Runcam split mini 2 and Tramp HV wiring questions

#1
Hello all,
I'm setting up a freestyle quad with a runcam split mini 2 as the camera, a buzzer, Tramp HV as the VTX and a Ublox m8n mini as the GPS/compass . The FC is a Frsky edition Fireworks v2 with a r-xsr rx connected via the spi port. My concerns are around knowing exactly how to connect the camera controls for the camera. They list you can solder them to a uart's TX and RX pads but I have a camera control pad so can I use this? can I just attach it to the rx pad of the Camera but then what about the camera TX pad, what is this for? Audio?
Also i'm pretty sure I can attch the tramp tremetry wire to the smart port pad and it should be work if I configure betaflight right.

I'm using the 8v 1 amp BEC to power both as it is filtered and combined maximum power draw should be .9 amps at 8v. Also that is at 600mv transmit strength and I am limited to 25mv in my country so power draw should be much less for me.

For the camera control, you will need a full UART (both Rx and Tx) - the smart audio/tramp telemetry is used to control the VTx channel, band and power output.
