Description

--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: 5.5mm, inner diameter: 2.1mm) 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 (transient voltage suppression tube) 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.
