General Information

Continuing a tradition for products brought about by creative thinking and technological precision,
the DB46 – Compact DAB/DAB+ Monitoring Receiver slots in seamlessly within DEVA’s range
of monitoring tools by offering another dimension of accuracy and cost-effectiveness. While also

retaining the dening characteristics of the DEVA brand, this revolutionary product is specically

dedicated to one of the major areas in the industry - Digital Audio Broadcasting, and fully meets
the ETSI EN 300 401 DAB standard.

Along with the guaranteed quality of performance, a crucial asset of this product is its design
– compact, smart and extremely practical. Proving that practicality does not come at the cost of

efciency, the DB46 boasts a wealth of capabilities and superb features. It has a highly-selective

DSP-based tuner, supports the latest DAB & DAB+ standards.

What is more, it offers support for Program Associated Data (PAD), as well as all standard
bitrates and VBR, and automatically displays live metadata. While the signal is being monitored
and logged, the DB46 measures the following DAB signals: RSSI, SNR, CNR, FIC Quality, FIB
Errors, FFT Offset and the Left & Right Audio level values and stores them, thereby allowing
for future analysis. A standard FTP client is all that is required for the collected data to be easily
downloaded.

The BandScan function of the DB46 presents an overview of all DAB/DAB+ signals available,
plus their RF signal strength. BandScans are possible within any section of Band III. The generated
spectrum diagram shows the RF Level vs. the channels.

Another impressive feature of the DB46 is the fact that the tool guarantees no interruption
of the broadcast signal. This is achieved through the provided local alarm options and online

notications via rear-panel alarm GPOs, E-mail and SNMP in case there is audio loss or change in

the DAB signal and the Left and Right Audio Levels. This allows for a fast response on the part of
the maintenance staff so that prolonged signal loss can be prevented.

Users can also easily control and set up their DB46 unit remotely through their PC, tablet or
smart phone via a standard web browser; iOS and Android devices are also supported.

Compact and affordable, with a remarkable set of technical characteristics, DEVA’s DB46 is a

denite must-have for accurate, dependable DAB/DAB+ monitoring.

APPENDIX A

ALARM TRIGGERS

After collecting all the data, the DSP-based core compares the values measured with the

predened by the user threshold levels, for all the alarms monitored. In case that a parameter
is beyond limits, the device will initiate the sending of an alarm notication via the selected

communication path. All the alarm events are stored in the device’s log. It is essential that, if there
is a very short fault of the signal, with duration shorter than the ‘alarm trigger time’, the device
would not trigger an alarm.

There are several Alarm Triggers for the following parameters: RF, MPX, MPX Power, Left/

Right Audio, RDS Group loss, Pilot and RDS levels. An option for dening different limits for

each of the parameters is present. All these values, the ‘trigger time’ and the ‘release time have to
be assigned separately for each of the alarms.

When an observation event takes place, the Alarm Trigger’s State will refresh, if necessary.
Should we consider an instance when the Alarm Trigger is in Idle state, having in mind that an alarm
is not triggered immediately when a parameter level passes beyond threshold: If the parameter
level becomes stable, within Thresholds, and the Alarm Trigger Time is not elapsed, then the
Alarm Trigger remains in Idle state. If the Alarm Trigger Time expires and the parameter level is
still beyond limits, the Alarm Trigger would change its state to High/Low. This would result in

predened actions - Alarm Notications (E-mail, SMS, SNMP trap) and Save a Log Record. The

state will not be immediately switched into Idle when the parameter stabilizes, within Threshold
levels, not up until the ‘Alarm Release Time’ is elapsed. Meanwhile, if the parameter crosses again
any Threshold, the Alarm Trigger will remain in Active state. If the parameter remain within the
Threshold levels and the Alarm Release Time expires, then the Alarm Trigger would switch into

Idle state and again predened actions would be initiated.

If the RDS Group has not been received within the Alarm Trigger Time, the state would be
changed into Active. If the Active state and the Release Time have elapsed and the RDS Group is
received, the state is changed to Idle. Should the RDS Group is received before the Release Time
is elapsed, the state would remain Active.

APPENDIX B

GSM MODEM OPTION - FEATURES AND USAGE

The described Features and Usage of the GSM Option is compatible with following DEVA Units:

- DB46 – Compact DAB/DAB+ Monitoring Receiver

- DB7012 – Professional DSP-based DAB/DAB+ Monitoring Receiver

The DEVA DAB/DAB+ Monitoring receivers supports a very wide range of GSM Modems.
However, we suggest the usage of the following model - Sierra Wireless AirLink. This is the
modem that is provided from DEVA Broadcast if the feature has been ordered along with the
DEVA Units.

The GSM modem model is directly PIN to PIN compatible with the DEVA Units GSM
Modem’s connector, and by simply using a direct cable, you will have not any troubles with the
data communication and audio insertion.

Before connecting the GSM Modem to the DEVA Unit, it is necessary to set up the parameters
for normal operation. Please bear in mind that:

• GSM modem does not have an automatic detection of the baud rate (AUTOBAUD
function). The most important thing is to set up the GSM Modem communication settings.
The Communication speed must be 9600 bps, Data Bits: 8; Parity: None; Stop Bits:1.

• The SIM Card PIN code must be disabled in order to avoid a conguration problem of the

modem. We suggest you to do this procedure using a GSM phone device of choice. This
will save you a lot of time for reading the GSM Modem documentation. In case you decide
to do that using the GSM Modem please refer to its User Manual for details.

IMPORTANT: Once the GSM modem is properly installed, the DEVA Unit must be pre-

congured to receive messages from up to 5 authorized numbers. This can be made via the WEB
interface of the device. Upon successful installation, a notication message will appear on the
unit’s LCD/OLED screen (if such is available). Using this screen you can nd the best place with

good GSM Network coverage for the installation of the GSM modem.

NOTE: For information, how the DEVA Unit can be accessed via the WEB Interface, please

refer to the respective quick user guide for the device in question. All the documents are available
at www.devabroadcast.com/downloads

REMOTE AUDIO LISTENING

Type the following text and send it as SMS to the Device’s GSM number:

Listen F

Upon receiving your ‘Listen’ request via SMS, the device will call you back. When you take

the call, you will hear the audio on the service F

IMPORTANT:

F is the service number (preset number set in the device).
For example: “Listen 1” or “Listen 6”.
Do not include leading zeroes such as “Listen 06”

REMOTE STATUS REQUEST

The DEVA Unit can send you a report with the values of the most important parameters at any
time. Upon receiving your request via SMS, the device’s tuner will be adjusted on the requested
service number and will make measurement of all the available parameters. Once the procedure
is completed, an SMS message will be generated and sent to the requestor’s GSM. Command
Example:

Status F

IMPORTANT:

Where F is service number (preset number set in the device) to Tune.

Do not include leading zeroes such as “Listen 06”

The Device will shortly respond back with SMS with the available parameters.

APPENDIX C

HOW SHOULD I CONFIGURE THE CONNECTION BETWEEN MY
DEVA DEVICE AND AN FTP CLIENT?

In order for a connection to be established the following setting should be applied:

1. FTP Server Settings

The built-in FTP Server has four important parameters that should be congured: Command

Port, Data Port, User name and Password. These parameters are to be used in the FTP client’s

connection conguration. Further information on how to change the FTP Server’s settings and

their respective default values can be found in the device’s User manual.

WE RECOMMEND the usage of FileZilla (https://lezilla-project.org). This is a widespread

open source software distributed free of charge, hence available for downloading from the Internet.

NOTE: The FTP Server can manage only one connection at a time. The FTP Server works in

Passive mode. Hence, the FTP Client should also be set in passive mode.

2. IP Router and Port Translation Settings

If the connection to the device is made through a Network address translation (NAT) router or

rewall, the port forwarding feature of the router should be congured. The port forwarding is
usually set in the rewall section of the router’s menu. As each router has different port forwarding
procedure, we recommend you to refer to its complete manual. To allow proper data ow through

the router, the FTP Command and FTP Data ports should be open.

NOTE: The FTP port numbers to be used in the port forwarding feature conguration can be

found in the device.
