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-ET1801, or an NV-ER1804,
NV-ER1808i, or NV-ER1816i.
Connect the TBus building wiring to the TBus BNC or RJ45 jack on the
receiver.
If the receiver is an NV-ET1801 or an NV-ER1804, 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-ER1808i, or NV-ER1816i,
then connect its IEC power inlet and turn on the power switch.
This will provide power to the entire system, including the cameras.
The blue “Power” LEDs will begin to blink on both transceivers, indicat-
ing initalization. After 10 seconds, the blue LED will go on solid, and the
green LINK LED will go on indicating that the device has established
communication with another TBus transceiver.
Check the Quality LED. It should be green. An amber LED indicates a
weak signal, while a red LED 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 Ethernet RJ45 jack on the
receiver and either: 1) an IP camera video input on a Hybrid DVR, or 2)
an Ethernet switch allocated for video. See application examples on
pages 10 & 11.
The green Ethernet LED will illuminate when the Ethernet link is estab-
lished, and will blink when data traffic is present.
Verify Camera End LEDs
Check the LEDs on the NV-ET1801. The blue power LED should be on.
The green Link LED should also be on, indicating that the NV-ET1801 is
communicating with the receiver. The Quality LED should be green. An
amber LED indicates a weak signal, while a red LED indicates a poor
signal.
The green Ethernet LED will illuminate when the camera’s Ethernet link
is established, and will blink when data traffic is present. If the camera
is PoE device, the green PoE LED will also be on.
