Nitek EL1500UW - Manual (Page 4)

Installation & Setup
Equipment Requirements & Mounting: The process for utilizing the EL1500UW is rather quick and
easy. A common topology involves a length of existing or new UTP (CAT5e/CAT6) cable (up to but not ex-
ceeding 2000ft/600m), the NEMA4 enclosed EL1500U transmitter and receiver, an IP camera or other pe-
ripheral network device (both universally referred to as the Power Device or PD), and a 3rd party PoE net-
work 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 then15.4W 48VDC @ 350mA of 802.3af power up to
25.5W 60VDC @ 600mA of 802.3at PoE+ power for proper attached device operation. Additionally, all RJ45
terminations are in accordance with 568B pin out standards.
The method for facilitating Ethernet communication and PoE over the UTP cable starts with connecting the
ER1500U receiver to the Power Sourcing Equipment, usually a switch (RJ45-to-RJ45) via a CAT5e/CAT6
patch cable. The ER1500U’s “Link Port” RJ45 enables connectivity to the length of CAT5e/CAT6 UTP “Link”
cable. The IP camera interfaces with the NEMA4 encased ET1500U via its “Network Port” labeled RJ45 by a
CAT5e/CAT6 patch cord. The output of the NEMA4/ET1500U intern connects to the length of CAT5e/CAT6
“Link” cable by its “Link Port” labeled RJ45 connector. Additionally, “PoE Out” as indicated on the devices
further discerns the proper direction of power & data flow. Power (PoE) from the Power Sourcing Equipment
provides operational PoE for both the NEMA4/ET1500UW and the ER1500U as well as for attached the
camera. An illustration of this is represented below in the “Installment Topology - Type A” diagram.
Upon final power up the devices will under go initialization and auto-configuration processes (see LED Indi-
cator 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 per-
formance referring to the PoE/distance chart (see pg 7) and adhering to the IP camera operational specifica-
tions is recommended. If issues arise during the installation process please see the “Trouble Shooting Tips”
section (pg 8). You may also contact our web based live tech support at:

Data
Shown in the diagram above, is the EL1500UW device (sold as a packaged set) consisting of a
transmitter, NEMA4 case, and receiver unit. They are connected to an Category cable which enables
the transmission of up to 100Mbps of network data. Power (PoE) for the units as well as for the
camera/network device is derived from the 3rd party PoE network switch. Total distance, via UTP
cable, between the EL1500UW devices cannot exceed 2000ft/600m.
