Changing the Device Settings
General Configuration Settings
Introduction
The general configuration settings of the XDQA24 system are categorized on the
Device page of the web browser user interface. These settings are:
Device Settings
QAM Encoding Type parameter
The XDQA24 system can participate in ITU-A (DVB), ITU-B (OpenCable), or
ITU-C (Japan) applications. Therefore the XDQA24 has to be set to the correct
QAM encoding type.
Note: After changing the QAM Encoding Type parameter all settings located on
the Input, QAMs, and Device page will be reset to the default values for the
selected QAM encoding type.
Device name and Device location parameter
Both the Device name and Device location parameter can be used to facilitate the
identification of the XDQA24 system in the application. A name and location of
maximum 50 characters can be given and can't contain the following characters: $,
@, [, ], {, }, %, ", =.
Tip: These parameters appear in the title bar and in the header of the web
browser user interface.
Keep Alive Packets Settings on the GbE ports
For unicast IP streaming (1 sender and 1 receiver) the devices connected to the
XDQA24 system need the knowledge of the MAC address of the system. Therefore
the XDQA24 system broadcasts IP packets containing the MAC address together
with the IP address. The devices at the other end of the link can use this information
to build their ARL tables. The parameters for this Keep Alive feature are:
Enabled parameter
This parameter enables or disables this feature.
Repetition Rate parameter
This parameter determines the time between two successive Keep Alive IP packet
broadcasts. A repetition rate between 1 and 999 seconds can be entered.
