If you wanted to use the sum of Left and Right channels for your mono source, we would have entered the
command 'syspara 2 4' instead of 'syspara 2 2'.
Trigger Script Example for Switching to Stereo Operation
Now we'll create a Trigger High Command Script, which will return the Omnia to stereo operation and put the
pilot back to 9% injection when the switch contacts open. In the Trigger HIGH Command Script box type in:
syspara 54 32 <enter>
This tells the processor to activate the 19 kHz pilot with the injection level set to 9.0%. “syspara 54” says to
edit the Pilot Level. The “32” says select 9.0% pilot level. Now type in:
syspara 2 1 <enter>
This tells the processor to switch the input to “Stereo.” “syspara 2” says to edit the Mono Mode setting. The
“1” says to select stereo mode.
When you are finished, the contents of the Trigger HIGH Command Script box should look like:
syspara 54 32
syspara 2 1
These four commands are now a completed script for Trigger 1. To test the scripts, click the Test button above
each edit box. If no errors or other displays are shown, then your script is ready to be used or saved. An error
indication typically indicates you have a “typo” in one of your command lines. Verify the command is correct
and that the index numbers for the parameters or parameter values are correct.
In order to use the scripts, they must be loaded into the Omnia-3. This is done by clicking Apply. Previously
entered scripts in the Omnia-3’s memory are then replaced by your new scripts. To save the edited Script Editor
scripts to the PC Card, click Save to Card. To recall previously edited scripts, click Load From Card. These can
then be sent to the Omnia-3 by clicking Apply.
To actually use the scripts you have just written requires that a sustained relay or a switch be connected between
trigger input 1 (pin 1) and ground (pin 5) on the Interface connector on the processor's back panel. Setting the
relay or switch on (shorting pins 1 and 5 together), then causes the Omnia-3 to follow the script for go low (the
unit switches to Mono Left/Pilot off operation). Opening the switch or relay will then cause the processor to
follow the go high script (the unit switches to stereo/pilot on operation).
Multiple operations, including ones that are vastly more complicated than what we have presented here, such as
simultaneously changing to different presets when changing from stereo to mono, can be completed at the flip
of any one of the eight switches or relays connected to the Omnia-3. And the eight relays or switches do not
have to be switched locally: Commands can even be initiated by a network satellite when a receiver with
contact closures is being used.
Different Ways to Use the Script Commands
There are two methods of using the script we just created. One is to use the scripts as Trigger Scripts,
responding to contact closures and opens as previously discussed. The other involves integrating the scripts into
the Omnia-3’s daypart table. Because the processor is flexible, it allows one to use the same script for both
options.
