repairing the unit. The use of differing
spare parts can cause serious material loss
or personal injury.
Proper Use
The device is designed for the remote
switching of devices via the GSM network as
well as the remote retrieval of status
information of the inputs and the generation of
SMS messages after status has changed at the
inputs. A different use apart from the one
described above is not allowed.
The STD32 is a telemetry module which is
easy to install and simple to use.
With the STD32 you can control two relays and
monitor the status of two digital inputs with a
common mobile phone.
Apart from the STD32 you only need a valid
SIM Card of any network provider (GSM 900 /
1800 MHz). Typical fields of application are the
opening of (garage) doors, switching on and off
light and alarm devices as well as generating
alarm messages (SMS) or the retrieval of
information from door sensors, movement
sensors or level sensors etc.
pairs (Relay1, Relay2) are outputs (switches)
of the 2 relays of the STD32.

pairs of screw terminals. Two pairs (In1, In2)
are inputs to two optocouplers. The other two
open the SIM card holder move it sideward and
flip it open; insert the card (mind the
orientation) and close it again. To fix it move
the top sideward in opposite direction.
a) Preparation
You need an activated SIM card of a GSM
network provider. The PIN of this card has to
be set to „0000“. To change the PIN you can
use a common mobile phone. The instructions
how to change the PIN are described in the
manual of your mobile phone.
Connect the antenna, if not already done.
Now connect the power supply. Shortly after
that the GSM LED will shine constantly. Now
the STD32 will automatically try to connect to
the GSM network. As soon as this is done, the
GSM LED will be flashing once every 2
If you use a SIM card with a PIN different
from „0000“ in the STD32, the STD32 will
use a „wrong“ PIN after every restart. After
the third trial your SIM card will be blocked.
In this case you need to use the „SuperPIN“ or „PUK“ to assign a new PIN to your
card. Please look into the user guide of your
mobile phone. There you find how to use
the PUK to de-block the SIM card.
b) Configuration call
Wait until the GSM LED is flashing. Now take
the mobile phone with which you want to
control the STD32 and call the phone number
of the SIM card which is inside the STD32. The
STD32 will accept the call and cancel it a few
seconds later. You will hear nothing during the
established call. With this call the STD32 is
configured to the mobile phone. From now on
Before connecting the supply voltage to the
STD32 please insert the SIM card into the SIM
card holder on the backside of the STD32: To
that the STD32 sends a reply SMS with the
actual status of the inputs and outputs.
the STD32 can only be operated by this mobile
phone(or this SIM card in another phone).
If you want to use another mobile phone with a
different phone number with your STD32 you
have to set it back to the factory settings before
you can make a new configuration call (see
chapter “configuration SMS”).
When the digital input IN1 is activated for
one second, the STD32 sends a SMS with
the text „EVENT ALARM1“ to the
preconfigured phone number
When the digital input IN2 is activated for
one second, the STD32 sends a SMS with
the text „EVENT ALARM2“ to the
preconfigured phone number.
After having configured the STD32 the
following functions are available (see chapter
d) Switching per SMS
c) Basic functions
The STD32 is automatically sending an
SMS with the text „START-UP ALARM“ to
the configured phone number after the
supply voltage is connected.
Before sending SMS messages to the
STD32 please read “SMS Commands” in
chapter „Operation“.
After the STD32 has received a SMS with
the text „O1ON“ from the configured mobile
phone, the relay 1 switches for one second.
With the SMS „O2ON“ relay 2 switches for
one second.
When you call the STD32 from the
configured mobile phone the relay 1
switches for one second. Immediately after
„O1OFF“ permanently switches off relay 1.
Relay 2 is reacting accordingly to SMS
messages with „O2ON“ and „O2OFF“. In
case the switching time is not set to 0
„O2OFF“) have the same effect as
described under d).
If the switching time has been set to 0 by a
configuration SMS the relays switch
permanently (see e)).
e) Configuration SMS
Before sending SMS messages to the
Commands” in chapter „Operation“.
A SMS with the text „O1:xxx“oder
„O2:xxx“(xxx = seconds) configures the
switching time of the relays. The STD32
saves these settings so that they are still
available after the supply voltage has been
If the switching time has been set to 0 by a
configuration SMS the corresponding relay
switches permanently at every call. If the
relay has been active before it will
afterwards be inactive and vice versa.
In this case a SMS with the text „O1ON“
from the configured mobile phone switches
the relay 1 permanently on. A SMS with
With a SMS with the text „I1:xxx“ or „I2:xxx“
(xxx = seconds) you can configure the time
the inputs have to be activated before the
STD32 sends out an alarm SMS.
A SMS with the text „V1:x“ or „V2:x“ (x = 1
or 0) can change the polarity of the inputs.
If x=1 an alarm SMS will be sent in case
the input has not been activated for the
configured time.
You can activate or deactivate the Start up

After successful configuration (see chapter
„Startup“) please call the phone number of the
SIM card which is inside the STD32. Take care
that your mobile phone is transmitting the
phone number (to check that you can call
another mobile phone; your phone number or
name must be visible on the display then) Now
the relay should switch for a certain time
according to the configuration. The status LED
for relay 1 is shining during that.

The last digits of the IMEI are the password to
your device and should be kept confidential.
The IMEI cannot be changed!
b) Generate an alarm SMS
Connect 12V (factory setting) to an input for
one second and mind the polarity. An alarm
SMS will be sent to your mobile phone.
All Commands (except R: and ST?) must end
with a full stop (.)!
c) Send SMS Commands
All Commands can be sent in one SMS; each
command has to separated from the next by a
full stop.
To protect your STD32 against unauthorized
use every SMS has to start with the last 4 digits
of the IMEI number. YOUR IMEI is printed on
the GSM-engine of your STD32.
The parameters for the seconds can have 1-3
digits. Valid parameters are e.g. 1 or 90 or 999.
Please observe the difference between the
figure 0 and the letter O! (O1ON. contains
twice the letter O, V1:0. contains once the
figure 0)
