Z15 - 5D Link Issue

[teecee]

So I have my Z15-5D linked and receiving basic control from my second TX (Futaba T8FG). I am using the Futaba R6208SB RX via Sbus. Roll, Tilt, Pan and Mode are all successfully mapped and working correctly but I just can't seem to get the Shut and Aux 1-3 mapped. Shut (values 606-969) and Aux 3 (values 453-622) are showing feedback in the 5D assistant software on SF switch. I can not seem to un map SF right now. I know it is Idle Up but I find the Futaba interface very frustrating to navigate. I would like to map SH to Shutter and SF to video roll etc.

Also, what is Aux 1? Mine says "reserved".
What is Aux 2? Mine says "downward" and "forward"

I am frustratingly close here...

And one more thing... Now when I take the whole rig to another room for flight test I can not seem to bind the RX to the TX. I made no changes. Weird. It took a while to bind the first time and now not at all. Bummer!

Got it working. It wouldn't bind because I had the "pilot" transmitter on at the same time. Duh...
