WaveShare

WaveShare RS232 to RJ45 Ethernet Device Server, Industrial Rail-Mount

SKU CH-YW47-EE47A

Industrial RS232-to-Ethernet gateway with Modbus, MQTT and JSON conversion for rail-mount data acquisition

  • Industrial rail-mount design simplifies DIN-rail installation
  • Bi-directional RS232 to Ethernet transparent data transmission
  • Modbus gateway support enables legacy protocol integration
  • Multi communication modes include TCP Server, TCP Client, UDP and UDP Multicast
  • MQTT and JSON conversion adds flexible protocol bridging

RS232-to-Ethernet industrial gateway

This WaveShare device server converts RS232 serial data to Ethernet for industrial monitoring and data acquisition. It combines serial server, Modbus gateway, MQTT gateway and RS232-to-JSON functions in a rail-mount module with screw-terminal power input.

Ideal for legacy serial integration.

Engineers adding Ethernet to PLCs, meters or sensors over Modbus TCP or MQTT will benefit. Buyers needing native USB, Wi-Fi, Bluetooth or fibre connectivity should look elsewhere.

Bi-directional transparent transmission at 232

The module moves data both ways between the RS232 port and the RJ45 link using TCP server, TCP client, UDP or UDP multicast modes, with multi-host roll-polling to prevent crosstalk.

Questions about this item

How do I confirm the RS232-to-Ethernet link is passing data correctly after wiring it up?

Connect the RS232 device and Ethernet cable, power the module, then use the configuration software to verify transparent transmission and Modbus gateway operation.

What comes in the box and what must I source separately?

The rail-mount module with RS232 and RJ45 ports is included; you must supply a DC power source for the screw terminals and an Ethernet cable.

Which communication mode should I select for my Modbus gateway application?

Choose TCP Server, TCP Client, UDP or UDP Multicast mode depending on your network topology; the module also supports MQTT and JSON-to-Modbus conversion.
