General Information
Radio Explorer III DAB adds another dimension to DEVA Broadcast’s already spectacular range
of DAB/DAB+ products. This is an advanced coverage survey mobile tool in full compliance with
the ETSI EN 300 401 DAB standard. Among its most important advantages are the two powerful
DAB tuners, which account for the unprecedented accuracy and reliability to this product.
Radio Explorer III DAB allows you to monitor up to 10 services within the DAB ensemble
with predened acquisition time in a round-robin scheduler and stores the measured parameters in
a log le for further analysis through the DEVA Device Manager software.
It oers support for Program Associated Data (PAD), as well as all standard bitrates and VBR,
and automatically displays live metadata. As a tool of immense precision, it also measures the
following DAB signals: RSSI, SNR, CNR, FIC Quality, FIB Errors, FFT Oset and the Left &
Right Audio level values.
The BandScan function of the Radio Explorer III DAB presents an overview of all DAB/DAB+
signals available, plus their RF signal strength. BandScans are possible within any section of
Band III, whereas the generated spectrum diagram shows the RF Level vs. the channels. Another
great asset to this tool is the Loudness meter, which can be shown as dened by ITU BS.1770-4
and EBU R128 recommendations, as the product supports both.
As a matter of course, our aim with Radio Explorer III DAB has once again been to make
sophisticated, high quality equipment easy to use. This product has a high-resolution graphical
OLED display with front panel navigational buttons and soft buttons for quick access to the
device’s various functions. Another option to control the unit is via the built-in Web server - a
standard web browser can be used to monitor its status or to make some adjustments. iOS and
Android devices are also supported. The Main Screen of the WEB Interface shows all mandatory
parameters represented as LED bar graph readings.
The DEVA Device Manager Software, supplied free of charge, also allows for quick and easy
connection to the device.
Another elegant solution in our DAB/DAB+ line, the Radio Explorer III DAB brings precision,
eectiveness and the customary DEVA quality.

NETWORK SETTINGS
After connecting the network cable the Led ‘LAN’ located on the rear panel must be ON or
ashing. The next and most important step for conguration is the adjustment procedure of the
Network Communication. The settings shown below are Default Network Settings:
DHCP Enabled
IP Assigned by DHCP
Mask Assigned by DHCP
Gateway Assigned by DHCP
DNS Assigned by DHCP
HTTP Port 80
The Radio Explorer III DAB is controlled trough a build in WEB Server and a standard Web
browser can be used to monitor its status or to make some adjustments. To operate the device you
need to know its IP Address. In case you are not aware of it, you can use the Network discovery
feature at Local networks.
1. Connect the device to the local network or to the Internet by LAN cable;
2. Open a new WEB Browser and enter the device IP address in the address eld then press
[Enter]. A new WEB browser with Radio Explorer III DAB’s Main window will appear;
3. To access the device’s settings press [Settings], the default values are username: admin and
password: pass.
NETWORK DISCOVERY
If you have already enabled this function on your computer just open a new Explorer bar and
click on Network. The device must be displayed. If not follow the instructions below.
1. Open Advanced sharing settings by clicking the Start button, and then on “Control Panel”.
In the search box, type “network”, click “Network and Sharing Center”, and then, in the left
panel click “Change advanced sharing settings”.
2. Select your current network prole.
3. Click Turn on network discovery, and then click Save changes. If you’re prompted for an
administrator password or conrmation, type the password or provide conrmation.
4. To access the device open a new Explorer bar and click on Network. If you have successfully
enabled the network discovery option, the device will be displayed. Double click on
Radio Explorer III DAB will open a new WEB browser with the Main window.
5. To access the device’s settings press [Settings], the default values are username: admin and
password: pass.
NOTE: If the port is dierent than the default one (80), it is necessary to specify it, for example:
http://192.168.1.2:9000
ATTENTION: Depending on Internet Protocol Settings, the assigned IP address may not be
visible outside your local network, thus the device may be accessed only within that network.
Consult with your network administrator for the appropriate IP settings.

Basic Setup
OLED DISPLAY
Radio Explorer III DAB has an easy to read, high-resolution OLED graphical display that
visualizes all measurements of the received signal and settings. Upon switching it on, the Company
Logo and model of the device will be displayed. After a few seconds the start-up screen will
disappear, replaced by the main screen. This is the starting point of the navigation process.
Radio Explorer III DAB’s OLED display has three function areas: header, soft buttons and
main screen working area.
HOW TO CHANGE DEVICE PARAMETERS
Set-up menu title
Shows the path to the currently selected menu. Note that the parameter should be included in
the settings menu title. For example: Setup> Communication> HTTP> Port is dierent from
Setup> Communication> FTP> Data Port.
Navigation area
Selection of branches / parameters is made in this area. The selected item is highlighted. All
parameters are listed on the left side of the navigational area. All parameter values are displayed
on the right side against the parameter name. As the branches have no values associated, tree dots
are shown instead. This indicates that a transition to a sub-menu is available.
Front panel buttons usage:
[OK] – Depending on the selected menu element can perform dierent actions:
• Menu branch – transition to selected sub-menu will be made;
• Menu parameter – when a name of a parameter is highlighted pressing [OK] will highlight
the value and switch to edit mode;
• Menu complex parameter (such as Alarm) – the parameter editor screen will be shown.
[UP] / [DOWN] – If edit mode is active, the value of the selected parameter will be changed.
Otherwise, are used for navigation through the menu;
[LEFT] / [RIGHT] – Change the selection when the parameter value is in edit mode;
[SB4] – Return one level up or cancel edit mode.
