Getting Started

DB2003 has three logical Telemetry Ports – Telemetry Port 1, Telemetry Port 2 and Telemetry
Port 3. Each Telemetry Port can connect to the monitored device via one of several available physical
interfaces.

INTERFACES

DB2003 has two connectors to the monitored device - COM1 and COM2. The COM1 connector

2

supports RS232 interface only. The COM2 connector is multi-functional, supporting I

MONITORED DEVICES

DB2003 can be used with the following RVR Elettronica devices:

• Transmitter/Exciter series: PTX_LCD, PTX_DDS, PTX_LCD_DSP, TEX_LCD and Blues;

• Power Ampliers: PJ, Plug-in KPS-CA and Barracuda;

• Change-over Units.

The monitored device must be connected through a cable to the DB2003, with the relevant

Telemetry Port set up as specied in the “Telemetry Port Settings” on page 24.

You will nd details on the cables for connecting the DB2003 to the monitored device in

“APPENDIX A” on page 49.

SETTING SCENARIO

DB2003 has several communication interfaces: 2х RS232, RS485 half duplex and I2C.

DB2003 has three Telemetry Ports. Each Telemetry Port can use any of the available interfaces to
connect to its corresponding monitored device. Multiple scenarios are possible, with the monitored
devices not exceeding 3 (the number of Telemetry Ports).

Some monitored devices can be connected via RS232 and/or I2C (PTX_LCD). Plug-in KPS-CA
can be connected via RS485 or RS232, but the preferred interface is RS485, so RS232 can be available
to service the transmitter.

In accordance with their installation, the client must make the necessary cables. Details on Cables
and connectors can be found in “APPENDIX A” on page 49.

DB2003 is able to send alarm notications via SMS using a GSM modem, which is purchased

additionally. The Modem is connected to communication port “COM1” and upon activating it, that
port cannot be used to connect to a monitored device.

Depending on the selected operation mode, the DB2003 can be used for:

• passive monitoring of the monitored device, without affecting it;

• remote control of the monitored device through commands sent by an operator;

• automatic control of the monitored device by a set schedule – change of power.

DAYPARTS

DB2003 allows users to set up a weekly schedule to manage the power of the monitored device.
Not all monitored device series can be managed. This functionality is available for PTX_LCD, PTX_
LCDDSP, PTX_DDS ,TEX_LCD, Blues, Plug-in KPS-CA and Barracuda.

Users can set two levels – Low Power and Full Power. When there is an active Daypart, a command
is sent to manage the power level to Low Power. When there is no active Daypart, a command is sent
to manage the power level to Full Power.

Further details on the setup and use of Dayparts are available in “Dayparting” on page 27.

ALARMS

DB2003 allows you to set a value threshold for some of the monitored signals. If a value stays

beyond that threshold for a certain amount of time, an alarm event notication is sent.

The notication can be made in one way or in a combination of ways: E-mail, SNMP trap, SMS

or GPO activation.

For some signals, it is possible to monitor high and low threshold, e.g. Forward Power and

Temperature. For other signals, such as Reected Power, only the upper threshold can be monitored.
A notication is sent both when the signal goes beyond the threshold (alarm activation), and when

normal values are restored (idle).

An alarm notication is also sent when there is an event such as loss of connection with the
monitored device. No threshold or time delay is set for this alarm type. For some events, a notication

is not necessary for a signal’s return to normal status, e.g. in the case of power change.

Depending on the monitored device series, the number and type of alarms available will also
change. Logging on as admin allows you to select which ones to activate and at what thresholds.

Further details on the setup and use of Alarms are available in “Alarms” on page 28.

Device Settings

This chapter lists the settings inuencing the operation of the DB2003 but having no direct
inuence on the monitored device, as well as its selection and connection.

There are two levels of login rights to the DB2003: as admin or as user. These are default
usernames, which can be changed. Each of them has its own password for access. Admin has full
access to the device and can remotely manage the monitored devices. The session is maximum 10
minutes long (subject to setup) and can be renewed. The admin session can be interrupted by an
SNMP user for a set operation.

User has limited rights. It can monitor but can not edit. It has no access to settings and cannot

change the operation mode of the DB2003 or inuence monitored devices. Its session can be set to

no time limits but can be interrupted by admin or by an SNMP user for a set operation.

HARDWARE FACTORY DEFAULT

It is recommended that the device should have no cables and power supply connected. Press and
hold the RESET button (between COM1 and COM2). Then feed power to the device, with the button
held pressed for at least 5 seconds, until all LED’s on the lower row start blinking simultaneously.
Release the button and wait for a few seconds until the process is completed and the PWR LED is on.

This procedure restores all settings to their factory defaults, including the device’s IP address.
DHCP is on. Logs are not deleted.

GENERAL SETTINGS AND DEVICE STATUS

Alias – helps the user recognize the device.

Timezone – setting the correct value will allow automatic setting of DB2003’s time in accordance

with its location.

Admin Name and Admin Password – Admin access credentials. Default values are admin and
pass.

User Name and User Password – access credentials with user rights. Default values are user and
pass.

The Device Status section provides information about the current status of the device – rmware

version, serial number, current device time, used and free internal storage space, GPO status.

NETWORK SETTINGS AND STATUS

This section contains information about IP Address and assignment type, DHCP enable/disable,
network mask, gateway, primary and secondary DNS, MAC address.

SNMP AGENT

The SNMP Agent section allows you to Enable/Disable agent, change agent and manager ports
and set manager address (SNMP trap receiver). The DB2003 uses SNMP version 2 – the Read/Write
community is similar to a password for read/write access. Use the agent ID to distinguish between
multiple agents in one trap receiver.

You can download the MIB le as well as test the entire route from end to end.

Tel: [phone], Fax: [phone]

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

To receive alarm event notications by email, you must specify the receiver’s address. You can set

one or two receiver addresses.

In order for the notications to be received, the DB2003 requires an email server to re-direct them.

There are two options here:

1. You can use the address of a server you are using;

2. You can use a server provided by DEVA for the purpose .

PLEASE NOTE that notications may be ltered as spam and may not reach the receiver.

HTTP SERVER AND FTP SERVER

When the HTTP server is disabled, access via WEB browser is no longer possible. However, users
can still have access via SNMP. It is possible to change the default port – when there are several
devices with the same external IP address.

Here, you can also set the duration of the admin session. When that time elapses, and the device
is not being actively used, the session is automatically terminated to allow access to user. It is
recommended that you log out.

When setting zero duration for the user session, it becomes unlimited. It may be interrupted upon
access request by admin or by an SNMP set operation.

SNTP CLIENT

It is recommended that this service should remain enabled, so the DB2003 can automatically set
its time. That ensures that the time in the system and port logs is accurate.

You can also specify another time server.

GSM MODEM

To receive an SMS as an alarm notication, you must connect a GSM Modem to the DB2003. The

modem has to have an active SIM card, with the PIN code protection disabled. Set the GSM Modem
to COM1 to enable communication. If there are no issues, Status must become Active, as illustrated
above.

In the right-hand section, set the phone numbers of up to 5 message receivers. Use the [Test]

button to make sure all of them receive the notications.

When selector “GSM Modem” is set “to COM1”, even if there is no connected modem,
communication port COM1 is not available and cannot be used to connect to the monitored device.

GENERAL-PURPOSE OUTPUTS

DB2003 has three general purpose outputs: GPO1, GPO2 and GPO3. They have identical
functionality and are hereinafter to be referred to as GPO’s. Each GPO is the TLV817 optocoupler
photo transistor collector (NPN transistor, Vce = 30V max, Ic = 20mA max). Each of the three
emitters is connected to common ground. It may be seen as a normally open contact. A Pinout is
shown in “COM2 Connector” on page 11.

You can set an appropriate alias for each GPO as a reminder of what it controls.

In accordance with its function, each GPO can be controlled by an alarm event, by ping watchdog
or manually. You can select whether an alarm event will cause opening or closing of the contact.

PLEASE NOTE that without a power supply, the GPO is normally open, which can be interpreted

as a false alarm.

With manual control or ping watchdog, you can select a stable status change or a change for a
certain amount of time (Pulse Duration).

In order for a GPO to be used as an alarm event output, the following three conditions must be

fullled:

1. The Alarm Output function must be selected;

2. In the Telemetry Port/Alarms setting, the Enabled option must be selected for GPO;

3. The GPO must be indicated in Notications/GPO. Further details on alarms are available in

“Alarms” on page 28.

In order for the GPO to be used as a ping watchdog output, you must select the relevant output

function and specify in the ping watchdog setting which GPO must be used.

For manual control of the GPO, select the relevant function. Set the required output status. You
can select a pulse type and start a pulse with the set duration. PLEASE NOTE that without a power
supply, the GPO is normally open, which can be interpreted as a false activation.

PING WATCHDOG

You must enter an address to which the DB2003 must send a ping at certain intervals. When the
set number of unsuccessful attempts is reached, the selected GPO is activated. A GPO is generally of
the pulse type and cuts the power supply to the controlled device, causing a reboot.

Startup Delay sets the time for the controlled device to reboot, during which no ping is sent.

With the [Test] button, users can check the routing to the specied address.

DEVICE MANAGEMENT

Reboot Device

[Reboot Device] causes the device (DB2003) to re-start. It does not change the settings or delete
the logs. If Dayparting has been activated for any Telemetry Port, a command will be sent to the
monitored device to determine the forward power in accordance with the current time.

Restore All Except IP

[Restore All Except IP] causes all settings to be restored to their default values. It does not affect
the IP address settings, so it is still possible to connect to the device. The Timezone setting is not
changed. Logs are not deleted.

No commands are sent to the monitored devices. All Telemetry Ports are disabled, selected models
and parameters for connecting to the monitored devices are canceled.

RECOMMENDATION: Prior to taking this action, make sure you have all the data required for

restoring the connection to the monitored devices – interface, speed, address, model, etc.

Storage Format

Storage Format is where you can format the internal storage. All logs are deleted. It does not affect
the settings regarding the connection with monitored devices. No additional commands are sent to
the monitored devices.

When “Warning Level” is Enabled and Used exceeds the set level, a message is shown:

The message disappears when “Warning Level” is Disabled or when the set level exceeds the
used one:

• Warning Level increases;

• Memory is freed by removing old les – use FTP client;

• [Format] – deletes ALL les – System and Port LOGs.

Firmware Update

Firmware Update installs an updated DB2003 rmware version. Unless there are explicit
instructions accompanying the rmware, it does not cause or require change in any of the settings.

It does not delete the logs. If Dayparting has been activated for any Telemetry Port, a command will
be sent to the monitored device to determine the forward power in accordance with the current time.

Notify Power Up

If you Enable the respective notication channel (Email, SMS, SNMP trap), you will receive a
notication once DB2003 boots up. For that to happen, settings for the notication channel must be

applied.

LOGS

DB2003 creates two types of logs – System Log and Port Logs. The System Log can be read via
the WEB interface.

Select the desired date, Month, Year and see the Log for the respective day. With “All”, you can
select for Day all the days of the Month; if a great deal of information has been stored, please allow
for a certain delay. To quickly switch back to today’s log, use the [Today] button.

Log can be sorted by column: Data/Time, Type or Message – in descending or ascending order.

There are lters to select only the required information – for a specic time, type of log, port or

certain events.

Recording data in the System Log cannot be disabled. The System Log does not record the values

of the signals read from the monitored devices. The les can also be accessed via FTP at “sys”.

To record data in the Port Logs, this must be allowed with the relevant Telemetry Port setting (see

“Telemetry Port Settings” on page 24). Users must set the required interval for recording the data read

from the monitored device. It is recommended that a short interval (in seconds) should be set at only
one port, for a limited time. Especially in the case of a monitored Plug-in, the size of Port Logs is
too large, which makes working with them more difcult. The Port Log data is extracted from the
DB2003 and visualized in the appropriate way through specialized software.

Telemetry Port Settings

The settings for each port are identical. This Guide is to designate each port with the phrase
Telemetry Port. The Dayparting function is not available for all monitored device series and may
therefore not be displayed on the settings screen. The number and type of alarm events is different
for each series and may differ from the ones described below.

GENERAL

In this group of settings, you have to specify the device the DB2003 is to monitor/control and how
to connect to it. Setting an Alias allows the user to recognize the different monitored devices. This is
where you enable/disable the port.

Select Model & Connect

The set interface must match the one which is physically connected. The address and speed of the
connection must correspond to the ones set in the monitored device. With the I
not taken into consideration.

With different interfaces, the address can be the same for several ports, but when the connection
is over I2C, different addresses must be set to differentiate between devices. If required, set another
address into the monitored device.

The models in the PTX_LCD, PTX_DDS, PTX_LCDDSP, TEX_LCD and Blues series have
different nominal forward power. If you select another model from the same series, which is different
from the one actually connected, the DB2003 will not be able to tell the difference. The power in
W when setting alarm and dayparts thresholds will be calculated against the nominal power of the
set model. For alarms, power is compared in W, while for Target Power command values are in
percent. That will lead to a difference between the transmitter’s power and the power expected by
the DB2003.

The models from the Plug-in KPS-CA and Barracuda series differ by the number of RF Units.
When a model is set, which is different from the one actually connected, the DB2003 will not display
the data from all RF units or will try to request and display data from non-existent RF units.

It is highly recommended that you set a model precisely as the one connected.

Dangerous Parameters

The change in some parameters is dangerous, e.g. the change in the transmitter’s frequency. The
DB2003 has a designated mechanism to limit such actions, therefore the default Edit Dangerous
Parameters value is Disable. In this case, the dangerous parameters are not available for telecontrol.
When the selected value is Enable, the dangerous parameters are displayed and can be edited. They
are marked by a warning sign.

When you have selected the value “For a limited time”, you see a ticker counting seconds down

- this is the time in which the new value must be entered and saved. This mechanism presupposes
awareness of whether the operator’s actions are necessary.

With this setting, you can disable or enable the recording of a log for the respective port, and
choose the required logger interval for recording data from the monitored device. The port logs data
is extracted from the DB2003 and visualized in an appropriate way via specialized software. In order
for the software to work, the FTP server of the DB2003 must be enabled.

It is recommended that a short interval (in seconds) should be set at only one port, for a limited
time. Especially in the case of a monitored Plug-in, the size of port logs is too large, which makes

working with them more difcult.

DAYPARTING

DB2003 allows users to create a weekly schedule to control the power of the monitored device.
Not all series of monitored devices can be managed in this way. The functionality is available for
PTX_LCD, PTX_DDS, PTX_LCDDSP, TEX_LCD, Blues, Plug-in KPS-CA and Barracuda.

Two levels are set, called Low Power and Full Power. When there is an active Daypart, a command
is sent to control the power to Low Power. When there is no active Daypart, a command is sent to
control the power to Full Power.

There are 8 Dayparts selectors with identical parameters. It is possible to set overlapping values;

it is sufcient for one Daypart to be active to set Low Power.

To set values for Low Power and Full Power, the relevant value is in percent. The value in W
is calculated against the nominal power for the selected monitored device model. The Plug-in and
Barracuda series allow you to set Target Power up to 105%, while PTX, TEX and Blues – up to
100%.

When Dayparts are enabled, the setting of Forward Power is controlled by the DB2003 and the
relevant parameters are not available for telecontrol – Target Power for PTX, TEX and Blues, and
Selected Power for Plug-in: Nominal/Lower and the Nominal and Lower values. For the PTX, TEX
and Blues models, the DB2003 monitors and controls the Target Power parameter. For the Plug-in
models, respectively Nominal or Lower Power is selected via Selected Power, while at the same time
the values of the two levels must match the ones set in Dayparts. The DB2003 sends commands to
control the power but does not change the On-Air status.

For each Daypart, users must set the day of the week when it must be active. Selecting Never

disables the respective Daypart. Selecting Every Day ensures Daypart is active for the specied time

frame, regardless of the current day.

The active time frame is dened by its Start time and Duration.

ALARMS

DB2003 allows you to set a threshold for the values of some of the monitored signals. When the

threshold is passed and this continues for a certain amount of time, an alarm event notication is sent.

The notication can be made in one way or in a combination of ways: E-mail, SNMP trap, SMS or
GPO activation. You must Enable/Disable the respective notication method for all Telemetry Port

alarms. That way, you can disable all alarms for this particular Telemetry Port. For each alarm, the

notication method is selected individually.

Alarms List

For some signals, both high and low threshold are monitored (Forward Power, Temperature,

Modulation), while for others - only high threshold is (Reected and Unbalanced Power). A
notication is sent whenever the value passes the threshold (alarm activation) and upon its return to

normal status (Idle).

An alarm notication is also sent in the case of an event such as loss of connection with the

monitored device. For this type of alarm, no threshold or delay is set. For some events, it is not

necessary to send a notication for the return to normal values – for example that is the case with

power change.

To set up an email notication, the following must be fullled:

• the [E-mail] button in the Notications for the alarm must be enabled;

• e-mail notication must be enabled for the entire Telemetry Port;

• a receiver must be entered in Settings> Device> E-mail. (see “E-mail” on page 17)

To set up an SNMP trap notication, the following must be fullled:

• the [SNMP] button in the Notications for the alarm must be enabled;

• SNMP trap notication must be enabled for the entire Telemetry Port;

• a receiver must be entered in Settings> Device> SNMP Agent> Manager IP. (see “SNMP

To set up a GPO notication, the following must be fullled:

• the output must be selected from the [GPO] button in Notications for the alarm;

• GPO notication must be enabled for the entire Telemetry Port;

• the Alarm Output function must be set for the respective output in Settings> Device> GPO.

(see “General-Purpose Outputs” on page 19)

The alarm thresholds are used to highlight signal values. If the alarm is not enabled, the threshold
pass is still registered with the highlighting of the signal.

The alarm can be enabled without any Notications being selected. In this case, the main screen will
show the abnormal signal in the alarm indicators eld but will not send any activation notications.

When both the alarm and the Notications are enabled, upon activation of the alarm a notication

The values of the main signals get highlighted in red when the set alarm thresholds are passed.
This happens even when the alarm is not Enabled – as illustrated by Unbalanced Power in the upper
section of the image. The value is in red but there is no Unbalanced Power alarm indicator on the

These are the Alarm Log contents of the monitored device. It is not connected to the port or system
logs recorded by the DB2003.

Plug-in records in its Alarm Log in accordance with its conguration (more on which will be

discussed further on). These logs are not affected by the DB2003 settings. They are just displayed
here. The entire log can be deleted with a command by a DB2003 operator (see “Telecontrol” on

page 38).

Next comes the Release tab, displaying the Transmitter’s units, identication serial numbers of
the entire transmitter and the separate units, as well as the rmware version in use for each unit. (The

action is undertaken; the event is only recorded in the log. With Retry, the set number of attempts is
undertaken to return the signal to normal value. If the attempts are unsuccessful, the status switches
to Fault and the unit switches off. When the value is Fault, the unit immediately switches off.

These are the signal limits – passing them creates Alarm log entries. These values are set by the
manufacturer during production of the transmitter. Here, they are displayed in order to inform users
of the types of situations that would lead to Alarm log entries.

This table shows the signal values for all RF Units. As with Combiner, it displays the actions
which would be undertaken by the respective RF Unit if the signal limit is passed.

For the signals which do not have a DB2003 alarm, conguration thresholds are used to highlight

the signal value. This applies to all RF Units signals.

In the conguration table of the RF Units, the high threshold for MOS current is 36А, and the

action is Retry 8. The Alarm Log image shows the attempts to restore the respective parameter to
normal. Failure has led to a Fault status.

The power control parameters are under the control of Dayparts and cannot be managed remotely by
an operator – the Nominal/Lower Power button and the values for the two thresholds.

The [Change Exciter] button causes an exciter changeover. For that action to be successful, the
exciter changeover mode must be “Manual” (that is not the case in the image above). Pressing this
button is equivalent to performing the same action through the Exciters menu on the transmitter’s
front panel.

The [Alarm Reset] button cancels the Fault status. It is equivalent to pressing the same button on
the transmitter’s front panel.

The [Clear Alarm Log] button deletes the transmitter’s log. WARNING: This action is irreversible
– once deleted, the Alarm log data cannot be restored.

The [Sync Time/Date] button synchronizes the transmitter’s time (used in the Alarm log) with that
of the DB2003. The DB2003 cannot be aware of the Plug-in time, so it is impossible to know what
the correction is when this action is performed.

The difference between Plug-in time and DB2003 time can be inferred from the System Log data
of the DB2003 when “Alarm Log” is Enabled:

The time shown in the Date/Time column is from the DB2003, while the time in the Message
column is from the Plug-in.

The time synchronization command for Plug-in is rounded off in whole minutes, without seconds.
This means that when the button is pressed, the DB2003 receives a synchronization request and in
fact sends a command to the Plug-in shortly before the start of a new minute.

SNMP

SNMP is a convenient way of integrating the DB2003 into systems for automatic monitoring and
control of multiple transmitters. It can be used with the help of a free Android application to check
on the status or apply additional settings to the transmitter through a smartphone when the time or
location is inconvenient.

This Guide uses screenshoots from iReasoning MIB Browser Personal Edition – a free-of-charge

version of an excellent software tool of sufcient functionality.

SNMP AGENT

For SNMP to work, SNMP Agent must be Enabled and the respective ports must be routed. Go
to Settings> Device> SNMP Agent to set as Manager IP the IP address of the computer which is
running the trap receiver.

Set an appropriate value for Agent ID in order to be able to identify the sender in the case of
several DB2003’s sending traps to the same receiver.

With the [Test Trap] button, you can check the negotiability of the entire route.

DB2003 uses SNMP v.2, with Read/Write Community serving as a password for granting reading
and writing access respectively. Default values are shown. It is recommended those should be
changed for security reasons.

In the “product” folder are OID’s which allow users to identify instances of DB2003 – each

manufactured device can be unambiguously identied by ‘sernum’ (it’s serial number).

The “settings” folder corresponds to Settings on the web page: under “device” are settings related
to the DB2003 itself, while the“telemetry Port” folders contain settings related to the monitored
devices connected on each port – General, Dayparts and Alarms.

Under the “telemetry” folder are OID for readings – this is information read from the monitored
device.

There are folders for every Series containing a Readings Table. The table has three columns – one
for each telemetry port.

For example, Telemetry port 2 monitors a PTX. The “port2” column shows readings from the
PTX. The other columns show “bad PID” – there are no PTX’s connected to these telemetry ports.

The table index starts from a zero value. The index for port1 is therefore 0, the one for port2 is 1,
and the one for port3 is 2.

texPortIdx, etc., each with values 0, 1 and 2 for the respective port.

For access to a separate signal, add the port index to the OID. For example, OID ptxFreq has the
following value:.1.3.6.1.4.1.35833.2003.3.1.1.1.4

For access to the signal from port1, add .0 to the OID:
.1.3.6.1.4.1.35833.2003.3.1.1.1.4.0
For access to the signal from port2, add .1 to the OID:
.1.3.6.1.4.1.35833.2003.3.1.1.1.4.1
For access to the signal from port3, add .2 to the OID:
.1.3.6.1.4.1.35833.2003.3.1.1.1.4.2

The “kps” folder contains several tables. They allow users to work with transmitters from the
Plug-in and Barracuda series. The kpsTable contains information on Control Unit, Power Supply,
Combiner, etc., without RF Units. It is indexed by Telemetry Port – 0, 1 and 2. The parameters for
telecontrol of the transmitter are here.

There are three more tables here. These are for RF Units: tm1kpsRFUnitsTable,
tm2kpsRFUnitsTable and tm3kpsRFUnitsTable. Select the appropriate one in accordance with the
Telemetry Port where the transmitter is connected. These tables are indexed by RF Unit. The number
of columns is determined by the number of RF Units of the selected model. Their content is similar
to that of the WEB interface in the RF Units\All RF Units sub-tab.

The remaining three tables in the “kps” folder – tm1kpsAlarmLogTable, tm2kpsAlarmLogTable
and tm3kpsAlarmLogTable, allow users to read the transmitter’s Alarm Log. Select the appropriate
one in accordance with the Telemetry Port. These tables are indexed by the number of log entries.
There may also be no entries. The kpsTable provides a kpsALogAlter ag, indicating a new entry.
This table also provides kpsALogLines (number of log entries) but when the maximum length of
the log is reached, this value is saturated. The image above shows the Alarm Log of a transmitter at
Telemetry Port 1 – the index is arranged by rows for clarity. This is the same content as that shown
above from the WEB interface’s Alarm Log tab.

Some of the signals have read-only Access. These are the values read from the monitored device
or the DB2003. In the MIB Browser read-only OID’s are marked with a green leaf. Other OID’s have
read-write Access. In the MIB Browser they are marked with a pen.

By entering an appropriate value, you can perform telecontrol of the transmitter or a DB2003
setting. The same parameters are available to edit here as the ones available for telecontrol through
the WEB interface.

By completing an SNMP set operation, a session is created in the DB2003. If another session has
been running at the same time by admin or user, it is terminated. The duration of the SNMP session
is selected in the SNMP Agent settings – Session Timeout. With a new recording operation, the
duration of the session is renewed. With SNMP reading, no new session is created and it not affect
the access of other users.

APPENDIX A

CABLES FOR CONNECTING TO THE MONITORED DEVICE

Cables must be shielded with a metal braid. The screen is soldered to the connectors’ casing. The
conductors must have be at least 0,22 sq. mm (23 SWG) across. Install the DB2003 close to the
monitored device and make sure the cables are not unnecessarily long.

COM1 CONNECTOR

The COM1 Connector services only one RS232 interface of the point-to-point variety. The cable
has one connector on each end – Male and Female. The connections are direct – Pin 2 to Pin 2, Pin 3
to Pin 3, Pin 5 to Pin 5 and Screen to Casing.

DB2003 COM1 to RS232 on Monitored Device

COM2 CONNECTOR

The COM2 Connector services three interfaces and GPO. At the most, four cables will come out
of the connector:

• Cable 1 to RS232 connector on monitored device;

• Cable 2 to RS485 connector on Plug-in (only Plug-in series models use RS485);

• Cable 3 is for I2C bus;

• Cable 4 is for GPO, if used.

The gures below represent diagrams of the separate cables. When making your cable, please
keep in mind that in all gures, COM2 could designate the same connector. At the most, the four

cables will use four connections to the common ground. Only three pins are available, one of which
will have to be shared by two cables.

APPENDIX B

CONNECTION INTERFACES USED WITH EACH SERIES

PTX_LCD

Devices from the PTX_LCD series offer two interfaces to connect to DB2003 – I
RS232. The REMOTE connector, type DB15 must be used for an I2C connection. Use “Cable 3” (see

2

“APPENDIX A” on page 49). If you connect multiple devices on the I

C bus, each device must have
a unique address. In the device screen menu, under the “General Set” page, the parameter is named
“UART Adr.”. The same value is used for the I

2

C bus address. In the DB2003, it is designated “Bus

Address” and is valid for all interfaces.

The RS232 connection can be made in two ways. On the PTX_LCD side, you can use the RS232
connector, type DB9. On the DB2003 side, you can use the COM1 connector and a straight cable, as
described in “APPENDIX A” - “COM1 Connector”. The second way is to use the COM2 connector
and “Cable 1”. When 2 devices are connected via RS232 (on COM1 and COM2), they can use the
same address value. It is important to set in both DB2003 and PTX_LCD the same values for Bus
Address and for Bus Speed.

2

C bus and

PTX_DDS and PTX_LCDDSP

Devices from this series use only an RS232 connection and it can be made in two ways. On the
PTX_DDS/PTX_LCDDSP side, use the RS232 connector, type DB9. On the DB2003 side, you can
use the COM1 connector and a straight cable, as described in “APPENDIX A” - “COM1 Connector”.
The second way is to use DB2003 connector COM2 and “Cable 1”. When 2 devices are connected
via RS232 (on COM1 and COM2), they can use the same address value. It is important to set in both
DB2003 and PTX_DDS/PTX_LCDDSP the same values for Bus Address and for Bus Speed.

Devices from the PTX_DDS and PTX_LCDDSP series have a REMOTE connector but it cannot
be used with the DB2003.

TEX_LCD and Blues

Devices from the TEX_LCD and Blues series use only an I

2

C bus connection, using the REMOTE
connector, usually type DB15. Use “Cable 3”. If you connect multiple devises on the I2C bus, each
device must have an unique address.

Devices from the TEX_LCD and Blues series have an RS232 connector but it cannot be used with

the DB2003.

PJ Ampliers

Ampliers from the PJ series use only an I

2

C connection. Usually, the connector is of the DB9
type and is designated ‘I2C BUS’. Use “Cable 3” from “APPENDIX A”. If you connect multiple
devices on the I2C bus, each device must have an unique address.

PJ ampliers have an RS232 connector but it cannot be used with the DB2003.

Plug-In series

Ampliers from the Plug-in series offer RS485 and RS232 connectivity. For the RS485 connection,

use “Cable 2”. The Plug-in connector is positioned on the rear panel of the Control Unit, type DB9
female, designated ‘RS485’.

On the front panel of the Control unit, there is a connector designated RS232. The Plug-in is
accessible from this connector, but this is not recommended. Leave this connector available to
service the transmitter. These two connectors share the same UART. When RS232 is used, the other
connector (RS485) is disabled internally. The DB2003 considers this as Link Loss and if the alarm is

enabled, notications are sent.

APPENDIX C

CONNECTION SCENARIOS

The following pages illustrate examples of installations. The gures show the necessary cables as

well as their corresponding connectors. Only the connections to DB2003 are described. To simplify

the gures, the remaining connections between the devices, such as power, audio and RF, have been

omitted.

The GSM Modem shown in the gures is optional. If it is not present in the gure, this means that

COM1 is in use and a Modem can therefore not be used.
