Complete Installation Guide

Model NV-EC1701U

EoC Ethernet over Coax Transceiver

with PoE, PoE+, or High Power PoE

CONFIGURATION INSTRUCTIONS

NV-EC1701U transceivers must be configured to communicate exclusively with other transceivers within their Network Group. This group typically consists of one NV-EC1701U located at the control room (usually connected to an ethernet switch or router), and up to four remote NV-EC1701U transceivers (usually connected to IP cameras or other remote IP devices).

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

Control Room Router Port Number

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.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device must not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Ethernet over Coax EoC Transceiver

Cat5

Figure 1 - Typical Installation

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.

55VDC Power Supply

LAN/WAN

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.

PoE CONSIDERATIONS

The NV-EC1701U transceiver supports full PoE, PoE+, and High Power cameras, as well as non-powered legacy

devices.

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.

Page 5 of 14

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.

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 enduser’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 dayto-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.

LAN/WAN

Firewall

Page 6 of 14

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.

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.

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.

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.

LAN/WAN

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.

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.

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.

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.
