2 Hardware Description
Product Overview
The Converter offers the most comprehensive network
extension and monitoring status. It is designed for
large workgroups who demand higher speed and
wider bandwidth. It allows migration and expansion
from a copper-based Ethernet to a fiber optic Fast
Ethernet.
It features automatic MDI detection setting. This
function allows for simple direct connection to a
workstation, switch or hub. Therefore, network
managers no longer need to worry about cable type
configuration when establishing a connection between
RJ-45 ports.
This Converter is equipped with an RJ-45 port and a
fiber optic ST or SC or WDM port. This allows it to
quickly integrate a 10/100Base-TX network into a
100Base-FX (fiber) network.
This Converter has the ability to support distances of
up to 2 kilometers for multi-mode fiber and up to 120
- 5 -

kilometers for long-haul single mode fiber between a
LAN switch, file server or another networking device.

3 Installation
To install your Converter, please see the following
procedures:
• Location
• Install the Converter
Location
The location selected to install the Converter may
greatly affect its performance. When selecting a site,
we recommend considering the following rules:
• Install the Converter in a fairly cool and dry place.
See Technical Specifications for the acceptable
temperature and humidity operating ranges.
• Install the Converter in a location free from strong
electromagnetic field generators (such as motors),
vibration, dust, and direct exposure to sunlight.
• Leave at least 10cm of space at the front and rear of
the unit for ventilation.
• Affix the provided rubber pads to the bottom of the
Converter to protect the case from scratching.
Install the Converter
This Converter utilizes ports with fiber and copper port
connectors functioning under Ethernet and/or Fast
Ethernet protocols.

10/100BASE-TX Port
The 10/100BASE-TX port supports network speeds of
either 10Mbps or 100Mbps, and can operate in half-
and full duplex transfer modes. This port also offers
automatic MDI/MDI-X crossover detection that gives
true "plug and play" capability - just plug-in the
network cable to the port and the port will adjust
according to end node device automatically. The RJ-
45 connector is suitable for UTP cable Category 3, 4,
5 or better.
100BASE-FX Port
The 100BASE-FX port adds a fiber Fast Ethernet link
to your network device. Compliant with IEEE 802.3u,
this port can transmits data at 100Mbps in full duplex
mode across distances of up to 2km over multi-mode
fiber-optic cable. The fiber port has a choice of three
fiber connector types: ST, SC and WDM.
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.
- 9 -
Page 14
10/100Base-TX to 100Base-FX Mini Converter
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 should be lit).
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 be lit).
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. Because invisible laser radiation may be
emitted from the aperture of the port when no cable is
connected, avoid exposure to laser radiation and do not stare
into open apertures.

Getting Connected
Powering On Unit
The Converter uses an AC power supply 100~240V
AC, 50~60 Hz. The Converter's power supply
automatically self-adjusts to the local power source
and may be powered on without having any or all LAN
segment cables connected.
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.
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.
3. Check the power LED of the Converter
4. When the device is powered on to verify that
power is applied. If not, check that the power
cable is correctly and securely plugged in.

Connecting Fiber Cable
When connecting fiber cable to a 100BASE-FX port
on the Converter, be sure the correct type - ST or SC
or WDM - connector is used. Follow the steps below
to properly connect fiber cable:
1. Remove and keep the ST/SC/WDM 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/WDM
port on the Converter and the other end to the
ST/SC/WDM port on the other device.
Note: When inserting the cable, be sure the tab on the plug
clicks into position to ensure that it is properly seated.
4. Check the corresponding port LED on the
Converter to make sure that the connection is
valid. (Refer to the LED chart in next section)

Connecting Copper Cable
The 10/100BASE-TX RJ-45 Ethernet port fully
supports auto-sensing and auto-negotiation.
1. Insert one end of a Category 3/4/5/5e type 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 be sure that the connection is valid.

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
performs
m

Try to
maintain
a bend
radius of
(m in.) 4x
the diameter
of the cable
for UTP and
100x for fiber.
Place cable ties
at regular
intervals - do
not over tighten
cable ties - try
to avoid using
with fiber.
Try not to
allow the
cable to
twist too
much - this
creates a
strain on
the internal
cables.
Do not s tretch

especially on
corners, in
vertical cable
trays and when
spanning long
distances.
