Programmer Port) on each box. You also need to select the Alcorn 9 Bit Control
protocol for both of these ports, as well as the same baud rate for both ports.
Since you have to set the baud rate and protocol in the IO64, this automatically
means you have to have two scripts, one for the V16+ and one for the IO64, but
need not program much else in the IO64 if desired.
There are three ways to divide programming between the two boxes. The first is
to program little or no sequences into the IO64, and directly access the I/O of the
IO64 from the V16+. The second is to program as many sequences as needed to
handle the I/O in the IO64, and simple start sequences back and forth between
the two boxes as needed. The third is to utilize a combination of both.
My recommendation is to keep things modular and place as many sequences as
necessary in the IO64. In other words, any programming that interfaces to I/O
in the IO64 should remain in the IO64, and the V16+ can be the main Show
Controller and just talk to the IO64 when necessary. This means the
programming will be more distributed, causing less show memory to be used up
in the V16+. It also makes it more readable because there are fewer sequences
in the V16+ that have anything to do with the IO64. In general, it’s modular.
Here are two example scripts to illustrate this idea. The first is for the V16+, the
second is for the IO64. The IO64 in this case is connected to the entrance and
exit doors and a PLC, which is controlling pyrotechnics.
The doors are simple output signals of the IO64, and the PLC both receives
output signals from the V16+, and sends input signals to the V16+.
As always, don’t forget to configure the IO64 port of the V16+ using AMI
Product Wizard. This allows you to address the IO64’s sequences by their full
names. See
Communicating with Alcorn McBride Show Controllers in Chapter
4 for more information.
