MD-649 4G Wireless Data Terminal
| MD-649 4G DTU Introduction |
|
MD-649 is an industrial 4G LTE DTU product, and has capability of high-speed data transfer. It completely supports 2G/3G/4G networks. In LTE 4G network, the maximum downlink speed can reach 100Mbps, and uplink speed can reach 50Mbps. Therefore, MD-649 4G DTU is much suitable in application for big size data transmission. 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 4G DTU product.
1）It completely supports 2G/3G/4G networks;
2）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;
3）It can connect with mServer, and other kinds of data center software as well;
4）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;
5）It supports use cases such as point to point, point to multiple points, and serial to serial port;
6）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”:
1）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;
2) 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;
3) 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;
4) 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;
5) 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.

| Working Mechanism |
 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. |
