Quatech SDS User’s Manual 
Enabling Wi-Fi Device Servers 
Quatech’s Wi-Fi Device Servers need to have a wireless network 
connection established before they can be configured for use. To 
enable the wireless connection, you need to obtain the SDS’ IP 
address as outlined below. Once you have the IP address, you can 
configure the SDS for wireless communications via the Web interface.  
In Infrastructure mode, you can use your wireless SDS just as you 
would a wired SDS, but it will communicate via an access point on 
the 801.11b network rather than through an Ethernet cable. The SDS 
will scan all channels until it finds an AP, at which time the Link 
LED on the Ethernet port will glow green. 
The following briefly describes how to obtain the IP address of the SDS 
and to enable wireless communications. For greater detail, see Installing 
the device drivers on pag
e 16 and Setting network parameters on page 45. 
Step 
Procedure 
Description 
‰ 
Step 1 
Turn on the power to your computer system.  
‰ 
Step 2 
Insert the Quatech SDS installation CD-
ROM into your CD-ROM drive. 
If the CD-ROM does not launch 
automatically, select Start – Run from the 
Task bar, browse to the CD-ROM drive,  
and select the ThinQ.exe file. Click “OK” in 
the Run window to launch the 
installation. 
‰ 
Step 3 
From the Main Menu, select Install SDS. 
Click Next. 
 
‰ 
Step 4 
Connect the Ethernet port on your SDS 
either to the NIC port on your computer or 
to a switch/hub. 
Use a CAT5 or better Ethernet cable to 
attach the SDS. 
‰ 
Step 5 
Connect power to the SDS. When the SDS 
is ready, click the Next button to search for 
Serial Device Servers. 
When the SDS is ready, the Status, Power, 
and Link LEDs should glow. 
‰ 
Step 6 
When the search is finished, find your SDS 
and make note of its IP address.  
Press Cancel to abort the installation 
procedure. 
You will need this address for the network 
configuration. 
‰ 
Step 7 
Open your Web browser and type the IP 
address for the SDS in the Web browser’s 
URL (address) field. 
The Quatech Device Server Home page 
displays. 
‰ 
Step 8 
Click on Network in the selection bar. 
 
‰ 
Step 9 
Select Infrastructure as the Access Mode. 
 
‰ 
Step 10 
Configure the Device Server’s SSID to 
match the access point’s SSID. 
To communicate wirelessly, the AP and 
the SDS must both use the same SSID. If 
you don’t know the proper SSID, check 
with your system administrator. 
Note: In Ad hoc mode, the Link 
LED on the Ethernet port will 
glow green when your wireless 
SDS finds and communicates 
with another device. 
 
Note: Wi-Fi Device Servers link 
via an AP in Infrastructure 
mode; they connect directly to 
another device in Ad hoc mode.
