7 1. Introduction This manual is the reference book when setting up the InduBox GSM IV 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 GSM IV modem is a versatile communication device designed to provide a very flexible data communication solution for an industrial environment. The InduBox GSM IV modem contains a number of options to accommodate different communication speeds, power supplies and interfaces. The InduBox GSM IV is designed to transmit and receive transparent- ASCII formatted data on a GSM data channel. Communication between the InduBox GSM IV and a DTE range from 300 to bps. With the GPRS 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 separated interfaces are available like RS wire and RS wire. The InduBox GSM IV is designed in a robust housing with different power supply options accepting a wide range of AC voltages / 02 / 19 7

8 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 IV 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 IV input voltage (see specifications for details on voltage range). Long Term Watchdog A long term watchdog circuit is implemented. The modem will be reseted each 24 hour 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 haertbeat -LED is implemented to check the long term watchdog / 02 / 19 8

9 Switched regulator To create the necessary dc-voltage (Vgsm) to power the GSM/GPRS module a 2A step down switching regulator is implemented. Configuration Interface The InduBox GSM IV 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 Wavecom GSM/GPRS module. This interface has a RJ-45 connector. Isolated DTE interfaces The InduBox GSM IV has 2 galvanically isolated serial interfaces : 3- wire RS-232 (RxD, TxD, GND ) 3- wire RS-485 (A, B, GND ) Each interface has it s own connector and can be used in parallel. V.24 Status LED s The V.24 lines to and from the GSM/GPRS module have a LED indicator. GSM/GPRS module The InduBox GSM IV has a built-in Wavecom Quik GSM/GPRS module. Following configurations are possible with or without OpenAT firmware : GSM only GSM/GPRS GSM/GPRS with TCP/IP stack (socket only) GSM/GPRS with TCP/IP stack (socket only) with aditional processor 4 dip switches and 2 LED s are directly connected to the GPIO of the Wavecom module. An OpenAT program can be implemented to use these switches and/or LED s / 02 / 19 9

11 4. SIM Card Disconnect the mains power before opening the InduBox GSM IV modem! Power Supply Wavecom MAINS RS-232 RS-485 Install a SIM card into the SIM card interface socket. Without a SIM card the InduBox GSM IV 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 one exception: emergency calls. Use the +WIMEI? command to view the IMEI code of the GSM module / 02 / 19 11

12 How to install the SIM card: 1. Disconnect the mains power and DTE interface. 2. Open the InduBox GSM IV enclosure. 3. The SIM cardholder is placed in the upper right corner onto the PCB. 4. Slide the upper part to the LEFT position. 5. Insert the SIM card into the upper part of the card holder. 6. Close the upper part of the SIM cardholder and carefully slide the upper part to the right (LOCK) position. 7. Close the InduBox GSM IV enclosure. 8. Connect mains power and DTE interface. See the +CPIN command for more info about entering the PIN number / 02 / 19 12

13 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 IV modem. The InduBox GSM IV has three types of connectors; one internal RJ-45, three srcew connectors with corresponding plugs and one FME connector. Mains L1 N RS-232 RxD TxD GND RS-485 B A GND Disconnect the mains power before connecting or disconnecting the power and/or DTE plugs! 5.1 Mains Power Connection PIN 1 L1 2 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 IV input voltage (see specifications for details on voltage range). When the InduBox GSM IV modem is connected via a standard mains plug, the used mains socket must be directly accessible and easy reachable / 02 / 19 13

14 5.2 Non isolated DTE Interface Only devices which are conform with the safety regulations can be connected to the DTE port! This interface must be used to configure and upload firmware to the GSM/GPRS module. This interface is accessible via a RJ-45 8-pin connector, is not isolated and has all standard V.24 interface lines. A RJ-45 to a standard female DB-9 connector cable is available.

To avoid a double echo during command mode, the modem echo should be disabled ; ate0 disable modem echo 2008 / 02 / 19 22

23 9. Watchdog Functionality To prevent a total lock-up of the InduBox GSM IV a long term watchdog is implemented. This function is created with a separate microcontroller. The microcontroller itself is guarded with it s own internal watchdog (+/- 1 second refresh / LED flash). By default a reset period of 24 hour is preprogrammed. 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! Otherwise, if the InduBox GSM IV is locked-up with an active DCD signal the watchdog will never be able to reset the WAN module. 10. AT Command Interface More information about the commands to the InduBox GSM IV modem, and the responses from the InduBox GSM IV modem, are described in the Wavecom reference manual AT commands interface guide. This manual can be found onto the CD-ROM delivered with the InduBox GSM IV modem / 02 / 19 23
