4.2 Operating instructions for smartaudio functionality

1. Connect video transmitter with BETAFLIGHT flight controller

1）Solder “Video IN” yellow wire with “video OUT” port on flight controller, solder

black GND wire with a spare GND port on flight controller, solder smartaudio wire

with one spare UART TX port on FC, for example UART3 or UART 5.

2） Connect flight controller with computer via USB cable, and open Betaflight app

2. Settings in betaflight app

After connected FC with computer and enter Betaflight app, click “connect” in

app→click “Ports”→ select “TBS SmartAudio” on UART5“Peripherals” listing→ click

“Save and Reboot” to save setting. Please see below image for your reference.

Change vtx setting by RC transmitter

1) Power on video transmitter, flight controller and video receiver monitor or goggle,

make sure video transmitter and video receiver monitor/goggle are in same channel,

open OSD and you can see below image 1 from video receiver monitor/goggle.

Understanding your transmitter display:

① Device status: F (Freestyle mode, there is a race mode)、

A8：Band A 8th channel,、5725: (Channel Frequency in MHz), 25: (Output power in

mW).

②Band setting, you can switch between A, B, E, F, R bands

③Channel setting, you can switch between 1~8 channels

④Output power setting, you can switch between 25、200、500 and 800 numbers,

the VTX output 25mW, 200mW and 600mW, 25mW corresponding number 25,

200mW corresponding number 200 and 600mW corresponding number 500.

⑤To save your settings, move cursor to SET→ select YES →save setting

⑥SMARTAUDIO configuration

Enter “SA CONFIG” you can see below image，you can select freestyle mode or race

mode for the vtx and you can turn on or turn off pit mode.

⑦OP model: FREE mode or RACE mode

⑧While under FREESTYLE mode or RACE MODE, pit mode is off “---”，you can turn

on pit mode and “---” will be changed to “PIT”，VTX output very low power in current

channel and it won’t interfere other quads.
