Universal GSM Communicators
The GD-06 is a universal device for sending
information, data collection and in-house app-
liance or process control. It can communicate
through SMS messages, GPRS data and direct
control from any phone by DTMF commands. It
is possible to monitor the status of the GD-06,
set its parameters and control outputs very
conveniently from the secure internet web site
www.GSMLink.cz. The GD-06 has 6 fully programmable ports (inputs/outputs) and an output relay. A temperature
sensor is integrated too. During input activation it transmits information by SMS, voice calls, or GPRS data. It is
possible to choose digital or analogue input reading modes. Outputs are able to be controlled by calling from
pre-defined phone numbers, by SMS messages, by DTMF commands or via the GSMLink web site. Outputs can be
switched as latches for pre-defined times (impulse mode) or be triggered by the internal temperature sensor.

GD-06 ALLEGRO GSM Universal Communicator
The GD-04 DAViD has a function of a multi
channel universal GSM communicator and con-
troller. It has four inputs (A, B, C a D) and two
relays outputs (X and Y) with contacts load
5 A/250 V. Those two relays can be operated
by SMS commands or by unanswered phone
calls from authorized numbers for free (up to
50 numbers can be set for each relay). While
setting the authorized number for operating
with a phone call, you can also set the limit of
operating phone calls and when it is reached
DAViD ignores any phone call coming from that
number. This function is suitable for any pre-
paid service (e.g. number of uses of the parking lot etc). The output switching time can be set from 1 second to
10 hours. Activation and deactivation of the inputs can be reported by preset SMS message (or by a phone call
as well) to up to 8 phone numbers. Inputs recognize opening and closing of the contact and can send different
messages when the contact is opened or closed. The text report can be supported by a phone call as well to all
the numbers to which SMS messages were sent.
The GD-04 DAViD can be extended with many extension modules. The GD-04R radio module enables input acti-
vation (A to D) by wireless buttons and detectors from the Oasis system. Relays X and Y in DAViD can be locally
operated by RC-8x wireless buttons (that means that a connected device can be operated by mobile phone and
by remote controller as well). DAViD can also report on the state of its output relays (X and Y) to UC and AC
wireless receivers. A heating system can be operated (locally or remotely via mobile phone) in cooperation with
TP-8x wireless thermostats. A GD-04D DTMF module enables the operating of DAViD’s output relays by a phone
call and numeral code entry on a phone keypad. The GD-04A backup battery provides approximately 12 to 24
hours backup time in cases of power failure.
DAViD can be set by programming SMS messages or by using GDLink software from a computer or just by filling
in a simple form on www.david.jablotron.com. The GD-04P connecting cable is necessary for setting up DAViD
from a PC via GDLink software.
