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.

SIM card and battery
To insert the SIM card remove the front panel. The SIM
holder is clearly visible and it is exactly on the GSM engine.
The SIM card must be inserted with the electrical contacts
oriented toward the bottom side.
Under the front panel is also located a jumper allowing to
connect/disconnect the Li-Ion battery. To avoid the battery
discharge, the module is provided with the jumper un-
plugged; the installer, during the setting up, has to plug the
jumper as in the following figure.
Address programming
DFGSMIII must be set by the support program DFGS-
MTools so that to define the several parameters needed for
its proper operation; for more details refer to the pro-
gramming manual.
DFGSMIII module takes, inside the Domino bus, 4 con-
secuti e input addresses, each one providing 16 digital
points to be used to perform the commands on the real or
virtual output module of the system. In other words, up to 4
x 16 = 64 input points are available; these inputs, instead to
be connected to “physical contacts”, are driven by the in-
coming messages (SMS to DFGSMIII module. These
points will be therefore used to perform the desired actions
through a proper programming of the Domino system. The
support program DFGSMTools allows to define the starting
address of DFGSMIII module. No output address are
used by this module.
Note: it is not possible to assign the address of DFGS-
MIII neither by the program BDTools nor by DFPRO pro-
grammer.
A white label on the front panel of DFGSMIII allows to write
the starting address assigned to the module for an immedi-
ate visual identification. The housing is a standard 6M box
for DIN rail.
Wiring diagram
A 2-pole terminal block on the top side of DFGSMIII mod-
ule allows the connection to the Domino bus; DFGSMIII re-
quires a 12 ÷ 24V dc power supply or a 12V~ trans-
former (not provided connected to SUPPLY terminal block
(on the right side of the bus terminal block .
A special connector on the top right side allow the connec-
tion to the antenna (provided . The antenna must be placed
in order to allow a good reception of the GSM signal. The
micro SD card is located on the top side, on the left of the
antenna connector; this SD card is provided together the
module, already inserted and properly configured, therefore
it must not be removed from is holder for any reason, on
the contrary the warranty will expire.
On the bottom left side the module provides: a 4-way ter-
minal block providing 2 potential free contacts (O1 and O2
and a 3-way terminal block for the connection of 2 external
relays (O3 and O4 ; the coil of these relays must be rated
12V or 24V dc current, depending on the voltage applied to
the SUPPLY terminal block (see connection diagram .
Another 9-way terminal block on the bottom right side of
the module allows the connection to the local inputs that
must be potential free.

Meaning of the LEDs on front panel
A small USB connector for the connection of DFGSMIII to
the PC is located on the front panel. The red LED located
on the top of this connector reports the communication
activity between the PC and the module itself. During the
communication this LED will flash showing the information
exchange.
In addition to this USB communication LED, the following
ones are placed on the front panel:
➢LED Init
➢LED Field
➢LED SMS IN
➢LED SMS OUT
➢LED Power (ON)
The following table shows the possible combinations of the
LEDs signalling. Fourteen different situations can be identi-
fied as listed in the following table. “FF” means “Fast
Flash”, while “SF” means “Slow Flash”. Of course “ON”
means that the related LED is fixed ON and “OFF” means
that the related LED is OFF.
Init Field SMS IN SMS OUT ON USB
1 FF OFF OFF OFF ON OFF
2 SF OFF OFF OFF ON OFF
3ON ON OFF OFF OFF OFF
4ON OFF OFF OFF ON OFF
5ON ON ON ON ON OFF
6ON OFF OFF ON ON OFF
7ON OFF ON ON ON OFF
8ON OFF SF SF ON OFF
9ON OFF FF FF ON OFF
10 OFF SF x x ON OFF
11 OFF SF FF OFF ON OFF
12 OFF SF OFF FF ON OFF
13 OFF SF FF FF ON OFF
14 FF FF FF FF ON FF
The listed fourteen possible combinations will be here de-
scribed:
1 It identifies the initialization of the GSM engine. The
LED “Init” flashes quickly, with a period of 0.5 seconds
2 It identifies a problem for the internal memory of
DFGSMIII module. This may mean that the memory
has not been programmed or that it has been dam-
aged. The LED “Init” flashes slowly with a period of 1
second
3 It identifies the switching OFF procedure of DFGSMIII
module. It starts this procedure when a power supply
failure occurs; in this case the module does not switch
OFF immediately, but following a sequence that has
been set by DFGSMTools program. Therefore, for in-
stance, it sends the SMS related to power failure event
and after the defined time delay it completely switches
OFF
4 It identifies a communication error with the GSM en-
gine. In this case the system will force an automatic re-
boot of GSM engine after 60 seconds fixed delay
5 It identifies the critical errors returned by the SIM card,
requiring a reboot of GSM engine; this will be automat-
ically done after 60 seconds fixed delay
6 It identifies communication problems with the SIM card
currently placed in the module. For instance, the SIM is
not properly inserted or a SIM failure occurred. In this
case too the system will automatically reboot the GSM
engine after 60 seconds fixed delay
7 It identifies an error on the entering of the PIN code, for
instance the entered PIN code is wrong. In this case
the system enters a lock state waiting for the resolution
of the error on the PIN code. This requires a proper in-
tervention by DFGSMTools
8 It identifies an error on the entering of the PIN code.
The difference from the previous case, this error will be
reported after a normal start of the GSM engine. The
LEDs SMS IN and SMS OUT flash slowly with a period
of 1 second. In this case the system will automatically
reboot the GSM engine after 60 seconds fixed delay
9 It identifies that the remaining credit of the SIM card ex-
pired and therefore the SIM has to be recharged with a
new credit. The LEDs SMS IN and SMS OUT flashes
quickly with a period of 0.5 seconds; after 60 seconds
delay, the system will reboot the GSM engine. This
condition will be repeated at each attempt to send a
SMS in expired credit condition
10 It identifies the “normal operation” activity, in other
words the operating condition reached after the initial-
ization and with no events pending. The field LED
flashes with a period of 2 seconds and with an
ON time in respect to the OFF time (duty-cycle vari-
able as function of the strength of the GSM signal.
More the signal strength and more the LED will be ON
during the period
11 It identifies the reception of a SMS. The LED SMS IN
performs a sequence of fast flashes with a period of
0.5 seconds while the field LED continues to flash nor-
mally to shows the strength of the GSM signal
12 It identifies the sending of a SMS. The LED SMS OUT
performs a sequence of fast flashes with a period of
0.5 seconds while the field LED continues to flash nor-
mally to shows the strength of the GSM signal

Mapping
By BDTools (release 6.1.4 or higher it is possible to dis-
play the map related to DFGSMIII as shown in the follow-
ing figure:
Like for all modules of Domino family, the background of
the module symbol is in green colour if the module is con-
nected and properly operating, else the background will be
red.
As said before, DFGSMIII module tales 4 consecutive ad-
dresses, each one providing 16 digital points. When one of
the 16 points of each address becomes active, the related
“circle” will be red coloured. The following figure shows an
example:
Messages examples
Granted that the specific programming manual is the
unique reference for the configuration of DFGSMIII mod-
ule, simple examples will be described in the following only
to point out some performances of the module.
➢Messages from DFGSMIII to user: each SMS mes-
sage transmitted from DFGSMIII may report informa-
tion about one or more points, both digital and analog
ones (e.g. temperature ; the composition and the con-
tent of the messages are fully configurable by the user
through the tool program DFGSMTools. This program
allows to assign a well defined string to each Domino
input point (real or virtual or analog . In details, the fol-
lowing information must be defined:
✗the Domino input point to which the string is re-
ferred
✗a name (or phrase to be assigned to the point
status when it is at “0” logic level (e.g. “Alarm sys-
tem normal” or the name of the analog value
✗a name (or phrase to be assigned to the point
status when it is at “1” logic level (e.g.. “Alarm sys-
tem activated”
✗the event that causes the sending of the message,
for each SMS, and to which phone number it must
be sent
The following is an example of SMS message that user
can receive from DFGSMIII module:
Note as the message reports more information about
the Alarm System status and a temperature (this is only
an example . Another example of SMS from DFGSMIII
to user may be the following:

DFGSMIII
➢Messages from user to DFGSMIII for command ex-
ecution or information request: Each SMS message
sent by the user to DFGSMIII module may contain one
ore more commands; the commands can act on the
local outputs of the module or on one or more of the 64
fictitious inputs provided by DFGSMIII (remember that
the module is seen by the bus as an input module with
4 addresses, 16 points each one; these inputs must
be used in the Domino equations to perform the de-
sired actions .
The tool program DFGSMTools allows to define all re-
quired information as follows:
✗the string that, when received by DFGSMIII,
causes a command (e.g. Close-Shutters
✗the type of command to be executed; the possible
options are:
ON (switch ON a point or a local output
OFF (switch OFF a point or a local output
Pulse (causes a pulse on the related point or
on the local output; the duration of the pulse is
1 second
Send a SMS (cause the sending to the user of
a SMS that may be selected among the
defined ones
✗the point on which the selected action must be ex-
ecuted; each point has to be chosen among the 64
fictitious input points or the 4 local outputs
provided by DFGSMIII module
✗a comment to be assigned to the point
The following examples show command messages
from user to DFGSMIII module:
In the second example, in addition to real commands,
note the string AlarmStatus that will cause the sending
to the user of a SMS reporting the Alarm System
status. This is an example of message containing an
information request.
For more details about the programming, as said be-
fore, refer to the specific programming manual of
DFGSMIII module.
