1. Introduction

This manual is the reference when setting up the InduBox GSM VIII 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 InduBox GSM VIII modem is a versatile communication device designed to provide a very flexible data communication solution for an industrial environment. The InduBox GSM VIII modem contains a number of options to accommodate different communication speeds, power supplies and interfaces.

The InduBox GSM VIII is designed to transmit and receive –transparent- ASCII formatted data on a GSM data channel. Communication between the InduBox GSM VIII and a DTE range from 300 to 115.200 bps. With the GPRS/UMTS option and embedded TCP/IP stack, data can be send/received into a TCP/UDP socket to and from a remote socket server.

Besides serial communication using standard RS-232, other galvanically and logically separated interfaces are available like RS-232 3-wire and RS-485 3-wire.

Besides a periodical (hard) reset, configurable between 1 and 168 hour, an external modem reset is possible via the additional 'V+'-connection to ensure a proper modem working.

The InduBox GSM VIII is designed in a robust housing with different power supply options accepting a wide range of AC voltages.



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.

AC/DC power supply The mains supply (ac) must be connected to the InduBox GSM VIII modem via a 2 pin terminal block with screw contacts. Make sure the voltage supplied to the modem is in the range of the InduBox GSM VIII input voltage (see specifications for details on voltage range).

Long Term Watchdog A long term watchdog circuit is implemented. The modem will perform a reset each 1 to 168 hour (configurable) and/or if necessary via the external '+V'-connection to prevent a lock-up. The power supply of the GSM/GPRS module will be disconnected for a few seconds after the reset period. A ‘heartbeat’-LED is implemented to check the long term watchdog.



Switched regulator To create the necessary dc-voltage (Vgsm) to power the GSM/GPRS module a 2A step down switching regulator is implemented.

Configuration InterfaceThe InduBox GSM VIII modem has one complete (TxD, RxD, DCD, DTR, RTS, CTS, RI and GND) RS-232 interface. This RS-232 interface is not isolated and must be used to configure and/or update the Sierra Wireless (Wavecom) GSM/GPRS module. This interface has a RJ-45 connector.

Isolated DTE interfaces The InduBox GSM VIII has 2 galvanically isolated serial interfaces :

3- wire RS-232 (RxD, TxD, GND’) :

This interface is connected (galvanically separated) to the internal configuration interface (RJ-45) the UART1 of the Q2686 GSM/GPRS module. Pin 4 can be used for external reset (V') or for powering (100 mA Imax) an external device (+5V'), selectable via resistor stuffing.

3- wire RS-485 (A, B, GND’) :

This interface is connected (galvanically separated) to the UART2 of the Q2686 GSM/GPRS module.

Pin 4 can be used for external reset (V') or for powering (100 mA Imax) an external device (+5V'), jumper selectable via JP2.

V.24 Status LED’s The V.24 lines to and from the UART1 GSM/GPRS module have a LED indicator.

GSM/GPRS module The InduBox GSM VIII has a built-in Sierra Wireless (Wavecom) Q2686 GSM/GPRS Quad band module. Different applications/configurations are possible with or without OpenAT firmware.

4. SIM Card

Disconnect the mains power before opening the InduBox GSM VIII modem!

Install a SIM card into the SIM card interface socket. Without a SIM card the InduBox GSM VIII will communicate with the DTE but will not respond properly on all commands.

Must applications are using a SIM card with disabled PIN code request !

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 one exception: emergency calls.

Use the +WIMEI? command to view the IMEI code of the GSM module.

5. Ports and Connectors

Before you start the installation, take a moment to become more familiar with the possible connections to and from the InduBox GSM VIII modem.

The InduBox GSM VIII has three types of connectors; one internal RJ-45, three screw connectors with corresponding plugs and one FME connector.

Disconnect the mains power before connecting or disconnecting the power and/or DTE plugs !

5.1 Mains Power Connection

PIN1 L12 N

Always disconnect the mains power before connecting or disconnecting the power plug. Make sure the voltage supplied to the modem is in the range of the InduBox GSM VIII input voltage (see specifications for details on voltage range).

When the InduBox GSM VIII modem is connected via a standard mains plug, the used mains socket must be directly accessible and easy reachable.

9. Watchdog Functionality

To prevent a “total lock-up” of the InduBox GSM VIII a long term watchdog is implemented. This function is created with a separate micro-controller. The micro-controller itself is guarded with it’s own internal watchdog (+/- 1 second refresh / LED flash).

This long term watchdog has 2 possible ways to reset the modem :1. configurable periodically reset2. external reset triggered by the '+V'-connection

9.1 Periodically reset

The power supply will be disconnected, after a controlled and proper GSM disconnection, during 20 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 + 10 minutes and the watchdog already past a reset, because of an active DCD signal, the reset will be conducted! Otherwise, the InduBox GSM VIII can be “locked-up” with an active DCD signal the watchdog will never be able to reset the WAN module.

Time is programmable via the serial setup menu of the modem.This menu is accessible via the RJ-45 serial interface (9600 bps 8N1) after hitting the blue push 'switch' located next to the reset processor onto the modem printed circuit board.

| -- START --|| Bausch Datacom InduBox GSM VIII setup [V1.0]|| Reset period time select [currently 24 hour]| Do you want to change this [y/n] :

Enter 'y' if you want to change the default 24 hour to another value.The new value will automatically be stored in non volatile RAM.

9.2 External reset

The power supply will be disconnected, after a controlled and proper GSM disconnection, during 20 seconds when a negative slope (5-25V to 0V) is detected on the '+V'-input.

There is no DCD check done in this reset mode.
