to the network equipment RJ45 output. The LINE port
uses RJ11 connector to connect the two core
cable (extension part).
2.
Connect the low-voltage power supply (DC12V) to the port
then power signal indicator lights Link
signal indicator lights
3. Connect the other end of the two-core cable with RJ11
connector to the remote Ethernet Extender LINE
port .The LAN port is connected to the
network equipments (such as network cameras) through
network patch cord.
4. Connect the low-voltage power supply (DC12V)
to the port , then red power signal indicator lights
Link signal indicator lights
5. When network transmission is smooth, the Ethernet
Extender automatically tries to connect. The LINE signal
indicator continuously flash about 10 times then
they light all the time. The DATA signal indicator
quickly flash show network signal transmission which is
smooth.
6. The RESET button are used when network
transmission is not smooth. It only can recover the
transmission channel of Ethernet Extender.

1)
Signal transmission cable must be the copper cable. Other
material cables will cause the decrease of signal transmission
quality and distance.
2)
Transmitting network data signal by mixing twisted pair,
telephone line connection is forbidden.
3)
This device has no waterproof design. Please use the product
in dry environment.
4)
Please choose matching power supply specification
(DC12V/1A) to supply power for devices respectively.
5)
Check the local unit and remote unit carefully before use.
Green indicator is remote unit. Red indicator is local unit.
If you install local unit and remote unit conversely, the devices
can not work.
6)
Long-distance cable connections must be standard connection
method, such as welding or use connectors.
7)
If the devices fail, you do not disassemble or repair, please
contact us timely.
