2General Description.
MVDS2 is the new version of Elber Multichannel audio/video distribution system; it has been designed to transmit or
transfer combined DVB-S/S2 carriers or full satellite transponders at Ku-band frequencies.
MVDS2 is a fully weatherproof IP65 housing suitable for outdoor installations in harsh environments, available in two
version, standard or high power; the standard version hosts GaAs FET transistor as final stage, while the high power
utilizes GaN FET. GaN technology achieves higher efficiency and superior performances in terms of linearity compared
to the GaAs.
The system is protected with automatic squelch of final stages in case of critical temperature or power overload.
The management and monitoring of the equipment can be achieved through a very easy and intuitive web interface.
3Installation.
▪Unpack the equipment and check first check if there are any damages due to the transport.
▪The box should contain:
oThe MVDS2
oOne envelope with customer’s default password and user manual
oOne power supply connector
oOne M&C connector
▪Install the equipment on a mast.
▪The equipment must be correctly grounded, to guarantee a secure functioning.
▪Connect to the correct power voltage reading the information on the manual or on the label attached to each
equipment, containing the serial number.
▪Connect the network cable to the plug. The last used configuration will be loaded.
▪Setup the equipment according to the needs consulting the user manual.

5Web interface.
MVDS2 is equipped with a WEB interface for an easy and intuitive monitoring and equipment configuration. The
connection to Web server can be achieved through dedicated cable directly to the outdoor unit.
With a common Web browser (like Internet Explorer, Mozilla Firefox, Google Chrome, Opera, Safari…) it is possible to
check equipment status and verify performances even remotely simply writing in the address bar the IP address of the
equipment. To check the IP address, please refer to par 5.1.
Important Note: Default IP address is 192.168.10.150.

The equipment offers an operation log service that can be checked in this tab of the web interface.
In left part of the web page, the form concerning available logs is present, grouped by:
-Daily report
-Last day
-Last week
-Last month
To avoid huge memory usage and to accelerate log loading and showing, it is recommended to delete old records
using Erase until form and selecting desired interval (Figure 12).
In central part of the page, log messages are reported, organized in a table that can be ordered, filtered and resized in
terms of number of rows per page.
Records belong to 4 different categories are shown with different colors for user facility:
1. Messages
2. Configurations
3. Alarms
4. Warnings
Every record has a time, a description and an origin; an alarm event is described in appendix with OCCURRED tag,
while the alarm condition recovery is a Message with appendix RECOVERED. Records can be ordered in every column
and filtered (with related checkbox).
Log can be saved on user laptop as .xls, .xml, .csv, .tsv, .html or JSON file clicking on related icons.
