1. Introduction
The KSD-800 series is 8-port full wire speed Fast Ethernet switches for industrial applications. Depending on the fiber connectivity, the series is provided in three types of configuration as follows:

800-1xxx
800-2xxx

10/100TX TP Ports
8 ports

The switches provide the following advantages:
Plug and PlayThe switches provide eight 10/100TX copper ports for connections to Ethernet devices or 100Mbps
Fast Ethernet devices. With the featured auto-negotiation function, the switches can detect and configure the connection speed and duplex automatically. The switches also provide auto MDI/MDI-X function, which can detect the connected cable and switch the transmission wire pair and receiving pairautomatically. This auto-crossover function can simplify the type of network cables used.
Selectable Copper/Fiber Connections
The 100FX fiber ports can support 100Mbps fiber connection using optic fiber cable and extend a
network connection up to several kilometers via fiber cables. The 100TX ports are designed to sharethe same switched ports with the associated 10/100TX copper ports. It means the switched port supports dual network media types, either copper cable or fiber cable.
Designed for Industrial Applications
For industrial environment, the switches are designed with the following enhanced features:

 High and wide operating Temperature
 Wide operating voltage range for DC power input Power input interface: Screw terminal block and DC jack for adapter
 Relay output for device power failure alarm DIN rail mounting support for industrial enclosure Panel mounting support for industrial enclosure-5-

2.1 Unpacking
The product package contains:• The switch unit
• One DIN-rail mounting kit• One product CD-ROM

2.2 Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe thefollowing precautions.

• Do not service any product except as explained in your system documentation.
• Opening or removing covers may expose you to electrical shock.
• Only a trained service technician should service components inside these compartments.
• If any of the following conditions occur, unplug the product from the electrical outlet and replace
the part or contact your trained service provider:- The power cable, extension cable, or plug is damaged.
- An object has fallen into the product.
- The product has been exposed to water.
- The product has been dropped or damaged.
- The product does not operate correctly when you follow the operating instructions.
• Do not push any objects into the openings of your system. Doing so can cause fire or electric
shock by shorting out interior components.
• Operate the product only from the type of external power source indicated on the electricalratings label. If you are not sure of the type of power source required, consult your service
provider or local power company.

-14-

2.3 DIN-Rail Mounting
In the product package, a DIN-rail bracket is provided for mounting the switch in a industrial DIN-rail
enclosure.
The steps to mount the switch onto a DIN rail are:
1. Install the mounting bracket onto the switch unit as shown below:

2. Attach bracket to the lower edge of the DIN rail and push the unit upward a little bit until thebracket can clamp on the upper edge of the DIN rail.
3. Clamp the unit to the DIN rail and make sure it is mounted securely.

-15-

2.4 Panel Mounting
The switches are provided with an optional panel mounting bracket. The bracket support mounting theswitch on a plane surface securely. The mounting steps are:
1. Install the mounting bracket on the switch unit.

2. Screw the bracket on the switch unit.

-16-

3. Screw the switch unit on a panel. Three screw locations are shown below:-17-2.5 Applying PowerThe power specifications of the switch are:Operating Voltage
Power Consumption+7 ~ +30VDC
Max. 7.3W @30VDC

The switch provides two types of power interfaces, terminal block and DC power jack for receiving DC
power input from external power supply.

Using Terminal Blocks
Either DC1 interface or DC2 interface can be used to receive DC power from an external powersystem. Or, DC2 also can be used to deliver the power received on DC1 to next switch in cascading
way.
DC1 +

Vdc Positive (+) terminal

DC1 -Vdc Negative (-) terminal

DC2 +Vdc Positive (+) terminal

DC2 -Vdc Negative (-) terminal

Three 2P terminal plugs are provided together with the switch. Two of the three plugs are used for
DC1 and DC2 interfaces respectively. The plug is shown below:

Power wires : 24 ~ 12AWG (IEC 0.5~2.5mm2)
Install the power source wires with the plug properly. Then, plug in DC1 contacts. If cascading thepower to next switch 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 fromone main power input source.

-18-

Using DC Power Jack
When an external power system is not available, the switch provides a DC jack to receive power fromtypical AC-DC power adapter alternatively.

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
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.

2.6 Power Failure Relay Output
The switch provides a relay output to report power failure event to a remote alarm monitoring system.
The replay output is provided with two contacts in the terminal block next DC2 interface.

Use the provided 2P terminal plug for signal wiring and plug into the PF+/- contacts. The function isdesigned as :Power is normal
Power failure

PF+ contact is shorted with PF- contact.
PF+ contact is disconnected with PF- contact.

Note: Be sure the voltage applied on PF+/- contacts is within the specification of
30VDC/1A max. or 120VAC/0.5A max.

-19-

2.7 Reset Button

The reset button is used to perform a hardware reset to the switch. It is not used in normal cases andcan be used for diagnostic purpose. If any network hanging problem is suspected, it is useful to push the
button to reset the switch without turning off the power. Check whether the network is recovered.

2.8 Selecting UTP or Fiber

If the switch is equipped with FX7 port or FX8 port, it is required to select the media type to be used forthe switched Port 7 and Port 8. Set the setting SW which is located on bottom panel to make theselection.

The 10/100TX ports supports 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 UTP Cat. 5, EIA/TIA-568B 100-ohm

Link distance:

Up to 100 meters

The ports are equipped with auto MDI/MDI-X function and auto-negotiation function for the UTP
connection.
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 is connected, the ports can sense the receiving pair automatically andconfigure itself to match the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
The ports are featured with auto-negotiation function and full capability to support connection to :• Auto-negotiation devices• Auto-negotiation incapable 10BASE-T devices• Auto-negotiation incapable 100BASE-TX devices
It 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 forthe connection.

2.10 Making Fiber Connections

FX7 port and FX8 port operate on 100Mbps and full duplex.
The following figure illustrates a connection example between two fiber ports:

Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
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 (FarEnd 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 switch to report afiber link fault even when a link failure occurred on transmitting fiber cable.
