LRI64 TO VCD FRAMES
Response Frames are delimited by a Start of
Frame (SOF) and an End of Frame (EOF) and are
implemented using a code violation mechanism.
The LRI64 supports these in the one subcarrier
mode, at the fast data rate, only.
The VCD is ready to receive a response frame
from the LRI64 before 320.9µs (t
sent a command frame.
