In this video of the Crown Comtech D-Series video manual series, we’re going to walk you through how to update your amplifier’s firmware using the AVX Manager software. In this example, we’ll be showing a BSS Omni device. This process is the same for any device that can connect with and use the AVX Manager software. 
In AVX Manager, devices that are in the same network as your computer will be automatically discovered and displayed in the table. The table will show the device name, manufacturer, family, and model. 
IP address can be edited by clicking this gear icon when hovering over the IP Address field. Last is the unit’s serial number and current firmware version. Hovering over the icon between the firmware version and update button will show you the latest available version to install. 
Clicking this icon, you’ll be presented with a new window asking to confirm the download and update of the firmware. Click yes to begin the firmware update. 
Firmware updates access a cloud server to update, and the files can be quite large, so it’s best to update device firmware on a fast and stable internet connection. 
Once the update has begun, the status of the device will show as “Started”, before showing as “Transferring”, and finally “Updating”.
Near the end of the update process, the device’s LEDs may go black, and the fans may ramp up high. This is normal, and the device will reboot on its own.  
At the same time, AVX Manager will show the device as offline until it’s fully rebooted. Once fully booted, the device will show as “Running” once again.
