42AXIS 210/211 - 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 doorbell. If the doorbell 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.

DC-Iris control cable (AXIS 211 only).

		Terminal connector. Note that the
		pins are numbered 1-4, right to left.
Pin	Function	Description
4	Transistor Output	With a maximum load of 100mA and a maximum voltage of 24V DC, this output
		has an open-collector NPN transistor with the emitter connected to pin 1 (GND).
		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	Auxiliary DC Power Input	7-20 VDC/min 7W. Electrically connected in parallel with the PS-K power
		connector, this pin provides an auxiliary connector for mains power to the unit. If
		the unit is powered via this pin, a fuse should be used (rating: 1A Slow).
		This pin can also be used to power auxiliary equipment, max 100mA, but note that
		this is not possible when the AXIS 211 is powered by PoE.
