

2.4.3 Link with repeaters

In this mode the coder send streaming to several devices simultaneously. This configuration is common when you have a static IP to the “multicast” group and requires a half-duplex link. In both Studio ans in Plant, ADA102 is set as “Multicast” (Configuration → Basic settings → Stream

Method).

Multicast is a protocol designed for maximum efficiency of the networks when required simultaneous transmission from one point to multiple destinations. Both the transmitter and receiver use the same IP address, which should be in a special range of IP addresses for a multicast. This range includes addresses from 224.0.0.0 to 239.255.255.255.
