PYKO-in: Professional IP audio endpoint
5.2. Operating modes
PYKO-in can be used in the following modes:
● standalone IP audio encoder: it is then configured from its WEB pages, and runs
autonomously,
● IP audio device controlled from the Digigram Audio Manager middleware (typical application
is background music and announcements management),
● EtherSound mono end-point.
● WEB radio encoder (Icecast/Shoutcast encoder)
PYKO-in is delivered with a firmware which allows the following operating modes:
●“Stream server”: when the ‘Stream Server’ application enabled, PYKO-in encodes the
audio signal it receives on its analog input(s), and stream this encoded signal as one or
several IP audio streams (mono or stereo).
●“Full-duplex”: The ‘Full-duplex’ firmware application allows using PYKO-in as full-duplex IP
audio codec working with one mono input and one mono output. This is useful for intercom
applications.
●“Play-out”: The Play-out firmware application lets PYKO-in decode a mono stream.
●EtherSound end-point: In the EtherSound mode, PYKO-in can decode one EtherSound
channel (mono). The control of PYKO-in is done through the EScontrol software application (
Access to the web pages is no longer possible).To return to another mode of operation,
please press the ‘Reset’ button > 5 sec in order to re-start PYKO-in factory configuration.
Now you have again access to the embedded html pages were you can select the required
firmware application and configure your PYKO-in.
“Stream server” and “Full-duplex” are the most commonly used applications. Stream server is the
default mode.
The Icecast/Shoutcast encoder mode requires that a specific firmware is uploaded (PYKO-in
Shoutcast).
See Appendix A for the features allowed by each firmware/application.
5.3. Firmware update
The firmware set in factory allows using PYKO-in in the following modes: Stream server, full-duplex,
play-out, EtherSound.
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 “PYKO-in support page” on the
Digigram WEB site, and download the most recent version. Then, go to the <Tools>,<Update>
section of the PYKO-in 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 re-plug the power cord.
10

PYKO-in: Professional IP audio endpoint
In case you need to use PYKO-in an Icecast/Shoutcast encoder, the firmware to be used is
“PYKO-in Firmware shoutcast”. The procedure to apply this firmware is as follows:
● Disconnect PYKO power supply cable.
● Connect the PYKO-in RS232 port to the computer COM port with a standard “null modem”
cable; hardware handshake is not required.
● From Command line, in update_rescue directory, type serial.bat COM1
● Adjust COM number according to your configuration.
● Reconnect PYKO power supply cable. Wait until upgrade is completed.
● PYKO is now in Shoutcast mode. Default IP address is 192.168.0.100.
6. MANAGING PYKO-IN
Depending on your needs, there are several ways of configuring and controlling PYKO-in.
11

PYKO-in: Professional IP audio endpoint
7. CONFIGURATION
7.1. Connecting to PYKO-in WEB pages
PYKO-in embeds a web server that enables you to control it through your favorite Internet browser
and to select the firmware application that best meets your needs.
● Put your headphones on. At start-up, PYKO will announce its IP address over the
headphones output – write this address down!
Note:  PYKO-in factory setting is IP address configured at 192.168.0.100.
● Open your web browser.
● Type the PYKO-in IP address into the address bar and hit the ‘Enter’ key.
7.2. Using PYKO-in 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.
Nonetheless, you may decide that Audio Manager is to control PYKO-in only in part. In this case,
use the PYKO-in 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.
7.3. PYKO-in in ‘standalone’ mode
● Select the application firmware that best meets your requirements (see above).
● You can now visualize the Web pages that enable you to parameterize the device.
12

PYKO-in: Professional IP audio endpoint
7.3.1. Audio configuration
‘Stream Server’ application case
It is possible to transport an IP stream from a PYKO-in towards different destinations:
● 6 in MP3 format
● 4 in PCM format
Just configure a destination IP address and a corresponding port for each destination.
13

PYKO-in: Professional IP audio endpoint
“Full-duplex” application case
In full-duplex mode, you will have to configure a mono input and a mono output.
To do so, go to the audio page ‘Audio: Stream priority 2’:
Configure the IP stream to be received (Listening stream) and the IP stream to be sent
(Server stream).
PYKO-in is now configured for a full-duplex communication.
In Audio Manager mode, the Audio Manager stream will automatically be set to level 2.
It is also possible to define a priority stream via the page ‘Audio: Stream priority 1’.
A full-duplex communication can then be interrupted by this priority stream for, e.g., an
alarm message.
14

PYKO-in: Professional IP audio endpoint
For more details on parameterizing your PYKO-in in ‘standalone’ mode, please refer to
on-line help of the html configuration pages.
With the ‘Play-out' firmware
For the use of PYKO-in ‘Play-out’ mode, please refer to the PYKO-out manual and to the
on-line help of the application firmware. Note, however, that with this firmware, the
outputs of a PYKO-in are managed in mono mode.
7.3.2. Remote control of PYKO through TCP commands
Remote control of PYKO through TCP commands
Menu Settings: Remote Control
PYKO can be controlled through ASCII TCP commands. The TCP port used for receiving the
TCP commands must be configured in « Device Control», « Port for TCP control
connection ». This port is the destination port used by a control application to send the TCP
commands to PYKO.
The ASCII commands are described in a separate document.
Local control of PYKO through commands sent via the serial port
15

PYKO-in: Professional IP audio endpoint
PYKO can be controlled through ASCII commands sent through its RS232 port.
The RS232 port parameters can be configured from Settings:Serial Link.
To enable this local control mode, go to “Settings:Remote Contro”, and from section « Serial
Link » select « Control » for parameter « Serial link mode ».
The ASCII commands are described in a separate document.
7.3.3. Tunneling of auxiliary data
7.3.3.1. RS232 tunneling mode configuration
RS232 tunneling consists in transmitting serial data from of a PYKO towards one or several
distant PYKOs (maximum 4). The transmission can be done in TCP mode (one PYKO to
another one), or in UDP mode (one to maximum four).
Note: the UDP mode does not guarantee that the distant PYKO receives the data.
The RS232 port parameters can be configured from Settings:Serial Link.
To enable the TCP mode, select « Gateway TCP server » or « Gateway TCP client » for
parameter «Serial link mode ».
- Gateway TCP server: in this mode, PYKO-out receives the serial data sent from another
PYKO on the port defined in « Connection port ».
16

PYKO-in: Professional IP audio endpoint
- Gateway TCP client : in this mode, PYKO establishes the TCP link with another PYKO
configured in server mode, and sends the serial data to the unicast or multicast address
defined in « IP address » and to the TCP port defined in « Connection port ».
To enable the UDP mode, select « Gateway UDP » for parameter «Serial link mode ». PYKO
listens to the serial data it receives on the UDP port defined in « Connection port ». The
parameter « IP address » must then be filled in case serial data are sent to a multicast
address.
PYKO can send serial data in UDP mode towards maximum 4 destinations. These
destinations are couples of « IP address / UDP port » defined in parameters « Destination 1 »
to « Destination 4 » in section « UDP transmission configuration ».
7.3.3.2. GPIO tunneling mode configuration
GPIO tunneling consists in transmitting GPI statuses of a PYKO to the GPOs of another
PYKO.
Its configuration can be done from section « GPIO tunneling ».
17

PYKO-in: Professional IP audio endpoint
PYKO can receive distant GPI statuses, or transmit its GPI statuses.
To receive distant GPIs statuses, select option « Server » from parameter « Tunneling
mode », and select the listening TCP port from parameter « Port for TCP connection ».
It is necessary to select the GPO which are concerned by the tunneling. From the page
Settings:GPO, select “On” for TCP tunneling, for each GPO that has to reflect the status of a
distant GPI.
If you need to invert the tunneled status on the GPO, select “Invert” Mode for each GPO.
To send GPI statuses, select option « Client » from parameter « Tunneling mode », and
select the destination IP address and TCP port from parameters « TCP server IP Address if
client mode » and « Port for TCP connection ».
Click on Apply to confirm the parameters.
7.4. Using PYKO-in with EtherSound
PYKO-in is also capable of decoding EtherSound 100/spkr (www.ethersound.com). This is an
exclusive mode of PYKO-in. In this mode, PYKO-in can decode ONE  EtherSound mono stream.
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-in is done through EScontrol. Access to the web pages is
no longer possible.
To switch back to IP mode, PYKO-in needs to be reset (press the ‘Reset’ button for at least five
seconds). PYKO-in will re-boot with the default factory settings.
Note: each time PYKO-in is switched from one mode to another, the previous settings are lost, the
device reboots in factory configuration.
