1. INTRODUCTION

Transmitter LX20B is a modern, microprocessor device for data transmission

in real time, with the transmission in the GSM. Connection with the monitoring
station, allowing you to transfer data from the control panel via the Contact ID
(DTMF) or SIA (FSK). There are available channels of transmission: GPRS / UMTS /
HSPA (3G) and SMS.

LX20B transmitter provides the highest security of data transmission through up
to transmission channels: / GPRS / UMTS / /HSPA (3G) / SMS. The primary purpose
is to use the device as a security systems transmission module. In addition, in the
LX20B-5D model there is possible to use two Nano SIM cards (two slots on the
PCB), which increases the reliability of the device for example in case of network
failure.

LX20B transmitter works with all most popular alarm systems. The addition of a
packet data transmission (GPRS / UMTS / HSPA), can reduce the cost of the alarm
systems. This device provides an opportunity to send text messages to private
mobile phones.

An advanced encoding methods like a 256 bytes encoding key and AES
(Advanced Encryption Standard) provides for security of data transmission. As a
result reception of this transmission is possible with OSM.Server monitoring receiver
system.
Furthermore there is possibility to transmit not coded messages that are to be
comprehensible by reception solutions and also by GPRS Server software.

Programming of receiver is possible:

o Locally on computer and with recommended “GPRS transmitter

configurator” software

o Remotely – via GPRS connection

– via SMS commands
– via transmission on CSD canal

LX20B – Manual Page 14 / 67

4. QUICK START PROCEDURE

NOTE:
Do not insert SIM card before the first programming of transmitter as it
may block the card if PIN code is required for the card.

This chapter is purposed for users that possess experience regarding GPRS
/ UMTS / HSPA (3G) data transmission systems and who work with
OSM.Server receiver for monitoring system. Other users shall skip this
chapter and go to chapter 5 of this Manual.

As many users possess protected facilities spread at vast locations, local
programming of transmitter is not always available (with PC computer and
programming cable).

Two phases comprise programming in this option:

a) sending to transmitter of main parameters (with SMS) that enable connection

to receiver (OSM.Server system).

b) full configuration of device with remote programming (GPRS transmitter

configurator and OSM.Server).

Quick start procedure:

a) insert into device SIM card with PIN code 1111 or disabled PIN code,
b) connect power supply for module,
c) send to SIM card number with SMS parameters related to connection of

device to receiver (OSM.Server)

d) waiting for moment, when device indicates connection to OSM.Server

Note: Connection to receiver is possible if the device was registered into it.

Registration procedure has been described in OSM.Server Operation Manual.

e) complete, remote programming with GPRS transmitter configurator.

SMS text message shall provide the following information:

<transmitter’s service code>█SERVER=<server address>█PORT=<server port>█

APN=<access point name>█UN=<user ID number>█

PW=<user password>

Where:

█: space (every parameter shall be separated with space – blank character)

<transmitter’s service code>: factory settings – 1111

<server address>: address of communication server purposed for collection of

transmitter signals e.g. 89.123.115.8. In case address is provided as domain e.g.
block.autostrada.com, SMS message shall include DNS1 parameter (address of main
DNS server)

<server port>: Number of port in server that receives messages from a device
<access point name>: defines access point name to GSM network.

If private network is used, SMS message shall provide the following parameters:
UN=<user ID number> and PW=<user password>.

LX20B – Manual Page 15 / 67

Exemplary SMS is as follows (if we use public network and provide server address
as IP):

1111█SERVER=89.123.115.8█PORT=6780█APN=internet█UN=█PW=

Where:

█: space character

5. OPERATION

.A device can be configured to maintain communication via GPRS / UMTS / HSPA
network or SMS messages. Communication mode is configurable – see chapter 7.
for more information. As a result the transmitter may be used only at the territory
covered with mobile phone operator network.

If status of inputs is the same as programmed one (NO or NC) a device stays
in a rest. Change of status on any input results in immediate signal transmitting of
this event by the device.

Note:

Each device input (from IN1 till IN5) may be individually defined as on open one
(NO) or closed one (NC). It means that when in NO, input shorting will be an active
state and, a non-shorting will be an active state in NC.

To avoid an excessive cost of use related in particular to false alarms a device
possesses a programmable analysis of inputs.

All inputs respond only to states change which means that transmitting will
follow only if an active state is on input and maintains during programmed minimum
time. Maintenance of active state longer than a minimum time will result in single
indicating. Another input activation (another transmitting) is possible only after
input reached based state.

Number of messages sent in SMS mode is limited (limit includes also text massages
or answers to orders sent by user).This function provides for cost reduction by
limiting messages e.g. in case of damage of sensor connected to any input. After
passage of programmed time new messages will be sent but only in a number
determined by the user.

Text message on events sent to private phone numbers may be edited.

LX20B transmitter is equipped with input of a PSTN telephone line, and input
to connect telephone communicator module of alarm control panel.

Module constantly controls availability of an external telephone line. Decrease
of line voltage below around 5V is deemed as a line damage. If an exterior phone
line is operating, it is provided for output of telephone communicator module. If
damage of urban line follows, a module disconnects a urban line and provides a
voltage simulating telephone line to output of telephone communicator module.
Module always provides voltage corresponding to operating phone line for an alarm
control panel (namely to phone communicator module) regardless of urban line
status.

LX20B – Manual Page 16 / 67

Configuration of transmitter for cooperation with an control panel’s phone
communicator requires entering into memory a phone number for which transmitter
is to answer.

Once a phone is picked up via an alarm control panel telephone
communicator , a telephone number is being dialled to make connection. After the
control panel dialled a number to which transmitter is to respond, a transmitter
takes over a phone line namely disconnects a urban line from an control panel and
provides to a phone communicator voltage that simulates an operating phone line.
Next it generates confirmation signal and awaits for data from a control panel –next
DTMF tones generated with communicator are treated as data. After transmitting
adequate number of DTMF signs (16 for ContactID) a transmitter generates Kissoff
signal. Collection of data from control panel finishes at hanging up a phone of a
control panel by phone communicator module. After that transmitter comes back to
standard operation –namely if urban line is operating, it is being connected to an
alarm control panel and awaits for dialling of new number.

If telephone number dialled with communicator is other than number GPRS
module answers, no operation follows and it waits until communicator hangs up a
phone and picks it up again – since picking up a telephone number dialled with a
communicator module is being checked.
All programmable parameters are saved in memory and in case of voltage
drop that are not lost. Supply of power starts the transmitter with saved settings.

6.3.2. File -> Open

If file contains saved settings, they may be used to program next device. Firstly a
catalogue where file has been saved shall be chosen and then name of file shall be
provided. Obtained data collection may be modified by the user. Any amendments
are effective if send to device.

6.3.3. File -> Save

During programming many devices in different configurations, it is not necessary to
have in mind each one as it may be saved on hard disc or floppy disk under any
name and it may be loaded later on. This function save on disc any information from
configuration wizard window. After activation of function a dialog window appears

LX20B – Manual Page 19 / 67

with request to provide file name. Default data is saved with CMI extension
(Configuration Memory Image).

6.3.4. File -> Language

Allows for selection of any available languages (determined in attached exterior
language files).

6.3.5. File -> Connections

Before programming of devices, a connection type shall be defined. It is possible to
do it with two methods:

- locally

- remotely

6.3.5.1. Local connection

Local connection means that configuration software (namely computer on which is
installed) is directly connected to proper terminal of transmitter via special wire and
through RS-232 serial port (GD-PROG) or USB port or Bluetooth (MINI-PROG-BT,
SP-PROG-BT). All channel connection (also USB and Bluetooth) "open" virtual COM
serial ports used in communication control panel-Configurator.

To program device or make any other operations (e.g. reading of device settings,
firmware amendments, etc.) it is necessary firstly to define connection parameters.

For the above purpose you shall use the following window, available after activating
File option from the Main Menu and selecting Connection function or after clicking on

icon on a taskbar and opening RS232 tab.

Define:
Name of connection e.g. Local
Choose serial port e.g. COM1

Click on [Add] button to confirm settings. Connections shall be saved (and inserted
in table). From this time on program shall enable wires connection with device and
reading, and saving of parameters in LX20B memory will be possible.

LX20B – Manual Page 20 / 67

In the next tab "MINI-PROG" (the name derived from the programmer) you have to
also define the connection parameters.

Operations are the same as with the "RS232" tab. Specify the name, the correct
COM port and add a connection.

Programmers MINI-PROG-BT and SP-PROG-BT have microUSB ports, through which
we can connect to the computer using the USB port, but also have built-in Bluetooth
interface.

6.3.5.2. Remote connection

As provided above the device and software makes for complete configuration with
GPRS / UMTS / HSPA link or CSD channel. This programming mode requires
definition of linking parameters.

GPRS link

Activate file in Main menu and select Connection function (or after clicking on
icon on fast access bar) and click on GPRS tab to carry out configuration of this
mode.
On screen the following window shall appear:

Define:

 Name of connection e.g.: Remote 1
 Select name of analyzer e.g.: Primary
 Enter analyzer address e.g.: www.ebs.pl

LX20B – Manual Page 21 / 67

 Enter port on which analyzer operates e.g. 9000

Click on [Add] button to confirm settings. Connections shall be saved (and inserted
in table). From this time on program shall enable remote connection to device and
reading and saving of parameters in LX memory shall be possible.

Notice: The following parameters: analyzer name, analyze address, port
relate to settings of OSM.Server receiver of monitoring system. Remote
programming is available only if above mentioned device (or software) is
used.

CSD link

Activate file in Main Menu and select Connection function (or after clicking on
icon on fast access bar) and click on GSM Modem tab to carry out configuration of
this mode.
On screen the window shall appear where it is possible to define:

 Name of connection e.g. Remote CSD
 Serial port where GSM modem is connected (e.g. Wavecom Fastrack)
 PIN code of SIM card installed in GSM modem e.g. 1111
 Serial port parameters: amount of bytes/sec. (e.g. 115200), data bytes (8),

parity (none), stop bytes (1)

Click [Add] button to confirm settings and save connection (settings are inserted
into table). Since that time a remote connection to device, reading and saving of
parameters in LX20B memory is possible.

Note: Remote configuration with CSD channel is possible if option of CSD data
sending has been activated both for SIM card inserted into a device and SIM card
installed in GSM modem. In addition, the transmitter must have turned on
permission to receive CSD data calls, see item 7.5.2. GSM modems authorized
phones.

Programming with CSD is also possible if OSM.Server system has been installed,
and minimum one GSM modem is connected. If device has been entered onto
server list (factory number and SIM card telephone number –See OSM.Server
Operation Manual) it is possible to use link via OSM. It is possible if device is not
connected to the OSM.Server via GPRS. During programming procedure (with GPRS
link- See above) a question will be displayed if user want to use a modem

LX20B – Manual Page 22 / 67

connected to the server. After confirmation procedure will follow as in case of other
programming channels.

6.3.6. File -> Automatic device settings backup

All configuration settings including reread from devices and saved on devices are to
be automatically saved on hard disc. If during installation on configuring tool
settings have not been changed, files will be saved as follows:
C:\Program Files\ EBS\KonfiguratorLX\configs\LX20B_20000
Catalog LX20B_20000 contains all files in respect of LX20B with factory number of
20000 programming. The name contains date and time of operation and its type
(saving/ reading). Files have .cmi extension.

6.3.7. File -> Exit

Finishes program operation.

6.3.8. Operations -> Read

Function reads data saved in memory of GPRS module. Exchange of data follows on

port selected in section “Select Connection Type” (See below description of option
”Configuration”). Correct reading is confirmed with message on a screen. Data

downloaded from device may be saved on file (see clause 6.3.3) and use for other
devices.
To use this function it is necessary to define type and parameters of connection.
E.g. for local connection the following view is displayed:

where:
Connection kind – serial port to which module is connected
Access code- service code of transmitter

Detailed description of connections configuration is included in clause 6.3.5.

6.3.9. Operations -> Send

This function is analogical to the above one, at the same time it enables data saving
into EEPROM module. There is also possibility to set correct time into LX20B device.
For this purpose, select "Set Time" and enter the appropriate date with the time.
Correct saving is confirmed with message on a screen.

LX20B – Manual Page 23 / 67

7.1.2.2.2. Secondary server

This section concerns the backup server and the SIM card 2. Fields should be
completed with data by analogy with the primary server.

LX20B – Manual Page 30 / 67

7.1.3. Communication

After completing of data in the Servers tab, the gray box will display the address
and port of the primary and secondary server.

7.1.3.1. Mobile Data Transmission

If GPRS or GPRS & SMS working mode is selected for one of the servers, you can
define the parameters related to the connections between the device and the server
via GPRS in this section.

7.1.3.1.1. Primary server

Interval between subsequent connection attempts

Programmable and equipped with SIM card device will try to make automatic
connection with server. In this field you define interval (in seconds) after which next
connection will follow if the previous connection failed.

Number of connection attempts before switching to the other server

In this filed you determine how many times device will try to make connection to
server. If connections fail, LX20B after execution of some connection will start
procedure of connection to back up server. This option is active only if we define
parameters of backup server.

LX20B – Manual Page 31 / 67

7.1.3.1.2. Secondary server

Interval between subsequent connection attempts

If device can not connect to primary server defined this after exhaustion for him
number of attempts, it will begin realizing the procedure of connecting to backup
server. We in this place define space of time (in seconds), after which test will
connecting renewed if previous finished with failure.

Number of connection attempts before switching to the other server

In this field you determine how often device will try to make connection to backup
server. If connections fail, LX20B after execution of some connection will back to
procedure of connection to primary server.

Disconnect after

If you mark this choice field the device will disconnect from back up server after
passage of set time. Further operation depends on defined parameter Order of
connection (See clause 1.1). If this option is active the device reconnects to the
primary server. If this option is not active the device firstly completes connection to
backup server procedure and if this fails, the device will try to connect to the
primary server.

7.1.3.1.3. Test events period

The device sends message “Test” with determined interval that informs monitoring
station that the device is in operation mode. In this field you can determine how
often this message will be sent (in seconds)

7.1.3.1.4. Start with Primary Server after connection failure

Mark this check box means, that the device will try in first order to connect to
primary server, without regard on definition of parameters for backup server
(especially number of connection attempts).

7.1.3.2. SMS

If SMS or GPRS & SMS working mode is selected for one of the servers, you can
define the parameters related to the connections between the device and the server
via GPRS in this section.

7.1.3.2.1. SMS mode after failed connection attempts attempts

Define number of reconnections to server. If during all reconnections fail the device
will go into SMS mode. In this mode LX20B will try to make connection with server,
according to interval defined in clause.

7.1.3.2.2. Test events period

This function is analogical to GPRS. It is activated when problems with GPRS
transmission follow when the device automatically goes into SMS mode (it relates to
operation mode in SMS). Usually it is undesirable to send text as SMS so often as

LX20B – Manual Page 32 / 67

with GPRS transmission. Parameter this allow for significant extension of distance
between tests (time in minutes) or completely interlocking of this option.

7.1.3.2.3. Send events immediately

In case of GPRS/3G connection lost device will send SMS reports immediately, even
if the LX20B isn’t in SMS mode yet.

7.2. TRANSMISSION

For the purpose of maximum security of transmission, data is encrypted with AES
key. This option may be used for GPRS and SMS transmission.
After selection of encrypted transmission you may use your own code (256 bytes –
signs 0-9 and A-F) or use default settings.

7.3. INPUTS/OUTPUTS

Transmitter has got 5 signal inputs. Module is equipped with two outputs.
Inputs/Outputs option enable programmable configuration so that transmitter
operates pursuant to requirements of the user.

7.3.1. Inputs configuration

For every input the following settings shall be determined respectively.

7.3.1.1. Input mode

LX20B – Manual Page 33 / 67

The parameter describes input configuration and stable state of input. Any change
of that state causes alarm message to be sent. The following configuration types are
available: NO / NC / EOL-NO / EOL-NC / DEOL-NO / DEOL-NC. NC type input must
be closed for the whole time. Line interruption causes its induction. NO type input
remains open. It activates when closed. EOL and DEOL (single end-of-line resistor
and double end-of-line resistor) differ with 1 or 2 resistors allowing distinguishing
alarm from sabotage. Electric diagrams for all configuration types were described in
chapter 3.4. INPUT CONFIGURATION.

7.3.1.2. Delay

This parameter means minimum time for change maintenance at input so that it
would be detected by transmitter. Factory setting is 400 ms.

7.3.1.3. Locks

With this option you can lock any input of transmitter, and as a result condition
changes on this input will be ignored and will not be reported to monitoring station.
Lock may be persistent or temporary.

In case of temporary lock – user can set lock time and number of input state
changes after which lock occurs. Lock time is counted from first input state change.
More detailed information about input locks is shown on a diagram below.
Both types of lock can be deactivated by SMS command (see RLIMIT command
described in chapter 9).

LX20B – Manual Page 34 / 67

- Locally there can be 2 x N – 1 input activations. In summary average number of activations during defined period of time will be preserved.

- N and Tb parameters may be set per input

LX20B – Manual Page 35 / 67

7.3.2. Partitions

Partitions are configured using Partitions tab.

7.3.2.1. Partition arming input

Using this option, partition arming input can be selected. To selected input, arming
device (e.g. switch, remote controller receiver or coded lock) can be connected.
When this input is violated (armed), the partition is armed (after Exit Time). When
arming input is not violated (disarmed), partition is disarmed.

7.3.2.2. Inputs assigned to partitions

Assigning input to partition means that it is monitored only when partition to which
input belongs is armed. Input can be assigned up to one partition. Arming inputs
can not be assigned to any partition. If input is not assigned to any partition, it acts
as 24 hours input – it is monitored regardless of partitions state.

7.3.2.3. Delayed inputs

Here, delayed inputs can be selected. Delayed input switches on associated output,
ie. generates alarm, after expiry of Entry time, but only when partition to which
input belongs will not be disarmed before Entry time period.

LX20B – Manual Page 36 / 67

7.3.2.4. Exit time

Partition exit time. Partition inputs will be monitored when this configured time
elapses after partition input had been armed.

7.3.2.5. Entry time

Time after which alarm will be generated after delayed input had been armed and
partition to which delayed input belongs will not be disarmed.

7.3.3. Outputs

Tab „Output 1 (OUT1)” and „ Output 2 (OUT2)” specify conditions of switch outputs.
Settings for all outputs are identical so they will be described in one chapter.

7.3.3.1. Activation mode and timing

Thanks to this option you may choose output operation mode. There are two
operation modes available:

o Bistable – connection follows for indefinite time – up to the moment of

disconnection of power for module or remote command which switches
output off,

o Monostable – connection follows for time defined by user – every 100ms.

7.3.3.2. Conditions

LX20B – Manual Page 37 / 67

Defines conditions for activating both of outputs. User can set following conditions:

o No connection to server (immediately after detection);
o No GSM signal (immediately after detection);
o Detection of incoming call from defined telephone number;

After selecting this option can be generated CLIP event, if appropriate
position in the “Monitoring” group is set (see item 7.4.5.). You can enter full
phone number or only a part of number. The device will detect all numbers
with specified sequence. E.g. if entered number is 1234, the output will
activate after incoming call from number 123456789 or 600123456.

Note: The phone number must me entered without country code (e.g.
without prefix 0048 and +48).

o Dependent on state transitions from non-active to active of one of the inputs.

Outputs can be also activated by internal watchdog, which can be configured in
“Link control” group (see chapter 7.7.).

7.3.3.3. Additional conditions

If option “Dependent on state transitions from non-active to active of one of the
inputs” is chosen, we might configure additional conditions for output activations:

o Never: input disturbance does not cause operation of sabotage output,
o No network: input disturbance causes actuation of sabotage output if

sending of information to server is impossible.

o Always: every input disturbance causes actuation of sabotage output.
o Available network: input disturbance causes actuation of sabotage output if

sending of information to server is possible.

Note: Both outputs may be controlled by SMS commands.

7.3.4. Advanced outputs control

The user is able to determine an alternative course of action to go over basic
outputs configuration function described in section 7.3.3. Outputs. In the “Advanced

outputs control” you may define separately the behavior of each of the outputs,
depending on events taking place. “Advanced outputs control” differs from the
existing basic “Outputs configuration” by:

o it is possible not only to turn on but also to turn off the output
o output can be activated temporarily for specified amount of time
o there is a complete list of events for which you can define the behavior of the

output

Note: Do not use at the same time the basic configuration of outputs (7.3.3.
Outputs) and the “Advanced outputs control”!

In particular, the basic configuration of existing options: “No GSM signal
(immediately after detection)” and “Dependent on state transitions from non-active
to active of one of the inputs” should not be used with their replacements “[Off]
GSM” and “[On] Input x”. The use the basic configuration of outputs and “Advanced
outputs control” at the same time, may cause unexpected behavior of the

transmitter.

LX20B – Manual Page 38 / 67

7.3.4.1. Output 1/Output 2

These columns define which signals are to influence the status of a specific output.
You can define the output operating mode and which signals control the outputs.
Available options for the output mode:

o Do Nothing – output status will be not changed (default action)
o Turn on output – output will be permanently turned on
o Turn on output temporarily – output will be turned on for an amount of time

specified by parameter 7.3.4.2 Time of output activation

o Turn off output – output will be turned off

Press the [Reset] button to assign the action “Do Nothing” for each event.

The output state does not change if the current state of the output coincides with
the result of the action.

7.3.4.2. Time of output activation

Parameter defining amount of time for which the output is to be turned on for the
functions of advanced outputs control.

LX20B – Manual Page 39 / 67

7.3.4.3. Event: CLIP

Icoming call from the number defined in option: Inputs/Outputs –> Output 1
(OUT1) / Output 2 (OUT2). The phone number is entered at option: “When icoming
call detected from number” (see item 7.3.3.2.).

7.4. MONITORING

Thanks to this option you may determine which of available signals generated by
the device shall be transmitted to monitoring station.

NOTE: “Configuration changed” event refer to configuration changes made

by SMS or GPRS commands.

7.4.1. GPRS On / GPRS Off

In this column you define signals that are to be reported to monitoring station with
GPRS transmission. There is possibility to send information on alarms (input state
change from rest to action status) and on returns of input state from action to rest
(normalization).
To transmit any signal you should only click it (proper square on your right).
Click on [Clear] button to remove all marked signals.
Click on [Invert] button to change markings to contrary.

7.4.2. SMS On / SMS Off

LX20B – Manual Page 40 / 67

In this column you define signals that may be reported at monitoring station with
SMS messages – when there is no connection with server over GPRS. There is
possibility to send information on alarms (input state change from rest to action
status) and on returns of input state from action to rest (normalization).
To transmit any signal you should only click it (proper square on your right).
Click on [Clear] button to remove all marked signals.
Click on [Invert] button to change markings to contrary.

7.4.3. Skip initial state

This option allow for locking of sending of information on status of active inputs at
power connection. Information on inputs will be sent to server after the first change
from inactive to active status.
For the events “Power” and “Battery” no selection “Skip initial state” will cause
sending information about the power supply / battery on boot device regardless of
the power supply / battery state.

7.4.4. Power loss

One of device additional options is monitoring of power supply voltage. As short
voltage drop may follows at some facilities, it is possible to avoid reporting by
entering time after which information will be sent.
Value of this parameter means that voltage drop shall follow within this determined
time so that device recognizes it as real voltage drop and that information might be
sent.

7.4.5. Event: CLIP

Icoming call from the number defined in option: Inputs/Outputs –>Output 1 (OUT1)
/ Output 2 (OUT2). The phone number is entered at option: “When icoming call
detected from number” (see item 7.3.3.2.).

7.5. RESTRICTIONS

In this section you can define the limits for the numbers of which SMS are sent to
the transmitter with commands and CSD connections are established. You can also
specify the period of validity of the sent SMS and SMS limits.

7.5.1. SMS Authorized phones

transmission should be GPRS this limitation is essential to reduce costs.

Mark field [Turn on SMS limits] to activate access to information groups that
shall subject to limitation:

 SMS test to server
 SMS event s sent to server
 SMS events sent to user
 Answers to commends

Limitation are defined by providing two values:
 SMS maximum number: determines maximum number of sent SMS messages per
time unit (see SMS counter reset). This option protects user against sending too
much of SMS messages e.g. in case of failure.

 SMS counter reset: This parameter determines time schedule (in minutes)
according to which counter of sent SMS messages will be zeroed.

7.6. SMS NOTIFICATIONS

User may define messages that in case of any event (e.g. input state change) will
be sent to private phone numbers. At the same time it is worth to remember about
limitation in this respect.

LX20B – Manual Page 43 / 67

7.6.1. Phone numbers

One way to limit amount of sent information (by SMS) is to define a list of 5 private

The device is able to forward received SMS messages according to the specified rules. This function may
be helpful for example when GSM operator sends messages with account state to SIM card installed
within device. In this window you may provide up to 5 rules.

Each rule contains a pair: part of sender phone number and correct recipient phone number. In some
cases a part of sender phone number may be an empty string which means that any phone number
matches to the rule. All rules are processed with given order. It means that in some cases one SMS
message may be forwarded to more than one recipients and/or some of them may be forwarded more
than once to the same recipient. The second case may occur when there are at least two rules with the
same recipient phone number and their part of sender phone number matches with message sender
phone number.

Note: It is a user’s responsibility to provide correct rules which will not create loops
of forwarded SMS messages.

LX20B – Manual Page 47 / 67

If RS232 checkbox will not be enabled, data to the Event monitor will be sent on
device’s serial port. With this setting, GD-PROG cable can be used to observe device
state using GPRS transmitters configurator application and Monitor option described
in point 7.11.

7.8.2. Buffer flushing

LX20B – Manual Page 50 / 67

Data received from connected device are stored in transmitter buffer. Buffer
capacity is 511 bytes. Define criteria that meeting shall mean data transmission to
monitoring system transmitter. The following options are available:

- After receiving ASCII character

- After expiry of defined time

- After receiving defined amount of characters

For every option list of available values are provided, and they me be scrolled down
after clicking on adequate arrow.

The transmitter controls buffer contents in respect of meeting of determined
criteria. It is performed with the following order: selected character, time, number
of characters.
Discharge of buffer (transmission) follows if one criteria is fulfilled.

7.8.3. Advanced port options

7.8.3.1. Disable data receiving

This option allow for lock of data received from device connected to RS-232 port of
transmitter. It is used in case of failure or situation when LX is being used to control
the device.

7.8.3.2. Disable data sending

This option allow for lock of data sending to device connected to RS-232 port of
transmitter. This prevent accidental or unauthorized controlling of the device.

7.8.3.3. Half Duplex mode

This option provides for automatic lock of data receiving (via RTS) if transmitter
begin to send data to the device. Useful for some RS-485 converters.

7.8.3.4. Tests of device connection to port

If the device connected to transmitter port generates periodical connection tests,
these tests may be under control. To provide for that (after this option activation)
enter text message and define frequency (in “Test presence every [s]” option).
Additionally user may determine if text messages will be sent to server. If this
option was not selected it is required to make sure that while the device connected
to transmitter port is not sending text message to transmitter, then transmitter
sends to server due message (See chapter 7.4. – Tests RS-232).

7.9. PHONE LINE

LX20B transmitter enables data transmission from control panel adapted to work
with external telephone line in case of lack of access to this line. The transmitter
receives information from the control panel through it’s telephone communicator,

LX20B – Manual Page 51 / 67

then transmits them by one of the available links: GSM/ GPRS/ UMTS/ HSPA/ SMS.
For proper device operation you need to define the parameters described below.

7.9.1. Phone line

This tab is provided to determine settings of telephone line.

7.9.1.1. Use external phone line

If this function has been chosen (Activation) the transmitter will be cooperating with
PSTN line. This way data transmission is possible from an alarm control panel with
two ways: via GPRS link and standard telephone line.

7.9.1.2. Disconnect external phone when server connected

If enabled, PSTN line will be disconnected from T1-R1 port when connection with the
server is established. If events registered by the alarm control panel are supposed
to be sent by GPRS, this option can be used to separate external line from the alarm
control panel.

7.9.1.3. Monitor external phone line voltage

If transmission with two ways follows, it is necessary that operator of monitoring
system received information on access to an external telephone line. Choice of this
option will result in voltage drop on telephone line (longer that defined minimal time
of decay) that will be signalized with an adequate message sent via GPRS.

LX20B – Manual Page 52 / 67

Note: The transmitter is to simulate a telephone line access if:

o A PSTN line is not connected
o A PSTN line is connected but has not been activated option from clause 7.9.1.1.
o Options from clause 7.9.1.1. and clause 7.9.1.3. are active and voltage on

terminals TIP-RING decreased below 8V.

7.9.1.4. Report off-hook

If a phone set is connected in parallel output of control panel communicator (to
terminals T1-R1 of transmitter), picking up of a phone prevent from exchange of
data between an control panel and a transmitter. There is possibility to control this
situation. Choice of this option result in sending a report to monitoring station if
time of picking up the phone exceeds determined time limit.

7.9.1.5. Report intervals between dialled digits

This option is being used if in configuration “PSTN line – LX20B – Alarm Control
Panel” there are not other telecommunication devices. If such device will be

connected and telephone number will be dialled (and a call will follow) after expiry
defined time limit (counted since conclusion of last digit dialling) the transmitter
sends a message. This operation prevents unauthorised installation of additional
devices.

7.9.1.6. Generate dial tone

Some alarm control panels require that during a receiver picking up a tone of
dialling was actuated. To enable cooperation with a transmitter it is possible to
make a transmitter to generate such tone.

7.9.1.7. Detect off-hook

The default value for the delay detection off-hook is 100ms. You can define your
own delay value by choosing option "After" and giving the number in milliseconds.

7.9.2. First and Second phone number

To provide for proper cooperation between a transmitter and a control panel in
DTMF mode determination of some parameters is required. The below described
functions are analogous to the both telephone numbers that may be saved in the
device memory.

7.9.2.1. DTMF phone number

This is a number that has been saved in memory of an alarm control panel. If the
panel is to transmit information on an event it shall dialled this number.
Transmission of this information via GSM (GPRS) will be possible if this number will
be identical as a number entered into the transmitter.

LX20B – Manual Page 53 / 67

7.9.2.2. Handshake delay

This defines time after which a transmitter generates confirmation to an alarm
control panel for correct phone number dial. Default setting is 2.0 sec. European
Standard determines this value at 0.5 to 12.5 sec.

7.9.2.3. Protocol

Select protocol of data transmission used by an alarm control panel and that is
acceptable for monitoring station. Available options: ContactID.

Note:

1) For all protocols you may use following options:

o [Enable SMS sending] which means that in case of no GPRS connection,

data will be sent via SMS (if this mode will be accessible).

o [Don’t transmit data when external phone line is available] which means

that when the external PSTN line is available then it will be used during
transmission from the control panel.

2) [Disable CRC checking] option may be used for ContactID format. Some control
panel generate improper messages regarding a control sum for transmitted data,
the device is not able to confirm collection of data, and as a result the panel tries to
send them again (until execution of all determined trials). Select this option to avoid
the above mentioned.

LX20B – Manual Page 54 / 67
