Redundancy problem with R9MX
Has anyone else had success with getting the R9 to act as a redundant link with an R9Pro?I
've tried doing this just recently with the receivers I got in the combo pack (R8 pro and R9 MX), with the sbus out from the R9 going to the sbus in on the R8.
I registered and bound the R8 as RX1, and setup the aircraft. Then plugged in the R9, registered it, bound it to RX1 as well (as per FRSky manual), and everything seems OK - green lights on both RX's and two signal icons on the X20S. I can discover sensors, and both RX's telemetry outputs come up all fine on the TX.
I am not sure how to check the R9 is doing what it should though - if I turn off the 2.4 output from the TX, I get no control, but telemetry still comes through.
dont think there is a problem but i would update to the 1.10 now released fully.
the way i would test it is put foil over the antenna and move away approx 100m should get it to fault out.
It's a problem in the X20 / Ethos manual (p61). They say to bind the R9 almost in an additive way to your original RX1, binding it over the top. RCGroups guys said no, bind it as RX2 - I tried that and it all works. I am now able to turn off the 2.4 RF section and retain control on 900mhz. Phew! I've got a biggie to maiden this weekend and wanted to make sure the RF link was as strong as I could get it.
ah of course yes 😉
