2 Hardware Description
Product Overview
The Converter is primarily designed for network or data
installations that require the migration of cable media
between conventional coppers based wiring to Fiber
based installations. These Converters have been
specifically designed to support both a RJ-45 jack and a
ST or SC fiber optic connector. This allows it to connect
10Base-T network to the 10Base-FL (fiber) networks.
In addition, this Converter features an MDI/MDI-X
crossover “push button” switch for direct connection to a
workstation, switch or hub. This allows the network
manager freedom to configure between crossover and
straight through when establishing a connection between
RJ-45 ports. This Converter can create potential distances
of up to 12km (39600feet) with single mode fiber between
2 networking nodes.

Location
The location selected for installing the Converter may
greatly affect its performance. When selecting a site, we
recommend considering the following rules:
1. Install the Converter in a fairly cool and dry place.
See Technical Specifications for the acceptable
temperature and humidity operating ranges.
2. Install the Converter in a location free from strong
electromagnetic field generators (such as motors),
vibration, dust, and direct exposure to sunlight.
3. Leave at least 10cm of space at the front and rear
of the unit for ventilation.
4. Affix the provided rubber pads to the bottom of the
Converter for grip, and to protect the case from
scratching.

MDI/MDI-X Connection
The MDI / MDI-X function alleviates the worry of cable
type configuration used for connecting the Converter with
a 10Base-T device. Simply follow the chart below when
connecting the Converter, and use the push button to
select MDI or MDI-X accordingly.

Install the converter
This Converter utilizes ports with fiber and copper port
connectors functioning under the Fast Ethernet protocol.
10BASE-T Port
The 10BASE-T port supports network speed of 10Mbps,
and is designed to operate in half-duplex transfer mode
only. This port also offers MDI/MDI-X crossover selection
to gives true "plug and play" capability. Just plug-in the
network cable to the port and adjust the push-button
according the chart above. The RJ-45 connector is
suitable for UTP cable Category 3, 4, 5 or better.
10BASE-FL Port
The 10BASE-FL port adds a fiber Ethernet link to your
network device. Compliant with IEEE 802.3, this port can
transmit data at 10Mbps in half-duplex mode across
distances of up to 2km through multi-mode fiber-optic
cable. The fiber port has a choice of fiber connector types:
ST and SC.

Desktop Installation
Follow the instructions listed below to install the Converter
onto a desktop location.
1. Locate the Converter in a clean, flat and safe position
that has easy access to AC power.
2. Affix the four (4) self-adhesive rubber pads to the
underside of the Converter.
3. Apply AC power to the Converter. (The green PWR
LED on the front panel should light).
4. Connect cables from the network partner devices to
the ports on the front panel. (The green LNK LED on
the front panel associated with the port should light).
This Converter can also be mounted on a vertical surface.
Simply use the underside of the unit as a template to
measure and mark out the position of the holes on to the
surface where the unit is to be installed. Then use the two
screws provided to mount the converter firmly in place.
Warning Please exercise caution when using power tools.
Also, install this unit away from damp or wet locations, or in
close proximity to very hot surfaces. These types of
environments can have a detrimental effect on the converter
and cables. An ideal location is a lightly cooled place such as
a typical equipment room.

12
Powering On Unit
The Converter uses external power supply 12V DC @
0.8A 50~60 Hz.
1. Insert the power cable plug directly into the receptacle
located at the back of the device.
2. Plug the power adapter into an available socket.
3. Check the front-panel LEDs as the device is powered
on to verify that the Power LED is lit. If not, check that
the power cable is correctly and securely plugged in.
Note: For International use, you may need to change the AC
power adapter cord. You must use a power cord set that
has been approved for the receptacle type and electrical
current in your country.

Connecting Fiber Cable
When connecting fiber cable to a 10BASE-FL port on the
Converter, be sure the correct type - ST or SC - connector
is used. Follow the steps below to properly connect fiber
cable:
1. Remove and keep the fiber port's rubber cover. When
not connected to a fiber cable, the rubber cover should
be replaced to protect the optics.
2. Check that the fiber terminators are clean. You can
clean the cable plugs by wiping them gently with a
clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables will
impair the quality of the light transmitted through the
cable and lead to degraded performance on the port.
3. Connect one end of the cable to the ST/SC port on the
Converter and the other end to the ST/SC port on the
other device.
4. Check the corresponding port LED on the Converter to
be sure that the connection is valid. (Refer to the LED
chart in next section)
Note: When inserting the cable, be sure the tab on the plug
clicks into position to ensure that it is properly seated.
Warning Because invisible laser radiation may be emitted
from the aperture of the fiber port when no cable is connected,
avoid exposure to laser radiation and do not stare into the
open apertures.

Connecting Copper Cable
1. Insert one end of Category 5 twisted pair cable into an
available RJ-45 port on the Converter and the other
end into the port of the network node.
2. Check the corresponding port LED on the Converter to
make sure that the connection is valid. (Refer to LED
chart in next section)

Appendix A
Cables
The following are some recommendations as to what you
should and should not do when installing cables.
Remember - cables are the deciding factor in network
performance.
2
4mm
6mm
Try to
maintain
a bend
radiusof
(min.) 4x
the diameter
of the cable
for UTP and
100x for fiber.
Try no t to
allow the
cableto
twist too
much - this
creates a
strain on
the internal
cables.
Place cable ties
atregular
intervals - do
not over tighten
cable ties- try
to avoid using
with fiber.
Do not stretch

especially on
corners, in
