IMPORTANT SAFETY INSTRUCTIONS

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 registers, stoves or other apparatus (including DVRs)
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 safety. If the provided plug
does not fit into your outlet, consult an electrician for replace-
ment of the obsolete outlet.
11) Protect the power cord from being walked on or pinched
particularly 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 spec-
ified 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. Servic-
ing 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.
TO REDUCE THE RISK OF ELECTRICAL SHOCK,
DO NOT REMOVE COVER OR BACK. NO USER
SERVICEABLE PARTS INSIDE. REFER SERVICING
TO QUALIFIED SERVICE PERSONNEL.
WARNING: TO REDUCE THE RISK OF ELECTRI-
CAL SHOCK, DO NOT EXPOSE THIS APPARATUS
TO RAIN OR MOISTURE.
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
120° 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.
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 NVT signals in
the same conduit as high-voltage wiring.
WARNING - Do not restrict airflow around any
active powered NVT products.
TM
The StubEQ Receiver Hub is an active (amplified)
hub that allows the transmission of real-time mono-
chrome or color video for distances up to 1,500ft
(460m), (2,000ft (600m) if the transmitter is a
NV-653T). using Category-2 or better Unshielded
Twisted-Pair (UTP) wire. The receiver hub continuously
and automatically compensates for cable attenuation,
and ground-loops, independent of the video signal
image. The 1U high hub is equipped with multi-stage
transient protection.

Wire Type

TM
The StubEQ 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.
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 Na-
tional Electrical Code, and other local safety require-
ments.
Do NOT use shielded twisted-pair wire unless it is
Category rated. Multi-pair wire with an overall shield
(6 or more pairs) is OK.
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 1,500ft (460m) 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 RJ45
patch cables rather than unreliable field-crimped
RJ45s to connect between the NVT device and an ad-
jacent female RJ45 jack.

Wire Distance

It is recommended that the wire distance be measured
to ensure that it does not exceed 1,500ft (460m), 2,000ft
(600m) if the transmitter is a NV-653T).
Recommended Wire Distance:
Cat 5 Wire Distance
780
700
630
550
475
400
315
235
Cat 5 Wire Distance
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 Resistance per 1,000ft (300m)

24 AWG (0,53 mm) =
23 AWG (0,57 mm) =
22 AWG (0,64 mm) =
20 AWG (0,81 mm) =
19 AWG (0,91 mm) =
18 AWG (1,02 mm) =
Wire in underground conduit or wet locations must be
polyethylene-jacketed, gel-filled. Wire in plenum environ-
ments must be plenum-rated, per local codes.

Connecting 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.

Connecting the Monitor End

The StubEQ Receiver Hub has RJ45 jack input
connections for the video signals, with four signals
grouped onto each RJ45 jack.
