UTP Video Transmitter +12VDC Converter
Model NV-226J-PV Installation Manual
1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this apparatus near water.
6) Clean only with a dry cloth.
7) Do not block any ventilation openings.
8) Install in accordance with the manufacturer’s instructions.
9) Do not install near any heat sources such as radiators, heat reg-
isters, stoves or other apparatus (including D Rs) that produce
heat.
10) Do not defeat the safety purpose of the polarized or grounding-
type plug. A polarized plug has two blades with one wider than the
other. A grounding type plug has two blades and a third grounding
prong. The wider blade or the third prong are provided for your safe-
ty. If the provided plug does not fit into your outlet, consult an elec-
trician for replacement of the obsolete outlet.
11) Protect the power cord from being walked on or pinched partic-
ularly at plugs, convenience receptacles, and the point where they
exit from the apparatus.
12) Only use attachments/accessories specified by the manufacturer.
13) Use only with cart, stand, tripod, bracket, or table specified by
the manufacturer, or sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus combination to avoid
injury from tipover.
14) Unplug this apparatus during lightning storms or when unused
for long periods of time.
15) Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way, such
as a power supply cord or plug is damaged, liquid has been spilled,
or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has been
dropped.
This installation should be made by a qualified service
person and should conform to all local codes.
WARNING - Do not install the unit in an environment
where the operating ambient temperature exceeds
167° F (75° C). The ventilation should not be impeded by
TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO
NOT REMOVE COVER OR BACK. NO USER SERV-
ICEABLE PARTS INSIDE. REFER SERVICING TO
QUALIFIED SERVICE PERSONNEL.
WARNING: TO REDUCE THE RISK OF ELECTRICAL
SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN
OR MOISTURE.
IMPORTANT SAFETY INSTRUCTIONS
The NVT UTP Video Transmitter +12VDC
Converter combines a passive video transmitter
with a 24VAC-to-12VDC switching power supply.
When used with an NVT Power Supply Cable
Integrator, cameras may be located at substan-
tial distances, yet powered from the control
room. Unlike conventional CCTV installations or
power-over-ethernet IP-based video, this archi-
tecture requires no intermediate equipment in
closets, and allows the entire system to be pow-
ered by a single control-room resident uninter-
ruptible power supply, if required.
Designed as part of NVT’s PVD™ system, the
NV-226J-PV UTP Video Transmitter +12VDC
Converter supports fixed 12VDC cameras that
draw up to 400 mA (4.8 Watts) using standard 4-
pair RJ45 EIA/TIA 568B compliant premises
wiring and pinouts.
Wire Type
The PVD system operates well with Category
Unshielded Twisted-Pair (UTP) wire, 24-22 AWG
(0,5-0,6mm). NVT signals may reside near elec-
tromagnetic fields (in accordance with National
Electrical Code, and other local safety require-
ments.)
Low voltage camera power video may be sent
within same wire bundle.
Do NOT use shielded twisted-pair wire unless it
is Category rated. Multi-pair wire with an overall
shield (6 or more pairs) is O .
Do NOT use un-twisted wire.
Wire in underground conduit or wet locations
must be polyethylene-jacketed, gel-filled.
Do not run 24/28 VAC within same wire bundle
with telecom or other datacom signals.
NVT recommends the use of factory-crimped
RJ45 patch cables rather than unreliable field-
crimped RJ45s to connect between the NVT
device and an adjacent female RJ45 jack.
Wire Distan e
It is recommended that the wire distance be
measured to ensure that it does not exceed the
maximum allowable distance. All measured dis-
tances include any coax in the path.
Wire resistance may be measured with an ohm-
meter by shorting the two conductors together at
the far end, and measuring the loop-resistance
out and back
Loop Resistan e per 1000ft (300m)
24 AWG (0,53 mm) = 52 ohms
23 AWG (0,57 mm) = 42 ohms
22 AWG (0,64 mm) = 33 ohms
20 AWG (0,81 mm) = 21 ohms
19 AWG (0,91 mm) = 16 ohms
18 AWG (1,02 mm) = 13 ohms
Wire distances are limited as shown in the Wire
Distance Guide on back page.
covering the ventilation openings with items, such as news-
papers, table-cloths, curtains, etc. No naked flame
sources, such as lighted candles should be placed on the
apparatus.
WARNING - Do not interconnect multiple
outputs.
WARNING - The apparatus shall not be exposed
to dripping or splashing and no objects filled with liquids,
such as vases, shall be placed o the apparatus.
WARNING - Use only a Certified power cord and
plug (coupler / mains) assemblies for location
installed.
WARNING - Power cord is regarded as main
disconnect.
WARNING - The appliance coupler (power
cord/mains) shall remain readily operable.
WARNING - For safety, never put N T signals in
the same conduit as high-voltage wiring.
WARNING - Do not restrict airflow around any
active powered N T products.

Conne ting NV-226J-PV at Camera End
Connect the black power conductor to the
camera’s negative power terminal. Connect the
red lead to the camera’s +12VDC power terminal.
Then connect the Male BNC to the camera’s video
output.
Connect a factory-crimped RJ45 patch cable
(rather than unreliable field-crimped RJ45s)
between the NV-226J-PV and an adjacent female
RJ45 jack. Straight-through wiring pinouts are:
Conne ting PVD at the Power Supply
Cable Integrator
Bring the 4-pair PVD cable from each camera back
to the location of the Power Supply Cable Integrator.
NVT recommends that an RJ45 Patch Panel be used
here in conjunction with RJ45 patch-cords. Use of
these EIA/TIA 568B compliant practices allows for
easy testing with an RJ45 (LAN) tester, as well as
moves and changes.
The Power Supply Cable Integrator may be one of:
NV-216A-PV or NV-218A-PVD single channel
device.
NV-704J-PVD or NV-716J-PVD in conjunction
with a multi-output power supply with individually
floating outputs. Most conventional multi-output
power supplies employ a bus architecture which is
unsuitable for this application.
NV-4PS10-PVD or NV-16PS10-PVD in conjunc-
tion with a passive or active receiver hub, such as
the NV-413, NV-813(S), NV-1613(S), NV-3213(S),
NV-442, NV-452R, NV-842, NV-1642, NV-3242, NV-
872, NV-1672 or NV-3272.
NV-4PS13-PVD, NV-8PS13-PVD, NV-16PS13-
PVD, NV-8PS42-PVD, NV-16PS42-PVD, or
NV-32PS42-PVD

tion manual for the selected receive-end equipment.

Agen y
The NV-226J-PV is listed and/or conforms to the
following certifications and directives:
UL listed to UL2044 or UL/IEC60065 cUL Listed to
CAN/CSA22.2 No.1 for Canada CE mark under
EMC and low voltage directives for the European
Union. Complies with FCC part 15B limits
Troubleshooting
If you are experiencing problems, check the RJ45
pinouts. Check with an RJ45 tester. NVT recom-
mends factory crimped RJ45 cables. Avoid field
crimping. Test each segment of a long cable run
independently. Attempt to isolate the problem.
Attempt to simplify your setup. View the camera’s
video output locally. Measure AC and DC voltages.
Power the camera locally.
