Category 4: Action Logic
This fourth class of logic function in the WheatNet-IP system includes system
events such as Salvos and Momentary Connections. Action logic is intended to
force crosspoint connection changes. Perhaps you have an Air studio that
undergoes a major change in signal connections when the morning show finishes.
Instead of having the talent go through and change all the source and destination
connections individually at each shift change, you could create a Salvo that makes
all of the required changes at once. Furthermore, you can use a logic connection
to a button to fire the Salvo itself, so all that your operator needs to know is to push
the button at shift change. What could be easier?
For an example, let’s assume you have created a Salvo to change out your
studio configuration from Morning Drive to your 10 o’clock show, and you’ve
cleverly called it “10AM.” You are planning to use a switch panel in your studio
to fire the Salvo, and you’re going to wire the “10AM” switch on the switch panel
to logic port #4 on BLADE #5.
Here’s how to do it: First wire up the normally open terminals of the switch to
pins #1 and #5 on the first RJ-45 logic port of BLADE #5. In the WheatNet-IP
Navigator GUI, click on the icon for BLADE #5 in the System Pane, and then click
on the LIO Info tab. On LIO #4 (the 4th line) double click on the Fire Salvo box
to open the window and click on the “Fire Salvo” check box. In the drop down
window, scroll and select the “10AM” Salvo and click on the OK button.
To test this out, switch to the crosspoint grid view of the GUI and watch the
cross-points switch on the grid as you press the switch (be sure to do this at a safe
time as you will actually be switching audio and can mess up a show On - Air).
You can also use action logic to make a crosspoint change (hint: use a Salvo
of one signal) that switches the source for a destination, or to make a temporary
crosspoint change that substitutes a source to a destination for as long as the button
is held down. The latter is particularly useful in Talkback/Intercom types of
situations.
