FC is a Succex E F4 v2.1
VTX is a AKK Infinite DVR
I connected SmartAudio port labeled TBS in vtx to T1, configured uart1 at ports tab as TBS SmartAudio.
Yes, I connected a lipo, imported vtx tables from akk (for some reason I can't set up the 1000mw, the max value seems to be 3 digits on the power field).
I checked continuity between TBS pad on the vtx and another T1 pad on the FC, seems to be fine.
