Product details
M4 series 32-bit ARM processor with up to 120MHz frequency, fast speed, stable and reliable. 10/100M Auto-MDI/MDIX ethernet interface, regardless of cross-over or straight-through cable. Both RS232 and RS485 interfaces allow for independent operation at the same time without interference.
Configurable baud rate (600bps to 230.4Kbps) supports five parity check options: none, odd, even, mark, and space. Multiple indicators are available for monitoring communication and working status.
Supports Modbus, suitable for industrial applications. Supports WebSocket, allowing bi-directional transparent data transmission with RS232/RS485 port via webpage directly.
Supports customized heartbeat packets to ensure the connection is reliable, as well as for actively retrieving sensor data. Supports customized registration packets, automatically passing the registered packet as an identifier after the connection is established, enabling differentiation between devices.
Supports a customized webpage, allowing users to customize the module configuration page. Supports RFC2217-like protocol, capable of communicating with devices whose serial settings (baud rate, data bit, etc.) may change.
