PRODUCT DESCRIPTION
Before installing, NVT Phybridge recommends
downloading and reading the complete installation
manual from www.NVTPhybridge.com.
Do not attempt to install or service this equipment unless you
are skilled in the installation and maintenance of electronic
equipment and have successfully completed specific training for
this equipment.
Transceivers must be configured prior to use. See page 2.
Use one NV-EC1701 transceiver at each end of the coax. Up
to four remote transceivers and coax runs may be connected
to a fifth transceiver at the control room using the
NV-EC4BNC adaptor/splitter. Multiple splitters may be used
for larger systems.
Set the NV-EC1701 PoE toggle switch (located near the BNC
connector) to ON if the connected IP device requires PoE to
be delivered by the NV-EC1701 and to OFF if PoE should not
be delivered by NV-EC1701. This setting relates to power
delivery at the Ethernet RJ45 connection.
Connect a 55VDC power supply into one of the transceivers to
provide power to the entire system, including the cameras.
Data signals over the coax are capable of extended distances,
however voltage-drop in the 55V power distribution will often
reduce this maximum, depending on the camera’s current
draw and wire resistance.
Note: Within one network, up to two power supplies may
be deployed to support extended wire distances or higher
camera loads.

SAFETY WARNINGS AND PRECAUTIONS
The NVT Phybridge Model NV-EC1701 Ethernet over Coax
EoC Transceiver is a compact media converter that allows
10/100 BaseT Ethernet and PoE, PoE+, or high-power PoE to
be transmitted using coax cable. These EoC devices are
typically used in legacy installations where existing coax is
redeployed as part of an upgrade to IP cameras. 48-55VDC
class 2 power is delivered to one transceiver, which distributes
it to multiple remote transceivers, and their PoE cameras.
These transceivers are extremely simple to use, with no IP or
MAC address configuration required. Status LEDs indicate
power and link connectivity/activity for RJ45 and BNC ports.
Warranty
The NV-EC1701 is backed by NVT Phybridge’s award
winning customer support and limited lifetime warranty.
