1. Introduction
GSM-R5-Tx is a device designed for DIN rail mounting. GSM-R5-Tx can control one
independent electrical circuit in a building, e.g. one circuit of an accumulator stove or
circuit for entry gate or garage gate opening. The control is made via SMS messages or
by ringing. The device is ready to operate immediately after connection to power supply
and inserting of a SIM card of any GSM operator. The GSM-R5-Tx has one relay output,
which can control a coil of a contactor. An electrical appliance e.g. electric heating
system can be connected to this contactor. The GSM-R5-Tx has also one logical input
and one logical output. The logical input can be activated by external voltage 8 to
30VDC/AC. The GSM-R5-Tx can react on input status change by ringing or sending and
SMS on preset phone number. It is
also possible to readout the status
of this input via status SMS from
the GSM-R5-Tx. Analog input is
designed for
measuring the temperature or
current 0-20mA or voltage 0-10V.
Analog input can be used for
automatic regulation of output
OUT and can control connected
heating system to maintain the
preset temperature. The
temperature of a temperature
sensor can be readout via SMS.
2. Package
1pc GSM-R5-T or GSM-R5-TI or GSM-R5-TU
1pc GSM antenna GSM-ANT11K
1pc 8 pin connector (3.5mm), 1pc 2 pin connector (3.5mm)
1pc screwdriver 2mm
1pc mini USB cable
3. Recommended accessories
GSM-C-T2 temperature sensor with cable 1m
4. Instalation
1. To operate the GSM RELAY a SIM card of any GSM
operator is necessary. SIM card must be functional, active and must have PIN code
turned off. Also some credit is necessary if the SIM card is pre-paid.
2. Insert this prepared SIM card into the GSM-R2-T device (cut corner first, contacts
up –towards the inscription SIM). The correct insertion is indicated by mechanical
click noise. Push gently and release to remove the SIM card.
3. Now it’s possible to connect GSM antenna and power supply 12V or 24V to GSM-
R5-Tx. If the power supply is OK, the green LED (right from PWR connector) will
light on. Cca 1 minute later the blue LED diode GSM will start flashing with a
period of 4 sec.
4. To make the first test of the GSM-R5-Tx, press the button for local control of
output Y2(OUT). The green LED (near Y2) will light on. Than use your mobile
telephone which you want to use to control the appliance and send a SMS text
message 1234 ON to the telephone number of the SIM card inserted into the GSM-
R5-Tx. This will switch off the output Y2(OUT) and the green LED will light off.
GSM-R5-Tx automatically sends a confirmation message on performing the
operation. (You can change the password 1234 later in configuration)
5. Try “ringing” on device. You can make pulse on Y2(OUT) for ca. 4 seconds by
calling on GSM-R5-Tx (with factory settings). The device hangs up the call and
makes pulse on the output. This can be used for example for opening an entrance
gate. You have to use the same phone number as was in the very first SMS sent to
the device.
6. Try temperature regulation to 25°C. Output Y2(OUT) will be switched on and off
depending on the temperature input A1(°C). Connect the temperature sensor into
the temperature input A1(°C) and send SMS in form of 1234 TEMP25. Regulation
can be canceled by SMS with command 1234 OFF or pressing the button BTN.
7. GSM-R5-Tx factory setting is possible to restore by sending SMS message
1234 !FACTORY. If you made a backup configuration of SeaConfigurator settings
(Settings tab -> Files button -> File option), you can restore your settings from this
backup (Settings tab -> Files button -> File option).
8. The names of the inputs, outputs (their states) and the command names can be
modified according to your ideas using the SeaConfigurator configuration
software. This configuration program can be downloaded free of charge from
www.seapraha.cz (enter the word „Configurator“ in the search) and install it on
your PC.

6.2 Recommended connection
Before inserting the SIM card into the GSM-R5-Tx device, it is
necessary to turn off setting of the “PIN code”!
Insert the active SIM card (= at least one call was made) to any mobile phone
and turn off the requirement of setting the PIN. On most mobile telephones,
this option can be found in menu “Setting the telephone protection” or “Setup
-> Security -> PIN control”.

6.4 SIM card reader and pushbutton
Insert SIM card into GSM-R5-Tx (see the picture). Proper insertion is indicated by
mechanical clicking noise. Push and release to remove the SIM card from GSM-R5-Tx.
Press shortly the button to change the output
Y2(OUT) status. Press the button for 5 seconds (or
longer) to switch the GSM-R5-Tx to sleep mode
(this feature is available when supplied from
battery only). Sleep mode is canceled when GSM-
R5-Tx is again supplied from power supply. When
the main power supply is connected, press the
button for 5 seconds (or longer) and the unit will
restart.
Mini USB connector is used for a configuration with SeaConfigurator.
Antenna is connected using SMA connector. GSM-R2-T is equipped with SMA female
connector. It means that antenna has to be equipped with SMA male connector.
Impedance is 50 Ω.
6.5 Accumulator
GSM-R5-Tx is equipped with a 3.7 V stand-by Li-Ion accumulator. After power failure,
the device is able to operate in normal mode for about a day (the duration depends on
how much it is used).The accumulator can be used for supply of inputs –see
Recommended connection.
7. Configuration
GSM-R5-Tx is configured with SeaConfigurator either via the USB connector (miniUSB
cable) or through the GPRS connection. This configuration program can be downloaded
for free from http://www.seapraha.cz (search for „Configurator“) and install it on your
PC.
GSM-R5-Tx is shipped with a factory configuration that meets the most common
requirements, so it is possible to use the device even without SeaConfigurator. Simply
send the first SMS from the main user's phone number under the “First time startup”
chapter.
Some parameters be changed via SMS, see chapter „Command List“.
8. GSM-R5-Tx Control
8.1 Control output by “ringing”
GSM-R5-Tx is set by the manufacturer to switch ON an output Y2(OUT) for 4 seconds
based on ringing from any phone number. This pulse is useful e.g. for opening of an
entry gate. Test this function by a call to GSM-R5-Tx from your mobile phone (it’s
important to send a valid command SMS to GSM-R5-Tx from your mobile phone if have
inserted a “new” SIM card to GSM-R5-Tx first).
GSM-R5-Tx rejects a call and then immediately generates a pulse on an output Y2(OUT).
8.2 Remote control via SMS
GSM-R5-Tx is controlled via SMS of the GMS network. Text SMS are in form:
PASSWORD space COMMAND space COMMAND
Commands are separated by a space and are not case sensitive.
Password
Password is the main security element in control of GSM relay
5
. SMS with commands
will be accepted from anyone who knows the password. The password is a string of
digits (it can be any length from 1 to 20), Which the SMS message must contain, or
else it’s ignored. Because the text before the password is ignored, SMS messages can
also be sent from the SMS gateways. We recommend changing the password to
something different. Password can be changed either through SeaConfigurator or with
SMS message.
Default password is:
1234
Command
This part of the message defines the desired action of the device. Multiple commands
separated by a space can be inserted into one SMS message.
The command can consist of multiple parts. For example, when it comes to output, it
consists of its name „Y2“ and an action (e.g. ON, OFF, etc.). If the naming of the output
is not specified, the output with the lowest sequence number is used (for the GSM
relay5it is the socket). The ON and Y2 ON commands are therefore equivalent.
In addition, a parameter (e.g. pulse length, required temperature, etc.) may be given
behind the command. There must be space between the command and its parameter.
Most used commands (more in chapter “List of commands“)
Examples:
1234 ON an appliance connected to output Y2(OUT) will be switched on
1234 Y2 ON an appliance connected to output Y2(OUT) will be switched on
1234 OFF an appliance connected to output Y2(OUT) will be switched off
1234 TEMP 5 set and activate the temperature regulator function to +5 °C
1234 PULSE 3600 output Y2(OUT) will be switched ON and than after 1 hour will
be switched OFF (Note: if an output is already switched on, it will
be just switched off after 1 hour)
Confirmation
If a command message contains a valid password (access code) the GSM-R5-Tx sends
back a confirmation message which informs if a command was accepted. If you don’t
want a confirmation message (e. g. when sending a command SMS from the Internet
GSM gates) add a command “NOBACK”.
Example:
1234 Y2 ON NOBACK GSM-R5-Tx will switch on an appliance connected to
output Y2(OUT) but no confirmation message will be sent back.
8.3 Status message
The status message is send whenever the command message contains a valid password.
Example: 1234 Y2 ZAP
If it is not disabled the STATE message will be appended to the message about
execution. State message contains following information:
Status message example
Explanation
GSM-R5-Tx: Y2 ON SUCCESS
Command confirmation: to switch ON Y2(OUT)
Power=Powered
State of power(from battery or from source).
Temp=28’C
Actual temperature on a temp. sensor T1 is 28°C.
OUT=on
State of output Y2(OUT) is ON.
IN=on
State of input X3(IN) is ON.
Sig=58%
GSM signal level is 58%.
Note: If any input or output is disabled (by SMS or by SeaConfigurator), it won’t be
mentioned in STATE message.
8.4 Macros
Built-in macros with variables
You can use macros listed in the macro list in the event text. These macros are used
when you want to create your own status message. In this case, be sure to cancel the
„state message reply“ option in the „General Settings“ section.
Examples:
SMS with text: „Temperature is low, [Y2].“ Will be sent as „Temperature is low,
Y2=ZAP.“
SMS with text „output is ON([A1N] is [A1V]).“ Will be sent as „output is ON
(TEMPERATURE is 18,1 °C).“, where „input name“ A1 is TEMPERATURE and „units“ are
in °C.
Macros in incoming SMS
If you need to simplify a regular repeating command or a summary of commands
(including even the parameters), create a macro. For example, create a macro: „FIRE“
with text „Y2 TEMP 25“. If you then send an SMS with the text „FIRE“, output Y2 (OUT)
will be regulated by the temp. Sensors at 25 ° C.
Macros in sent SMS
For example, you can define the macro „N1“ with the text „My Station is Best in the
World“ to help you work on creating text in sent SMS. Then just use the text „[N1]“ in
the outgoing SMS.

11. Examples
The following examples describe the most widely used methods of using the GSM-R2-
T. All examples are based on the "default" parameter settings on the SIM card (see
Chapter 6)
11.1 Remote control of heating on a cottage
The electrical appliance is connected to output OUT of GSM-R2-T using a contactor.
Following SMS message will switch ON the electric power to a heating:
1234 ON
Following SMS message will switch OFF the electric power to a heating:
1234 OFF
The proper function depends on the following parameters on a SIM card:
xCode 1234
xRegOut 0
Note: If the password was changed from the „default” factory 1234 to another (e.g.
6543), the SMS has to be 6543 on (6543 off).
11.2 Remote control of heating regulation on a
cottage
The electrical appliance is connected to output OUT of GSM-R2-T using a contactor.
SMS message in the following format sets the requested temperature to 25 ° C for
temperature regulator and activates the function “regulator”:
1234 temp25
The proper function depends on the following parameters on a SIM card:
The default factory setting is not necessary to change:
xCode 1234
xReg 1
xRegHyst 1
xRegIn 1
xRegOut 0
11.3 Entry gate opening by phone call from a
mobile phone (without confirmation)
The gate control is connected to output OUT of GSM-R2-T. After the first ringing from
the phone number from which was sent the first valid SMS command GSM-R2-T rejects
a call and the entrance gate will open. The next call will close the entrance gate.
Correct function is affected by following parameters on the SIM card (items in the phone
book); default parameters need not to be changed:
xIo0pulseLen 4 (note.: o0 = "ó" and "zero")
xRemDout 0
xRemCall 1
xRemConfirm 0
xMaster [phone]
If you need to control the entry gate using different phone numbers, add these numbers
on SIM card:
xRUser1 [phone]
xRUserPeter [phone]
Note. It’s possible to append characters to „xRUser“ for better identification of a user’s
phone number.
11.4 Entry gate opening by call from a mobile
phone (with confirmation)
After the first ringing from the phone number which is in the list of users (xRUser. ..) of
the GSM-R2-T, it rejects a call and calls back. When the calling user rejects the call
within 29 seconds, the entrance gate will open.
The setting of parameters on a SIM card is the same as it the previous chapter (8.3),
except xRemConfirm parameter which must be set to "1":
xRemConfirm 1
12. Event SMS Messages
Whenever any event appears on the GSM-R2-T input or output for longer than minimum
specified time, the GSM-R2-T sends an SMS about this event. To increase the probability
the user will read the SMS it can be followed by a voice call from GSM-R2-T. See the
xe[...+...+.....] parameters.
If you answer the phone call you will hear a voice message in a form of DTMF signals.
13. Examples of event messages
The following examples describe the most common examples of what can GSM-R2-T to
send to you. All the examples are based on the "default" parameter settings on the SIM
card (see Chapter 6).
13.1 SMS message based on input event (an input
IN1 is activated by voltage)
By applying a voltage to the input IN1 (= input is activated) is sent the following SMS
text:
GSM R2 T: In1 ALARM!
out=on
in1=on
Sig=64%
Temp=ERROR
As a phone number is used the phone number from which was sent the first valid SMS
(in this example is used phone number [phone]).
Correct function is affected by following parameters on the SIM card (items in the phone
book); default parameters, which need not to be changed:
xMaster [phone]
If you need to send the SMS message to other phone numbers, you must add them to
the SIM card phone book:
xRUser1 [phone]
xRUserPetr [phone]
13.2 Call when the voltage disappears from input
IN1
By disconnecting the voltage from the input IN1 (= input is deactivated) the phone
number from which was sent the first valid SMS ([phone] in this example) is
called.
Correct function is affected by following parameters on the SIM card (items in the phone
book); default parameters, which need not to be changed:
xeI1+HL+CALL [phone]
13.3 SMS when the temperature drops
If you want to receive SMS when the temperature drops below +5 ° C, it is necessary
to set these parameters on the SIM card:
xeA1+HL+SMS [phone]
xAIn1Level 10
xAIn1Hyst 5
Level (Level) is set to 10 ° C, the hysteresis (Hyst) at 5 ° C. SMS is sent when the
temperature drops below +5 ° C (+10 ° C - 5 ° C). The SMS is re-sent after the
temperature rose above +15 ° C (10 ° C + 5 ° C) and then falls below +5 ° C again.
14. Advanced functions
14.1 Automatic Voice Call
Automatic voice call enables to verify the ability of the GSM-R2-T to make a voice call in
case of any event (i.e., functionality, the credit, the GSM signal etc.).
In the following example the GSM-R2-T will call you between 9:00 and 18:00 of a local
time. It means you will not be woken up in the middle of night. If you will not answer
the call, the GSM-R2-T will repeat the call after 2 minutes again.
Example of parameters on a SIM card:
xAutoCall = [phone] … (= call the phone number [phone])
xAutoCallInt = 1 … (= call every month)
xAutoCallIntFrom = 9 … (= call between 9 am
xAutoCallIntTo = 18 and 6 pm)
Format of xAutoCallInt parameter is: 1 = 1 month, #2 = 2 days, *3 = hours, 1#2*3
= 1 month 2 days 3 hours. The time period between calls starts whenever new value of
the parameter is set (it happens when the SIM card is inserted into GSM-R2-T and the
power supply is set on).
14.2 Automatic SMS message
This function is useful for reporting “I am alive” and inputs and outputs status via SMS
messages. You can set a phone number to send automatic SMS message (xAutoSms),
time period between two SMS messages (xAutoSmsInt), begin (xAutoSmsIntFrom)
and end (xAutoSmsIntTo) time, when automatic SMS message is allowed to be sent.

GSM-R5-Tx_User_Manual_EN_v1-16.docx
Page # 5 of 6
Example of parameters on a SIM card:
GSM-R2-T sends SMS message every day between 18:00 and 21:00.
xAutoSms = [phone] … (= send SMS toe phone number [phone])
xAutoSmsInt = #1 … (= send an SMS every day)
xAutoSmsIntFrom = 18 … (= send an SMS between 6 pm
xAutoSmsIntTo = 21 and 9 pm)
Format of xAutoSmsInt parameter is: 1 = 1 month, #2 = 2 days, *3 = hours, 1#2*3
= 1 month 2 days 3 hours. The time period between SMS starts whenever new value of
the parameter is set (it happens when the SIM card is inserted into GSM-R2-T and the
power supply is set on).
After saving parameters on the SIM card the GSM-R2-T sends an SMS with the following
text:
GSM R2 T: Device OK. .... followed by status information.
14.3 Limit the number of alarm SMS (max. 1 SMS
every 3 days)
Example of parameters on a SIM card:
xLimit 1
xLimitCount 1
xLimitTime 3
14.4 Setup credit limit to 70 CZK
When credit drops below 70 CZK, GSM-R2-T will send warning SMS message.
Example of parameters on a SIM card:
xCredit 1
xCreditLimit 70
xEvent8004 *) [phone]
*) These parameters must be created by user in the phone book on SIM card.
14.5 Redirection of SMS without valid password
Master (parameter xMaster) can get all messages sent to the GSM-R2-T without valid
password. This function helps to watch all unauthorized attempts to control the GSM-
R2-T. Every SMS message without valid password is forwarded to phone number
depending on the xMaster parameter, in case this function is switched on. For example
credit warning message from provider.
Use parameter xRedirect to switch this function on or off (value 1 = function on, value
0 = function off).
