Embedded Web Server
Configuration
There are five sections under the ‘Configuration’ tab, these are as follows.
• Network
• Front Panel
• Audio Routing
• GPIO Settings
• SNMP Settings
Network
The Network page shows the current configuration of the control port
which is used to access the devices web server. The friendly name and
security options can also be set here.
Friendly Name
The friendly name identifies the unit on the network. It is a good idea to
assign a user name or location as this is easily recognised by other users.
The default friendly name is made from the device ID and the 7-digit
product serial number i.e. AVN-CU2-1234567 or AVN-CU4-1234567. The
friendly name can only contain letters, numbers and hyphens although it
cannot start or end with a hyphen.
Password
Fig 6-4: Device Name & Security
In order to prevent other users connected to the same network from
modifying the configuration of the device it is possible to protect your
device with a password. The password may be between 4 and 8 characters
long and may only contain numbers and letters.
Retype Password
In this field a password must be retyped, this is to make sure you didn’t
accidentally enter your intended password incorrectly.
Removing Password Protection
Password protection can be removed from a device by clearing both the
‘Password’ and ‘Retype Password’ fields and clicking submit.
HTTP Port
The HTTP port number can be set to any integer from ‘1024’ up to and
including ‘65535’, or to ‘80’ the default value. The value entered determines
which port the web server on the device will use. When the port number is
modified the unit will be restarted automatically. To view the web pages of
a device with a modified port number, the port number must be specified
in the address bar of the web browser after the IP address and separated by
a colon.
For example, if the HTTP port of a unit is set to ‘1024’ and the IP address of
the unit is ‘192.168.0.100’ then ‘http://192.168.0.100:1024’ would need to
be entered into the address bar of the web browser.
When the port is set to its default value of ‘80’ a port number doesn’t need
to be specified when accessing the web server.
The web server on the unit is advertised as an Avahi / Bonjour service so
tools like Sonifex Service Discovery or avahi-browse will be able to discover
the address and port number being used by the web server on the unit.
