Governor with SBUS receiver w/telemetry

[Romis]

I have a Spirit (classic) connected by SBUS to Orange RX with telemetry. Throttle cable goes from ESC to RX, everything works fine, currently I`m using ESC governor but I want to try Spirit governor and connect Orange RPM sensor to the telemetry port of RX to see RPM. Question is - do I have to connect the RPM sensor directly to Spirit (as per manual) if I want to activate governor in Spirit? OR will the SBUS line give RPM data to Spirit in case I connect sensor to the telemetry port of RX (this should be preferable in order to use telemetry RPM).
Wiring: ESC (YEP)=>throttle signal=>RX Orange=>SBUS line=>Spirit FBL unit
OR - if I connect RPM cable to Spirit unit will RX receive RPM signal by SBUS from Spirit?

Unfortunately this is not possible due to technical difficulties.

Telemetry data are transmitted too slow to be useable for governor.
So RPM sensor must be always connected to the unit directly.
