  • Interfaces & Connectors:
    Non isolated standard serial RS-232 configuration interface (RJ-45) with 8 contacts (configuration via AT-commands), connected to SL6087 UART1
    DTE Interfaces:
    3-wire serial RS-232 (RXD, TxD, GND') & '+V' connection / Galvanically separated / Connected to UART1 of the GPRS module
    3-wire serial RS-485 (A, B, GND') & '+V' connection / Galvanically separated / Connected to UART2 of the GPRS module
    Simultaneous access over one single GPRS link possible for 2 non IP enabled applications (e.g ‘old’ electricity meters) thanks to the embedded Open AT program and thanks to the 2 logically seperated and isolated RS-232 and RS-485 serial interfaces (UART1 to RS-232 & UART2 to RS-485). As a result the modem is able to perform in several transparent IP / AMR metering scenario's, even if the meter does not have an IP stack (Socket Server Mode, Socket Client Mode, Socket Dual mode, GPRS mode - FOTA over FTP -). Even secure communication with the Praxis back-office can be set up by adding RSA encryption code to the embedded software of the modem.

  • Reset: Long term, configurable watchdog: to prevent a lock-up the Indubox GSM/GPRS IX will have an automatic and 'hard' reset each 1 to 68 hours (configurable) and/or will perform an externally triggered (meter) 'hard' reset by the '+V'-connection (pin 1 of the RS-232 and RS-485 interfaces: 5~25 Vdc in or +5V' out) : disconnection of power supply during 20 seconds when a negative slope (5-25V to 0V) is detected on the '+V'-input.
  • Certification: CE approved, TST 25-3 approved according to extended immunity requirements in the Belgium electricity market

Additional Info

Praxis MMS (Modem Management System):
For mass deployment and management of the InduBox modems Bausch Datacom developed the 'Praxis' Modem Management System. Praxis consists of 3 system blocks: the modem firmware, the Server Software and the Client Software.
The modem firmware of the new InduBox GSM VIII and IX modems is an OpenAT application supporting the grouping and mass deployment services offered by the MMS Client and Server software. For example every 15 minutes the InduBox modem will measure the reception level <rssi> of  the signal sent by the closest GSM Base Transceiver Station (BTS) as well as the received bit error rate <ber>. In fact, the InduBox modem will keep statistics of 'rssi' and 'ber', time of watchdog restart, number and time of switching between CSD and GPRS, settings of the RS-232, RS-485 and config ports (baudrate, parity, stopbits), GPRS settings (APN...), IMEI code etc...These statistics are stored internally in the modem and will be retrieved on a daily base by 'Praxis', the MMS Server software.
Praxis, the Bausch MMS Server Software will monitor directories for files to import (e.g. from the AMR/MDM system), it will monitor the Database for jobs to be done (entered by the Bausch Client Software), perform scheduled tasks (time-based) and it will get statistics kept by the InduBox modems. The server includes a DataBase to keep all necessary and unique information of each InduBox modem.
The Bausch Client Software, running on a Windows PC, provides a GUI wich allows grouping/selecting of modems by telecom operator, operational mode (GSM, GPRS), software version, filtering (based on data in the modem database)...Secondly it provides for scheduled and grouped updating of modem firmware - FOTA over FTP -, switching between different AMR metering scenario's (Socket Server Mode, Socket Client Mode, Socket Dual mode, CSD mode, GPRS mode) and setting of a different baudrate (between modem and meter) or entering another modem configuration (APN name,...). And finally on a daily base it will get the modem statistics out of the Database and export a daily file with signal strength of the modems in the field for use in the AMR/MDM system.

InduBox GSM IX provides for simultaneous access over one single GPRS link for 2 or more non IP enabled ‘old’ electricity meters:
The InduBox GSM/GPRS IX is built in a sealable housing with transparent lid and has two different and galvanically seperated serial interfaces, one RS-232 (3-wire), one RS-485 (3-wire): female RJ-45 connectors make installation to the electricity meter very easy.
At the heart of the modem, the Sierra Wireless GPRS SL6087 module supports a powerful software development environment - OpenAT -, which allows embedded ANSI C applications to be executed directly on the Wireless CPU. This means Bausch Datacom can integrate tailor made applications or communication protocols on the customer's demand, a very powerful tool!
The basic ‘socket server' application in OpenAT allows the modem to be connected by RS-232 and/or RS-485 with a non-IP enabled (electricity) meter and to communicate by IP number and port number using GPRS. In this way a transparent communication with the host system can be maintained! The modem is default in a GPRS mode but can be switched to GSM data and vice versa by Praxis. The modem firmware also offers different AMR scenarios (Socket Server or Client mode, Socket Dual Mode etc...) and even secure communication with the Praxis back-office can be set up by adding RSA encryption code to the embedded software of the modem.
The modem is especially conceived for 'heavy' industrial environments. The modem is tested and approved according to the TST 25-3 extended immunity requirements in the Belgian electricity market. When testing EN61000-4-3 - electromagnetical compatibility - Laborelec, the official Belgian lab creates a test environment which generates 30 V/m field strengths instead of the standard 'normal' field strength of 10 V/m (CISPR24 level = 10 V/m).
