Chapter 2: Overview: Compact Media Converter TP/BNC 50 Ohm
2. Overview: About the Compact Media Converter TP/BNC 50-ohm
With the Compact Media Converter TP/BNC, 50-ohm coax cable installations
become more accessible.
The Compact Media Converter TP/BNC is a 10 Mbps Ethernet Twisted Pair
to 50-ohm Coax cable (e.g. RG-59) Media Converter, that allows the
continued use of the already-installed 50-ohm analog cable, eliminating the
need to re-cable. As a low-cost, IEEE 802.3 single-conversion, 1U high,
standalone media converter, the Compact Media Converter TP/BNC
converter 10Base-T twisted pair to 10Base-2 thin coax and includes one RJ45 connector and one RG-49 BNC connector. Each Compact Media
Converter TP/BNC includes diagnostic LEDs and an internal 100/240 V AC
power supply.

Chapter 3 Installation
3. Install the Compact Media Converter TP/BNC 50-ohm
The Compact Media Converter TP/BNC converters come ready to install.
Deploy Compact Media Converter TP/BNC units in pairs, or connect a
Compact Media Converter TP/BNC converter to another Black Box
converter. To install a Compact Media Converter TP/BNC converter, first
make sure that the unit is placed on a flat surface. Attach the cables
between the Compact Media Converter TP/BNC and each device that will be
interconnect, the plug the unit into a reliable, filtered power source. Make
sure to connect the BNC port of the Compact Media Converter TP/BNC
converter only to 50-ohm coaxial cable.
When connecting an Ethernet cable to the Compact Media Converter
TP/BNC, make sure the cable corresponds to the Crossover/Pass-Through
switch. When using the Crossover cable, make sure the switch is out, in the
“X” setting. The switch can be pressed again to change the setting.

Chapter 4: Operation
4. Operation
4.1 Compact Media Converter TP/BNC 50-ohm Front Panel
The LEDs
Each Compact Media Converter TP/BNC features diagnostic LEDs. The
following illustration shows the location of the LEDs, and other features, on
the Compact Media Converter TP/BNC. The LED functions for the Compact
Media Converter TP/BNC are as follows:
TP LNK/ACT
BNC ACT
BNC COL
POWER
Glows yellow when a twisted pair link is established and flickers when
data is being received
Flickers green in normal operation indicating activity on the BNC port
Flickers red in normal operation indicating activity on the BNC segment
Flickers yellow when the unit is receiving power
4.2 Twisted Pair Crossover/Pass-Through Switch
The twisted pair port on the Compact Media Converter TP/BNC features a
push-button switch, located next to the twisted pair connector, for selecting a
crossover workstation connection or Pass-Through repeater/hub connection.
Select a Pass-Through connection by pressing the push-button IN. A
Crossover connection is selected when the push-button is OUT. If uncertain
whether a Crossover or Pass-Through connection is needed, set the pushbutton to the position that makes the TP LNK (link) LED glow.
4.3 BNC Port Termination
The Compact Media Converter TP/BNC features a 2-position, termination
switch (TERM) next to the BNC connector that allows a think coaxial
segment to be terminated at the port without the use of an external ‘T’
connector/terminator. (See the diagram in the Compact Media Converter
TP/BNC 50-ohm Front Panel section.)
If a ‘T’ connector/terminator is used, this switched must be set in the OFF
(disabled) position. Otherwise, double termination will result, which will
corrupt the signal.

Chapter 6: Fiber Optic Cleaning Guidelines
6. Fiber Optic Cleaning Guidelines
Fiber Optic transmitters and receivers are extremely susceptible to
contamination by particles of dirt or dust, which can obstruct the optic path
and cause performance degradation. Good system performance requires
clean optics and connector ferrules.
1. Use fiber patch cords (or connectors, if you terminate your own fiber) only
from a reputable supplier; low-quality components can cause many hard-todiagnose problems in an installation.
2. Dust caps are installed at Black Box to ensure factory-clean optical devices.
These protective caps should not be removed until the moment of connecting
the fiber cable to the device. Should it be necessary to disconnect the fiber
device, reinstall the protective dust caps.
3. Store spare caps in a dust-free environment such as a sealed plastic bag or
box so that when reinstalled they do not introduce any contamination to the
optics.
4. If you suspect that the optics have been contaminated, alternate between
blasting with clean, dry, compressed air and flushing with methanol to remove
particles of dirt.

Chapter 7: Electrostatic Discharge Precautions
7. Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product, add-in
modules or stand alone units, containing electronic components. Always
observe the following precautions when installing or handling these kinds of
products.
1. Do not remove unit from its protective packaging until ready to install.
2. Wear an ESD wrist grounding strap before handling any module or
component. If the wrist strap is not available, maintain grounded contact with
the system unit throughout any procedure requiring ESD protection.
3. Hold the units by the edges; do not touch the electronic components or gold
connectors.
4. After removal, always place the boards on a grounded, static-free surface,
ESD pad or in a proper ESD bag. Do not slide the modules or stand alone
units over any surface.
WARNING! Integrated circuits and fiber optic components
are extremely susceptible to electrostatic discharge damage.
Do not handle these components directly unless you are a
qualified service technician and use tools and techniques that
conform to accepted industry practices.
