Frsky R9M lite

hi i was thinking to add frsky r9m lite to my devo 10, any ideas how to connect all the 8 pins on r9m lite to devo 10?

Picture of the X-Lite transmitter bay pinout . Couldn't find a picture of the module with pinout. The "first" five pins are the same pinout as the JR connector on the T8+. I like the picture because "first" could be either end.

Three connections are needed to the trainer port on the Devo10.
- trainer port tip to R9M PXX pin (PXX_OUT in picture)
- trainer port ring to R9M S.Port pin
- trainer port sleeve to R9M GND pin

The R9M Lite manual doesn't list max input voltage and don't know if the X-Lite pin labeled 6V is regulated or not. The power is up to you

so it only take 4 pin to connect to r9m lite. is it going to disable my voice output?

Correct. In the devo10 the same uart is used for both serial output and voice. Voice is disabled when a serial protocol is in use.

how about binding procedure. does it have fixed id?

Yes, zero to 63. There's more information in the user manual in the PXX protocol section.

i think there's a bug on the latest firmware for devo 10. i just upgraded tx firmware to the latest one. i've seen the new protocol but i haven't tried it yet cause suddenly my tx restart it self with this latest firmware.i have to figure it out first.
