2 ports rs232 to ethernet tcp ip converter cse h21

CSE-H21 is a 2 ports industrial serial to Ethernet converter that provides your serial equipment with seamless network connectivity. By applying it, therefore, you can remotely control and monitor your serial equipment over network without changing legacy system. This serial to Ethernet converter ensures stable performance in spite of noise in industrial environments since it is equipped with a surge protection circuit and two of electrically isolated RS232 ports.

CSE-H21 can be used in various communication environments such as Internet LED Displays, Remote Weather Monitoring System, Control PLC over Internet, etc.
