CSE-H20 is a serial-Ethernet converter which has two serial ports.

CSE-H20 is a serial-Ethernet converter which has two serial ports. It adds network connectivity to your devices by processing TCP/IP protocol which is required to send and receive data over the Internet. CSE-H20 also makes it possible to extend the distance of serial communications without any change of your legacy systems or replace direct serial connection. This is a simple and easy way to bring the advantages of remote control and management to your serial devices not connected to a network. By using CSE-H20, your devices can be remotely controlled, managed and monitored over the Internet. Because of its robust TCP/IP stack, it is ideal for various applications.
