PitMode
PitMode is a mode where the video transmitter only runs on an incredibly low output power. This prevents
interference with others at events, while still allowing a minimum of visibility for emergency last-minute
setting changes.
With the TBS UNIFY PRO32 line, Pit Mode has been slightly modified in behavior. The main button on the
video transmitter is used to toggle pitmode flag at power-up, and SmartAudio / CRSF can modify this flag
as well. Smart Audio / CRSF can enter also enter pit mode during runtime using the power setting 0mW,
which will not modify the flag (the VTx will never power up at the 0mW power setting). To leave pitmode
during operation, simply set your desired power setting using Smart Audio, CRSF or the button menu.
SmartAudio 2.1
SmartAudio is a protocol developed by TBS for OSD to VTx communication. SmartAudio is a single-wire
UART protocol, running over the Audio-wire. All newer generation OSDs at TBS, and all UNIFY PRO series
VTX, and all modern flight controllers support SmartAudio!
With the UNIFY PRO32 line we have launched SmartAudio V2.1. Over the regular SmartAudio, it changed
control for PitMode in operation to a switch(on / off) rather than a flag that is refreshed on reboot.
If you are a OSD or VTx developer interested in adding support for SmartAudio, please check our
SmartAudio specification​ . SmartAudio is a free-to-use protocol. If you'd like to use "TBS SmartAudio" in
your marketing, you may contact us for licensing options:

CRSF
CRSR is a protocol designed by Team BlackSheep and championed through the TBS Crossfire remote
control system. It has been integrated into most popular remote controls, is a incredibly high bandwidth
(low latency) full duplex, serial data transmission protocol. It comes with native functionality such as OTA
(over the air) firmware upgrades, localized configuration menus and a smart routing protocol.
With the advent of the TBS UNIFY PRO32, for the first time in FPV history does a VTx now support this
functionality. We can configure channel, output power and pitmode settings. Additionally, software
updates via the TBS Crossfire platform are now possible.
