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.
CSE-M73A lets the serial devices connect to the Internet. To communicate on the Internet,
devices should use TCP/IP protocol, so CSE-M73A processes the converting serial data to
TCP/IP.
CSE-M73A supports RS422, RS485 and 3.3V as well as RS232. The interfaces including the
RJ45 connecter let users apply this module to their system easily.

Figure 1-6 Interface
1.5.1 RS232 Port (JP1 and JP2)
CSE-M73A has an RS232 port for serial device (300bps ~ 230,400bps). This port is
interfaced with JP1 and JP2. It supports RTS/CTS hardware flow control and pins which have
the same number of JP1 and JP2 are connected each other.

1.5.2 RS422 and RS485 port (JP4 and JP5)
CSE-M73A has a port for RS422 or RS485. This port is interfaced with JP4 and JP5. The
pins which have the same number of JP4 and JP5 are connected each other. When you
connect your device, remember that a pin should be connected with the one which has the
same polarity. Of course, an output pin (Transmit-TX or TXD) has to be connected to an
input pin (Receive-RX or RXD).

Since part of CSE-M73A network is composed of Ethernet, UTP cable may be connected.
It will automatically sense 10Mbits or 100Mbits Ethernet and connect itself. It also provides
auto MDI/MDIX function that can automatically sense 1:1 cable or cross over cable.
Each Ethernet device has its own unique hardware address. The hardware address of CSE-
M73A is set in the factory before being shipped to the market. (The hardware address is
also known as the MAC address)

1.5.5 ISP Jumper
You can change the operation mode of CSE-M73A to ISP or Serial Configuration mode
by using this jumper.

2 Installation and Test
2.1 Installation
Before testing the CSE-M73A, users should connect both serial and Ethernet port to a PC.
It is fine that the Ethernet connection includes network hubs.
Figure 2-1 connection between M73A and a PC
Procedures for the test are followed.
2.1.1 Setting Network Aera
This step is for setting both CSE-M73A 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.

⚫Setting of CSE-M73A
CSE-M73A uses ezManager as it’s a configuration program. ezManager is for MS
Windows, and it doesn’t need installation.
All environmental variables are set to the factory default values, so they must be
changed to suit the purpose of use in order to apply them to the actual system. The
following table shows the default values of the main environmental variables. For test
operation, please keep the CSE-M73A's IP address and all environment values as the
default settings below.
