Function Block
Basic Function
USR-MB706 quickly delivers the bi-directional transparent transmission of data at serial ports and networks.
Modbus RTU to TCP
Modbus RTU/Modbus TCP protocol conversion for industrial SCADA systems and field devices.
Supports GNSS and positioning information reporting
USR-MB706 supports multiple positioning modes, including GPS, beidou, glonass and galileo, which can be configured by AT commands and output the positioning format comparable to international standards.
Registration Package plus Heartbeat Package
The registration packet is sent to the server to identify the device. The heartbeat packet is used to judge the active state of the device when sent to the server, which will actively collect data when sent to the serial terminal. The contents of registration package, heartbeat package, as well as heartbeat interval can be modified by AT command.
Designed with Qualcomm MDM9205 communication module
Parameter Configuration
Supports the parameter configuration of serial, network and SMT AT commands, and provide the configuration tools for the PC.
Remote FOTA Upgrade
With the remote management platform, it can realize the automatic firmware upgrade. Besides, there exists a small upgrade package of differential algorithm, and this results in the saving of upgrade traffic and time.
Application Cases of Vehicle Monitoring
MB706 can upload the vehicle information to the cloud, and the cloud monitoring personnel can monitor the vehicle status in real time to achieve intelligent process management.
Meter Reading
Smart meters are crucial components of the Smart Grid and enable two-way communication by interfacing remotely with the utility and deliver meter readings automatically. By gathering and forwarding data, smart meters allow consumers to make informed decisions to alter usage and optimize electricity consumption. It also helps utilities to better monitor the electrical system and demand response to reduce peak loads, and prevent outages. Through the connection with MB706, all the serial data will be sent to SCADA software via LTE CAT M1 and NB-IoT network.
