42AXIS 216FD - The I/O Terminal Connector

The I/O Terminal Connector

Pinout and Interface

The 4-pin I/O terminal connector provides the interface to:

•1 transistor output

•1 digital input

•auxiliary power and GND

The terminal connector is used in applications for e.g. motion detection, event triggering, time lapse recording, alarm notification via email, image storage to FTP locations, etc.

•Input - for connecting e.g. a push button. If the push button is pressed, the state changes and the input becomes active (shown under Event Configuration > Port Status).

•Output - connects e.g. an alarm device that can be activated by Output buttons on the Live View page, or by an Event Type. The output will show as active (Event Configuration > Port Status) if the alarm device is activated.

I/O terminal connector:

Pin	Function	Description
4	Transistor Output	With a maximum load of 50mA and a maximum voltage of 24V DC, this out-
		put has an open-collector NPN transistor with the emitter connected to the
		GND pin. If used with an external relay, a diode must be connected in parallel
		with the load, for protection against voltage transients.
3	Digital Input	Connect to GND to activate, or leave floating (or unconnected) to deactivate.
2	3.3V DC	Can be used to power auxiliary equipment, max 50mA.
1	GND
