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 enclosure case w/ transmitter, a receiver (ET1500CW & ER1500CW), an
IP camera or other peripheral network device (both universally referred to as the Power Device or
PD), and a 3rd party PoE Injector (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 then15.4 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 receiver 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 IP
camera/PD interfaces with the enclsoure encased ET1500CW via RJ5 (s) 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 PD. 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 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/PD operational specifications is recommended. If issues arise during
the installation process please see the “Trouble Shooting Tips” section (pg # 7). You may also

Installment Topology - Type B
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 Injector. Total distance, via RG59U cable, between the EL1500CW
devices cannot exceed 1,640ft./500m.
