Power backup system
Several applications, that can be launched from the Radio all in one portal or from the front panel, give
access to those functions, each with its own user manual :
¾
Radio All In One: main application which includes RDS, audio backup, transmitter
configuration, unit status and system configuration.
¾
Digiplexer Sound Process: sound processing application,
¾
ScriptEasy v.2.3.7 and MasterView v.1.3.1*: remote control and automation application
and creation of end-user views.
Whether remote or local, these applications work in similar ways.
Layout differences (login window, virtual keyboard) exist and are described in the applicable manual.
* Only the MasterView Viewer is available from the front screen application.
To ensure optimal performance, do not start 2 remote applications at the same time.
1.1.3. A few words about RDS
The RDS system is governed by the European standard CENELEC EN50067. This system has been
originally designed, to provide the functions directly associated with radio broadcasting and is briefly
described below:
¾
Automatic changing of frequencies
¾
Display of the name of the station on the radio
¾
Display of radio text for tuners
¾
Use of pre-select buttons on radios to memorize a station instead of its frequency.
The RDS system transmits the data via a 57 kHz sub-carrier. Audemat’s reputation has grown due to
its specialization in the RDS field which makes it a preferred supplier for numerous public and private
operators using RDS.
Over the years, RDS has been expanded and is now also used for data transmission which has little
to do with the program of the radio station:
¾
Transmission of traffic data
¾
Paging systems
¾
Remote control of equipment
¾
Transmission of differential data for GPS
