Overview 

1.1

 

Overview 

Almost all communication devices including a PC are using serial communication. Devices 

transmit and receive data in bit order in the serial communication which is quite simple to 
implement but has weaknesses such as short distance and hard maintenance. 

CSW-H80  is  a  converter  that  enables  serial  devices  to  support  TCP/IP  communication 

through wireless LAN. CSW-H80 carries out the converting process to help users get to the 
network using TCP/IP protocol.   

 

1.2

 

Features 

 

Connect serial devices to IEEE 802.11b/g wireless LAN 

 

RS232 Interface 

 

SMA Male connector for an external antenna 

 

Stable embedded TCP/IP stack 

 

Easy configuration program (ezManager)Application Examples
