McBasic 10/100
Installation Guide
McBasic 10/100 is a low-cost, preconfigured, IEEE 802.3 singleconversion MediaConverter that is designed to convert between 10Base-T
twisted pair and 10Base-FL multi-mode or single-mode fiber or between
100Base-TX twisted pair and 100Base-SX multi-mode fiber or 100Base-FX
single-mode fiber.
McBasic 10/100 is a 1U high, stand-alone unit that includes diagnostic
LEDs for each port and a universal (100/240 VAC) power supply. McBasic
10/100 includes one RJ-45 connector and one pair of ST or SC connectors
or one VF fiber connector.
Installing McBasic 10/100
McBasic 10/100 comes ready to install. The only adjustments that may
need to be made after installation are:
l
Configuring the unit for its mode of operation.
l
Setting the twisted pair port for a crossover workstation or pass-through
repeater/ hub connection.
To install McBasic 10/100, first make sure that the unit is placed on a
suitable flat surface, and leave some space at the back of the unit to
accommodate the exhaust fan. Attach the cables between the McBasic
10/100 and each device that will be interconnected, then plug the unit into
a reliable, filtered power source.
NOTE: All network cables must be connected for link LEDs to glow.
The following diagram shows the faceplate on McBasic 10/100. Regardless of the type of fiber connector(s), the LEDs remain the same. More on
the specific functions of the LEDs can be found later in this guide.
Configuring McBasic 10/100
McBasic 10/100 features an 8-position
Dip switch for configuring the unit. This
switch is accessed through a cut-out in the
bottom of the unit.
The following table provides simplified
definitions of the function of each switch.
More detailed information follows.
Note: Dip switches 1, 2, 3, 7 and 8 are reserved for future use and are
configured at the factory; DO NOT change these switches.
McBasic 10/100 Modes of Operation
The McBasic 10/100 MediaConverter features three possible modes of
operation: PNP/Transparent mode, Force 10 mode and Force 100 mode.
Your McBasic 10/100 should be configured for one of these modes (factory
default is PNP/Transparent mode).
nn
PNP/Transparent mode, also known as Auto-Negotiation or
plug-and-play mode, is the mode most ideally suited for the
McBasic 10/100. In this mode, the converter will optimally and
automatically configure for speed (10 or 100 Mbps) and duplex
(Half or Full) depending on the capabilities of the end stations.
To enable PNP/Transparent mode, Dip switch 4 must be in the
ON position (factory default). To disable PNP/Transparent mode,
Dip switch 4 must be in the OFF position
nn
In Force-10 mode, the McBasic 10/100 permits the transmission
of valid 10 Mbps traffic only. In this mode, the module acts as a
10BASE-T/10BASE-FL media converter, rejecting 100 Mbps
signals.
To enable Force-10 mode, set Dip switch 5 to the ON position
(Dip switch 4 must be in the OFF position). To disable Force-10
mode, move Dip switch 5 to OFF (factory default).

nn
In Force-100 mode, the McBasic 10/100 configures specifically as
a 100BASE-TX/100BASE-SX or FX media converter. Note that
Force-100 implies the rejection of 10 Mbps signals.
To enable Force-100 mode, set Dip switch 6 to the ON position
(Dip switch 4 must be in the OFF position). To disable Force-100
mode, move Dip switch 6 to OFF (factory default).
Note: Force mode should be used when any of the devices connected to the
media converters DO NOT support Auto-Negotiation. Do NOT enable both
Dip switches 5 and 6. Only one switch should be enabled at any given time.
IMPORTANT: It necessary to power down and then power up again
before the above Dip switch changes will take effect!
Connecting Half Duplex or Full Duplex and 10 or 100 Mbps Devices
When connecting two McBasic 10/100 media converters between two
stations (devices such as switches, hubs and repeaters), unless both end
stations are set to the same speed/duplex, one end station MUST be settable
through PNP/Transparent (Auto-Negotiation) mode (i.e., can handle both
10/100 and/or HDX/FDX). If the end stations Duplex or speed cannot be set
through Auto-Negotiation mode, then both end stations must be set for the
same configurations manually. The following diagram shows a typical
application with several configuration scenarios:
Note:
McBasic 10/100 cannot be manually set for Half or Full Duplex.
Twisted Pair Crossover/Pass-Through Switch
The twisted pair port on McBasic 10/100 has one RJ-45 connector for a
single shielded or unshielded twisted pair link segment, and features a pushbutton, 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.
LED Operation
McBasic 10/100 features several diagnostic LEDs per port. The LED
functions for McBasic 10/100 are:
Twisted Pair Port
LNK Glows green when a twisted pair link is established
NOTE: Fiber optic cable must also be connected before the
twisted pair ports Link LED will light.
ACT Blinks yellow when data is detected on the port
100 Glows green when 100 Mbps data is detected
LFD Glows green when Link Fault Detection is available
NOTE: This feature is only available when PNP/Transparent
(Auto-Negotiation) mode is enabled. For more on this feature,
refer to the Troubleshooting section later in this document.
AN Glows green when PNP/Transparent (Auto-Negotiation) mode
is enabled
PWR Glows green when unit has power
Fiber Port
100 Glows yellow when 100 Mbps data is detected
LNK Glows green when a fiber link is established
NOTE: The twisted pair cable must also be connected before
the fiber optic ports Link LED will light.
ACT Blinks green when data is detected on the port
NOTE: The fourth LED in this stack in reserved for future use.
Troubleshooting
Ideally, McBasic 10/100 should be implemented into a media conversion
installation where both sides are Auto-Negotiating. In this scenario where
PNP/Transparent (Auto-Negotiation) mode is enabled on McBasic 10/100,
the feature Link Fault Detection (LFD) is available. If a fault occurs, Link
Fault Detection carries the link fault through the entire media conversion,
dropping all Link LEDs.
For installations where Auto-Negotiation is not possible from one end of
the media conversion to the other, McBasic 10/100 can be forced into
either 10 Mbps or 100 Mbps mode. Link Fault Detection is not available
and McBasic 10/100 acts as a normal media converter.
