1.1 Brief Introduction
MD-649 is a 4G DTU produced by eTung in 2015. Compared with
traditional GPRS DTU, MD-649 works in 4G network, and has
capability of high-speed data transfer. It completely supports China
Mobile，China Unicom and China Telecom’s 2G/3G/4G networks. In
LTE 4G network, in theory the downlink speed can reach 100Mbps,
and uplink speed can reach 50Mbps. Compared with China Unicom’s
WCDMA 3G network(downlink speed 14.4Mbps and uplink speed
5.76Mbps), the speed of 4G network is 10 times higher than WCDMA
3G network. Therefore, MD-649 4G DTU is much suitable in occasions
that have large quantity of data transfer or have high real-time
property.
MD-649 has built-in industry-level 4G module, with data transfer
more stable and efficient. It has more flexible interfaces and ways of
software integration; it can be regarded by customers as an
easy-to-use and useful 4G DTU product.
It completely supports China Mobile, China Unicom and China
Telecom’s 2G/3G/4G 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;

It can connect with mServer, and other kinds of data center
software as well;
It can be used without shell; 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 -40ºC ~+85ºC temperature range.
MD-649 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-649 can be used in data transfer
areas such as reactive compensation, distribution monitoring,
electric meter reading and lamp monitoring;
In water application industry, MD-649 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-649 can fully deserve 4G
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-649 can be embedded quickly into
customer’s appliance and implement 4G wireless data transfer;
In heating industry, MD-649 can connect with MBUS 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.

1.5 Working Mechanism
Figure 1-9: MD-649 working mechanism
After configuring IP address (or domain name) and port of the data
center in MD-649, it dials in 4G wireless network to access the internet;
then it establishes connection to the preconfigured IP address and
port(i.e. mServer's listening port). On the other hand, the user
software system connects to the mServer via virtual serial port, thus
implements the wireless and bi-directional data communication
between user device and user software system.
