Get to Know the TWR-IND-IO

TWR-IND-IOFreescale Tower System

The TWR-IND-IO 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 prototyping with your Tower System today.

TWR-IND-IO Features

• USB to Serial Ready Play solution, providing serial connectivity via USB
• RS-232 transceiver with available flow control signaling
• RS-485 transceiver with optional isolation and PROFIBUS capability
• Dual CAN transceivers
• Analog signals accessible via screw terminals: 3x ADC, 1x DAC, VDDA, VSSA
• Digital signals accessible via LEDs and thru-hole points: 6x PWM, 3x timer
• Signal jumpers to allow isolation, probing and remapping of interfaces
• Compatible with the TWR-SER to provide access to additional industrial I/O interfaces

Step-by-Step Installation Instructions

1. 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.

2. 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.

3. 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.

4. 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.
