1 Overview

1.1 Overview

Most of industrial devices support standard serial communications in which the sender

transmits the stream of bits to the receiver in order. Although serial communication is

known for its simplicity, its limitations are on the short communication distance and the

requirement of frequent maintenance, which prevent it from being popularly used in

modern computing environment.

By providing Internet connection to serial communication devices, CSE-M53N enables

them to overcome these limitations. Specifically, CSE-M53N, which has TCP/IP stack and

serial communication capability, converts serial data to TCP/IP data, and vice versa.

1.2 Main Features

⚫ Very compact module type: 20mm x 24mm

⚫ Multiple connection for multi-monitoring

⚫ IPv4 / IPv6 dual stack

⚫ Stateless / Stateful (DHCPv6) address autoconfiguration

⚫ High speed UART(Up to 921.6Kbps - 230.4Kbps when using Xon / Xoff or RS422 /

RS485)

⚫ 1 x UART, available on RS232/RS422/RS485 extension

⚫ Industrial temperature range (-40℃ ~ +85℃)

⚫ Security options (SSL/TLS, IP filtering, Password)

⚫ Separator settings for packet fragmentation



Multiple connection is supported in firmware version 2.3A or later.

2 Installation and Test

2.1 IPv6 address

With online devices increasing such as smartphones throughout the world, the number of

available IP addresses has continued to dwindle at an ever faster rate. This urgent problem

on lack of Ipv4 addresses finally led to the development of an advanced version, IPv6,

which has become a key word to effectively settle the matter.

IPv6 has a lot of merits on addressing capability, packet handling process and security,

however the devices or software for Ipv4 are not allowed on IPv6 network due to the

different addressing protocol structure. For this, CSE-M53N was developed to be available

on both networks by supporting dual stack.

2.2 Installation

Before testing CSE-M53N, users should connect both serial and Ethernet port to a PC. It

will be no problem that the Ethernet connection includes network hubs. In this document,

whole processes are written assume that using it with evaluation board.

Figure 2-1 connection between CSE-M53N and a PC

Procedures for the test are followed.

2.2.1 Setting Network Aera

This step is for setting both CSE-M53N 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.
