The ORI has
a 9VDC Center Negative input
Omniport In1/4” Jack to connect to the Omniport with a TRS cable
Relay Out1/4” Jack to connect to the switching input of the device that you want to control
The LED indicators on the ORI lights up
Power - when the ORI is connected to a power source
Tip - When the Tip connection is shorted to Ground
Ring - When the Ring connection is shorted to Ground
