## Features

- RS485 to RJ45 Ethernet Module with POE Function, Bi-Directional Transparent Data Transmission Between RS485 and Ethernet. Rail-mount support, easy to combine multi rail-mounted serial server together, more freely.
- Multi communication modes, supports TCP server / TCP client / UDP mode / UDP multicast. 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.
- Support Modbus gateway function,suitable for Modbus gridding upgrade, can be used with 3D configuration software. Support Modbus RTU to Modbus TCP. It can support storage-type Modbus, and can automatically collect device data and store it; it also supports a non-storage mode Modbus gateway. Support JSON to Modbus RTU and 645-meter protocol, support HTTP POST, and HTTP GET format to upload data.
- Support custom heartbeat package and registration package function: It is convenient to communicate with the cloud and identify devices. It supports the function that password authentication is required to establish a connection through TCP to ensure connection security. It supports the function of data submission and delivery in HTTP mode, and the cloud can directly use the HTTP GET command to interact with the serial port data of the device.
- Support Web browser configuration, support DHCP to obtain IP dynamically, and DNS protocol to connect domain name server address. Support cloud remote search for devices, the configuration of device parameters, and device program upgrades. Support remote viewing of the device's TCP connection status, and serial port data sending and receiving status through software. The virtual serial port supports the data monitoring function.
