Contatto
ModGSM
III
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
ModGSMIII module takes, inside the Contatto bus, one 4-
channel 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 inco-
ming messages (SMS) of ModGSMIII module. These
points will be therefore used to perform the desired actions
through a proper programming of the Contatto system. The
support program ModGSMTools allows to define the ad-
dress of ModGSMIII module. No output address are used
by this module.
Note:
it is not possible to assign the bus address of
ModGSM
III
module by FXPRO programmer.
A white label on the front panel of ModGSM
III
allows to
write the address assigned to the module for an immediate
visual identification.
ModGSM
III
must be set by the program ModGSMTools so
that to define the several parameters needed for its proper
operation;
for more details refer to the programming
manual.
Wiring diagram
A 5-pole removable terminal block on the top side of
ModGSM
III
module allows the connection to the
Contatto
bus and to the related power supply.
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
for 24V dc current (the voltage on outputs O3 and O4 is
about equal to the voltage applied to terminals 13 and 14).
A 9-way terminal block on the bottom right side of the mod-
ule allows the connection to the 8 local inputs that
must be
potential free
