Nitek EL1500CW - Manual (Page 4)

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 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 ca-
ble. The exterior IP camera interfaces with the NEMA4 encased ET1500CW via RJ5 (s) and a CAT5e/
CAT6 patch cord. The output of the ET1500CW in turn 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 ER1500C provides operational PoE for both ET1500CW unit and the exterior camera. An illus-
tration 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 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 A
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 derived from the 3rd party PoE network switch. Total distance, via coax
cable, between the EL1500CW devices cannot exceed 1,600ft./500m.
