About McBasic 10/100
McBasic 10/100™ is a low-cost, standalone,
IEEE 802.3 single-conversion media
converter which converts between:
• 10Base-T twisted pair and
10Base-FL single- or multi-mode fiber
• 100Base-TX twisted pair and
100Base-SX multi-mode fiber
• 100Base-TX twisted pair and
100Base-FX single-mode fiber
McBasic 10/100 is a 1U high, standalone unit that includes diagnostic
LEDs for each port and an internal, universal (100/240 VAC) power supply.

Installing McBasic 10/100
McBasic 10/100 comes ready to install. The only adjustments that may
need to be made after installation are:
• Configuring the unit for its mode of operation and other features.
• 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, leaving 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.

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. After
configuring the switch, power down the unit and
then power up again for the DIP switch changes to
take effect. The following table provides simplified

McBasic 10/100 features three possible "modes" of operation:
Auto-Negotiation/PNP mode, Force-10 mode and Force-100 mode.
McBasic 10/100 should be configured for one of these modes (factory default is
AN/PNP mode). Refer to pages 3-5 for information on Link Fault Detection.
McBasic 10/100 cannot be manually set for Half- or Full-Duplex. Duplex
is determined by the devices to which McBasic 10/100 is connected.
•
Auto-Negotiation mode, also known as PNP, 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)
depending on the capabilities of the end stations.
To enable Auto-Negotiation/PNP mode, set switch S6 to the ON
position, with switches S7 and S8 in the OFF position.
• In Force-10 mode, McBasic 10/100 permits the transmission of valid
10 Mbps traffic only. In this mode, the unit acts as a 10Base-T/
10Base-FL media converter; 100 Mbps signals
To enable Force-10 mode, set switch S7 and S8 to the ON position,
with switch S6 in the OFF position.

Auto-Negotiation Mode (Plug-N-Play)
(Valid only when Force mode is disabled)
Force Mode — Forces McBasic 10/100 to operate
at 10 or 100 Mbps as determined by S8
When ON, McBasic 10/100 operates at 10 Mbps
When OFF, McBasic 10/100 operates at 100 Mbps
S8 is only valid in Force Mode, i.e. when S7 is ON
