Installation
The default DIP switch settings (all switches in the UP position)
will work for most installations.
These are the steps required to configure the Perle S1110
Ethernet media converter:
1. Insert SFP Module (SFP Model only)
2. Set the Auto-MDIX jumper setting (optional).
3. Set the DIP switch settings (optional).
4. Install and connect the fiber cable.
5. Install and connect the copper cable.
6. 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-1110 will operate as an MDIX
device. By covering or strapping pins 2 and 3, the S-1110 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 copper (Switch 1)
Switch Position Mode
Up (default) Auto
Down Off
Note: Auto negotiation should only be turned off, if the copper link
partner does not support Auto Negotiation and fixed settings are
required by the copper link partner.
Auto: When enabled, the media converter will negotiate with its
link partner to determine the most optimal parameters for this
connection. The S-1110 will advertise capabilities of 10,100 and
1000 Mbps, full and half duplex as well as pause, and remote fault
capabilities to the link partner.
If the copper link partner does not support Auto negotiation, the S-
1110 will parallel detect to 10 or 100 Mbps and force Half Duplex
mode as per IEEE specifications.

Perle 10/100/1000 Ethernet Media Converter
Installation Guide
6
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) Smart Link Pass-Through Mode
Down Standard Mode
Smart 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 Smart 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.
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.
Fiber Fault Alert (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 immediately disable its fiber transmitter signal.
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 Fiber Fault Alert (FFA)
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 10/100/1000 Ethernet Media Converter
Installation Guide
7
passed through to the local copper connection thus notifying the
connected device.
If the media converter has been set to Smart Link Pass-Through
mode, the effect will be the same as FFA, 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: This feature only takes effect if Fiber Negotiation has been
turned off.
Disabled: The media converter will not monitor for or generate
Fiber Fault Alert.
The following diagram is an illustration of the operation of this
feature.
(A) – Remote Media Converter setup for Fiber Fault Alert Enabled,
Fiber Negotiation – OFF and Link Mode – Standard.
(B) – Local Media Converter setup for Fiber Fault Alert Enabled,
Smart Link Pass-Through On and Fiber Negotiation - OFF
1 – (A) Loses fiber connection on its receiver.
2 – (A) Sends FFA.
3 – (B) Detects FFA signal and shuts down the fiber link.
4 – (B) Drops link on copper connection because Smart Link
Pass-Through is configured.
5 – (A) Link on copper connection is not affected because Smart
Link Mode is set to Standard.
Duplex copper (Switch 4)
Switch Position Mode
Up (default) Full
Down Half

Perle 10/100/1000 Ethernet Media Converter

Full Duplex mode.
Down: The media converter will be set to Half Duplex mode.
Speed copper (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 switch setting for its Ethernet copper speed
connection.
Up: When Switch 5 is in the Up position, the S-1110 will force the
speed to 100 Mbps.
Down: When switch 5 is in the Down position the media converter
will force the speed to 10 Mbps.
When using a Gigabit SFP module)
Fiber Negotiation (Switch 6)
Switch Position Mode
Up (default) Auto
Down Off
Up: The Media Converter will negotiate Ethernet parameters on
the fiber connection. This will ensure that the most optimal
connection parameters will be in effect. If connecting to another
Perle Media Converter, this parameter should be set to Auto. The
Media Converter Module will advertise 1000Mbps, Full and Half
Duplex, no Pause.
Down: The Media Converter Module’s fiber will be fixed to
1000Mbps, Full Duplex.

When using a 100 SFP module
Full/Half Duplex on Fiber (Switch 6)
Switch Position Mode
Up (default) Full
Down Half
Up: The Media Converter Module will be set to Full Duplex mode
on its fiber link.
Down: The Media Converter Module will be set to Half Duplex
mode on its fiber link.
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 SFP Fiber Module
The S-1110-SFP model requires an SFP fiber module. Locate
appropriate fiber module and insert the SFP into the opening on
the front of the media converter.
1. Ensure the SFP module is properly seated.
2. The SFP module may be inserted before or after applying
power to the media converter
3. Proceed with cable connections.

Installing the Duplex Fiber Cable
Locate a 1000Base-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 1000Base-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 10/100/1000Base-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 Perle media converter supports Auto-MDIX which
allows a straight-through or cross-over Ethernet cable. See Auto-
MDIX Jumper Settings in this guide for jumper positions.

Other Features
Auto-MDIX
Auto-MDIX (automatic medium-dependent interface crossover)
detects the signalling on the 10/100/1000BASE-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 two 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. Ensure the transmitter and receiver
pairs are crossed.
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.
