INSTALLATION
Connecting your PYKO-out device
It is recommended to establish all connections before powering the device up.
Power supply
Before plugging the power cord, make sure it is not damaged.
Just like for any other audio system, power the individual devices up following the audio path and power
down in the opposite direction.
Do not allow anything to rest on the power cable. Keep the power cable away from where people could trip
over it.
Set-up
•Use an Ethernet cable to connect your PYKO-out to the network through its RJ45 port (labeled ‘ETH.’
on the back panel). To connect your PYKO-out directly to your computer, use a crossover cable.
•Plug your headphones (front panel)
•Prepare pen and paper in order to write the IP address down, which will be announced over the headphones
output.
•Connect the electric cable to the plug labeled ‘PWR’ on the back panel and to the power outlet
Audio
The pinout used on the XLRs is standard: pin 1 carries the signal ground, pin 2 carries the positive signal
(“hot”, +) and pin 3 carries the negative signal (“cold”, -).
Internal USB port
PYKO-out has an internal USB port for storing audio files (.mp3) in order to play them on the output. To use
this functionality, please insert a USB stick before powering the device up and connecting it to the network.
Note: These operations require opening of the cabinet and shall be done by qualified personnel only. The use of the
internal USB port disables the USB port on the front panel.
Configuration
You can use PYKO-out along with Audio Manager, in stand-alone or in EtherSound mode.
Firmware update
Digigram provides a firmware (compound.bin) compatible PYKO-out that is installed by default (factory
configuration).
Digigram may decide to publish updates of the embedded firmware. It may then become necessary to upgrade
your devices. In this case, please connect to the corresponding page on www.digigram.com/drivers/index.php
and download the most recent version. Then, go to the <Tools>, <Update> section of the PYKO-out html
page, click ‘Browse’ to indicate the location of the downloaded file, then the ‘Upload’ button. When the
message ‘compound.bin successfully loaded’ is displayed, click onto the link ‘Click on update before updating the
next component or unplug the power supply to reboot the device’ in the message, then onto the ‘Reboot’ button to
finish the update, or, alternatively, disconnect then replug the power cord.

MANAGING THE PYKO-OUT
Depending on your needs, there are several ways of configuring and controlling PYKO-out.
Configuration
PYKO-out embeds a web server that enables you to control the PYKO through your favorite Internet browser.
•Put your headphones on. At start-up, PYKO will announce its IP address over the headphones output
– write this address down!
Note: PYKO-out factory setting is IP address configured at 192.168.0.100
•Open your web browser.
•Type the PYKO-out IP address into the address bar and hit the ‘Enter’ key.
•You can now visualize the Web pages that enable you to parameterize the device. We recommend to
assign a fix IP address (Menu: Settings/Network)

Using PYKO-out with Audio Manager
If you use your PYKOs with Audio Manager, you will first have to either assign an IP address through the web
pages or turn the DHCP on (Audio Manager will then automatically assign an IP address). Audio Manager
Server will detect this address and allow the Audio Manager Client to configure it.
To be detected by Audio Manager, the TCP control port has to be set to “40002”, the UDP listening port to
“40004”. These are also the values defined in the factory configuration.
You may decide that Audio Manager is to control PYKO-out only in part. In this case, use the PYKO-out html
pages to configure the device accordingly (cf. on-line help of the pages).
For more details on managing PYKO through Audio Manager, please refer to its on line help.
PYKO-out in ‘stand-alone’ mode
You can now access the embedded html pages that will allow you to configure the device.

Next, set the parameters for the three audio stream priority levels (Menu: Audio)
For more details on parameterizing your PYKO-out in ‘stand-alone’ mode, please refer to on-line help of the
html pages.
Using PYKO-out with EtherSound
PYKO-out is also capable of decoding EtherSound 100/spkr (www.ethersound.com). This is an exclusive
mode of PYKO-out. In this mode, PYKO-out can decode two EtherSound mono streams.
As default setting ex factory, the equipment works in IP mode. Switching from IP mode to EtherSound is done
through the Web pages by selecting the EtherSound mode.
In EtherSound mode, the control of PYKO-out is done through EScontrol. Access to the web pages is no
longer possible.
To switch back to IP mode, PYKO-out needs to be reset (press the ‘Reset’ button for at least five seconds).
PYKO-out will re-boot with the default factory settings.
Note: each time PYKO-out is switched from one mode to another, the previous settings are lost, the device reboots in
factory configuration.

Priority levels
With the ‘Play-out’ firmware (default factory setting) there are three priority levels on the PYKO-out stereo
output. These three levels are accessible through the web pages.
•A stream sent on level ‘1’ will be played with the highest priority. Therefore, it is recommended to
assign the audio streams to the level ‘2’to let level ‘1’ available for a stream coming from an alarm
system.
•In case the level ‘2’ stream disappears, PYKO-out will play a level ‘3’ stream. As soon as the level ‘2’
stream(s) is (are) available again, PYKO-out switches back to this level.
Note: Certain functionalities such as for example the ‘Mute’ are not available at level ‘1’'.
These priority levels do not exist in EtherSound mode.
Particular mode of level 2
•If you use PYKO-out with Audio Manager, the stream coming from Audio Manager will be
automatically assigned to level ‘2’.
•It is possible from Audio Manager (or any other software featuring this functionality) to send several
streams to level ‘2’ of PYKO-out, provided that the port numbers are different.
That makes it possible to change the stream being listened to by switching either by GPI or by the
web page to the following stream.
Example: Audio Manager sends towards PYKO-out (i.e. towards same IP address) 32 different playlists (thus
on 32 consecutive ports). By either html page or GPI it is possible to pass to the following (port n+2)
or to the preceding stream (port n-2)
GPIO
PYKO-out is delivered with four GPIs and four GPOs on terminal block connectors; the counterparts are
provided. For details see Appendix D.
GPI
The PYKO-out GPIs are compatible TTL 5 V.
A GPI must maintain its state for at least 20 ms.
The GPIs can have either local action or a distant action by TCP tunneling.
For the local actions, the user can:
•choose whether it will take place on rising or falling edge
•modify the output volume + or –
•mute the output
•listen to the following or preceding level ‘2’ RTP stream
For the TCP tunneling:
•the changes of a GPI state are transmitted through TCP if an application is connected. This
information is received either by Audio Manager or by another application, but it cannot be received
directly by another PYKO-out.
•TCP connection is required by Audio Manager (PYKO-out is used as server). To establish the
connection, the listening port has to be configured by html page.
•the overall latency of the GPI signal transfer via Audio Manager to the destination GPO is inferior to
100 ms.

GPO
The PYKO-out GPOs are relay outputs.
It is possible to configure through the web page whether the initial value of each GPO is set to’0’ or to ‘1’.
The GPO can be configured by TCP protocol or from an application.
Serial port (RS232 on DB9)
PYKO-out provides a RS232 serial port on male DB9 on the back panel.
The RS232 can be used to control the PYKO through an external interface, such as e. g. Vity, AMX or
Crestron.
It is possible to use the RS232 in gateway mode, in multicast and multi-destination (up to 4 destinations)
Parameter setting of the tunneling is done from the PYKO-out html pages.
For the pinout of the serial port, please refer to the appendix F.
Audio format
PYKO-out can decode various audio formats, depending on the embedded firmware (see appendix A).
Decoding can be either mono or stereo.
Note: If for some reason the decoding parameter should not correspond to the one of the audio stream
received, PYKO-out will interpret that as an error and will not play the stream. PYKO-out will then
switch to the audio stream of minor priority (Stream priority level n-1).

APPENDIX B: USING THE INTERNAL USB PORT
These settings shall be executed by qualified personnel only!
Tools required:
•a #1 Pozidriv screwdriver
•an ESD-preventive wrist strap
Electrostatic discharge (ESD) can damage several components on the board. To avoid such damage in
handling the board, take the following precautions:
Bring the device and everything that contacts it to ground potential by providing a conductive surface and
discharge paths. As a minimum, observe these precautions:
•Disconnect all power and signal sources.
•Place the device on a grounded conductive work surface.
•Ground yourself via a grounding wrist strap or by holding a grounded object.
•Ground any tools that will contact the device.
•Unscrew the two flat-head Pozidriv screws
counterclockwise and open the cabinet.
•Insert the USB stick into the port provided for this purpose.

APPENDIX D: RTP FORMAT
An audio stream encoder must respect the size and the payload type described underneath.
RTP frame size
The maximum payload size in bytes for the encoder can be calculated from the formula:
Min(1300, 20.chans.Bps.samplerate/1000)
where chans is the number of channels, Bps is the number of bytes per sample and samplerate is the sampling
rate in Hertz;
The maximum payload size for MP3 is 1400 bytes.
RTP payload types
The following table shows the defined RTP payload types that the encoder must respect.
