Function Block
Basic Funstion
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 of 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, and actively collect data when sent to the serial terminal.
The contents of registration package and heartbeat package, heartbeat interval can
be modified by AT command.
Designed with Qualcomm MDM9205 communication module
Parameter Configuration
Support the parameter configuration of serial,
network and SMT AT commands, and provide the configuration tool for the PC.
Remote FOTA Upgrade
With the remote management platform,
it can realize the automatic firmware upgrade
Have a small upgrade package of differential algorithm,
and this can save upgrade traffic and time.
Application Cases of Vehicle Monitoring
MB706 can upload the vehicle information to the cloud, 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 electric system and demand response to
reduce peak loads, prevention of outages.Through the connection with MB706, all the serial data will be sent to
SCADA software via LTE CAT M1 and NB-IoT network.
