Trigger Interface and Script Editor
Overview of the Trigger Script Editor
The Omnia 4.5 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 rear-panel

Using Trigger Scripts, you can make the Omnia 4.5 do things with contact closures that would normally
need to be done either by manual intervention at the front panel, or via Omnia 4.5 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, the inputs normally sit at
