1 Overview
Aim of this document is the description of features, functions and interfaces of the Telit EZ10
TERMINAL FAMILY of wireless GSM/GPRS cellular modems. Since these Terminals are ready
for use as a subsystem for wireless connections, Safety Information and basic instructions for
taking the EZ10 into operation are included, as well as guidance to other documentation and
practical hints for the first steps.
All of the Telit EZ10 Terminals are GSM Mobile Stations (MS class B) and capable of using the
GSM Circuit Switched Data (CSD), Fax and Short Message Services (SMS).
The frequency bands, GPRS class, availability for GSM Voice Services and the configuration of the
RJ11 connector in relation to the names of the products are reported in the following table:
Frequency Bands GPRS GSM
Voice RJ11 AUX Connector Product Name
EGSM900/1800 MHz
Dual-Band Class 8 Yes AUDIO Telit EZ10-GPRS
EGSM900/1800/ PCS1900 MHz
Tri-Band Class 10 NO GPIO Telit EZ10-PCS
(with PYG Option)
For the use of GSM Voice Services, an external microphone, earphone or amplified loudspeaker
needs to be connected to the RJ11 AUX=AUDIO connector of the Audio version of the EZ10
Terminal.
The PYG Option allows to perform stand-alone operations with the EASY SCRIPT feature,
interpreting user-defined scripts in PYTHON language, e.g. to read external sensors connected to
the General Purpose Inputs / Outputs on the RJ11 connector. Refer to the chapter about Software
Features in this Product Description.

On the AUDIO version of the EZ10 Terminal Models, the 6-pin RJ11 AUX connector is configured
with a microphone input and earphone output, whereas the PYG version have digital General
Purpose Inputs/Outputs (GPIO) instead. The following table summarizes the possible interface
configurations (for details refer to the dedicated chapters of this document):

(AUDIO) EZ10-PCS - PYG Option (GPIO & PYTHON)
RS232 Serial Interface for AT
commands, data, fax, SMS YES YES
POWER 12V DC with digital

“power good” supervision
YES YES
AUX RJ11 6-pin configuration AUDIO (GSM Voice Service):
GND
Remote ON/OFF
Microphone in (balanced)
Earphone out (unbalanced)
Vmod (3,8 V DC)
Remarks:
• Backward compatible to
EZ10-GSM and previous
versions of EZ10-GPRS, -
PCS and -PYTHON.
GPIO: (no Audio)
GND
GPIO 4,
GPIO 6 / Alarm
GPIO 7 / Buzzer
GPIO 5
Vmod (3,8 V DC)
Remarks:
• Automatic POWER ON.
• GPIOs can be configured as
I2C or SPI bus by PYTHON
script elements.
The EZ10 allows to be remotely controlled by AT commands (GSM 07.07 and 07.05) and the
connection to the host controller (Data Terminal Equipment DTE) is established through one
RS232 standard port. This port serves also for serial bi-directional Data and Fax transfer.
All the interfacing is done by 4 connectors placed on the front and rear panels.
The tri-band evolution Telit EZ10-PCS with PYG Option includes new features like sensing of hot
removal of the SIM and the higher upload speed of the GPRS Class 10 Packet Data transfer.
EASY GPRS® Embedded
Telit EZ10-GPRS /-PCS with PYG Option embeds TCP/IP stack and DNS query protocol. Static
and dynamic IP allocation, PPP and UDP as well as FTP Client are supported. Developers just
need to add Telit Proprietary AT commands to establish a TCP/IP connection through the GPRS
network.
EASY FREQUENCY SCAN® Function
Telit EZ10-PCS with PYG Option includes a dedicated set of AT commands to scan all the GSM
channels, reporting all available parameters. With EASY FREQUENCY SCAN® the GSM network
coverage at the location of the EZ10-PCS PYG Terminal can be examined even without inserted

SIM in order to select the provider with the best field strength, the most channels or base
transceiver stations and to optimize the antenna position.
EASY SCRIPT® Function
Telit EZ10-PCS with PYG Option includes a dedicated set of AT commands to run scripts in
PYTHON1language within the module. By using this EASY SCRIPT® feature, the script inside the
module interacts with the interfaces, allowing other tasks to interrupt it. The script interpreter
engine of Telit EZ10-PCS wireless modem with PYG Option is allowing self controlled
operations.
With the Telit EZ10-PCS with PYG Option it is possible to configure the available GPIOs 4-7 as
I2C or SPI bus.
JAMMING DETECTION and REPORT
The Telit EZ10-GPRS /-PCS with PYG Option offers the Jamming Detection and Report
functionality, which allows the unit to detect attempts to discontinue GSM communication by
interfering with the GSM radio signal. The “Jammed” status is reported as unsolicited message
through the AT-Command interface on the RS232 connection.
The EZ10 is compliant with the relevant parts of ETSI GSM Phase 2+ specifications (Normal MS).
Furthermore, Telit EZ10-GPRS /-PCS are certified after the full conformity assessment against
1995/5 EC and R&TTE Directive and they don’t require any further certification test effort and
expense. The Terminals of the EZ10 family can be used in all EU countries and in other countries
where a GSM 900/1800 MHz or PCS 1900 MHz network is available.
It is necessary to insert a SIM (Subscriber Identity Module, type 3 Volt Plug-in) on which the level
of worldwide access to the services of the related GSM/GPRS network depends.
NOTE: The availability of the services of the GSM/GPRS networks, their quality and parameters
depend mainly on the contractual conditions of the subscription to receive the SIM (Subscriber
Identity Module) from the Mobile Network Operator or Service Provider.
The behavior of the networks may be different in certain details, thus it is always recommended
that
• A complete and correct set-up of all parameters is included in the Application;
• The Application contains verification routines for the connections and transmissions,
• For critical communications, fall-back solutions to other services of the networks are
implemented (e.g. SMS or Call, GPRS or CSD);
• The Application allows to update the Software of the contained GSM/GPRS engine;
• A validation of the Application in the relevant networks has been carried out.
Before importing the products in other than EU countries, make sure that eventually required
national Certifications of Conformity and licenses are available. It is possible that conformity
regulations contain conditions for the use of the product in the related countries. Please, refer to
the CONFORMITY ASSESSMENT ISSUES chapter of this Product Description for more
information, or contact the supplier.
