1 Overview
1.1 Overview
CSE-M73G lets the serial devices connect to the Internet. To communicate on the
Internet, devices should use TCP/IP protocol, so CSE-M73G processes the converting
serial data to TCP/IP.
CSE-M73G supports RS232, RS422, RS485 and 3.3V. The interfaces including the RJ45
connecter let users apply this module to their system easily.
1.2 Main Features
⚫Serial to Ethernet Module
⚫Pin-compatible design with CSE-M73 and CSE-M73A
⚫RJ45 connector embedded
⚫Multiple connection for multi-monitoring
⚫IPv4 / IPv6 dual-stack
⚫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
CSE-M73G is basically designed to be pin to pin compatible with CSE-M73 and CSE-
M73A, but there are differences according to MCU characteristics. Therefore, be
sure to run a compatibility test first when using the CSE-M73G as a replacement.

2 Installation and Test
2.1 Installation
Before testing the CSE-M73G, you should connect both serial and Ethernet port to
your PC. Please connect the Ethernet port to your PC directly or through a switching
hub.

2.1.1 Setting Network Aera
This step is for setting both CSE-M73G 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
Set the IP address to the Ethernet adapter of the PC connected to the product
as follows.
