The maximum cable length is 100 m {328 feet}. Make sure that the PoE device in use is compliant with IEEE802.3af standard. When the Ethernet cable is disconnected once, reconnect the cable after around 2 seconds.When the cable is quickly reconnected, the power may not be supplied from the PoE device.* This illustration represents WV-X8570NThis cable isprovided only withWV-X8570N.DUSB terminal(for installationconstructor)BAlarm I/O cable / 4P alarm cable (accessory) X 8570Note: Off, input, and output of the external I/O terminal 2 and 3 can be switched by configuring thesetting. Refer to the Operating Instructions on the Panasonic support web site for further infor-mation about the external I/O terminal 2 and 3 (ALARM IN2, 3) settings ("Off", "Alarm input","Alarm output" or "AUX output").Connect the 4P alarm cable (accessory) to the alarm I/O cable, and connect the external devicecable to the 4P alarm cable.
