Why is a ground wire mandatory in RS-232 wiring?

RS-232 requires, in addition to RX and TX, a common mass between the radio and the adapter. If it is missing, the adapter appears to connect, but delivers no data or only sporadic data – the most common wiring error with Universal-Installations.

Always connect the ground connection before troubleshooting.

Am I allowed to use the adapter on my airplane?

The plug-and-play adapters are simply inserted, not permanently installed – no modifications to the aircraft's wiring are required, and they can be removed at any time without leaving any residue. This is straightforward for ultralight and experimental aircraft.
