• 1x Dipole antenna_SMA, center freq 1240MHz

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 “RX” to any spare UART-TX of flight controller,  enable “VTX(Tramp) protocol” on corresponding UART.
• Copy and paste following command into CLI of BF4.1 or later release
