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-M53G enables
them to overcome these limitations. Specifically, CSE-M53G, which has TCP/IP stack
and serial communication capability, converts serial data to TCP/IP data, and vice
versa.
1.2 Main Features
⚫Serial to Ethernet Module
⚫Super-compact module type: 20mm x 24mm
⚫Pin-compatible design with CSE-M53 and CSE-M53N
⚫IPv4 / IPv6 dual-stack
⚫High-speed UART(Up to 921.6Kbps, under certain conditions)
⚫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
 There are differences among CSE-M53, CSE-M53N, and CSE-M53G due to MCU
functions, despite the Pin-compatible design. Therefore, be sure to test the
compatibility when using CSE-M53G as an alternative.

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-M53G was developed
to be available on both networks by supporting dual stack.
2.2 Installation
Before testing CSE-M53G, 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-M53G and a PC
Procedures for the test are followed.

2.2.1 Setting Network Aera
This step is for setting both CSE-M53G 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-M53G
CSE-M53G 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-M53G 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.
