1.1 GSM-2 Overview

The GSM-2 modem is a GPRS modem with an integrated data logger and email program.

When connected to a external level sensor the GSM2 becomes a complete level modem logger.

The user doesn’t have to visit the measuring location anymore to receive the measured data.

This system eliminate the need of big installations like poles for solar panels and antenna, because it fits into standard

measuring-points with 2 inch tubes.

Just put the whole GSM-2 Unit into the measuring-point and covered it with the lock-unit.

A Battery supplies the low power consumption GSM-2 Unit and it will last for years.

The built-in barometric sensor enables the robust AA-Measurement and takes care of real-time barometric compensa-

tion.

A unique feature is that the data is exchanged by email. The KELLER Datamanager-2

software reads the emails or SMS and stores the data in an SQL database.

A measuring spot is recognized by the cell-phone number the data comes from.

The open-source character of the SQL database makes it possible to grab data from it by 3rd party-software so integra-

tion in existing data-acquisition systems is possible.

From the database all data from all modem loggers can be visualized and, exportable

(ASCII, WISKY, GWBASE etc) and filterable. Also reports can be made directly from the

database and even the location of the measurements can be displayed in Google Maps.

Other functionality offered by the GSM2 are alarming SMS / Email or GSM-2 configuration by Email.

1.2 GSM-2 features and advantages:

� GSM-Module and Datalogger in one device

� Easy installation (Just drop it in a standard measure-point)

� Small size (only 48mm in diameter)

� Low price

� Batterie powered / Low power consumtion (Battery last for years)

� Free software

� GSM Quad Band frequency module (cover the whole world)

� GPRS connection (low price connection to internet)

� Waterproof

� Smaller then 2 “ in diameter

� Built in Atmospheric pressuresensor (AA-Measurement)

� Remote configuration

� Interface for diagnostic

� Different interfaces for Sensors

� …….

2 General description / GSM-2 Communication

2.1 GSM DataManager

The GSM DataManager is a PC-Software to collect the transmitted measurements (from GSM-2 via Email or SMS) and

store it in a MySQL database.

The functionality of the GSM DataManager is described in the GSM DataManager Manual.

2.2 Data transfer

The data transfer takes place by e-mail or SMS.

The GSM-2 send the logged or measured data in a configurable interval.

A complete message is sent within 10 seconds.

Data transfer takes place into two directions. From and to (change configuration) GSM-2.

The Email box is used to store the data until the collecting program “GSM DataManager” or the GSM-2 has read it.

The GSM-2 can send Alarms or Measurements by SMS.

2.3 Configuration

First configuration is done on site at installation by a cable-connection from the PC to the GSM by the GSM-2 Setup

program.

The settings are stored in the GSM-2 and sent to the “GSM DataManager” by Email, where the new unit is registered

automatically.

Changes in GSM-2 configuration are made remotely in the “GSM DataManager” and transferred to the GSM-2 by

Email. The GSM-2 checks his Email-box in a configurable interval and if new configuration is available the configura-

tion is stored.


- 6 –

2.4 Measurement / Data logging

The GSM-2 measures in a configurable interval all sensors/channels and stores it in a EEPROM.

After a configurable amount of stored data, the data-transfer takes place.

Alarm functions are configurable and messages are sent immediately if alarm condition is true.

2.5 Power management

The unit is in a sleep mode only the real-time clock is active.

For measurement, the supply of the sensors are switched on for a short time (~5 seconds) and after the measurement is

done, the measurements are stored and the supply is switched off.

To send a message, the GSM-Module is powered on and within a few seconds, the messages are sent.

This is the most power consumption task. But due to the battery with high quality/capacity and low self discharge, the

battery will last for many years.

For Example, if you measure every minute and send data once per day, the battery last for >10 Years.

3 Minimum equipment for GSM-Data-Logging

To run a data-logging-system you need at least:

� GSM-2 Unit including Water-level-sensor

� SIM-card

� PC with GSM DataManager Software and MySQL database and internet connection

� One Email account (accessible from GSM-Network via SMTP/POP)

4.3 How to open and close the GSM-2 housing

Open To open the GSM-2 housing, just push from behind aginst the bottom of the housing/piston and the inside will shift out.

Close

To close the unit, push to the top of the housing/piston until it stops.

Be sure that that the piston is totally inserted.

Ensure that the holes on the top of the casing are completely visible. These are provided to allow water to drain off, so

that it does not collect inside the unit.

A bag containing silicate desiccant is used to protect the sensitive electronics from humidity. Push this bag together

with the GSM module into the sleeve.

The module can now be installed, together with the appropriate sensor, at the measuring point.

5. Connector for sensors

6. Silica gel bag

7. PG-Adaptor

4.5 Insert or release the SIM-card

As with a mobile phone, a SIM card is required to transfer data. We recommend the use of a prepaid card. In this way,

if the configuration is incorrect, only the amount of credit on the card can be used.

Before starting to use the SIM card, all SMS messages still on the card should be deleted (both sent and received SMS).

Ensure that there is always sufficient credit on your card. Your telephone provider will tell you about the various

possibilities for topping up credit.

Insert SIM card

Insert and pull out SIM card only if Battery is disconnected.

The SIM card is pushed as far as it will go into the slot.

See picture how the SIM card is orientated before inserting.

The card will lock when it is inserted it right.

In wrong orientation it will not fit in and will not lock.

Release SIM card

To release SIM card, slip lock of the SIM card holder to the left side.

4.6 Connect / exchange Battery

To power the unit, the black four-pole battery plug must be connected to the corresponding socket on the circuit board.

Ensure that the plug tab is pointing down (see picture).

After plugging in the battery plug push the battery into the battery holder.

4.7 Antenna connection

Stub antenna

Screw the stub antenna on the corresponing SMA plug locatet at the

top of the GSM-2. Make sure that is tight enough.

The antenna comes with a gasket in it.

If you use other antennas or connectors, make sure that is sealed.

Tab down

4.8 Adapter socket / level sensor connection

The plug to connect several sensors is located at the end of the GSM.

To connect a level sensor, the adaptor socket is required. Feed the sensor cable through the sleeve, and connect the

relevant cable ends to the corresponding terminal strip.

The adaptor sleeve has to be tightened very well with an open-ended spanner, because the whole weight of the level

sensor has to be carried by this adaptor sleeve.

There are two rubber seal with different diameter for different cable diameters.

If a level sensor with a reference tube is used, the tube should be connected inside to the barometric pressure tube by a

T – peace which leads to the outside of the GSM-2 housing and guarantees pressure equalisation.

Make sure that the GSM-2 housing is still sealed.

A bag containing silicate desiccant is used to protect the sensitive electronics from humidity. Put this bag in the GSM-2

housing like you can see it in the picture.

The circlip is mounted at the inside of the adapter socket, preventing loosen the thread.

5 Lock-Unit

The lock-unit for GSM-2 with antenna cover fits to standard size 2 inch measure points.

It is a assesoiries.

The GSM-2 fits in the lock unit and the antenna is covered by the upper peace.

6 Battery lifetime

The displayed value in GSM-Setup and DataManager is the battery capacity calculated in the GSM-2 as a percentage

of remaining capacity.

If the value is below 30%, it is recommended to change the battery. Once the battery has been changed, the value is

again shown as 99%. However, this is also the case each time power is restored after a disconnection. For this reason,

the battery should be disconnected only for replacement.

To ensure reliability, the battery should be replaced every five years.

The calculated values in the table below shows how long the battery can last at different conditions.

This should give you a idea how to configure the GSM-2 and how long the battery can last.

The calculation is based on following conditions:

Temperature profile : Switzerland with peak temperature –20°C / 40°C

GSM connection : good signal quality / GPRS connection

Case Measurement interval E-Mail-Datatransfer interval Calculated lifetime

A --- 24h > 5 years (49 years)

B 1h 24h > 5 years (27 Years)

C --- 1 h 3 Years

D 1 min 1 h 1.6 Years

! The value in the table is just a calculation, outside conditions (like temperature and storage time) have influence on

battery capacity and life time.

Battery has self discharge and we recommend to replace the battery every 5 years.

Calculated lifetime greater 5 years is just to give a idea about consumption.

# # Sign is used as main command separator

/ / Sign is used as command separator

11 Data connection

This function was used in the GSM-1. For compatibility reason it is also supplied in the GSM-2. We do not

recommend to use that function in new projects, use the E-Mail function.

When a data connection is established, the data from the Data collector DCX connected to the GSM can be accessed

world-wide via modem. If a data logger is connected, the entire memory content can be read out. It is also possible to

reconfigure the logger.

A data connection can be made only from the module to the PC. The user is always called from the GSM module. The

call time can be specified in the configuration. An additional, more flexible possibility is to send an SMS to the module,

which requests a data connection (with the instruction “<”). The next time the module checks incoming SMS messages,

it recognises that a data connection has been requested. It immediately dials the relevant number and establishes the

data connection with the user’s modem.

Preparation for connecting the call

The call can be made either with an analogue or a digital (ISDN) modem. The use of an external modem is recom-

mended.

11.1 Using “Modem Reader” for automatic read-out

The “Modem Reader” software allows calls to be automatically received from the GSM, and the current record read

from the DCX and saved. This all runs in the background.

Once the program has been started, it waits until a call is made to

the modem, and starts to read the data. Once the record has been

read and saved, the line between the GSM and the modem is

disconnected and the program waits for the next call.

12 E-Mail configuration

We recommend to use (at least) 2 E-Mail accounts in conjunction with the GSM DataManager.

1 E-Mail Box where the GSM-2 Modules send the measurement and the configuration and 1 E-Mail Box for configura-

tions sent from GSM DataManager to the GSM-2 Modules.

This helps to save battery and money, because the modules download only Mails from the E-Mail Box with configura-

tion (if new configuration sent from the GSM DataManager) and not also messages with measurement content from all

the modules communicating to this Mail address.

12.1 1 E-Mail account for outgoing and incoming messages

Advantage: only 1 e-mail box for incoming and outgoing messages

Disadvantage: all messages(configuration and measurements) are downloaded to each used GSM-2 module that

produces much traffic, cost and limits battery life.

12.2 2 E-mail accounts one for outgoing and one for incoming messages

Advantage: separate e-mail box for incoming and outgoing messages.

All Measurements are sent to same E-Mail-Box.

All configuration-mails are downloaded to GSM-Module.

Disadvantage: all configuration-messages are downloaded to each used GSM-2 module,

more traffic, cost and battery life.

12.3 many E-mail accounts one for outgoing and one for each GSM-2 for incoming messages

Advantage: separate e-mail box for incoming and outgoing messages.

All Measurements are sent to same E-Mail-Box.

Only configuration-mails for the corresponding GSM-2 are downloaded to GSM-Module.

Disadvantage: you need many e-mail accounts

Hint: You can build Groups (Measure-networks), which use the same In-Box.

14 First installation step by step

The configuration below shows how a installation and configuration can take place. It is a standard configuration

suitable for most applications.

Sample shows following configuration:

� GSM-2 with level senor (Series 36 XW) connected. Connection RS485 and 12 Volt supply.

� 2 E-Mail accounts. [email protected] to send Messages with measurements to DataManager,

[email protected] to send new configuration from DataManager to GSM-2.

� Measure interval is 1 hour, sending E-Mail with 24 measure values every day (24 hour)

� check interval for incoming E-Mail (configuration from DataManager to GSM-2) every day (24 hour), same

time like sending measurements to DataManager.

14.1 connect level sensor

Feed the sensor cable through the sleeve, and connect the

cable ends to the terminal strip.

Connect the Series 36 XW level sensor like .

Blue : RS485A

Yellow : RS485B
