This PoE RJ45 Ethernet Module transmits bi-directional transparent data between RS232 and the RJ45 ethernet connection. It has many forms of communication, including TCP Server / TCP Client / UDP Mode / UDP Multicast. There is a more flexible conversion between different protocols with its MQTT/JSON To Modbus feature and a Modbus gateway support that is suitable for a Modbus gridding upgrade, that can be used with specific configuration software.

With its multi-configuration methods, NTP protocol support (used to synchronize with computer clock time sources in a network) Multi hosts roll-polling support, screw terminals for power support, a rail mount case design to combine multi-rail mounted serial servers together, and small in size for easy installation. This module is great for your transmitting and communication needs.


  • TCP server, TCP client, UDP mode, and UDP multicast. As a TCP client, it also supports TCP server-side functions. Supports 30 TCP connections as a TCP server and 7 destination IPs as a TCP client.
  • Baud rate of 1200~115200bps, the data bit supports 5~9 bits, and the parity bit can be no check, odd check, even check, mark, or space.
  • Sends MAC address on device connection, which is convenient for cloud management of devices.
  • Secondary development kit DLL development library for computer-side searchand cofiguration of devices.
  • Web browser configuration, support DHCP dynamic acquisition of IP, DNS protocol connection name server addresses.
  • Remote search for devices, configure device parameters and upgrade device demos in the cloud.
  • Remote viewing of the TCP connection status, serial port data sending, and receiving the status of the device through software. The virtual serial port supports the data monitoring function.
