2 Installation and Test
2.1 Background knowledge of WLAN
CSW-H85F supports IEEE802.11b/g. IEEE 802.11 is also called Wi-Fi and has two network
topologies and those are Infrastructure and Ad-hoc mode. CSW-H85F also supports WEP,
WPA-PSK and WPA2-PSK for security.
2.1.1 Topology
Infrastructure mode
In this mode, every wireless LAN station communicates through an Access Point (AP)
so that all stations can be connected to Ethernet, because AP is able to interface
witch both wireless LAN and wired LAN (Ethernet).
Figure 2-1 infrastructure mode

CSW-H85F User’s Manual Ver. 1.0
Sollae Systems Co., Ltd.
- 15 -
http://www.ezTCP.com
Ad-hoc mode
Wireless LAN stations communicate each other without an AP in this mode. Therefore,
you can easily make this network. It is suitable for the situation when there is no
wired LAN requirement on a small-scale network. Usually, it is called peer-to-peer
mode.
Figure 2-2 Ad-hoc mode
2.1.2 Key terms
SSID(Service Set Identifier)
It is a name to identify the particular wireless LAN. So every single station should
have the same SSID to communicate in the network. In the case of infrastructure
mode, you have to set the same SSID with the AP to CSW-H85F. Otherwise, it won’t
communicate at all. The maximum length of this parameter is 31 bytes and the
default is “sollae”.
Channel
Wireless LAN stations communicate through the ISM (Industrial, Scientific, and
Medical) band which has the range of frequencies around 2.4GHz. IEEE 802.11
specification divides this band into 14 channels every 5MHz. If you install more than
one wireless network in the same area, the channels should be apart more than 4
channels to avoid interferences.

http://www.ezTCP.com
2.1.3 Authentication and Security
Authentication
A wireless LAN station should get authentication from the AP in the infrastructure
network. There are two methods for the authentication, Open system and the Shared
key.
WEP (Wired Equivalent Privacy)
The WEP is a secure protocol for wireless LAN. You need to set 64 bit or 128 bit key.
You can use both hexadecimal and ASCII code for this.
WPA (Wi-Fi Protected Access)
WPA is a security standard for users of devices equipped with Wi-Fi wireless
connection. It is an improvement on and is expected to replace the original Wi-Fi
security standard, Wired Equivalent Privacy (WEP). There are two modes about the
user authentication in WPA security. One is Enterprise which has an authentication
server and the other is PSK (Pre-Shared Key) which doesn’t have any servers. CSW-
H85F supports WPA-PSK.
WPA2
To final security of Wireless LAN, IEEE 802.11i which is a standard about Wireless LAN
has suggested the Counter Mode with Cipher Block Changing Message
Authentication Code Protocol (CCMP) for replacing the TKIP. CCMP uses Advanced
Encryption Standard (AES). WPA 2 adopts AES. WPA 2 has also both Enterprise and
PSK mode. CSW-H85F supports WPA 2-PSK.
 CSW-H85F supports WEP, WPA-PSK and WPA2-PSK

2.2 Installation
The following instruction is written based on use of evaluation board for CSW-H85F.
Before testing CSW-H85F, connect the serial port to your PC. And then, make wireless
LAN link between the PC and CSW-H85F using an AP or wireless LAN adaptor.
Figure 2-3 WLAN and RS232 connection using a laptop
2.2.1 Making Wireless LAN link
Wireless LAN link is not automatically established when you connect the AP or wireless
LAN adapter to your PC. Wireless LAN parameters should be configured on CSW-H85F.
Follow the steps below if you are a beginner.
Supplying Power
Supply power to the board.
Change the mode to [Serial Configuration mode]
Connect and disconnect the ISP# pin to GND between 20ms and 1 sec.
Reading environmental parameters
Run ezManager and open the COM port. And then, press the [Read] button.
Figure 2-4 reading environmental parameters
 You can download the latest version of ezManager on [Download] >> [Utility] >>
[ezManager] introduction pages of our website.

http://www.ezTCP.com
Configuring Wireless LAN Parameters
Move to the [Wireless LAN] tab, set the same SSID and security options to the AP. If
you want to know how to set or figure the AP’s value out, please ask the
manufacturer.
Figure 2-5 an example for setting WLAN parameters
 If you want to build up Ad-hoc network, choose [Ad-hoc] in [WLAN Topology] tab
and set a value in [SSID] tab. Search the wireless network on your PC and try
connecting your PC to the network.

2.2.2 Setting Network Area
These steps are for setting both CSW-H85F and your PC to be located in the same
network. Only if they are in the same network, the TCP connection between them can be
established.
Setting 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
see the properties of [Internet Protocol (TCP/IP)]. Here, press the [Advanced] button
for adding an IP Address like the figure below.
