How to attach the TWR-LCD module
Locate the “functional”
Elevator in the
assembled Tower Kit.
Press the expansion
connectors on the
back of the TWR-LCD module
onto the the matching Side
Expansion Port connectors
found on the outer side of the
“functional” Elevator.
Proceed to the “How
to build your Tower”
section to complete the
assembly of your Freescale
Tower System.
Note: Once the TWR-LCD module is
affixed to the “functional” Elevator, it will
be difficult to remove. Removal of the
TWR-LCD module is not recommended.

Freescale Tower System
The TWR-LCD module is part of the Freescale Tower System, a modular
development platform that enables rapid prototyping and tool re-use through
reconfigurable hardware. Take your design to the next level and begin
constructing your Tower System today.
How to build your Tower
STEP

Locate the Elevator modules,
identifiable by the four card
edge connectors on each.
Identify each Elevator module
as either “functional” or
“dummy” (written on the
outward facing side of
the board).
Locate the other modules you
will use in your Tower System.
Identify the “primary” and
“secondary” card edges for
each module (written along
the edge).
Plug the “primary” card edge
of each module into the
“functional” Elevator.
Place the remaining “dummy”
or “functional” Elevator module
onto the “secondary”
card edges.
