PC Media Converter™ is a fixed-configuration, IEEE 802.3 single-
conversion PC Media Converter Adapter that is designed to convert
RJ-45 (10Base-T twisted pair), BNC (10Base-2 thin coax), ST or SC
(10Base-FL 850 nm multi-mode, 1300 nm multi-mode or single-mode)
fiber. PC Media Converter can be mounted in any PC with a standard
ISA or PCI slot. All versions of PC Media Converters include diagnostic
LEDs for each port and a 4-pin peripheral power supply connector.
The following PC Media Converter versions are available:
UTP/FO — 10Base-T twisted pair/10Base-FL 850 nm multi-mode
fiber; includes one RJ-45 connector and one pair ST
(LE6601C) or SC (LE6602C) connectors
UTP/FO 1300 — 10Base-T twisted pair/10Base-FL 1300 nm multi-
mode fiber; includes one RJ-45 connector and one pair
ST (LE6603C) or SC (LE6604C) connectors
UTP/FO-SingleMode — 10Base-T twisted pair/10Base-FL 1300 nm
single-mode fiber; includes one RJ-45 connector and one
pair ST (LE6605C) or SC (LE6606C) connectors
UTP/FO-SingleMode/PLUS — same as above with higher power
budget; includes one pair ST (LE6607C) or SC (LE6608C)
connectors
UTP/BNC — 10Base-T twisted pair/10Base-2 thin coaxial; includes
one RJ-45 connector and one BNC connector (LE6609C)
Installing PC Media Converter
To install PC Media Converter, turn off the power on your PC and
remove the cover. Find an empty ISA or PCI slot and align PC Media
Converter in the slot. Then
mount PC Media Converter by
screwing its bracket to the
computer casing.
NOTE: PC Media Converter does
not plug into the mother board.
Also, make sure PC Media
Converter does not extend past
the edge of your case.
Attach the keyed mini-power
connector to PC Media
Converter. Attach the male end of the “Y” connector to a standard size
power connector in your computer. Replace the cover. Attach the
cables between PC Media Converter and the devices that will be
interconnected
.
NOTE: PC Media Converter only needs power from the computer; no
additional power source is necessary.
After installation, you can configure PC Media Converter for the
following features, depending on the requirements of your installation:
• Crossover/pass-through connection on the twisted pair port
• BNC Port Termintation
• FiberAlert
• LinkLoss
Twisted Pair Crossover/Pass-Through Switch
Each twisted pair port on PC Media Converter has one RJ-45 connector
for a single shielded or unshielded twisted pair link segment, and features
a push-button, located next to the TP connector, for selecting a crossover
workstation connection or pass-through repeater/hub connection. To
select a pass-through connection, simply press the push-button IN. A
crossover connection is selected when the push-button is OUT.
BNC Port Termination
PC Media Converter UTP/BNC features a 2-position switch next to the
BNC connector that allows a thin coaxial
segment to be terminated at the port without
an additional ‘T’ connector and terminator.
If PC Media Converter UTP/BNC is attached
to a mid-point of a thin Ethernet segment,
attach a ‘T’ connector to the BNC port.
Termination must be OFF (disabled).
Termination is disabled when the toggle is in the left position.
If a thin Ethernet segment is to be terminated at the PC Media
Converter UTP/BNC, attach the cable directly to the BNC connector and
set the termination to ON (enabled – factory default). Toggle the switch
to the ON position to enable termination.
Troubleshooting with LinkLoss and FiberAlert
LinkLoss and FiberAlert are advanced troubleshooting features that can
help you use your PC Media Converter to locate “silent failures” on your
network. It is vital that you understand exactly how FiberAlert and
LinkLoss work and how they will react in your network configuration
before attempting to use your PC Media Converter.
