Pixhawk 6C mini telemetry wiring

Hi everyone,
I just recieved the PX 6C mini, the mapping is little confusing,

to get the CSFR telemtery to my Tx16S work, I have Telm1, Telm2, and FMU Debug on the side on the unit,
I tried to use FMU Debug by making Serial6_protocol = 23 and Serail6_options =0
not working and I don’t have connection to the mission planner at all!
then tried using Serial1 Telm1 by setting the Serial1_protocol = 23 and the Serial_options = 0
not working
AM I missing somthing here?

also how to setup two battery moniter?
do I need to have two power modules to be connected to the Pixhawk to read the voltages?
in this case I have only one Power in the pixhawk 6c mini, can I use any other port for the second power module?
the second battery is the 12S 9500mah connected to the ESC HW 130A platinum Opto and the ESC connected to the PIXhawk through the GPIO ch8

and my third issue after all that solved is getting RPM reading to my radio.
is this possible? or I am dreaming in future?

project is TradHeli RX using SuperP 14Ch ELRS and the CSFR.
thank you for any help

Solved thge 1st issue, get telemtry to my radio through the Debug FMU port.

now I try to set the servos but the weki not clear how to, it says set servoX_function to -1

is that will be for the all servos? same -1 ?

Thanks
Ozzy

Hello Ozzy,
I am not sure what servos you want to set to which function and on which wiki you refer. So please give always a little more infos about your problems.
If you want to setup a Tradiheli than it might be better also to ask your questions on the “Traditional Helicopter” Forum as there are more spezilized experts reading

Where are you seeing this? Setting the function to -1 configures the output to GPIO.

I got the servos now repsonding fine, I read that in the wiki, but I got it back to the Motors 1-8

the tail servo not repoding its moving only a very little and making noise, I think its about the Freq need to be set again.

Thank you

I got everything working now!
I found out that the tail Servo Xpert R2T trim = 700, Low = 800, and High at 1000
its not normal but hey its works!

anyone know if I get nether Power Module for my other 12s battery.
Can I use one of the Serials in the Pixhawk 6c mini?

I think I made mistake buying the mini since I need two power modules for two batteries
Thank you
Ozzy
