Trigger Interface and Script Editor
Overview of the Trigger Script Editor
The Omnia-3 Remote Control software contains a special script editor that allows the programming of
complicated system parameter changes, which can be "triggered" by logic state changes on the re
ar-panel
"Interface" connector.

Using Trigger Scripts, you can make the Omnia-3 do things with contact closures that would normally need to
be done either by manual intervention at the front panel, or via Omnia-3 remote control. There are EIGHT
Trigger Inputs available, and they respond to voltage levels
on the rear-panel "Interface" connector.
Trigger Control by Dry Contact Closures
The simplest way to manipulate a Trigger Input is through simple contact closures to ground. Connecting a
Trigger Input to ground initiates the programmed function associated with the "Trigger LOW" command, and
moving the connector pin from a grounded to a floating condition issues the "Trigger HIGH" command.
Trigger Control by Applied Voltages
The Trigger Inputs are also capable of operating with a DC voltage applied, as long as such voltage does not
exceed 25 volts DC. Applied voltages that are more than +1.25 volts DC on the trigger input result in a Trigger
HIGH state, while voltages less than +1.25 volts result in a Trigger LOW state. Therefore, if +12 volts DC is
applied, a logic "1", or Trigger HIGH is sensed. If –12 volts DC is applied, a logic "0", or Trigger LOW is
sensed. When nothing is connected to the Trigger Inputs, they normally float at approximately 3.5 volts, which
is a logic HIGH.
What Can Trigger Scripts Control?
Virtually any aspect of the Omnia-3 operation can be controlled using the Trigger Script function. Therefore,
we'll explain some of the different types of operations that can be performed, and the different types of
commands that are required to perform each one.
