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:

2 Installation and Test
2.1 Installation
Before testing 200F, connect both serial and Ethernet port to your PC. It will be no
problem that the Ethernet connection includes network hubs.
Fig 2-1 connection between 200F and a PC
Procedures for the test are followed.
2.1.1 Setting Network Aera
This step is for setting both EZL-200F and users’PC to be located the same network. If
only they are, the TCP connection between them can be established.
Setting of the PC
Add or change the IP address of the network adapter on your PC like following.
Get into the menu of [Windows Control Panel] >> [Network Connections] >>
[Properties of the Network Adapter –with right click of your mouse]. Then, you can
show the properties of [Internet Protocol (TCP/IP). In there, press the [Advanced..]
button for adding an IP Address like the below figure.
Fig 2-2 adding / changing the IP address of users’PC

EZL-200F User’s Manual Ver. 2.1
Sollae Systems Co., Ltd. - 12 - http://www.sollae.co.kr
Setting of EZL-200F
EZL-200F uses ezConfig as it’s a configuration program. ezConfig is for MS Windows,
and this is comfortable to use because it doesn’t need installation. First, search your
EZL-200F via network. All the values of parameters were set to default values in the
factory. To apply it to your system, proper values should be set via ezConfig. Major
parameters’default values are listed on below table. To implement this simple test,
keep these values without any changes.

④An example
When you input a command and module, each available parameter appears one by
one. You can set values directly or use “y”and “n”in some options. If one or more
parameters are changed, EZL-200F stores the setting and reboots automatically after
the last parameter.
Fig 3-4 configuration by TELNET console
3.2.2 Using Serial Port
Checklists
The connection between PC and product with a RS232 crossed cable is needed and
the console mode has to be running. Then, open the COM port by using serial
terminal program.
Procedures
