Creating a Trigger Script
Now that the scripting commands have been defined, let’s put them to work to create a Trigger Script. We’ll use one
of the most commonly requested operations that FM broadcasters want to easily accomplish: switching between
mono and stereo operation.
This procedure can of course be done by manually using the Omnia-6EX front panel controls to turn off the 19 kHz
pilot tone and to switch the input from stereo to mono left. But a far easier method is to use the Trigger Script Editor
to create two scripts that can be loaded into the processor to run in response to a single relay contact closure or open.
The following scripts do just that—set the Omnia-6EX to automatically switch to mono in response to a sustained
contact closure and to then return to stereo operation when that same contact is opened.
In scripts, all lines that begin with “syspara” must be followed by two numbers that identify the parameter ID
number that is being set and that ID number's new value. The value numbers and their settings for the Pilot Level
were also shown. To list the values and parameter settings for any parameter, type in sysparavalues followed by a
space and then the parameter’s “syspara” number.
(The “sysparas” table lists all of the available system parameter numbers.)
Trigger Script Example for Switching to Mono Operation
In this example, we'll configure Trigger Input # 1 to switch the Omnia-6EX into mono operation when the contact
closes and switch back to stereo when it opens again. To create this script, open up the Script Editor and click radio
button #1. Now click in the lower edit box to begin entering the Trigger 1 “Trigger Low” script. Type:
syspara 54 1 <enter>
This command sets the processor to turn off the 19 kHz pilot tone when it is run. “syspara 54” says to edit the Pilot
Level. The “1” says select Off. Next, type in:
syspara 2 2 <enter>
This command sets the processor to switch the input to “mono left” when run. “syspara 2” says to edit the Mono
Mode setting. The “2” says select mono left.
When you are finished, the contents of the Trigger LOW Command Script box should look like:
syspara 54 1
syspara 2 2
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> (syspara<space>9<space>32
This tells the processor to activate the 19 kHz pilot with the injection level set to 9.0%. “syspara 9” says to edit the
Pilot Level. The “32” says select 9.0% pilot level. Now type in:
