7-16 Application Notes
Our next sequence is StartShow. StartShow is actuated by the start button
on the theatre operator's console. Our theatre presentation is designed so
that it can automatically loop all day long after the first show is manually
started. To run the first show of the day the operator presses the OCC start
button and StartShow begins execution. Configure StartShow to have the
OCCStart
input as its start trigger and don’t forget to check the Loop
Enable checkbox to assure that we continually check for the projector
ready-line.
StartShow uses the LCD display command to inform us that it is waiting for
the projector ready line. Next it checks to see if the projector ready line is
active. If it is not, it jumps over the next line to the
Nop
at the end of the
sequence, labeled
loop
. As soon as the sequence reaches the end, it begins
again at the beginning. When the projector is ready, StartShow confirms
that the DVD Players have been searched to the correct frame, starts the
main show sequence, Showtime, and resets itself so that it won’t interfere
with other sequences.
