Configuring the SDS using a Web interface 
 
Quatech SDS User’s Manual 
Configuring the SDS using the Web interface 
This section explains how to configure an SDS using a standard Web 
browser so that it can communicate over a network with a serial 
device.  
After the installation program included on the SDS CD-ROM is 
finished, the Device Server will be ready for use as configured. If you 
wish to make changes to the configuration at a future time, it is a 
simple matter of entering the IP address of the Device Server into the 
address bar of your computer’s Web browser.  
Note: Wi-Fi units must have 
their parameters configured 
before they can communicate 
wirelessly. See page 6 for Wi-Fi 
information and page 14 for 
configuration information. 
Quatech recommends the use of Microsoft’s Internet Explorer for 
accessing the Web browser-based configuration utilities built into our 
Device Servers. Other browsers can be used but be aware that we 
have not tested the many alternative browsers available, so some 
graphics and page formatting could be misaligned. 
Note: We have eliminated the 
need to use console ports, DOS 
shell commands, Telnet and 
other complicated methods of 
configuration. Just enter the IP 
address after the HTTP:// 
prefix in your Web browser’s 
Address bar, click Go, and you 
are ready to reconfigure the 
Device Server remotely! 
 
The SDS stores its configuration in nonvolatile memory (Flash), 
which is retained even when the unit is turned off.  
Once you have installed the drivers on your computer and established 
an Ethernet connection with the SDS, you can maintain and configure 
the SDS using a Web interface.  
Using a Web interface, you can:  
¾ 
Configure the network settings (static vs. DHCP; if static, you can 
set the IP address, Gateway address, and Address mask) 
¾ 
View and set the serial port parameters (set per serial device 
application; setup lets you set data rate multiplier, performance 
mode, heartbeat timer, operating mode and operating mode settings) 
¾ 
Perform diagnostic tests (Ping test, view port status list) 
¾ 
Perform administrative functions (view, add, or remove users, 
give the SDS a descriptive name, upgrade software, and perform 
a remote reset)  
¾ 
Contact Quatech corporate headquarters, sales, and technical 
support 
Follow these steps to manage your SDS using a Web interface.
