DESCRIPTION
GSM500
GSM500 is a gateway that, connected to a fixed telephone or to the PSTN
input terminals of a PABX or autodialer, allows you to make and receive
calls over the GSM network. For correct operation, a GSM SIM card is
required.
GSM500 GC
The GSM500 GC gateway comes with built-in backup batteries.
GSM500 R2R
The GSM500 R2R gateway comes with built-in backup batteries and a
relay output which can be activated either locally or remotely via SMS.
GSM500.net
The GSM500.net gateway comes with built-in backup batteries and
female DB-9 connector for data transmission (through standard RS-
232/RS-485/CAN-bus) and SMS forwarding (through standard RS-
232/CAN-bus). For correct operation, a GSM (voice + data) SIM card is
required (GPRS data connection).
3G.next Voice
3G.next Voice is a gateway that, connected to a fixed telephone or to the
PSTN input terminals of a PABX or autodialer, allows you to make and
receive calls over the UMTS/GSM network. The 3G.next Voice gateway
comes with built-in backup batteries and a relay output which can be
activated either locally or remotely via SMS.
3G.next
The 3G.next gateway comes with a female DB-9 connector for data
transmission and SMS forwarding and a micro USB A/B port for direct
connection to the UMTS/GSM module (optional). For correct operation
the SIM card must be enabled for voice and data traffic.

INSTALLATION
Installation recommendations
 The gateway must be installed in a location where the radio signal
allows for using the GSM/UMTS system.
 It is advisable to leave plenty of space around the gateway for
maintenance operations.
 Do not install the gateway outdoors, since it lacks protection devices
against weather conditions that can damage the gateway (water,
humidity, etc.).
 Do not install the gateway near electronic (radio or TV sets, Personal
Computers, wired radio systems, etc.) or magnetic (credit cards, floppy
disks, 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 gateway 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.).
EU declaration of conformity
Hereby, Esse-ti S.r.l. declares that the equipment type GSM500/3G.next
is in compliance with Directive 2014/53/EU.
The full text of the EU declaration of conformity is available from the
following Internet address:
https://www.esse-ti.it/en/dichiarazioni-di-conformita

Page 11
Inserting the SIM card
Before inserting or replacing the SIM card, always make sure that the
gateway 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 gateway without having previously
installed the antenna. The gateway 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.
 Position the antenna with magnetic base so that any metal
surfaces do not block the signal.

Page 12
Connection to the telephone line
 Connect the gateway to a standard telephone or to the PSTN input
terminals of a PABX or autodialer via the RJ-11 connector (F in the
picture at page 8 / H in the picture at page 9);
or
 Connect the gateway to a standard telephone or to the PSTN input
terminals of a PABX or autodialer using the TEL terminal (H in the
picture at page 8/ L in the picture at page 9).
Connection to the power supply
Power supply via 230 Vac external adapter
 Connect the external adapter to the specific input (G in the picture
at page 8 / I in the picture at page 9).
 Connect the backup batteries (if present) to the dedicated input (M
in the picture at page 8 / O in the picture at page 9).
 Close the gateway cover.
or

Page 13
12 Vdc power supply
 Connect the power supply cable to the specific terminal (I in the
picture at page 8 / M in the picture at page 9) taking care to
respect the polarity.
 Connect the backup batteries (if present) to the dedicated input (M
in the picture at page 8 / O in the picture at page 9).
 Close the gateway cover, paying attention to the power supply
cable.
WARNING
Backup batteries, if present, may be connected only
after gateway has been supplied
Note: the max voltage to be supplied to the 12 Vdc terminal
is 17 Vdc.
Note: the min voltage required to supply the gateway by the
12 Vdc terminal is 10 Vdc.
Note: a protection cut-out switch must be installed upstream
to interrupt power supply in case of fault.
Turning the gateway on
 Power the gateway.
 Wait 30 seconds after power-up to give time to the gateway to
register correctly with the GSM/UMTS network.
 Make sure the red LED (device status) flashes briefly once every 3
seconds as shown in chapter “SIGNALS” (see page 43).
If the red LED flashes quicker and stays lit for a longer time (see page 43), the
gateway has not properly registered with the GSM/UMTS provider:
 Disconnect the gateway and make sure the SIM card is inserted
correctly and that the PIN is not locking it.
 See chapter “PROBLEM-DETECTION GUIDE” (page 45).

Page 14
Gateway mounting operations
 Check the GSM/UMTS signal strength through the green indicator
LED (see chapter “SIGNALS”, page 42) 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 gateway onto the two screws through the two back slots.

PROGRAMMING
Programming can be carried out locally via a multi-frequency telephone
or remotely via SMS.
PROGRAMMING BY TELEPHONE
 Connect a standard telephone to the gateway via the RJ-11
connector (F in the picture at page 8 / H in the picture at page 9)
or using the TEL terminals (H in the picture at page 8 / L in the
picture at page 9).
 Lift the handset and dial the desired programming code (see table
“Programming by telephone”).
Note: at the end of each programming carried out correctly,
you will hear a confirmation tone, while an error tone
will be heard in case of error. In any case, the
dialling tone will follow, after which you can proceed
with the programming or make a call.
Note: during programming, the inter-digit dialling time must
not exceed 5 seconds (see the programming “Inter-
digit dialling time”). Once 5 seconds has elapsed
without digits you will hear the dissuasion tone and
you will have to wait the dialling tone or to hang up.
Note: programming can be carried out even if the signal is
absent. After the confirmation or the error tones, the
dissuasion tone will follow, after which you can
proceed with programming or hang up.
Note: in the table “Programming by telephone” factory
default values are highlighted in bold.
