SIM card reader and pushbutton
Insert SIM card into GSM-R2-T (see the picture). Proper
insertion is indicated by mechanical clicking noise. Push and
release to remove the SIM card from GSM-R2-T.
Press shortly the button to change the output “OUT” status.
Press the button for 5 seconds (or longer) to switch the
GSM-R2-T to sleep mode (this feature is available when
supplied from battery only). Sleep mode is canceled when
GSM-R2-T is supplied from power supply.
5.5
Antenna
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.
Configuration
Configuration parameters of GSM-R2-T are stored on a SIM card phone book. The
phone book contains a pairs <name, number>. After Power On of GSM-R2-T this
phone book is searched for the names in a following table: (
Names are not case
sensitive
, xcode = xCODE). If any parameter is not present, the default value for this
parameter will be used.
All phone numbers must be in an international form: + (Country code) (phone
number) e.g. +420777777497.
Tip: Use your mobile phone to make changes in parameters of GSM-R2-T: Insert the
SIM card from the GSM-R2-T into your mobile phone. Make necessary changes of
parameters in a phone book of a SIM card and put the SIM card back into GSM-R2-T
again.
The first person who sends valid SMS to GSM-R2-T with a “clear” SIM card inserted,
became a main user (master) of the device.
In all following examples we suppose the GSM-R2-T is already fully functioning with a
SIM card. (See the chapter
Installation
).

GSM-R2-T Control
7.1
Control output by “ringing”
GSM-R2-T is set by the manufacturer to switch ON an output 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-R2-T from your mobile phone (it’s important
to send a valid command SMS to GSM-R2-T from your mobile phone if have inserted a
“new” SIM card to GSM-R2-T first).
GSM-R2-T rejects a call and then immediately generates a pulse on an output OUT.
The number of users is max. 200.
7.2
Remote control via SMS
GSM-R2-T is controlled via SMS of the GMS network. Text SMS are in form:
<PASSWORD> <COMMAND> [<RETURN COMMAND >]
Example
1234 ON
… GSM-R2-T will switch ON an appliance connected to output
“OUT”. This action will be confirmed by an SMS.
1234 OFF NOBACK
… GSM-R2-T will switch OFF an appliance connected to output
“OUT”. Confirmation SMS message will not be sent back.
Password
Password is a main security item for GSM-R2-T. Command SMS are accepted from any
phone number. It means anybody who knows the password and the phone number
can control the GSM-R2-T. The password is a string of digits (1 to approx. 20) which
must be on the beginning of any command SMS. Otherwise the SMS will be ignored. A
text before the password is automatically ignored. It is useful when command SMS are
sent from Internet GSM gates.
Factory setting of a password (see chapter List of All Parameters, parameter
xCode
)
is:
1234
Command
This part of a message specifies a requested action. See the following table for
available commands. GSM-R2-T is not a case sensitive. It’s possible to use more
commands in one SMS. Commands are separated by a space.
Command
Parameter
Meaning
ON
-
Output “OUT” will be switched ON
OFF
-
Output “OUT” will be switched OFF
PULSE
-
Output “OUT” will be switched ON for 4 seconds
(= 4sec. pulse will be generated)
TEMP
0 to 55
Requested temperature setting (value in °C). An
output specified by xRegOut parameter will be
controlled to maintain this temperature.
STATE
-
Request of status SMS (state of inputs, outputs,
signal quality and credit).
Examples:
1234 ON
… an appliance connected to “OUT” will be switched on
1234 OFF
… an appliance connected to “OUT” will be switched off
1234 PULSE
… output “OUT” will be switched ON for 4 seconds (= 4 sec.
pulse will be generated) (Note: if an output is already switched
on, it will be just switched off after 4 seconds)
1234 TEMP5
… GSM-R2-T will set and activate the temperature regulator
function to +5 °C
Confirmation
If a
command message
contains a valid password (access code) the GSM-R2-T sends
back a confirmation message which informs if a command was accepted (see chapter
Status SMS). If you don’t want a confirmation message (e. g. when sending a
command SMS from the Internet GSM gates) add a command “NOBACK”.
Command
Meaning
NOBACK, NEZPET
No confirmation SMS will be sent
Example:
1234 ON NOBACK
… GSM-R2-T will switch on an appliance connected to output
“OUT”, but no confirmation message will be sent back
7.3
Status message
The status message is send whenever the command message contains a valid
password. The typical example of status message:
Status message example
Explanation
GSM R2 T: ON SUCCESS
Command confirmation: to switch OUT ON
out=on
Output OUT status
in=ok
Input IN1 status
Sig=58%
GSM signal level
Temp=28’C
Actual temperature on a temperature sensor T1
Credit=243.15
Credit on a prepaid SIM card
Note: Status message has maximum length of 160 characters. (Characters over the
length of 160 will be lost).
7.4
Control via application for OS android
For control and monitoring of GSM-R2-T can be used the app to Android OS call
“
SeaControl
”, which can be download for free and without any restriction. For details
and to download an application, go to
www.seapraha.cz
, where fill in the field
“SEARCH” the text “GSM-CONTROL”.
This application communicates with the GSM-R 2-T through SMS messages.

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)
8.1
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:
LED GSM
SIM card reader
antenna SMA (f)
