4 RELEASE NOTES

4.1 Version 3.06c

What’s new in version 3.06c

● Dual streaming: the redundant stream can now be delayed up to 3 seconds instead of 1second in previous

firmware versions

● Save/load configuration: the full IQOYA configuration can now be remotely downloaded/uploaded to/from

IQOYA, in addition to be saved to the SD card. With previous firmware versions, it could only be saved to the SD

card. The full configuration file is now a compressed file (.tar).

● Silence detection: silence detection on the decoded IP audio stream is now available, with silence criteria and

signal criteria. An alarm is associated to it.

● Automatic disabling of a decoding priority upon silence detection. Each decoding priority can be configured to be

automatically disabled upon silence detection in the decoded IP audio stream.

● GPIOs: Status of GPIs and GPOs is now displayed on a WEB page.

● GPO: It is now possible to define a status that each GPO takes when the IP audio stream is lost.

● GPO: a GPO can be used for tunneling or for signaling an alarm. If it is configured for both tunneling and

alarming, it only reflects the alarming.

● A digital level can be adjusted for each decoding priority

● Possibility to load the configuration on the SD card when rebooting IQOYA.

What’s new on blue IQOYA *LINK and LINK/LE

IQOYA *LINK - IQOYA *LINK/LE

USER MANUAL

● Audio source of the encoder can be a Livewire, AES67, or Ravenna IP audio stream.

● Audio destination of the decoder can be a Livewire, AES67, or Ravenna IP audio stream.

● Synchronization on a livewire clock, PTP clock

● Possibility to generate a PTP clock

● Synchronization on the AES/EBU input

● Possibility to configure an AES bit transparent transport (by using PTP between encoder and decoder)

What’s new in firmware 3.00?

● Four decoding priorities instead of three.

● New menu Preferences/Audio with three sub-menus: Audio in/out, Audio setup, Clock

● Possibility to receive an IP stream, and to transcode and stream it, thanks to the internal “Audio bus”.

Receive section decodes the IP stream and sends the decoded audio to the internal “Audio bus”.

Send section takes audio samples for the internal “Audio bus” and encodes them and streams over IP.

● Possibility to receive a Livewire stream and to encode and stream it, in standard Livewire mode (240 samples

per frame).

● Possibility to decode an IP stream and to send the decoded audio as a Livewire

● Possibility to synchronize IQOYA on its AES/EBU input.

● Possibility to synchronize IQOYA on a network clock (PTP AES67, Livewire)

● Possibility of AES samples transparent transport between the encoder and the decoder without external GPS

synchronization.

● Adjustable digital level on audio received on each decoding priority.

● New SNMP variables for allowing an SNMP supervisor to get the maximum jitter over a period of time.

Each decoding priority (1 and 2) has 3 new SNMP variables:

- max temporary jitter for primary stream : disReceiveSourceMetricsAutoResetJitterPrimary

- max temporary jitter for secondary stream : disReceiveSourceMetricsAutoResetJitterFEC

- max temporary jitter for primary& secondary streams : disReceiveSourceMetricsAutoResetJitter

A GET on « disReceiveSourceMetricsAutoResetJitterPrimary » of priority 1 returns the max jitter for primary

10

IQOYA *LINK - IQOYA *LINK/LE

USER MANUAL

stream of priority 1 since the last GET, and saves the other values for the priorities 1 and 2, and resets all the

temporary jitters.

The other values on both decoding priorities can be read (GET) right after the first GET.

The counters evolve till the next GET on the temporary jitter for primary stream of priority 1.

● Persistent log file

this feature requires the presence of an SDHC card in the unit. The log file is written at the same time in volatile

memory and on the SDHC Card. In case the unit is powered OFF and ON, the log file is copied from SDcard to

the volatile memory when the unit restarts, so that the log file is visible from the WEB interface with all the traces

created before the power failure.

IQOYA *LINK - IQOYA *LINK/LE

USER MANUAL

6 INSTALLATION

6.1 Connecting the IQOYA *LINK or IQOYA *LINK/LE

It is recommended to establish all connections before powering the device up.

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.

After switching ON the codec, it takes about 30 seconds before it is operational.

We recommend that the first connection to the IQOYA codec is done on a LAN. The default IP address of the Eth0

interface (formerly IP audio) is 192.168.0.100. Make sure all other devices connected to this LAN are in the same

subnet and have different IP addresses (this includes the PC from which you will connect to the IQOYA codec to

configure it).

To connect the IQOYA codec to the LAN, connect the Ethernet cable to the RJ45 port labeled “IP AUDIO”.

Notes: The default IP address of the “Eth0” port (formerly “IP audio”) is 192.168.0.100. This port is enabled by

default.

The default IP address of the “Eth1” port (formerly “IP BACKUP / CONTROL”) is 192.168.1.100. This port is

disabled by default.

IQOYA *LINK and IQOYA *LINK/LE embed a web server that enables you to control it through your favorite Internet

browser.

6.2 Connecting the IQOYA *LINK or IQOYA *LINK/LE to an

xDSL network

Like for any other IP equipment, it is highly recommended that IQOYA is not connected directly to the xDSL

network. A router/firewall should be used to avoid attacks from “malware”.
