CONFIGURATION INSTRUCTIONS
The NV-EC1701U now comes in auto join mode for easy and quick deployments. The joining process is now only required when deploying more than 1 group of NV-EC1701
units. When deploying more than 1 group (max 4 end points and 1 head end) you are required to factory default the groups after the first group. You must first factory default the
units in the next group so they can be joined together into a group. Follow the un-joining method listed below and once factory defaulted you can then move to Step 3 to join the
newly factory defaulted units together.
Step One: Gather Materials
NV-EC1701U transceivers
55V power supply & line-cord (NV-PS55-60W)
Hook-up wire or BNC cable (not supplied)
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-EC1701U transceivers using hook-up wire or a BNC cable.
Observe polarity. Units will not power-up if the polarity is reversed.
Do not connect anything to the RJ45 connector.
Connect a 55V power supply to transceiver #1; Apply power.
Verify that the blue POWER LED on each transceiver illuminates.
Before proceeding to next step, wait for any green BNC LED that came on
during start up to go off, approximately 10 seconds.
Step Three: Joining
On transceiver #1, using the straightened paper-clip to access the small
push-button located behind and slightly above the RJ45 LED.
Firmly press and release this button.
The blue Power LED will begin blinking.
Then firmly press and release the same push-button on transceiver #2.
The blue Power LED will begin blinking.
Both transceivers have now entered Join Mode.
They will find each other and establish encrypted communication.
In about 10 seconds, the blue Power LEDs on both transceivers will return
to a steady on condition, 'and the green BNC LEDs will illuminate 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:
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 performing these
steps:
Disconnect the transceiver from the old network.
Connect a 55 VDC power supply to a transceiver.
Wait until its green BNC LED is lit.
Using the straightened paper-clip to access the small push-button located behind
and slightly above the RJ45.
Press and hold this button for 10-12 seconds until all of the LEDs flash.
Release the paperclip.
Observe that the green BNC LED goes on for ten seconds and then goes off.
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-EC1701U transceiver
involve the replacement of old analog equipment with new
IP devices, while reusing the installed wire.
To prevent damage, disconnect all analog equipment
before installing the IP equipment. The NV-EC1701U uses
the wire to deliver 55VDC.
Transceiver Conguration
NV-EC1701U transceivers must be congured to
communicate exclusively with other transceivers within their
Network Group. The conguration process is described on
page 3.
Connecting the Camera End
Install the new IP device. Mount the NV-EC1701U nearby
or within 328 feet (100 meters). Connect an RJ45 cable
between the network connector (PoE) of the IP device and
the RJ45 jack on the NV-EC1701U.
Connect the screw-terminal adaptor to the BNC jack on the
NV- EC1701U and connect one wire conductor to a terminal
marked “+”. Connect the other wire conductor to a terminal
marked “-”. Observe polarity so that it will match that of
the control-room end.
For most installations, the IP device’s power will be low
enough, and the wire distance short enough, so that the IP
device and its NV-EC1701U can receive power through the
wire. In most cases, a power supply will not be needed at
this end. For additional details, see pages 6 & 7.
Set the NV-EC1701 PoE toggle switch (located near the
BNC connector) to ON if the connected IP device requires
PoE to be delivered by the NV-EC1701 and to OFF if PoE
should not be delivered by NV-EC1701. This setting relates
to power delivery at the Ethernet RJ45 connection.
Connecting the Control-room End
Install a second NV-EC1701U at the control-room end of
the wire.
Connect the screw-terminal adaptor to the BNC jack on the
NV-EC1701U and connect one wire conductor to a terminal
marked “+”. Connect the other wire conductor to a terminal
marked “-”. Be sure to match the polarity of the remote-end
NV-EC1701U.
If rack-mounting is desired, use the NV-RMEC16U-90 tray,
which supports up to four NV-EC1701U transceivers.
Connect a class 2 (SELV) 55VDC power supply to the
power jack on the NV-EC1701U.
This will provide power to the entire system, including the
cameras. The Blue “Power” LEDs will illuminate on both
transceivers.
If the LEDs do not light, check the wire polarity. If the blue
LEDs blink, then the power supply is cycling on and o󰀨
due to an overload condition. Check for wire faults or
excessive loading.
Connect an RJ45 patch-cord between the RJ45 jack on
the NV-EC1701U and your ethernet switch.
The Green LEDs will illuminate when a network link is
established, and will blink when data tra󰀩c is present.
MULTIPLE CAMERAS
The NV-EC1701U transceivers communicate with each
other using a bus-architecture. This means that multiple
remote NV-EC1701Us may be connected together to
an NV-EC1701U at the control-room. The cables are
connected together using the screw-terminal adaptor.
Extra screw terminals are provided to allow easy
connection. Star, daisychain, or any combination of
topologies, including mixing of UTP and coax media may
be used.
Unlike coax-based signal distribution, the high frequency
signals that are transmitted can be susceptible to very
small amounts of crosstalk from other NV-EC1701U
network groups. For this reason, do not transmit signals
from di󰀨erent network groups within adjacent wire pairs.
The NV-EC1701U transceiver supports full PoE, PoE+,
and High Power cameras, as well as non-powered legacy
devices.
Unlike conventional PoE, voltage-drop and load current
must be conrmed by the installer. See “High Power
Extended Distance Considerations” on page 6 and use
the IP Distance Calculator at www.nvtphybridge.com.
NVT Phybridge’s Class 2 current limiting ensures safety
of the installation during fault conditions, while delivering
higher power (up to 90 watts) with more e󰀩cient allocation
amongst loads. Up to two power supplies may be used
within a network group.

Figure 2 - IP Camera & NVR Installation
IP CAMERA & NVR CONSIDERATIONS
TRANSCEIVER-TO-TRANSCEIVER NETWORK ARCHITECTURE
The NV-EC1701U transceivers provide transparent
end-to-end 10-baseT or 100-BaseT connectivity with
auto detection and autocrossover. 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 conguration instructions on page 3 before
installing.
Wire distances up to 1,500ft (450m) are supported,
although local power may be required for extended
distances. See page 9.
The NV-EC1701U supports TCP/IP, UDP, HTTP, Multi-
cast, and other standard protocols. This allows for the
transmission of other network tra󰀩c besides streaming
video.
For IP-based CCTV applications, there are some
network conguartions that are robust, and others that
are not recommended. In general, it is best to deploy
a separate LAN exclusively for video tra󰀩c.
Although it is possible to place IP cameras onto the end-
user’s “Enterprise LAN”, there are several disadvantages
in doing so. These include:
Tra󰀩c Management Considerations
When sharing the resources of a LAN, the nature of
the tra󰀩c must be well understood for it to operate
e󰀩ciently. 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 tra󰀩c.
Security Considerations
Most surveillance systems are installed specically
to protect against breaches in security. A shared LAN
provides potential opportunities for unauthorized
access to security assets. Sni󰀩ng IP addresses can
result in the unintended disclosure of IP cameras or
network vulnerabilities. Spoong IP addresses could
result in the disruption of recording.
If you must pass IP camera video through
“public” LANs, ensure that video is recorded
prior to leaving the secure LAN. Then encrypt it
by using a Virtual Private Network (VPN) so that
neither the video, nor its addressing is readable
on the LAN. Many low-cost routers support VPNs.

HIGH POWER EXTENDED DISTANCE CONSIDERATIONS
Figure 3 - Alternate Power Supply Location
The NV-EC1701U has a power inlet connector that receives 55 volts from an external Class 2 SELV 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 PoE ‘discovery
signature’. 55V 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; and
3) the coax cable, where it is used by the control-room NV-EC1701U.
For fault/safety, never use more than two power supplies within a network.

WIRE DISTANCE CHARTS
WIRE DISTANCE CAPACITY
The distance capability of wire is dependent 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 55V power supply. 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.nvtphybridge.com.
PoE devices require a minimum of 43V to operate. With a 55V 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.
● 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 Powered Device (camera) wattage at the left. Sometimes PoE devices 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 nd your kind of wire. Then look up (feet) or down (meters) to nd your
maximum wire distance. If your wire is not among the examples, simply measure its total resistance and nd
that value on the right side of the graph. The maximum supported wattage is on the left.

MULTICAST PACKET SUPPORT
Figure 6 - Multicast Network
On rare occasions, a customer will experience a problem
where a camera sending unicast packets performs
awlessly, but the NV-EC1701Us fail to deliver multicast
streams.
To understand this, we need to delve a little deeper into
how multicast networking works. To do this, we will rst
explore unicast packet transmission.
With unicast packets, there is a source (the camera)
and a destination (the NVR). Packets are generated
by the source and directed to a single destination. The
rst time a packet is sent, the switch has never heard
of the destination address. So it sends a broadcast
transmission to ALL destinations. The correct recipient
acknowledges the packet. The switch snoops in on
that response and memorizes which port is associated
with that transmission. Subsequent transmissions are
directed ONLY to the recipient’s port, thereby reducing
bandwidth on other parts of the network.
With multicast packets, the same bandwidth
considerations apply. Switches and routers do not
routinely deliver multicast tra󰀩c to all destinations.
Instead they rely on a special control protocol to identify
and report which multicast tra󰀩c should go where.
That protocol is called Internet Group Management
Protocol (IGMP). IGMP is a shared “querier” control
resource that is implemented on a host, such as a switch
or router, within the network. Virtually all routers and
most switches are equipped with an IGMP querier.
That host is responsible for sending IGMP queries to
multicast devices, requesting the generation of an IGMP
Report. That report is monitored by switches and routers
within the network. That monitoring is called IGMP
Snooping. These switches and routers keep a state
table and use it to determine to which ports to deliver
each multicast stream.
In practice, a multicast source (camera) sends its data not
to the destination, but to a ctitious “Group IP Address.”
Destination devices (the NVR), in response to an IGMP
querier request, send a request to the IGMP host asking
to be included as a destination for that group.
Switches and routers allow these multicast packets
through so they can be received by those interested
devices (NVR) and block them from being delivered
elsewhere. It would be inappropriate for the switch
to send a multicast stream everywhere, as it would
clog the network.
The NV-EC1701Us are not point-to-point devices. They
join together to function as a switch. Like a switch, they
listen for IGMP reports and block unknown multicast
packets. This is particularly important in a multi-camera
environment, as we do not want the stream from one
camera being delivered to all other cameras. That could
generate too much tra󰀩c.
On rare occasions an installation will be created without
the required IGMP querier. If the switches are not
equipped with IGMP snooping then they just deliver all
multicast tra󰀩c everywhere. If the NV-EC1701Us do not
receive IGMP reports, then they will BLOCK UNKNOWN
MULTICAST PACKETS, and the video will not pass
through.
An investigation can be performed as necessary using a
Packet Sni󰀨er, such as WireShark.
The bottom line is that an IGMP querier is required for a
properly congured multicast network. Contact NVT for
further information.

TROUBLESHOOTING PRODUCT DESCRIPTION
Conrm that the NVTP transceivers have been congured
to communicate with each other, per instructions on
page 3.
If you are experiencing problems, attempt to simplify
your setup. Test each cable segment separately. For
example, test the IP camera directly at the ethernet
switch without other equipment. Then add in the NVTP
transceivers, back-to-back. Test each segment of a long
cable- run independently. Attempt to isolate the problem.
Most IP camera installation problems involve conguring
the IP camera and the recorder to recognize each other.
If in doubt, connect the camera directly to the Ethernet
switch, bypassing the transceivers.
Consult the IP camera and/or recorder installation
manuals for conguration instructions, or contact the
camera or recorder manufacturer.
The NVT Phybridge Model NV-EC1701U Ethernet over
2-wire Transceiver is a compact media converter that
allows 10/100 BaseT Ethernet and PoE, PoE+, or high-
power PoE to be transmitted using 2-wire cable. These
devices are typically used in legacy installations where
existing cable is redeployed as part of an upgrade to
IP cameras. 48-55VDC class 2 power is delivered to
one transceiver, which distributes it to multiple remote
transceivers, and their PoE cameras (or other IP
devices).
These transceivers are extremely simple to use, with no
IP or MAC address conguration required. Status LEDs
indicate power and link connectivity/activity for RJ45 and
BNC ports.
NETWORK DIAGNOSTIC TOOLS
NVT Phybridge has developed a Console Utility that
can be downloaded from www.nvtphybridge.com. Once
installed on any Windows PC, the application scours
the network for NVTP devices, and reports each of their
MAC addresses, as well as the MAC addresses of any
other NVTP devices within its joined group.
Additional network tools, such as Packet Sni󰀨ers or
Tra󰀩c generators are available from other sources such
as LAN Shark, LANTra󰀩c, etc.
CUSTOMER SUPPORT
NVT Phybridge customer support is available for
