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.

4. SIM card
Disconnect the mains power before opening the
DinBox GPRS modem!
Install a SIM card into the SIM card interface socket. Without a SIM card the DinBox
GSM/GPRS will communicate with the DTE but will not respond properly on all
commands.
The International Mobile Subscriber Identity (IMSI) is used for internal signaling and is
saved on the SIM (processor card). If the SIM is removed from the terminal, any existing
connections are cleared and further call setup is prevented with the exception:
emergency calls.
See the +CIMI command for more details.
Use the +CGSN command to view the Product Serial Number of the DinBox GPRS
modem.
How to install the SIM card:
1. Disconnect the power and DTE interface.
2. Open the DinBox GSM/GPRS housing.
3. The SIM cardholder is placed between the 2 PCB connectors onto the PCB.
4. Carefully slide the metal bracket to the ‘Open’ position.
5. Insert the SIM card into the SIM card holder (mind the correct direction).
6. Close the SIM card holder and slide the metal bracket into the ‘Lock’ position.
7. Close the DinBox GPRS enclosure.
8. Connect power and DTE interface.
See the +CPIN command for more info about entering the PIN number.

The DinBox GSM/GPRS modem will detect the DTE port speed (auto baud), number of
data bits and parity type from the "AT" header that precedes every command (in async
mode).
The commands +IPR and +ICF saves the baud rate, number of data bits, parity and
number of stop bits.
5.3 I/O connections
“Communication Control” processor versions are equipped with I/O. We provide I/O on
three possible levels ; TTL input and output, opto coupler input and relais contact
output.
Below you will find the different characteristics of the different I/O’s.
•TTL
The 4 TTL I/O lines are directly connected 4 port pins of the ATMEL AVR micro
controller and can be used as digital I/O or ADC inputs.
All connections are guarded with a Transil for ESD protection. See chapter D for more information.

7. Watchdog functionality
To prevent a “total lock-up” of the DinBox GSM/GPRS a long term watchdog is
implemented. This function is created with a separate RISC micro controller. The micro
controller itself is guarded with it’s own internal watchdog (+/- 1 second refresh / WD
LED flash).
The power supply to the “Communication Control” processor and the modem module
will be disconnected for a few seconds after +/- 24 hour IF the modem is NOT
connected (inactive DCD signal).
If the reset period is ended and the modem is connected to a remote host (active DCD
signal) the reset will not be conducted.
If the reset period is ended and the watchdog already past a reset, because of an active
DCD signal, the reset will be conducted after +/- 10 minutes !
Otherwise, if the DinBox GSM/GPRS is “locked-up” with an active DCD signal the
watchdog will never be able to reset the WAN module.
8. Push button
The DinBox GSM/GPRS modem has a simple push button (switch) onto the PCB.
This switch can be used to start-up the DinBox GSM/GPRS without the “Communication
Control” processor. This function is necessary during first-time configuration of the
DinBox GSM/GPRS or for manual communication tests and debugging purposes.

and responses and are available via the serial DTE interface.
The DinBox GSM/GPRS is based on the Wavecom Wismo Q2403 module.
The original Wavecom manuals are available onto the CD-ROM.
Two manuals are available :
AT Commands Interface Guide.
This manual describes the AT-commands based messages exchanged between an
application and the DinBox GPRS modem in order to manage GSM related events or
services.
AT Commands Interface Guide for IP Connectivity.
(DinBox GPRS version only)
