39AXIS 214 PTZConnectionsI/O inputs and outputsThe 4-pin I/O terminal connector provides the interface to:• 1 transistor output• 1 digital input• auxiliary power and groundThe I/O terminal connector is used in applications for e.g. motion detection, event triggering, time lapserecording, 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 theinput 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 Viewpage, or by an Event Type. The output will show as active (Event Configuration > Port Status) ifthe alarm device is activated.Schematic connection diagramConnecting audio equipment1. Connect a microphone (not supplied) to the LINE/MIC IN socket.2. Connect a loudspeaker (not supplied) to the LINE OUT socket (amplified speakers only).Function Pin no. Description PinoutsTransistor Output Pin 4 With a maximum load of 100mA and a maximum voltage of 24V DC, this out-put has an open-collector NPN transistor with the emitter connected to theGND pin. If used with an external relay, a diode must be connected in parallelwith the load, for protection against voltage transients.The I/O terminal pins on thecameras are numbered left toright, as shown here.Digital Input Pin 3 Connect to GND to activate, or leave floating (or unconnected) to deactivate.GND Pin 2 GroundAuxiliary DC PowerInput(12VDC min 12W)Pin 1 Connected electrically in parallel with the power adapter, this pin provides anauxiliary connector for mains power to the unit. It can also be used to powerauxiliary equipment, max 50mA.41 2 3ozzoo oo oAXIS 214 PTZ3.3VPowere.g. push buttonDevicez4o3oLinearPowerSupplyo2ooRelayGND+1Fuse 500mA
