Video Transmitter Tab

Configure the video transmitter (VTX) using this tab. It allows setting of the power, band, channels, etc.

note

When using a DJI or Walksnail video transmitters, this tab can be ignored. This is only used for analog and HDZero video transmitters.

VTX tab

It is important to have VTX Telemetry (SmartAudio or Tramp) enabled in the Ports tab to use this feature.

Selected Mode

Option	Description
Enter frequency directly	When enabled, the Configurator will send a frequency value in place of the habitual band/channel. For this to work the VTX must support this feature.
Band	Select the band to use.
Channel	Select the channel to use.
Power	Select the power level to use.
Pit Mode	When enabled, the VTX enters in a very low power mode to let the quad be on at the bench without disturbing other pilots. Usually the range of this mode is less than 5m. NOTE: Some protocols, like SmartAudio, can't enable Pit Mode via software after power-up.
Pit Mode frequency	Select the frequency to use in Pit Mode.
Low Power Disarm	When enabled, the VTX uses the lowest available power when disarmed (except if a failsafe has occurred). On - Go to lowest power possible when disarmed Off - Always on the set power level On until first arm - Stay on the lowest power possible until the first time the quad is armed, then go to the set power and stay there indefinitely

Option	Description
Device ready	Indicates if the Flight Controller is talking to the VTX.
VTX Type	The type of telemetry that is used to communicate with the VTX.
Band	The current band that the VTX is set to.
Channel	The current channel that the VTX is set to.
Frequency	The current frequency that the VTX is set to.
Power	The current power level that the VTX is set to.
Pit Mode	Indicates if the VTX is in Pit Mode.
Pit Mode frequency	The frequency that the VTX is set to when in Pit Mode.
Low Power Disarm	Indicates if the VTX is in Low Power Disarm mode.

Option	Description
Number of bands	The number of bands that the VTX supports.
Number of channels by band	The number of channels that the VTX supports.
Name, Letter, Frequencies	This table represents all the frequencies that can be used for the craft's VTX. It's possible to have several bands and for each band it is required to configure: Имя - The name of the band, like `BOSCAM_A`, `FATSHARK` or `RACEBAND`. Letter - Short letter that references the band. Factory - This indicates if it is a factory band. If enabled AlphaFly sends to the VTX a band and channel number. The VTX will then use its built-in frequency table and the frequencies configured here are only to show the value in the OSD and other places. If it is not enabled, then AlphaFly will send to the VTX the real frequency configured here. Frequencies - Frequencies for this band. Remember that not all frequencies are legal in all regions.
Number of power levels	The number of power levels that the VTX supports.
Power levels	This table represents the different values of power that can be used for the VTX. They are divided into two: Value - each power level requires a value that is defined by the hardware manufacturer. Ask the manufacturer for the correct value or consult the AlphaFly wiki of VTX Tables to grab some samples. Label - put here the label for each power level value. It can be numbers (25, 200, 600, 1.2), letters (OFF, MIN, MAX) or a mix of them.

Option	Description
Сохранить	Save the changes to the Flight Controller
Save to file	Save the VTX settings to a JSON File
Load from file	Load the VTX settings from a JSON File
Load from clipboard	Load the VTX settings from the clipboard. Has to be a valid JSON.
Save Lua Script	The 'Save Lua Script' button will allow to save a `mcuid.lua` file containing the VTX table configuration that can be used with the AlphaFly TX Lua Scripts. Version 1.6.0 and above can use the file as is, but for older versions of the scripts it should be renamed to match the model name on the TX.
