The NVT Model NV-EC1701U Ethernet over 2-wire Transceiver is a compact media converter that
allows 10/100 BaseT Ethernet and PoE+ power to be transmitted using ordinary 2-wire 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 distributes 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 and link connectivity/activity for each port. 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 5.
Bandwidth is dynamically allocated. Multicast requires an IGMP Querier within your network switch. High bandwidth streaming devices (>15Mbps) that
employ unusually “chatty”protocols (TCP/IP, TFTP, etc.) are not recommended. Use RTP/UDP instead.

RJ45 ETHERNET INTERFACE

Connectivity: RJ45, auto-crossover

Wire type: Cat5 or better

Distance: up to 328ft (100m)

Speed: 10/100 Base T, half/full duplex, auto-negotiation

auto MDI/MDIX cross-over

Latency: 3mS

Data throughput: 85Mbps ±10% useable bandwidth per network

Example: Four megapixel cameras, all sharing one
coax network, each sending 20Mbps video stream(s).

Power Output: This Power Sourcing Equipment (PSE) supports

Powered Devices (PDs) that are compatible with
IEEE 802.3af/at, or PDs that draw up to 50 watts*.
For maximum power/distance, 56 VDC appears
on all eight RJ45 pins, and are current-protected
and transient-protected.

2-WIRE BUILDING WIRING INTERFACEE

Connectivity: Screw terminals using the NV-BNCA adaptor

Impedance: 25 to 100Ω

Distance: See pages 5 & 6

Topology: Bus architecture supports star, daisy-chain, or any

combination. One control-room NV-EC1701U may support
multiple remote NV-EC1701Us.

Transmission technology: IEEE 1901, 128-bit AES encryption

*IMPORTANT NOTE:

Distance will often be shorter due to power supply capacity and wire
voltage-drop. See Maximum Per-Camera Wire Distance Chart on page 5.

WARNING: For safety, never use more than two power
supplies. Never exceed 120 watts.

LED STATUS INDICATORS

Power: Blue “Power On”

BNC/2-wire interface: Green “Link”

RJ45 Interface: Green “Link”

POWER CONSUMPTION

Consumption per transceiver: ≤ 3.0 W @ 10 to 56 VDC

Generated heat: 10 BTU/hour

Total system consumption: = total consumption of transceivers

+ total consumption of PDs (IP cameras)

+ total power dissipated in the wire
