I/O connector

Note

For technical speciﬁcations, see page 53.

I/O terminal connector - Use in applications for e.g. motion detection, event triggering, time lapse recording and alarm notiﬁcations.

In addition to an auxiliary power and a GND pin, the I/O terminal connector provides the interface to:

•Digital output — For connecting external devices such as relays and LEDs. Connected devices can be activated by

the VAPIX® Application Programming Interface, output buttons on the Live View page or by an Action Rule. The

output will show as active (shown under System Options > Ports & Devices) if the alarm device is activated.

•Digital input — An alarm input for connecting devices that can toggle between an open and closed circuit, for

example: PIRs, door/window contacts, glass break detectors, etc. When a signal is received the state changes and

the input becomes active (shown under System Options > Ports & Devices).

Note

The I/O connector is connected to the housing (fan/heater) on delivery, and will trigger an input port event to indicate

a fan or heater error when activated. See Events, on page 32 for information on how to set up an event.

Function Pin Notes Speciﬁcations

GND 1Ground

3.3 V DC Power 2Can be used to power auxiliary equipment.

Note: This pin can only be used as power out.

Max load = 50 mA

Digital Input 3Connect to GND to activate, or leave ﬂoating (unconnected)

to deactivate.

0to+40VDC

Digital Output 4Internal connection to ground when activated, ﬂoating

(unconnected) when deactivated. If used with an inductive

load, e.g. a relay, a diode must be connected in parallel with

the load, for protection against voltage transients.

Max load =100 mA

Max voltage = +40 V DC
