Nexus Web App
Remote control the A20-Nexus from anywhere in the world using the Nexus Web App, a browser-based remote control application
for the A20-Nexus that can be run on any computer, tablet, or smartphone. It duplicates virtually all of the functions available from
the A20-Nexus front panel. The integrated RTSA view is particularly useful for performing real time spectrum analysis over a wired
or wireless network. Export the RTSA data as .csv and .png files to keep a record of a location’s RF environment.
The app’s GUI is dynamically optimized for the screen size on which it’s being viewed, whether a computer, tablet or smartphone
screen.
Note:
To ensure the web app functions correctly, use the latest version of your preferred browser. Chrome and Safari are
recommended.
Note:
When using a Wi-Fi access point with the A20-Nexus, it is best practice to switch the Wi-Fi access point to 5.8 GHz so that
the Wi-Fi doesn’t interfere with the 2.4 GHz NexLink.
Accessing the Nexus Web App
1.
The web-enabled device being used must be on the same network as Nexus to access the web app. A VPN is required if
Nexus is outside of the local network.
2.
See
for information on how to configure and connect the Nexus to a network.
3.
Go to the Network menu.
4.
Make a note of the IP address shown in the Control IP Settings screen.
5.
Enter that IP address into a web-enabled device’s web browser.
More than one web-enabled device can be used to access the app allowing multiple users to simultaneously control the same
Nexus. For instance, one team member can be monitoring the RTSA, another crew member monitoring audio level, etc.
Tip:
When running multiple A20-Nexus receivers, open each one in its own separate browser tab.
For the purpose of this user guide, all web app screenshots are captured using an Apple MacBook Pro 15” computer.
