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.

EZL-200L in ezTCP product group is a product that provides TCP/IP communication

through Ethernet. In other words, like other ezTCP products, EZL-200L sends data from

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

It provides DHCP and PPPoE functions as well as TCP/UDP/IP, so that it can be applied

to the cable network and the xDSL network.

EZL-200L is low-cost TCP/IP solution that is integrated highly and optimally in a small

hardware.

1.4.4. Ethernet Interface

The interface of EZL-200L is 10Base-T. 1:1 cable should be used for connection with a

HUB and cross-over cable should be used for connection with PC directly without any

HUB.

1.4.5. Ethernet Address (MAC address)

Each piece of Ethernet equipment has unique hardware addresses, and EZL-200L also

has factory-set hardware address (which is called MAC address). The address is printed

in bottom of EZL-200L.
