Fast Ethernet Media Converter – Installation Guide 2
Overview
This document contains instructions necessary for the installation and
operation of the Perle Fast Ethernet Standalone Media Converters
(S-100). These products convert a 100Base-TX cable connection
(copper) to a 100Base-X connection (fiber). The fiber connection can
be either single mode (SM) or multimode (MM) and can operate over
different wavelengths and distances, depending on the model
selected (see table below).
Model Connector Mode - Distance Wavelength
S-100-M2xx2 SC/ST/LC MM - 2 km/1.2 mi. 1310 nm

Fast Ethernet Media Converter – Installation Guide 3
Installation
The default switch settings (all switches in the UP position) will work
for most installations.
There are five steps required to configure the Perle Fast Ethernet
media converter:
1. Set the Auto-MDIX jumper setting (optional).
2. Set the switch settings (optional).
3. Install and connect the fiber cable.
4. Install and connect the copper cable.
5. Power up the media converter.
Auto MDIX Jumper Settings
Note: The factory settings for Auto-MDIX will work for most
installations, but in the rare case that you need to modify the settings,
the procedure is below.
To access the Auto-MDIX jumper settings, unscrew the four side
screws on the top case and remove the cover plate. Locate the MDIX
AUTO jumper set as detailed below. By covering or strapping pins 1
and 2, the S-100 will operate as an MDIX device. By covering or
strapping pins 2 and 3, the S-100 will automatically detect the
Ethernet cable’s polarity. Removing the strapping is the same as
AUTO.
NOTE: The default jumper setting is Auto

DIP Switches
The DIP switches are accessible through the opening in the side of the
enclosure
Note: All switch changes take effect immediately and will result in a link
reset on both ports.
DIP Switch Settings
Auto Negotiation (Switch 1)
Switch Position
Mode
Up (default) Auto
Down Off
Auto: In this mode of operation the media converter will negotiate
Ethernet parameters on the copper connection. This will ensure the
most optimal connection parameters will be in effect. If the copper link
partner does not support Auto negotiation, the S-100 will default to
100 Mbps and Half Duplex mode.
Off: Auto Negotiation should only be turned off, if the copper link
partner does not support Auto Negotiation.
When the Auto Negotiation switch is set to the OFF position, the
media converter will operate at 100 Mbps and Full Duplex mode.

Fast Ethernet Media Converter – Installation Guide 5
Link Mode (Switch 2)
Switch Position
Mode
Up (default) Link Pass-Through Mode
Down Standard Mode
Link Pass-Through: In this mode, the link state on one connection is
directly reflected through the media converter to the other connection.
If link is lost on one of the connections, then the other link will be
brought down by the media converter.
If the installation has a media converter on both ends of the fiber link
and both are setup for Link Pass-Through, then a loss of copper link
on the far end device will propagate through both media converters
and will result in a loss of copper link at the near end device. This
would, therefore, resemble a direct copper connection.
Standard Mode: In this mode, the links on the fiber and copper sides
can be brought up and down independently of each other. A loss of
link on either the fiber ports or copper ports can take place without
affecting the other connection.
Far End Fault (Switch 3)
Switch Position
Mode
Up (default) Enabled
Down Disabled
Enabled: If the media converter detects a loss of fiber signal on the
fiber receiver, it will immediately send a FEF on the fiber link. This, in
effect, notifies the fiber link partner that an error condition exists on
the fiber connection.
If the remote media converter is set up for Far End Fault (FEF) and
the local media converter is set up with Link Pass-Through, a loss of
fiber link on either the transmit or receive line will be passed through
to the local copper connection thus notifying the connected device.

Fast Ethernet Media Converter – Installation Guide
If the media converter has been set to Link Pass-Through mode, the
effect will be the same as FEF, since the link loss on the fiber receiver
will bring down the copper link, which will in turn cause the transmit
fiber link to be brought down.
Note: This switch needs to be set to either generate or detect the
FEF signal.
Disabled: The media converter will not monitor for or generate Far
End Fault.
The following diagram is an illustration of the operation of this feature.
(A) – Remote Media Converter setup for Far End Fault Enabled, Auto
Negotiation – OFF and Link Mode – Standard.
(B) – Local Media Converter setup for Link Pass-Through and Auto
Negotiation - OFF
1 – (A) loses fiber connection on its receiver
2 – (A) sends an FEF
3 – (B) detects loss of link in its fiber receiver
4 – (B) drops link on copper connection through Link Pass-Through
5 – (A) Link on copper connection is not affected.
Unused (Switch 4)

Fast Ethernet Media Converter – Installation Guide 7
Pause (Switch 5)
Switch Position
Mode
Up (default) Enabled
Down Disabled
Enabled: When Auto Negotiation has been set to Auto (SW 1), the
media converter will use this setting for its Ethernet parameter
negotiation on the copper connection.
Disable: The media converter will not negotiate support for the Pause
feature.
Note: The media converter will not act on, or generate any Ethernet
Pause messages, but will pass them through to the end device. This
switch setting is provided so that the attached device (near end) can
negotiate its Ethernet parameters as if it was negotiating directly with
the far end device. The Pause switch setting on the media converter
should match the capabilities of the far end device.
Loopback (Switch 6)
Switch Position
Mode
Up (default) Disabled
Down Enabled
Disabled: The loopback feature is disabled. This is the normal
position for regular operation. The switch must be set to this position
in order for data to pass through the media converter.
Enabled: This is a test mode. All data received on the receive (RX)
fiber connection is looped back to the transmit (TX) fiber connection.
The state of the copper is not relevant and no data or link status is
passed through to the copper side.

Installing the Duplex Fiber Cable
•Locate a 100Base-X compliant duplex (2 strands) fiber cable
with male connections.
•Connect the fiber cables from one media converter to the other
media converter/switch/fiber device ensuring that the RX and TX
are reversed at the opposite end.
Installing the Simplex Fiber Cable
•Locate a 100Base-X compliant simplex (1 strand) fiber cable with
male connections.
•Connect the fiber cable from one media converter to the other
media converter/switch/fiber device.
Installing the Copper Cable
•Locate 100Base-TX compliant copper cables with male, RJ-45
connectors installed at both ends.
•Connect the RJ-45 cable between the Perle media converter
and the device.
Note: The Perle media converter supports Auto-MDIX, therefore a
straight-through or cross over Ethernet cable may be used. See page
three in this guide for jumper positions.

Fast Ethernet Media Converter – Installation Guide 10
Other Features
Auto-MDIX:
Auto-MDIX (automatic medium-dependant interface crossover)
detects the signalling on the 100BASE-T interface to determine the
type of cable connected (straight-through or crossover) and
automatically configures the connection.
Error Recovery:
In certain configurations, and under specific conditions where the
media converter brings down a link to convey status, there is potential
for a deadlock. Recovery is achieved by momentarily restoring the
link to see if the original failure has been resolved. If it has not, the
link will be forced down again, however if the original problem has
been resolved, the link will be restored.

Fast Ethernet Media Converter – Installation Guide 11
Troubleshooting
General
•Ensure power is supplied to the media converter – use of the
supplied power adapters is highly recommended.
•Ensure both devices on either end of the fiber are compatible. If
using a simplex fiber connection, ensure that you have both an
Upstream (U) and Downstream (D) media converter.
•Ensure all cabling is of the correct type and is in good working
order..
•For duplex fiber connections, ensure the RX and TX has been
reversed between the 2 media converters.
No connectivity
If unable to get full connectivity with all DIP switches in the UP
position, this procedure is recommended for troubleshooting.
Method 1
1) Set the Link mode to Standard (SW2 – Down) on both media
converters. Leave all other switches in the Up position.
2) Connect the near end device to the copper connection. The LKC
LED indicates good copper connection. If the LKC LED is not lit, then
check the copper cable and the attached device.
3) Repeat for the far end media converter.
4) Connect the fiber cable to both media converters. The LKF LED
indicates good fiber connection. If no LKF LED then check the fiber
cabling.
5) Return units to desired configuration.
Method 2:
The fiber connection can also be verified by configuring the remote
media converter for loopback mode. The LKF LEDs on both media
converters should be lit. Data should pass through the local
converter, over the fiber connection to the remote media converter. At
the remote media converter, the data will be looped back and passed
through the fiber, once again, to pass through the local converter to
the copper link.
