Hi! Can the inverted S.PORT pin be used for OpenTX integration? The manual says to never connect power to SYS, but will it work with inverted S.PORT signal and ground only? |

He'd need to allow half duplex for that to work. the sys connector is TX, RX, G. So it's full duplex. I tried a few months ago to put a diode on the tx pin so it wouldn't receive the messages from inverted s.port, but it didn't work.

Hi, in theory it can be used. S.PORT is always running in half duplex mode. But wiring must be correct. VCC can't be connected there. I can help only with unmodified S.PORT wiring. |
