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.
