Power supply 24 VDC with plug to screw. 7

4. 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 a pen and a paper in order to write the IP address that will be announced on the ne (default value set in factory = 192.168.0.100). ● Connect the power supply cable to the plug labeled ‘PWR’ on the back panel. 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 features a USB port for connecting a memory stick for storing audio files (.mp3) and playlists for audio backup fo for announcements. The USB memory stick can be connected either internally (it is then necessary to open the box) or externally on the front panel. The USB stick has to be connected before powering the device up and connecting it to the network. If the stick is inserted once PYKO has started, This makes PYKO restart. 8

5. MANAGING PYKO-OUT Depending on your needs, there are several ways of configuring and controlling PYKO-out. 9

6. CONFIGURATION 6.1. Connecting to PYKO-out WEB pages 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 configure the device and get its status. The WEB page hereafter is displayed, and gives the firmware version (Application loaded), the IP address and Mac address. 6.2. Network parameters Go to « ​Settings​ » menu and select « ​Network​ » to configure the network parameters. These parameters are: ● Logical name: logical name of this PYKO on the network. ● IP address of PYKO-out In case PYKO is to be used in DHCP mode, enter 0.0.0.0. ● Netmask: subnet mask ● IP gateway: IP@ of the gateway if it is used ● Primary DNS: IP@of the Domain Name System server. Useful if the domain names are used instead of IP@. Domain name is often used when configuring Icecast/Shoutcast streams. 10

● DHCP hostname: name of the ● Ethernet link: allows to set the speed and mode of the network interface ( auto-negotiation, half/full duplex, 10/100 Mbits/s), ● IP address of an SNMP supervisor receiving the SNMP traps ● Web server port: http port (80 by default) ● password to connect to PYKO WEB pages (no password by default).Once the password is activated, this password must be entered to be able to connect to the WEB pages (no username is required). Several simultaneous connexions are possible. 6.3. Global parameters Go to menu « ​Settings​ », « ​Global Mode​ » The parameters are the following : - IP address announcement : enable/disable announcement of the IP address on the headphones output when PYKO starts. - Syslog Mode: enable/disable syslog messages. - Syslog Address: address of the Syslog client that received the Syslog messages (note that the UDP port used for Syslog is 514). 11

Click on “Apply” to take the settings into account, or “Cancel” to discard them. 6.4. GPIs configuration Go to menu « ​Settings​ », « ​GPI​», to assign an action to a GPI. It is possible to assign an action on rising edge or falling edge. Possible actions are: - increase/decrease output volume - Mute of the output - next stream decoding (in case several streams are declared on priority 2) Click on “Apply” to take the settings into account, or “Cancel” to discard them. 6.5. GPOs configuration It is possible to define the status of each GPO (0 or 1) at PYKO start up, and to define which GPOs are involved in the tunneling mode. To access the parameters, Go to the menu " Settings ", "GPO", and select the appropriate parameters. 12

Click on “Apply” to take the settings into account, or “Cancel” to discard them. 6.6. Serial port configuration Parameters of the serial port can be configured from the « ​Settings​ » menu, « ​Serial​». PYKO serial port can be used either to transmit RS232 data to the serial port of distant PYKOs, or to locally send real time commands to a PYKO. If the serial port is used, it is necessary to configure its parameters : - ​Baud rate ​: bit rate (from 300 to 230 400 bits/s) - ​Data bits ​: number of bits for data (8 or 7 bits) - ​Parity​ : parity bit (no bit, ‘even’ parity bit, or ‘odd’ parity bit). - ​Stop bits​ : number of stop bits (1 or 2) - ​Handshake​ : serial transmission mode (no protocol, XON/XOFF protocol , RTS/CTS). RS232 tunneling mode can be configured via the remote control parameters defined here-after. 6.7. Configuration of remote control and local control To setup these parameters, go to menu «​Settings​», «​Remote Control​». Remote control of PYKO through TCP commands 13

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 at the end of this document. Local control of PYKO through commands sent via the serial port PYKO can be controlled through ASCII commands sent through its RS232 port. To enable this mode, go to section « ​Serial Link​ » and select « Control » for parameter « ​Serial link mode​ ». The ASCII commands are described in a separate document. 6.8. Tunneling of auxiliary data 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. 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 ​». 14

- ​Gateway TCP client​ : in this mode, PYKO-out 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-out 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-out 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​ ». 15

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​ ». PYKO-out 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​ ». 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. 6.9. Configuration of decoding priority levels The sources PYKO-out can decode are : ○ an RTP IP audio stream. Supported audio formats are PCM, mp3, AAC-LC or G711. ○ HTTP IP audio stream (shoutcast or Icecast) in mp3 . ○ M3u playlists with mp3 sound files, stored on the USB memory stick. PYKO-out can decode these sources according to 3 priority levels (priority1 being the highest priority, and priority 3 being the lowest). At any time, PYKO-out decode the highest priority which source is present. This allows the following : - getting automatic backup in case a source is lost (typically an IP stream). - automatic switching to a high priority message while decoding a medium priority (background music for instance). The configuration consists in declaring a source for each necessary priority level. Rdaio broadcasting example: - Priority 1 = RTP stream - Priority 2= HTTP stream (fir st backup is an internet radio) - Priority 3= USB Playslit (second backup in case no stream is received) Go to menu « ​Audio​ », and select the priority level to configure. Priority level 1 : Stream priority #1 16

This is the highest priority. This priority can only decode an RTP stream. The stream parameters are the following : ●URL ​: URL of the RTP stream to be decoded. Syntax : rtp://addressIP:Port For a unicast stream, enter 0.0.0.0 in the IP address, and give the UDP port. Ex : rtp://0.0.0.0 :5040 For a multicast stream, give the multicast IP address and the port. Ex : rtp://224.0.0.100 :50040 ●Activation​ : Select ​Enabled​ to enable this priority level. Select ​Disabled​ if you do not want to use this priority, in which case PYKO-out never decodes this priority. ●Channel Mode ​: Significant only in PCM format. Select ​Mono​ or ​Stereo​. ●Audio Format ​: Select the format of the audio data of the IP stream to be decoded (mp3, PCM from 8 kHz to 48 kHz, G711 A-law or µlaw). In case the configured format does not match the received audio format, PYKO-out interprets this as an error and does not decode the stream. As a consequence, PYKO-out switches to the immediately lower priority (Stream priority level “n+1”). ●Latency​ : this corresponds to the input buffering which is necessary to compensate the network jitter. The higher the jitter, the higher the buffering value. Latency values are about: Lat = 1 32ms Lat = 2 64ms Lat = 3 96ms Lat = 4 128ms Lat = 5 192ms Lat = 6 254ms Lat = 7 384ms Lat = 8 512ms Lat = 9 640ms Lat = 10 768ms In mp3, latency value must be at least equal to 6. In PCM, latency values lower than 3 can be used on high performance networks (LAN). ● Default Volume ​: default attenuation applied to the output, from 0 dB to -40 dB. ● Minimum volume​: maximum attenuation that can be adjusted from the « Live » WEB page. ● Maximum volume​: minimum attenuation that can be adjusted from the « Live » WEB page. ● Balance​ : Left / Right balance. Centred by default. Click on ​Apply​ to confirm the configuration. 17

Priority level 2 : Stream priority #2 This priority level can be used as follows: ●first backup level in case RTP stream defined in priority 1 is lost. This backup can be and RTP stream, or HTTP stream. ●standard priority (typically background music in an hotel). Priority 1 is then reserved to announcements. ●For decoding a stream selected among several streams received on this priority (kind of IP audio tuner). The stream to be decoded (more exactly the receiving port) can be selected through ASCII commands (through TCP or RS232), from the « Live » WEB page by selecting the receiving port, or from a GPI (see ​GPIs configuration)​. ●Local playlist (stored in folder \bk of the USB storage), which playback is triggered when priority 1 is lost. Parameters which differ compared to priority 1 are the following : - ​URL ​: URL of the RTP stream, HTTP stream, or name of an m3u playlist. Syntax for a unicast RTP stream : rtp://0.0.0.0:Port (ex : rtp://0.0.0.0 :50040). Syntax for a multicast RTP stream : rtp://IPaddress :Port (Ex : rtp://224.0.0.100 :50040). Syntax for an http stream (shoutcast / Icecast): http://servername:Port/Mountpoint (Make sure to enable the DNS from the Settings page). - ​Time out​ : This is the time granted to PYKO-out to catch the HTTP stream. If this time is exceeded, the http stream is considered as absent, and PYKO switches to priority 3 if it is defined. - ​Nbr streams​ : defines the number of RTP streams that can be received on priority 2. These streams must be received on UDP ports which values are incremented by 2 starting from the port value defined in the URL. Example: - URL: rtp://0.0.0.0:5004 - Nbr streams = 4 => 3 additional RTP streams are sent to this PYKO-out (unicast), on ports 5006, 5008, 5010. This also works with a multicast IP address, in which case all the streams are sent to this same multicast address. 18

Priority level 3 : Stream priority #3 This priority level has the same parameters as priority level 2, with exception of the number of streams. Backup playlist must be stored in folder /bk of the USB memory stick. 6.10. Real time control (Live) via WEB page The “Live” WEB page allows changing in real time (without restarting PYKO) the output level, as well as the stream to be decoded on priority level 2 in case several streams have been declared. ● Current Stream​: allows selecting the port of the stream to be decoded on priority 2. ● ​Select Stream​ : allows the validation of parameter ​Current Stream​. ● Level --​ : each ‘mouse click’ on this button applies an additional attenuation of 1 dB on the decoded stream. The maximum attenuation is defined in the priority page. ● Level ++​ : each ‘mouse click’ on this button applies an additional gain of 1 dB on the decoded stream. The maximum attenuation is defined in the priority page. ● Mute ON​ : a mouse click on this button mutes the audio outputs. ● Mute OFF​ : a mouse click on this button mutes the audio outputs. 19

6.11. Display of PYKO-out status The status of PYKO-out is displayed on the top left of the WEB pages. Displayed information are : Backup Playlist Present : ​allows to know whether the defined playlist is detected or not on the USB memory stick. Stream priority level:​ allows to know the priority level that is being decoded. Listening audio​: allows to know the source that is being decoded: URL, or playlist name. Audio format:​ audio format that is being decoded. Volume & Balance​: current attenuation on the audio outputs. Mute​: mute status on the outputs (ON / OFF). Out Peak Meters​: instantaneous peak-meter value of the decoded audio signal, given in dBFs (0 dBfs being the maximum value). Jitter margin :​ indicates the jitter variation that can be supported on the current stream. If the displayed value goes to 0, it is necessary to increase the parameter « Latency » from the “Stream priority” page associated to this stream. 6.12. M3u playlists and mp3 sound files on the USB memory stick PYKO-out supports USB memory sticks FAT16 formatted. M3u backup playlists and associated mp3 sound files must be located in folder \bk. M3u playlists and associated mp3 sound files that can be triggered through ASCII commands must be located in folder \an 6.13. Firmware update PYKO-out is delivered with a “Playout” firmware ready to run. This firmware does not support the USB memory stick, and is to be used with Digigram AudioManager middleware. For all applications that require the USB memory stick, it is necessary to apply the “Playout-extended” firmware. PYKO firmware are available from Digigram WEB site, PYKO-out support page. Download the firmware file. Then, from the PYKO-out WEB page, go to the , , and click ‘Browse’ to indicate the location of the downloaded firmware file; click on the ‘Upload’ button.

6.14. 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. 6.15. PYKO-out in ‘stand-alone’ mode You can now access the embedded html pages that will allow you to configure the device. 22

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. 6.16. 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. 23

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. 24

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). 25

Nominal output level Jumper positionning This setting defines whether the nominal level of the analog signals is either +18 dBu or +4 dBu (“Professional”). Default factory setting is +18 dBu for all outputs. The settings act upon the nominal output level. Having located the pair to modify in the overview (​previous page​), set the jumpers according to the above illustrations to match the requirements of your system. 31

11. 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. RTP payload type Audio Format 0 μ​-Law, 8bit, mono, 8kHz 8 A-Law, 8bit, mono, 8kHz 10 PCM 16bit, MSB first, signed, 44.1 kHz stereo, left channel first 11 PCM 16bit, MSB first, signed, 44.1 kHz mono 14 MPEG audio 96 PCM, 16bit, MSB first, signed, 8 kHz mono 99 PCM, 16bit, MSB first, signed, 24 kHz mono 102 PCM, 16bit, MSB first, signed, 32 kHz mono reserved 103 PCM 16bit, MSB first, signed, 48 kHz stereo, left channel first 111 PCM, 16bit, MSB first, signed, 12 kHz mono 127 Other formats* Payload types 0, 8, 10, 11 and 14 are defined by the RTP standard. Digigram defines assignment for payload types 96 to 127 (dynamic payload types) in the above tables. * For a PCM 24 bits stream coming from a PYKO-in, and from firmware version v020, payload is 113 instead of 127. 32

12. APPENDIX E: AUDIO CONNECTORS The audio inputs/outputs of PYKO-out come on a terminal block connector with two lines of three pins each (= two counterparts). [] Pinout Pin Signal 1 GND 2 OUT 1- 3 OUT 1+ 4 GND 5 OUT 2- 6 OUT 2+ 33

13. ANNEXE F: GPIO CONNECTORS PYKO-out features four TTL 5 V compatible GPIs and four relay GPOs. The counterparts are provided.
