Realize RS232/485/422 to Ethernet bidirectional transparent transmission function

Onboard RS232 / 485 / 422 three serial ports, suitable for more application scenarios

Ethernet port to RS232 / 485 / 422

The network port can send data to three serial ports at the same time

RS232 / 485 / 422 to Ethernet port

At the same time, only one serial port interface can be selected to send data to the network port

Supports PoE Power over Ethernet for IEEE 802.3af PoE standard

Support terminal block and DC 5.5 power interface for power supply, DC 6~36V wide voltage range input

Industrial grade guide rail design, small size, easy installation, high cost performance

Network upgrade suitable for Modbus, compatible with 3D force control modal components

Support TCP server / TCP client / UDP mode / UDP multicast

Multiple protocol conversion more freely

When used as an MQTT gateway, the device can upload serial port data to the MQTT server using the MQTT protocol through transparent transmission. The supported servers include Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet platform, etc. It supports parsing the collected Modbus RTU or non-standard serial port data into JSON format, encapsulating them in MQTT packets and uploading them.

When used as a JSON data acquisition gateway, the device can be connected to the data acquisition instrument through RS485, and then automatically collect data and convert it into JSON format and send it to the server. The collected data supports Modbus RTU 645 instrument version 97, 645 instrument version 07, and various non-standard RS485 protocols. Users can configure the uploaded data format through the host computer, and JSON upload can support protocols such as MQTT protocol, HTTP POST protocol, and HTTP GET.

It can identify data sent by different network devices and respond accordingly to prevent data misalignment. Effectively solve the problem that the serial port device replies to the wrong position after multiple network devices send data at the same time

Custom heartbeat package and registration package can facilitate communication with the cloud and device identification

Obtain network time for serial port output or for protocol content upload

Support Web browser configuration, support DHCP to obtain IP dynamically,DNS protocol connection domain name server address

On-board power supply and signal double isolation, can provide stable isolation voltage, high reliability, strong anti-interference; built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightning protection Static electricity; built-in resettable fuse and protection diode to ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve shock resistance

The shell is made of aluminum alloy and is treated with anodizing and frosting

Strong and durable, better appearance and feel
