Overview
This document contains instructions necessary for the installation and
operation of the Perle 10/100 Ethernet Media Converter Module(s) (C-110
and CM-110) that are used in conjunction with a Perle MCR Chassis. The C-
110 are unmanaged media converter modules, and the CM-110 are the
managed versions. These products convert a 10/100Base-T 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 (see table below). For
information on management features of the CM-110 module, refer to the
MCR-MGT Module User’s Guide.

Installation
The module comes equipped with a bank of DIP switches and jumpers
for setting configuration.
The default dip switch settings (all switches in the UP position) and
default jumper settings will work for most installations.
The following steps are used to configure the Perle 10/100 Ethernet
Media Converter Module:
1. Set the Auto-MDIX jumper (optional).
2. Set the Auto-Config jumper (CM-110 only) (optional)
3. Set the DIP switch settings (optional).
4. Insert the Media Converter Module into the Chassis.
5. Connect the fiber cable.
6. Connect the copper cable.
Auto-MDIX Jumper
Note: The factory settings for Auto-MDIX will work for most
installations, but if there is a need to modify the settings, follow the
procedure below.
The AUTO-MDIX jumper (J5) is located on the upper edge, at the
midpoint of the module (see diagram below for labelling).. By covering
or strapping pins 2 and 3(AUTO), the C-110 and CM-110 will
automatically detect the Ethernet cable’s polarity and configure itself
as either an MDI or an MDIX device. By covering or strapping pins 1
and 2(MDIX), the C-110 and CM-110 will operate as an MDIX device
Removing the strapping is the same as AUTO.
NOTE: The default jumper setting is AUTO

Perle 10/100 Media Converter Module – Installation Guide
4
Auto-Config Jumper (CM-110 only)
The Auto-Config jumper (J6) is located just below the Auto-MDIX
jumper (see above). Refer to the diagram below for labelling. This
jumper only applies to CM-110 modules.
Strapping pins 1 and 2 of the jumper will set the module in SW mode
and strapping pins 2 and 3 will set it in Auto Config mode.
Auto: When set to Auto the module will, at power-up, check its
internal flash memory to see if configuration information has been
downloaded to it from a management module. If so it will use this as
its running configuration. If there is no configuration in flash it will read
the settings of the DIP switches and use those as its running
configuration.
SW: When set to SW (Switch), the module will, at power-up, read the
settings of the DIP Switches and use those as its running
configuration. It will ignore any configuration information in its flash
memory.
NOTE: The default jumper setting is Auto

Auto Negotiation (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 or fixed settings are
required by the copper link partner.
Auto: In this mode of operation the Media Converter Module 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 Media
Converter Module will parallel detect to 10 or 100 Mbps and force
Half Duplex mode as per IEEE specifications.
Off: When the Auto Negotiation switch is set to the OFF position, the
Media Converter Module will not negotiate the Ethernet parameters
with the copper link partner. The parameters used by the Media

Converter Module 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 Module to the other
connection. If the link is lost on one of the connections, then the other
link will be brought down.
With Media Converters on both ends of the fiber link and both setup
for Link Pass-Through, a loss of copper link on the far end device will
propagate through both Converters and will result in a loss of copper
link at the near end device. This would, in effect, 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 Module detects a loss of receive
fiber signal, 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

Perle 10/100 Media Converter Module – Installation Guide
7
fiber link on either the transmit or receive line will be 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: If it is required to either generate or detect the FEF signal, then
the FEF switch needs to be set.
Disabled: The Media Converter Module 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.

Down Enabled
Disabled: This is the setting for normal operation. The switch must be
set to this position in order for data to pass through the Media
Converter Module.
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.

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 Module 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 Module can generate and respond to Pause messages.

Troubleshooting
General
•Ensure that the Media Converter Module is securely seated in the
chassis. The PWR LED should be on.
•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 two Media Converters.
No connectivity
If unable to get full connectivity with all DIP switches in the UP
position, these methods are recommended for troubleshooting.
Method 1
1. If the Module is a CM-110, set the Auto-Config jumper (J6) to
SW so that DIP switches are being read.
2. Set the Link mode to Standard (SW2 – Down) on both Media
Converters. Leave all other switches in the Up position.
3. 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. Repeat for
the far end Media Converter.
4. Connect the fiber cable to both Converters. The LKF LED
indicates good fiber connection. If no LKF LED then check the
fiber cabling.
5. Return converters to desired configuration.

Perle 10/100 Media Converter Module – Installation Guide
16
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.
Note: If troubleshooting a CM-110, setting the Auto-Config jumper
(J6) to SW will ensure the DIP switches are being read.
