INTRODUCTION
Congratulations on your purchase of this 802.11a/b/g/n PCIe Adapter.
This manual helps to get familiar with the Wireless PCIe Adapter. This manual
contains detailed instructions in operation of this product. Please keep this manual
for future reference.
With a Wireless LAN (IEEE 802.11g) mini PCI Adapter, a desktop or laptop
computer can communicate with another computer in a wireless way. Easy-to-use
utilities are bundled with Wireless mini-PCI Adapter for configuration, monitoring,
and diagnosis purposes.
Wireless PCIe Adapter can wirelessly transmit and receive data, minimizing the
need for wired connections, at a speed of up to fifty-four megabit per second.
Wireless PCIe Adapter provides users with an access to real-time information
anywhere in their organization. The mobility provides productivity and service,
which are not available under wired networks. The Wireless PCIe Adapter
configuration is easy to change from peer-to-peer networks, suitable for a small
number of users, to full infrastructure networks of thousands of users that allow
roaming around a broad area.
Overview of this User’s Guide
Introduction. Describes the Wireless PCIe Adapter and its features.
Software Installation. Tells how to setup the driver and the utility setting.
Technical Specifications. Lists the technical (general, physical and environmental)
specifications of the Wireless PCIe Adapter.

SOFTWARE INSTALLATION
This section will lead you to install the driver and utility of the Wireless PCIe
Adapter via Windows OS installation.
Windows 98se/ME/2000/XP Utility and Driver Installation
1. Insert the Wireless LAN mini PCI Adapter Driver & Utility CD-ROM into
computer’s CD-ROM Drive and it will automatically run a setup menu and
install the driver and the utility, for Win98se, please reboot the system to install
the driver to the system properly. In some specific setting on Windows system,
you may need to proceed the software manually, go to your Windows Start
menu and choose Run, type “D:\Utility\Setup.exe” in the dialog box (D:\ will
depend on where your CD-ROM drive is located) and click OK.
2. If you need to install the driver manually, refer each Windows OS to the
following CD-Rom directory path: D:\Drivers\<Windows OS>\SIS163U.INF.
Note: (D:\ will depends on where the CD-ROM drive is located and
<Windows OS> will depend on the Windows Operating System you are using).
3. The Install Shield Wizard screen will appear. Click “Next” to continue.
4. The installation program will help you to setup the Wireless Utility.
Be noted that the Windows XP have its own Wireless Utility; you can either
use the utility of Windows XP or the provided utility.
5. You will see the icon on the Windows task bar when you finish the installation.
When the icon in the toolbar represents in green color, it is properly connected
to the network and if it represents in red color, then it is not connected to the
network.

Wireless Utility Setting
With the Wireless PCIe Adapter utility, users can configure all the functions
provided by the Wireless Monitor Utility. Double-click the utility icon that appears
in the taskbar.
The Wireless Monitor Utility includes seven tabs: Status, Configuration, Advanced,
Profile, Network, Statistics and About.
Status
The Status screen shows you the status of the Wireless Adapter, it shows that where
the device is connected to, the Network mode, the Channel, the transmit rate and
the encryption mode.
There are two dialog boxes showing the data transmitted and the data received. The
two signal lines show the Signal Strength and the Link Quality of the device.

Configuration
The Configuration function helps you to configure the Network and the Security.
Network: the setting of the Network mode, the SSID and the Channels.
Network Mode:
If you want to connect with an Access Point, please set to “Infrastructure” mode. If
you have more stations and just want to set them as local network, please set the
mode to “Ad-Hoc” mode.
Network SSID:
The SSID differentiates one Wireless LAN group name from another; so all access
points and all devices attempting to connect to a specific Wireless LAN group
name must use the same SSID. A device will not be permitted to join the BSS
unless it can provide the unique SSID.
If the SSID parameter is “ANY”, it will detect the strongest signal of the wireless
station.
Channel:
It shows radio channel numbers that used for Wireless LAN networking.
The channel number can be set only under the Ad-Hoc operation mode. In Ad-Hoc
mode stations, each station must have the same channel numbers and SSID.
In Infrastructure mode, the Wireless mini-PCI Adapter will automatically detect the
channel number of the Access Point.
Security: the setting of the Network Encryption.
This function is used to protect wireless communication from eavesdropping. A
secondary function of encryption is to prevent unauthorized access to a wireless
network, and it can be achieved by using the Encryption function.
Encryption Mode:
There are two kinds of encryption mode, WEP encryption and WPA-PSK.
Click the Enable Encryption to activate the security of the mini-PCI Adapter.
WEP-Key: WEP (Wired Equivalent Privacy) relies on a secret key that is
shared between a mobile station and a base station (Access Point).
WEP-Passphrase: the Passphrase in the dialog box helps you to create a
group of WEP key in the Key Setting.
Authentication Mode:
Open System: with the same WEP key between the stations, the stations
don’t need to be authenticated, and this algorithm was set to default.
Shared Key: with the same WEP key between the stations in this
Authentication algorithm, this type will use packets with encryption by
transferring a challenge text which will be acknowledge by both side of the
stations. In order to choose which authentication algorithm will be used, you
must know which one the station supports this algorithm first.
5
It is recommended to select “Auto” if you are not familiar with the setting.
Default Key (Key 1 ~ Key 4):
You can type the key that you want to use from Key#1 to Key #4, and the key that
you type will be the encryption between the stations that you connected with.
Key Length, Key Format and WEP Key:
If you select 64bit in Hex format, you must type 10 values in the following range
(0~F, hexadecimal), or 64bit in ASCII format, you must type 5 values in the
following range (0~9, A~Z and a~z Alphanumeric).
If you select 128bit in Hex format, you must type 26 values (0~F, hexadecimal), or
128bit in ASCII format, you must type 13 values in the following range (0~9, A~Z
and a~z Alphanumeric).
Be sure that the mini-PCI Adapter and the wireless station were set in the same key.
Note: After all the settings are completed, click Apply to save the setting.
6
WPA-PSK: WPA-PSK (Wi-Fi Protected Access pre-shared key) is a simpler
version that does not support 802.1x and requires a separate RADIUS server for
mutual authentication.
Enter a Passphrase in the WPA-PSK dialog box. This passphrase must be the same
on each computer that is connected to the wireless network.
7
Advanced
The Advanced settings help you to control the Wireless Adapter to adjust with
wireless devices in certain environment.
Transmit Rate:
You can choose one of the transmission rates as follows, 54Mbps, 48Mbps,
36Mbps, 24Mbps, 18Mbps, 12Mbps, 11Mbps, 9Mbps, 6Mbps, 5.5Mbps, 2Mbps,
1Mbps, and Fully Automatic. The Fully Automatic will automatically detect the
suitable linking transfer rate and auto fall back when the signal is not too strong to
transmit data, it will auto fall back from 54Mbps to 1 Mbps.
Power Saving:
To set your Wireless Adapter as power saving mode, select “Off”, “Normal” or
“Maximum”.
Transmit Power:
By selecting the Transmit Power, you can select the Radio Frequency output power
from Minimum, 12.5%, 25%, 50%, 100% or Auto.
8
Preamble Type:
The usage of the preamble is to limit the packet size of the data to transmit. It is
recommended to choose the short preamble when the link quality is bad, it is to
prevent the wasting time of resending a long packet that is lost. The Default is Auto
which access short and long preamble.
Fragment Threshold:
Fragmentation Threshold is a way of transmitting the packets that will be
fragmented. Choose a setting within a range of 256 to 2432 bytes. It is
recommended to fragment the packet when the link quality is bad, it is to prevent
the wasting time of resending a long packet that is lost.
RTS/CTS Threshold:
The RTS/CTS Threshold is a station initiates the process by sending a RTS frame,
the other ends receives the RTS and responds with a CTS frame, the station must
receive a CTS frame before sending the data frame. This is to prevent the collisions
by each station. Choose a setting within a range of 256 to 2432 bytes. It is
recommended limiting a long packet to prevent each station waiting too long to
transmit a data.
