Page 5: Overview
The serial communication is quite simple to implement but has weaknesses like short distance and hard maintenance. CSE-H55N lets the serial devices connect to the Internet. To communicate on the Internet, devices should use TCP/IP protocol, so CSE-H55N processes the converting serial data to TCP/IP. -

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-H55N to ISP or Serial Configuration mode with this switch. And it is used for factory reset. -
Page 16: Installation And Test
Before testing CSE-H55N, users should connect both serial and Ethernet port to a PC. To connect the RS232 port of your PC and CSE-H55N via serial, you need a RS232 to RS422/RS485 converter. It will be no problem that the Ethernet connection includes network hubs. -
Page 17: Setting Network Aera
CSE-H55N User’s Manual Ver. 1.2 2.1.1 Setting Network Area This step is for setting both CSE-H55N 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. - Page 18 Windows, and this is comfortable to use because it doesn’t need installation. First, search your CSE-H55N 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.

Page 28: Communication Modes
Communication Modes 5.1 TCP Server In this mode, CSE-H55N listens to a TCP connection request from remote hosts. Once a host tries connecting to CSE-H55N, it accepts a connection. After the connection is established, CSE-H55N converts the raw data from the serial port to TCP/IP data and sends it to the network and vice versa. - Page 29 5.1.2 Examples A situation that [Event Byte] is set to 0.

Page 32: Tcp Server
In this mode, CSE-H55N sends request segments to a TCP server with information of [Peer Address] and [Peer Port]. Once a host is listening, the connection will be established. After then, CSE-H55N converts the raw data from the serial port to TCP/IP data and sends them to the network and vice versa. - Page 33 Figure 5-4 time chart Points States Power is not supplied yet. ① CSE-H55N sends a connection request segment right after it boots up Processes of TCP connection ② The connection is established.
