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 open TCP/IP in public 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.

CSE-M32 in ezTCP product group is a product that provides TCP/IP communication

through Ethernet. In other words, like other ezTCP products, CSE-M32 sends data from the

serial ports to the LAN after TCP/IP processing and vice versa.

As CSE-M32 has 2 UART ports so that it supplies TCP/IP functions to two UART devices.

And because one UART port support the TCP speed of about 1.8Mbps, CSE-M32 is very

useful for the high speed communication device.

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.
