Cport3101R-485 is a Modbus RS485 to Ethernet converter designed for stable, transparent, bidirectional communication between RS485 serial devices and Ethernet networks. Built on an ARM Cortex-M0 processor, it delivers high-speed data processing with low power consumption and excellent reliability—ideal for industrial IoT and automation systems.
This compact converter supports multiple working modes including TCP Server/Client, UDP Server/Client, HTTPD Client, and Modbus TCP, allowing flexible integration into existing networks. Configurable via web interface, AT commands, serial or network protocols, it enables seamless deployment and remote management.
Key features include:
10/100Mbps RJ45 Ethernet port with Auto-MDI/MDIX
Wide baud rate range (600bps–460.8Kbps) and multiple parity options
Custom heartbeat & registration packets for connection stability
Up to 8 TCP clients, with kick-old-client option
DHCP, DNS support, and globally unique MAC address
Automatic reconnection, timeout restart, and short TCP connection support
-40°C to +85°C industrial-grade operation temperature
Firmware upgradeable via web and configurable to work through gateways, routers, or LAN/WAN environments
With robust industrial protection and global MAC registration, Cport3101R-485 is ideal for industrial automation, energy systems, smart cities, machine integration, and remote monitoring applications.
