General Purpose Interface (Gpi) (Db-9F); Powering Up - Omnia Stereo Audio Processor Installation And Operation Manual

General Purpose Interface (GPI) (DB-9F)*

This DB9-female connector serves as a four-input, optoisolated interface to the Omnia's internal Trigger Script
functions*. Four of the pins are "trigger" inputs, one is a bias voltage input, one is a +5V power output, and the
remaining three are "ground." The trigger inputs can be used to dynamically alter the Omnia ONE's operation in
response to logic transitions on the interface connection. Virtually any parameter of the Omnia can be controlled
using the Trigger Scripts.
The Trigger Script Interface is a standard component of the Omnia ONE Remote Control application. Full details,

including connector pinout, are covered in Appendix C, starting on
*Please note that the GPI and Trigger Script functionality are not yet implemented in the current software but will be
available with a free downloadable software update. Please check the Omnia website for new software
announcements, download links and manual updates at: http://www.omniaaudio.com/

Powering Up

Now you are ready to power up the Omnia ONE for the first time.
Connect AC power to the unit using the appropriate supplied power cable for your location.
(There is no power switch!)
When the Omnia ONE is first powered on, audio will appear at the analog audio outputs in approximately ten
seconds. The AES/EBU and Livewire outputs also become usable at this time however full initialization of the
digital ports is not complete for several more seconds and a small audio glitch may be heard when the final sample
rate converter initialization is complete. Once the boot process is finished the following Main Menu will appear:
