2 Hardware Description
Product Overview
The Converter is primarily designed for larger
workgroups, demanding more speed and bandwidth,
and requiring expansion of the Fast Ethernet network.
It features a MDI/MDI-X crossover “push button”
switch for direct connection to the workstation, switch
or hub. Now the network manager does not need to
worry about the cable configuration (crossover or
straight through) when establishing a connection
between RJ-45 ports.
The Converter features both a RJ-45 jack, and a ST,
SC, or WDM fiber optic connector that allows it to
connect a 100Base-TX (copper) network to the
100Base-FX (fiber) network.
Its features Auto-Negotiation support which allows the
Converter to support connection with leading NWay

100Base-TX to 100Base-FX Converter
Switches. At full duplex, the Converter can create
potential distances of up to 2 kilometers for multi-
mode fiber and 60 kilometers for long haul single
mode fiber between a LAN switch, hub or a file server.
Note: It is not recommended to use the Converter in
half-duplex mode as back-to-back distance for
multi-mode fiber will only be 412m.

Installing Your Converter
In this chapter, we will take a look at how to install
converters within its operating environment. First, it is
important to unpack the Converter and ensure that all
the components listed in Package Contents are
present.
•Location
•MDI/MDI-X Connection
•NWay Push-Button Switch Setting
•Installing Converter
•Desktop Installation
•Powering On Unit
•Connecting Fiber Cable
•Connecting Copper Cable

100Base-TX to 100Base-FX Converter
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 100Base-TX device. Simply follow the chart
below when connecting the Converter, and use the
push button to select MDI or MDI-X accordingly.

NWay Push Button Switch Setting
Use the NWay push button switch to activate NWay
operations.
Note: Factory NWay switch default set to ON position.
ON: Activates NWay auto-negotiation operation
mode. Set NWay switch to ON when
connecting to an auto-negotiation device. The
function will determine the highest possible
speed and duplex mode in copper segment.
OFF: Deactivates NWay auto-negotiation operation
mode. Set NWay switch to OFF when
connecting to an auto-sensing device that
only supports 10/100 detection. Some early

100Base-TX to 100Base-FX Converter

switch models only support auto-sensing of
speed, and NOT auto detection of speed and
duplex mode (auto-negotiation).
Note:
Setting the duplex mode is feasible while the media
converter is “on-line”

100Base-TX to 100Base-FX Converter
Install the converter
This Converter utilizes ports with fiber and copper port
connectors functioning under the Fast Ethernet
protocol.
100BASE-TX Port
The 100BASE-TX port supports network speed of
100Mbps, and can operate in half and full duplex
transfer modes. This port also offers MDI/MDI-X
crossover detection that gives true "plug and play"
capability - just plug-in the network cable to the port
and adjusts the push-button according the chart above.
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 transmit data at 100Mbps in full 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, SC and WDM.

100Base-TX to 100Base-FX Converter
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.

100Base-TX to 100Base-FX Converter
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.
