PLEASE HELP to send PWM signal from TBS Crossfire on AUX4
#1
When I toggle my right bottom switch on remote control (AUX4), I need PWM signal from TBS receiver to the cam switcher to be sent. Please tell me how can I setup TBS receiver so it will send this PWM signal?

I use Radiomaster TX12 transmitter. I also have TBS Crossfire Nano:

If I understand correctly, in this video (https://youtu.be/zEWlYpDZuS0?t=1155) at 19:15, the guy is binding (mapping) receiver's phyisical pins 1-8 to receiver's channels (among them my AUX4). Although he has TBS Crossfire with more pins (CH1-CH8) and I have just TBS Crossfire Nano (CH1-CH4), but logic must be the same.

So if I map Output4 (on my image it seems to be third pin from the top) to signal CH4 (or possibly CH8 since ch1-ch4 are controls, ch5-ch8 are AUX maybe), will it produce signal on that pin? Please clarify what should I do to obtain the PWM signal.
Thank you in advance!

When you say CH1-CH4 for controls and CH5-CH8 or CH5-CH12 for Aux then you are talking about a CRSF protocol based interface with the FC that is done via a UART to Ch1 and Ch2 on the NanoRX.

Ch3 and Ch4 on the NanoRX can still be controlled as a PWM channel via the Radio. Basically this CRSF communication is from Crossfire TX to the Nano RX and will output a standard 50Hz PWM signal to power a servo or any pwm controlled device. Basically you can set this up using a switch on your radio.

Thank you for explanation, kafie1980! This seems logical. I'll try to set this up
