2. LIMITATIONS OF USE
As the cellular telephones are designed for the best possible transmission of voice signals, it
is permissible that their data compression systems cause distortions of the transmitted audio
signals. For this reason, transmission of modem signals (downloading) through a simulated
telephone line may be impeded.
3. DESCRIPTION OF THE MODULE
MODULE TERMINALS:
+12V - power supply input (12V DC ±15%)
GND - ground (0V)
FLT - alarm output, SIM300C telephone failure or insufficient range (OC; 50mA)
R-1, T-1 - extension telephone line (connection to the alarm control panel or to a telephone
set)
The FLT output is a generalized fault indicator. It gets active if connection with the base
station is not confirmed by the module within 10 minutes. It may be caused by a telephone
trouble, antenna failure (antenna cable damage), or loss of range due to other reasons. The
fault alarm stops maximum 30 seconds after the alarm causes ceased to exist.

User Manual GSM LT-14

LEDs:
The module indicates its status to the user by means of 4 LED indicators. The mode of
lighting of the STAT and SIG LEDs depends on the module status and provides the
information described below. The lighting (ON) cycle of those LEDs lasts approx. 2 seconds
and is repeated every 3 seconds, which means that particular lighting cycles are separated
by at least one-second (OFF) interval.
STAT - indicates the module status by a corresponding number of flashes with specified
duration. Shown symbolically below are single cycles of various LED lighting
modes with their meaning described. The shaded fields meaning the LED "on" and
the blank fields – the LED "off":
- (LED off) module power off
- no PIN code
- wrong PIN code
- PUK code required
- no communication with SIM300C telephone
- active connection
- normal operation of module
- module restart on switching power on
- PH-SIM PIN code required
- no SIM card
- SIM card damaged
- SIM card busy
- invalid SIM card
- PIN2 code required
- PUK2 code required
- other errors

In its active state, the FLT output is shorted to the ground. The FLT output may be connected
to the alarm control panel input, or it can directly control the relay operation (its maximum
current-carrying capacity is 50mA).
Figure 3. Load connection to FLT output.
4. OPERATING THE SIM300C TELEPHONE
As any other cellular telephone, the SIM300C industrial telephone requires a SIM activation
card to operate. The user of the GSM LT-1S module and the SIM300C telephone has to
obtain such a card on his own. The SIM card should be inserted into a special recess
provided on the right-hand side of the printed circuit board. The PIN code, if necessary, is to
be entered into the module memory by means of a telephone connected to terminals R-1 and
T-1, or by means of a computer and the DLOAD10 program. The change of PIN code stored
in the SIM card, or entering the PUK code is possible after putting the SIM card into an
ordinary cellular telephone.
The PUK code can also be entered into the SIM card from an ordinary telephone set
connected to the module terminals R-1 and T-1 (section 9.2, by means of the programming
function 16), however, it requires that the PIN code previously saved in the GSM LT-1S be
entered into the SIM card. (section 9.2, function No. 01)
When making connection, the telephone transmits its own identifier (ID), unless this option is
reserved at the GSM operator (change of option is available via ordinary cellular telephone).
The SIM300C cellular telephone is fitted with a special cable, terminated with connector for
external antenna (see Fig. 2).
5. INSTALLATION
It should be borne in mind during installation that the GSM LT-1S module must not be located
in the vicinity of electrical installations, since this may involve a risk of malfunctioning. Pay
special attention to how the cable is laid between the module and the telephone terminals of
the alarm control panel.
Never turn on power supply of the module and SIM300C telephone without
external antenna connected.

User Manual GSM LT-16
The installation must be carried out in a strict compliance with the following activation
procedure:
1. Make a complete wiring.
2. Turn on the module power supply without SIM card inserted.
3. Using a DTMF telephone set or the DLOAD10 computer program, specify the module
working parameters (including the PIN code).
4. Turn off power supply.
5. Insert SIM card into the socket (see Fig. 4).
6. Turn on power supply.
Figure 4. Entering the SIM card into its socket.
The module power supply should have a sufficient current capacity. The recommended
power supply unit (e.g. APS-15; APS-30 manufactured by SATEL) should be equipped with
its own battery.
It is suggested that the power supply be located within 3m from the module.
If the supply voltage is lower than 9.8V, restart of the module will follow. Therefore, be careful
that the module supply voltage never drops during operation below 9.8V at the maximum
current consumption.
6. OPERATION OF THE MODULE WITH ALARM CONTROL PANEL AND STATIONARY
TELEPHONE
As shown in Figure 1, the module is to be directly connected to the output terminals of the
control panel telephone circuit. It maintains impedance and voltage across the R-1 and T-1
terminals as necessary for correct operation of the telephone set. The terminals can be
automatically deenergized in case of a loss of communication with the base station (which is
accompanied by operation of the FLT trouble indicator – see: programming function No. 17).
When the control panel goes „off-hook”, or when a user lifts the handset of a telephone
connected to the terminals T-1 and R-1, the module will generate the continuous dialing tone
and receive the tone or pulse dialing signals (similarly as the telephone exchange). The
telephone number can include digits and special characters: # *+. The phone number should
be dialed just like from a cellular phone, as required by the operator of the network into which
the telephone is logged. It is recommended that the number begin with the „+” character and
country code prefix (48 for Poland). Sometimes you can dial just the mobile phone number,
or the area code and stationary telephone number..

Examples:
[*][0][4][8][5][0][1][1][2][3][4][5][6] – connection to mobile phone (with prefix „+48”)
[5][0][1][1][2][3][4][5][6] – connection to mobile phone (number without prefix)
[5][8] [1][2][3][4][5][6][7] – connection to stationary telephone, (in this
example, 58 is location area code)
If the first four digits of the dialed number correspond to the pre-programmed „pager station
number”, the module goes to the procedure of receiving the alphanumeric message and
sending it as an SMS text message (see section „Sending SMS messages”). Checking of
the first four digits is always performed.
When connection is established by the cellular telephone, the module will transmit LF audio
signals between the extension line T-1, R-1 terminals and the cellular telephone. After the
handset is lifted by the subscriber the connection is established with, the module changes the
direct voltage polarization across the extension line terminals T-1 and R-1. This function
makes it possible to keep individual tariffication of phone calls.
An option is provided for calling the phone number of the module SIM card. The incoming
calls to the SIM300C cellular telephone are directed to the extension line terminals R-1 and
T-1, which generates the ringing tone, in much the same way as with operation of the cable
telephone line. It is then possible to answer the incoming calls by means of a stationary
telephone set connected to that telephone line.
7. GSM LT-1S WITH MONITORING STATION
Figure 5.
The GSM LT-1S module permits site monitoring by means of SMS short text messages. This
function is offered by the STAM-1 monitoring station program, version 4.07 and STAM-2,

User Manual GSM LT-18
manufactured by SATEL. The example of module connection to station is shown in Fig. 5.
The STAM-1 TRNK expansion board can also be used to connect the module.
Connect the GSM LT-1S module to the computer serial port (COM1 or COM2) or,
alternatively, to the RS-232 port on the expansion board, by means of the typical cable for
programming the CA-10, CA-64 or INTEGRA control panels.
To make the module interface with the monitoring station, you must enter during setup the
communication code, by default 111111. The contents of SMS-messages and the
corresponding codes are to be defined in the STAM-1/STAM-2 program when editing the
client.
8. SENDING SMS MESSAGES
An alarm triggered at the protected site can initiate the mode of telephone messaging
through the alarm control panel. If the control panel has the function of messaging to the
pager system, it can be used for sending SMS messages to the cellular telephone number.
The message then sent by the control panel is transferred to the GSM LT-1S module, not to
the pager station. For example: the alarm control panel CA-64 or INTEGRA can send
messages to three different paging systems. If one of them is assigned to operation with the
GSM LT-1S module, the remaining two can perform their normal function.
To enable sending the SMS messages, program in the GSM-LT module the telephone
number of Short Message Service Center (function 02 and 10) and telephone number of
pager station (function 06), and in the alarm control panel the telephone number of pager
station, as required, and enter into the control panel memory the appropriate text to be sent.
The telephone number to be programmed in the control panel must consist of:
1. The "pager station number" pre-programmed in the GSM LT-1S module.
2. The cellular phone number to which the SMS message is to be sent (with the country code
prefix, but without the „+” character).
3. The end-of-number character (it is „A” in SATEL control panels).
Note: Parts of the number may not be separated from each other by any time interval (pause);
the digits must be sent by the control panel as one sequence in DTMF or pulse mode. In
case the module has any trouble with receiving the „pager” station number in the tone
mode, it is necessary to set the pulse dialing mode in the control panel.
8.1 PROCEDURE FOR CONVERTING PAGER MESSAGES INTO SMS MESSAGES
After the alarm control panel goes “off hook” and the number has been dialed – the module
checks the first four digits of the number. If they coincide with the “pager station number”
programmed in the module, then the module will send a handshake signal (similarly as the
pager station) and receive the message sent by the control panel. Next, this message is
transmitted via the SIM300C telephone as an SMS text message to the number received
from the control panel (the second part of the control panel programmed number).
Note: The programmed “Pager station number” must be unique and must not coincide with
the beginning of other telephone numbers.
The SMS sending systems may require adding a prefix with the country code (48 for Poland).
The prefix (without „+”) is to be programmed together with the cellular phone number.
To enable the transmission of SMS messages, the “SMS center No.”, must be loaded into
the module, depending on the GSM network where the telephone is activated. It must be
preceded by the „+” character and the country code suitable for the operated network.

GSM LT-1 SATEL 9
Parameters of the pager system signal should be programmed at the alarm control panel
(or the DT-1 telephone set) as follows:
control panel 1 C 2 2 0 A 0 E 7 0 8 A
DT-1 C 1 2 2 A 0 E 0 0 7 A 8
8.2 SENDING SMS MESSAGES FROM A STATIONARY TELEPHONE SET
The GSM LT-1S module user has an option to send SMS messages form a stationary
telephone set which generates DTMF signals and is connected to the terminals R-1 and T-1.
This operation is done in much the same way as sending SMS messages in the PAGER
system.
In order to send an SMS you should:
1. Lift the handset of the telephone connected to the terminals R-1 and T-1.
2. Dial in one sequence the "PAGER station number" and the phone number to which the
SMS is to be sent. The number should be entered rather quickly, without any time intervals
between consecutive digits. The addressee telephone number must be identical in form as
when receiving by the module of the PAGER message from the control panel (the country
prefix must be entered before the cellular phone number).
3. The properly received number is acknowledged in the handset by two beeps generated by
the module (the PAGER station responds in the
same way). Lack of acknowledgement or a busy
signal means a dialing error and then the
procedure must be started anew.
4. Enter the text of message following the
instructions below (the time of module waiting for
subsequent characters is not limited):
After calling the function, the module will accept
characters in the numeric mode. Pressing each
key of the telephone adds a corresponding digit to
the message.
By pressing the [*] key twice you will enter the text
mode. In the text mode, each numeric key (from 1
to 9) has three letters assigned to it (see figure 6).
Pressing a key means selection of the middle
letter. By pressing in turn the key and [*] you will
select the left-hand letter on the given key. The
right-hand letter is accessible by pressing the given key and [#]. In order to reach the
space, press the [0] key. To reach the dash, press [0][*], the point – press [1]. In order to
change between the text mode and the numeric mode, press the keys [0] and [#]. Pressing
the [#] key when the module is in the numeric mode results in ending the programming
and sending the message.
The GSM LT-1S can store in its memory 62 alphanumeric characters to be sent as an SMS
message. At an attempt to enter a longer message, the excessive portion of the text will be
omitted. There is no possibility to check the content of entered message. If you hang up the
handset when entering the text, the function will be interrupted without sending any SMS.

9. „CLIP” TEST TRANSMISSION
9.1 TEST TRANSMISSION WITHOUT ACKNOWLEDGEMENT
The CLIP type information makes use of the calling number presentation function and may
be used to confirm that the GSM LT-1S module is in good working order. This type of
messaging consists in dialing a programmed telephone number by the SIM300C telephone
and then breaking the connection after approx. 20 seconds. The message recipient can read
information on the number of the telephone from which the connection was initiated (cellular
phone, ISDN, etc.). If the number is busy, the module will repeat the call. The module will
consider the messaging completed, if it does not receive the busy signal within approx. 10
seconds from dialing the number. The cellular phone user has an option to early „reject” the
connection, but if he carries out this action too early, the module will repeat the call.
Answering the call, either by the user or automatically by the „voice mail”, is recognized by
the module as completion of messaging, however it entails a toll being charged by the
network operator. The module will use this function to complete the test transmission by
calling in turn each of the preprogrammed numbers. The phone numbers to be notified
should be programmed by means of functions 21 to 24.
When carrying out test transmission in the „without acknowledgement” mode, the module will
dial the given telephone number once (provided the number is not busy), irrespective of the
programmed number of test transmission attempts (functions 32-35).
As the module has no real time clock, the first test transmission will be carried out approx. 30
seconds after module programming is completed, the second one after randomly chosen
time, not exceeding however 20h or the duration of preprogrammed transmission time
(depending on which period is shorter). Further transmissions should be performed according
to the preset parameter. Use function 19 or 25 for programming time intervals between the
test transmissions.
When programming the test transmission data, remember to set the „test transmission
priority” (function 20), as appropriate.
Notes:
•If the cellular phone of the message addressee is OFF or outside the network range, and
the voice mail service is inactive, then an automatic message on the existing situation is
generated in the receiver and no busy signal is sent back. In such a case, the messaging
is considered by the module as completed, while the user loses information on completion
thereof.
•If the voice mail service is active, the user, after getting access to the network, may be
notified, depending on the operator (e.g. by means of an SMS) of the telephone
connection with the module number, without leaving any voice message.
9.2 TEST TRANSMISSION WITH ACKNOWLEDGEMENT
The transmission acknowledgement option (DLOAD10) and, if the transmission is not
acknowledged, the SMS send option (functions 36 to 39) can be selected for each of the four
telephone numbers to be programmed for the test transmission. The transmission
acknowledgement consists in the telephone user rejecting or receiving the connection set up
by the GSM LT-1S module. The acknowledgement can only take place within 10 to 20
seconds of the connection set-up. In addition, the number of attempts (1-15) to make the test
transmission (functions 32 to 35) can be programmed individually for each telephone
number. Having detected the acknowledgement of CLIP transmission, the module will finish
dialing the given telephone number. The module will call in turn each of the programmed
numbers, starting from the telephone no. 1. If, having completed the programmed number of

GSM LT-1 SATEL 11
attempts in the selected transmission mode with acknowledgement and SMS send, the
module fails to detect the acknowledgement, an SMS will be sent by the module to the given
telephone number. The message contents can be standard - „CLIP failed” or programmed.
The function 40 makes it possible to delete the message contents or to enter a default text,
while using the computer and DLOAD10 program you can type in any text.
9.3 SMS CONTROL
Provision is made for a remote change of the test transmission parameters. It is possible to
change the transmission period (function 27) and the telephone numbers (functions 28 to 31)
to which the transmission is effected. Such a change is possible by sending an SMS
message to the module. The module can inform the user about the performed change by
sending back an SMS to the telephone number programmed with the function 26. The sent
SMS contains information on the current settings (transmission period and 4 valid telephone
numbers for test transmission). For the module to send back the SMS, it is necessary to
program the SMS center number (function 02).
10. MODULE PROGRAMMING
For the module to operate properly, corresponding parameters must be programmed. The
programming is possible by means of a stationary telephone capable of generating DTMF
signals, or by using a PC computer and the DLOAD10 program (version 1.00.17 or later).
10.1 PROGRAMMING BY MEANS OF A TELEPHONE SET (DTMF)
The stationary telephone set makes it possible to program all the module operating
parameters by means of DTMF signals, as well as enables the module status and antenna
signal level to be checked.
In order to change the settings or check the status you should first enter the GSM LT-1S
module programming mode. This operation requires entering a six-digit access code. By
default, this code is 123456 and can be changed. In case you have forgotten the code after
the change, you can only view it or restore it by means of the computer and the Dload10
program.
In the process of programming, the module communicates with the user by means of beeps
that can be heard in the telephone handset. These beeps (tones) are symbolically denoted in
the function description by means of capital letters:
S- short beep
L- long beep
Calling the GSM LT-1S module programming mode:
•Lift the handset of the telephone connected to the module terminals R-1 and T-1 (the
telephone must support the DTMF tone system).
•Select the following key sequence on the keypad:
[*][*][*][*][*][*][?][?][?][?][?][?][*][*][*][*][*][*][#]
(6 x asterisk; access code; 6 x asterisk; # )
•The module will confirm entering the programming mode with four short and one long
beeps (SSSSL) hearable in the telephone handset and will wait for individual functions to
be called to program the settings. It will remain in the programming mode until the handset
is hanged up.
Note: The module accepts the call of programming mode irrespective of the signals it
generates in the handset (e.g. the line busy signal can be heard, if there is no SIM
card inserted).

User Manual GSM LT-112
Programming the module settings
In order to call the programming function, select the function number (two digits), press the
[*][*] asterisk key twice, enter the parameter suitable for the given function and press the [#]
key.
The parameter keys are described by means of the [?] question marks. The number of
question marks is equal to that of the digits of the parameter to be entered in the given
function. Where the number of digits is not precisely defined, then such a parameter is
described with the [?...] symbol (e.g. telephone number).
The numbers of telephones/ PAGER stations may contain special characters: #, *, +. In order
to program such a character from the telephone keypad, call the programming function and
press successively the two keys:
[*][1] = #
[*][*] = *
[*][0] = +
Entering a correct command is signaled in the handset by three short beeps (SSS), while
commands which are incomprehensible or have an incorrect number of characters are
signaled by two long beeps (LL).
The function completed, the module returns to the programming mode. If you hang up, the
module will quit the programming mode and return to the normal operating mode.
10.2 FUNCTION LIST
[0][1][*][*][?][?][?][?][#] - SIM card PIN code (4 digits). The code saved in module
memory does not change the code stored on the SIM card.
The [0][1][*][*][#] sequence deletes the PIN code from module
memory.
[0][2][*][*][?...][#] - SMS center number - the telephone number necessary for
sending text messages. The number of its digits must be
within the range of 1...16. The entered number depends on the
GSM network, where the telephone is activated. It must be
preceded by the country code suitable for the operated
network.
The [0][2][*][*][#] sequence deletes the previously saved SMS
center number.
[0][3][*][*][?][?][?][?][?][?][#] - SMS password (6 characters) required for a remote change
of the modem format. Sending to the module of an SMS
containing the [?][?][?][?][?][?]=NN sequence will change the
modem operating format available in the SIM300C telephone.
The two NN digits define the format as described in the
function 08. Using DTMF signals it is possible to program a
password comprised of digits only (0...9), while using the
Dload10 program you can program a password comprised of
both letters and digits. The [0][3][*][*][#] sequence deletes the
previously programmed password.
[0][4][*][*][?][?][?][?][?][?][#] - SMS password (6 characters) which calls the SERV modem
command. The function applies to interaction between the
module and the CA-64/INTEGRA alarm control panel. Sending
to the module of an SMS containing the programmed
password makes the control panel call back to the number
saved in its memory as the "Dload64 telephone"/”DloadX

GSM LT-1 SATEL 13
telephone” in order to start the downloading function. If the
control panel is to call back to another number, the number
should be put into the SMC content as follows:
[?][?][?][?][?][?]=dddd. (password, equality sign, telephone
number, point). Using DTMF signals it is possible to program a
password comprised of digits only (0...9), while using the
Dload10 program you can program a password comprised of
both letters and digits. The [0][4][*][*][#] sequence deletes the
previously programmed password.
[0][5][*][*][?][?][?][?][?][?][#] - SMS password (6 characters) which calls the USER modem
command. The function applies to interaction between the
module and the CA-64/INTEGRA alarm control panel. Sending
to the module of an SMS containing the programmed
password makes the control panel call back to the number
saved in its memory as the "Guard64 telephone”/”Guard64
telephone” in order to start the remote communication with the
GUARD64/GUARDX program. If the control panel is to call
back to another number, the number should be put into the
SMS content as follows: [?][?][?][?][?][?]=gggg. (password,
equality sign, telephone number, point). Using DTMF signals it
is possible to program a password comprised of digits only
(0...9), while using the Dload10 program you can program a
password comprised of both letters and digits. The
[0][4][*][*][#] sequence deletes the previously programmed
password.
Note: The message sent to the module may contain just the SMS password, but it can also
be longer than the password (the password can be part of a longer word). It is
important that the password be inserted in the initial part of the message text (among
the first 32 characters). This feature makes it possible to load a verbal description of
the performed operation into the memory of the telephone from which the SMS will be
sent. Thus the user does not need to remember the passwords and their
corresponding functions.
Only one control password can be sent in one message. Sending an SMS without any
password will cause no reaction of the module. The received message will be deleted,
and the telephone will be ready for reception of a next text message.
[0][6][*][*][?][?][?][?][#] - PAGER station number (4 digits). If the module detects
these digits at the beginning of the dialed number, it will
handle the further part of the number as the number of cellular
phone to which it is necessary to send the SMS. The SMS
contents should be transmitted by the alarm control panel in
the "pager" system form. The [0][6][*][*][#] sequence will delete
the number.
[0][7][*][*][?][?][?][?][#] - CA-64 station number (4 digits). This function is not used. It
applies to interaction with the CA-64 control panel. The
[0][7][*][*][#] sequence will delete the number.
[0][8][*][*][?][?][#] - modem standard format (2 digits) - the format in which the
module will communicate with the modem of service / user
computer. The format code is to be entered as two digits
according to the table below:

User Manual GSM LT-114
format code modem format

71 9600 V.110/X.31
75 14400 V.110/X.31
[0]9][*][*][?][#] - RS-232 port speed. Parameter defining the rate of data
transfer between the module and the control panel / computer.
You should enter a digit to define one of the following rates:
0 – 4800 bps
1 – 9600 bps
2 – 19200 bps
[1][0][*][*][?][#] - SMS center international number. The option indicates
whether the programmed SMS center number is a full
international number.
0 – no (for local networks)
1 – yes (recommended)
[1][1][*][*][?][#] - Fax/Modem. Option indicating whether the user permits a
modem transmission to be carried out by the module. You
should program one of the following values:
0 – modem transmission disabled
1 – modem transmission enabled
[1][2][*][*][?][?][?][?][?][?][#] - access code (6 digits) for programming the module by means
of a telephone set. The [1][2][*][*][#] sequence will delete the
code i.e. deny the access to programming. When you delete
the code and quit the programming mode, you will only be
able to change the settings and restore the code by using
a PC computer and the Dload10 program.
[1][3][*][*][1][2][3][4][#] - restore default settings - the default access code for module
programming is 123456.
[1][4][*][*][#] - check antenna signal strength. The module, by means of
handset beeps, informs the user about the level of received

GSM LT-1 SATEL 15
antenna signal. The signaling is same as that of the SIG LED.
The following answer beeps are possible:
two long (LL) – antenna signal strength = 0
one short (S) – antenna signal strength = 1
two short (SS) – antenna signal strength = 2
three short (SSS) – antenna signal strength = 3
four short (SSSS) – antenna signal strength = 4 (maximum)
[1][5][*][*][#] - check telephone status. The module informs the user about
its status. The signaling is same as that of the STAT LED. The
following answer beeps are possible:
four short (SSSS) – no SIM PIN code
three short (SSS) – wrong SIM PIN code
short and long (SL) – SIM PUK code required
two short (SS) – no communication with SIM300C module
one short (S) – module operation OK
two long (LL) – module restart after power-up
two short and one long (SSL) – PH-SIM PIN code required
eight short (SSSSSSSS) – no SIM card
three long (LLL) – SIM card damaged
four beeps of diminishing length (LlSs) –SIM card busy
three short and one long (SSSL) – SIM PIN2 code required
four short and one long (SSSSL) – SIM PUK2 code required
one long, three short and one long (LSSSL) – other error
[1][6][*][*][?][?][?][?][?][?][?][?][#] - enter PUK code (8 digits) into the SIM card. This
function can only be performed when the module status
indicates (by LED or beeps) that the PUK code is required.
This code is not stored anywhere, but after entry it is
transferred to the SIM. When the PUK is entered and the
telephone is unblocked, the PIN code currently programmed in
the module settings will be loaded into the SIM memory.
If the PIN code has not been programmed at all in the module
settings, the PUK will not be transferred to the SIM300C. Entry
of a correct PUK code will be confirmed by three short beeps
(SSS) - this confirmation will appear after a few seconds' delay
because of the data processing in the SIM300C telephone.
[1][7][*][*][?][#] - deenergizing the telephone line together with signaling fault at
the FLT output:
0 – do not switch off voltage on telephone line terminals,
1 – switch off voltage on telephone line if FLT is active.
[1][8][*][*][?][#] - generating the routing signal (sound signal for setting up
connection):
0 – routing signal OFF,
1 – routing signal ON.
[1][9][*][*][?][#] - test transmission. The function enters the period of CLIP test
transmission in a simplified way. The following values can be
entered:
0 – no test transmission,

User Manual GSM LT-116
1 – test transmission 2h58min,
2 – test transmission 5h57min,
3 – test transmission period 11h56min,
4 – test transmission period 23h55min,
5 – test transmission period 2d23h53min,
6 – test transmission period 6d23h30min.
[2][0][*][*][?][#] - test transmission priority. This option determines whether
the test transmission will override the call being just carried out
by the module. If yes, the current connection will be terminated
whenever there is a need for the test transmission. If no, the
test transmission will be carried out on completion of the call
by the control panel/user:
0 – no,
1 – yes.
[2][1][*][*][?...][#] - telephone number 1 for the test transmission. The number
of digits must be within the range of 1...16. The number should
be programmed with „+” at the beginning, followed by the
country code. The [2][1][*][*][#] sequence will erase the
previously saved telephone number.
[2][2][*][*][?...][#] - telephone number 2 for the test transmission. The number
of digits must be within the range of 1...16. The number should
be programmed with „+” at the beginning, followed by the
country code. The [2][2][*][*][#] sequence will erase the
previously saved telephone number.
[2][3][*][*][?...][#] - telephone number 3 for the test transmission. The number

range of 1...16. The [2][4][*][*][#] sequence will erase the
previously saved telephone number.
[2][5][*][*][?][?][?][?][?][?][#] - test transmission period (6 digits: ddhhmm). As distinct from
function 19, this function enables any transmission period to
be entered. The programmed digits have the following meaning:
dd – number of days (max. 31),
hh – number of hours (max. 23),
mm – number of minutes (max. 59).
Programming zeros only will reset the test transmission.
[2][6][*][*][?...][#] - telephone number to confirm SMS control. The number to
which the module will send an SMS to inform about the current
settings, provided that the user has changed the settings by
means of an SMS. The telephone number must be preceded
by the „+” character and country code, corresponding to the
currently used GSM network.
[2][7][*][*][?][?][?][?][?][?][#] - SMS password (6 characters) makes it possible to remotely
change the test transmission period. Sending to the module
