In Null Startcode only systems, you could usually get away with this, but it's not enough for reliable RDM operation. 0x00+Framing Error only tells you that the line has been held low for about 40us.

During the discovery period, it's common to see the line held low for >40us due to response collisions.

Building a reliable RDM device requires a lot of work tuning the DMX receive engine.
