Wireless LAN
DWL-P200
Key Features
Power Over Ethernet Adapter
The DWL-P200 Power Over Ethernet (PoE) adapter is designed to supply operational power to surveillance cameras and
wireless LAN devices such as access points, bridges and routers. It enable power current to travel on the Ethernet network
cable, thus eliminates the need to directly connect a power supply to the wireless LAN device. The DWL-P200 supports both
5VDC and 12VDC power requirements. Power requirement can be selected through a DIP switch.
Facilitates Installation
Data and DC Power Transmission on the Same
Network Cable
The Power Over Ethernet allows you to install the wireless
LAN device and surveillance camera at places such as on a
building rooftop, on or near a ceiling, or other difficult places
where power is not easily accessible. The idea is increase the
usefulness of your camera and wireless LAN to provide
connectivity to users regardless of their proximity to a power
outlet or a network cable.
On a standard UTP Category 5 cable, only two pairs (pins 1,
2, 3 and 6) are used for Ethernet data transfer. Power Over
Ethernet is designed to take advantage of the unused pins of
the remaining pair of cable wires. Consequently, a single
Category 5 cable will now carry both Ethernet data and
DC power. The idea is to supply the remote end with
power and the requirements of Ethernet connectivity via a
single Cat 5 cable.
The DWL-P200 includes a base unit and a terminal unit.
At one end, the base unit inserts DC voltage into the
unused wires (pins 4, 5, 7 and 8) of the network cable. At
the other end, the terminal unit splits the data and DC
power apart. Data signals continue to travel on remaining
network cables, while DC power is fed into the power
adapter, which connects to an AC power outlet.
