CP202-2CI is a CAN server that has integrated 2 CAN ports and 1 Ethernet port. It can implement interconnection between CAN-Bus network and Ethernet to further extend the communication range of CAN-Bus network. This product supports 2 CAN to 1 100M Ethernet copper port and adopts wall mounting which can meet the requirements of different scenes.

CAN server supports multiple network protocols, such as TCP, UDP, TELNET, ARP, ICMP, HTTP, DNS and DHCP protocols. It possesses complete management function, like access control, quick configuration, online upgrade, etc. Each CAN supports 4 TCP or UDP sessions, and multiple operating modes like TCP Server, TCP Client, UDP Server, UDP Client, UDP Rang and UDP Multicast. Access methods such as TELNET, WEB are also supported. The network management system could bring you great user experience via its friendly interface design and easy and convenient operation. 

DEF button could implement restoring to factory setting for device. Hardware adopts fanless, low power consumption, wide temperature and voltage design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It can be widely used in PLC control and management, building automation, healthcare automation system, measuring instrument and environment monitoring system, etc.
