Installation Guide

Wiring Tech Notes
1. Do use point-to-point Unshielded Twisted Pair wire, 24-16 AWG
(0,5-1,5mm), stranded or solid, Category 5 or better.
2. 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 video signals in or near electromagnetic fields (in accordance
with National Electrical Code, local, or other local safety
requirements).
3. Measure the wire distance.
4. DO NOT USE individually shielded twisted pair. Overall shielded, multi-
pair (6pr +) Cat5 is OK.
5. DO NOT USE UN-TWISTED WIRE.
6. Due to near-end crosstalk, don’t send a transmit and a receive signal
in the same wire bundle. Exceptions: Category 5 or better cable, up
to 2,000 ft (600m) are OK.
7. Don’t send “Up-the-Coax” Pan/Tilt/Zoom signals through active
(amplified) NVT transceivers. Passive NVT transceivers will transmit
“up the coax” P/T/Z control signals up to 750ft (225m)
Measure Your Wire Distance
Note: All NVT quoted distance specifications include any coax in the run.
It is recommended that the wire distance be measured to ensure that the
capability of the NVT product is correct.
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.
Table 1 Resistance 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
Connecting the Camera End
1. If the transmitter is a model NV-653T, connect power, as specified in
the “Power Supply Requirements.” The blue “Power” LED should light.
2. Connect the baseband video signal from the camera to the BNC on
the transmitter using a 75Ω coax cable with BNC connector. The
NV-208A-M, NV-213A-M, and NV-214A-M can be connected directly
to the camera.
3. If the transmitter is a model NV-653T, the green “Active” LED should
have a steady light, indicating that video signal is present. Set the
three-position distance switch to the correct distance for your wire run.
4. Connect the UTP output of the transmitter to existing or new
unshielded twisted pair wiring by attaching each conductor of a
twisted pair of wires to each screw or screwless terminal. Torque to
5 in-lbs (200 or 600 series) or 2 in-lbs (400 series or hubs). Note
wire colors so that polarity may be observed at the receiving end.
5. If the passive video transceiver hub is a model
NV-813, NV-813S, NV-1613, NV-1613S, NV-3213 or NV-3213S,
connect the UTP wire using the 8-pin RJ45 connector as shown in
the wiring diagram below.
6. Optional: When using the model NV-413A, either connect UTP wire to
terminal block as described in #4 above, or connect UTP wire using
8-pin RJ45 connector as shown in wiring diagram. Do not do both.
7. If the transmitter is a model NV-813, NV-1613 or the
NV-3213 connect the ground screw to a solid earth ground. If the
transmitter is a model NV-653T, connect the NVT ground screw to the
camera’s ground, but do not connect either to earth ground. An
electrically floating camera will maintain protection from damaging
transients while making it less of a target to lightning strikes. See
recommended grounding diagram. For safety, always follow the
camera manufacturer’s grounding requirements; they take
precedence.
8. If you are using a camera which has an NVT qualified built-in
unshielded twisted pair module, you will be able to connect the
camera’s output directly to your UTP wiring. If you have any questions
on this connection, please refer to your camera installation manual,
or call the camera manufacturer or NVT.
Connecting the Monitor End
1. If the receiver is a model NV-452R, NV-652R, NV-842, NV-1642,
NV-3242, NV-872, NV-1672 or NV-3272, connect power, as specified
in the “Power Supply Requirements.” The blue “Power” LED should
light.
2. If the receiver is a model NV-452R, NV-652R, NV-813, NV-1613, or
the NV-3213, connect the ground screw to the same earth ground as
the rest of receive-end equipment.
3. Connect the UTP input of the receiver to existing or new UTP wiring
by attaching each conductor of a twisted pair of wires to each screw
or screwless terminal. Torque to 5 in-lbs (200 or 600 series) or 2
in-lbs (400 series or hubs).
If the receiver is a model NV-452R, NV-652R, NV-842, NV-1642,
NV-3242, NV-872, NV-1672, or NV-3272, the green “Active” LED
should have a steady light, indicating that video is present. A
flickering light typically means that there is something wrong with the
cabling.
4. When using the model NV-452R, either connect UTP wire to terminal
block as described in #3 above, or connect UTP wire using 8-pin
RJ45 connector as shown in wiring diagram. Do not do both.
5. If using a receiver model NV-813(S), NV-842, NV-872,
NV-1613(S), NV-1642, NV-1672, NV-3213(S), NV-3242 or NV-3272,
connect UTP wire using 8-pin RJ45 connectors as shown in wiring
diagram.
6. Connect the baseband video signal from the receiver to the video
monitor (or other video equipment, multiplexer, quad, etc.) using a
75Ω coax cable with a BNC connector, or directly to video equipment
if using the NV-208A-M or NV-214A-M.
7. Confirm that your monitor or other receiving equipment is correctly
terminated with a single 75Ω terminator.
8. For best pictures using the NV-452R or NV-652R, adjust the distance
equalization controls.
Turn both controls to their minimum counter-clockwise position.
Next, turn brightness/LF control clockwise until desired degree of
brightness is achieved. Then turn sharpness/HF control until picture
is crisp and clear, but not “grainy.”
Rack Mounting
Up to ten NV-652Rs or two NV-413As or NV-452Rs may be rack mounted
on the NV-RM8/10. The Hub models NV-813(S), NV-842,
NV-1613(S), NV-1642, NV-3213(S), NV-3242, NV-872, NV-1672, or
NV-3272 are rack mountable and come complete with mounting
brackets and screws.
Rack Mounting NVT Hubs
Do not restrict airflow around any active powered NVT product.
Follow these instructions to mount the NV-813(S), NV-842, NV-872,
NV-1613(S), NV-1642, NV-1672, NV-3213(S), NV-3242, or NV-3272
Hub models in a rack or cabinet.
1. Attach the mounting brackets to the Hub chassis with supplied screws.
Note that the Hub’s mounting brackets allow you to rack mount or
wall mount each Hub with either the top front or rear facing out.
2. Position the Hub in the rack or cabinet and slide it up or down until
the rack holes line up with the bracket holes. Then attach the Hub to
the rack with the supplied screws.
Table Mounting the Hubs
Attach the self-adhesive rubber feet to the bottom of the Hub.

powered by a safety extra low voltage (SELV) power source that
delivers less than 60VAC or DC under single fault conditions.
Additionally, a limited power source with less than 5A total available
current should be used, such as a pre-approved wall-mount or
desktop power supply that has been evaluated by a product safety
agency such as UL or TUV Rheinland, in the country of end-use.
Note: NV-452R, NV-652R and the NV-653T all require floating power
supplies.

transceivers, back-to-back. Test each segment of a long cable-run
independently. Attempt to isolate the problem.
