The TBS UNIFY PRO32 is a compact, high-quality video transmitter (VTX) designed as a successor to the popular TBS UNIFY PRO line. It offers improved robustness, reduced size, lower power consumption, and enhanced features for multirotor applications.

Function Description:

The TBS UNIFY PRO32 serves as a video transmitter, converting video signals from a camera into radio frequency (RF) signals for wireless transmission to a receiver. It supports a wide range of channels and power levels, allowing users to select optimal settings for various flying environments and regulations. The device is designed for ease of installation and configuration, offering multiple control methods including an onboard button, SmartAudio 2.1, CRSF, and PWM. Its "CleanSwitch" feature ensures minimal interference during power-up and channel changes, making it suitable for racing and multi-user environments. PITMode allows for very low output power, preventing interference during setup or team racing.

Pit Mode Deactivation: Press power for 5 seconds during runtime or use Smart Audio V2.1
Pit Mode to Flight Mode: On-board button, SmartAudio 2.1 or CRSF Command

Usage Features:

Button Menu Control: The device features an onboard button for configuration. A 3-second press toggles between categories (e.g., channel, band, power), while a short press toggles between settings within a category. LED colors indicate the menu state.
Unlock & Power Select Mode (HAM Users Only): Pressing the button for approximately 30 seconds unlocks the VTX for use with all frequencies. Once unlocked, power levels can be selected. To re-lock, press the button for 20-25 seconds in the band select menu.
SmartAudio 2.1: This single-wire UART protocol, developed by TBS, allows OSD to VTX communication. It enables configuration of VTX settings via a flight controller (FC), TBS Crossfire/Tracer, or PNP PRO OSD. SmartAudio 2.1 introduces improved PITMode control.
CRSF: A high-bandwidth, low-latency full-duplex serial data transmission protocol designed by Team BlackSheep. It offers comprehensive configuration via LUA scripts, FUSION, Agent X, etc., and allows for PITMode control via a switch, navigation through the Unify Evo OSD without an FC, and link stats readout.
Crossfire/Tracer Direct Connection: The VTX can be directly controlled by a TBS Crossfire/Tracer receiver without needing an FC. This is useful for setups with no free UARTs or when direct control is preferred. Connections can be made using either SmartAudio or CRSF protocols.
PWM Channel Control (Unify PRO32 Nano only): A simplified method using a single PWM channel from the receiver to modify VTX channels. Short presses increase the channel, long presses (>3s) increase the band, and longer presses (>5s) reset the VTX channel to A1.
Barcode Control: The VTX can be controlled via barcodes scanned by the camera. This feature allows for quick activation of PITMode, power-up, and channel changes by presenting a barcode in front of the camera. The Unify Pro32 Nano supports barcode reading since HW revision 1.0 and FW 1.05.
PITMode: A special mode where the VTX operates at extremely low output power (less than 0.1mW) to prevent interference during events or setup. It can be activated/deactivated via the button, SmartAudio, or CRSF.
CleanSwitch: This feature ensures that the VTX remains at its lowest power output (less than 0.1mW) when powering up or changing channels. This prevents bursts of interference that typically occur with other VTXs, ensuring interruption-free racing.
Frequency and Power Table: A detailed table outlines available channels, bands, and corresponding frequencies, along with power levels. Grey fields indicate default factory settings. Orange selections require a HAM license, while black selections are available on special request with prior legal body approval. The VTX prevents accidental selection of illegal channels or power levels.

Maintenance Features:

Firmware Upgrade (Unify PRO32 HV only): Firmware can be updated via USB using the TBS Agent X software. Users are advised to update their Unify to FW 1.16 or later versions for full functionality.
Force Device into Bootloader Mode: In rare cases, the device can be forced into bootloader mode by bridging two specific pads on the unit before powering it up. This is not required for regular operation.
Installation / Mounting: Proper mounting is crucial for heat dissipation. The VTX should be mounted with slight pressure against a flat piece of carbon for best results, ensuring contacts are isolated to prevent short circuits. This allows the VTX to run for extended periods without reducing output power. The VTX automatically reduces output power before reaching critical heat levels.
Soldering Precautions: When soldering to the tabs, temperatures should not exceed 350°C for more than 3-5 seconds to prevent damage.
Button Fragility: The tactile button is fragile; users are advised not to use hard or pointy objects to change channels to prevent permanent damage.
Voltage Spike Protection: If using the VTX on 13V, proper filtering is recommended to prevent damage from voltage spikes.
