GDS3705 User Manual
Version 1.0.0.20
Power GDS3705 using PoE
•Cut into the plastic sheath of your Ethernet cable, then Unwind and pair as shown below.
Use the TIA/EIA 568-B standard, which define pin-outs for using Unshielded Twisted Pair cable and
RJ-45 connectors for Ethernet connectivity.
Figure 6: Connection Example
•Connect each wire of the cable to its associate on the Back Cover of the GDS3705 to power the
unit using PoE.
Power GDS3705 using PSU
•To power the unit using PSU, use a multimeter to detect the polarity of your Power Supply, then
connect GND to negative pole and 12V to positive pole of the PSU.
Note: If the user doesn’t have PoE switch, there is no need to connect the Blue and Brown wires to the
GDS3705 since these wires are used to power the unit via Ethernet.

GETTING TO KNOW GDS3705
The GDS3705 has an embedded Web server to respond to HTTP/HTTPS GET/POST requests. Embedded
HTML pages allow users to configure the GDS3705 through all available Web browsers in the internet.
Connecting GDS3705 to Network with DHCP Server
The GDS3705 by default has a DHCP client enabled, it will automatically get IP address from DHCP server.
Windows Platform
Two ways exist for Windows users to get access to the GDS3705:
UPnP
By default, the GDS3705 has the UPnP feature turned ON. For customers using Windows network with
UPnP turned on (most SOHO routers support UPnP), it is very easy to access the GDS3705:
1. Find the “Network” icon on the windows Desktop.
2. Click the icon to get into the “Network”, the GDS3705s will list as “Other Devices” shown like below.
Refresh the pages if nothing displayed. Otherwise, the UPnP may not be active in the network.
Figure 8: Detecting GDS3705 via UPnP
3. Click on the displayed icon of related GDS3705, the default browser (e.g.: Internet Explorer, Firefox
or Chrome) will open and connect directly to the login webpage.
