AXIS 210/211 - The I/O Terminal Block

The I/O Terminal Block

Pinout and Interface

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

• 1 transistor output

• 1 digital input

• auxiliary power and GND

The terminal block 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.

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 con-

nected to pin 1 (GND). If used with an external relay, a diode must be

connected in parallel with the load, for protection against voltage tran-

sients.

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.

1 GND

Terminal block connector. Note that the

pins are numbered 1-4, right to left.
