The ezTCP CSE-H21 2-port industrial serial to Ethernet converter is designed for manufacturing and industrial applications that want to quickly and easily add Ethernet connectivity to their system.
The CSE-H21 has two RS232 ports to enable Ethernet network connectivity of your RS232. Not only can you reduce cost and risk, but you can also shorten development time to add the network capability.
Because the CSE-H21 allows you to extend the distance of your serial communication system, you can remotely control and monitor the serial devices over the Internet regardless of distance. With advantages such as stable performance, noise resistance, surge protection circuitry and two electrically isolated RS-232 ports, the CSE-H21 is suitable for many industrial and manufacturing sites.
The CSE-H21 RS232 to Ethernet Network Device Server can be used in diverse applications such as Advertisement and Signage Systems, Remote Weather Monitoring Systems, and Control PLC over Internet.
