INSTALLATION AND CONFIGURATION

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

IQOYA codec 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 “IP AUDIO” port (Eth0) is 192.168.0.100. This port is enabled by default.

The default IP address of the “IP BACKUP / CONTROL” port Eth1” is 192.168.1.100. This port is disabled by

default.

IQOYA *LINK and IQOYA *LINK /LE support three categories of users: Administrator, User, Read only

“Administrator” category

A user from the “Administrator” category has all the access rights on the WEB pages.

The login to the embedded WEB server as “Administrator” is:

- username: iqoya

- default password: iqoya

Password can only be modified when logged as Administrator.

“User” category

A user from the “User” category has limited access rights. “Write” access is limited to the audio parameters

(audio format, source/target IP address and UDP port).

The login to the embedded WEB server as “User” is:

- username: user

- default password: user

Password can only be modified when logged as Administrator. Old password must be entered before entering

the new one.

“Read-only” category

A user from the Read-only category only has “Read” access rights. He cannot modify a single parameter of the

codec.

The login to the embedded WEB server as “Read-only” is:

- username: guest

- default password: guest

Password can only be modified when logged as Administrator. Old password must be entered before entering

the new one.

Remote configuration through html pages

• Open a web browser and type in the address bar the IP address of the IQOYA codec in https mode and hit

the ‘Enter’ key.

• The WEB browser displays a message about security certificate. Select the option to continue with this WEB

server.

• Enter the username and password. For a first configuration of the codec, use the default administrator login

(username: iqoya, password: iqoya).

You can now visualize the Web pages that enable you to configure the device.

HTTP bandwidth limitation

In case the network bandwidth is limited and the IP audio stream takes almost all the network bandwidth, the

HTTP traffic generated when accessing the WEB pages may disturb the IP audio frames transmission on the

network, because the total bandwidth necessary for the IP audio stream plus HTTP traffic may exceed the

available network bandwidth.

To avoid this problem, IQOYA offers the possibility to set a bandwidth limitation for the HTTP traffic. This is

available from the Service menu, HTTPS.

Bandwidth limitation: default value: ‘No’.

Set this parameter to ‘Yes’ to define a bandwidth limitation for the HTTPS traffic.

Maximum bit rate (kbit/s): enter here the maximum bit rate allowed for HTTP traffic from the IQOYA to the

computer hosting the WEB browser. As a consequence, the HTTP upload traffic is also limited, and it takes

longer to display the WEB pages.

The lower the ‘Maximum bit rate’ value, the slower the WEB pages display.

Note: when loading all the WEB page (typically first access to the WEB page), there may be an additional peak

of HTTP traffic exceeding the limitation of +25%. As a consequence, it is recommended to lower the

maximum bit rate value to take into account this peak.

Example:

Network bandwidth limited to 2 Mbits/s

Audio format: PCM stereo 16 bits 48 kHz

FEC: +10%

IP audio bit rate (including FEC): 1 834 800 bits/s

Maximum value to be set for parameter ‘Maximum bit rate’: 130 kbits/s
