Product Description
The ION C2110 is a media converter module that provides an interface between 100Base-TX ports and
100Base-FX ports, allowing users to integrate fiber optic cabling into 100Base-TX copper environments.
Operating at Layer 1, the physical layer, data is passed through the converter at line speed, making it
ideal for applications where low latency is essential. The ION C2110 is a manageable device when
installed in a managed ION chassis.
Note: Some Documentation may have Transition Networks named or pictured. Transition Networks was
acquired by Lantronix in August 2021.

Set the 4-position DIP Switch (SW1)
The 4-position DIP switch is located on the edge of the printed circuit board (PCB). Use a small flatblade
screwdriver to set the recessed switches. The default setting is all Up (Enabled).
SW1
Sw #
Function Settings
1 Auto-Negotiation
Up = Enabled: Advertises 100 Mb/s Full-Duplex and Half-Duplex
(only during Auto-Negotiation).
Down = Disabled: Disables Auto-Negotiation. Operates at 100
Mb/s in the mode (either full- or half-duplex) of the attached device.
2 Pause
Applies ONLY if switch “1” is Up (and the C2110 is connected to
auto negotiating device(s) capable of pause control frame.
Up = Enabled: Allows negotiation of pause control frame.
Down = Disabled: Does not allow negotiation of pause control
frame.
3 Link Pass Through
(LPT)
Up = Enabled: Enables Link Pass-Through.
Down = Disabled: Disables Link Pass-Through.
4 Far End Fault
(FEF)
Up = Enabled: Enables Far-End Fault.
Down = Disabled: Disables Far-End Fault.
Note that PCB layout and components can vary by revision.
Note: Fixes at FW v 1.2.0: while in hardware mode, only the DIP switches can be used to set product
configuration. The software management interface will only display current operating and configuration
status. Changes to the products configuration can no longer be set via software, while in hardware-mode.
See the online Release Notes for more information.

Set AutoCross (E/D 3-Pin Jumper) (J4)
When the AutoCross feature is enabled, it allows either straight-through or crossover cables to be used
when connecting to 100Base-TX devices. AutoCross determines the characteristics of the connection and
automatically configures the unit to link up, regardless of the cable configuration. Note: AutoCross is
enabled by default. Lantronix recommends leaving jumper J4 in the “Enabled” position.
The 3-pin header J4 for the jumper is located on the PCB and is labeled “E” (Enabled) and “D” (Disabled).
The default is E(Enabled). Use a small needle-nose pliers to remove and position the jumper.
The J4 settings are shown and described below:
E- Enable: the C2110 connects automatically to either straight-through or crossover twisted-pair copper
cable.
D- Disable: either straight-through or crossover twisted pair copper cable must be installed, according to
site requirements.
Set Hardware / Software (H/S 3-Pin Jumper) (J5)
The 3-pin header J6 for the jumper is located on the PCB and is labeled “H” (Hardware mode) and “S”
(Software) mode. Use a small needle-nose pliers to remove and position the jumper.
The J5 settings are shown and described below:
H- Hardware: C2110 mode is determined by the 4-position DIP switch (SW1) settings (see above).
The default is Hardware mode.
S- Software: C2110 mode is determined by the most recently saved on-board ION software settings.

Lantronix C2110 Install Guide
33415 Rev. C https://www.lantronix.com Page 10 of 24
J6: E/H 3-Pin Jumper (Do Not Alter)
The default setting is “E” (Ethernet). Do not change this setting.
E - Ethernet: Ethernet mode of operation (Default - Leave as is).
H - HSTR: High Speed Token Ring mode. Do not use this setting.
Note that PCB layout and components can vary by revision.

Install the C2110 in the ION Chassis
CAUTION: Wear a grounding device and observe electrostatic discharge precautions when installing the
C2110. Failure to observe this caution could result in damage or failure of the C2110.
1. Carefully slide the C2110 into an open ION chassis slot, aligning it with the slot guides.
2. Ensure that the C2110 is firmly seated into the slot.
3. Push in and rotate the attached panel Fastener clockwise to secure the C2110 to the ION chassis.
Connect the Fiber Cable
1. Locate a 100Base-FX compliant fiber cable with a male, two-stranded TX to RX connector
installed at each end.
2. Connect the fiber cables to the C2110 as described below:
•Connect the male TX cable connector to the female TX port.
•Connect the male RX cable connector to the female RX port.
3. Connect the fiber cables to the other device (another C2110, hub, etc.) as described below:
•Connect the male TX cable connector to the female RX port.
•Connect the male RX cable connector to the female TX port.

Lantronix C2110 Install Guide
33415 Rev. C https://www.lantronix.com Page 12 of 24
Connect the Twisted-Pair Copper Cable
1. Locate a 100Base-TX compliant cable, with a male RJ-45 connector installed at each end.
2. Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the C2110.
3. Connect the RJ-45 connector at the other end of the cable to the RJ-45 port on the other device
(switch, workstation, etc.).
Operation
Status LEDs
The C2110 is designed to operate without user intervention. Use the status LEDs to
monitor the C2110 operation in the network.
PWR (Power): ON = Connection to powered ION Chassis backplane.
LKC (Copper Link): ON = Copper Link.
RXC (Receive Copper): Blinking = Data recieved on Copper link.
LKF (Fiber Link): ON = Fiber Link.
RFX (Receive Fiber): Blinking = Data received on Fiber Link.

Product Features
Auto-Negotiation
The Auto-Negotiation feature allows the C2110 to automatically configure itself to achieve the best
possible mode of operation over a link. The C2110 broadcasts its speed (100 Mb/s) and duplex
capabilities (full or half) to the other devices and negotiates the best mode of operation. Auto-Negotiation
allows quick and easy installation because the optimal link is established automatically. No user
intervention is required.
A scenario where the C2110 is linked to a non-negotiating device, disable Auto-Negotiation. In this
instance, the mode of operation will drop to the least common denominator between the two devices
(e.g., 100 Mb/s, half-duplex). Disabling this feature enables forcing the connection to the best mode of
operation.
Half-duplex Network (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the round trip delay limitations of
each Fast Ethernet collision domain. (A collision domain is the longest path between any two terminal
devices, e.g., a terminal, switch, or router.)
The 512-Bit Rule determines the maximum length of cable permitted by calculating the round-trip delay in
bit-times (BTU) of a particular collision domain. If the result is less than or equal to 512 BTU, the path is
good.
Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the type of cables used. See
“Ordering Information” on page 5for available C2110 models.
The 512-Bit Rule does not apply in a full-duplex network.
Pause Control Frame
The pause control feature can improve network performance by allowing one end of the link to signal the
other to discontinue frame transmission for a set period of time to relieve buffer congestion.
Note: If the pause control feature is present on all network devices attached to the C2110(s), enable the
pause control feature on the C2110(s). Otherwise, disable this feature.

Lantronix C2110 Install Guide
33415 Rev. C https://www.lantronix.com Page 14 of 24
Link Pass-Through (LPT)
When the Link Pass-Through feature is activated, it allows the C2110 to monitor both the fiber and copper
RX (receive) ports for loss of signal. In the event of a loss of an RX signal (1), the C2110 will
automatically disable the TX (transmit) signal (2), thus, “passing through” the link loss (3). The far-end
device is notified automatically of the link loss (4), which prevents the loss of valuable data transmitted
unknowingly over an invalid link.
Far-End Fault (FEF)
When a fault occurs on an incoming fiber link (1), the C2110 transmits a Far-End Fault signal on the
outgoing fiber link (2). In addition, the Far-End Fault signal also activates the Link Pass-Through, which in
turn disables the link on the copper portion of the network (3) and (4).
