GSM-R2-T
1.
Introduction
GSM-R2-T is a device designed
for DIN rail mounting
. GSM-R2-T 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-R2-T 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-R2-T has also one logical
input. This input can be activated by external voltage 8 to 30V
DC/AC
. The GSM-R2-T 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-R2-
T. Analog input is designed for connection of temperature sensor and can be used in
“temperature regulation” function of GSM-R2-T which can control connected heating
system to maintain the preset temperature. The temperature of a temperature sensor
can be readout via SMS.

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. See the chapter 5.4 for
details.
3.
Now it’s possible to connect GSM antenna and power supply to GSM-R2-T. Ca
1 minute
later the blue LED diode
GSM
will start flashing with a period of 3 sec.
4.
For the first tests of GSM-R2-T the connection of an input and output is not
necessary.
5.
To make the first test of the GSM-R2-T, use your mobile telephone 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-R2-T. This will switch on
the plugged appliance. GSM-R2-T automatically sends a confirmation message on
performing the operation.
To change the password 1234, insert the SIM card into any mobile telephone and in the phonebook
on the SIM card in field “Names” for name xCode change the telephone number 1234 to a number
you select. The device reacts to the SMS text message from any telephone as long as the access
password matches. The very first one (the sender of the message) will be remembered as master
and will receive message about events on GSM-R2-T. This user can also switch some output by
“ringing“ on the device.
6.
Try “
ringing
” on device. You can make pulse on OUT for ca. 4 seconds by calling
on GSM-R2-T (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.
7.
Try regulation. You can send SMS in form of 1234 TEMP25 to command device to
maintain temperature 25 °C depending on the temperature sensor T1. Range of
regulation is between 0 °C and +55 °C. Regulation can be canceled by SMS with
command 1234 OFF or by ringing (no confirmation is sent back in case of
ringing).

Recommended connection
Before inserting the SIM card into the GSM-R2-T 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”.
