• This is a multi-functional device data acquisitor / IoT gateway with 4-ch RS485 and an Ethernet port with POE, 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.
• Multi Power Supply Options--- Support PoE Ethernet port power supply, Suitable for IEEE 802.3af PoE standard. Support Screw Terminal for Power Supply, DC 6~45V Wide Voltage Range Input .
• 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
