Domino
DFGSMIII
DFGSMIII: GSM module for remote
control
DFGSMIII module allows to receive information from a
Domino bus and to send commands using a standard GSM
portable phone.
The way to exchange information with the Domino bus is
based upon the SMS messages (Short Message Service :
each sent/received message contains literal strings fully
configurable by the user.
In comparison to similar systems based on DTMF tones,
DFGSMIII module allows to exclude any misunderstanding
about the sent commands and to have clear and explicit in-
formation about the status of the system.
DFGSMIII contains a “GSM engine” that may operate both
with rechargeable and contract SIM cards.
The main features of DFGSMIII module are the following:
➢Enabled telephone numbers: up to 32 telephone
numbers may be defined, from which accept SMS to
perform commands or to which send information SMS.
➢Jolly number: the “jolly number” function allows to a
not listed user to send a command SMS to DFGSMIII
module, of course provided that before the commands
a well defined password has been inserted.
This password must be always inserted at the begin-
ning of SMS and can be freely set using the support
software DFGSMTools.
➢SMS from DFGSMIII to user: up to 64 SMS may be
defined, that DFGSMIII module will send to one or
more phone numbers at the occurrence of an event
(e.g. alarm system, failure of the boiler, etc. ; each one
of these SMS can contain information about one or
more points of Domino bus or about the local input of
the module.
➢SMS from DFGSMIII to user at interruption and
restoring of the power supply: thanks to an internal
rechargeable battery, DFGSMIII may be set to send a
message at the interruption and/or at the restoring of
the power supply; these two messages may be defined
by the user and they may be individually enabled.
This feature does not depend on the bus activity and it
is useful to be informed about the status of the electric-
al network at home. At the interruption of the power
supply, DFGSMIII module will be automatically
switched off after a programmable delay; during this
time the local inputs are still working.
➢SMS from DFGSMIII to user at
Domino
bus failure:
DFGSMIII can be set to send a message at the occur-
rence of Domino bus failure and/or at its restoring
➢Forwarding of SMS from DFGSMIII to user: DFGS-
MIII can be set to forward all SMS, received from not
listed phone numbers, to one of the listed phone num-
bers, or to a number not inserted in the user list.
➢SMS from user to DFGSMIII for command execu-
tion: up to 64 “command strings” may be defined;
each string can execute up to three different actions.
Sending a SMS containing one or more of these
strings, DFGSMIII module will execute the specified
commands, but provided that the SMS has been sent
from an listed phone numbers (or from the jolly num-
ber . Between the processing of a command string and
the next one, the module waits for a pause of 1
second. If a command string is set to perform more ac-
tions, these ones will be processed without any pause,
so they will be executed almost at the same time. For
each command string, at least one action must be
defined.
➢SMS from user to DFGSMIII for information re-
quest: the command SMS described at previous point
may contain also a request of SMS sending to the
user, reporting information about one or more points of
the system.
➢SMS from user to DFGSMIII for remaining credit
request: after proper setting, it is possible to send a
SMS to force the request of the remaining credit from
DFGSMIII to the mobile service provider when using
prepaid SIM.
➢Execution of commands by a oice call: “voice call”
is a standard call from any telephone (GSM or wired ; if
the calling number is among the enabled ones, then
DFGSMIII module will reject the calling after a pair of
rings without answer to it and it will execute the com-
mands (if enabled configured for that phone number.
This feature allows to execute some commands at zero
cost because DFGSMIII, as said, does not answer to
the voice call
➢Local inputs and outputs: DFGSMIII provides 8 in-
puts, 2 relay outputs (with floating contacts and 2 NPN
outputs, absolutely independent from the Domino bus;
these points may be used to acquire status and to ex-
ecute commands regardless of the bus activity.
➢Log on SDCARD: DFGSMIII performs a daily record-
ing (log on SDCARD, storing all the significant events
occurred during the day.
➢Management of PIN and PUK code by the PC: it is
possible to enable/disable the PIN code of the SIM by
using DFGSMTools programs, avoiding the need to
use a third GSM phone. In addition, by PC again, it is
possible to change the PIN code of the SIM.
