E1.11 allows frames of any length from 1 to 512 slots.

One other note, from the scope image, it looks like the responder may be enabling its line driver too soon. The responder should not start responding for at least 176us, and based on the slightly higher voltage levels I think it may be enabling the line drivers immediately after the request is finished.
As far as I remember there's delay_us(170) after parsing RDM request and before enabling transmitter in my responder program, so it shouldn't enable driver at that time. I need to check this one more time, though. Thanks for the advice!
