9.2 Troubleshooting
If the ADS1247EVM plug-in cannot find the ADS1247EVM-PDK, press the USB RESET button on the
MMB3 (refer to Figure 6) and try again.
If ADCPro stops responding while the ADS1247EVM-PDK is connected, try unplugging the USB cable
from the PDK. Unload and reload the plug-in before reapplying power to the PDK.
