3.1 Hardware

To experiment with the TIDM-1011, the following hardware components are required:

  • TIDM-1011 BoosterPack (also known as the BOOSTXL-POSMGR)
  • External, 5-V, DC power supply (see Table 1-1)
  • A Supported LaunchPad featuring a C28x device with the Configurable Logic Block (CLB). Refer to Table 2-1 for a list.
  • USB-B to A cable
  • T-Format Absolute Encoder from Tamagawa (for example, TS5700N8501)
  • 4-pin cable from Tamagawa – length as required by the application (maximum 100 m)
  • Custom adapter to connect Tamagawa, 4-position, female-terminated cable to wire leads adapter
  • PC with Code Composer Studio (CCS) v12.0.0, or greater, installed
Note: Not all Tamagawa absolute encoders use T-Format for communication. To use the provided software as-is, the format must be T-Format.
