    The serial communication is quite simple to implement but has weaknesses like short distance and hard maintenance. CSW-H80 lets the serial devices connect to the Internet via wireless LAN (IEEE802.11b/g). To communicate on the Internet, devices should use TCP/IP protocol, so CSW-H80 processes the converting serial data to TCP/IP.

  • Page 31: Communication Modes

    Communication Modes 5.1 TCP Server In this mode, CSW-H80 functions as a TCP server. CSW-H80 listens to a TCP connection from remote host. Once a host tries to connect to CSW-H80, it responses that request. After the connection is established, CSW-H80 converts the raw data from the serial port to TCP/IP data and sends them to the network and vice versa.
