Safety Instructions

 All wiring work has to be done in a voltage free state only.
 All cables and wires which are energized and connected to the device, the module, or components

have to be checked regularly for any damage to the isolation shielding or fractures in the cables. If
the supply cables are visibly damaged the device has to be taken out of operation immediately until
the faulty cable has been exchanged.

 Before putting a device into operation, it has to be clarified, whether this device or module is

appropriate for the field of application. In case of doubt ask a specialists or the manufacturer of the
device.

 Please note that we are not responsible for any errors in usage or connection. Therefore we cannot

accept any responsibility for consequential loss.

 Before opening the device always disconnect the mains adapter or make sure that the device is

disconnected from the power supply.

 Components, modules or devices have to be built into a housing before they are put into operation.

During installation they should not be connected to any power supply.

 You should only use tools on components, modules, or devices if they are disconnected from the

power supply, and residual electric charge (which may still be stored in some components inside the
device) has been discharged.

 When using components or modules it is necessary to strictly observe the specification given in the

corresponding description of these components.

 If a description for a private end-customer does not clearly state which electric data is valid for a

component or a module, how to wire the device, which external components, or additional devices

requirements for safety!

2 Operating Conditions

Operate the STD35 only with a supply voltage between 7-32V DC and have in mind the polarity! (see
Figure 1) 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 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 (board) 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.

3 Application Areas

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.

4 STD35 Product Overview

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).

Please note: Only use standard [1.8V / 3V] SIM Cards!

Table 1: Available Connectors

Please note the following instructions:

 Screw terminal “Outputs”: Here, electrical loads are connected to the respective relay. By activating

an output, the respective rekay RLY 1 or RLY 2 establishes an electrical connection between contact
1 and 2. Please consider the limit values for all RLY’s (see article 10 Technical data)

 Screw terminal “Inputs”: The inputs are activated as soon as a voltage is applied within the

specified range between the terminals (e.g. DIN1 and GND refer to Section 10, “Technical data”).
The analog inputs (terminals F & G) use the ground potential of the power supply (ie, terminal E).

 Screw terminal “Power Supply”: Power supply is applied on screw D (VIN ) and screw E (GND).
 The used terminal blocks are designed for cables with a cross-section of 0.08mm² to 1,3mm² (both

single core and multistring).

 The (FME-Female) connector “Antenna” is used to connect the GSM antenna.

8

Please observe the maximum output voltage of the relays and the maximum input
voltage of the inputs! (Refer to Section 2 Operating Conditions).

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.

Status LEDs:

The STD35 has several LEDs that indicate the operating status:

 L1 (Green): status of the power supply. It flashes in green when the external power is applied to the

device.

 L2 (Yellow): GSM status. This LED flashes once every 2 seconds for a short moment when the device

is logged into the GSM network.

 L3 (Yellow): GSM status: The LED flashes faster during a DOTA Update.
 L3 (Red): General Status LED. Cyclic flashing 1x every 2 seconds: the device is ready for use.L4

(Green): General Status LED This indicates whether an administrative telephone number is
configured or not (see section 5.1 General preparations.

An alternate flashing of the LEDs L3 and L4 indicates that the device has not yet been configured.

Button:

A hardware reset of the device is performed if the switch is pressed for more than 7 seconds.

5 Quick Start Up

The following section provides step by step instructions to get the STD35 up-and-running without
extensive setup.

5.1 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.

You can also 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.

5.2 Preparing the Device

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.

When delivered, the internal battery is not connected to the board (see Figure 1). Please connect it to
the board with the battery connection cable to the appropriate connector.

After this step, connect the external power supply using the appropriate screw terminal.

Please always observe the proper polarity of the power supply (see Figure 1).

5.3 Call-based Configuration

After having connected the power supply and turned on the device for the first time, the General Status
LEDs (L3 & L4, see Figure 1) will start blinking alternately. This indicates that the device is in its original
factory settings. 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.

The STD35 is now ready and can be configured.

In the next step, 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.

5.4 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”

6 SMS Commands

There is a wide range of special commands which can be used to configure the device, request
information or to 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. The format of the SMS commands is explained in Section Fehler! Verweisquelle konnte

6.2 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 E-Mail.

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

Example:

The command

E1: Supply = $ VMAINS $ V.

Table 8: Variable substitution

In the default factory settings, this password consists of the last 4 digits of your
device’s IMEI. This IMEI (International Mobile Equipment Identity) number can
be found on the back of the unit.

If you change this password, 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 USB interface.

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)

configures the device so that with active input 1 it sends a message in which the current supply voltage
is specified. This message could then look like this (example value):

"Supply = 11,712V".

6.3 Format of SMS Commands

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

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
(see examples in Table 9).

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. "[e-mail]"),
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.

6.4 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).

16

 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.

[phone])

 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 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

7 E-Mail functionality via GPRS

Figure 2: E-Mail functionality via GPRS

The STD35 enables you to get messages not only via SMS but also via E-Mail. You need to have an active
E-mail account with an SMTP E-Mail provider in order to use this feature, and the following settings
have to be made for the E-Mail service:

 name of the SMTP server (eg smtp.mailprovider.com or 192.168.234.12)
 username to log on to the SMTP server
 password for logging on to the SMTP server

The device is configured by default to use the CEP E-mail server. If you wish to use your own E-Mail
service, please ensure that it supports plain text authentication. Please also note the information in the
next section.

7.1 Configuration of the E-Mail functionality

E-Mail functionality should work by default if the user has correctly configured the APN settings and the
receiver E-Mail address. SMTP settings are by default already configured using the CEP E-Mail 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.

Name of the APN (Access Point Name)

APN:<text>.

User name for APN

APNUSR:<text>.

Password for APN

APNPWD:<text>.

In most cases it is not necessary to configure any of the SMTP settings as the device
come preconfigured for the e-mail server subscribed by CEP, which is a free service for

STD35 users.
