AXIS 207 - 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.

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 2 (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 GND

1 Auxiliary DC Power Input 5VDC/min 2.5W. Electrically connected in parallel with the PS-L power connector,

this pin provides an auxiliary connector for mains power to the unit. This pin can

also be used to power auxiliary equipment, max 50mA.
