2 Hardware Description
Product Overview
The Converter is enhanced with Link Fault Signaling
(LFS) and Loopback Test (LBK) functions to offer the
most comprehensive network status monitoring and
connection diagnostics. 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.
It features DIP switches for manual half or full duplex
mode configuration on both copper and fiber ports. In
full duplex mode, this Converter has the ability to
support distances of up to 2 kilometers for multi-mode

fiber and up to 60 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
• Switch Settings
•NWay settings
•Link Fault Signaling
•Loopback Test
•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.

duplex
DIP 5 – Enables / disables Link Fault Signaling (LFS)

NWay DIP Switch Setting
Use the NWay DIP switch to activate NWay
operations.
Factory NWay DIP switch default set to ON position.
Check that the networking device to be connected to
the Converter has NWay support.
If YES: Check that the NWay DIP switch is set to the
ON position. The Converter will automatically
set the optimum speed and duplex mode on
the copper segment. Users can skip the
settings for DIP switches 2 and 3, when NWay
is activated.
If NO: Set the NWay DIP switch to the OFF position.
Then Use DIP switch 2 to manually select
between half (HD) and full duplex (FD) modes.
Use DIP switch 3 to manually select between
10Mbps or 100Mbps speeds. Set NWay
switch to OFF position when connecting to an
auto-sensing device that only supports
10/100Mbps detection. Some early switch

EX-9543 Enhanced 10/100Base-TX to 100Base-FX Converter

models only support auto-sensing of speed,
and NOT auto detection of speed and duplex
mode (auto-negotiation).
NWay DIP Switch Setting continue
Setting the duplex mode is feasible while the
media converter is “on-line”
Note: If you experience the following problems, please
check if the NWay switch is properly set.
1. The LNK (link) LED is not lit and the
connection cannot be established
2. The LNK LED is lit and the connection is ok,
but cannot transmit or receive data
3. The converter functions properly for a while,
then, it does not work. And then it works after
powering off and then on again.
Important
In order to configure DIP switches 2 (duplex
mode) and 3 (speed), you must set DIP
switch 1 (NWay) to the OFF position

Link Fault Signaling (LFS)
LFS is a “nice to have” function that is extremely
beneficial in terms of network status monitoring. The
LFS LED will immediately light to indicate when a
cable has been severed or when some other cause of
disruption in service has occurred. The LFS function
monitors both copper and fiber segments giving a total
connection status report.
Set LFS to ON position for normal operational use.
Set LFS to OFF position when installing cables or
when testing the network connection.
Note: The LFS feature influences both fiber and
copper segments. Therefore, when disruption occurs
on either segment, the LFS feature will be activated
and the LED will light to indicate that the entire
connection is down.
To appreciate the full benefits of LFS, four converters
can be used to build a primary and a secondary link.
They must be connected to a switch that supports
Spanning Tree or Fast Spanning Tree protocols. By
default, transmission of data will travel via the primary
link. Once a fault has been detected, transmission will

EX-9543 Enhanced 10/100Base-TX to 100Base-FX Converter
- 12 -
automatically be switched to the secondary link,
resulting in ‘non-stop’ network connectivity.
Loopback Test
This Converter features DIP switches to activate both
local and remote loopback diagnostic test functions.
Use local loop back to check if the copper segment is
connected properly, and use remote loop back to
check if the fiber segment is connected properly.
Please see Diagram below:
Dip Switch 6 ON: enables local loop back function
OFF: disables local loop back function
Dip Switch 7 ON: enables remote loop back function
OFF: disables remote loop back function
Make sure that the cables are connected properly
before getting started. Conduct either the local or
remote test, not both at the same time. Follow the
steps below to perform the diagnostic tests.

Local Loopback
1. Test Condition setup – for the function to produce
an accurate result, be sure to set switches
according to the table below:
Test Condition
2. Launch a loopback or diagnostics testing program
and follow the instructions given. Typically, the
instructions will be similar to the following:
a. Enter the number of test messages
(frame packets) to be sent (Between 1 –
1000)
b. Click on the START button
c. The program will send a testing
message looped in the copper segment,
and display a pass/fail result

produce an accurate result, set switches
according to the table below:
Test Condition
2. Launch a loopback or diagnostics testing program
and follow the instructions given. Typically, the
instructions will be similar to the following:
a. Enter the number of test messages
(frame packets) to be sent (Between 1 –

b. Click on the START button
c. The program will send a testing
message looped in the fiber segment,
and display a pass/fail result
NOTE: On a PC, use a program such as Sniffer to conduct the tests.
Other methods include the use of SmartBits series testing
equipment. If you do not have access to either method,
please contact your vendor for advice.

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.
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 two screws to mount the converter firmly in
place.
