Need help binding Turnigy 9x (er9x) with receiver

[dogiaokhanhlinh]

Hello, all.
I got a problem binding Turnigy 9x (re-flushed to er9x) with this receiver
I am a new to a hobby, and when I got this transmitter and this receiver, I was able to bind it with "stock" (original) Turnigy 9x software. Now, After I reprogrammed it to er9x, (and successfully bound it to a receiver which came with it), I cannot bind it to this one.
I am using same PPM protocol as with original receiver with NEG set as a polarity of impulses, but no luck. Help, please!!!

What model of receiver are you trying to bind to? Turnigy/Flysky use two protocols, AFHDS and AFHDS2 or 2A, not all receivers are compatible with both protocols.

So you bound to the original Rx but can't bind to a 2nd Rx?

If so, I agree with @FDS, you need to be sure the 2nd Rx is the same protocol as the original AFHDS or AFSDS2. My guess, the module you have is the Tx is an older one, AFHDS only, and not compatible with the newer AFHDS2 protocol.
