RS232/RS422/RS485 to RJ45 Ethernet Module, TCP/IP to Serial, Bi-Directional Tran

This is a RS232/485/422 device data acquisitor / IoT gateway designed for industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, etc
Bi-directional transparent data transmission between RS232/485/422 and Ethernet. The module features RS232/485/422 and Ethernet port, uses
DC port (outer diameter: 5.5 mm, inner
diameter: 2.1 mm) and screw terminals for power input
Onboard RS232 / 485 / 422 Interfaces, Suitable For More Application Scenarios. Only one of the RS232, RS485, and RS422 can send data to the Ethernet port at the same time
Modbus Gateway Support: Suitable for Modbus networking upgrade, Can Be Used With specific Configuration Software.
Multi hosts roll-polling support: Different network devices will be identified and responsed respectively, no more crosstalk issue while communicating with multi network devices
Onboard power supply and signal isolation, it can provide stable isolation voltage with high reliability and strong anti-interference. Built-in TVS can effectively suppress the surge voltage and transient peak voltage in the circuit, light-ningproof & ESD protection. Built-in resettable fuse and protection diode to ensure stable output of current and voltage, prevents over-current and over-voltage proof, improve shock proof performance
