26v Connect external devices to the EXT I/O terminal.When connecting an external device, remove 9 mm - 10 mm{11/32 inches - 13/32 inches} of the outer jacket of the cableand twist the cable core to prevent the short circuit first.Specification of cable (wire): 22 AWG - 28 AWGSingle core, twisted• Check whether the stripped part of the wire is not exposed and is securely connected.4 3 2 1r GNDe AUX OUTw ALARM OUTq ALARM INIMPORTANT:• Do not connect 2 wires or more directly to a terminal. When it is necessary to connect 2 or morewires, use a splitter.• Input and output of the EXT I/O terminal 2 and 3 can be switched by configuring the setting. "Off" isselected by default. It is possible to determine whether or not to receive input from EXT I/O terminal 2and 3 (ALARM IN2, 3) by selecting "Off", "Alarm input", "Alarm output" or "AUX output" for "Terminal2" or "Terminal 3" on the [Alarm] tab on the "Alarm" page. Refer to the Operating Instructions (includ-ed in the CD-ROM) for further information.• Connect an external device with verifying that the ratings are within the specifications above.• When using the EXT I/O terminals as the output terminals, ensure they do not cause signal collisionwith external signals.• ALARM OUT, AUX OUTOutput specification: Open collector output (maximum applied voltage: 20 V DC)Open: 4 V - 5 V DC by internal pull-upClose: Output voltage 1 V DC or less (50 mA or less)• ALARM IN / DAY/NIGHT IN*Input specification: No-voltage make contact input (4 V - 5 V DC, internally pulled up)OFF: Open or 4 V - 5 V DCON: Make contact with GND (required drive current: 1 mA or more)* DAY/NIGHT IN is only for WV-SP509.b Connect a LAN cable (category 5 or better,STP*) to the network connector on the rear ofthe camera.* For EuropeStrip range9 mm - 10 mm{11/32 inches - 13/32 inches}4 3 2 1r GNDe ALARM IN3 / AUX OUTw ALARM IN2 / ALARM OUTq ALARM IN1 / DAY/NIGHT INPOWER10BASE T/100BASE-TXAUDIO OUT MIC/LINE INEXT I/OSD CARD/ABFMONITOR OUTACT LINK12V = INGND 4 3 2 1INITIALSETALARM IN 1/DAY/NIGHT INALARM IN 3/AUX OUT ALARM IN 2/ALARM OUT(This illustration representsWV-SP509.)LAN cable
