Unpack the analyzer and look for the 15Vdc power adapter, cable kit, and CD. Look in the CD contents for the Avcom GUI vX.X installation executable. Install the GUI. Plug in the power adapter to the mains and the analyzer. If there is a power switch on your analyzer turn it on. Find the red ethernet crossover cable included with the analyzer and plug it from the analyzer directly into your computer. If you are using a router connect your own straight ethernet cable from the router to the analyzer. Install and run the Avcom GUI. In the GUI select Configure/Ethernet Connection. Select Scan for Devices and give it time to find your analyzer. If the Scan tool cannot find your analyzer you may need to use the direct crossover cable from the analyzer to the computer to find and configure the ethernet parameters. Once the Scan tool finds the analyzer you can Change the IP address to one that is valid for your network. Close the Scan window to return to the Configure Ethernet window. The factory default TCP port number is 26482. If this has been changed and you do not know what the existing port number is then select Query and Import Current Settings to get the current port number. Now that you have configured the analyzer’s ethernet parameters you are ready to configure the GUI to address the analyzer properly. Go to Configure/Spectrum Analyzer List and use the new(valid) IP address and TCP port number to Add a new item to the Spectrum Analyzer List.
