1. Introduction
The 10/100 ridging converter provides two 10/100M ps- ased
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 fi er connection. It provides a cost-effective solution
for ridging etween 10 and 100M ps networks, extending distance
for 100M ps networks, and media conversion for UTP ca le and
fi er ca le. Three models are availa le for multimode ST fi er, mul-
timode SC fi er, and single mode SC fi er connections respectively.
Both switched ports feature NWay auto-negotiation capa ility y
which they can negotiate the speed and duplex mode with the con-
nected device.
The following figure illustrates the front and rear view of the switch:

2. Installation
Unpacking
Check to see that you have everything efore you start the installation.
 Installation guide
 The unit
 One AC power adapter for the switch
Installation
The switch can e placed on a desktop as a stand-alone unit. It also
can e mounted on a magnetic-sensitive metal surface with its ru -
er magnet stand located on the ottom of the unit.

-5-
Checking AC Power
One AC power adapter is contained in the product package. Before
you egin 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 elow:

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 elow:
Port 1, Port 2 SW1 Off Auto-negotiation is enabled.
On Auto-negotiation is disabled.
Port 1, Port 2 SW2 Off 100Mbps is used. (When SW1 = On)
On 10Mbps is used. (When SW1 = On)
Port 1, Port 2 SW3 Off Full-duplex is used. (When SW1 = On)
On Half-duplex is used. (When SW1 = On)
Port 2 only SW4 Off Fiber connector is disabled.
On Fiber connector is enabled.
Factory Defaults
SW1 Off Auto-negotiation is enabled.
SW2 Off 100Mbps
SW3 Off Full-duplex
SW4 On Fiber connector is enabled.

-7-
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 ena les the port to negotiate a common
operation mode with the device connected at the remote end of the
link ca le. The common operation mode includes connection speed
and duplex type. When an operation mode is accepted y the re-
mote device, the mode is used for the data transfer etween the port
and the connected device.
TP Ports
In order to provide flexi le connection to a remote device using a
popular straight-through UTP ca le, 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

UTP Connections
The following figure shows a UTP connection from TP port to
another device via a straight-through UTP ca le. 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
10/100MNWayNICcard AUTO 100BASE-TX, full-duplex
10M Ethernet device Non-auto 10BASE-T, half-duplex
* Note that all hu 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 ca le for the connection, make sure
the MDI-X to MDI connection rule is followed.

-9-
Fiber Port and Fiber Connection
When connecting to a 100BASE-FX device using fi er ca le, make
sure Port 2 SW4 is set to ON position and TX-to-RX connection
rule is followed.
Since the fi er connector does not support auto-negotiation func-
tion, it is recommended to set SW1 to ON position for the fi er
connection. If SW1 is set to OFF, it operates on half-duplex mode.
Fiber Cables
The required fi er ca le for the connection are:
Model /T model /C model /S series
Fibermode Multimode Multimode Singlemode
Wavelength 1300µm 1300µm 1300µm
Connectors ST SC SC
Multimodefiber: 50/125, 62.5/125, 85/125, 100/140µm
Single mode fiber: 9/125µm
The maximum distance connecting to a 100BASE-FX device de-
pends on the device connected and the duplex mode used for the
connection as follows:
