GPRS M-Bus Master (M-bus water meters, heat meters and other meters)

1. Brief introduction
The GPRS M-Bus Master M Series is a wireless GPRS Automatic Meter Reading(AMR) System. It embedded with high-performance ARM®Cortex®-M3 32-bit RISC MCU with real-timeμC/OS-II RTOS and industrial GPRS Engine inside. It is special for communication between monitoring center and M-Bus meters, 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 M Series is special for automatic meter reading(AMR) system, compatible with EN 1434-2008 protocol and M_Bus interface, it supports 60/120/240/360 M-BUS meter 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.
The user can remotely setup the GPRS M_Bus Master parameters via GPRS. The GPRS M_Bus Master will periodically automatic reading the meters, and upload the meters' value to monitoring center transparently. The data format that uploading by GPRS is the same as the meters data format. It is convenient for users to maintain its present monitoring center.
   
2.Where Does the GPRS M_Bus Master M Series Suitable for?

LED& Interface Instruction

LED	Power	Power indicator, once powered on, it will always on.
	TX	Transmit data indicator, only transmitting data will flick;
	RX	Receive data indicator, only receiving data will flick;
	GSM	GSM signal indicator, flicks after power on, online will flick slowly.
	OVL	Overload Alarm indicator, turn on 2s after power on, then goes off. If the overload alarm indicator always on, stands for the GPRS M_Bus Master connected too many meters, please remove some of them.
