10Base-T to 10Base-2 Converter
2 Hardware Description
Product Overview
The Converter was specifically designed to offer the
network designer the tools for migration from Coaxial
based Ethernet to UTP based Ethernet. Now,
migration or expansion of existing networks can be
achieved with minimum cost and complexity. The
Converter is completely transparent to the network so
the network performs exactly the way it did before only now it can migrate both UTP and coaxial
mediums.
Expands the Size of an Existing Network
Provides UTP/coaxial connectivity to Ethernet
segments, allowing for even further networking
expansion between extended nodes. Allows for the
quick and easy addition of coaxial segments to
existing 10Base-T networks.
Enhances Networking Distances
Connecting the Converter to UTP segments can
further extend distances of up to 185 meters for a total
segment length of 285 meters. The Converter can be
connected to an additional fiber converter for even
longer extensions.

10Base-T to 10Base-2 Converter
Cabling Flexibility
This unit allows network managers to put UTP cabling
anywhere within a network without retrofitting the
arrangement of the Ethernet network. Its sleek design
makes it easy to be installed in compact spaces or on
wall mount locations. Several converters can be
simultaneously installed by using a 19” Rack-mount
Chassis.

10Base-T to 10Base-2 Converter
Location
The location selected for installing the Converter may
greatly affect its performance. When selecting a site,
we recommend considering the following rules:
• Install the Converter in a fairly cool and
dry place. See Technical Specifications
for the acceptable temperature and
humidity operating ranges.
• Install the Converter in a location free
from strong electromagnetic field
generators (such as motors), vibration,
dust, and direct exposure to sunlight.
• Leave at least 10cm of space at the front
and rear of the unit for ventilation.
• Affix the provided rubber pads to the
bottom of the Converter for grip, and to
protect the case from scratching.

Installing Your Converter
10Base-T Connection
1. Make sure that the length for straight through
twisted pair cable between 10Base-T device (hub
or switch) and the Converter is no greater than
100 meters.
2. Connect one end of twisted pair cable to RJ-45
jack on the Converter and the other to the RJ-45
jack on the 10Base-T device.
3. Check the corresponding port LED on the
Converter to be sure that the connection is valid.
(Refer to LED chart in next section)

10Base-T to 10Base-2 Converter
10Base-2 Connection
To connect to an Ethernet using 10Base-2 cable, do
the following:
1. Attach the supplied BNC T-connector to the
Converter’s BNC connector.
2. Connect one end of a Thinnet (10Base-2) coaxial
cable to the BNC T-connector attached to your
Converter.
3. Connect the other end of the coaxial cable to the
BNC T- connector attached to the Ethernet device.
Note: If either your converter or the Ethernet device is
an end node, attach a BNC terminator to the open
connector on the BNC T-connector.

10Base-T to 10Base-2 Converter
Desktop Installation
Follow the instructions listed below to install the
Converter onto a desktop location.
1. Locate the Converter in a clean, flat and safe
position that has easy access to AC power.
2. Affix the provided rubber pads to the bottom of
the Converter for grip, and to protect the case
from scratching.
3. Apply power to the Converter. (The green PWR
LED on the front panel should light).
4. Connect cables from the network partner
devices to the ports on the front panel. (The
green LNK LED on the front panel associated
with the port should light).
This Converter can also be mounted on a vertical
surface. Simply use the underside of the unit as a
template to measure and mark out the position of the
holes on to the surface where the unit is to be
installed. Then use the two screws provided to mount
the Converter firmly in place.
Warning Please exercise caution when using power
tools. Also, install this unit away from damp or wet
locations, or in close proximity to very hot surfaces.
These types of environments can have a detrimental
effect on the converter and cables. An ideal locatio n is a
lightly cooled place such as a typical equipment room.
-12-
10Base-T to 10Base-2 Converter
Powering On Unit
The Converter uses external power supply 12V DC @
0.5A 50~60 Hz.
1. Insert the power cable plug directly into the
receptacle located at the back of the device.
2. Plug the power adapter into an available socket.
3. Check the front-panel LEDs as the device is
powered on to verify that the Power LED is lit. If
not, check that the power cable is correctly and
securely plugged in.
Note: For International use, you may need to change the AC
power adapter cord. You must use a power cord set that
has been approved for the receptacle type and electrical
current in your country.

Appendix A
Mini Converter Chassis
The Chassis was developed to accommodate just one
media converter. The Chassis provides AC or DC
power and protection for converter units. Now,
network designers can plan their Ethernet, Fast
Ethernet, ATM, or Gigabit networks without having to
worry about the power source. Furthermore, its unique
sizes allows it to be installed in locations where space
is limited.
Features
• Adds fiber connectivity to otherwise copper based
networks
• Supports 10/100/1000Base, copper, fiber,
single/multi-mode converters with, RJ-45, ST, SC,
MT-RJ, VF-45, LC, WDM connectors
• Accommodates one media converter
• Suitable for all size of networks in all locations
• Suitable as stand-alone or in 19" 4/12-slot rack-
mounted converter chassis or the single slot mini
chassis (with internal power supply)
• Provides internal AC or DC switching power
supply
• Optional external redundant power adapter

10Base-T to 10Base-2 Converter
Affixing Brackets
We have supplied 2 special brackets that easily
attaches to the Converter. This allows for the secure
placement of the converter into the Chassis. It also
seals off the front of Chassis and allows it to function
correctly.
Step 1 Using a Phillips screwdriver, remove two screws from
the side panels on the converter.
Step 2 Place the converter and brackets on a flat horizontal
surface as illustrated above. Secure the brackets by
replacing the screws.
Ensure that the rails are flush-mount with the underside of the
converter. The converter is now ready for loading into the
Chassis.
-16-
10Base-T to 10Base-2 Converter
Installing the Converter
Once the Converter has been attached to the bracket,
it can be installed into the Chassis. Special care must
be taken to ensure the correct mating of the power
connector. Align the Converter so that it fits between
the upper and lower guide rails.
Always ensure that the converter power socket is
positioned at the base of the Chassis. Never force the
Converter into the Chassis - check power socket position
and alignment
.
