TWR-S08GW64-KIT
Freescale Tower System
The TWR-S08GW64 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. The
TWR-S08GW64-KIT comes with two elevator modules (TWR-ELEV)
and a prototype module (TWR-PROTO).

Basic steps for the Tower System
hardware installation
FortheLCDLAB,thefollowingcardsof
the Tower System are required:
1. Tower System Primary Elevator
2. Tower System Secondary Elevator
3. TowerSystemSerialModule
4. TowerSystemGW64Controller
Module
HowtoConnect:
1. There are four slots each on Primary
and Secondary Elevator card. All four
slots are identical to each other.
2. TaketheGW64Controllercardand
insertthePRIMARYconnectorsidein
thePrimaryElevator,matchingthe“B”
marking of the Elevator card and the
controller card in any of the four slots.
3. TaketheSerialModuleandinsert
thePRIMARYconnectorsideinthe
PrimaryElevator,matchingthe“B”
marking of the Elevator card and
theSerialModuleinanyofthethree
remaining slots.
4. Take the Secondary Elevator card and
fit it on the other side of the GW64
ControllerandtheSerialModulecard,
againmatchingthe“B”markingso
that it forms a Tower-like structure.
The Tower System is now in place.
