Nitek EL1500U - Manual (Page 5)

Installation & Setup
Equipment Requirements & Mounting: The process for utilizing the EL1500U is rather quick and easy. A
common topology involves a length of existing UTP (CAT5e/CAT6) cable (up to but not exceeding
2000ft/600m), the EL1500U transmitter and receiver pairs (ET1500U & ER1500U), an IP camera or other pe-
ripheral network device (both universally referred to as the Power Device or PD), and a 3rd party PoE injector/
inserter (or Power Sourcing Equipment/PSE). The camera 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 proper attached device operation. Additionally, all RJ45 termina-
tions 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 “Network Port” labeled RJ45 to the NITEK or 3rd party PoE injector/inserter or Power Sourcing
Equipment via a CAT5e/CAT6 patch cable. The ER1500U “Link Port” RJ45 enables connectivity to the length
of CAT5e/CAT6 UTP “Link” cable. The IP camera interfaces with the ET1500U “Network Port” labeled RJ45 by
a CAT5e/CAT6 patch cord. The output of the 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 dis-
cerns the proper direction of power & data flow to the network switch. Power (PoE) from the Power Sourcing
Equipment provides operational PoE for both the ET1500U and ER1500U units as well as for the attached the
camera. An illustration of this is represented below in the “Installment Topology - Type B” diagram.
Upon final termination the devices will undergo initialization and auto-configuration processes (see LED Indica-
tor chart on pg 7) which may take a number of seconds (time variations are device/installation/topology param-
eter 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
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:

Installment Topology - Type B
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 cable which
enables the transmission of up to 100Mbps of network data. Power for the units as well as for
the IP camera is derived from the 3rd party PoE Injector/Inserter. Total distance, via UTP cable,
between the EL1500C devices cannot exceed 2000ft/600m.

* PoE is introduced to the system by using a
PoE injector (IP1054) or 3rd party equivalent
in installations where the network switch in
not capable of producing Power over Ethernet.
