1 Overview

1.1 Overview

Along with the development of the Internet, the demand for data communication functions has

increased recently. Data communication over the Internet requires using TCP/IP, the Internet

communication protocol. That is to say, in order to connect a system to the Internet, TCP/IP

protocol must be implemented. It is possible to implement TCP/IP by directly implementing the

protocol, porting public TCP/IP, or using Operating System (OS). However, all these methods

impose burdens on the developer in time, cost, and technology.

ezTCP series, a Serial ↔ TCP/IP protocol converter product group of Sollae Systems, enables

you to use TCP/IP communication (the Internet communication) function simply by “connecting

the cable to a serial port”. ezTCP sends data from the serial port to the Internet network after

TCP/IP processing, and vice versa.

CSW-H80 in ezTCP product group is a product that provides TCP/IP communication through

wireless LAN (IEEE802.11b/g). In other words, like other ezTCP products, CSW-H80 sends data

from the serial port to the wireless LAN after TCP/IP processing and vice versa.

As CSW-H80 has an SMA antenna port and it is a compact size product, it is easy CSW-H80 to

attach to user systems.

It provides DHCP and PPPoE functions, so that it can be applied to the cable network and the

xDSL network. And it has DDNS(Dynamic DNS) function, so it can be used more easily in the

internet.

It also provides debugging function, so user can solve the problem with ours.
