| The DinBox GSM/GPRS is a serial V.24/RS-232 DIN-rail Quadband (850/900/1800/1900 MHz) GSM and EGSM/GPRS modem for M²M applications.The standard DinBox GPRS modem firmware in Open AT allows the modem to be connected serially by RS-232 with a non-IP enabled serial device and to communicate with the host system by IP number and port number, using GPRS, without disturbing the transparent communication between the meter and the host. This is very useful when upgrading non-IP enabled meter or serial units to IP without having to change the existing application.
