ABOUT MCBASIC TX/FX
McBasic TX/FX is an IEEE 802.3 media converter that performs a single
conversion between 100Base-TX twisted-pair and 100Base-FX multi-mode or
single-mode fiber. Single-strand fiber versions are also available. The unit
includes one RJ-45 connector for the twisted-pair port and either ST, SC, MT or
LC connectors for the fiber port. McBasic TX/FX is a 1U high, standalone unit
that includes diagnostic LEDs for each port and a universal (100/240 VAC)
power supply.
NOTE: All versions of the 100 Mbps Fast Ethernet McBasic media converter, including
850 nm multi-mode fiber (TX/SX) and single-strand versions (TX/SSFX), will be referred
to as McBasic TX/FX throughout this manual except where differences must be
indicated.
NOTE: Some options require items that are sold separately, available from B+B
SmartWorx.
INSTALLING MCBASIC TX/FX
McBasic TX/FX comes ready to install; make all configurations after installation.
To install McBasic TX/FX, first make sure that the unit is placed on a suitable
flat surface. Attach the cables between the McBasic TX/FX and each device
that will be interconnected; then plug the unit into a reliable, filtered power
source.
NOTE : INSTALLATION TIP - Since single-strand fiber products use optics that transmit and receive
on two different wavelengths, single-strand fiber products must be deployed in pairs, or connect two
compatible B+B SmartWorx single-strand fiber products. The two connected products must also have
the same speed and distance capabilities (i.e. both are single-mode [20km] or both are single/PLUS
[40km]).
CONFIGURING MCBASIC TX/FX
McBasic TX/FX features an 8-position DIP
Switch for configuring the unit after
installation. Access this switch through a cut-
out in the bottom of the unit. After configuring
the DIP Switch, power down the unit and then
power up again for changes to take effect.
Default settings for the following features are
shown at right.

AUTO NEGOTIATION ON MCBASIC TX/FX
McBasic TX/FX includes Auto Negotiation. When Auto Negotiation is enabled
(default), the media converter negotiates as a 100 Mbps Full-Duplex device. If
the device the McBasic TX/FX is connected to can operate at 100 Mbps Full-
Duplex, a link will be established.
If the twisted-pair port on the other device does not have the ability to Auto
Negotiate, or if a 100 Mbps Half-Duplex connection is desired, Auto Negotiation
on McBasic TX/FX must be disabled. Half- and Full-Duplex settings must be
manually set and match on both devices to which McBasic TX/FX is connected.
The diagram below shows a typical application, followed by a table with three
possible configurations:

Twisted-pair Crossover/Pass-Through Connections
Whether using crossover or straight-through CAT5 twisted-pair cabling,
McBasic TX/FX will support both types of connections by one of the following
methods:
DSW#1 Auto Negotiation (AN) If set to default ON, the media converter will
negotiate with the link partner to the speed
and duplex mode. If set to OFF, FORCE
mode is available, and the link partner must
be set to FORCE mode as well.
DSW#2 (reserved)
DSW#3 MDI/MDIX To manually configure McBasic TX/FX for a
pass-through (MDI) or crossover (MDI-X)
connection, move the Auto MDI/MDI-X
Switch 4 to OFF; then move Switch 3 to the
desired connection type: MDI=OFF and
MDI-X=ON. If unsure of the type of
connection, set the DIP Switch to a position
that makes the twisted-pair LNK (link) LED
glow.
DSW#4 Auto MDI/MDIX McBasic TX/FX includes AutoCross, a
feature that automatically selects between a
crossover workstation or pass-through
connection, depending on the connected
device. To enable AutoCross, move the
Auto MDI/MDI-X switch to the ON position.
DSW#5 TXLL TX LinkLoss - diagnostic feature to
troubleshoot a loss on the copper port.
DSW#6 FX LL FX LinkLoss - a diagnostic feature to
troubleshoot a loss on the fiber port.
DSW#7 FA FiberAlert - a diagnostic feature to
troubleshoot the loss of one strand of fiber.
DSW#8 FA Pulse Pulsing FA - a diagnostic feature to
troubleshoot the loss of one strand of fiber;
Pulse FA can be enabled on both media
converters.

ABOUT FIBERALERT & LINKLOSS
McBasic TX/FX comes with the following troubleshooting features:
• FX LinkLoss (a.k.a. "Fiber LinkLoss" or "LinkLoss")
• TX LinkLoss (a.k.a. "Twisted-pair LinkLoss” or "Reverse LinkLoss”)
• FiberAlert (including Pulsing FiberAlert)
LinkLoss and FiberAlert are advanced troubleshooting features that can help
locate "silent failures" on the network. However, it is vital to understand exactly
how FiberAlert and LinkLoss work, and how they will react in the network
configuration, before attempting to install the enclosed module(s).
**WARNING**
Installing modules without understanding the effects of LinkLoss and FiberAlert can cause perfectly
functioning units to appear flawed or even non-functional.
Link Integrity
During normal operation, link integrity pulses are transmitted by all point-to-
point Ethernet devices. When an B+B SmartWorx media converter receives
valid link pulses, it knows that the device to which it is connected is up and
sending pulses, and that the copper or fiber cable coming from that device is
intact. The appropriate “LINK” LED is lit to indicate this. The B+B SmartWorx
media converter also sends out link pulses from its copper and fiber
transmitters, but normally has no way of knowing whether the cable to the other
device is intact and the link pulses are reaching the other end. FiberAlert and
LinkLoss allow this information to be obtained from the fiber, even when
physical access to a remote device (and its link integrity LED) is not available.
LinkLoss
FX LinkLoss is a troubleshooting feature. When a fault occurs on the fiber
segment of a conversion, FX LinkLoss detects the fault and passes this
information to the twisted-pair segment. If a media converter is not receiving a
fiber link, FX LinkLoss disables the transmitter on the media converter's
twisted-pair port. This results in a loss of link on the device connected to the
twisted-pair port.

McBasic TX/FX

TX LinkLoss
TX LinkLoss is a troubleshooting feature. When a fault occurs on the twisted-
pair segment of a conversion, TX LinkLoss detects the fault and passes the
information to the fiber segment. If a media converter is not receiving a twisted-
pair link, TX LinkLoss disables the transmitter on the media converter's fiber
port. This results in a loss of link on the device connected to the fiber port.
FiberAlert
FiberAlert minimizes problems
associated with the loss of one
strand of fiber. If a strand is
unavailable, the B+B device at
the receiver end notes the loss
of link. The device will stop
transmitting data and the link
signal until a signal or link pulse
is received. The result is that
the link LED on BOTH sides of
the fiber connection will go out,
indicating a fault somewhere in
the fiber loop. Using FiberAlert,
a local site administrator is
notified of a fault and can
quickly determine where a cable
fault is located.

NOTE : INSTALLATION TIP - Enable FiberAlert on only ONE side of a media conversion; enabling it on both sides will
keep both transmitters off indefinitely. To enable FiberAlert on BOTH sides of the conversion, Pulsing FiberAlert on one unit
must also be enabled. B+B SmartWorx recommends enabling Pulsing FiberAlert on ONE side.
NOTE : FiberAlert is not available/applicable on single-strand fiber versions of McBasic.

Pulsing FiberAlert
Use Pulsing FiberAlert in the following two situations:
1. When connecting two McBasic TX/FX units (or McLIM TX/FX modules) with FiberAlert
enabled.
2. When connecting one McBasic TX/FX with FiberAlert enabled and one McBasic
10/100 unit with Link Fault Detection (LFD) enabled.
NOTE : Pulsing FiberAlert may be useful when connecting McBasic TX/FX to another manufacturer’s product that has a
similar feature to FiberAlert. Please refer to the McBasic 10/100 Installation Guide for more information on LFD.

TROUBLESHOOTING - INSTALLATION
• During installation, first test the fiber and twisted-pair connections with all
troubleshooting features disabled; then enable features, if desired, just before final
installation. This will reduce the features’ interference with testing.
• When working with units where the features cannot be disabled, BOTH the twisted-
pair and fiber connections must be established before the link LEDs will light.
• To test a media converter by itself, have an appropriate fiber patch cable, then follow
these steps to test:
Step 1
Connect the media converter to the twisted-pair device with a
twisted-pair cable.
Step 2
Loop a single strand of fiber from the Transmit port to the
Receive port of the media converter.
Step 3
Verify that both twisted-pair and fiber link (see LED Operation)
are on the media converter.
• Make sure to use the appropriate twisted-pair cable, and have the crossover/pass-
through switch set correctly, if the media converter does not include AutoCross.
• If using a high powered device (which is designed for long distance installations) for a
short distance installation, the fiber transmitters may overdrive the receivers and cause
data loss. If this is the case, an optical attenuator may be need to be added to the
connection.

ELECTROSTATIC DISCHARGE (ESD) 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 units by the edges; do not touch the electronic components or gold connectors.
4. After removal, always place 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.
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-to-diagnose problems in an installation.
2. Dust caps are installed at the factory 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.
