Switch to Nautel’s AUI App Today! Article and Software here.


Introduced in 2007, Nautel’s Advanced User Interface (AUI) provides local and remote monitoring and control for NV, GV, NX, NVLT, and VS transmitters.

Nautel’s engineering team is in the advanced stages of replacing the legacy (Flash) AUI with the HTML5 version. The new version not only takes advantage of the latest browser capabilities and smaller size, but it works across desktop, tablet, and smartphone browsers. The new AUI, like the original, runs right from your transmitter, so there is nothing to install or maintain on your remote devices. This major software release will be provided for free.

In the meanwhile, Nautel is pleased to provide the Legacy AUI Access App, a desktop app for Microsoft Windows and Apple macOS, that enables secure access to the current AUI. See below for update on NEW Legacy AUI Access App v1.02, released 23rd Oct 2020


VS300 AUI Dashboard

AUI Dashboard – VS300

Using the most recent developments in HTML5 we are able to both retain the rich graphics of the original AUI and extend it in ways that were never possible in Flash. AUI will be much smaller so it starts faster and work better on limited bandwidth connections.

AUI Dashboard Icons

The new Dashboard icons provide a cleaner interface and “hovertips” explain what they are as you get to know them.

AUI Reports page – VS300

New to the AUI is the Reports page that lets you download CSV files of Event history, Active Preset settings, Meters, and Settings to your local hard drive.

We are currently in the beta testing phase for the VS Series, and the others will follow. If you are interested in being part of the tests, and have a transmitter you can spare to do the testing on, sign up here: BETA SIGN-UP PAGE

Nautel Legacy AUI Access App

Legacy AUI Access Launcher - multiple transmitters

Nautel is pleased to provide our stand-alone Windows and macOS desktop app, enabling direct access to your legacy AUI without a browser. The app also lets you can choose when you want to migrate to the new AUI once it is released.

Legacy AUI Access App v1.02: zero install: extract and run.

Linux: User tests indicate that the AUI App seems to run under Wine. However, as this may require distro-specific adjustments to run (such as font installation), this use is not supported, so please no support calls.



Adobe Flash Support

Adobe has now officially ended Flash support so we recommend that customers switch to the new Legacy AUI Access App, as the secure way to connect to your transmitter’s AUI. Note: the app requires transmitter software released in February 2016 or later, as these releases include updates required by changes in Adobe’s Flash technology at that time.

All major browsers have ended support for the Flash Player plugin, but will continue to run a previously installed Flash Player plugin with warnings until you either remove Flash or update your browser version. Microsoft Windows will eventually prevent the Flash Player plugin from running.

Adobe Flash Player removal – uninstall steps provided by Adobe:

There are some 3rd party apps or special browsers that may run the legacy AUI, but the only supported solution is the Nautel Legacy AUI Access app.



AUI Connectivity & Security

The AUI is a monolithic Flash app that is about 9 MB in size, so for low bandwidth connections this may take some time to download to your computer (Enough time to go make coffee as one engineer at NAB told us!). The good news is that once downloaded the only flow through the connection is real-time data from your transmitter. The following tips focus on transmitter connectivity and security.

  • Firewall: Protect your transmitter site network with a firewall, with incoming ports closed. The speed at which devices on an unprotected network connected to the Internet can be infected by viruses or automated hack attempts is breathtakingly fast.
  • VPN: The most secure way to connect remotely to your transmitter is via a VPN. Virtual Private Networks create an encrypted channel from your remote computer to your transmitter. It requires that a VPN client is installed at the site, typically on a site-based computer. VPN support is common these days, but involving an IT professional will save time and headaches.
  • Port Forwarding: While closing your incoming ports on your firewall is a standard security practice, opening specific outbound port(s) will enable you to access your transmitter without a VPN. It requires configuring the firewall router at your site, which gets trickier with multiple transmitters. As with VPN, involving an experienced IT person will save time and headaches if you aren’t familiar with this technology.
  • Host Watch Dog: If you have ever lost AUI or SNMP connectivity to your transmitter, it is possible your Host Watch Dog setting is incorrect: set it to “ON”. The Host Watch Dog monitors the internal transmitter systems and does a reset when necessary.
  • Passwords: CHANGE THE DEFAULT PASSWORDS FOR AUI LOGIN AND SNMP WRITE. Disable SNMP if you do not use it.
