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
- 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.
