SFP Port: Gigabit Ethernet
RJ45 Port: 10/100/1000 BaseT IEEE 802.3ab
auto-negotiation, auto MDI / MDX crossover
Protection: Industrial transient protection
Wire type: Cat5 or better
Distance: up to 328 feet (100m)
T B u s L I N K I N T E R E R F A C E
Connectivity: Sixteen ports, each equipped with a BNC and RJ45
Power Source: Each port delivers class 2 (SELV) power
56VDC at up to 1 amp, to power remote
NVT transmitters and their PoE devices.
Wire type: Coax, single- or multi-pair UTP, 18/2, or STP wire
Impedance: 25 to 100
Ω
Topology: Bus architecture supports star, daisy-chain, or any
combination. One control-room Receiver may
support multiple remote TBus Transmitters.
Data throughput: 150 Mbps total network bandwidth*
with dynamic bandwidth allocation
Latency: 3 mS
Wire distance: Up to 8,000 feet, 1.5 miles (2.5 Km)*
Transmission technology: IEEE 1901
Encryption: 128-bit AES, through one-button Joining
* I M P O R T A N T N O T E :
Data rate, distance, and number of devices may be lower due to wire
voltage-drop, power supply capacity, or signal attenuation.
See pages 8 & 9.
W A R N I N G :
For safety, never use more than two power supplies within a TBus
channel. Never use more than one 60 watt remote power supply
on each TBus channel.

P O W E R S U P P LY
The NV-ER1808i contains a 250 watt 56VDC power supply that operates
off 100 to 240 VAC, 50/60 Hz. Current draw can be up to 4.5 amps. The
NV-ER1808i consumes up to 30 watts, leaving 220 watts for the eight
TBus ports.
Fuse rating: 250V 5A T
Use only the power cord provided with the unit or equivalent UL approved
type SPT-2, SVT, or SJT 18/3 AWG 100~240 VAC, 1 Amp 60°C max 15 ft
(4.5 m) long. One end with IEC380-C13 appliance coupler and the other
end with NEMA 1015P or equivalent for your country.
An optional external 250 watt power supply may be added for high load
applications, or for redundancy, bringing the total power to 500 watts.
The external power supply connections use an 8-conductor pluggable
Phoenixstyle connector suitable for up to 16AWG (1.3 mm) conductors.
Only one external 250 watt power supply may be used with each
NV-ER18016i. For multi-hub environments, up to three power supplies
are available in a shared 1U enclosure:
Single External Power Supply
Model NV-PS56-250W: 56V 250W
Dual External Power Supply
Model NV-PS56-250W-2 Dual 56V 250W
Triple External Power Supply
Model NV-PS56-250W-3 Triple 56V 250W
