General Information

The DB4402-V2 – Dual FM Monitoring Receiver is a superb and highly practical combination
between a logger and a streamer which allows you to easily and accurately monitor and store all
important parameters of the FM signal while simultaneously giving you the opportunity to listen to
a constant, uninterrupted audio stream. The synchronized performance of both major functions is
at the core of the idea for this model, as well as the unit’s major asset. You can listen to the selected
audio feed at the same time as the logger campaign is running. The design of this device relies
on simplicity coupled with functionality to offer customers the opportunity of a single solution to
both tasks.

Providing the stable, dependable operation characterizing all DEVA products, the DB4402-V2
is fully DSP-based, with a built-in oscilloscope and an RDS/RBDS decoder with a BER meter.
It also permits users to set alarms for RF, MPX, Pilot and RDS signal via email, SMS or SNMP.
What is more, the TCP/IP and GSM connectivity provides easy remote control, monitoring and
listening to the radio signal from any location.

The device offers a “Restore Factory Defaults” option and easy update of the rmware. It is

an advanced solution giving customers a number of advantages and top all-round, multi-faceted
performance as both a monitoring tool and a streaming device.

The MPX page shows the baseband MPX deviation as a function of deviation in kHz over the

observation period. The graph immediately shows modulation density.

There is also a rolling 60-minute graph of the MPX power with average indicator, measured in

dBr. The MPX Power is calculated continuously with an integration window of 60 seconds and

a new sample every 20 seconds. Therefore, the rst sample is available 60 seconds after tuning.

The rule of MPX Power provides to measure the modulation power which is seen equal to
modulate signal electric power, for one minute time period and to compare it to a sinusoidal
modulating signal one which deviates ±19kHz. The result, expressed in dB, must be lower or equal
to zero to comply with the rule.

RDS/RBDS

One of our core competencies lies in the RDS/RBDS. The RDS/RBDS page is very

comprehensive, with a display of the RadioText (RTA and RTB), basic RDS/RBDS elds and a

table of all decoded RDS/RBDS groups with a percentage measurement based on the overall RDS/
RBDS data stream or group count. A very useful graph on this display is the rolling RDS/RBDS
bit error rate (BER) display.

Total groups received indicator – all received groups are systematized into a table, representing
the percentage/quantity of the groups in the received RDS/RBDS signal. The user selects how the
“Total groups received” data should be displayed: as Percents [%] or [Count], by selecting the
corresponding button.

NOTE: The bit error rate or bit error ratio (BER) is the number of bit errors divided by the

total number of transferred bits during a studied time interval. Result closer or equal to 0 indicates
that no bit errors are detected and vice versa result closer or equal to 1 indicates that the received
transferred bits are only errors.

Basic RDS

PI/CALL (Program Identication) – The PI code is your station’s ‘digital address’. It is a

hexadecimal code that is assigned by an appropriate broadcasting authority in most countries, but
in the United States the PI code is numerically calculated from the station’s call sign. We have
provided a calculator utility within the DB4402-V2. An in-depth discussion of the mathematical
calculation is given in RDS/RBDS Standard.;

PS (Program Service Name) – This is the station’s “street name” that will appear on the receiver
faceplate display. The PS can be up to eight characters in length (including spaces) and can be as
simple as the station’s call letters: KWOW or KWOW FM, or a slogan: NEWSTALK or LIVE 95.

PTY (Program Type) – The PTY data ag identies the station format from a pre-dened

categories. Many RDS receivers are able to seek the listener’s preferred format automatically.

This means that a car radio can switch from a fading station to a stronger one that carries the
same variety of music, though not the very same program, as provided by AF switching. The PTY
function of RDS helps a broadcaster catch ‘transient audience’ share. The PTY code is not meant
to change from song to song or to accommodate a top-of-the-hour newscast, however.

MS (Music/Speech Switch) – This ag simply indicates whether music or speech is the primary

broadcast programming.

RT (Radio Text) – This is a 64-character block of plain text that the listener can select for
visual display on the faceplate of the radio by pressing an INFO button on the receiver. This
function is not available on many automobile radios for safety reasons, which has precipitated the

frowned-upon practice of scrolling the PS eld instead. The Radio Text can announce song titles

and performers, run special promotions or contests, or broadcast sponsors’ messages.

DI (Decoder Information) – This is one of several ‘ags’ that convey yes/no or other very
basic data. This particular ag tells the receiver whether the broadcast is monaural, or is being

transmitted in any of several methods of stereo or binaural broadcasting.

TP (Trafc Program Identication) – The TP ag identies the station as one that routinely
broadcasts trafc bulletins for motorists as part of its normal, everyday programming. When the
TP ag is displayed on the receiver faceplate, the radio is searching for trafc announcements. The

radio keeps track of TP stations offering this service to speed up the search-and-switch process.

TA (Trafc Announcement) – This is a temporary ag added to the RDS data stream only
when a trafc bulletin is being aired. Some RDS car radios can be set to search for trafc bulletins

among various TP stations while tuned to a listener’s preferred program, or even while playing

a tape or CD. As soon as any TP station broadcasts a trafc bulletin, the receiver temporarily
switches-over to receive it. When the bulletin is nished, the receiver switches back to the original

program, tape or CD.

List of Alternative Frequencies – A network broadcaster, or one with low-power rebroadcast

transmitters (translators) to ll holes in his coverage area, can include a list of all frequencies where

the identical program can be heard simultaneously. The RDS receiver (particularly the upscale car
radio) constantly searches for the best signal that carries the very same program. When a better
signal is found, the radio re-tunes with no noticeable interruption. The principal utility of this RDS
function is with European radio networks and US stations with ‘translators.’

PIN - Program Item Number: The code enables the designed to use this feature receivers
and recorders to respond to the preselected by the user program item(s).This feature is used via
scheduled program time, to which in order to avoid ambiguity is added the day of the month.

Date and Time – Decoded CT information.

Radio Text +

RadioText Plus is “semantic analogue radio”. It allows the RDS feature RadioText (RT) to be
read by the FM RDS receiving terminals. Based on the RDS RT messages, RT+ is completely
backwards compatible with RT. The usage of RT+ allows the listener/user to derive additional

benets from the RDS Radio Text service. It enables FM RDS receivers to “read” Radio Text
(to recognize designated objects and make them manageable) by user’s direct access to specic

elements of the Radio Text messages. For example, that element could be programme associated
metadata like Title and Artist of the currently playing song or a news headlines. This provides the
listener with an “mp3-player feeling” while listening to analogue FM radio. The elements can also
carry additional service messages or information about the Radio Station such as the telephone
number or the web address of the Radio Station’s hotline. These objects, or more accurately RT+

information elements carried in the RDS RadioText (RT) messages, are identied by their location

within the RT messages and by the class code of their content type. Once an information element
is received and understood, a receiver is able to, for example, store the different RT+ information

elements and the listener may then select and request a specic content type from the radio’s

memory at an instant in time that suits the listener’s needs. Thus the listener is no longer forced
to watch the RT information passing (scrolling) by. Moreover, RT+ offers selected RT message
elements to car drivers on a static display, without risk of distracting the attention of the driver.
Furthermore, RT+ is well suited for mobile phones with built-in FM receivers: telephone numbers
can be directly used to initiate calls, and web addresses can be used to start browsing the web
content offered by the radio programme provider. Last but not least, RT+ is also used for satellite
radio broadcasting via DVB-S. It may be adopted by DRM and DAB in the future, too.

RDS/RBDS

E-mail: of[e-mail] ,Web: www.devabroadcast.com

One of our core competencies lies in the RDS/RBDS. The RDS/RBDS page is very

comprehensive, with a display of the RadioText (RTA and RTB), basic RDS/RBDS elds and a

table of all decoded RDS/RBDS groups with a percentage measurement based on the overall RDS/
RBDS data stream or group count. A very useful graph on this display is the rolling RDS/RBDS
bit error rate (BER) display.

Total groups received indicator – all received groups are systematized into a table, representing
the percentage/quantity of the groups in the received RDS/RBDS signal. The user selects how the
“Total groups received” data should be displayed: as Percents [%] or [Count], by selecting the
corresponding button.

NOTE: The bit error rate or bit error ratio (BER) is the number of bit errors divided by the

total number of transferred bits during a studied time interval. Result closer or equal to 0 indicates
that no bit errors are detected and vice versa result closer or equal to 1 indicates that the received
transferred bits are only errors.

Basic RDS

PI/CALL (Program Identication) – The PI code is your station’s ‘digital address’. It is a

hexadecimal code that is assigned by an appropriate broadcasting authority in most countries, but
in the United States the PI code is numerically calculated from the station’s call sign. We have
provided a calculator utility within the DB4402-V2. An in-depth discussion of the mathematical
calculation is given in RDS/RBDS Standard.;

PS (Program Service Name) – This is the station’s “street name” that will appear on the receiver
faceplate display. The PS can be up to eight characters in length (including spaces) and can be as
simple as the station’s call letters: KWOW or KWOW FM, or a slogan: NEWSTALK or LIVE 95.

PTY (Program Type) – The PTY data ag identies the station format from a pre-dened

categories. Many RDS receivers are able to seek the listener’s preferred format automatically.

This means that a car radio can switch from a fading station to a stronger one that carries the
same variety of music, though not the very same program, as provided by AF switching. The PTY
function of RDS helps a broadcaster catch ‘transient audience’ share. The PTY code is not meant
to change from song to song or to accommodate a top-of-the-hour newscast, however.

MS (Music/Speech Switch) – This ag simply indicates whether music or speech is the primary

broadcast programming.

RT (Radio Text) – This is a 64-character block of plain text that the listener can select for
visual display on the faceplate of the radio by pressing an INFO button on the receiver. This
function is not available on many automobile radios for safety reasons, which has precipitated the

frowned-upon practice of scrolling the PS eld instead. The Radio Text can announce song titles

and performers, run special promotions or contests, or broadcast sponsors’ messages.

DI (Decoder Information) – This is one of several ‘ags’ that convey yes/no or other very
basic data. This particular ag tells the receiver whether the broadcast is monaural, or is being

transmitted in any of several methods of stereo or binaural broadcasting.

TP (Trafc Program Identication) – The TP ag identies the station as one that routinely
broadcasts trafc bulletins for motorists as part of its normal, everyday programming. When the
TP ag is displayed on the receiver faceplate, the radio is searching for trafc announcements. The

radio keeps track of TP stations offering this service to speed up the search-and-switch process.

TA (Trafc Announcement) – This is a temporary ag added to the RDS data stream only
when a trafc bulletin is being aired. Some RDS car radios can be set to search for trafc bulletins

among various TP stations while tuned to a listener’s preferred program, or even while playing

a tape or CD. As soon as any TP station broadcasts a trafc bulletin, the receiver temporarily
switches-over to receive it. When the bulletin is nished, the receiver switches back to the original

program, tape or CD.

List of Alternative Frequencies – A network broadcaster, or one with low-power rebroadcast

transmitters (translators) to ll holes in his coverage area, can include a list of all frequencies where

the identical program can be heard simultaneously. The RDS receiver (particularly the upscale car
radio) constantly searches for the best signal that carries the very same program. When a better
signal is found, the radio re-tunes with no noticeable interruption. The principal utility of this RDS
function is with European radio networks and US stations with ‘translators.’

PIN - Program Item Number: The code enables the designed to use this feature receivers
and recorders to respond to the preselected by the user program item(s).This feature is used via
scheduled program time, to which in order to avoid ambiguity is added the day of the month.

Date and Time – Decoded CT information.

Radio Text +

RadioText Plus is “semantic analogue radio”. It allows the RDS feature RadioText (RT) to be
read by the FM RDS receiving terminals. Based on the RDS RT messages, RT+ is completely
backwards compatible with RT. The usage of RT+ allows the listener/user to derive additional

benets from the RDS Radio Text service. It enables FM RDS receivers to “read” Radio Text
(to recognize designated objects and make them manageable) by user’s direct access to specic

elements of the Radio Text messages. For example, that element could be programme associated
metadata like Title and Artist of the currently playing song or a news headlines. This provides the
listener with an “mp3-player feeling” while listening to analogue FM radio. The elements can also
carry additional service messages or information about the Radio Station such as the telephone
number or the web address of the Radio Station’s hotline. These objects, or more accurately RT+

information elements carried in the RDS RadioText (RT) messages, are identied by their location

within the RT messages and by the class code of their content type. Once an information element
is received and understood, a receiver is able to, for example, store the different RT+ information

elements and the listener may then select and request a specic content type from the radio’s

memory at an instant in time that suits the listener’s needs. Thus the listener is no longer forced
to watch the RT information passing (scrolling) by. Moreover, RT+ offers selected RT message
elements to car drivers on a static display, without risk of distracting the attention of the driver.
Furthermore, RT+ is well suited for mobile phones with built-in FM receivers: telephone numbers
can be directly used to initiate calls, and web addresses can be used to start browsing the web
content offered by the radio programme provider. Last but not least, RT+ is also used for satellite
radio broadcasting via DVB-S. It may be adopted by DRM and DAB in the future, too.

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 parameters monitored. In case that a parameter
is beyond limits, the device will initiate the sending of an alarm or warning notication via the

selected communication path. All the alarm and warning 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 ‘trigger
time’, the device would not trigger an alarm or warning.

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.

APPENDIX B

GSM MODEM OPTION - FEATURES AND USAGE

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

- DB44 – Compact FM Radio Monitoring Receiver

- DB45 – DSP-Based FM Radio Receiver and Modulation Analyzer

- DB4004 – DSP-based FM Radio Monitoring Receiver

- DB7000 – FM Radio Re-Broadcast Receiver with Built-in IP Audio & MP3 Backup Players

- DB7007 – Advanced FM Radio Re-Broadcast Receiver with IP Audio & MP3 Backup Players

- DB4402-V2 – High-Performance Dual FM Monitoring Receiver & Radio Streamer

The DEVA FM 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 Unit.

The GSM modem model is directly PIN to PIN compatible with the DEVA Unit 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 DEVA Unit. 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

Upon powering on, the modem should start working with its factory settings. To see these
settings type the command “AT&V”. The modem will respond with the factory default settings:

Q:0 V:1 S0:000 S2:043 S3:013 S4:010 S5:008

+CR:0 +CRC:0 +CMEE:0 +CBST:0,0,1

+SPEAKER:1 +ECHO:0 &C:0 &D:2 %C:0

+IPR:115200 +ICF:3,4 +IFC:2,2

ATTENTION: If the displayed parameters differ from one listed above, we recommend you

to return the modem to its factory defaults. In order for this to happen, the command “AT&F1”
should be typed.

NOTE: For further information on the AT commands, please refer to the GSM Modem complete

user manual.

Once the modem is returned to its factory defaults, you can proceed with following commands:

COMMAND DESCRIPTION NOTE

ATE0 This command will turn

Echo Off
AT+ICF=3,4 8n1, no parity
AT+IFC=0,0 no ow control
AT+IPR=9600 set com speed Change terminal speed to 9600 bps (if needed)
AT&W save conguration After this command turn power Off and On
AT&V display new conguration

NOTE: After every command, the modem should respond with “OK”.

Once all changes/modications are applied, the modem should respond with the following

adjustments:

Q:0 V:1 S0:000 S2:043 S3:013 S4:010 S5:008
+CR:0 +CRC:0 +CMEE:0 +CBST:0,0,1
+SPEAKER:1 +ECHO:0 &C:1 &D:2 %C:0

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.

3. Example of FTP Client (FileZilla) Settings

In some cases, FileZilla’s “Quick connect” feature is not able to connect with the DEVA unit.

That is why we recommend the device to be assigned in the program manually.

Enter the FTP Client and go to: File > Site manager > New Site. A dialog box requiring

obligatory information about the device will appear. Fill in the needed information and press “OK”.

Select “Transfer Settings” sub-menu and apply the settings as shown below:
