RX4R binding issue

Before I bind my RX4R to my 9x lite, do I need to update the firmware on it? Firmware on the 9x lite is updated thanks to FrSky booth at Flightfest.

If you are using Access firmware that doesn’t support D8 or D16, you will need Access firmware in the receiver module as well.
I think the very latest version did allow you to bind to D16 without needing to upgrade. Try it. If it doesn’t work then update the firmware on the RX.
