Problem with Jumper T8SG, Fs-a8s and Xpilot AX601

Hi, as in object I own the three devices in question. My problem is the following.
When I bind the t8sg with the fs-a8s everything seems to work correctly, but when I then connect the fs-a8s to the xpilot and try to configure it (it requires some stick operations) it doesn't seem to receive any commands. If someone uses the same transmitter / receiver pair could they kindly send me their communication parameters or give me some indication?
Thank you

Today after making several attempts I solved my problem.
Everything arose from the fact that the fs-a8s receiver can work both in sbus and ibus mode while the "volantex xpilot ax601 "only in sbus.
The real problem is that in the flysky fs-a8s receiver manual it is nowhere indicated how to switch from ibus mode to sbus and vice versa.
Basically, once the receiver has been linked with the transmitter, it is necessary to hold down the binding button for two seconds (while the red light of the receiver is fixed) and you will see a double flash to indicate that the mode has been changed.
