6 ADS131B04-Q1EVM Operation

The following instructions are a step-by-step guide to connecting the ADS131B04-Q1EVM to the computer and evaluating the performance of the ADS131B04-Q1:

  1. Connect the ADS131B04-Q1EVM to the PHI. Install the two screws as indicated in Figure 10.
  2. Use the provided USB cable to connect the PHI to the computer.
    • LED D5 on the PHI lights up, indicating that the PHI is powered up
    • LEDs D1 and D2 on the PHI start blinking to indicate that the PHI is booted up and communicating with the PC. Figure 10 shows the resulting LED indicators
