CSE-H21 is a serial-Ethernet converter which has two serial ports.
CSE-H21 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-H21 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-H21, 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. Especially CSE-H21 supports wide range operating temperature (-40∩ ~ +70∩) and its serial ports are isolated electronically.So CSE-H21 can be used in industrial noisy environments.
