Make Sure Event is Running from 10a.m. to
8:30p.m.
Since sequences are edge triggered, it is possible to miss the time something is
supposed to happen if the power goes out while the trigger time occurs. The
power may come back on, with ScriptOS again knowing what time it is ( if you
have the external RTC),but it won’t know that it was supposed to have triggered
something in the past if you write the sequences as we have been.
This sequence is an example of when you have to make sure something is
running during a specific time. If the power goes out, ScriptOS must re-
determine if the event should be occurring. For this example, we will assume
that back ground music for an entire theme park needs to play between 10 a.m.
and 8:30 p.m. We will further assume that when
Output3
is on, the BGM is
also.

Communications Between Alcorn McBride
Equipment
All of our equipment can talk to each other via serial communications using our
own Alcorn 9 Bit Control protocol. This is useful if, for example, one V16+ is
in charge an entire attraction, including the PreShow, and it communicates
serially with two other V16+s that control two mainshows in two independent
theatres. It is also useful for simply adding expansion capabilities, such as
connecting an IO64 to a V16+, where the V16+ is the main Show Controller. In
this scenario, the IO64 adds 32 inputs and outputs to the V16’s existing 16.
Let’s use the IO64 as an I/O expansion box and see what the best way is to
integrate it into your show. For starters, you need to plug a Null modem cable in
between the V16+ and the IO64, using any available serial port (except the
