Crossfire/Tracer connection using CRSF
All Unify PRO32 do have a full serial interface which has extended functionality compared to Smartaudio
which is just a onewire protocol.
●
Set the EVO Dataport 1 to CRSF by menu or Agent X/L
●
Select a free output pin pair capable for CRSF and connect them using CRSF
Wiring example
Now you can control your Unify by the My VTX menu or by it’s own device menu by Agent lite etc.
Smart Audio or CRSF for the VTX?
Both protocols had their advantages and disadvantages:
●
SmartAudio
○
Single wire connection. Saves one PWM output (useful on a wing)
●
CRSF
○
Fully configurable by LUA, FUSION, Agent X, etc.
○
CRSF readout - let you use PITMode on a switch or navigate through OSD without
the need for a FC, link stats read out and more
Control by PWM channel
For setups without flight control and receivers that do not have CRSF capability, such as R/C cars or boats,
we have enabled a control for the button via PWM control. You can connect a PWM channel to the CRSF
RX1 port and simply move a switch from low to high to press and high to low to depress the button. The
single PWM channel is the most simple way of using a video transmitter. The menu control is identical to
using the button. Follow the instructions from the
to set up the Evo.
