2 Background Information

2.1 GSM-Network in general

The GSM Network (Global System for Mobile Communications) is a standard for all-digital
mobile phone networks. GSM has been created to provide a mobile telephone system offering
the users Europe wide mobility and voice services compatible with ISDN or analog services.

Originally GSM has been designed for voice calls, the transmission of text messages (SMS) and
the transmission of data with a constant data speed. With the success of the internet an
evolution of GSM startet. The GSM network was expanded to offer packet oriented data
transmission (e.g. via GPRS) while keeping all other features and being fully downwards
compatible.

2.2 GPRS

GPRS (General Packet Radio Service) is a packet oriented transmission service which is used in
the mobile networks and which is supported by almost all network providers.

With GPRS you only have a virtually existing permanent connection to the other party. Only
when you really transmit data will the channel will be used, otherwise it is free for other users.
This means that no channel will be reserved permanently for a user (as it is with a GSM voice
call). Therefore the GPRS-bills depend more on the actual data volume transmitted than on the
connect time.

If the device is booked into the GPRS-Net it will automatically be assigned an IP-Address and
can exchange data with any server accessible via the internet,

Before you can use the GPRS-Interface the SIM-Card must be activated for GPRS. To order this
functionality please talk to your mobile network provider.

2.3 Quadband Frequencies

When a device is “quadband” it means that it uses the four major GSM frequencies and that it
is compatible with most GSM networks worldwide.

These four frequencies are 850 MHz and 1900 MHz (on the American continent) and 900 MHz
and 1800 MHz, which are used in almost all other countries worldwide (Europe and Asia).

In contrast to a triband mobile phone which only supports 900/1800 and 1900 or 850/1800
and 1900 a quadband device can be used in almost every GSM network worldwide.

2.4 E-Mail via SMTP

SMTP (Simple Mail Transfer Protocol) is a method used to send e-mails over the internet. The
handling will be done by a mail programme, which is running in this case on the STD35 and
which supports SMTP. For the user this process is invisible. This programme establishes a
connection to a SMTP server which will transport the e-mail to the given e-mail address with
the help of further SMTP servers if necessary.

To be able to use this service you must have an e-mail account with a mail provider (e.g. AOL
or Yahoo) and the following settings have to be made which are different for every mail
provider

 Name of the SMTP Server (e.g. smtp.mailprovider.com or 192.168.234.12)
 User name to register to the SMTP Server
 Password to register to the SMTP Server

The device comes pre configured to use the free CEP email server. If the user
wishes to use there own email service it is important to note it must support plain
text authentification and Emails with no SSL-Encyption

To see which settings have to be used on the STD35 to be able to take advantage of this
service please read chapter 8.

3 Operating Conditions

Operate the STD35 only with a supply voltage between 7-32V DC and have in mind the
polarity! (see picture1) Use a stabilized power supply with minimum 1A output current. (We
recommend using only the original CEP power supply). If you use a mains adapter for power
supply it has to conform to the VDE regulations.

 Loads connected to the device are not allowed to exceed 30 W per relay.
 The maximum output voltage is 30 V AC/DC
 The maximum switching power per relay is 1 A
 When installing the device make sure that the supply cable has a sufficient diameter
 During operation the temperature has to be between -30° and 75° Celsius.
 Protect the PCB of the device from humidity, spray water and heat.
 In case of condensation allow a period of about 2 hours for acclimatisation.
 Do not operate the device in areas where inflammable gas, vapours, or dust are or could be

present.

 Do not expose the device to heavy vibrations.
 The unit may only be repaired by a specialist.
 Only original parts have to be used when repairing the unit. The use of differing spare parts

can cause serious material loss or personal injury.

 No special operation position of the device has to be observed.

4 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 or e­mails after status has changed at the inputs. A different utilization of the device other than the
one described above is not allowed.

5 Introduction

The STD35 is a telemetry module which is easy to install and simple to use. It can be
configured using any GSM mobile phone, SMS capable software, or the CEP STD35
configuration tool (sold separately).

With the STD35 you can control five relays and monitor the status of three digital and two
analog inputs with one or several common mobile phones.

Apart from the STD35 you only need a valid SIM Card of any network provider (GSM850 / 900
/ 1800 or 1900 MHz)

While using prepaid SIM-cards one shall always keep aware of the amount of remaining credit
left on the card, so that in case of alarms a message can be sent.

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

e-mail)

 the retrieval of information from door sensors, movement sensors or level sensors
 etc.

You can for example open your garage door with a call or get a message (via SMS or e-mail) in
case your house alarm system gets triggered. In connection with the CEP camera you can get
a photo via e-mail when a movement sensor connected to the STD35 detects movement.

Connectors

As described in figure 1 the STD 35 has 3 Green Screw terminals. One connector is for the 5
inputs (3 digital and 2 analog/digital). Another connector is for the 5 outputs which are all
driven by relays. And the third screw terminal connector is for the power supply.

On the right side of the diagram an additional accessory interface connector is shown. This
connector is for use with the optional CMOS camera or the CEP Configuration tool.

ANT: connect the GSM antenna with FME-female connector here.

Please observe the maximum output voltage of the relays and the maximum input voltage of
the inputs! In chapter 3 “Operating conditions” you will find further information on this.

10

LED Signals

The STD35 has several LEDs which can be used to determine the current state of the device.

There are two power LEDs. A red power led that is illuminated when charging is taking place,
when not charging (battery full, or no charger is connected) it is off. A green power led saying
that is illuminated whenever the device is on. Normally this led reflects the state of the power
switch.

There is also a Yellow “COM” led it gives information regarding the current GSM status:

- stable in indicates the device is not currently booked into the GSM network

- blinking once every 2 seconds indicates the device is booked into the GSM network as
normal.

There are also separate red and green status LEDs. Under normal operating conditions these
two LEDs are not illuminated. However status red and status green can toggle if there is no
configuration yet (when in factory default state).

The status LEDs and GSM led (COM) will blink twice if no simcard (or an invalid simcard) has
been inserted. The status LEDs and GSM led (COM) will blink three times if the SIM PIN is
different than "0000" or "2468".

Switch:

There is also a small power switch between the power connector and the LEDs. This switch is
used to tum the device on and off.

6 Quick start up

In the following section it is described step by step what you have to do to begin using the
STD35 without extensive setup.

6.1 General preparations

You need an activated SIM card of a GSM network provider. The PIN of this card has to be set
to “0000” (4 times zero).

Alternatively you could use the PIN “2468”. 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.

If you use a SIM card with a PIN different from “0000” or “2468” in the STD35, the
STD35 will use a “wrong” PIN. After the second attempt to power up the device
your SIM card will be blocked. In this case you need to use the “Super-PIN” 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.

Should you wish to use a SIM card which does not require a PIN, this is also possible and the
STD35 recognizes this and will behave accordingly.

In the following we will refer to the “master mobile” as the mobile telephone which you want
to use to switch the outputs and to configure the STD35 via calls.

To be able to administer the STD35 with your master mobile it is necessary that the “incognito”
or “private call” function of the mobile is deactivated. This means the master mobile has to
transmit the mobile telephone number with every call. To change the settings please refer to
the user guide of your mobile telephone.

To test the setting you can call a different mobile phone; there your phone number or name
should be displayed.

6.2 Hardware preparations

Before connecting the supply voltage and switching on the STD35 please insert the SIM card
into the SIM card holder on the PCB of the STD35: To open the SIM card holder move it
sideways and flip it open; insert the card (mind the proper orientation of the card) and close it
again. To lock it in place move the top sideways in the opposite direction.

Now please connect the GSM antenna which is part of the delivery to the proper antenna
connector on the STD35 board.

After that connect the power supply and switch the device on.
Please always observe the polarity (see picture 1) and that you have a proper power supply.

12

6.3 Configuration Call

After having connected the power supply and turning the device on the green power LED will
be illuminate (system start). Shortly after that the GSM LED will be activated. Now the STD35
will automatically try to connect to the GSM network. As soon as this is done, the GSM LED will
be flashing once every 2 seconds.

As soon as the red and green system LED are toggling the STD35 is ready and waiting for the
configuration.

Now call with master mobile the phone number of the SIM card which is inside the STD35. The
STD35 will accept the call and cancel it a few seconds later. During this call, a four digit DTMF
sequence is sent to the caller and you will hear them on your mobile phone.

With this call the STD35 is configured to the master mobile.

NOTE: when calling with the master phone it is necessary caller ID is not blocked, or
configuration call will not work correctly!

Pay attention:

As long as the STD35 still has the factory defaults it shows this by the toggling the red and
green system LEDs. From this moment on you have three minutes to configure the STD35 with
the configuration call.

After 3 minutes (without configuration call done in between) the device switches off. If you
switch it on again afterwards the STD35 is again expecting the configuration.

In case the STD35 will be disconnected from the power supply for longer than 120 seconds
(e.g. by a power failure) after a successful configuration it will automatically send a SMS/E-mail
with the text “START-UP ALARM” to the preconfigured telephone number as soon as the power
supply is established again.

6.4 Quick configuration check

To check whether the configuration was successful you can now make the following quick
configuration check.

Take your master mobile and call the telephone number of the SIM-Card inside the STD35.
This call should be cancelled by the STD35 and the Relay 1 should switch for one second.

Now the basic configuration is done which means that all future events will be sent to the
master mobile and that Relay 1 can be switched from that mobile phone.

To use the additional functions of the STD35 please continue reading chapter 7 “SMS
commands”

7 SMS Commands

In order to configure the device, request information from it, or trigger certain actions special
commands are used. All the commands are designed to be easy to enter even when using a
standard phone to send them via SMS. This chapter of the manual describes all the commands
the device will understand and how to use them.

With the optional CEP configuration tool available for the STD35, you can make all the settings
below from the comfort of your PC.

7.2 Variable substitution

In order to display some information in event texts it is possible to include in event text strings

“variables”. When a variable is included in an event text string, the variable is replaced by the

value it is intended to represent in the string that is sent to the user, either via SMS or email.

The following table describes the available variables and the data they represent

• $CALID$

last incoming CLIP number

• $CNT$

X/Y (where X is sent SMS counter and Y is sent EMAIL counter)

• $IN1$, $IN2$, $IN3$, $IN4$, $IN5$

current input value as a string (LOW or HIGH)

• $OUT1$, $OUT2$, $OUT3$, $OUT4$, $OUT5$

current relay value as a string (ON or OFF)

• $IN1T$, $IN2T$, $IN3T$, $IN4T$, $IN5T$

current input value as a integer (0 or 1)

• $OUT1T$, $OUT2T$, $OUT3T$, $OUT4T$, $OUT5T$

current relay value as a integer (0 or 1)

• $VBATM$

battery voltage in milivolts (integer)

• $VBAT$

battery voltage in volts (float)

• $VMAINSM$

mains voltage in milivolts (integer)

• $VMAINS$

mains voltage in volts (float)

• $VIN4M$

input 4 voltage in milivolts (integer)

• $VIN4$

input 4 voltage in volts (float)

• $VIN5M$

input 5 voltage in milivolts (integer)

• $VIN5$

input 5 voltage in volts (float)

Example: E1:battery=$VBAT$. This will send a text message that returns to the configured
number the current battery voltage in the message.

7.3 Send SMS Commands

By sending a SMS to the STD35 you can switch the outputs or make individual configuration
settings.

Those SMS have the following format which is described below:

In order to avoid unauthorized usage, every configuration command to the STD35 must start
with a 4-digit password.

The last four digits of the IMEI being the password for your device must always be kept a
secret. In this example the keyword is “4244”.

You find your Devices IMEI printed on a sticker on the back of the housing.

The IMEI cannot be changed! Although the password can be changed if needed for security
purposes, you should keep in mind that every command – including setting back to factory
settings – requires the knowledge of the password.

All commands (except R: and ST?) must end with a full stop “.”!

If you need a full stop "." in a parameter as it is for example in an e-mail address or in some
APN-settings, the complete parameter has to be put into inverted commas (“...”) (e.g.
"[e-mail]"), as otherwise the "." would be seen as the end of the command.

All commands can be sent in one SMS; each command has to be separated from the next by a
full stop (see examples).

The parameters for the seconds e.g. command “O1:xxxxx.” can have 1-5 digits. Valid
parameters are e.g. 1 (for 1 second), 90 (for 90 seconds) or 99999 for (99999 seconds). No
leading “zeros” have to be added. Example: “O1:110” stands for 110 seconds.

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)

7.4 Explanation of the commands

Switching outputs via SMS

 After the STD35 has received a SMS with the text “O1ON.” (Output 1 ON) from the

configured mobile phone, the relay 1 switches for one second. With the SMS “O2ON.” relay
2 switches for one second.

 To get feedback of the actual status of the inputs and outputs just send a SMS with “ST?”

Configuration-SMS (attention 4-digit keyword required!)

 The SMS “R:” is sets the STD35 back to the factory settings. Please note that this SMS can

be sent from any mobile phone as long as the 4-digit keyword is known. This ensures that
the STD35 can still be used even if the original master mobile (phone number) is no longer
available.

 You can activate or deactivate the Start-up SMS (START-UP ALARM) with the SMS “S:x.” (x

= 1 or 0).

 A SMS with the text “O1:xxxxx.” or “O2:xxxxx.” (xxxxx = seconds) configures the switching

time of the relays. The STD35 saves these settings so that they are still available after the
supply voltage has been restored.

 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 “O1OFF.” permanently switches off relay 1. Relay 2
reacts accordingly to SMS messages with “O2ON.” and “O2OFF.”.

 The SMS “A1:xxx.” or “A2:xxx.” (x = seconds) sets the delay after which a reply SMS is sent

after an output has been activated. This can be helpful if you want to switch something on
or off and would like to measure the result of this output control with one of the inputs of
the STD35. Therefore the new status

after

the switching of the output is transmitted. If

parameter is set to “0” no message will be sent.

 With a SMS containing the text “I1:xxx.” or “I2:xxx.” (xxx = seconds) you can configure the

time the inputs have to be activated before the STD35 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 is deactivated for the configured Time. The
default value is x=0 which means that the STD35 will send an event alarm in case the input
has been activated longer than the configured time.

Please note that the brackets “<“ and “>“in the following commands are not part of the

commands but are included in order to increase the readability of the overview!

Four additional alarm numbers (mobile phones) can be defined using C2: - C5: commands.
These numbers are allowed to set relay 1 by a call and they are informed via SMS in case of
Start-up or events. These numbers are not allowed to send configuration SMS messages unless
they include the password in the SMS.

If an alarm number is given in international format, the number must start with ‘+’.

(e.g. [phone])

22

 With the “PN:<4digit password>.” command the password can be changed. The password

can include letters and figures but no special characters are allowed. All letters have to be
in capital. The standard password (factory setting) is the last 4 digits of the IMEI (see
chapter SMS Commands).

 The texts of the event or start-up SMS can be changed with the commands “E1:<text1>.”,

“E2:<text2>.”… and “PT:<startup text>.”. The message length must not exceed 64

characters. Do not use command syntax inside a message text. The ‘.’ is the
terminating character of the text. Each new text must be sent in a separate SMS.

 You can generate an extended clip list of 1000 clip numbers. The numbers stored in the clip

list are allowed to switch relay 1 with a phone call. Use “CL:” to generate the clip list and
add further phone numbers. With “CD:” you can delete a phone number from the list. Be

aware that you cannot read out the clip list (getting SMS messages) because it could by far
exceed the size limitation of SMS texts.

 With the command “TOx:<text>.” (x = 1 to 10, see command list above) an email address

for the particular events is configured. 5 email Adresses can be configured, divided by <;>.
The maximum length of the particular email addresses is 25 signs.

 With the command “SUBx:<text>.” (x=1 to 10, see command list above) the subject of the

particular emails is configured. The maximum number of sings for the subject is 128 signs.
The predefined text is: “STD35 Event x”.

 The content of the Email is configured with “BODY:<text>.”. The maximum length is 143

signs.

 The email sender address (of the STD35) is changed with “FROM:<text>.”. The maximum

length is 25 signs.

Please note that all commands listed in the section “Configuration SMS” require the 4-digit
keyword at the beginning.

The STD35 offers you the possibility to get messages via SMS and via e-mail.

8.1 Configuration of the E-Mail functionality

By default if the user has correctly configured the APN settings and the receiver email address
email functionality should work. This is because smtp settings are be default already
configured using the CEP email server.

If you need a full stop "." in a parameter as it is for example in an e-mail address, the
complete parameter has to be put into inverted commas (“...”) (e.g. "[e-mail]"), as
otherwise the "." would be seen as the end of the command.

GPRS settings

(to set up an internet connection)

Name of the APN (Access Point
Name)

APN:<text>.
User name for APN

APNUSR:<text>.

Password for APN

APNPWD:<text>.

 With the commands “APN:<text>.”, “APNUSR:<text>.” and “APNPWD:<text>.” you make

the basic settings to build up a GPRS (internet) connection. You need to get the necessary
data from your GSM network provider

9 Connecting the camera

The STD35 is offers the possibility to monitor an object or a room with the help of the CEP
camera optional accessory for the STD35

A picture can be sent as an attachment to the preconfigured e-mail address in the case of an
alarm. This allows you to take further action if necessary (e.g. call the police if you see a
burglar on the photo)

To be able to use this functionality you only have to connect the CEP camera to the camera
plug on the STD35 (see picture 1) and to activate the email-feature and the camera.

After the software of the STD35 has recognized the camera the pictures can be sent via e-mail
in the following ways:

 E-mail with JPEG attachment in alarm situation
 E-mail with JPEG attachment after incoming call
 E-mail with JPEG attachment after SMS request

In case the light intensity is not enough at the survey area the infrared light of the camera will
be activated automatically. Please note that due to the infrared light there will be a loss of
colours in the picture.

The CEP camera has an adjustable sun shade (metal plate over the camera). Please take into
consideration when adjusting the sun shade that the shadows are often changing during the
day.

TIP:

To make sure that all desired objects will be in the picture, that
the sun shade is in a good position and/or that the illumination
of the room will lead to satisfactory picture we recommend to

take “test pictures” after the installation. Only then you can rely

on the full functionality of the CEP camera.

10 Configuration Tool

Besides configuring the STD35 via SMS or using a configuration call it is possible to use the
CEP configuration tool to implement all setting. This tool allows the user to connect the device
to a standard PC via a special STDx accessory cable.

Once the cable is connected the STD35 can be monitored and completely configured using the
software provided. The configuration tool allows the user to configure devices without having
to manually construct SMS commands or send any SMS to the device.

You will get the further information via [e-mail].
