This is an example of text for the main body. Style name: Text – Standard
2.1 GSM-Network in general
The GSM Network (Global System for Mobile Communications) is a standard for all-digital mobile phone networks.
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 InternetInternet, the GSM network was expanded to offer packet oriented data transmission (e.g. via GPRS) while keeping all other features and being fully backwards compatible.
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).
If the device is booked into the GPRS network 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. Please clarify, if necessary, with your mobile network provider the availability of this functionality.
2.3 Quadband Frequencies
A “quad band” device can use four different frequencies which have been assigned to the GSM standard, and therefore can be used with any GSM network in the world.
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, including Europe and Asia.
2.4 E-Mail via SMTP
SMTP (Simple Mail Transfer Protocol) is a method used to send E-Mails over the Internet. The STD35 establishes a connection to an SMTP server which will send the E-Mail to the given E-Mail address. The
STD35 comes preconfigured with an E-Mail service subscribed by CEP. Please note, however, that CEP does not maintain own infrastructure for the E-Mail service. Changes in external services may take place at any time and are beyond our control. For more information see chapter 8.
To be able to use this service you must have an E-Mail account with an E-Mail provider (e.g. AOL or
Yahoo) and the following settings have to be made which are different for every E-Mail provider.Name of the SMTP Server (e.g. smtp, mailprovider.com or 192.168.234.12)
User name to login to the SMTP Server
Password to login to the SMTP Server
The device comes pre-configured for use with the free CEP E-Mail server. If the user wishes to use thir own E-Mail service it is important to note it must support plain text authentication and E-Mails with no
in order to take advantage of this service.
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
Loads connected to the device are not allowed to exceed 30 W per relay.
The maximum output voltage is 250 V AC for output 1 and 2 and 30V DC for outputs 3-5
The maximum switching current for output 1 and 2 is 5A and for outputs 3-5 it is 1A
When installing the device make sure that the supply cable has a sufficient diameter
During operation the temperature must be in the range -30° to +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 positioning is required to operate the device.
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 E-Mails after status has changed at the inputs. A different utilization of the device other than the ones described here is not allowed.
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 standard mobile phones.
Apart from the STD35 you only need a valid SIM Card from any network provider (GSM850 / 900 / 1800 or 1900 MHz)
While using prepaid SIM-cards, always keep aware of the amount of remaining budget left on the card, so that in case of alarms a message still can be transmitted.
Typical fields of application are:
Opening (garage) doors
Switching on and off light and alarm devices as well as generating alarm messages (SMS or E-Mail)
Retrieval of information from door sensors, movement sensors or level sensors
You can for example open your garage door with a call or get a message (vian SMS or E-Mail) in case your house alarm system gets triggered. E-Mail

Table 1: Available Connectors
The first two terminal blocks (highlighted in blue) are the output terminals. Here, electrical loads are connected to the respective relay.
The third and fifth row of screw terminals (marked in purple) correspond to the Inputs. The inputs are activated as soon as a voltage is applied within the specified range between the terminals of the optocoupler.
Pins 5 and 6 of the fifth row of terminals correspond to the the analogue inputs AIN 1 (Input 4) and
AIN2 (Input 5). They share a common ground with the Inputs 1-3 (Pin 4 terminal row three)
The voltage supply is applied on pin 1 (VIN +) and pin 2 (GND) of the fourth row of terminals
(marked in red).
The maximum cross-section of the cables to be screwed into the screw terminals is 0,08 mm² - 1.3 mm² (both single core and multistring).
The (FME-Female) connector ANT is used to connect the GSM antenna.
Please observe the maximum output voltage of the relays and the maximum input voltage of the
The STD35 has several LEDs that indicate the current operating status.
If the module is logged into the GSM network, the yellow GSM LED will flash briefly about once every 2 seconds .
The green power LED lights up when the external power supply is applied to the device.
The button on the board is used for development purposes and can be ignored.
Please observe the maximum output current of the relays and the maximum input voltage of the inputs! Please refer to chapter 8 operating conditions for more information!
Quick start up
The following section provides step by step instructions to get the STD35 up-and-running 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). As an alternative, you could use the PIN “2468”. To change the PIN you can use a regular mobile phone. Please refer to your mobile phone manufacturer’s user manual for instructions on how to change the PIN.
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.
It is also possible to use a SIM card without a configured PIN
In the following we 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.
The “incognito” or “private call” function of the mobile must be deactivated in order to be able to administer the STD35. In other words, the Master Mobile has to transmit the mobile phone number with every call. Please refer to the user guide of your mobile telephone to change this setting.
To test the setting you can call a different mobile phone; there your phone number or name should be displayed.
6.2 Hardware preparations
Please insert the SIM card into the SIM card holder on the PCB prior to connecting the supply voltage and switching on 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. Move the top sideways in the opposite direction to lock the SIM card in place.
Now please connect the GSM antenna which is part of the delivery to the proper antenna connector on the STD35 board.
6.3 Call-based Configuration
After having connected the power supply and turning on the device, the green and red power LEDs will blink alternately (system start). Shortly after that the GSM LED will be activated. Now the STD35 will automatically attempt to connect to the GSM network. As soon as this is completed, the GSM LED will flash once every 2 seconds.
As soon as the red and green system LEDs are toggling the STD35 is ready and waiting for configuration.
Now call with the 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.
After a successful configuration it will automatically send an SMS 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”
Special commands are used in order to configure the device, request information from it or trigger certain actions. All the commands are designed to be easy to enter even when using a standard phone.
This chapter describes all the commands the device will understand and how to use them.

7.2 Using Variables
You can use text strings “variables” in order to display more information in event texts. 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 vian SMS or email.
The following table describes the available variables and the data they represent
$IN1$, $IN2$, $IN3$, $IN4$, $IN5$
$OUT1$, $OUT2$, $OUT3$, $OUT4$,
$IN1T$, $IN2T$, $IN3T$, $IN4T$,
$OUT1T$, $OUT2T$, $OUT3T$,
$VIN5$ last incoming CLIP number

EMAIL counter) current input value as a string (LOW or HIGH) current relay value as a string (ON or OFF) current input value as a integer (0 or 1) current relay value as a integer (0 or 1) battery voltage in milivolts (integer) battery voltage in volts (float) mains voltage in milivolts (integer) mains voltage in volts (float) input 4 voltage in milivolts (integer) input 4 voltage in volts (float) input 5 voltage in milivolts (integer) input 5 voltage in volts (float)
Table 8: Variable substitution
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 an SMS to the STD35 you can switch the outputs or perform individual configurations.
Those SMS have the format which is described below:
In order to avoid unauthorized usage, every configuration command to the STD35 must start with a 4digit password.
The (standard) password for all devices is 9851.
If you change this, you must note that all commands – also reverting to factory settings – presuppose knowledge of this password. If this is not known, resetting the password is only possible by using the
All commands (except R: and ST?) must end with a full stop “.”!
All commands can be sent in one SMS; each command has to be separated from the next by 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 APNsettings, the complete parameter has to be put into inverted commas (“...”) (e.g. "[email protected]"), as otherwise the "." would be seen as the end of the command.
Parameters for representing 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 an 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 an SMS with “ST?”
Configuration-SMS (Attention: 4-digit keyword is required!)
The SMS “R:” 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).
AN 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 an SMS with the text “O1ON.” from the configured mobile phone switches the relay 1 permanently on. AN 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 an 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
AN 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 vian 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.
With the command “PN:<4digit password>.” the password can be changed. The password can include letters and figures but special characters are not allowed. All letters have to be in capital.
The standard password (factory setting) is 9851.
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
Please note that all commands listed in the section “Configuration SMS” require the 4-digit keyword at the beginning.
