configuration information now becomes a tool which we can use to create
the sequences that will make our theatre run.
The sequence entry we are about to perform will result in a completed V16+
script consisting of a few sequences. Obviously with nine unused inputs,
eight unused outputs and 212 unused sequences there is plenty more we can
make this V16+ do. But these sequences will give you an idea of the
V16+'s capabilities and form a rudimentary but complete theatre control
system.
One of the most powerful aspects of the V16+ is the inter-relationship that
sequences can have amongst themselves. Several of our example sequences
will illustrate the flexibility this gives us.
The first sequence for which we will enter events is our Startup sequence.
The function of Startup is to initialize outputs to known states. As you
recall, this sequence is executed automatically when the V16+ and other
equipment is first powered up. It is also executed whenever the first push
button on the V16+ front panel is pressed.
The very first activity in our startup sequence must be to reset other
important sequences. Since many of our sequences operate the same
outputs, allowing some other sequences to run during Startup could cause
interesting and unpredictable interactions. When first powering up the
V16+, of course, the other sequences will not be running, but they may be if
the start button is pushed later during the day.
Startup continues by initializing all of the V16+ outputs to a known state.
When the V16+ is first powered up all of its outputs are initialized to off;
however, since the Startup sequence can be executed at any time, the state
of the outputs is unknown. We therefore initialize all of them. Do this
using the Off and On events in the Event column and the English names of
the outputs in the Data1 column. Using these commands, we turn off the
operator console cue light, close the exit doors, turn off the projector start
and douser lines and turn off the audio mute line.
We also want to set the entrance doors to their normal rollover state, which
in our case is going to be open. Before we do this we should blink the
warning lights for 5 seconds to alert anyone near the doors that they are
going to move. Do this using the Blink event, putting the warning light
name in the Data1 column and a one second blink rate into the Data2
column.
