1. Description of working of the modem
The modem is intended for remote communication with data loggers ATV, ATX, ATP via cellular
network (GSM). In light of a customer, this way of communication offers the same functions like a
direct connection between the data logger and the computer (for example by using COM/USB
adapter).
The modem can be set and controlled with a program for data loggers and also with SMS messages
(but with restrictions). It is possible to select phone numbers, from which SMS messages are
accepted by the modem.
These are possibilities of usage the program for data loggers:
downloading data from the connected data logger
reading of current values from the connected data logger
setting up the modem locally via RS232 link
setting up the modem remotely via GPRS networking
setting up the connected data logger remotely
These are possibilities of usage the SMS messages:
sending of alarm SMS messages to preconfigured phone numbers (in case of beyond
the set alarm limits for measured values and binary inputs or in case of error
conditions)
getting of current values from the connected data logger
setting up the modem remotely (with restrictions)

2. General safety rules
The following summary describes a basic safety features related to device installation and
operation. Please read it properly before device installation. The following safety precautions must
be observed during all phases of the operation, usage, installation or repair of the device. Operate
the instrument in accordance with this manual to prevent damage of this device, damage of three-
side devices or electric trauma.
Risk of electric shock
Do not use the instrument without the cover. Use only a safety adapter with
the power voltage recommended by device manufacturer. Before connecting,
check that the adapter has undamaged cables and cover. Do not use the
instrument, if it does not work correctly. If the instrument seems not to work
correctly, have it checked by a qualified service person.
Qualified service and installation
Service should be performed by a qualified person only. We recommend you
use only original accessories to avoid possible damage. When connecting to any
other device, read its user guide for detailed safety instructions. Do not connect
incompatible products. It is forbidden to connect other devices, while the
device is under electric voltage. If a damage of the device occurs due to gross
violation of these rules, a free guarantee repair will not have to be executed.
Usage in hospitals
When in a hospital or other health care facility, observe the restrictions on
the use of mobiles. Respect the directions and switch the cellular device off on
places, where using mobile phones is forbidden. Medical equipment may be
sensitive to RF energy.
Switch off in aircraft
Switch off the cellular device before boarding an aircraft. Make sure it cannot
be switched on inadvertently. The operation of wireless appliances in an aircraft is
forbidden to prevent interference with communications systems.

6
Avoid fire and explosion
Do not use the instrument in an explosive environment. Do not operate
the cellular device in the presence of flammable gases or fumes. Switch off
the cellular device when you are near petrol stations, fuel depots, chemical
plants or where blasting operations are in progress. Operation of any
electrical equipment in potentially explosive atmospheres can constitute a
safety hazard.
Interference
Your cellular device receives and transmits radio frequency energy
while switched on. Remember that interference can occur if it is used close
to TV sets, radios, computers or inadequately shielded equipment. Always
switch off the cellular device wherever forbidden, or when you suspect that it
may cause interference or danger.
Service availability
Devices operate using radio signals and cellular networks. Because of
this, connection (SMS, GPRS, etc.) cannot be guaranteed at all times
under all conditions. Therefore, you should never rely solely upon any
wireless device for essential communications (emergency systems, safety-
related systems). Remember, for hi-reliability systems is redundancy
necessary. For more information please see IEC 61508.

3. The modem and its accessories
To use the entire facility, not only the modem, but proper accessories are also required.
3.1. Accessories needed to operation
The SIM card
The SIM card is necessary for correct modem operation. It makes possible to send SMS
messages and to communicate with the data logger remotely via GPRS. In addition,
GPRS data services must be activated for data transferring via GPRS. If the running
modem is used among areas with different mobile operators, GSM and GPRS roaming
(data roaming) must be also activated. Method and amount of payment for these
services are determined by your mobile operator.
A PIN code entering must be deactivated on the SIM card. For more details see the
chapter The SIM card on page 10.
The GSM antenna
The GSM antenna is also necessary for correct modem operation, the facility doesn’t
work without it. It must be mounted into antenna SMA connector. It is possible to use
the compact GSM antenna GSM-ANT which is offered by the manufacturer. In case of
need, an external GSM antenna can be used.
The electric power supply
The modem must be powered from an external power supply (a power supply adapter,
an accumulator battery). A power supply is connected to a supply terminal block. The
supply terminal block is a modem component. It is possible to use the power supply
adapter PS-ATM which is offered as optional equipment by the manufacturer.
The COM adapter IP65 ATXV-AC01X (for data loggers ATV/ATX)
The adapter is intended for the ATV or ATX data logger and the modem
interconnection via RS232 serial link. This adapter provides a communication between
the modem and the data logger. The length of the cable is cca. 160 centimeters.

8
Connection cable kit ATP-AC10 (for data loggers ATP)
The kit is intended for the ATP data logger and the modem interconnection. The kit
consists of two cables: the cable for the data logger and the modem interconnection via
RS232 serial link and the cable for voltage distribution between the data logger and the
modem. Two pieces of contact tubes are also included along with the cable for voltage
distribution.
The data logger
The data logger is a target device. The modem is intended for communication with this
device. Generally, the data logger types ATV, ATX and ATP are supported.
The paid version of program for data loggers ATXV-WIN
This program makes possible to change of modem settings, to communicate with the
data logger, to read information about actual settings and data logger status, to change
parameters for data recording and to read measured data. Minimal program version
must be 2.2.18.0. The latest program versions are available on www.atal.nl. A GPRS
connection or a setting cable (for example if the GPRS connection is not activated) can
be used for setting of the modem with this program.
The M2MTalk server service
If you want use SMS messages only, you will not have to activate this service. For
anything else (like remote communication with the data logger including data
downloading), this service must be activated. By default, this service is not activated by
manufacturer. In addition, if this service is used, GPRS must be activated on your SIM
card. Method and amount of payment for this service are determined by valid trading
conditions.
3.2. Additional accessories
The setting cable AT-AC-NULL
The cable is intended for setting of the modem with the program for data loggers (from
the computer) via RS232 serial link. It is needed for service purposes only, possibly for
local settings of the modem during its activation, for example if the GPRS connection is
not activated. Using of standard RS232 crossover cable as current computer equipment
is alternative variation. New computers are not equipped with serial COM port
generally. For solution of this problem, the converter AT-USB232 (RS232/USB) is
offered. It is plugged between computer USB port and the setting cable. After installing
included driver, a virtual serial port in the computer is created for communication with
the instrument.

9
The self-adhesive Dual Lock TRA-AC04
The industrial hook-and-loop fastener for easy installation of the modem on a flat
surface.
The modem wall holder GPRS-AC01
The modem wall holder includes 2 screws for mounting on the back side of the modem
and set of 2 pieces of wall plugs + 2 pieces of screws for mounting on the wall.
Attention! This type of mounting MAY NOT be used if the modem is operated in a
vehicle. The metal covering of the modem is conductively connected with negative pole
of power supply. Therefore, it cannot be conductively connected with a vehicle chassis
ground.
The modem DIN rail 35mm holder GPRS-AC02
The modem DIN rail 35 mm holders include 4 screws for mounting on the back side of
the modem.
Attention! This type of mounting MAY NOT be used if the modem is operated in a
vehicle. The metal covering of the modem is conductively connected with negative pole
of power supply. Therefore, it cannot be conductively connected with a vehicle chassis
ground.

4. Quick installation
4.1. Check of accessories
Make sure you have available all accessories needed to operation (the SIM card, the GSM antenna,
the power supply adapter and the COM adapter IP65 or the connection cable kit according to the
data logger, the data logger, the pay version of program for data loggers and access to the
M2MTalk server service, if you want to use it).
4.2. Software installation
Install the paid version of program for data loggers (minimally the version 2.2.18.0, see also the
page 7) on the computer, from what you want to have access to the device. The latest program
version is available on www.atal.nl. Please follow instructions of the installer during installation
process.
If you have activated GPRS data services, you will use the GPRS connection for setting of the
modem. In this case, installation of any others drivers is not needed.
If you want to set up the modem by using the setting cable via RS232 interface (for example when
you have not activated GPRS data services), you must also install driver for GPRS modem
configuration which is available on above web address too.
4.3. The modem assembling
4.3.1. The SIM card
You must have activated a GPRS data services if you want to communicate with the data logger
remotely via GPRS.
If the modem and the data logger are operated in a vehicle, it is necessary to have in mind that
mobile operators will be allowed to change while crossing borders of various countries. If you also
want to communicate with the data logger remotely via GPRS in a foreign network, you must have
activated GSM and GPRS roaming (data roaming) on your SIM card. Moreover, the GPRS
roaming contract must be concluded between home and foreign mobile operators. It is advisable to
ask the home mobile operator about it even before going abroad. When in use GPRS roaming
mode, GPRS transferring prices can be markedly higher than in the case of a home network!
A PIN code entering must be deactivated on the SIM card. Using the SIM card in any mobile
phone is the simplest method how to make sure that a PIN code entering is deactivated. If a
demand for entering a PIN code is displayed after switching the mobile phone on, you will have to
deactivate a PIN code entering. This procedure is dependent on a type of the mobile phone and it
should be described in a mobile phone’s user manual.
The SIM card is put in a holder. The holder is a modem component. The holder is ejected by
pressing the button beside the holder by using a fit instrument, for example a pencil. Insert the
prepared SIM card into the holder. See that the SIM card stays in alignment with the holder
correctly for all its size. After it, the holder with the inserted SIM card is pushed in the modem.
The correct way to install the SIM card is shown in the picture.

11
The way to install the SIM card
4.3.2. The GSM antenna
The GSM antenna must be mounted to the antenna connector by lightly tightening a sleeve nut.
4.3.3. Connecting the power supply to the modem
The power supply is connected on a WAGO terminal block which is a modem component. Insert a
flat-bladed screwdriver to rectangle terminal hole and push the screwdriver towards away from
you –the contact is released. Connect a wire to the released terminal and close the terminal by
removing the screwdriver. Connect positive pole of the terminal marked with + and negative pole
of the terminal marked with –. The correct way to connect wires is shown in the picture given
below.
Way to connect wires
The entire terminal block is possible to remove from the modem by pulling it up from the
connector.

12
In the case of using the power supply adapter PS-ATM, connect the white wire to positive pole and
the black wire to negative pole.
Connecting of power supply adapter PS-ATM
If the modem and the data logger ATP are operated in a vehicle, it will be necessary to use the
cable for voltage distribution between the data logger and the modem. For more detailed
information see the chapter The data logger and the modem interconnection on page 12.
4.3.4. The data logger and the modem interconnection
The ATV or ATX data logger and the modem interconnection is provided with the COM adapter
IP65. Connect the adapter connector to the RS232 connector on the modem and plug the adapter to
the guide slots on the side of the data logger. Heed to keep a minimum distance between the
modem antenna and the data logger during installation to prevent the data logger interference. This
distance may not be in any case less than 50 centimeters. Keeping the distance at least 1 meter is
recommended. The correct way to connect is shown in the picture given below.
The ATV or ATX data logger, the modem and other accessories interconnection

13
The ATP data logger and the modem interconnection is provided with the connection cable kit
ATP-AC10.
Attention! The metal covering of the modem is conductively connected with negative
pole of power supply. Therefore, it cannot be conductively connected with a vehicle
chassis ground. Use the self-adhesive Dual Lock TRA-AC04 for mounting of the modem
on a vehicle.
The cable for voltage distribution between the data logger and the modem must be cut to proper
length. Strip the insulation from the end of the wires and twine it with separated insulated
conductors of the supply line. Be careful of the polarity. The supplied contact tubes must be forced
on the pairs of twisted stripped wires. This preassembled set must be connected to a supply
terminal block of the data logger. On the modem side, the contact tubes were already forced on the
wires at the factory. The correct way to connect wires for the feeder cable is shown in the table
given below.

4.4. Switching on the modem
The properly assembled modem is switched on by feeding of electric voltage into the modem
supply terminal block. The green LED diode lights up. The modem will be prepared for
communication after ca. 1 minute from its switching on. It is advisable to check the
communication by sending SMS message gsmstatus to the modem phone number. A response
delivery time is generally dependent on a momentary cellular network load and state. If the modem
works correctly, it will send back SMS message with its state information. If you don’t receive the
response to this SMS message, please check your SIM card settings, power supply connection and
aerial connection.
If communication with the modem via cellular network is impossible, you can try to find a
problem with the program for data loggers. In this case, you must interconnect the modem and the
computer via the setting cable, see the chapter The setting cable AT-AC-NULL on page 8.
4.5. Setting up the modem
If you don’t intend to use remote communication with the data logger via GPRS, you can go to the
chapter Setting of the other parameters on page 15.
4.5.1. Setting of GPRS connection parameters
If you didn’t specify the GPRS connection parameters before ordering the modem, you must set it
up now.
To do it, you can send a special SMS message to the modem phone number. The first word of the
message must always be gprs. After this keyword, parameter values for an actual setting follows in
specific order (see below):
gprs [apn] [user] [password] [dns]
If the trailing parameter values are not entered, they will be deleted. Don’t enter the square
brackets in the SMS message. Individual items of the message must be separated by spaces. For
more detailed information about setting this parameter values via SMS command see the chapter
Setting of the GPRS connection on page 20.
The example: You can set up the parameter apn to value internet without other parameters (user,
password and dns) by sending the SMS message
gprs internet
For getting information about GPRS connection parameters please contact an appropriate mobile
operator.
4.5.2. Setting of M2MTalk client parameters
These parameters are already preset at the factory, don’t change it gratuitously! If you can verify a
setting, compare it with data listed in the card which was delivered with the modem.
M2MTalk client parameters can be set via the SMS command (see the chapter Setting of the
M2MTalk server connection on page 22) or via the setting cable (see the chapter Setting of the
modem using the setting cable on page 35).

15
4.6. Login the modem on the M2MTalk server
If you intend to use remote communication with the modem or data logger via GPRS (for example
to set up this device remotely), the modem always must be logged on the M2Mtalk server before
starting the communication. The modem can be set up to login on the server automatically after its
switching on, but it isn’t a standard factory setting.
To login the modem on the M2MTalk server, you can send a SMS message login to the modem
phone number. The modem will send back an acknowledge SMS message. It is advisable to check
the login status by sending SMS message gsmstatus to the modem phone number. If the modem
works correctly, it will send back SMS message with information. The login status is also
including in these information (M2MTalk online: yes).
Attention! Since the modem is logged on, a limited data transferring also proceeds in
case the remote communication with the device isn’t in progress (due to keeping the
connection). Transferred data is charged as per your GPRS tariff by the mobile operator.
Around 26 kB of data per day are transferred for keeping connection purposes. If the full
up data logger memory is about to be downloaded, around 73 kB of data per day are
transfered for data loggers ATV/ATX and around 1162 kB of data per day are transfered
for data loggers ATP. Logout from the server is described in the chapter Logout from the
M2MTalk server on page 19.
4.7. Setting of the other parameters
The information that the alarm is active and information about correct operation of the data logger
can be periodically taken from the data logger by the modem. These informations are processed
and then the modem sends alarm SMS messages to a customer according to these analyses.
The program for data loggers is used for setting of these parameters. If GPRS connection isn‘t
activated, you will have to set up the modem by using the setting cable.
There are these parameters:
data logger reading interval, see the chapter 6.1 on page 29
sending / no sending of the warning SMS messages, see the chapter 6.1 on page 29
phone numbers for the warning SMS messages recipients, see the chapter 6.1 on
page 29
phone numbers, from which the incoming SMS messages will be accepted by the
modem, see the chapter 6.1 on page 29
setting of the alarm conditions for the data logger if this functionality is required,
see the chapter 6.2 on page 35

16
5. Communication via SMS messages
It is possible to control and monitor the device operation remotely via the special SMS messages,
which are being sent to the modem phone number. The user can select phone numbers, from which
the SMS messages are accepted by the modem. The factory configuration doesn’t restrict the
phone numbers for any incoming SMS messages that means any SMS messages are accepted
regardless of the sender phone number. Phone numbers restriction can be done with the program
for data loggers, see the chapter Settings of the program for data loggers to use it with the modem
on page 29.
Generally, SMS command messages aren’t case sensitive and the space serves as a parameter
separator.
If the accepted command isn’t supported or it hasn’t a correct syntax or parameters, the modem
will send back an SMS message with a proper error description. This information will be returned
only three times in maximum. The fourth and every next incorrect command from the one phone
number is ignored until the incoming command will be correct again.
5.1. The query SMS messages
Using these messages, you can take the current measured values from the connected data logger,
the modem firmware version and the current modem state information.
5.1.1. The query about the current values
To take the current measured values from the connected data logger, send the SMS message values
to the modem.
If a data logger ATV or ATX is connected to the modem, it will send back a SMS message with
the following contents:
data logger identification –the user’s description of the data logger is displayed. If
this description isn’t set, the serial number of the data logger will be displayed. If the
total message length would exceed 160 characters, the serial number of the data
logger will be displayed instead of the description.
measured values of single quantities –the channel number or channel description (if
it is set) is displayed, the measured value and the quantity unit follow.
The response message example:
Logger Store_13: Temp: 24.7C Hum: 45.5%RH DP: 12.1C
If a data logger ATP is connected to the modem, it will send back a SMS message with the
following contents:
data logger location –the user’s description of the data logger location is displayed.
If this description isn’t set, the serial number of the data logger will be displayed. If
the total message length would exceed 160 characters, the serial number of the data
logger will be displayed instead of the description.

17
measured values of single quantities and current binary inputs states –the channel
number or channel description (if it is set) is displayed. If a measured quantity is
assigned to the channel, the measured value and the quantity unit will follow. If a
binary input is assigned to the channel, the user’s description of the current binary
input state will be displayed.
The response message example:
Logger Store_13: Temp1: 24.7C Temp2: 25.0C Bin1: OFF Bin2: ON
If it is not possible to take information about the values, i.e. the data logger is switched off, a
communication error between the modem and the data logger has occurred or detecting of the data
logger type is in progress, the modem will send back a SMS message with a proper error
description.

5.1.2. The query about the current values and their alarm settings
To take the current values from the connected data logger and their alarm settings, send the SMS
message values! to the modem. The content of the response message is similar to a query values.
Moreover, if the measured value exceeds any alarm limit or if the binary input is in a state of active
alarm, the symbol „!“ will be displayed in front of the value. This response message also includes
alarm limits for measured values (but not for binary inputs). If a data logger ATP is connected to
the modem, information about adjusted alarm delays in minutes for all measured values and binary
inputs will be displayed too.
The response message example (data logger ATV or ATX):
Logger Store_13: Temp: 24.7C 19.0..26.0 Hum: 45.5%RH 0.0..50.0 DP: !12.1C 0.0..10.0
