I have acquired a Ciro Baby Loop with the RS232 Module installed. The ATU 2.0 is running firmware version 3.14 and I want to update it to 3.22 so I have full auto control with my Kenwood TS590SG.
I have a problem that when I follow the instructions for the firmware update nothing happens. The ATU 2.0 detects a media device, shows board and firmware version then continues to the last used frequency.
Are there any special requirements when it comes to USB flash drive? Does it need to be a particular size or lower than a particular size? Does it need to be formatted in a particular way?
