2 Getting Started With the ADS1x48EVM

The following list of steps provides an overview to quickly get the ADS1x48EVM setup and operational. The subsequent sections in this document expand on each step in order to explain in detail the available features on the ADS1x48EVM and the corresponding GUI. Links are provided to navigate from this quick-start guide to the appropriate section at each step, where applicable.

  1. Remove the ADS1x48EVM, PAMBoard, and USB cable from the ADS1x48EVM box.
  2. If necessary, connect the ADS1x48EVM to the PAMBoard as shown in the left image in Figure 2-1.
  3. Set the ADS1x48EVM jumpers to the desired location:
    1. Power
    2. Clock
    3. RTD connections (if applicable)
  4. Connect the micro-USB-to-USB cable from the PAMBoard directly to a USB port on the computer. Do not connect the cable through a USB hub.
  5. Open up the web-based GUI available on the EVM landing page (ADS1148EVM-PDK or ADS1248EVM-PDK).
    1. First-time users may be prompted to download and install the browser extension for Firefox™ or Chrome™ and the TI Cloud Agent Application. Installing the TI Cloud Agent is a one-time download and installation.
  6. Refresh the GUI such that a green signal displays and the Hardware Connected indicator shows in the bottom status ribbon (see Figure 4-2).
  7. Select the desired ADC reference voltage.
  8. Connect your sensors or signals to the input terminal blocks (J5 and J6).
  9. Capture and analyze data using the GUI.
