1. Introduction

The 10/100 bridging converter provides two 10/100Mbps-based
Fast Ethernet switch ports. Port 1 features one 10/100M UTP
connection and Port 2 features either one 10/100M UTP connection
or one 100M fiber connection. It provides a cost-effective solution
for bridging between 10 and 100Mbps networks, extending distance
for 100Mbps networks, and media conversion for UTP cable and
fiber cable. Three models are available for multimode ST fiber, mul­timode SC fiber, and single mode SC fiber connections respectively.

Both switched ports feature NWay auto-negotiation capability by
which they can negotiate the speed and duplex mode with the con­nected device.

The following figure illustrates the front and rear view of the switch:

2. Installation

Unpacking

Check to see that you have everything before you start the installation.

 Installation guide
 The unit
 One AC power adapter for the switch

Installation

The switch can be placed on a desktop as a stand-alone unit. It also
can be mounted on a magnetic-sensitive metal surface with its rub­ber magnet stand located on the bottom of the unit.

-4-

Checking AC Power

One AC power adapter is contained in the product package. 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 specifications of the AC power adapter are:

 AC input power: AC power voltage of your area

 DC output power:+12 VDC 800mA min.

 DC plug type:

The power socket for the AC power adapter is located on the rear of
the unit as shown below:

3. Making Network Connections

Two Switched Ports

Two switched ports are located on the front panel.

Configuration Switches

On rear panel, Port 1 and Port 2 have individual configuration switches
as shown below:

Port 1, Port 2 SW1 Off Auto-negotiation is enabled.
Port 1, Port 2 SW2 Of f 100Mbps is used. (When SW1 = On)
Port 1, Port 2 SW3 Off Full-duplex is used. (When SW1 = On)
Port 2 only SW4 Off Fiber connector is disabled.

On Auto-negotiation is disabled.
On 10Mbps is used. (When SW1 = On)
On Half-duplex is used. (When SW1 = On)
On Fiber connector is enabled.

Factory Defaults

SW1 Of f Auto-negotiation is enabled.
SW2 Off 100Mbps
SW3 Off Full-duplex
SW4 On Fiber connector is enabled.

-6-

Important Note:

If any change are made to the configuration switch
settings, the power to the unit must be turned off and
turned on again before the changes can take effect.

The auto-negotiation mode enables the port to negotiate a common
operation mode with the device connected at the remote end of the
link cable. The common operation mode includes connection speed
and duplex type. When an operation mode is accepted by the re­mote device, the mode is used for the data transfer between the port
and the connected device.

TP Ports

In order to provide flexible connection to a remote device using a
popular straight-through UTP cable, each port features two types
of RJ-45 jacks.

Jack Function

1X MDI-X jack for Port #1
1 MDI jack for Port #1
2X MDI-X jack for Port #2
2 MDI jack for Port #2

The pin assignments of the jacks are defined as follows:

Pin MDI-X Jacks MDI Jacks

1 RX data + TX data +
2 RX data - TX data ­ 3 TX data + RX data +
6 TX data - RX data ­4,5,7,8 NC NC

-7-

UTP Connections

The following figure shows a UTP connection from TP port to
another device via a straight-through UTP cable. When TP port of
Port 2 is used, make sure Port 2 SW4 is set to OFF position.

Depending on the configuration switch setting, the operating modes
used for connecting to different devices are shown as follows:

Connected Device SW1 setting Port Operation Mode

10M Ethernet hub AUTO 10BASE-T, half-duplex
100M Fast Ethernet hub AUTO 100BASE-TX, half-duplex
10/100M dual speed hub AUTO 100BASE-TX, half-duplex
10/100M NWay switch AUTO 100BASE-TX, full-duplex
10/100M NWay NIC card AUTO 100BASE-TX, full-duplex
10M Ethernet device Non-auto 10BASE-T, half-duplex

* Note that all hub devices are half-duplex devices.

Compliant UTP Cables

Connection UTP Cable Type Maximum Length

10BASE-T Cat. 3, 4, or 5 100 meters

100BASE-TX Cat. 5 100 meters

When using a straight-through cable for the connection, make sure
the MDI-X to MDI connection rule is followed.

-8-

Fiber Port and Fiber Connection

When connecting to a 100BASE-FX device using fiber cable, make
sure Port 2 SW4 is set to ON position and TX-to-RX connection
rule is followed.

Since the fiber connector does not support auto-negotiation func­tion, it is recommended to set SW1 to ON position for the fiber
connection. If SW1 is set to OFF, it operates on half-duplex mode.

Fiber Cables

The required fiber cable for the connection are:

Model /T model /C model /S series

Fiber mode Multimode Multimode Single mode

Wavelength 1300µm 1300µm 1300µm

Connectors ST SC SC

Multimode fiber: 50/125, 62.5/125, 85/125, 100/140µm

Single mode fiber: 9/125µm

The maximum distance connecting to a 100BASE-FX device de­pends on the device connected and the duplex mode used for the
connection as follows:
