AXIS P5522 PTZ Dome Network CameraMulti-Connector Cable (sold separately)Multi-Connector Cable (sold separately)When connecting external equipment to the Axis product, a multi-connector cable (available from Axis) is required in order tomaintain the product’s IP rating. The multi-connector cable can be purchased from your Axis reseller.Connect the multi-connector cable to the product’s multi-connector (see page 4 ). The cable provides the following connectors:NoteSee page 53 for technical specifications.Power connector - 3-pin terminal block used for power input. See image below.Audio in (pink) - 3.5 mm input for a mono microphone, or a line-in mono signal (left channel is used from a stereo signal).Audio out (green) - 3.5 mm output for audio (line level) that can be connected to a public address (PA) system or an active speakerwith a built-in amplifier. A pair of headphones can also be attached. A stereo connector must be used for the audio out.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 theVAPIX® Application Programming Interface, output buttons on the Live View page or by an Event Type. The output willshow as active (shown under Events > Port Status) 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 inputbecomes active (shown under Events > Port Status).Function Pin Notes SpecificationsGND 1 Ground3.3 V DC Power 2 Can be used to power auxiliary equipment.Note: This pin can only be used as power out.Max load = 250 mADigital input — Connect to GND to activate, or leave floating(unconnected) to deactivate.0 to +40 V DCConfigurable(Input or Output)3–6Digital output — Internal connection to ground whenactivated, floating (unconnected) when deactivated. If usedwith an external relay, a diode must be connected in parallelwith the load, for protection against voltage transients.Max load =100 mAMax voltage = +40 V DC47
