The GPRS M Bus Master S281 is a GPRS DTU and GPRS Automatic Meter Reading(AMR) System. It embedded with High reliable ARM9 MCU and industrial GPRS Engine inside. It is special for communication between monitoring center and M-Bus, RS232,RS485 intelligent instrument and industrial meters over wireless GPRS Network. It is the best solution for meter reading master station or controller.

The GPRS M Bus Master S281 is special for automatic meter reading(AMR) system, it supports 128 M BUS Slaves, like M BUS heat meters, M-BUS Gas meters, M BUS electricity meters, M BUS Water meters and other M BUS meters, and then transfer the meters data over wireless GPRS Network to Server.

Moreover, the GPRS M Bus Master S281 supports transparent and non transparent data transfer by RS485 and RS232 over GPRS. It can be connected to intelligent instrument and industrial meters directly to read the values of analog input, TTL, digital input, pulse counter and so on.

The GPRS wireless communication has become widely used of industrials and utilities and many customers are requiring reliable, flexible and cost-effective data channel to build their information system. Many applications such as Remote device monitoring, remote read meters, ATM, data logging system, POS, SCADA and surveillance system will require data channels covered all country.
