Nitek EL1500CW - Manual (Page 5)

Installation & Setup
Equipment Requirements & Mounting: The process for utilizing the EL1500CW is rather quick and
easy. A common topology involves a length of existing coax cable (up to but not exceeding
1,600ft/500m), the NEMA4 enclosed case with EL1500CW transmitter, receiver (ET1500CW &
ER1500C), an exterior IP camera or other peripheral network device, and a 3rd party PoE network
switch (or Power Sourcing Equipment/PSE). The exterior PD and PSE must both be either 802.3af or
802.3at compliant. That is requiring or producing no more than 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 receiver to the Power Sourcing Equipment (RJ45-to-RJ45) via a CAT5e/CAT6 patch
cable. The ER1500C coax BNC connector enables connectivity to the length of RG59U coax cable.
The IP camera/PD interfaces with the enclosure encased ET1500CW via RJ45 and a CAT5e/CAT6
patch cord. The output of the ET1500CW intern connects to the length of RG59U cable by its BNC
connector. The NEMA 4 enclosure is typically mounted to an exterior surface or apparatus. Power
from the PSE provides operational PoE for both EL1500CW units and the camera. An illustration of
this is represented below in the “Installment Topology - Type B” diagram.
Upon final termination the devices will under go initialization and auto-configuration processes (see
LED Indicator chart on pg 6) 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 (see pg 6) and adhering to
the IP camera operational specifications is recommended. If issues arise during the installation pro-
cess please see the “Trouble Shooting Tips” section (pg 7). You may also contact our web based live

Installment Topology - Type B
Shown in the diagram above, is the EL1500CW device (sold as a packaged set) consisting of a transmitter,
NEMA4 case, and receiver unit. They are connected to an existing coax 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 de-
rived from the NITEK IP1054. Total distance, via coax cable, between the EL1500CW devices cannot exceed
1,600ft./500m.

PoE PoE Data
PoE is introduced to the system through a PoE injector
(NITEK IP1054 or a 3rd party equivalent) in installations
where the network switch does not have PoE capabilities.
