Introduced in 2007, Nautel’s Advanced User Interface (AUI) provides local and remote monitoring and control for NV, GV, NX, NVLT, and VS transmitters.
In 2020 Nautel will replace the Flash-based AUI with an 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 from your transmitter, so there is no “app” to install or maintain on your remote devices.
See below for update on NEW Flash AUI Access App. New version released 23rd Oct 2020
The new AUI takes advantage of the latest browser technology that enables us to not only retain the rich graphics of the original AUI but to 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.
The new Dashboard icons provide a cleaner interface (Hovertips explain what they are while you are getting to know them).
Diving into the user interface a bit deeper, here is the Presets page. Everything is usable even when operated on smaller touchscreen devices like a phone.
The upcoming stage will be beta testing on each transmitter series: BETA SIGN-UP PAGE

Flash AUI: Nautel Legacy AUI Access App
As winter approaches in the Northern Hemisphere, access to higher altitude transmitter sites is already making onsite software updates challenging. So Nautel has developed a Windows and macOS desktop app which eliminates the dependence on your browsers to access the Flash AUI and ensures uninterrupted access to your transmitters without any changes. This interim solution will function throughout 2021 so you can choose when you want to migrate to the new AUI.
Flash AUI: Browser Support
All major browsers will support Flash Player until January 1st 2021. In the meanwhile here is what to expect from each:
- Warning shown when browser is launched (If you have previously blocked Flash, go to Settings | Privacy & Security | Site Settings and change the Flash settings. Detailed Steps.)
- Prompt to allow Flash to run
- Flash is supported until end of 2020
- The new Edge (2020) is built on Chromium (same as Google Chrome)
- Dialog prompts to allow Flash to run
- You are prompted to install Flash plugin – complete that process to run AUI
- Flash is supported until the end of 2020.
- Prompt to allow Flash to run
- Supports Flash until end of 2020
- Standard (consumer) Firefox version will not run Flash after the end of 2019
- To run Firefox after 2019 use Firefox ESR (Extended Support Release)
- Firefox ESR supports Flash until the end of 2020
Microsoft Internet Explorer
- Requires no special setup to run
- Supports Flash until the end of 2020
Touch Screen AUI on Transmitters
The touch screen AUI on the NV, GV, and NX Series transmitters will continue to operate unchanged. When you upgrade to the HTML5 AUI, the touch screen interface will also be upgraded.
Some smartphones and tablets can be configured for running Flash using special browsers, but it has become harder with vendors such as Apple and Samsung working hard to prevent it.

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.
