Old Turnigy 9X V2 which was AFDHS and new recievers

Hey!

Need your help with old 9X.

Example reciever:
https://hobbyking.com/en_us/turnigy-ia6c-ppm-sbus-receiver.html
there is info "works with [....] or Turnigy AFDHS 9x transmitters."
9X has two version now. The OLD one which is AFDHS ( without 2A) and new one with "2A".
Question is: what author of description has in mind when writing description.
I have old 9X V2(discontinued) and I need new reciever able to use iBUS/SBUS for Omnibus F4 FC
Will it work?
In discussion under product, someone says it won't someone: it will.

Maybe there is diffrent products I can use with my FC?

Regards,

Piotrek
