CLI
resource
to locate RX3 pin name
RX3 pin is
C11
then
resource SERIAL_RX 3 none

Tips
If FC has PINIO power switch built-in, e.g. F722-SE, F722-mini, no need to use this VTX PINIO function.
VTX PINIO would cut 5V output, so don’t power your FC via VTX 5V pad if you want to use this function.
VTX Power OFF
VTX Power ON
CMS control
Protocol: Tramp(TR)
*** CMS would override the button control if CMS control is enabled.
TR power level vs VTX power level
TR PIT -- VTX PIT
TR 25 -- VTX 25mw
TR 100 -- VTX 200mw
TR 200 -- VTX 200mw
TR 400 -- VTX 400mw
TR 600 -- VTX 800mw
CLI
vtx_low_power_disarm = OFF
Allowed values: OFF, ON, UNTIL_FIRST_ARM
If ON and the flight controller is disarmed, the video transmitter output power will be set to 25mw
Otherwise, the video transmitter output power will be set to the configured value.
