Operation Manual
Introduction
The EL4500U system uses a four channel transmitter and a single channel receiver to extend Ethernet & PoE. The
EL4500U can be used on new or existing cable and is designed to greatly extend the distances to which IP cameras and
network devices can operate. In addition to network communication the EL4500U is ideal for PoE applications. It allows
all power to flow from the head end for most camera applications. In unique cases where high power PoE is needed it
can inject up to 25 watts of power at the transmitter end.

TYPE 1 Installation
Install EL4500U with a PoE Source Switch and IP Cameras
Refer to the diagram below when installing. A common hookup involves a length of network cable up to 2,000ft / 600m,
the EL4500U transmitter and receiver pairs (ET4500U & ER1500U), an IP camera or other peripheral network device
(both universally referred to as the Power Device or PD), and a 3rd party PoE network switch or Power Sourcing
Equipment/PSE.
To hook up the EL4500U begin by connecting the ER1500U to the Power Sourcing Equipment, usually a switch (RJ45-
to-RJ45) via a CAT5/CAT6 patch cable. Next connect the ER1500U “Link Port” to category cable running from the
ER1500U to the ET4500U. The IP cameras interface with the ET4500C via RJ45 and a CAT5/CAT6 patch cords. Power
for the IP Cameras is provides from the PS48 power supply connected to the ET4500U.
Note: This installation should be made by a
qualified service person and conform with local
codes.
