1 Main function of the Adapter
The main function of the GPRS Adapter is to forward alarm control panel signals to the
monitoring station using GSM / GPRS connection.
2 System operation
To transfer signals, the GPRS Adapter uses primarily GPRS communication, but in case
this is not available for the moment it communicates with the switched line receiver (e.g.
Enigma) of the monitoring station through GSM voice call:
3
2.1
Transmission through GPRS
The GPRS Adapter keeps the connection primarily using GPRS data communication: it
communicates with the TEX server (with the first one available, in case of using more
servers) using the GPRS network, through the APN centre of the GSM provider, then
through the internet and then through the router of the monitoring station. After
conversion, the server transfers the received packages to the monitoring PC through
serial port.
The serial communication between the server and the monitoring PC is realized with the
same protocol that is used by switched line receivers, therefore any monitoring software
can be used on the monitoring PC, even the one used previously in case it handles
Contact ID communication format (e.g. AlarmSys).
2.1.1 Router settings
For the functionality of the system, it is necessary to perform the following settings on
the router:
• When using DHCP, take care that the local IP address of the server should not
fall into the DHCP range.
• The public GPRS device communication port (default: 3333) has to be forwarded to
the local IP address of the server, to port 3333 and has to be always enabled
• The public WEB event log port (default: 8280) has to be forwarded to the local IP
address of the server, to port 8280 and has to be always enabled
• The public upgrade port (default: 22) has to be forwarded to the local IP address of
the server, to port 22 and has to be enabled only when requested by the
manufacturer with upgrading or diagnostics purpose.
4
2.2
Transmission in reserve GPRS mode
In case the server (or any of the servers, if using more than one) is not operating or
cannot be accessed through the internet because of failure or maintenance, the GPRS
Adapter connects and communicates with the Backup server. The Backup server placed
in a distant server hotel is connected to the Backup PC using landline or wireless (GPRS
with HSDPA modem) internet connection. For security reasons it is recommended the
use of the wireless internet, in case the landline internet is not independent from the one
used by the primary servers.
Maintenance of the connection and the forwarding of the data received from the Backup
server to the physical serial port is performed by the GPRS COM Port software, installed
and started previously on the Backup PC.
Insertion of the Backup PC is not obligatory, but it is strongly recommended to avoid the
direct exposition of the monitoring PC to eventual attacks coming from the internet.
In case the Backup PC is not used, then to maintain the continuous internet connection
use the GPRS VPORT software (on the monitoring PC) instead of the GPRS COM Port
software.
The Backup PC should be an office machine, capable to use Windows XP or Windows
Vista operating system.
The Backup PC has to be connected to a free serial port of the monitoring PC using a
null modem cable (in case there is no free serial port, the monitoring PC is necessary to
be expanded).
The monitoring software receives the signals using this serial port.
For the independent internet connection of the Backup PC can be a good solution the
mobile internet package of any GSM service provider. These packages contain a
wireless internet modem that can be quickly and easily installed and used on USB port
with Windows operating system.
You can also calculate with almost 100Mbyte data traffic due to the frequent connection
controlling communication between the Backup PC and the Backup server, consider this
too when choosing the GPRS internet package.
5
2.2.1 Setup „GPRS_COM.exe”
In case of using distant Backup server, the „GPRS COM” software is necessary to run
on the Backup PC. This software maintains the connection with the distant Backup
server, takes over the Contact ID signals appearing there and forwards them to the
serial port of the monitoring PC.
• Start the „GPRS_COM.exe” software (found on CD enclosed or can be
downloaded from www.tell.hu web site)
• Connect Backup PC and Monitoring station client PC with serial Null-modem cable
• Select the physical serial port (where the cable has been connected) and open it
by clicking on "Open serial port" button
• Enter the access password for the server. The password is sufficient to be entered
at first start.
• Click on "Details >>>" button then click on "Connect to Server" in the new window
• Check whether the connection to the server has established (green icon)
• Set the serial port parameters in the monitoring program according to „Setting
serial port connection” chapter
• When serial port connection is established, the Backup PC will receive the
incoming Contact-ID messages through the internet and will forward them through
serial cable (the same way as a standard PSTN receiver) towards the monitoring
station client PC. The monitoring program will display and log the received
Contact-ID messages.
• Turn off "auto-answer for debug" option in the GPRS COM Port software when
using a monitoring software, else it will acknowledge all incoming messages itself,
even if the monitoring software does not acknowledge!
This function serves only for testing and troubleshooting!
It is possible to automatize the software startup and running with command line
parameters by placing a parameterized shortcut in the startup as follows:
-com=ordinal number
setting the ordinal number of the COM port
-ip=IP address
setting the IP address of the server
-m
minimize to tray icon on startup
-s0
no save of the specified parameters in the .ini file
-a
open serial port and connect to server automatically
6
The program first loads the content of the .ini file as default setting, then modifies the
settings with the parameters specified in the command line.
For automatic startup the .ini file has to contain already the access password to the
server. For this set the password in the program, click "Yes" to save it, then close the
application. This way the password will be saved in the .ini file in a coded format.
Example of use:
GPRS_COM.exe -com=4 -ip=193.28.86.102 -m -s0 –a
The use of GPRS VPORT program is similar to GPRS COM Port, the difference is that
the VPORT program runs on the same PC as the monitoring software and the
communication between them is performed through the virtual serial port created by the
VPORT program.
2.3
Transmission when GPRS connection fails
When the GPRS Adapter is unable to establish GPRS data connection with any of the
servers, then it communicates with the switched line receiver of the monitoring station
using GSM voice call.
In case of transmission through GSM voice call, respectively if the device that receives
the signals on the switched line receiver's side is a GSM Adapter, an increased signal
delay can be expected.
This delay is varying, estimated between 50-400ms.
This means that due to the GSM network delay it will be probably necessary to modify
the timings on the receiver that has originally been designed for landline.
Due to this it may happen that after the receiver acknowledges a Contact ID signal will
wait for the following Contact ID signal only for the time defined by the standard.
However, in case of transmission through GSM the acknowledgement signal emitted to
the respective Contact ID signal will be received by the alarm control panel with the
delay of the GSM network, then the following Contact ID signal launched to this effect
will also be received with delay by the monitoring station.
Improper setting or the use of an outdated receiver that cannot be parameterized, may
cause hang-up of the line by the receiver before receiving the newer signal.
To avoid possible technical problems and to assure performance of the necessary
settings please contact the manufacturer of the given receiver.

3 Monitoring software settings
3.1
Setting serial port connection
In the monitoring program serial connection should be set as follows:
• Baud Rate: 9600
• Data bits: 8
• Parity:
No
• Stop bits: 1
e.g. in Alarm-Sys
software:
3.2
Event code settings
Events and Contact ID codes generated by the GPRS server:
Contact-ID code
E361
E362
E363
R361
R362
R363
Event
Internet1 connection failure
Internet2 connection failure
LAN connection failure
Internet1 connection restored
Internet2 connection restored
LAN connection restored
The server transmits the restoration events as well. e.g: E361, when internet1
connection failure occurs, then R361 when connection restores.
In some monitoring software E (new event) is 1 and R (event restoration) is 3.
The user ID of the server towards the monitoring software is: 9999
Events and Contact ID codes generated by the GPRS server, but transmitted with the
user ID set in the GPRS device:
Contact-ID code
Event
E360
GPRS test report timeout
R360
GPRS test report restored
8
After connecting to the server, the GPRS device informs the server about the set GPRS
test report timing and user ID, respectively sends the first GPRS test report (alive test
signal).
When the server detects that the set GPRS test report timing has expired since the last
test report, waits 3 minutes and if it does not receive test report during this, it generates
the GPRS test report timeout message with the E360 Contact ID code and with the user
ID set in the GPRS device. For easier identification, the events can be named according
to the above tables in the monitoring software (e.g. in AlarmSys software):

Parameter settings
In this window saved settings can be loaded from files, saved to files or loaded to or

5.5.1 Monitoring settings
In this window monitoring station settings can be performed.
Operation in case of GPRS connection fault:
„Secondary reporting method in case of GPRS fault”
The following three processes will be performed independently from any settings:
1. If there is no GSM network available but there is an alive PSTN line, it immediately
switches to PSTN line
2. If GSM network is available but the module still tries to find an available server and
there is an alive PSTN line connected, then it switches to PSTN till finding a server.
3. If the server is found and connection is established, it immediately disconnects from
PSTN line (if existed).
(The call in progress can be interrupted, however it does not cause any message
loss, because the alarm control panel will repeat the unconfirmed events.)
In case „Report all events through GSM voice call” is selected:
If GSM network is available and tried to access all servers without success, then it
switches to GSM voice call, that is it interrupts the PSTN connection if existed. (The
call in progress can be interrupted, however it does not cause any message loss,
because the alarm control panel will repeat the unconfirmed events.)
17
In case „Report through GSM voice call only the events listed below ” is selected:
If GSM network is available and tried to access all servers without success, then it
emits the handshake and acknowledges all events (these will be lost) up to the point
until it finds one that is in the list. If it finds an event that is in the list, it will not
acknowledge it, and at the next dial the monitoring station will be notified through
GSM voice call. The event codes in the list must consist of 4 hexadecimal digits
each, where the first digit makes the difference between new event ("1") and
restoration event ("3").
When entering event codes in the list, code groups can be specified as well with the
use of "¾" character within the codes. This means it is indifferent what character is
received from the alarm control panel in the place substituted with "¾" character but
the rest of the code corresponds to the one in the list, the relevant event will be
transmitted.
In case of selecting „Don’t use GSM voice call, use PSTN if available”, only the first
three processes will be fulfilled.
In „Central station’s phone number” field enter the monitoring station’s telephone
number (which the alarm control panel will dial) in a form the number can be
successfully dialed from a mobile phone as well. The module will monitor the line and
when the alarm control panel dials this number, the module responds itself and
simulates a monitoring station. If no PSTN line is used, leave this telephone number field
blank and enter 0123 instead of monitoring station number into the alarm control panel.
The module will always react when the alarm control panel will dial 0123.
5.5.2 Stand-alone CID reports
In this window events sent directly by the module can be configured.
18
"User ID": has to be the same as the user ID set in the alarm control panel
"Contact-ID event codes":
• "IN1 contact": If input IN1 is activated, an event with the specified event code will
be generated by the module. By default this input is set NO (normally open), but
can be set to NC as well by enabling „IN1 is normally closed (NC)” option. It is
also possible to report the restoration of the input by enabling „Report IN1 restore
as well” option.
• "PSTN fault": in case of PSTN fault an event with the code specified here will be
generated by the module. If no PSTN line is used, leave this field blank.
5.5.3 BELL 103
The module is able to receive data calls initiated by GSM modems (T.E.L.L. GT64 is
recommended), through which the connected alarm control panel becomes remote
programmable (BELL 103/V.21 format). Concerning remote programming, the list of
supported alarm control panels can be viewed on www.tell.hu website.
In this window the management of incoming GSM data calls can be configured. The
setting provides possibility of limitation of incoming data calls to specified phone
numbers. If phone number filtering is selected, the module rejects all incoming GSM
data calls which are not initiated from the specified phone numbers.
When settings are done, load the data to the module using the PC->Microchip button.
19
5.6
View event log on the GPRS server's web site
The GPRS server's event log can be displayed with an internet browser (Internet
Explorer is recommended) in the following manner: if the fixed IP address on which the
GPRS server can be accessed from outside is e.g. 195.196.197.198, then the following
address has to be entered in the browser:
http://195.196.197.198:8280
The server requests the access code, which can be found on the printed GPRS
Datasheet supplied with the system and on the CD enclosed, in the CODES.TXT file
(e.g. 2FEB-CADE-32D4-EG68-4F11):
After entering the valid access code, the browser downloads the event log from the
server for the last 24 hours:
In each row an event logged by the server can be seen, with the following details:
• Date: event's date (yyyy-mm-dd) and time (hh:mm:ss)
• Module name: event's source (TEX Server or Serial Module that is a module also
running on the server, performing the serial communication)
• Category:
o Info: information (e.g. incoming Contact ID message)
o Successful: the Contact ID message has been successfully delivered to the
monitoring software
o Warning: e.g. GPRS test report absence or re-establish warning
o Failed: the Contact ID message delivery to the monitoring software has failed
• Client ID: monitoring station identifier/GPRS device identifier serial number
• Event: event description, the following messages can figure in square brackets: event
details e.g. characters of the Contact ID message, IP address etc.
On the top of the event list, in the field next to "Client ID" can be entered the last three
characters of the serial number of a GPRS device (e.g. 815 for device 0815, as it figures
in the list). This way the list can be filtered to that specific device after pressing the
"Reload Page" button.
20
In the field next to "Hours" can be specified how many hours of events to be displayed
retrospectively in the list, after pressing the "Reload Page" button.
To turn off filtering (display all events) clear the "Client ID" field then press "Reload Page"
button.
To exit and return to login page press "Logout" button.
5.7
Setup alarm control panel
• Contact-ID communication format has to be set in the alarm control panel
connected to the module
• The monitoring station’s telephone number (which the alarm control panel will dial)
has to be set in the „MINI_GPRS_Prog” program on „Central station’s phone
number” page. The module will react to this number.
• If no PSTN line is used and signaling through GSM voice call is not necessary as
backup possibility, then it is not necessary to enter a monitoring station telephone
number in the module and it reacts when the alarm control panel dials 0123. In this
case it is sufficient to set 0123 as monitoring station phone number in the alarm
control panel.

7 Installation guide
Before installation verify the future environment of the Adapter:
• Check the GSM signal strength using your mobile phone. It may happen that the
signal strength is not sufficient in the desired installation place. In this case you
have possibility to change the planned installation place before mounting.
• Do not mount the unit in places where it can be affected by strong electromagnetic
disturbances (e.g. near electric motors, etc.).
• Do not mount the unit in wet places or places with high degree of humidity.
7.1
Mounting
Suggested installation method: the GPRS Adapter should be placed into the same metal
housing as the alarm control panel. Drill a hole on the metal housing for the FME
connector. Choose the drill size appropriate for the FME base part. Fix the FME base
with the enclosed screw nuts into the housing. Ensure that the FME base and the metal
housing has galvanic connection.
In case of plastic housing and weak GSM signal strength it may be necessary to use
another (directed) type of antenna.
7.2
Putting into operation
•
•
•
•
Make sure the SIM card is placed into its case properly.
Make sure the antenna is fixed in the Adapter properly.
Make sure the wiring is done as earlier instructed.
The device can be powered up (9-24V DC). Make sure that the power source is
sufficient at the load of both the alarm control panel and the Adapter. The
quiescent current of the Adapter is 100mA, however it can reach up to 500mA
during communication.
