Settings
Press button-A to select RF output levels, 0 (blue LED)= 0.1mw pitmode, 1=25mw. 2=200mw, 3=800mw
Press and hold the button-B for 2 seconds to enter the frequency setting. Frequency LED blinks
Press the button-B to select the frequency (only 1258 and 1280 can be selected on US 2CH version)
When the LED blinks at new frequency, no RF output on this frequency.
New frequency and output will be enabled if no button action within 3 seconds
CMS control
Connect âRXâ to any spare UART-TX of flight controller, enable âVTX(Tramp) protocolâ on corresponding UART.
Copy and paste following command into CLI of BF4.1 or later release
