3 Security tips

Modems from the series VARIOMOD are electronic appliances and may not be used for any other purposes. Mounting

may only be carried out by electronic specialists according to the generally recognised codes of practice and according

to the standard requirements for the installation of telecommunication systems and devices.

Before assembly, please examine the appliance for any exterior, obvious transport damages and on location check the

electrical operating conditions. Please pay special attention to the voltage ratios for the modem connection. Connection

may only be carried out using suitable tools and when the appliance is switched off.

Attention!

The device should only be operated when the cover is closed because power is applied to some components.

Disconnection of the modem from the electrical circuit

In the electrical circuit of the modem an easily accessible, all-pole disconnector or a one-pole disconnector has to be

provided for the outer conductor (if there is an unmistakable neutral conductor in the power cable).

Disconnection of the modem from the control circuits with power

Due to the fact that applying power to the alarm input (terminal 1 and terminal 2) is permitted, it must be ensured that

this electric circuit can be disabled by an easily accessible all-pole disconnector.

Assembly of the external aerial

When assembling the exterior aerial which is available as an optional accessory, the assembly fixing bracket must be

earthed against lightning by a specialist.

Inserting the SIM card in the GSM/GPRS device

Only insert the SIM card when the appliance is switched off!

5.2.1 Connection and selection of the meter interface

5.2.1.1 General

A CL-, RS232- or RS485 interface are available as an interface to the meter. As an option the modem can be equipped

with a CL interface and two RS485 interfaces.

Since the meter interface can be temporarily switched during operation a configuration record (baud rate, data format,

Mode C/E support) is saved for each interface. A description of how to change the interface can be found in chapter „9

Temporary switching of the interfaces“.

5.2.1.2 Standard interface selection via configuration

The standard interface is selected with the configuration software VARIOMOD Manager.

5.3 Power supply

Power (100 V AC...240 V AC or 135 V DC...240 V DC) is supplied via the following terminals:

Terminal 8 - Phase (L) or positive pole

Terminal 9 - Neutral conductor (N) or negative pole

Security tip:

Disconnection of the modem from the electric circuit

In the electrical circuit of the modem an easily accessible, all-pole disconnector or a

one-pole disconnector for the outer conductor (if there is an unmistakable neutral

conductor in the power cable) has to be provided.

5.4 Alarm input

Control of the alarm input with 100 V AC...240 V AC or 135 V DC...240 V DC takes place via the following terminals:

Terminal 1 - Phase (L) or positive pole

Terminal 2 - Neutral conductor (N) or negative pole

Security tip:

Disconnection of the modem from the power electric circuit

Due to the fact that it is permissible to apply voltage at the alarm input (terminal 1 and

terminal 2) it must be assured that this electric circuit can be disconnected by means of

an easily accessible all-pole disconnector.

6.2.2 Assembly of the aerial

The magnetic fixing aerial (provided) is screwed to the FME-sleeve of the VARIOMOD. In order to guarantee an

optimal reception the aerial should be mounted outside the (meter) cabinet, upright on a magnetic surface.

With the assembly of an external aerial (available as an optional accessory), the assembly

fixing bracket must be earthed against overvoltage by lightning by a specialist.

Figure 9: Assembly of the aerial

6.3 Ethernet-Modem

To connect the module to a network, plug the network cable into the left socket [1]. The plug must snap in. The other side

of the network cable is plugged into a network socket [2], into a switch [3] or into a network socket of a computer.

6.4 Switching on the device

After applying power (power-LED lights up / flashes) or after a reboot (reset) the VARIOMOD performs an initialisation.

As a rule, this procedure takes approximately 20 to 30 seconds.

During the initialisation phase the power-LED flashes. If the Error-LED flashes or lights up this means there is

interference. In this case please contact your supplier.

6.5 Local configuration

The modem can be locally configured via the preconfigured meter interface or via the interface selected by means of the

service button.

If the preconfigured meter interface is used, the parameters used with the connection setting in Variomod Manager are to

be used.

Typical paramaters for the preconfigured meter interface of the VARIOMOD are 4800 baud and the data format 7E1 (7

data bits, even parity and 1 stopbit).

When selecting the interface via the service button, 9600 baud and the data format 8N1 are to be used.

Some settings are only taken over after a reboot. After exiting the configuration mode, the device is automatically

restarted.

The device is configured with the program VARIOMOD Manager.

6.6 Remote configuration

An already installed VARIOMOD can also be configured remotely. For this it is necessary to establish a data link to the

VARIOMOD. After establishing a data link the configuration takes place as with the local configuration.

Please note that some of the settings are only adopted after rebooting the device, resp. after ending the data connection.

The device is configured with the program VARIOMOD Manager.

6.8 Necessary settings

Depending on the device it is necessary to make some settings. A detailed description of the commands can be found in

a separate document.

6.8.1 General settings

It may be necessary to adjust the VARIOMOD baud rate and the data format to match the respective meter interface of

the connected end device.

If a connected meter operates in accordance with IEC 62056-21, protocol mode C/E, this mode is also to be activated for

the meter interface (default) and it’s to set the starting baud rate from the meter as interface rate.

If the VARIOMOD should only accept calls at certain times, a call acceptance slot needs to be defined (see chapter 10

Call acceptance slot).

For all settings which have time dependent functions (e.g. call acceptance slot etc.) it is necessary to set the device clock

(see chapter 13).

6.8.2 VARIOMODgsm/gprs

settings

As a standard the VARIOMODgsm/gprs

is configured for operation with SIM cards (PIN „0000“). If a SIM card with a

different pin should be inserted the VARIOMODgsm/gprs

is to be reconfigured with the VARIOMOD Manager. Operation

with SIM cards with a deactivated pin inquiry is also possible. Any PIN number can then be configuring.

6.9 Configuration

Configuration of the VARIOMOD can be done locally or remotely with Windows software VARIOMOD Manager.

7 Data transfer

The VARIOMOD modem allows a transparent data transfer which means that the modem does not evaluate or influence

the data transferred in any way. The data transfer is supported in accordance with IEC 62056-21 and DLMS.

As a starting baud rate the configured baud rate of the meter interface is used.

Once the interface has received the confirmation string from the control centre the baud rate is converted and the meter

can send its data to the control centre.

A repeated read out of different meters with a data bus is possible in the following way: With recognition of the request

string, the VARIOMOD switches the interface back to the starting baud rate before passing the request string to the

meter.

After ending a data link the VARIOMOD sends out a static break signal (according to VDEW-specifications) to the meter

interface lasting 1000 ms to stop a read out process which may have been interrupted by the control centre also at the

meter. Furthermore the VARIOMOD’s meter interface is set back to the starting baud rate.

Note:

If the VARIOMOD should be used for data transfer of further protocols, e.g. DLMS or gas resp. water meters which

are not operated in the protocol modes C or E, it is recommended to deactivate the support from protocol mode C/E

according to IEC 62056-21 because every character string with „/?...“ is temporarily stored in the VARIOMOD’s buffer

in this mode. This leads to gaps / interruptions in the data stream. For electricity meters this is irrelevant because

these characters do not appear again in the data stream.

To protect the VARIOMOD modem from unauthorised access the configuration mode and incoming data links can be

protected with a password both locally and remotely.

Connection establishment procedure:

As a separator the VARIOMOD recognises the symbols „#“ or <CR>.

To simplify the usage within readout systems whose control centre software does not support the password inquiry the

password including the separator can be placed in front of the actual request string.

Example:

Password: 123245678#/?! (123245678 = Password, # = Separator, /?! = Prompt sequence)

With a correct password, the transfer takes place immediately after the check.

9 Temporary switching of the interfaces

9.1 Switching via a password

Switching to another interface takes place during the connection process via a data password. The remote read out head

office must however support the transfer of a modem data password. A switch is only possible once per data connection.

Function:

In order to change the interface, the separator „-“ and the channel number are inserted between the password and the

password separator (# resp. <CR>).

Examples:

12345678<CR> no switch of the current interface

12345678# no switch of the current interface

12345678-0# switch to the standard interface

12345678-1# switch to the CL1 interface

12345678-2# switch to the RS232 interface

12345678-3# switch to the RS485 interface

12345678-3<CR> switch to the RS485 interface

After ending a data link you return to the standard interface.

9.2 Switching via a device address

With an active mode C/E support the interface can be switched during an existing connection via the meter address

(acc. to IEC 62056-21).

Function:

To change the interface, the separator „-“ and the channel number are inserted between the meter address and the

character.

Examples:

/?0815673!<CR><LF> no switch of the current interface

/?0815673-0!<CR><LF> switch to the standard meter interface

/?0815673-1!<CR><LF> switch to the CL1 interface

/?0815673-2!<CR><LF> switch to the RS485 interface

/?0815673-3!<CR><LF> switch to the RS485 interface

After ending a data link you return to the standard interface.

With every change of the interface the stored configuration record (baud rate, data format, mode C/E support) for the

respective interface is set.

10 Call acceptance slot

The function of the call acceptance slot is used primarily with analog VARIOMOD with telephone sets switched in series.

The call acceptance slot is a period of time in which the VARIOMOD accepts telephone calls. It is also possible to set the

number of ring tones after which the VARIOMOD accepts a call.

Examples of using the call acceptance slots:

Figure 12: Call acceptance slots

The VARIOMOD takes calls at the following times:

Monday from 0:00 to 2:00 o’clock

Monday to Tuesday from 22:00 o’clock to 02:00 o’clock

Tuesday to Wednesday from 22:00 o’clock to 02:00 o’clock

Wednesday to Thursday from 22:00 to 02:00 o’clock

Friday from 2:00 o’clock to 22:00 o’clock

Saturday from 22:00 o’clock to 0:00 o’clock

On Sundays no calls are taken.

Figure 13: Settings of the call acceptance in the VARIOMOD Manager

Note:

The call acceptance slots are configured with the program VARIOMOD Manager. With deactivation of the call

acceptance function the VARIOMOD takes all incoming calls (default). With an active call acceptance function, calls

are taken after 15 ring tones outside the time slot for service purposes.

13 Device clock

The VARIOMOD can be equipped with a crystal controlled real time clock (RTC) with a running reserve of at least 5

days.

With an active mode C/E the VARIOMOD takes over the time set command from the meter for synchronisation of the

clock.

The following time formats are supported:

W2 C003 [YYMMDDhhmmsswwny]

W5 0.9.1 Z6 [hhmmss]

W5 0.9.1 Z8 [hh-mm-ss]

W5 0.9.1 Zs7 (seasonal) [yhhmmss]

W5 0.9.2 D6 [YYMMDD]

W5 0.9.2 Ds7 (seasonal) [YYMMDD]

W5 0.9.2 D8 [YY-MM-DD]

With season time stamp formats „y“ has the following meaning:

y = 0: Normal time

y = 1: Summer time

14 Automatic sending of an SMS

With activation of the alarm input a predefined SMS can be sent to the headquarters or to a mobile phone or to a SMS-

capable landline.

14.1 Settings

Telephone number of an ETSi conform service centre (e.g. 0193010 German Telecom)1

Destination number (ITD)

SMS-Text (ITN), length up to 160 characters

14.2. Functions

Automatic sending of an SMS starts when voltage is applied to the terminal „alarm input“ for at least 300 ms. The modem

can be configured in a way that a transmission takes place with a switch from on to off (1→ 0) or from off to on (0→ 1) or

with both.

A renewed sending of an SMS is only possible again when the alarm input is switched off. By means of this, with a

continual activation of the alarm input a permanent sending of an SMS is prevented.

If the SMS cannot be sent due to an occupied gateway or an unavailable telephone network1, the sending is repeated up

to 3 times at intervals of 20 seconds.

15 Automatic sending of E-mails

By activating the alarm input a predefined E-mail can be sent.

15.2 Functionality

The automatic sending of an E-mail starts when the state at the terminal „Alarm input“ changes for at least 300 ms. The

modem can be configured in a way that a transmission takes place with a switch from on to off (1→ 0) or from off to on

(0→ 1) or with both.

16 GPRS

For use of the GPRS functions, the VARIOMODgprs

is addressed via its IP-address.

You are informed of the GPRS-APN (Access Point Name), the user password and the password by the mobile telephone

system provider.

The modem can be operated in three different GPRS modes: as a TCP/IP server, as a FTP-client and as a IP-telemetry

client. If no mode is selected, the modem operates as a transparent GSM Modem.

16.1 TCP/IP-Server

16.1.1 Functionality

By means of the IP address of the SIM card a TCP connection with the modem is established via the GSM mobile phone

network. By means of this, the connected meters (e.g. up to 31 meters via a RS485) can be read out transparently. The

TCP-Port which is used is set to 8000 (fixed).

16.2 FTP-Client


The modem reads out the meters at configured times and saves the read out meter data as a file(s) on a FTP server.

Table 1 (billing relevant data) and/or table 4 (service data) and/or a load profile can be read out.

The following read out intervals are possible:

16.3 IP-Telemetry Client


The modem establishes a connection to the IP telemetry server via the GPRS mobile phone network.

By means of this, the connected meters (e.g. up to 31 meters via a RS485) can be read out transparently.

After GPRS-registration with the mobile phone network provider the dial-up connection of the TCP/IP connection to the

IP-telemetry server takes place according to the following procedure:

16.3.1.1 Dial-up connection to the IP-telemetry server

Connection takes place via a connection attempt to the primary IP address of the IP-telemetry server.

If no connection takes place, the attempt is repeated two times after a one minute interval each time. If the connection

fails again, registration to the secondary server is attempted. If this is also unsuccessful (3 attempts) the registration

process is repeated again after 30 minutes. If this also fails, registration is repeated after one hour. If again no

registration takes place, the registration attempt starts again after 24 hours.

16.3.1.2 Registration on the IP-Telemetry server

After successful registration on the TCP/IP-level, registration (login) on the server takes place. Here 3 attempts are also

allowed. If these attempts fail, the process is repeated after 30 minutes. If dial-up connection fails again, another attempt

is tried after 60 minutes. If login is still not successful the connection to the IP-telemetry server is disconnected.

Registration (login) now takes place on the secondary IP-telemetry server. If registration was not successful or if only a

IP-telemetry server exists, the next attempt takes place 24 hours later.

Figure 17: Login to the IP-Telemetry server

16.3.2 Settings

Following parameters can be configured with the Variomod-Manager:

Primary IPT-Server and IPT-Port: IP-Address or host name as well as the port of the IPT-Server. As a default

the port is 26862.
