WaveShare RS232/RS485 to Ethernet Converter

M4 series 32-bit ARM processor with a frequency of up to 120 MHz, offering fast speed, stability, and reliability. 10/100M Auto-MDI/MDIX Ethernet interface, compatible with both crossover and straight-through cables. Both RS232 and RS485 interfaces allow for independent operation simultaneously without interference.

Configurable baud rate (600 bps to 230.4 Kbps) supports five parity check options: none, odd, even, mark, and space. Multiple indicators are available to monitor communication and operational status.

Supports Modbus, suitable for industrial applications. Supports WebSocket, enabling bidirectional transparent data transmission over the RS232/RS485 port directly through a web page.

Supports customizable heartbeat packets to ensure a reliable connection, as well as for actively querying sensor data. Supports customizable registration packets that automatically pass the registered packet as an identifier after the connection is established, allowing for differentiation between devices.

Supports a customizable web page that allows users to modify the module configuration page. Supports an RFC2217-like protocol capable of communicating with devices whose serial settings (baud rate, data bits, etc.) may change.
