Installation
The default dip 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 dip 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-110 will operate as an MDIX device.
By covering or strapping pins 2 and 3, the S-110 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
own Off
NOTE: Auto negotiation should only be turned off, if the copper
link partner does not support Auto Negotiation or fixed settings are
required by the copper link partner.
Auto: In this mode of operation the media converter will negotiate
Ethernet parameters on the copper connection. This will ensure
that the most optimal connection parameters will be used. If the
copper link partner does not support Auto negotiation, the S-110
will parallel detect to 10 or 100 Mbps and force Half Duplex mode
as per IEEE specifications.

Perle 10/100 Ethernet Media Converter – Installation Guide
5
Off: When the Auto Negotiation switch is set to the OFF position,
the media converter will not negotiate the Ethernet parameters
with the copper link partner. The parameters used by the media
converter will be determined by the Duplex (switch 4) and Speed
(switch 5) dip switch settings.
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 set-up 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 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 or copper port can occur 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 signal on the
fiber receiver, it will transmit a FEF signal to the remote media
converter. 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

Perle 10/100 Ethernet Media Converter – Installation Guide
6
passed through to the local copper connection thus notifying the
connected device.
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 result in bringing down the copper link, which will in
turn cause the transmit fiber link to be brought down.
NOTE: To generate or detect the FEF signal switch 3 needs to be
enabled.
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 Far End Fault enabled, Link
Pass-Through On and Auto Negotiation - OFF
1) (A) Loses fiber connection on its receiver.
2) (A) Sends FEF.
3) (B) Detects FEF signal and shuts down the fiber link.
4) (B) Drops link on copper connection because Link Pass-
Through is configured.
5) (A) Link on copper connection is not affected because Link
Mode is set to Standard.

Duplex (copper) (Switch 4)
Switch Position Mode
Up (default) Full
Down Half
NOTE: When Auto Negotiation (SW1) is set to Off, the media
converter will use this Duplex setting for its copper connection.
Full In the Up switch position; the media converter will be set to
Full Duplex mode.
Half: The media converter will be set to Half Duplex mode.
Speed (Switch 5)
Switch Position Mode
Up (default) 100
Down 10
NOTE: When Auto Negotiation (SW1) is set to Off, the media
converter will use this Speed setting for its Ethernet copper
connection.
100: Switch 5 in the Up position will try to establish the copper link
connection at 100 Mbps.
10: The media converter will try to establish the copper
connection at 10 Mbps.

Duplex (fiber) (Switch 6)
Switch Position Mode
Up (default) Full
Down Half
Full: The media converter’s fiber link will be set to Full Duplex
Mode.
Half: The media converter’s fiber will be set to Half Duplex Mode.
Loopback (Switch 7)
Switch Position Mode
Up (default) Disabled
Down Enabled
Disabled: The loopback feature is disabled. This is default
position for normal 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 link is not relevant since no
data is passed through to the copper side. This mode will
override all other switch settings.

Installing the Duplex Fiber Cable
•Locate a 100Base-X compliant duplex (2 strands) fiber cable with
appropriate connectors.
•Connect the fiber cables from one media converter to the other
media converter/switch/fiber device ensuring that the RX and TX
are reversed (crossed) at the opposite end.
Installing the Simplex Fiber Cable
• Locate a 10/100Base-X compliant simplex (1 strand) fiber
cable with appropriate connectors.
• Connect the fiber cable from one media converter to the other
media converter/switch/fiber device.
Installing the Copper Cable
•Locate 10/100Base-T 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 S-110 supports Auto-MDIX which allows a straight-
through or cross-over Ethernet cable. See page three in this
guide for jumper positions.

Other Features
Auto-MDIX:
Auto-MDIX (automatic medium-dependant interface crossover)
detects the signalling on the 10/100BASE-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.
Pause (IEEE 802.3xy):
Integrated Pause signalling is an IEEE feature that temporarily
suspends data transmission between two devices in the event that
one of the devices becomes overwhelmed. The Perle media
converter can generate and respond to Pause messages.
Troubleshooting
General
• Ensure power is supplied to the media converter – use of the
supplied power adapters is highly recommended.
• Ensure the remote device’s fiber connection type is
compatible with the media converter. 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, back to the local converter and
passed to the copper link.
