1 Preface
This product is a coaxial - LAN converter consisting of the receiver side unit and the
camera side unit. It is capable of implementing long distance, high speed digital data
transmission on existing coaxial cables with low setup costs. With the built-in PoE
function, the unit is able to supply power to the network cameras, which eliminates the
need for installing power outlets for the cameras.

1.1 Main Features
Up to 4 network cameras can be connected and used on a single receiver side unit*1.
Now we have a true space-saving system.
Power over Ethernet Plus (PoE+) ready
The coaxial - LAN converter is compliant with PoE+ standards (IEEE802.3at) and
PoE+ cameras can be connected and used*1.
Use over long distances
PR201
The coaxial - LAN converter can be used for distances of up to 300 m (984 feet) for
connections for recommended PoE+ cameras and 500 m (1,640 feet) for connections
for recommended PoE cameras and 2.0 km (6,560 feet) for connections for cameras
using an external power supply*1. (When used with RG-6/U coaxial cable, and the loop
resistance is below 4 W/100 m {328 feet} without additional joint parts.)
High-speed transmission
The coaxial - LAN converter is capable of transmission speeds of 35 Mbps or over for
TCP*2, and 45 Mbps or over for UDP connections.*2 (When used with RG-6/U coaxial
cable, and for distances under 2.0 km (6,560 feet)
PR201
, 500 m (1,640 feet)
PR204
).
No setup required
Connections can be established by simply connecting the coaxial cable to the coaxial
- LAN converter.
*1 There are limitations on the combinations of the cameras to be connected, the type of power supply and
transmission range to the receiver side units. Please see page 31 for details. For information on
recommended network cameras, see our support site
(https://i-pro.com/global/en/surveillance/training_support/support/technical_information).
*2 Transmission speed is the speed of transmission between the receiver side unit and the camera side unit.
Values may vary depending on the condition of the coaxial cable (for example, as the cable deteriorates over
time), network conditions, etc.

4. Precautions before receiver installations
PR204
PR201
• When mounting 3 to 4 connected receiver side units to the rack, use the following
bracket (locally procured).
– Rack mount bracket:
For WJ-PR204/WJ-PR201: BY-HCA10A
For WJ-PR204E/WJ-PR201E: BY-HCA10CE
• Available racks
– EIA standard rack or equivalent (third party)
EIA19 type
• Rack mounting screws
– M5 ´ 12 mm {15/32 inches} screws
5. Precautions before camera installations
PC200
• Use the screws with the specifications shown on page 26 when mounting the
camera side unit to a ceiling or wall. Screws are included with camera side unit.
Use screws that are appropriate for the material of the ceiling or wall.
• When mounting the camera side unit to a ceiling or wall (see page 26), do not
drive the screws into a soft material. Drive the screws into a secure, 25 mm
(1 inch) thick area of the ceiling or wall, such as a crossbeam, otherwise the
camera side unit may fall. If there is no crossbeam, place a board on the other
side of the ceiling or wall to make sure the camera side unit is securely mounted.
• When mounting a camera side unit on a concrete or mortar ceiling or wall, use
a drill and anchors (locally procured, body diameter 4 mm {3/16 inches}) and
make holes using the following procedure.
i. Mark points where you are going to make holes (2 places) according to the
position of the camera side unit.
ii. Make holes in the areas that you marked with an electric drill.
• Mortar ceilings break easily when drilling. Be careful of pieces of mortar
which may become loose and fall.
iii. Insert the anchors (locally procured) into the holes and push them inside with
a hammer.
Caulk to waterproof
Drill for concrete (in case of tile, use a drill for tile)
• Mount the camera side unit to a secure area and make sure that the anchors and
screws are secured.

6. Screw tightening
• The screws and bolts must be tightened with an appropriate tightening torque
according to the material and strength of the installation area.
• Do not use an impact driver. Use of an impact driver may damage the screws or
cause tightening excessively.
• When a screw is tightened, make the screw at a right angle to the surface. After
tightening the screws or bolts, perform checks to ensure that the tightening is
sufficient enough so that there is no movement or looseness.
7. Coaxial cable connections
• Disconnect the coaxial cable from all devices and measure the insulation
resistance of the coaxial cable (new or existing) before making connections.
Insulation resistance value: 1 MW or more for DC 500 V
• Confirm the length of the coaxial cable (see page 31, page 33).
• We recommend RG-6/U coaxial cable.
• The performance of the coaxial cable may be affected if it is relayed.
• Use only the following recommended BNC plug when connecting coaxial cables
to the BNC connectors of the unit.
– Applicable plug: MIL-C39012C, MIL-C39012/16F, or BS CECC2212: 1981
(Suffixes attached to the standards may be updated.)
BNC plug
(locally procured)
Coaxial cable
(locally procured)
– Tip dimensions inside the recommended BNC plug
Diameter: 1.32 mm (0.052 inches) to
1.37 mm (0.054 inches)
Diameter: 0.13 mm (0.005 inches) to
0.69 mm (0.027 inches)
IMPORTANT
• Use a suitable plug. Using a non-specified plug may cause a bad
connection or cause damage to the BNC connector.

8. Mounting and connections
• Do not mount camera side units above or below other camera side units. This
can cause transmission interference. When mounting several camera side units
in the same area, mount them side by side each other.
• When connecting the coaxial cable to the unit, make sure that no other devices
are connected to the coaxial cable. Connecting the coaxial cable to the unit when
there are other devices connected (such as an analog CCTV camera), may
cause damage to the connected device.
• When another device such as lightning arresters is connected to the coaxial
cable, it may give impact to transmission quality. Do not connect other devices
to the coaxial cable.
• When mounting extra cameras or removing cameras, make sure to turn off the
power from the receiver side before starting work and the turn on the power once
the work has been completed.
• When the receiver side is connected to a PoE hub as well as an AC adaptor, the
power will not be turned off even if you disconnect the AC adaptor. In this case,
make sure to disconnect the Ethernet cable to turn off the power.
9. Sulfurization caused by rubber products
Do not store or install any rubber products (such as gaskets or rubber feet) that
contain sulfur near or in the same container as this product. Sulfuric compounds in
the rubber product may cause sulfuric corrosion of this product’s electrical
components or terminals, leading to malfunction.
10. Shielded (STP) LAN cables must be used with this unit to ensure compliance
with CE standards. (WJ-PR204E/WJ-PR201E/WJ-PC200E)
11. Make sure to remove this product if it will no longer be used.
