3. Connection to a Cable/DSL Router 
 
This is the most ideal situation in that it allows you to access your STARGATE via the 
Web Xpander from your home network as well as anywhere on the internet once you’ve 
configured both the Web Xpander and your router.  In most cases, the router will also act 
as a DHCP server and provide the initial network settings for the Web Xpander. 
 
 

Network Configuration 

 
Every device on a TCP/IP network must have a unique IP address.  IP addresses are 
always numeric and in the format xxx.xxx.xxx.xxx.  The default Web Xpander IP address 
is “192.168.0.5” (if no DHCP server was found).  Most home cable/dsl routers default to 
“192.168.0.1” for the router and dynamically assign addresses (using DHCP) to PCs 
starting from “192.168.0.100”. 
 
When you first power up the Web Xpander (and after either a power loss or by pressing 
the small reset button) it will attempt to retrieve its network settings using DHCP unless 
you have disabled this feature. 
 
DHCP stands for Dynamic Host Configuration Protocol.  The principle is that a device 
that knows nothing about its own network settings sends out a broadcast saying, in effect, 
tell me what to do. The DHCP server is listening for these broadcasts, and responds with 
information containing the settings that device should have.  Typically the information 
returned contains IP address, netmask, gateway and DNS settings.  Most home 
Cable/DSL routers support DHCP “out of the box.” 
 
After you’ve connected the Web Xpander and applied power to the STARGATE, run 
WinEVM on your PC.  After WinEVM starts, click the MegaController button.  A 
properly functioning MegaController dialog indicates that the data cables are correctly 
installed between the PC and the Web Xpander, and between the Web Xpander and the 
controller.
