The NVT Model NV-EC1701 Ethernet over Coax EoC Transceiver is a compact media converter
that allows 10/100 BaseT Ethernet and PoE+ power to be transmitted using coax cable. These devices
are often used in legacy installations where existing cable is re-deployed as part of an upgrade to IP
cameras. 48 or 56 VDC class 2 power is delivered to one transceiver, which distributes it to up to four
remote transceivers, and their PoE or PoE+ or High Power PoE cameras*.
These transceivers are extremely simple to use, with no IP or MAC addressing required. Status LEDs
indicate power and link connectivity/activity for RJ45 and BNC ports. They are backed by NVT’s award
winning customer support and limited lifetime warranty.
*Distance and number of devices supported will often be lower due to power delivery voltage-drop on the wire. See Wire Distance Chart on pages 8 & 9.

CONFIGURATION INSTRUCTIONS
NV- C1701 oC transceivers transmit high bandwidth encrypted thernet signals over conventional coax cables. To provide utmost signal integrity and security, the
NV- C1701 transceivers must be configured to communicate exclusively with other transceivers within their Network Group. This group typically consists of one
NV- C1701 located at the control room (usually connected to an ethernet switch or router), and up to four remote NV- C1701 transceivers (usually connected to IP cameras).
Before connecting to the network, each NV-EC1701 must learn which other NV-EC1701 transceivers are to be part of that group. This simple process is
called Joining. It is recommended that transceivers in each Network Group be configured prior to deployment using these instructions:
Step One: Gather Materials
• NV- C1701 transceivers
• 48VDC power supply & line-cord (NV-PS48-60W)
• Coax jumper
• Small paper-clip, partially straightened
• Device labels
• IP Network Documentation Log
Step Two: Connect Hardware
• Remove and discard the “Configure Before Use” labels.
• Connect two NV- C1701 transceivers using a coax jumper.
• Connect a 48-56V power supply to transceiver #1; Apply power.
• Verify that the blue POW R L D on each transceiver illuminates.
• After 20 seconds, verify that the green BNC L D on each transceiver is off. If a BNC L D is on, the
transceiver has been previously joined. Perform the un-joining process below before proceeding.
Step Three: Joining
• On transceiver #1, using the straightened paper-clip, momentarily depress the small push-button
located behind and slightly above the RJ45 L D. The blue Power L D will begin blinking.
• Depress the same push-button on the transceiver #2.
• Both transceivers have now entered Join Mode.They will find each other and establish encrypted
communication. In about 10 seconds, the blue Power L Ds on both transceivers will return to a steady
on condition, indicating a successful Join.
Step Four: Adding Transceivers (if required)
• Disconnect transceiver #2 and replace it with a new un-joined transceiver (#3, or #4, or #5).
• Repeat steps two and three to add additional transceivers to the same Network Group.
Step Five: Documentation
• Label the configured transceivers with a unique Network Group ID of your choice.
This will help you identify them after they have been deployed.
• Record this Network Group information in your IP Network Documentation Log.
This log may include essential documentation which will help you identify all
system devices during and after deployment:
• Camera Number • Camera-end NVT Transceiver MAC Address
• Camera Position/Location • NVT Transceiver Network Group Name
• Camera Make & Model • Control Room NVT Transceiver MAC Address
• Camera MAC & IP Address • Control Room Router Port Number
• Camera Login & Password
Un-Joining a Transceiver
If you need to move a transceiver from one Network Group to another, it must first un-learn its previous
Network Group and be returned to an un-joined state. Do this by:
• Connect a 48-56 VDC power supply to a transceiver to be un-joined.
• Wait until its green BNC L D is lit.
• Using the straightened paper-clip, momentarily depress the small push-button located behind
and slightly above the RJ45 L D until the green BNC L D goes off. The RJ45 L D should remain off.
• Release the paperclip.
• Observe that the BNC and RJ45 L Ds flash.
• Observe that the BNC and RJ45 L Ds turn off.
• Observe that the BNC goes on solid.
• Un-joining is now complete.
If you are not sure that un-joining has been successful, remove and then re-apply power, and repeat.

Most installations that use the NV- C1701 transceiver involve
the replacement of an analog camera with an IP camera, while
reusing the installed coax cable. Since most IP cameras support
Po (Power over thernet), the legacy 24VAC distribution may no
longer be needed.
Disconnect all analog equipment from the coax before
installing the IP equipment. The NV- C1701 uses the coax
to deliver 48 or 56VDC. To prevent damage, never connect
analog cameras or analog control-room equipment to an
NV- C1701.
Transceiver Configuration
NVT oC transceivers m st be config red to communicate
exclusively with other transceivers within their Network Gro p.
The configuration process is described on page 3.
Connecting the Camera End
Install the new IP camera. Mount the NV- C1701 nearby.
Connect an RJ45 patch cable between the network connector
(Po ) of the camera and the RJ45 jack on the NV- C1701.
Connect the coax to the BNC jack on the NV- C1701.
For most installations, the IP camera power will be low enough,
and the coax distance short enough, so that the IP camera and
its NV- C1701 can receive power through the coax. In most
cases, a power supply will not be needed at this end. For addi-
tional details, see “High Power xtended Distance
Considerations” on page 7.
Connecting the Control-room End
Install a second NV- C1701 at the control-room end of the coax
cable.
If rack-mounting is desired, use the NV-RM C16 tray, which
supports up to four NV- C1701 transceivers, which together can
support up to 16 cameras.
Connect the coax cable to the BNC jack on the NV- C1701.
Connect a class 2 (S LV) 48V or 56VDC power supply to the
power jack on the NV- C1701. This will provide power to the
entire system, including the cameras. The Blue “Power” L Ds
will illuminate on both transceivers.
Connect an RJ45 patch-cord between the RJ45 jack on the
NV- C1701 and either: 1) an IP camera video input on a Hybrid
DVR, or 2) an thernet switch allocated for video. See “Hybrid
DVR Considerations” on page 5, or “NVR Considerations” on
page 6.
The Green L Ds will illuminate when a network link is estab-
lished, and will blink when data traffic is present.
The NV- C1701 communicates via the coax using
a bus-architecture. This means that up to four
remote camera-end NV- C1701s may be
connected together to a fifth NV- C1701 at the
control-room. The coax cables are connected
together using BNC splitters, available from NVT,
or elsewhere. If you purchase BNC “T” connectors
from another supplier, please purchase high
quality connectors. Low cost connectors have
been found to have intermittent shield connections.
Multiple IP cameras draw more current. To ensure
adequate power, see “High Power xtended
Distance Considerations” on page 7.
The NV- C1701 transceiver has been recently updated to
support full Po , Po +, or High-Power cameras, as well as non-
powered legacy devices.
Unlike conventional Po , voltage-drop and load current must be
confirmed by the installer. See “High Power xtended Distance
Considerations” on page 7.
NVT’s Class 2 current limiting ensures safety of the installation
during fault conditions, while delivering higher power (up to 90
watts) with more efficient allocation amongst loads. Up to two
power s pplies may be sed within a network gro p.

The NV- C1701 transceivers provide transparent end-to-end 10-
baseT or 100-BaseT connectivity with auto detection and auto-
crossover. This means that IP cameras or other devices may be
installed at one end, and their data is transparently delivered to
the other end. Before installing, transceivers must be configured
per the instructions on page 3.
Long coax distances are supported, although local power may be
required for extended distances. See pages 7 - 9.
The NV- C1701 supports TCP/IP, UDP, HTTP, Multi-cast, and other
standard protocols. This allows for the transmission of other
network traffic besides streaming video.
The NV- C1701 is network transparent, and operates in virtually
every network environment, including support for Hybrid DVRs.
These DVRs have some BNC ports for analog cameras, and some
RJ45 ports for IP cameras. The RJ45 “video in” port is the con-
nection point for the NV- C1701. See figure 2.
By deploying a Hybrid DVR, with its dedicated IP camera port(s),
the network is robust and secure, with none of the traffic, hack-
ing, or virus vulnerabilities associated with PC-like hardware on
an open LAN.
Depending on the Hybrid DVR, more than one camera may be
connected to its IP camera port. Check the Hybrid DVR manual for
details.

with PoE, PoE+, or High Power PoE
The NV- C1701 transceivers provide transparent end-to-end 10-baseT
or 100-BaseT connectivity with auto detection and auto-crossover. This
means that IP cameras or other devices may be installed at one end,
and their data is transparently delivered to the other end. Please read
configuration instructions on page 3 before installing.
Long coax distances are supported, although local power may be
required for extended distances. See pages 7 - 9.
The NV- C1701 supports TCP/IP, UDP, HTTP, Multi-cast, and other stan-
dard protocols. This allows for the transmission of other network traffic
besides streaming video.
For IP-based CCTV applications, there are some network configurations
that are robust, and others that are not recommended. In general, it
is best to deploy a separate LAN exclusively for video traffic.
Although it is possible to place IP cameras onto the end-user’s
“ nterprise LAN”, there are several disadvantages in doing so. These
include:
Traffic Management Considerations
When sharing the resources of a LAN, the nature of the traffic must
be well understood for it to operate efficiently. For most end-users,
the business use of their LAN is constantly changing, critical for their
day-to-day operations, and not managed by the same group that
manages their security. IP video can often consume large amounts of
bandwidth, which may or may not be compatible with existing IT traffic.
Security Considerations
Most surveillance systems are installed specifically to protect against
breaches in security. A shared LAN provides potential opportunities
for unauthorized access to security assets. Sniffing IP addresses can
result in the unintended disclosure of IP cameras or network vulner-
abilities. Spoofing IP addresses could result in the disruption of
recording.
If you must p ss IP c mer video through “public” LANs, ensure
th t video is recorded prior to le ving the secure LAN. Then
encrypt it by using Virtu l Priv te Network (VPN) so th t neither
the video, nor its ddressing is re d ble on the LAN. M ny low-
cost routers support VPNs.

with PoE, PoE+, or High Power PoE
The NV- C1701 has a power inlet connector that receives 48 or 56 volts from an external Class 2 S LV desk-style power supply.
Power is distributed to:
1) the transceiver’s internal electronics;
2) the RJ45, provided the connected camera or other device provides the appropriate 27K ohm Po ‘discovery signature’.
+48V (or +56V) power is provided on pins 1&2 and 5&4, while 3&6 and 7&8 are at 0 V. The use of all four wire-pairs ensures
maximum distance, even for high-power loads, such as P/T/Z cameras.
3) the coax cable, where it is used by the control-room NV- C1701.
For fa lt/safety, never se more than two power s pplies within a network.

The distance capability of wire is dependant on its ability to deliver DC power, and separately, to deliver high-frequency
data signals.
The graph below shows maximum power delivery when using a 48V power supply. If you are using a 56V power supply,
your distances will be 2.6 times those shown in figure 4. If you are not delivering power to your camera (or other remote
device), then this graph does not apply. Figure 5 shows the maximum network data rate.
A Distance Calculator can be found at www.nvt.com.
PoE devices require a minimum of 43V to operate. With a 48V supply, we have 5V of allowable voltage drop on the wire.
With a 56V supply, we have 13V of allowable voltage drop on the wire.
The voltage will dip in proportion to the remote (camera) load. The graph below shows what distances are supported for
various loads and wire types.
●Start with the camera wattage at the left. Sometimes IP cameras are listed as to their PoE Class rather than
wattage. If this is the case, use the colored classes instead.
●Now read over to the right until you find your kind of wire. Then look up (feet) or down (meters) to find your
maximum wire distance.
●If your wire is not among the examples, simply measure its total resistance and find that value on the right side of
the graph. The maximum supported wattage is on the left.
