Inserting the SIM card
Before inserting or replacing the SIM card, always make sure that the
device has been disconnected from the mains and that no electrostatic
discharge is present in order to avoid damaging it.
Take all necessary measures to avoid electrostatic discharge.
 Shift the SIM card housing cover downward until it unblocks and
lift it.
 Carefully slide the SIM card into its housing cover.
 Lower the SIM card housing cover and shift it upward until it
blocks.
WARNING
The SIM card PIN must be DISABLED. If the PIN is
enabled, it must be disabled through a mobile phone.
Inserting the antenna
 Screw the antenna cable in to the connector on the top of the
module.
WARNING
NEVER connect the GSM500 M2M without having
previously installed the antenna. The device may get
damaged.
WARNING
Do not install the product near other electric or
electronic devices that were not especially designed to
be used with it. They could be subjected to RF
interference from the module.

Page 10
 Position the antenna with magnetic base so that any metal
surfaces do not block the signal.
Connections
 Connect the TEL terminal to a voltage free contact of an external
device.
 Connect the RL terminal (if present and if necessary) to an external
device.

Page 11
Connection to the power supply
Power supply via 230Vac external adapter
 Connect the external adapter to the specific input (D in the picture
at page 8.
 Connect the backup batteries (if present) to the dedicated input (H
in the picture at page 8).
 Close the device cover.
or
12Vdc power supply
 Connect the power supply cable to the terminal (F in the picture at
page 8) taking care to respect the polarity.
 Connect the backup batteries (if present) to the dedicated input (H
in the picture at page 8).
 Close the device cover, paying attention to the power supply cable.
WARNING
The backup batteries, if present, may be connected only
after GSM500 M2M has been supplied.
Note: the max voltage to be supplied to the mains terminal F
is 17 Vdc.
Note: the min voltage required to supply the GSM500 M2M
device by the mains terminal F is 10 Vdc.
Note: a protection cut-out switch must be installed upstream
to interrupt power supply in case of fault.

Page 12
Turning the GSM500 M2M device on
 Power the GSM500 M2M.
 Wait 30 seconds after power-up to give time to the GSM500 M2M
to register correctly with the GSM network.
 Make sure the red LED (device status) flashes briefly once every 3
seconds as shown in chapter “SIGNALS” (see page 22).
If the red LED flashes quicker and stays lit for a longer time (see page 22), the
GSM device has not properly registered with the GSM provider:
 Disconnect GSM500 M2M and make sure the SIM card is inserted
correctly and that the PIN is not locking it.
 See chapter “PROBLEM-DETECTION GUIDE” (page 24).

Page 13
Device mounting operations
 Check the GSM signal strength through the green indicator LED
(see chapter “SIGNALS”, page 22) and identify an area where the
signal is strong enough.
Note: the signal strength may vary according to the
telephone provider.
 Drill two holes with 5 mm diameter on the wall at a distance of 50
mm.
 Insert the 2 wall plugs and screws down until the screws are at a 5
mm distance from the wall.
 Place the GSM500 M2M device onto the two screws through the
two back slots.

GSM500 M2M installation recommendations
 The GSM500 M2M must be installed in a location where the radio
signal allows for using the GSM system.
 It is advisable to leave plenty of space around the device for
maintenance operations.
 Do not install the GSM500 M2M outdoors, since it lacks protection
devices against weather conditions that can damage the device (water,
humidity, etc.).
 Do not install the GSM500 M2M near electronic (radio or TV sets,
Personal Computers, wired radio systems, etc.) or magnetic (credit
cards, etc.) devices that could be subjected to RF interference from the
module: recommended distance from the antenna is min. 2,5 m.
 Do not install the GSM500 M2M near medical devices. Its operation
may cause damage to hearing aids or pacemakers.
 Always make sure that the device operation is permitted in the place of
installation (e.g. installation is not allowed in hospitals, airplanes, etc.).

PROGRAMMING
Programming via SMS is possible by any mobile phone or other device
supporting SMS. An SMS notifying that programming has been
completed will be sent back by the GSM500 M2M to the same telephone
number that forwarded the programming SMS.
WARNING
Programming outgoing SMS from the Internet may
not be successful if the requested format is not
respected.
When the GSM500 M2M sends or receives an SMS, the line status LED
(blue) will turn on.
Message format
Each programming SMS contains one or more programming commands.
The message format is required to be as follows:
Et-vm1 cmd par cmd par … cmd par
Where:
Et-vm1 : programming string start
cmd : programming command
par : parameter correlated to the command
Each command and each parameter must be separated by a space.
Example:
it is required to set the telephone number 0039333123123123.
Outgoing message text:
Et-vm1 alertphone 0039333123123123

Page 16
Notification message format
The format of the notification message is the same as the programming
message format.
SMS notifying an accepted command:
ET?VM1 cmd par
