Protector Operation Manual
Contact Closure + (pin 2)
Typical GPI connections for the ticker job require only one set of wires. Ad insertion equipment
should have some sort of contact closure, GPI output, or relay that will make a low (0V) or
simple ground. The Protector reacts to the GPI based on how you program it in the Event
Controller covered later in this manual.
Most contact closure outputs from the ad inserters will be labeled + and -; in reality, the Protector
won't care, but following these symbols will ensure proper connection.
Use the removable 10-pin plug (green Phoenix type). Strip your GPI contacts from the ad
inserter; insert stripped end into plug; tighten locking screws; plug 10-pin plug back into bottom
row of the GPI plug (labeled GPI).
