Cport3101R is a din-rail 1* RS232/485 Ethernet serial server, using a 32-bit Arm Cortex-M7 core, with the main frequency up to 400MHz, and an external hardware watchdog design. The power supply, network port, and serial port all have high-level ESD, surge and EFT protection, strong anti-interference ability, and are designed to provide data transmission between serial port and Ethernet for industrial users. This product supports 1xRS232/485/422 serial port and 1x100Mbps copper port. It integrates the TCP/IP protocol stack internally, making it convenient, flexible, and fast to connect to Ethernet for RS232/485/422 devices. This industrial grade Ethernet serial server supports WEB configuration for various network management functions, such as serial/ethernet working mode, DNS, network logs, serial port restart, system management, etc. It supports conversion modes of UDP/UDP Multicast, TCP Client/Server, Modbus RTU Master/Slave, Modbus ASCII Master/Slave, RealCOM_MCP/CCP/CS, Pair Connection Master/Slave, HTTPD Client and WebSocket Client, to convert serial ports to Ethernet or Modbus TCP protocol. In terms of core components, this product adopts an industrial grade quality design scheme, which has many advantages such as wide temperature and pressure, lightning resistance, electromagnetic interference resistance, high reliability, high performance, and suitability for operation in harsh environments. It can be used in industrial monitoring, traffic management, meteorology, water treatment, environmental monitoring, coal mining, petroleum, chemical, new energy and other industries, for remote on-site data collection, remote monitoring, on-site control, etc. It is an essential industrial communication product for the development of industrial Internet of Things.
