1. Introduction
The industrial rated KSD-103 Fast Ethernet switch series supports three switching-base segment
communications and benefit the following applications and make fiber deployment easier :
ꢀ Copper to fiber bridging converter
ꢀ Multimode fiber to single mode fiber bridging converter
ꢀ Fiber cable extender
ꢀ Cascaded fiber networking
Depending on the types of the network ports, two different model series are defined as follows:
Model
Copper Port (RJ-45)
2 ports
Fiber Port
1 port
KSD-103-A

2.5 Applying Power
The power specifications of the device are:
Operating Voltage
+7 ~ +50VDC
Power Consumption
4W max. @+50VDC
Using Terminal Blocks
Either DC1 interface or DC2 interface can be used to receive DC power from an external power
system. Or, DC2 also can be used to deliver the power received on DC1 to next device in cascading
way.
DC1
DC1
DC2
DC2
+Vdc Positive (+) terminal
-Vdc Negative (-) terminal
+Vdc Positive (+) terminal
-Vdc Negative (-) terminal
Three 2P terminal plugs are provided together with the device. Two of the three plugs are used for
DC1 and DC2 interfaces respectively. The plug is shown below:
2
Power wires: 24 ~ 12AWG (IEC 0.5~2.5mm )
Install the power source wires with the plug properly. Screw the wire with plug securely. Then, plug in
DC1 contacts.

If cascading the power to next device is needed, install the power wires and plug for another switch.
Then, use DC2 contacts.
Note: Only up to four device units can be cascaded to receive power from one main power input
source.
Using DC Power Jack
DC Jack Connector: D 6.3mm
D 2.0mm
AC Power Adapters: Optional power adapters are available for purchasing.
Connect power adapter DC plug to the DC power jack of the converter before connecting to the AC
outlet. 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 that
is used to supply the DC power for the unit should have the AC voltage matching the
commercial power voltage in your area.
2.6 Failure Alarm Relay Output
The device provides a relay output to report failure events to a remote alarm monitoring system. The
replay output is provided with two contacts labeled PF+ and PF- in the terminal block interface.

3. Making LAN Connections
3.1 Making Copper Port (RJ-45) Connections
The copper ports support the following connection types and distances:
Network Cables
10BASE-T:
2-pair UTP Cat. 3,4,5 , EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair / 4-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters
Auto MDI/MDI-X Function
This function allows the 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. No matter a straight
through cable or crossover cable connected, the ports can sense the receiving pair automatically and
configure self to match the rule for MDI to MDI-X connection. It simplifies the cable installation by
using only straight-through cables.
Auto-negotiation Function
The ports are featured with auto-negotiation function and full capability to support connection to any
Ethernet devices. The port performs a negotiation process for the speed and duplex configuration with
the connected device automatically when each time a link is being established. If the connected device
is also auto-negotiation capable, both devices will come out the best configuration after negotiation
process. If the connected device is incapable in auto-negotiation, the switch will sense the speed and
use half duplex for the connection.
3.2 Making Fiber Connections
The fiber ports operate on 100Mbps and full duplex. For different fiber connections, several alternative
models can be selected for different fiber connections. The following figure illustrates a connection
example between two SC fiber ports:
A variety of fiber options and the associated optical specifications are provided as listed in
Appendix-1.
