When using 12 V DC power supply
q
Loosen the screw of the power cord plug
(accessory).
w
Connect the cable of the 12 V DC power
supply to the power cord plug.
Strip the end of the wire by 3 mm to 7 mm
{1/8" to 9/32"}, and twist the stripped part
of the wire sufficiently to avoid short circuit.
Specification of cable (wire): 16 AWG - 28
AWG, single core, twisted
* Check whether the stripped part of the
wire is not exposed and is securely con-
nected
e
Tighten the screw of the power cord plug.
r
Connect the power cord plug to the 12 V
DC power supply terminal on the rear of
the unit.
t
Hold the power cable using the cable
clamp.
Important:
• Be sure to use the power cord plug provid-
ed with this product.
• Be sure to fully insert the power cord plug
(accessory) into the 12 V DC power supply
terminal. Otherwise, it may damage the
unit or cause malfunction.

Cable clamp
When using PoE (IEEE802.3af compliant)
Connect a LAN cable (category 5 or better) between a PoE device (such as a hub) and the network
connector of the unit.
Important:
• Use all 4 pairs (8 pins) of the LAN cable.
• The maximum cable length is 100 m {328.08'}.
• 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, PoE
will be used for power supply.
• When disconnecting the LAN cable once, reconnect the cable after about 2 seconds.
When the cable is quickly connected, the power may not be supplied from the PoE device.
