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.
CSE-H55 lets the serial devices connect to the Internet. To communicate on the Internet,
devices should use TCP/IP protocol, so CSE-H55 processes the converting serial data to
TCP/IP.
1.2 Features
RS422/RS485 (Terminal Block)
Industrial temperature range (-40℃ ~ +85℃)
Variety of monitoring status (ezManager, TELNET)

1.6 Interfaces
1.6.1 Serial Interface
CSE-H55 has a serial port for user serial device (300bps ~ 230,400bps). This port is
interfaced with 4-pins terminal block and the each pin should be fixed by a flat-head
screwdriver driver.

1.6.2 Ethernet Interface
Since part of CSE-H55 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 CSE-
H55 is set in the factory before being shipped to the market. (The hardware address is also
known as the MAC address)

1.6.3 Power
DC 5V is used for the power. The specifications of the power jack are as the following:

1.7.1 ISP Switch
There is a switch, which is named ISP switch (or button) located on the side of the
product. You can change the operation mode of CSE-H55 to ISP or Serial Configuration
mode with this switch.

2 Installation and Test
2.1 Installation
Before testing CSE-H55, users should connect both serial and Ethernet port to a PC. To
connect the RS232 port of your PC and CSE-H55 via serial, you need a RS232 to 422/485
converter. It will be no problem that the Ethernet connection includes network hubs.
 In case if your PC doesn’t have a RS232 port, use a USB to RS232 cable.
Figure 2-1 connection between CSE-H55 and a PC
Procedures for the test are followed.
2.1.1 Setting Network Aera
This step is for setting both CSE-H55 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.

Setting of CSE-H55
CSE-H55 uses ezManager as it’s a configuration program. ezManager is for MS
Windows, and this is comfortable to use because it doesn’t need installation. First,
search your CSE-H55 via network. All the values of parameters are set the default
values in the factory. To apply it to your system, proper values should be set via
ezManager. Major parameters’default values are listed on below table. To implement
this simple test, keep these values without any changes.
