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.
To overcome those weaknesses, we offer “Serial Networking Solution” which allows the
serial devices to transmit/receive data over unlimited distance. CSE-H55N2 is one of “serial
networking” devices which lets the serial devices to connect to the Internet by converting
serial data to TCP/IP packet, and vice versa.
CSE-H55N2 is an upgrade version of CSE-H55N that has been designed to improve
stability against noise and electrical damage on RS422/485 line. There is no change in its
software
1.2 Features
IPv4 / IPv6 dual stack
Stateless / Stateful (DHCPv6) address auto-configuration
RS422/RS485 (Terminal Block)
Industrial temperature range (-40℃ ~ +85℃)
Variety of monitoring status (ezManager, TELNET)
Security Protocols SSL3.0/TLS1.0

1.6 Interfaces
1.6.1 Serial Interface
CSE-H55N2 has a serial port for user serial device (1,200bps ~ 230,400bps). This port is
interfaced with 6-pin terminal block and each pin should be fixed by a flat-head screwdriver
driver.

1.6.2 Ethernet Interface
Since part of CSE-H55N2 network is composed of Ethernet, UTP cable may be connected.
It will automatically sense 10Mbits or 100Mbits Ethernet and connect itself to network. It
also provides auto MDI/MDIX function that can automatically sense 1:1 cable or cross over
cable.

1.7.1 Function button
There is a switch, which is named function switch (or button) located on the side of the
product. You can change the operation mode of CSE-H55N2 to ISP or Serial Configuration
mode with this switch. And it is used for factory reset.

2 Installation and Test
2.1 Installation
Before testing CSE-H55N2, users should connect both serial and Ethernet port to a PC. To
connect the RS232 port of your PC and CSE-H55N2 via serial, you need a RS232 to
RS422/RS485 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.

2.1.1 Setting Network Area
This step is for setting both CSE-H55N2 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-H55N2
CSE-H55N2 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-H55N2 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.
