VCD to LRI2K frames
Frames are delimited by a start of frame (SOF) and an end of frame (EOF). They are
implemented using code violation. Unused options are reserved for future use.
The LRI2K is ready to receive a new command frame from the VCD 311.5 µs (t
sending a response frame to the VCD.
The LRI2K takes a Power-On time of 0.1 ms after being activated by the powering field.
After this delay, the LRI2K is ready to receive a command frame from the VCD.
Start of frame (SOF)
The SOF defines the data coding mode the VCD is to use for the following command frame.
