Installation & Setup
Equipment Requirements & Mounting:
The process for utilizing the EL1500CW is rather quick and
simple. A common topology involves a length of existing coax cable (up to but not exceeding
1,640ft/500m), the NEMA4 enclosed case with EL1500CW transmitter, receiver (ET1500CW &
ER1500CW pair), an exterior IP camera or other peripheral network device (both universally referred to
as the Power Device or PD), 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. Additionally, all RJ45 terminations are in accordance
with 568B pinout standards.
The method for facilitating Ethernet communication and PoE flow over RG59U cable starts with
connecting the ER1500CW to the PSE (RJ45-to-RJ45) via a CAT5e/CAT6 patch cable. The
ER1500CW’s coax BNC connector enables connectivity to the length of RG59U coax cable. The
exterior IP camera/PD 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 PSE provides operational PoE for both EL1500CW units and the exterior PD. 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 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, are two EL1500CW devices (sold as a packaged pair) 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 for the units as well as for the
camera is derived from the 3rd party PoE network switch. Total distance, via RG59U cable, between
the EL1500CW devices cannot exceed 1,640ft./500m.
