1 Overview

1.1 Overview

Almost all communication devices including PC are using serial transmission. In this type,

devices send and receive data in the order of each byte. The serial communication is quite

simple to implement but has weaknesses like short distance and hard maintenance.

EZL-200F lets the serial devices connect to the Internet. To communicate on the Internet,

devices should use TCP/IP protocol, so EZL-200F processes the converting serial data to

TCP/IP.

EZL-200F supports RS-422 and RS-485 as well as RS-232 including the Telnet COM Port

control option (RFC2217), SLIP (Serial Line Internet Protocol) and etc. Furthermore, MIC real

time operating system developed by Sollae Systems is loaded.

1.5.2 Ethernet Interface

Since part of EZL-200F network is composed of Ethernet, UTP cable may be connected. It

will automatically sense 10Mbits or 100Mbits Ethernet and connect itself. It also provides

auto MDI/MDIX function that can automatically sense 1:1 cable or cross over cable.

Each Ethernet device has its own unique hardware address. The hardware address of EZL-

200F is set in the factory before being shipped to the market. (The hardware address is also

known as the MAC address)

Fig 1-6 the Ethernet interface

1.5.3 Power

DC5V is used for the power. The specifications of the power jack are as the following:
