Overview
B1-Cport3101-I is an industrial-grade Ethernet serial server designed for seamless data transmission between serial devices and Ethernet networks. Featuring a 32-bit Arm Cortex-M7 core with a main frequency of up to 400MHz, this device ensures high-speed and reliable connectivity.
With its external hardware watchdog design and high-level ESD, Surge, and EFT protection on the power supply, Ethernet port, and serial port, the B1-Cport3101-I offers strong anti-interference capabilities, ideal for industrial environments. It supports 1xRS232/485/422 serial port and 1x100Mbps copper port, enabling efficient data transmission.
This Ethernet serial server integrates the TCP/IP protocol stack internally, providing convenient and fast connectivity for RS232/485/422 devices. It supports various network management functions, including serial/network working mode, DNS, network logs, and serial port restart, via WEB configuration.
Additionally, the B1-Cport3101-I supports conversion modes such as UDP/UDP Multicast, TCP Client/Server, Modbus RTU Master/Slave, Modbus ASCII Master/Slave, RealCOM_MCP/CCP/MW, Pair Connection Master/Slave, HTTPD Client, and WebSocket Client, facilitating versatile connectivity options.
Built with industrial-grade quality components, the B1Cport3101-I is designed to withstand harsh environments, offering wide temperature and pressure tolerance, lightning resistance, and electromagnetic interference resistance. It is suitable for a wide range of industries, including industrial monitoring, traffic management, meteorology, water treatment, environmental monitoring, coal mining, petroleum, chemical, and new energy.
With its ability to provide remote on-site data collection, remote monitoring, and on-site control, the B1-Cport3101-I is an essential industrial communication product for the development of the Industrial Internet of Things (IIoT). Backed by a 1-year warranty and free lifetime technical support.
