TRENDnet TV-IP322P manual Gpio Terminal Application, Connector Pin Assignment, AC Power

A.2 GPIO Terminal Application

Typically used in association with programming scripts for developing applications for motion detection, event triggering, alarm notification via e-mail, and a variety of external control functions. The 8-pin I/O Terminal Block is located on the rear panel and provides the interface to: a photo- coupled switch output, a photo-coupled input, and RS-485 interface. The RS-485 is typically used for pan/tilt control.
