RS485 TO ETH ( B)
1 . OVERVIEW
It is a UART to Ethernet module designed for industrial environments, small in size, easy to
embed and integrate, with device data collector/IoT gateway, serial server, Modbus gateway, MQTT
gateway, UART to JSON, and many other functions in one. It has a UART interface and an Ethernet
interface.You can directly integrate it into the device application of your own UART/RS232/RS485
port
When used as a common serial port server, connect the UART TO ETH (B) network port to
the Ethernet, and the host computer software can use TCP/ UDP transparent transmission or
virtual serial port mode to send data to UART TO ETH (B) On the UART interface; the data
received on the UART interface will also be transmitted to the software or virtual serial port on
the TCP side. In the virtual serial port mode, the serial port software connected to the virtual
serial port can be used without any need.
When used as a Modbus gateway, UART TO ETH (B) supports Modbus TCP to Modbus RTU,
so that the host computer uses Modbus TCP protocol to collect data from UART/RS485
Modbus RTU devices. On the contrary, if the UART/RS485 terminal is used as the master
station, it can also be used. The supported multi-master function allows multiple computer
masters to access an RS485 slave device at the same time. In this application scenario, you need
to add some TTL to RS485 circuits, or use our ready-made RS485 to network port modules, such as
RS485 TO ETH (B), RS485 TO POE ETH (B),etc.
When used as an MQTT gateway, the device can transparently upload serial port data to the
MQTT server using the MQTT protocol. Supported servers include Baidu Cloud MQTT, Alibaba
Cloud MQTT, China Mobile OneNet platform, etc. Support to parse the collected Modbus RTU or
non- standard serial port data into JSON format, encapsulate it in MQTT data package and upload
it. Support JSON format to upload collected data, automatic data collection, collected data
support Modbus RTU, 645 meter 97 version, 645 meter 07 version, various non-standard RS485
protocols. Users can configure the uploaded data format and JSON keywords with Vircom. When
uploading, it can support MQTT protocol, HTTP POST protocol, HTTP GET protocol, transparent
transmission protocol, and various non-standard network protocols. RS485 TO ETH (B) has
various functions of a powerful IoT gateway, which is very suitable for collecting various RS485
instruments and sensors in the industrial field, including local network collection or uploading to
the cloud server.
UART/RS485 TO ETH (B) can be applied to
：
As a gateway of the Internet of Things as a communication bridge between the device and
the cloud;
