Waveshare Industrial RS232/RS485 to Ethernet Converter (EU)

Waveshare Industrial RS232/RS485 to Ethernet Converter

The RS232/485 TO ETH is an industrial RS232/RS485 to Ethernet converter, which allows bi-directional transparent data transmission between RS232/RS485 and RJ45 port Ethernet, even at the same time. It can be configured via a webpage, AT commands, serial protocol, and network protocol provides configuration protocol that can be integrated into your own software.

It supports customized heartbeat packets and customized registration packets which makes sure the connection is truthful, as well as actively retrieving sensor data and auto passing the registered packet as identifier after the connection is established so that different devices can be distinguished.

The RS485 to Ethernet Converter comes with several working modes such as TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client (supports GET and POST). etc.

How to Use Waveshare Industrial RS232/RS485 to Ethernet Converter

Power the unit using a 5–36 V supply, then connect your serial device to the RS232 or RS485 terminal block. Plug the Ethernet port into your network switch or router. Access the converter’s web interface by entering its default IP in your browser, configure communication parameters (baud rate, mode, IP), save settings, and reboot. The device will then transparently forward serial data over Ethernet.

Frequently Asked Questions

Can I use both RS232 and RS485 interfaces simultaneously?

No. This converter provides a selectable interface—either RS232 or RS485—at any given time. Use the onboard switch or web settings to choose the required mode before operation.

How do I assign a fixed IP address to the converter?

Log into the web configuration page using the default IP, navigate to Network Settings, switch from DHCP to Static, enter your desired IP, subnet mask and gateway, then save and reboot. The unit will come up with the assigned address.

What is the maximum serial baud rate supported?

The converter handles serial data rates up to 230.4 kbps, accommodating slow sensors and high-speed devices alike. Configure the baud rate via the web UI or AT command interface.
