1.4 Special Functions
AutoMDI/MDI-XFunction
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.
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 negotia-
tion process for the speed and duplex configuration with the connected
device automatically when each time a link is being established.
Far End Fault Function
The FX ports are 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 con-
verter to report a fiber link fault even when a link failure occurred on
transmitting fiber cable.

2.3 Mounting on a Plane Surface
An optional mounting bracket, as shown below is also available for mount-
ing the device on a plane surface such as a wall, a wood board, or a metal
plate in an industrial enclosure.
To mount the device on a plane surface, the steps are:
1. Clamp the bracket into the device and align the bracket with the
bottom surface of the device and screw it on the converter firmly as
shown below:
-19-
2. Mount and screw the device on the target surface. The final
dimension after bracket installation is also shown below:
Make sure that there are proper heat dissipation from and adequate ven-
tilation around the device. Do not place heavy objects on the device.

2.4 Applying Power
The product provide two types of power interfaces, terminal block and DC
power jack for receiving DC power input from external power supply.
DC Power Input Specification
Operating Voltage
+7~+30VDC
Power Consumption
Max. 3.0W@30VDC
DC Power Terminal Block
Connectors
Screw-type Terminal block (2 sets)
Pin Assignments
DC1+ - Positive (+) Negative (-) terminals
DC2+ - 2nd Positive (+) Negative (-) terminals
24~12AWG(IEC0.5~2.5mm2)
Power wires
The steps to install power wires to the terminal block are:
1. Loose the terminal screw to open the contact for power wire
insertion. Insert power wire into the contact.
2. Screw the terminal and make sure power wire is fixed securely.
-21-
DC2 + and DC2 - can be installed with another power-pair for delivering the
main power input to next converter in a cascading way.
Note: Only up to four device units can be cascaded to receive power
from one main power input source.
DC Power Jack
Connector:
Jack D 6.3mm
D 2.0mm
AC Power Adapters: Optional commercial rated adapters are available
for purchasing.
Rated AC120V/60Hz DC7.5V 1A
Rated AC230V/50Hz DC7.5V 1A
Rated AC100V/50-60Hz DC7.5V 1A
Rated AC240V/50Hz DC7.5V 1A
Steps to apply the power to the device are:
1. Connect power adapter DC plug to the DC power jack of the
converter before connecting to the AC outlet.
2. Connect the power adapter to the AC outlet.
Note: 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.

connecting to a link partner port which is not auto-negotiation capable.
Refer to section 2.5 for details.
3.1.2 802.3x Function Setting SW4
IEEE 802.3x function is the flow control method used for full duplex op-
eration on the TP port and FX ports 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 Port Duplex Settings SW5 SW6
This settings are used to set the duplex mode of the FX1 port and FX2
port individually. It is recommended to use full duplex mode for FX con-
nection unless its link partner is a fixed half duplex device. Half duplex
mode will shorten the connection distance. The following table lists the
maximum MMF cable length connecting to different devices:
