Anyone with experience for FRSKY TFR8SB Mode B?

[ryanwhoo]

Hoping someone with experience can shed some light on how to set to mode B on this rx.

I've tried following instructions in the manual but can't get it to work, especially confused with the part where I'm supposed to connect sbus and rssi with cable provided (do i connect them together?)

Really appreciate if i can get some help.

Thanks!
