Omnia-6ex Use and Operation Manual – V: 1.2096Trigger Interface and Script EditorOverview of the Trigger Script EditorThe Omnia 6 Remote Control software contains a special script editor that allows the programming of complicatedsystem parameter changes which can be “triggered” by logic state changes on the rear-panel “Interface” connector.“Edit Trigger Scripts” dialog box as opened under “Options”, “Edit Trigger Scripts”Using Trigger Scripts, you can make the Omnia 6 do things with contact closures that would normally need to bedone either by manual intervention at the front panel, or via Omnia 6 remote control. There are EIGHT TriggerInputs available, and they respond to voltage levels on the rear-panel “Interface” connector.Trigger Control by Dry Contact ClosuresThe simplest way to manipulate a Trigger Input is through simple contact closures to ground. Connecting a TriggerInput to ground initiates the programmed function associated with the “Trigger LOW” command, and moving theconnector pin from a grounded to a floating condition issues the “Trigger HIGH” command.Trigger Control by Applied VoltagesThe Trigger Inputs are also capable of operating with a DC voltage applied, as long as such voltage does not exceed25 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 isconnected 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 6 operation can be controlled using the Trigger Script function. Therefore, we'llexplain some of the different types of operations that can be performed, and the different types of commands that arerequired to perform each one.
