Step-by-Step Installation Instructions
Configure
Jumpers
ConfiguretheTWR-IND-IOjumpersto
align with the intended Tower System
controllermodule.Beawarethatnot
all controller modules will provide
access to all features available on the
TWR-IND-IO. Refer to the Jumper Table
in this document for reference and
the user manual for additional details
regarding the flexibility of this module.
Ensure
Compatibility
Eachinterfacefeaturedonthe
TWR-IND-IO is capable of being
isolated from the Tower System.
To maintain the best compatibility
with additional Tower peripheral
modules it is recommended that any
unused interfaces be isolated.
Assemble Your
Tower System
AssembleyourTowerSystem,
including a Tower System controller
module, the TWR-IND-IO peripheral
module,andtheTWR-ELEVelevator
modules. Refer to the assembly instructions
providedwiththeTWR-ELEVmodulesforcorrect
orientationandassemblyofboards.NOTE:The
TWR-IND-IO module is intended to be compatible
withtheTWR-SERserialmodule,thusexpanding
the number of available interfaces.
Refer to Additional
Materials
Many existing MQX
™
exampleprojectscanbe
adapted to utilize the respective I/O interfaces on
the TWR-IND-IO by modifying the “user_config.h”
fileandrecompilingtheMQXBSP.Refertothe
TWR-IND-IO user manual and the latest MQX
release notes for details. Refer to the TWR-IND-
IO page on freescale.com/Tower for additional
informationandexampleapplicationprojectsfor
select Tower System controller modules.
