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-EC1701U transceiver at each end of the cable.
Multiple remote transceivers and cable runs may be
connected to a transceiver at the control room. Torque all
screw connections to 2 in-lbs (0.2 Nm).
Set the NV-EC1701U PoE toggle switch (located near the
BNC connector) to ON if the connected IP device requires
PoE to be delivered by the NV-EC1701U and to OFF if PoE
should not be delivered by NV-EC1701U. 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 sytem, including the cameras (or
other remote IP devices).
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.
INSTALLATION INSTRUCTIONS
SAFETY WARNINGS AND PRECAUTIONS
The NVT Model NV-EC1701U Ethernet over 2-wire
Transceiver is a compact media converter that allows 10/100
BaseT Ethernet and PoE, PoE+, or high-power PoE to be
transmitted using 2-wire cable. These devices are typically
used in legacy installations where existing cable 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 (or other IP
devices).
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-EC1701U is backed by NVT Phybridge’s award
winning customer support and limited lifetime warranty.
