1. Main features
GPRS Tau is a communication device with the main purpose to transmit data from security
panels and/or sensors through GPRS and/or IP based network. Combining the advantages of
those two advanced communication technologies GPRS Tau provides the most secure
connection with monitoring center.
Features:
Power supply 12VDC (8,5V to 16V)
Low power consumption
Capability to use communicator as input -
using “Ademco Contact ID” protocol
Six digital inputs working simultaneously
with GPRS and/or IP transmitters
HTML server for easy configuration and
status check, protected with an username
and a password
Easy configuration without the need of
specialized software for programming -
using only a web browser ( Internet
Explorer, Google Chrome, Firefox etc. )
Capability to use one or two fully
independent servers. Additional option to
use GPRS only as a backup in case the IP
network fails
SMS report of the status of the
communicator and/or digital inputs to up
to 5 mobile numbers

Capability every digital input separately to be set to transmit SMS report
PGM output controlled by SMS or call
Capability to enter PIN or PUK code for the SIM card
Graphical display of the status of the GPRS network in the web interface
Encrypted connection with IP servers
Verification with an unique ID code
Capability to change the username and password of the html server
Indication (4 LEDs) for:
LAN Status - Ethernet available
LAN Activity - Network packets service
GPRS LED –‘ON’ when connected to GPRS network
Server LED - Established connection with server/s –when using 1 server - ‘ON’ when connection is
established. When using 2 servers - ‘ON’ when connection is established with both servers, blinks if
connection is established with only one server , ‘OFF’ when connection isn’t established with both
servers
Configurable working mode for every digital input:
Normal Open
Normal Close
Check for AC voltage from 5V to 20V
Deactivated
Configurable parameters sent for events on each digital input to IP servers

2. Start working with GPRS Tau
The default IP address is 192.168.1.230. Make sure that your computer is in the same IP
subnet ( see Chapter 10. Windows Network configuration). To access the web server for
configuration use Internet Explorer ( Chrome, Firefox, Opera or any other web browser ) and
enter the GPRS Tau’s address - http://192.168.1.230/ ( or the new one if you already change it
). Alternatively you could write http://gprstau. If the device is accessible from that computer a
connection will be established and you will be prompt to enter username and password:
The default settings (which will be recovered after hardware reset ) are:
IP Address: 192.168.1.230
Username: root
Password: admin
If you enter the right credentials you will have access to the web page for configuration.

input voltage, last 5 messages received from the communicator, current state of each digital
input, PGM state, GPRS status information about the operator and the signal strength. Through
the menu you could select one of the following actions:
Home –Homepage
Device Config –Configuration of the main parameters
Login Config –Configuration of username and password for web-server access
Utility –Test the connection to the servers
About –Contact information

4. Configuration of the main parameters
4.1. General settings
Device Name –Enter the name of the device. This value is used only for user convenience
–to identify devices if you have more than one connected to one network. Maximum length –
30 symbols.
Select working mode and protocol:
Protocol –The device can use either Ademco Contact ID or LARS protocol. When using
Ademco Contact ID the device can receive data from communicator/dialer.
Account Number –Site’s number.
If working with LARS protocol - first three symbols must range 0 to 7 and the last symbol
must range 0 to 9 or A to J. In the monitoring software, the last symbol can be set as a digit or
letter ( the digits 0 to 9 correspond to the letters A to J ).
If working with Ademco Contact ID protocol –each of the four symbols must be from 0 to
9 and/or from B to F.
System –System number –must range 0 to 3. It is used only when the device works on
LARS protocol.
Communicator –When the device works on Ademco Contact ID protocol, the sixth input
can be used as an input for communicator/dialer on Ademco Contact ID protocol. The phone
number that should be set in the security control panel is - 9.
Handshake Delay –Ademco Contact ID specific timing. It sets the delay between the
phone number dial and the Handshake tones. Default value is –16.
Send message if DC is lower than 10V –Option that enables/disables generating of
message if the input voltage drops under 10V.

4.2. General IP settings
IP settings:
Obtain an IP address automatically via DHCP –IP address is received automatically from a
DHCP server in the current network. If you select this mode but after reboot the device cannot
find a dhcp server for more than 10 seconds –GPRS Tau will load the last saved static address.
In this case easy way to access the web-server is by entering the following address:
http://gprstau
Use the following IP address –IP address and network parameters are set to static
IP Address –IP address
Gateway –Gateway address.
Subnet Mask –Subnet mask of the IP network.

4.3. Server settings
GPRS Tau can work with two independent IP servers. The first group is corresponding to
the first monitoring server. The field - Type - sets the type of communication which must be
used to connect to the server - IP network, GPRS network, IP network if available and GPRS as
a backup if IP fails. This option is a good way to minimize the GPRS traffic. IP address and the
communication UDP port must be set. Periodic test can be activated by selecting the checkbox
Use Periodic Test on Server 1 and then setting the test period. Also a backup server can be
enabled by selecting Use Backup Server. If the server on the primary IP address and UDP port
fails –the device will try to send data to the backup IP address and UDP port.
If you want to use the second server you must enable it - Enable Server 2 –and to set the
parameters in the same way as for Server1.
