Special Features

  • This is a multi-functional device data acquisitor / IoT gateway with 4-ch RS485 and an Ethernet port, small in size, easy to install, and cost-effective. Bi-directional transparent data transmission between 4-Ch RS485 and Ethernet.
  • 4-ch RS485 can work independently without affecting each other at the same time, enabling more effective data transmission.
  • Combines multiple functions in one, including serial server, Modbus gateway, MQTT gateway, and RS485 to JSON, etc. 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. 【Multi configuration methods】Supports Web browser configuration, obtaining dynamic IP via DHCP, DNS protocol connected domain server address.
  • 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, lightningproof & 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
