NVT DigitalEQ NV-872 User manual

DigitalEQTM Re eiver Hub Produ t Installation
Manual Models NV-872, NV-1672 and NV-3272
The Digital EQTM Receiver Hub is an active (ampli-
fied) hub that allows the transmission of real-time
monochrome or color video for distances up to one
mile (1,6km) using Category-rated Unshielded
Twisted-Pair (UTP) wire. Note: PAL video does require
the use of Category-5 or better at 1 mile (1,6km). The
receiver hub continuously and automatically compen-
sates for cable attenuation, ground-loops, and wiring
polarity, independent of the video signal image. The
1U high hub is equipped with multi-stage transient
protection.
The NV-872 is an 8-port receiver with four DA out-
puts per channel. The NV-1672 is a 16-port receiver
with two DA outputs per channel. The NV-3272 is a
32-port receiver with one output per channel.
Wire Type
The DigitalEQTM UTP Receiver Hub operates best with
category-rated Unshielded twisted-pair (UTP) wire. It
may also be used with category-rated foiled twisted-
pair (FTP) wire, or with multi-pair wire with an overall
shield (6 or more pairs). Wire gauges of 24 to 16 AWG
(0,5 to 1,3mm) are supported.
Shielded twisted-pair (STP) wire may also be used,
up to a maximum distance of 1,000ft (300m).
The video signal may co-exist in the same wire
bundle as other video, telephone, data, control signals,
or low-voltage power. It is also OK to run NVT signals
near electromagnetic fields (in accordance with
National Electrical Code, and other local safety
requirements.
Do NOT use un-twisted wire. Due to near-end
crosstalk, do not send a transmit and a receive signal
in the same wire bundle. Exception: Up to 1,000ft
(300m); or 2,000ft (600m) Category 5 or better.
Up-the-Coax Pan/Tilt/Zoom telemetry signals are
NOT supported. Use a second wire-pair for RS-422 or
RS- 485 signals instead.
NVT recommends the use of factory-crimped R 45
patch cables rather than unreliable field-crimped R 45s
to connect between the NVT deviceand an adjacent
female R 45 jack.
Wire Distan e
It is recommended that the wire distance be measured
to ensure that it does not exceed 3,000ft (1km), or
1 mile 5,280ft (1,6km) if the transmitter is an NV-653T.
Re ommended Wire Distan e:
All measured distances 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 1,000ft (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 in underground conduit or wet locations must be
polyethylene-jacketed, gel-filled. Wire in plenum envi-
ronments must be plenum-rated, per local codes.
Conne ting the Camera End
Use any NVT passive transceiver, (such as the
NV-214A-M) or qualified OEM camera with built-in UTP
output, or the NV-653T Active Transmitter. Install per the
instructions that come with the transmitting device.
1) Re d these instructions.
2) Keep these instructions.
3) Heed ll w rnings.
4) Follow ll instructions.
5) Do not use this pp r tus ne r w ter.
6) Cle n only with dry cloth.
7) Do not block ny ventil tion openings.
8) Inst ll in ccord nce with the m nuf cturer’s instructions.
9) Do not inst ll ne r ny he t sources such s r di tors,
he t registers, stoves or other pp r tus (including DVRs)
th t produce he t.
10) Do not defe t the s fety purpose of the pol rized or
grounding-type plug. A pol rized plug h s two bl des with
one wider th n the other. A grounding type plug h s two
bl des nd third grounding prong. The wider bl de or the
third prong re provided for your s fety. If the provided plug
does not fit into your outlet, consult n electrici n for repl ce-
ment of the obsolete outlet.
11) Protect the power cord from being w lked on or pinched
p rticul rly t plugs, convenience recept cles, nd the point
where they exit from the pp r tus.
12) Only use tt chments/ ccessories specified by the
m nuf cturer.
13) Use only with c rt, st nd, tripod, br cket, or t ble spec-
ified by the m nuf cturer, or sold with the pp r tus. When
c rt is used, use c ution when moving the c rt/ pp r tus
combin tion to void injury from tipover.
14) Unplug this pp r tus during lightning storms or when
unused for long periods of time.
15) Refer ll servicing to qu lified service personnel. Servic-
ing is required when the pp r tus h s been d m ged in ny
w y, such s power supply cord or plug is d m ged, liquid
h s been spilled, or objects h ve f llen into the pp r tus,
the pp r tus h s been exposed to r in or moisture, does
not oper te norm lly, or h s 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 environ-
ment where the operating ambient temperature exceeds
1220° F (50° C). The ventilation should not be impeded
by covering the ventilation openings with items, such as
newspapers, table-cloths, curtains, etc. No naked flame
sources, such as lighted candles should be placed on
the apparatus.
IMPORTANT SAFETY INSTRUCTIONS
TO REDUCE THE RISK OF ELECTRICAL SHOCK,
DO NOT REMO E CO ER OR BACK. NO USER
SER ICEABLE PARTS INSIDE. REFER SER ICING
TO QUALIFIED SER ICE PERSONNEL.
WARNING: TO REDUCE THE RISK OF ELECTRI-
CAL SHOCK, DO NOT EXPOSE THIS APPARATUS
TO RAIN OR MOISTURE.
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 on 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 the Monitor End
The DigitalEQTMReceiver Hub has R 45 jack input
connections for the video signals, with four signals
grouped onto each R 45 jack.
UTP Pinouts
The NV-872 supports channels 1 through 8. The
NV-1672 supports channels 1 through 16. The NV-3272
supports channels 1 through 32.
If screw-terminal connections are desired, use the
supplied NV-R 45A-to-screw-terminal adaptor acces-
sory. Torque screws to 2in-lb (0,2Nm).
For R 45 connectivity, bring all UTP-based video sig-
nals into a punch-block or R 45 patch panel near the
Hub. NVT recommends the use of factory-crimped R 45
patch cables rather than unreliable field-crimped R 45s
to connect between the block or panel and the Hub.
Inputs are not polarity sensitive, and no adjustments
are required.
Connect the Hub’s outputs to DVRs, Monitors, Matrix
switches, Encoders, etc. as required, using the supplied
2ft (60cm) BNC patch cords.
Verify the proper voltage selector switch setting for the
mains voltage, and connect the power cord to a grounded
outlet.
Upon power-up, the Hub will momentarily display its
revision, and then display its blue Power LED and status
for each channel:
Channel Status LEDs (each channel)
OFF: No signal
GREEN: Valid video received
AMBER: Poor video signal too weak or too strong
due to:
1) wire too long
2) shielded wire
3) water in the wire
4) camera’s output level too high
RED: Signal received but video characteristics not iden-
tifiable. Check for ground loops or 24VAC problems.
Ra k / Wall / Table Mounting
Ambient temperature must be below 122°F (50°C). Air-
flow must be at least 4 ft3/S of un-restricted airflow. Many
DVRs produce enough heat to exceed this temperature
without external airflow.
For rack mounting, attach the supplied mounting
brackets to the Hub chassis using the supplied screws:
Note that the brackets allow installation with the front
or rear facing out.
For wall-mount installations, they may be attached
to the corners of the chassis.
For table-mount installations, attach the four rubber
feet (supplied) to the bottom of the chassis.

Customer Support
If you are experiencing problems, attempt to simplify
your setup. Test each cable segment separately. For ex-
ample, test the camera and monitor together without the
other equipment. Then add in the NVT transceivers back-
to-back. Test each segment of a long cable run independ-
ently. Attempt to isolate the problem.
NVT customer support can be reached 8:00 AM to 5:30
PM Monday through Friday.
