How to attach the TWR-LCD module
STEP
Locate the “functional”
1
Elevator in the
assembled Tower Kit.
STEP
Press the expansion
2
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.
STEP
Proceed to the “How
3
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.
TOWER SYSTEM
How to build your Tower
STEP
Locate the Elevator modules,
1
identifiable by the four card
edge connectors on each.
STEP
Identify each Elevator module
2
as either “functional” or
“dummy” (written on the
outward facing side of
the board).
STEP
Locate the other modules you
3
will use in your Tower System.
TWR-LCD
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.
STEP
Identify the “primary” and
4
“secondary” card edges for
each module (written along
the edge).
STEP
Plug the “primary” card edge
5
of each module into the
“functional” Elevator.
STEP
Place the remaining “dummy”
6
or “functional” Elevator module
onto the “secondary”
card edges.
