Modbus is not supported. M0 series 32-bit ARM processors are fast and efficient. 10/100M Auto-MDI/MDIX Ethernet interface supports both crossover and straight-through cables. Configurable RS485 baud rate (600 bps to 230.4 kbps) with five parity options: None, Odd, Even, Mark, Space. Available working modes: TCP Server, TCP Client, UDP Server, UDP Client, HTTP Client (supports GET and POST). Configuration via web interface, AT commands, serial port protocols, and network protocols. Includes configuration protocols for integration into custom software. Supports custom heartbeat packets to verify active connections and actively retrieve sensor data. Supports custom registration packets to uniquely identify devices upon connection. Supports custom web pages for module configuration. Compatible with RFC 2217–like protocols for dynamic serial port parameter changes (e.g., baud rate, data bits). Keep-Alive mechanism detects disconnections and triggers automatic reconnection. Timeout-based restart (restart if no data is received) ensures long-term stable operation; restart interval is configurable. Supports DNS domain name resolution with configurable DNS server. Supports DHCP, static IP, and automatic IP assignment. Firmware can be upgraded over the network. Factory reset available via software and/or hardware. Default MAC address included; customizable. Provided software includes module configuration utility, TCP/UDP test tool, and VCOM virtual serial port software. Sample code available for host (socket), VB, C++, Delphi, Android, and iOS. Plug Type: US Plug — compatible with Canada, India, Mexico, Taiwan, Thailand, United States, Philippines, etc. Type: Converter Processor: Cortex-M0 Serial Interface: RS485 Form Factor: Industrial RS485 to RJ45 Function: RS485 to RJ45 Ethernet Converter
