About McBasic
McBasics™
are low-cost, preconfigured,
IEEE 802.3 single-conversion MediaConverters
that convert between 10Base-T twisted pair
and either 10Base-2 thin coax or 10Base-FL
multi-mode or single-mode fiber. It is avail-
able with one RJ-45 connector for the twisted
pair port and one pair of ST or SC connectors
(or a VF connector) for the fiber port or one
BNC connector for the coax port.
McBasic TP/FO™
and
McBasic TP/BNC™
are 1U high, stand-alone
units that includes diagnostic LEDs for each port and a universal
(100/240 VAC) power supply.

Installing McBasic
McBasic comes ready to install. The only adjustments that may need
to be made come after installation.
To install McBasic, first make sure that the unit is placed on a suitable
flat surface. Attach the cables between the McBasic and each device that
will be interconnected, then plug the unit into a reliable, filtered power
source.

• Select a crossover or pass-through connection for the twisted pair
port (default = OUT/crossover)
• Enable
LinkLoss (default = DOWN/disabled)
• Enable FiberAlert (default = DOWN/disabled)
McBasic TP/BNC can be configured for the following:
• Select a crossover or pass-through connection for the twisted pair
port (default = OUT/crossover)
• Disable BNC port termination (default = ON position/enabled)
Twisted Pair Crossover/Pass-Through Switch
The twisted pair port on McBasic TP/FO and McBasic 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 connec-
tion.
Select a pass-through connection by pressing the push-button IN. A
crossover connection is selected when the push-button is OUT. If uncer-
tain whether a crossover or pass-through connection is needed, set the
push-button to the position that makes the TP LNK (link) LED glow.
BNC Port Termination
McBasic TP/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 McBasic TP/BNC is attached to a mid-point of
a thin Ethernet segment, attach a ‘T’ connector to
the BNC port. Termination must be OFF (dis-
abled). Termination is disabled when the switch is
in the left position.
If a thin Ethernet segment is to be terminated at
the McBasic TP/BNC, attach the cable directly to
the BNC connector and set the termination switch to ON (enabled – facto-
ry default) by moving the switch to the right position.
Troubleshooting with LinkLoss and FiberAlert
LinkLoss and FiberAlert are advanced troubleshooting features from IMC
Networks that can help you use your McBasic TP/FO to locate “silent fail-
ures” 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
install the enclosed module/unit.
