2 ADS131A04EVM Quick Start Guide

The following instructions are a step-by-step guide to connecting the ADS131A04EVM to the computer and evaluating the performance of the ADS131A04:

  1. Review the default jumper settings in Section 6 and GUI software installation in Section 6.2.
  2. Connect the ADS131A04EVM to the PHI. Install the two screws as indicated in Figure 2-1.
  3. Use the provided USB cable to connect the PHI to the computer.
    1. LED D5 on the PHI lights up, indicating that the PHI is powered up
    2. LEDs D1 and D2 on the PHI start blinking to indicate that the PHI is booted up and communicating with the PC. Figure 2-1 shows the resulting LED indicators.
