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-H25 lets the serial devices connect to the Internet. To communicate on the Internet,
devices should use TCP/IP protocol, so CSE-H25 processes the converting serial data to
TCP/IP.

1.5 Interfaces
1.5.1 Serial Interface
CSE-H25 has an RS232 port for user serial device (300bps ~ 230,400bps). CSE-H25
converts serial data from user device to TCP/IP and transmits to Ethernet port.

1.5.2 Ethernet Interface
Since part of CSE-H25 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-
H25 is set in the factory before being shipped to the market. (The hardware address is also
known as the MAC address)
Fig 1-6 the Ethernet interface
1.5.3 Power
DC5V is used for the power. The specifications of the power jack are as the following:

2 Installation and Test
2.1 Installation
Before testing H25, users should connect both serial and Ethernet port to a PC. It will be
no problem that the Ethernet connection includes network hubs.
Fig 2-1 connection between H25 and a PC
Procedures for the test are followed.
2.1.1 Setting Network Aera
This step is for setting both CSE-H25 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.
Fig 2-2 adding / changing the IP address of users’PC

CSE-H25 User’s Manual Ver. 1.4
Sollae Systems Co., Ltd. - 11 - http://www.sollae.co.kr
Setting of CSE-H25
CSE-H25 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-H25 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.

3.3 Assigning an IP address automatically
3.3.1 Obtain an IP automatically (DHCP)
In the network environment composing DHCP server, settings related to CSE-H25’s IP
address, subnet mask, gateway, and name servers can be automatically designated using
DHCP protocol. In order to do so, you must check [Obtain an IP Automatically (DHCP)]
category on the ezManager. In this case, you can set the address of DNS server manually
or automatically.
Fig 3-7 Obtain an IP automatically via DHCP
Procedures
①Choose [Network] tab
②Check the [Obtain an IP automatically (DHCP)] category
③Store the setting with [Write] button
④Check if an IP address has been assigned from status window with [Status] button

CSE-H25 User’s Manual Ver. 1.4
Sollae Systems Co., Ltd. - 19 - http://www.sollae.co.kr
3.3.2 Obtain an IP automatically (PPPoE)
PPPoE is used in most ADSL and VDSL networks. To use PPPoE function, PPPoE function
should be enabled and PPPoE ID and PPPoE password should be configured. The local IP
address of CSE-H25 is assigned automatically in PPPoE environment. In this case, you can
set the address of DNS server manually or automatically.
Fig 3-8 obtain an IP automatically via PPPoE
Procedures
①Choose [Network] tab
②Check the [Obtain an IP automatically (PPPoE)] category
③Set correct values of [PPPoE ID] and [PPPoE Password]
④Store the setting with [Write] button
⑤Check if an IP address has been assigned from status window with [Status] button
 Some ADSL or VDSL environments use DHCP based on the modem type. Please contact
your internet service provider (ISP) for further information.
