IMPORTANT:
• Input and output of the EXT I/O terminal 2 and 3 can be switched by configuring the setting.
"Off" is selected by default. It is possible to determine whether or not to receive input from EXT
I/O terminal 2 and 3 (ALARM IN2, 3) by selecting "Off", "Alarm input", "Alarm output" or "AUX
output" for "Terminal 2" or "Terminal 3" on the [Alarm] tab on the "Alarm" page. Refer to the
Operating Instructions (included in the CD-ROM) for further information.
• When using the EXT I/O terminals as the output terminals, ensure they do not cause signal col-
lision with external signals.
• In order for the EXT I/O terminal to detect alarm inputs when the terminal status is changed
from Open to Close (On) or from Close to Open (Off), about 100 ms or more is needed.
Because alarms cannot be detected for about 5 seconds after a detection is made, alarm
inputs received within about 5 seconds after an alarm is detected are not detected.
v Connect a LAN cable (category 5 or better, straight, STP*) to the network connector.
* For Europe
b Connect the power cable.
• When using 12 V DC power supply*
1
Connect the output cable of the AC adaptor to the 2P power cable.
• When using PoE (IEEE802.3af compliant)
Connect a LAN cable (category 5 or better, straight, STP*
2
) between a PoE device (such as a
hub) and the network connector of the camera.
*1 ONLY CONNECT 12 V DC CLASS 2 POWER SUPPLY (UL 1310/CSA 223) or LIMITED
POWER SOURCE (IEC/EN/UL/CSA 60950-1).
*2 For Europe
IMPORTANT:
• Use all 4 pairs (8 pins) of the LAN cable.
• The maximum cable length is 100 m {328 feet}.
• Make sure that the PoE device in use is compliant with IEEE802.3af standard.
• When connecting both the 12 V DC power supply and the PoE device for power supply,
12 V DC will be used for power supply. Depending on the PoE device used, the power supply
lamp may not light and the network connections may not be possible. In this case, disable the
PoE device setting, and refer to the operating instructions of the PoE device in use.
• When the LAN cable is disconnected once, reconnect the cable after about 2 seconds. When
the cable is quickly reconnected, the power may not be supplied from the PoE device.
