NV-EC-1701U
Eo2™ Ethernetover 2-wire
Transceiver with PoE+
Model NV-EC1701U
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. 55 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
Phybridge’s award winning customer support and limited lifetime
warranty.

Advantages
• Transmit 10/100 BaseT
Ethernet up to 1,000ft
(305m)* over 4-pair cat5;
750ft (228m) over 18/2
(or similar 2-wire cable);
500ft (150m) over Shielded
Twisted-Pair
• Easy conguration, no PC
required
• Powers PoE, PoE+, or High
Power PoE cameras (or
other PoE devices), up to
50 watts*
• Built-in transient
protection; Industrial
temperature range
*Distance and number of devices supported may
be lower due to power supply capacity and wire
voltage-drop. See Wire Distance Charts on page 4.
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.

DATA SHEET
NV-EC1701U Power Data Distance Chart
The distance capability of wire is dependant on its ability to deliver DC power, and separately, to deliver high-frequency
data signals.
The graph below shows maximum power delivery when using a 55V power supply. If you are locally powering your
camera (or other remote device), then this graph does not apply.
PoE devices require a minimum of 43V to operate. With a 55V supply, we have up to 13V of allowable voltage drop on
the wire.
The voltage will dip in proportion to the remote (camera) load. The graph below shows what PoE power distances are
supported for various loads and wire types.
• Start with the camera wattage at the left. Sometimes IP cameras are listed as to their PoE Class rather than wattage.
• Now read over to the right until you nd your kind of wire. Then look up (feet) or down (meters) to nd your maximum
distance.
• If your wire is not among the examples, simply measure its total resistance and nd the value on the right side of the
graph. The maximum supported wattage is on the left.
• There are a wide variety of wire qualities. The graph below will help you determine your data throughput as a function
of wire type and distance.
