Power
Supply
Many installations that use the NV-ET1801 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 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-ET1801 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-ET1801 nearby in a clean dry
place. Ambient temperature must be between -40°F and +185°F
(-40°C to +85°C).
The NV-ET1801 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 (PoE) of
the camera and the Ethernet RJ45 jack on the NV-ET1801. Connect the
TBus building wiring to the TBus BNC or RJ45 jack on the NV-ET1801.
For most installations, the IP camera’s power will be low enough, and
the TBus distance short enough, so that the NV-ET1801 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
