Flex USB port to Ciro Mazzoni ATU controller

I can not get the ATU controller to work in either full or semi auto mode . In manual it will select and tune. I am using the cable they sell for the Flex.

It sees the cable but doesn't appear to output frequency change as I tune the radio.

Settings are Cat, TX antenna, Ant2, Auto Report Enabled, Speed :9600 Bits 8 Parity none , stop bits 1

Flow control none.

Missing something ?

Thanks for any help

    Have you tried using "Specific Slice" vs. "TX Antenna"?

    Struggling with the same problem myself. Ticket in to Ciro. Already verified ATU2 firmware is on 4.06 which is required due to a flex cat change (per Ciro)
