Document status: 2021-11-22
==============================================================

This document advises about the firmware update procedure.  The process is similar to 
updating the multiverter's firmware itself.

Firmware update
===============
1. Switch the flexiverter OFF.

2. Connect the flexiverter via USB to your PC (anything from Windows 7 on should work). 

3. Switch the flexiverter ON and wait about 10 seconds until USB has been detected

4. Run "FLX-DANTE-Updater.bat" and confirm with "U". The update process takes about 
   1 minute. Check the screen output for any error messages. If an error occured
   try again or refer to the "Troubleshooting" section below.
   
5. Power cycle the device
   
6. *** NOTE: Only required when *.dnt in "firmware" directory is newer than previous version ***
   *** If the file is the same, you are finished now ***
   
   Update the Dante module itself over the network, using Dante Controller  
   https://www.audinate.com/products/software/dante-controller
   
6. Power cycle the device again
   
7. Check if the update was successful: Hold "MODE" button while switching on the device.
   - The number of pink LEDs are the major version number X
   - The number of orange LEDs are the minor version number Y
   - The number of green LEDs show the hardware version Z.
   Note that Y or Z may be zero (no LEDs).
   Press MODE repeatedly until normal operation.
   - Check in Dante Controller for FLX-* devices.
   
   
Troubleshooting
---------------
1. Upgrade the Firmware manually:
   - Open a command prompt and navigate to the directory where README.TXT is located.
     Run the following command:
    "win\fwloader -f firmware\flx_dante.rpd -m 1 -e 16"
   - Update Dante as described above
