Axis Communications 210A The I/O Terminal Connector, Pinout and Interface, Function, Description

AXIS 210/210A/211/211A - The I/O Terminal Connector 47

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 e-mail, 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.

DC-Iris control cable (AXIS 211/211A only).

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/max 5W. 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 210A/AXIS 211/211A is powered by PoE.
