1.1 Brief Introduction
MD-309 is a 2G DTU produced by eTung in 2010. It can greatly reduce
customer’s DTU procurement and integration cost, and has
industrial-grade stability and reliability as well. MD-309 has more
reasonable cost control, with lower price; it has more plentiful
interfaces and ways of software integration; it can be regarded by
customers as an easy-to-use and useful 2G DTU product.
It can connect with mServer, and other kinds of data center software
as well;
It supports China Mobile and China Unicom’s 2G, and China Telecom’s
CDMA networks;
The serial port DB9 pins support RS232 and RS485 at the same time,
and the serial port type(RS232 or RS485) can be configured via
DTU configuration software or remote control;
1
It can be used without shell, and on the switch board there are
preserved data and power interfaces (pin socket);
The size without shell is smaller, and there are preserved installation
holes that can be easily integrated into customer’s device;
It supports use cases such as point to point, point to multiple points,
and serial to serial port;
It uses industrial components and can be used in adverse environment;

It can work within -35ºC ~+70ºC temperature range.
MD-309 can connect quickly with RTU, PLC, or IPC, and implement
remote and transparent data transfer. It can be used widely in various
industries related to “Internet of things”:
In electric power industry, MD-309 can be used in data transfer areas
such as reactive compensation, distribution monitoring, electric meter
reading and lamp monitoring;
In water application industry, MD-309 can play in wireless
communication areas such as water meter reading, water resource
remote monitoring, and water transportation network monitoring;
In environment protection area, MD-309 can fully deserve 2G soldier in
pollution online monitoring system such as Continuous Emission
Monitoring System(CEMS), water quality monitoring system;
In device maintenance area, such as elevator monitoring and
air-conditioner monitoring, MD-309 can be embedded quickly into
customer’s appliance and implement 2G wireless data transfer;
In heating industry, MD-309 can connect with MODBUS concentrator to
implement heating meter reading, implement remote data transfer for
household heating measurement; it can also connect with PLC or
collector to implement remote monitoring of heat exchange station.
