Important Safeguards and Warnings
Attention:
Please read the following safeguards and warnings carefully before using the product in order to avoid
damages and losses.
Note
Do not expose the device to lampblack, steam or dust. Otherwise it may cause fire or electric shock.
Do not install the device at position exposed to sunlight or in high temperature. Temperature rise in
device may cause fire.
Do not expose the device to humid environment. Otherwise it may cause fire.
The device must be installed on solid and flat surface in order to guarantee safety under load and
earthquake. Otherwise, it may cause device to fall off or turnover.
Do not place the device on carpet or quilt.
Do not block air vent of the device or ventilation around the device. Otherwise, temperature in
device will rise and may cause fire.
Do not place any object on the device.
Do not disassemble the device without professional instruction.
Warning:
Please use battery properly to avoid fire, explosion and other dangers.
Please replace used battery with battery of the same type.
Do not use power line other than the one specified. Please use it properly. Otherwise, it may cause
fire or electric shock.
Special Announcement:
This manual is for reference only.
All the designs and software here are subject to change without prior written notice.
All trademarks and registered trademarks are the properties of their respective owners.
If there is any uncertainty or controversy, please refer to the final explanation of us.
Please visit our website for more information.
The function of the ITE being investigated to IEC 60950-1 is considered not likely to require
connection to an Ethernet network with outside plant routing, including campus environment.
The installation instructions clearly state that the ITE is to be connected only to PoE networks
without routing to the outside plant.

1 Product Overview
1.1 Product Introduction
Single-Port Long Reach Ethernet over Coaxial Extender is a type of converter from RJ45 to
BNC port, which supports long range power supply transmission via coaxial cable. It provides one BNC
coaxial port and one RJ45 port.
The product is equipped with two transmission modes which are 100Mbps and 10Mbps. It can be
modified according to the transmission distance.
1.2 Product Features
Supports IEEE802.3，IEEE802.3u and IEEE802.3X standards.
Supports IEEE802.3af and IEEE802.3at power supply standards.
Port: 1*RJ45 10/100Mbps, 1*BNC.
Supports RG59 coaxial cable: 400m/100Mbps, 1000m/10Mbps.
Supports MDI/MDIX self-adaption.
Supports long range power supply transmission via coaxial cable.
Operating temperature: -30~65℃.
1.3 Typical Application
The product is divided into transmitter (DH-LR1002-1ET) and receiver (DH-LR1002-1EC), which can be
used together with EoC passive converter (LR1002). It owns three types of networking schemes,
which is shown in Figure 1-1. ePoE switch or ePoE IPC means the specific switch or IPC with the
function of long distance.
