NV-ER1808i
Many installations that use the NV-ER1816i receiver hub 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 PoE (Power over Ethernet), the legacy 24VAC
distribution may no longer be needed.
Disconnect all analog equipment from the cable before
installing the IP equipment. The NV-ER1816i uses the cable to
deliver 56V DC. To prevent damage, never connect analog
cameras, analog control-room equipment, or ethernet equip-
ment 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 cameras. Mount the TBus transmitter
(NV-ET1801 or NV-ET1804) nearby. Connect an RJ45 patch
cable between the network connector (PoE) of the camera and
an Ethernet RJ45 jack on the transmitter. Connect the TBus
building wiring to the TBus BNC or RJ45 jack on the transmitter.
For most installations, the IP camera’s power will be low
enough, and the TBus distance short enough, so that the trans-
mitter and its IP camera can receive power from the NV-ER1816i
at the head-end. In most cases, a power supply will not be needed
at the camera end. For additional details, see the distance chart
on page 8.
Connecting the Control-Room End
Install the NV-ER1816i receiver in a clean dry place, typically in
the control-room. Ambient temperature must be between -40
and +122°F (-40 to +50°C). Un-restricted airflow must be at
least 4 ft
3
/minute (0.1m
3
/ minute).
For rack-mounting, attach the supplied mounting brackets to the
TBus Hub chassis using the supplied screws. Note that the
brackets allow the Hub to be mounted with either the front or
rear facing out.
Connect the TBus wiring from as many as eight TBus building
locations to the TBus BNC or RJ45 jack on the receiver.
Connect power cord and switch on the NV-ER1816i. This will
provide power to the entire system, including the cameras.
The blue “Power” LEDs will begin to blink on the NV-ER1816i as
well as all transmitters, indicating initalization. After 10 seconds,
the blue LEDs will go on solid, and the green LINK LED will go on
indicating that the device has established communication with
another TBus transceiver.
Check each channel’s power LED status. A correctly connected
load will cause the channel’s power status LED to be green.
Connect an RJ45 patch-cord between the Ethernet RJ45 jack on
the NV-ER1816i and either: 1) an IP camera video input on a
Hybrid DVR, or 2) an Ethernet switch allocated for video.
Alternately, or in addition, insert an SFP module into the SFP slot,
and use this for your uplink, redundant, or daisy-chain backbone
connection. See application examples on pages 10 through 13.
For each connected uplink port, the green Ethernet LED will illu-
minate when the link is established, and will blink when data
traffic is present.
The NV-ER1816i has a browser-based Graphical User Interface,
which provides optional configuration, parameter monitoring,
and diagnostics. See page 15 for details.
Verify Camera End LEDs
Check the LEDs on the transmitter. The blue power LED should
be on. The green Link LED should also be on, indicating that the
transmitter is communicating with the NV-ER1816i. The Quality
LED should be green. An amber LED indicates a weak signal,
while a red LED indicates a poor signal.
For each camera connected, the transmitter’s green Ethernet
LED will illuminate when the Ethernet link is established, and will
blink when data traffic is present. If the camera is a PoE device,
the green PoE LED will also be on.
