The NVT Model NV-ET1801 TBus Single Port PoE+ Transmitter is a compact media converter that
allows 10/100 BaseT Ethernet and PoE+ power to be transmitted using virtually any kind of cable.
These devices are often used in legacy installations where existing cable is re-deployed as part
of an upgrade to IP cameras. 56 VDC class 2 power is delivered to one transceiver, which dis-
tributes it to multiple* remote transmitters, and their PoE, PoE+, or High Power PoE cameras*.
These transceivers are extremely simple to use, with no IP or MAC addressing required. Status
LEDs indicate power, Ethernet/PoE, and TBus connectivity/activity/quality. They are backed by
NVT’s award winning customer support and limited lifetime warranty.
* Distance and number of devices supported may be lower due to power supply capacity and wire voltage-drop. See Wire Distance Charts on page 9. Aggregate TBus band-
width is dynamically allocated (shared based on traffic), and decreases with wire distance. See Wire Distance Chart on page 9. Multicast requires an IGMP Querier, either in a
network switch, or within the NV- R1808i or NV- R1816i Receiver Hub. High bandwidth streaming devices (>15Mbps) that employ unusually “chatty”protocols (TCP/IP, TFTP,
etc.) are not recommended. Use RTP/UDP instead.

CONFIGURATION INSTRUCTIONS
The NV- T1801 TBus transmitter delivers high bandwidth encrypted thernet signals over virtually any kind of wire (Coax, UTP, STP, Un-twisted
wire, etc.). To provide utmost signal integrity and security, the NV- T1801 transceivers must be configured to communicate exclusively with other
transceivers within their TBus Network Group. This group typically consists of one or more remote Transmitters, typically located at the IP camera
and one Receiver, typically located at the control-room. Transmitters may be the NV- T1801 or NV- T1804. The Receiver may be the NV- T1801,
NV- R1804, NV- R1808i, or NV- R1816i.
Before functioning on the network, each NV-ET1801 must learn which other 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 aterials
• All 1800 series Transceivers • Device labels
• RJ45 patch-cord • IP Network Documentation Log
• Small paper-clip, partially straightened
Step Two: Connect Hardware
• Remove and discard the “Configure Before Use” labels.
• Use an RJ45 or BNC patch-cord to connect the TBus ports
of two Transceivers.
CAUTION: Never connect the RJ45 TBus port to an
RJ45 ethernet port.
• Apply power to one of the TBus devices.
• The blue POW R L D on each Transceiver will blink for 8 seconds and then go on.
• After 20 seconds, verify that the green TBus Link L D on each transceiver is off.
If a TBus Link 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 and release the small JOIN push-button
located on the bottom of the unit. Its blue Power L D will begin blinking.
• Depress and release the same push-button on the Transceiver #2. Its blue Power L D will begin blinking.
• Both Transceivers have now entered Join ode. 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, and
their green TBus Link L Ds will illuminate, indicating a successful Join.
• One TBus Link L D will remain on solid. The other may wink with data.
Step Four: Adding Transceivers (if required)
• Disconnect Transceiver #1 and replace it with a new un-joined Transceiver.
• 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:
• 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
This log may include essential documentation which will help you identify all system devices during
and after deployment. The NV- R1808i and NV- R1816i user interfaces have data-entry fields for
this purpose.
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:
• Apply power.
• The blue POW R L D on each Transceiver will blink for 8 seconds and then go on.
• Using the straightened paper-clip, depress the small JOIN push-button until the blue Power L D goes off (about 13 seconds).
• Un-joining is now complete.
If you are not sure that un-joining has been successful, remove and then re-apply power, and repeat.

Power
Supply
Many installations that use the NV- T1801 transmitter involve the
replacement of an analog camera with an IP camera, while reusing the
installed cable to deliver the TBus signal. Since most IP cameras
support Po (Power over thernet), the legacy 24VAC distribution may
no longer be needed.
Disconnect all analog equipment from the cable before installing
the
IP equipment. The NV- T1801 uses the cable to deliver 56V DC. To
prevent damage, never connect analog cameras, analog control-room
equipment, or ethernet equipment to a TBus port.
Transceiver Configuration
NVT TBus transceivers must be configured to communicate
exclusively with other transceivers within their Network Group.
This “Joining” configuration process is described on page 3.
Connecting the Camera End
Install the new IP camera. Mount the NV- T1801 nearby in a clean dry
place. Ambient temperature must be between -40°F and +185°F
(-40°C to +85°C).
The NV- T1801 comes with a single shoulder mount and 1/4” x 20
male/female standoff (model NV-CM2520), which allows it to be placed
between a box camera and its mount. (See figure 2.) The shoulder
mount may also be used in conjunction with a sheet-rock screw for
wall-mounting. (See figure 3.)
Connect an RJ45 patch cable between the network connector (Po ) of
the camera and the thernet RJ45 jack on the NV- T1801. Connect the
TBus building wiring to the TBus BNC or RJ45 jack on the NV- T1801.
For most installations, the IP camera’s power will be low enough, and
the TBus distance short enough, so that the NV- T1801 and its IP
camera can receive power from the head-end. In most cases, a power
supply will not be needed at this end. For additional details, see the

Connecting the Control-Room End
Install a TBus receiver at the control-room end of the TBus building
wiring. This receiver may be another NV- T1801, or an NV- R1804,
NV- R1808i, or NV- R1816i.
Connect the TBus building wiring to the TBus BNC or RJ45 jack on the
receiver.
If the receiver is an NV- T1801 or an NV- R1804, connect an
NV-PS56-60W (or NV-PS56-90W) 56VDC power supply to the power
jack on the receiver. If the receiver is an NV- R1808i, or NV- R1816i,
then connect its I C power inlet and turn on the power switch.
This will provide power to the entire system, including the cameras.
The blue “Power” L Ds will begin to blink on both transceivers, indicat-
ing initalization. After 10 seconds, the blue L D will go on solid, and the
green LINK L D will go on indicating that the device has established
communication with another TBus transceiver.
Check the Quality L D. It should be green. An amber L D indicates a
weak signal, while a red L D indicates a poor signal.
If your receiver is an NV-ET1801 or NV-ER1804, and the blue
LEDs continues to blink, check the power supply’s LED. If it is
cycling on and off then there is an overload condition. Check for
wire faults (including polarity) or excessive loading.
Connect an RJ45 patch-cord between the thernet RJ45 jack on the
receiver and either: 1) an IP camera video input on a Hybrid DVR, or 2)
an thernet switch allocated for video. See application examples on
pages 10 & 11.
The green thernet L D will illuminate when the thernet link is estab-
lished, and will blink when data traffic is present.
Verify Camera End LEDs
Check the L Ds on the NV- T1801. The blue power L D should be on.
The green Link L D should also be on, indicating that the NV- T1801 is
communicating with the receiver. The Quality L D should be green. An
amber L D indicates a weak signal, while a red L D indicates a poor
signal.
The green thernet L D will illuminate when the camera’s thernet link
is established, and will blink when data traffic is present. If the camera
is Po device, the green Po L D will also be on.

In Po parlance, the transmitter is known as Power Sourcing
quipment (PS ). It is capable of supporting conventional ether-
net, Po , and Po +, as well as high power devices up to 50
watts. As such, the transmitter can support an IP camera that
employs an ethernet powered P/T/Z/heater/blower.
Unlike conventional Po , voltage-drop and load current must be
confirmed by the installer. See page 8 and/or use the IP
Distance Calculator at www.nvt.com.
NVT’s Class 2 current limiting ensures safety of the installation
during fault conditions, while delivering higher power with more
efficient allocation amongst loads. WARNING: For safety,
never use more than two power supplies within a TBus
channel. Never exceed 120 watts within a TBus channel.
Never use more than one 60 watt remote power supply
on each Hub-based TBus channel.
Although NVT transceivers may be connected to Po -enabled
switch ports, they do not use Po power from the switch, rely-
ing instead on their own higher current 56VDC power sources.
Most IP cameras can support multiple video streams using vari-
ous protocols. MJP G and H.264 are the most common, and
can be transmmitted at various rates using unicast (point-
to-point) or multicast (single source with multiple destinations).
The NV- T1801 supports aggregate bandwidths up to 150
Mbps, allowing many devices to operate smoothly on one TBus
network. The 150 Mbps bandwidth is dynamically allocated
amongst all devices on the TBus network, so care must be
taken to not exceed the bandwidth capabilities of the transmis-
sion path.
Some protocols, such as TFTP, are particularly ‘chatty’, meaning
they generate a lot of acknowledgements that can easily clog a
network. NVT recommends simpler protocols for video trans-
mission, such as RTP over UDP.

NETWORKING CONSIDERATIONS
Unlike point-to-point devices that require one device at each
end of every cable, TBus transceivers communicate using a
bus-architecture.
This means that multiple remote camera-end transmitters may
be connected together to one receiver at the control-room.
Wire may be star topology, daisy-chained, or any combination.
TBus supports virtually any type of wire, including coax, UTP,
STP, even un-twisted wire. And different wire types can be
concatenated together, as needed.
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 con-
nections.
UTP and STP wire may be
connected to either the
BNC or the RJ45,
whichever is convenient.
NVT has screw-terminal
adaptors available for this
purpose. These adaptors
support up to four sets of wires, each up to 16AWG.
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 anagement 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 chang-
ing, 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 vulnerabilities. Spoofing IP addresses
could result in the disruption of recording.
If you must pass IP camera video through “public”
LANs, NVT recommends that video be 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. any low-
cost routers support VPNs.
NV-BNCT NV- C4BNC
NV-BNCA NV-RJ45A

On rare occasions, a customer will experience a problem where
a camera sending unicast packets performs flawlessly, but the
TBus transceivers “fail” to deliver multicast streams.
Because the TBus devices are delivering data amongst each
other in a distributed bus architecture, they need to be told
where to send which multicast streams. The TBus transceivers
count on the switch(es) to deliver that information.
Sometimes switches have been configured in a way that
assumes the TBus transceivers are edge devices (such as PCs
or IP cameras). In the interest of saving bandwidth, they do not
forward the IGMP control information. Without knowledge of
any request for a multicast stream, the TBus transceivers duti-
fully block that traffic.
Switches and routers (and NVT devices) do not routinely deliver
multicast traffic to all destinations. That could overload the net-
work. Instead they rely on a special control protocol to identify
and report which recipients (such as the VMS/NVR) are
requesting which multicast streams.
That protocol is called Internet Group Management Protocol
(IGMP).
How does IG P Work?
A “Querier” control resource is implemented on one network
host, such as a switch or router. Virtually all routers and most
switches are equipped with this capability. If there are multiple
hosts, the one with the lowest IP address is elected to perform
this Querier function.
The Querier is responsible for sending IGMP Queries to the
entire network, typically once every three minutes. Any device,
such as the VMS/NVR, that wishes to receive a particular
multicast stream responds to this Query by generating an IGMP
Report that is sent in the direction of the camera. That Report
is monitored and passed on by switches and routers within the
network. That monitoring is called IGMP Snooping.
These switches and routers each keep their own Routing Table
and use it to determine which ports should and should not
receive each multicast stream. It would be inappropriate for the
switch to send a multicast stream everywhere, as it would clog
the network.
The TBus transceivers are not point-to-point devices. They join
together to function as a distributed 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 traffic.
Switches and routers forward the IGMP Reports on to other
switches. However in the interest of not forwarding unneces-
sary traffic, many switches do not forward these reports to
‘Client Ports’, such as PCs.
If the TBus transceivers do not receive IG P Reports,
then they will BLOCK UNKNOWN ULTICAST PACKETS,
and the multicast video will not pass through.
Solutions
There are several ways to fix this: Running unicast only;
Influence the IT department to re-configure the switch; Operate
a separate “security” network (recommended); or use the
NV- R1808i or NV- R1816i Receiver hubs that have their own
table-entry list for multicast group addresses.

WIRE TYPE AND POWER DISTANCE
Page 8 of 15
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 56V power supply. If you are locally powering your
camera (or other remote device), then this graph does not apply. The graph on the next page shows the maximum data
delivery rate.
A Distance Calculator can be found at www.nvt.com.
PoE devices require a minimum of 43V to operate. With a 56V supply, we have up to 13V of allowable voltage drop on
the wire.
The voltage will dip in proportion to the remote (camera) load. The graph below shows what PoE power 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.
●Now read over to the right until you find your kind of wire. Then look up (feet) or down (meters) to find your
maximum distance.
●If your wire is not among the examples, simply measure its total resistance and find the value on the right side of the
graph. The maximum supported wattage is on the left.

LIMITED LIFETIME WARRANTY
Confirm that the NVT transceivers have been configured to com-
municate 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 a simpler
configuration first. Then add in the NVT transceivers, back-to-
back. Test each segment of a long cable-run independently.
Attempt to isolate the problem.
Most IP camera installation problems involve configuring the IP
camera and the recorder to recognize each other. If in doubt, con-
nect the camera directly to the thernet switch, bypassing the
transceivers. Consult the IP camera and/or recorder installation
manuals for configuration instructions, or contact the camera or
recorder manufacturer.
Which camera and NVT L Ds are on?
Can you ping the camera?
Test if unicast traffic passes smoothly but multicast traffic is
blocked. (See page 7.)
NVT has developed a Console Utility that can be downloaded from
www.nvt.com. Once installed on any Windows PC, the applica-
tionscours the network for NVT devices, and reports each of their
MAC addresses, as well as the MAC addresses of any other NVT
devices within its joined group.
Additional network tools, such as Packet Sniffers or Traffic gen-
erators are available from other sources such as LAN Shark,
LANTraffic, etc.
NVT customer support is available for consultation from 8:00 AM
to 5:30 PM PST Monday through Friday. In addition, emergency
after-hours callback support is available.
