  • Page 6: Overview

    The serial communication is quite simple to implement but has weaknesses like short distance and hard maintenance. CSE-H53N lets the serial devices connect to the Internet. To communicate on the Internet, devices should use TCP/IP protocol, so CSE-H53N processes the converting serial data to TCP/IP.

  • Page 28: Communication Modes

    Communication Modes 5.1 TCP Server In this mode, CSE-H53N listens to a TCP connection request from remote hosts. Once a host tries connecting to CSE-H53N, it accepts a connection. After the connection is established, CSE-H53N converts the raw data from the serial port to TCP/IP data and sends it to the network and vice versa.
