Introduction
The EL4500C system uses a four channel transmitter and a single channel receiver to extend Ethernet & PoE. The
EL4500C 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 EL4500C 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 EL4500C with a PoE Source Switch and IP Cameras
Refer to the diagram below when installing. A common topology involves a length of existing coax cable up to but not
exceeding 1,640ft / 500m, the EL4500C transmitter and receiver pairs (ET4500C & ER1500C), 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. Refer to the PoE power chart to determine maximum range for a PoE camera.
The method for facilitating Ethernet communication and PoE over RG59U cable starts with connecting the ER1500C to
the Power Sourcing Equipment, usually a switch (RJ45-to-RJ45) via a CAT5e/CAT6 patch cable. The ER1500C coax
BNC connector enables connectivity to the length of RG59U coax cable at the head end. The IP camera interfaces with
the ET4500C via RJ45 and a CAT5e/CAT6 patch cords. The output of the ET4500C intern connects to the length of
RG59U cable by its BNC connector at the camera end. Power from the PSE provides operational PoE for both
EL4500C units and the camera.

TYPE 2 Installation
Install EL4500C for Powering High Power PoE Cameras
Refer to the diagram below when installing. When installing without a PoE source device, the ER1500C can be powered
directly and will provide power for both the transmitter and PoE camera. The ET4500C can be used with a PS48 power
supply (available separately from Nitek) to power cameras up to 25 watts. When installing without a PoE source device,
the ER1500C must be powered directly.
A common topology involves a length of existing coax cable up to but not exceeding 1,640ft / 500m, the EL4500C
transmitter and receiver pairs (ET4500C & ER1500C), 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. The
PD and PSE must both be either 802.3af or 802.3at compliant. That is requiring or producing no more then 15.4 W
48VDC @ 350mA of 802.3af up to 25.5W 60VDC @ 600mA of 802.3at PoE+ power for proper attached device
operation.
The method for facilitating Ethernet communication and PoE over RG59U cable starts with connecting the ER1500C to
the Power Sourcing Equipment, usually a switch (RJ45-to-RJ45) via a CAT5e/CAT6 patch cable. The ER1500C coax
BNC connector enables connectivity to the length of RG59U coax cable at the head end. The IP camera interfaces with
the ET4500C via RJ45 and a CAT5e/CAT6 patch cords. The output of the ET4500C intern connects to the length of
RG59U cable by its BNC connector at the camera end. Power from the PSE provides operational PoE for both
EL4500C units and the camera.
Upon final power up the devices will under go initialization and auto-configuration processes (see LED Indicator chart)
which may take a number of seconds, time variations are device/installation/topology parameter dependent, to complete
before PoE and Ethernet communication commences. For optimal performance referring to the PoE Distance Chart and
adhering to the IP camera operational specifications is recommended.
