InduBox GPRS Reference manual – V1.0
1. Introduction
This manual is the reference book when setting up the InduBox 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 datacommunication is assumed.
The InduBox GPRS modem is a versatile communications device designed to provide a very flexible data communication solution for an industrial environment. The InduBox
GPRS modem contains a number of options to accommodate different communication speeds, power supplies and interfaces.
The InduBox GPRS is designed to transmit and receive data into the GSM data and 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 PPP packages. Thanks to the embedded TCP/IP and the implementation of a
“communication control” processor the InduBox GPRS is, for example, capable of opening/closing and maintaining a GPRS connection complete independently of the
DTE. Once the InduBox 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 InduBox GPRS is designed in a robust housing with different power supply options accepting a wide range of AC and DC (optional) voltages.
Besides serial communication using RS-232, other options are available like RS-422,
RS-485 or 20mA current loop. Check the possible available options.
Basically we have 4 InduBox GPRS models available :
InduBox GPRS
GSM/GPRS modem
InduBox GPRS( m )
GSM/GPRS modem with build-in Communication Control Processor
InduBox GPRS( ip )
GSM/GPRS modem with embedded TCP/IP
InduBox GPRS( m ip )
GSM/GPRS modem with embedded TCP/IP and build-in Communication Control Processor
Standard the InduBox is delivered with a 85 - 220 Vac power supply and a RS-232 interface. In option we have other possible power supplies and DTE interfaces.

Power Supply
The power supply (AC) must be connected to the InduBox GPRS modem via a 3 pin terminal block with screw contacts. Make sure the voltage supplied to the modem is in the range of the InduBox GPRS input voltage (see specifications for details on voltage range).
DTE Interface
The InduBox GPRS modem with RS-232 interface can be connected to a computer or similar device using the 4 pin terminal block. Inside the modem housing, direct onto the
PCB, a DB-9 connector is fitted. This RS-232 configuration port can be used during the initial setup.
Three different options are standard possible (other options are possible on request):
?
RS-232
?
2/4 wire 20 mA current loop + RS-232 config port

Watchdog circuit
A long-term watchdog circuit is implemented. Up to four different reset periods are possible (+/- 1, 6, 12 or 24 hour). The power supply of the 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 InduBox GPRS is ‘locked’ after e.g. an unexpected high ESD discharge or surge pulse 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.
A lot of things can be monitored via a 7 segment display.
The software for this “communication control” processor is will 100% be written to customer specifications.
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
InduBox GPRS modem!
Install a SIM card into the SIM card interface socket. Without a SIM card the InduBox
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 InduBox GPRS modem.

The InduBox 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 &W command automatically saves the baud rate, number of data bits, parity and number of stop bits.
You will find more information about the optional interfaces, the jumpers J3 to J8 and the possible connections in the “Installation & Configuration of the Interface option modules into the IndoBox modems”.

The InduBox GPRS modem can be delivered with a Communication Control Processor.
This ATMEL AVR RISC processor holds the necessary software to perform automatically communication processes like, opening a GPRS / Socket connection to a remote Socket server, sending a SMS message after an input change, change an output pin when a SMS message is received, …
Communication Control Processor designs are custom build. Please contact Bausch
Datacom NV for more information about the possibilities.
8. 7-segment display
The InduBox GPRS modem has a 7-segment display to monitor the Communication
Control Processor.
9. Push button
The InduBox GPRS modem has a simple push button below the 7-segment display.

12. Watchdog functionality
To prevent a “total lock-up” of the InduBox 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).
Up to four different reset periods are possible (+/- 1, 6, 12 or 24 hour). The power supply of the WAN module will be disconnected for a few seconds after the selected reset period 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 InduBox GPRS is “locked-up” with an active DCD signal the watchdog will never be able to reset the WAN module.
