About McBasic Gigabit
McBasic Gigabit™ is a low-cost, preconfig-
ured, IEEE 802.3 single-conversion media
converter that converts between 1000Base-TX
twisted pair and 1000Base-SX multi-mode or
1000Base-LX single-mode fiber. It is available
with one RJ-45 connector for the twisted pair
port and an SC connector for the fiber port.
McBasic Gigabit is a 1U high, stand-alone
unit that includes diagnostic LEDs for each port and a universal (100/240
VAC) power supply.

Installing McBasic Gigabit
McBasic Gigabit comes ready to install. The only adjustments that may
need to be made come after installation.
To install McBasic Gigabit, first make sure that the unit is placed on a
suitable flat surface. Attach the cables between the McBasic Gigabit and
each device that will be interconnected, then plug the unit into a reliable,
filtered power source.
Configuring McBasic Gigabit
Once installed, McBasic Gigabit can be configured for the following fea-
tures by the end user:
• Duplex Mode (Default = OFF, Full-Duplex)
• Master/Slave Mode (Default = ON, Master Mode)
• FiberAlert (Default = OFF)

McBasic Gigabit 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 defini-
tions of the function of each switch. More

The Duplex mode settings of the McBasic Gigabit converter are used with
Auto-Negotiation. The default Duplex mode for McBasic Gigabit is Full-
Duplex. In this mode, Full-Duplex is advertised during Auto-Negotiation.
To make the unit operate in Half-Duplex, simply move DIP switch 1 from
the OFF to the ON position. This will allow only Half-Duplex to be adver-
tised during Auto-Negotiation. The Auto-Negotiation takes place on the
twisted-pair interface only. When the twisted-pair interface is resolved, the
configuration will be encoded into the fiber side. No Auto-Negotiation takes
place on the fiber side. As a result, it is usually best to disable Auto-
Negotiation on the remote fiber end. Since most gigabit networks run at
Full-Duplex, it is recommended to set the remote fiber end to Full-Duplex.

This feature determines which clock will be used between the
McBasic Gigabit and the device it is connected to (a switch, NIC, or another
McBasic Gigabit, etc.). Master mode is the default setting, where McBasic
Gigabit's clock is used. To change this to the Slave setting, move DIP switch
2 to the OFF position. McBasic Gigabit will then receive and use the clock
of the other connected device. The Master/Slave mode is only valid for the
twisted pair link.

If your unit is running and you change either the Duplex Setting or
Master/Slave mode, you will need to reset your unit before these changes
take effect. The Reset button located on the front faceplate can accomplish
this. To reset the unit, take a slender, non-conductive object, about the
width of a paper clip, insert it into the hole in the chassis, and press the
Reset button inside. Please observe proper ESD procedures when resetting
your chassis. Note that power cycling the unit (i.e. removing the power
cord and then reconnecting it) will also reset McBasic Gigabit.
