1. Introduction

This manual is the reference book when setting up the DinBox GSM/GPRS modem for

your application. Because of the nature of this product and it's field of application, some

degree of technical background knowledge regarding the application and data-

communication is assumed.

The DinBox GSM/GPRS modem is a versatile communications device designed to

provide a very flexible data communication solution for an industrial environment. The

DinBox GSM/GPRS modem contains a number of options to accommodate different

communication speeds, power supplies and interfaces.

The DinBox GSM/GPRS is designed to transmit and receive data into a GSM data

and/or a GPRS channel.

But … there is more …

Information (serial data and/or input/output lines) can be transmitted/received via a

TCP/IP socket, e-mail, FTP, SMS or normal GSM data to and from remote host

systems.

GPRS connection can normally only be used if the DTE has TCP/IP capability to create

and send TCP/IP - PPP packages. Thanks to the embedded TCP/IP and the

implementation of a “Communication Control” processor the DinBox GSM/GPRS is, for

example, capable of opening/closing and maintaining a GPRS connection complete

independently of the DTE. Once the DinBox GSM/GPRS has opened the GPRS

connection the DTE can transmit and receive transparent ASCII data with a host

system.

Thanks to the 4 I/O lines it’s possible to read or change the status of control lines.

The DinBox GSM/GPRS is designed in a robust DIN rail housing with different power

supply options accepting a wide range of DC voltages.

Basically we have 5 DinBox GSM and 5 DinBox GPRS models available :

2. Block Diagram

The block diagram below details the location and interconnection of the different

functional units within the modem. The most important units are briefly described.

Power Supply

The power supply (DC) must be connected to the DinBox GSM/GPRS modem via a

terminal block with screw contacts. Make sure the voltage supplied to the modem is in

the range of the DinBox GSM/GPRS input voltage (see specifications for details on

voltage range). This input is protected against reversed polarity with a serial diode.

DTE Interface

The DinBox GSM/GPRS modem has a RS-232 interface (RJ-45) which can be

connected to a computer or similar DTE device via included RJ-45/DB-9 serial cable.

GSM/GPRS Modem

The DinBox GSM/GPRS modem has a Wavecom GSM/GPRS module on board.

Connection with the GSM dual band antenna is done via a standard SMA connector.

Watchdog circuit

A long-term watchdog circuit is implemented. The power supply of the Wavecom

GSM/GPRS module and the “Communication Control” processor will be disconnected

for a few seconds after the selected reset period.

If a part of the DinBox GSM/GPRS is ‘locked’ after e.g. an unexpected high ESD

discharge, surge pulse or an internal lock-up, this watchdog will always insure the

continuity of communication.

“Communication Control” Processor

This processor can monitor the whole communication process. This processor will also

control the 4 I/O lines and will perform the necessary action when input changes are

detected or when data is received to change output pins.

We have different basic “Communication Control” applications available :

DinBox GSM

-2 input – if input is changed -- SMS send

-2 output – SMS received – output will be changed

-1 input – SMS / 1 output SMS

DinBox GPRS

-1 input – to open a socket / 1 output – active when the socket is opened

-2 input – if input is changed – send predefined message in socket to a host

-2 output – receive predefined message in socket from a host – output will be

changed

The software for this “Communication Control” processor can be adapted for special

customer needs.

Please contact Bausch Datacom NV to have more information about all the possibilities

and existing implementations.
