GT863-PY Terminal Product Description

80269ST10026a Rev. 0 - 27/09/06

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:

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.

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

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

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

JAMMING DETECTION and REPORT

C or SPI bus.

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.

PYTHON is a registered trademark of the Python Software Foundation.

GT863-PY Terminal Product Description

80269ST10026a Rev. 0 - 27/09/06 The “Jammed” status is reported as unsolicited message through the AT-Command interface on the RS232 connection.

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, type 3 Volt Plug-in) on which the level of worldwide access to the services of the related GSM/GPRS network depends.

2.6.1 Supply voltage requirements

The DC power supply must be connected to the POWER input:

• Input voltage range 9 - 24V DC

• Nominal Voltage 12V DC

NOTE: these are the absolute maximum ratings – for use e.g. in trucks with 24V nominal voltage, an additional DC/DC converter has to be used.

• Power Supply current rating: min. 1,2A @12V

• Power Supply ripple: max. 120mV

• Input current in idle mode: 8mA @ 12V

• Input average current in communication mode: 110mA @ 12V

NOTE: In case that power supply equipment is to be ordered, its conformity needs to be verified with the mains supply voltage, frequency, connector type and other national requirements (e.g. certifications) in the countries of its use.

2.6.2 Power Connector

The power connector is on the left side of the terminal is Molex 4-pin connector (part no.:430450400 male)

2.7 General Purpose I/O

2.7.1 RJ11 (AUX) connector

The signals on the RJ11 connector has 4 digital general purpose inputs/outputs (GPIO). Connector type on the terminal is:

• Molex RJ11/6pin, part no.:95001-2661

The voltage range allowed on each pin is 0-3,6V DC. AUTO POWER ON is enabled.

VMOD = direct connection to the pin of the power supply voltage input of the Telit module (3.8V typical) and the output of the internal switching voltage regulator. The presence of this line at pin6 is to be considered as a low power output (<30mA) for pullup potential (requires external reduction of voltage to max. 3,6V DC!). NOTE: Connections to VMOD shall be made only when familiar with designing circuits conform to EMC requirements.

All General Purpose input / output lines on the RJ11 GPIO interface have a 100 pF bypass capacitor to ground and are connected to the related pins of the Telit module over a 100 Ohms series resistor.
