43AXIS 221 - The I/O Units ConnectorsThe I/O Units ConnectorsI/O Terminal ConnectorPinout and InterfaceThe 10-pin I/O terminal connector provides the interface to a solid state relay output, twodigital photo-coupled inputs, RS-485, GND and auxiliary power.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 - used for connecting external alarm devices and triggering images for spe-cific alarm-based events. The input is typically connected to a motion detector orany other external security device, and images can be uploaded whenever thedetector is activated. Maximum 18V DC is allowed on the input.• Output - can drive a maximum load of 50V DC at 100mA directly or heavierloads by connecting additional relay circuitry. If the output is used with an exter-nal relay, a diode must be connected in parallel with the load for protectionagainst any voltage transients.Caution!Connecting AC to the inputs/outputs will damage the unit.terminal10-pin I/Oconnector1 2 3 4 5 6 7 8 9 10connectorPowerblockconnectorPower adaptorconnector (D-sub)RS-232RS-485connector |
