Installation & Setup
Equipment Requirements & Mounting: The process for utilizing the EL1500U is rather quick and easy. A com-
mon topology involves a length of existing UTP cable (up to but not exceeding 2000ft/600m), the EL1500U trans-
mitter and receiver pairs (ET1500U & ER1500U), an IP camera or other peripheral network device (both univer-
sally 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
then15.4 W 48VDC @ 350mA of 802.3af power up to 25.5W 60VDC @ 600mA of 802.3at PoE+ power for prop-
er attached device operation. Additionally, all RJ45 terminations are in accordance with 568B pin out stand-
ards.
The method for facilitating Ethernet communication and PoE flow over the UTP cable starts with connecting the
ER1500U to the PSE (RJ45-to-RJ45) via a CAT5e/CAT6 patch cable. The ER1500U’s “Link Port” RJ45 enables
connectivity to the length of CAT5e/CAT6 UTP cable. The IP camera/PD interfaces with the ET1500U via
“Network Port” labeled RJ5 by a CAT5e/CAT6 patch cord. The output of the ET1500U intern connects to the
length of CAT5e/CAT6 cable by its “Link Port” labeled RJ45 connector. Additionally, “PoE out” as indicated on
the devices further discerns the proper direction of power & TCP/IP data flow. Power from the Power Sourcing
Equipment provides operational PoE for both EL1500U units and attached the camera. An illustration of this is
represented below in the “Installment Topology - Type A” diagram.
Upon final termination the devices will undergo initialization and auto-configuration processes (see LED Indicator
chart on pg 7) which may take a number of seconds (time variations are device/installation/topology parameter
dependant) to complete before PoE and Ethernet communication commences. For optimal performance referring
to the PoE/distance chart (see pg 7) and adhering to the IP camera/PD operational specifications is recommend-
ed. If issues arise during the installation process please see the “Trouble Shooting Tips” section (pg 8). You may

Installment Topology - Type A
Shown in the diagram above, are two EL1500U devices (sold as a packaged pair) consisting of
a transmitter and receiver unit. They are connected to a length of CAT5e/CAT6 UTP cable
which enables the transmission of up to 100Mbps of network data. Power for the units as well as
for the camera is derived from the 3rd party PoE network switch. Total operating distance of
UTP cable between the EL1500U devices cannot exceed 2000ft/600m.
