GT863-PY Terminal Product Description

80269ST10026a Rev. 2 - 18/03/08

1 Overview

Aim of this document is the description of features, functions and interfaces of the Telit GT863-PY

Terminal which is a complete modem solution for wireless m2m applications based on the GE863-

PY core. Since this Terminal is ready for use as a subsystem for wireless connections, Safety
Information and basic instructions for taking the GT863-PY into operation are included, as well as
guidance to other documentation and practical hints for the first steps.

The Telit GT863-PY Terminal is GSM Mobile Stations (MS class B) capable of using the GSM
Circuit Switched Data (CSD), Fax and Short Message Services (SMS).

NOTE: Telit GT863-PY Terminal is an evolution of EZ10-PCS with PYG option and EZ10-QUAD-

PY fully compatible with the previous models.
The frequency bands and GPRS class are reported in the following table:

Product Name

GSM-850 / EGSM-900 / DCS-

1800 / PCS-1900 MHz Quad-

Class 10 GPIO

Telit GT863-PY

Band

The embedded PYTHON engine 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 (GPIO) on the RJ11 connector. Refer to the
chapter about Software Features in this Product Description.

GT863-PY Terminal Product Description

80269ST10026a Rev. 2 - 18/03/08

The following table summarizes the possible interface configurations (for details refer to the
dedicated chapters of this document):

GT863-PY
(GPIO & PYTHON)

RS232 Serial Interface for AT commands,

YES

data, fax, SMS

POWER 12V DC YES
AUX RJ11 6-pin configuration

GPIO:

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 GT863-PY 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 Quad-band evolution Telit GT863-PY includes features like sensing of hot removal of the SIM,
the higher upload speed of the GPRS Class 10 Packet Data transfer and the entire structure
results in a RoHS compliant product.

EASY GPRS® Embedded

Telit GT863-PY 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 GT863-PY 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 GT863-PY 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 GT863-PY includes a dedicated set of AT commands to run scripts in PYTHON

1

language
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 GT863-

PY is allowing self controlled operations.

With the Telit GT863-PY it is possible to configure the available GPIOs 4-7 as I

2

C or SPI bus.

GT863-PY Terminal Product Description

80269ST10026a Rev. 2 - 18/03/08

JAMMING DETECTION and REPORT
The Telit GT863-PY 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.

CMUX

CMUX ( Converter-Multiplexer) is a multiplexing protocol implemented in the Telit module that can
be used to send any data, SMS, fax, TCP data.

SAP (SIM Acess Profile)

The SAP feature allow the module to use the SIM of a remote SIM Server. This feature is
implemented using special AT Command on a Virtual circuit of the CMUX interface.

Multisocket

New functionality of the Telit modules, multisocket is an extension of Telit Easy GPRS feature,
which allows the user to have two contexts activated (that means two different IP address), more
than one socket connection (with a maximum of 6) and simultaneous FTP client service

The GT863-PY is compliant with the relevant parts of ETSI GSM Phase 2+ specifications (Normal
MS). Furthermore, Telit GT863-PY is 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 Terminal GT863-PY can be used in all EU countries and in other countries where a GSM­850/E-GSM-900/DCS-1800MHz or PCS 1900 MHz network is available.
It is necessary to insert a SIM (Subscriber Identity Module) on which the level of worldwide access
to the services of the related GSM/GPRS network depends.
