1.4 Special Functions
1.4.1 Auto MDI/MDI-X Function
This function allows the TP port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically.
1.4.2 Auto-negotiation Function
When TP port is set on Auto-negotiation mode (SW1:ON), it is featured with auto-negotiation function and full
capability. It performs a negotiation process for the speed and duplex configuration with the connected device
automatically when each time a link is being established.

-11-
1.4.3 Far End Fault Function
The FX port is facilitated with this function, which conforms to IEEE 802.3u 100BASE-FX specifications.
When the FX port detects a link failure on its receiving circuitry, it will send out an FEFI (Far End Fault
Indication) signal to the remote connected device to indicate a remote fault is detected. It also is capable to
receive FEFI signal sent from the remote link partner. Upon receiving an FEFI signal, it indicates a link failure
occurred on the transmitting path. This function allows the converter to report a fiber link fault even when a
link failure occurred on transmitting fiber cable.
1.4.4 Link Fault Pass Through Function
When this function is enabled, a link fault detected on the TP port will force a link down on the FX port.
Similarly, a link fault detected on the FX port will also force a link down on the TP port. As illustrated in the
following figure, this function allows to pass TP link fault to the remote link partner and makes the converter
like a TP cable extender.
1.4.5 Remote TP Port Monitoring Function
The converter provides LED indicators labeled RTP LINK/100M/FDX to display the TP port status of its
remote link partner on FX port. As illustrated in the following figure, the remote MC must be enabled for

-12-
periodical status report.
1.4.6 Loop Back Test Function
As illustrated in the following figure, the local MC starts a loop back test by pressing the loop back test button.
It sends test frames from its FX port to the remote MC. The remote MC forwards the received test frames back
to local MC from its FX port. The local MC verifies the loop back test frames and display the test result on
RTP LINK/100M/FDX LEDs. This function can help installer to check the full path from a local MC through
fiber to a connected remote MC and back to local MC.

2. Installation
2.1 Unpacking
Check that the following components have been included:
Installation guide (or contained in the product CD)
10/100 Media Converter
One AC power adapter
If any item is found missing or damaged, please contact your local reseller for replacement.
2.2 Mounting the Device
Desktop Mounting
The media converter can be mounted on a desktop or shelf. Make sure that there is proper heat dissipation from
and adequate ventilation around the device. Do not place heavy objects on the device.
Wall Mounting
The media converter also can be mounted on a wall. On bottom of the device, wall mounting hole is provided
for wall mounting.
Installation into Center ChassisKC-1300
The media converter also can be installed in KC-1300 center chassis. The center chassis provides the power
supply to the converter. Up to 16 units can be installed in one chassis. Unscrew and remove the cover of the
center connector before inserting the converter into the chassis. Refer to the operation manual of center chassis
KC-1300 for more information.
2.3 Applying Power
Before you begin the installation, check the AC voltage of your area. The AC power adapter which is used to
supply the DC power for the unit should have the AC voltage matching the commercial power voltage in your
area.
The AC Power Adapter Specifications
AC input power: AC power voltage of your area, options –
Rated AC 100-240V/50-60Hz DC7.5V0.5Amin.

Rated AC100V/50-60Hz DC7.5V0.5Amin.
Rated AC100V/50-60Hz DC5V1A
Steps to apply the power to the converters are:
1. Connect power adapter DC plug to the DC input jack located on the back of the converter before
connecting to the AC outlet.
2. To ensure against accidental disconnection, tie the DC cable with the cable tie located the back of the
converter.
3. Connect the power adapter to the AC outlet.
4. Check Power LED indication.

3. Optional Configuration Settings
The media converter provides additional configuration settings which are user-inaccessible. The settings are
built on the board inside the prod-uct case. The settings are provided for technical installers to adapt the
converter to fit some specific application needs.
3.1 User Inaccessible Jumpers
The setting jumpers are not accessible by users generally. For accessing these jumpers, the upper case must be
removed from the product. Re-moving the case must be performed by an authorized and experienced technical
person. The setting jumper block is located on the position shown below:
The setting functions are as follows:
JP1 Forwarding mode setting Open - Store-and-forward mode
Short - Smart-forward mode
JP2 802.3x function setting Open - Enable
Short - Disable
JP3 FX port duplex setting Open - Full duplex mode
Short - Half duplex mode
3.1.1 Forwarding Mode Setting JP1
The following table lists the forward method used in different TP to FX conversions:
JP1 Setting TP port to/from FX port Forward method
Store-and-forward 10BASE-T to 100BASE-FX Store and forward
100BASE-TX to 100BASE-FX Store and forward
Smart-forward 10BASE-T to 100BASE-FX Store and forward
100BASE-TX to 100BASE-FX Direct conversion
On smart-forward mode, the converter can change to direct conversion automatically when it detects same
speed on both TP port and FX port. Direct conversion method converts the signal between TP port and FX port

-19-
without storing the received packet on one port then forwarding to another port. The media converter operates
with the minimum latency.
Note:
1. In direct conversion, be sure both devices connected to the TP port and FX port have same duplex mode
for proper transmission.
2. In direct conversion, the 802.3x function is disabled and the media converter will not generate pause
frame, but just forwards the received pause frame directly from one port to another port.
3. In direct conversion, the media converter is not limited to the maximal length of the receiving packets.
3.1.2 802.3x Function Setting JP2
IEEE 802.3x function is the flow control method used for full duplex operation on TP port and FX port under
store and forward mode. This method uses pause frames for one port to stop further transmission from its link
partner.
3.1.3 FX Duplex Setting JP3
This setting is used to set the duplex mode of the FX port.
3.2 JP1-JP3 Factory Default Settings
The factory default settings for JP1, JP2, and JP3 are as follows:
JP1 Open Store-and-forward mode
JP2 Open 802.3x function is enabled
JP3 Open FX port full duplex
