  • DS4404 EV kit hardware
  • Windows XP or Windows 7 PC
  • USB port
  • Micro-USB cable Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly from the install or EV kit software. Text in bold and under- lined refers to items from the Windows operating system. Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation: 1) Place the EV kit hardware on a nonconductive surface to ensure that nothing on the PCB gets shorted together. 2) Prior to starting the GUI, connect the EV kit hardware to a PC using the mini-USB cable, or equivalent. The power LED (D20) should be green and the com LED (D21) should be red and slowly flash orange. 3) Windows should automatically begin installing the necessary device driver. The USB interface of the EV kit hardware is configured as an HID device and there- fore does not require a unique/custom device driver. Once the driver installation is complete, a Windows message appears near the System Icon menu, indicating that the hardware is ready to use. Do not attempt to run the GUI prior to this message. If you do, then you must close the application and restart it once the driver installation is complete. On some versions of Windows, administrator privileges may be required to install the USB device. 4) Once the device driver installation is complete, visit www.maximintegrated.com/evkitsoftware to download the latest version of the EV kit software, DS4424EVKitSoftwareInstall.ZIP. Save the EV kit software to a temporary folder. 5) Open the .ZIP file and double-click the .EXE file to run the installer. A message box stating The publisher could not be verified. Are you sure you want to run this software? may appear. If so, click Yes. 6) The installer GUI appears. Click Next and then Install. Once complete, click Close. 7) Go to Start | All Programs . Look for the DS4424EVKitSoftware folder and click on the DS4424EVKitSoftware.EXE inside the folder. 8) When the GUI appears, the text in the bottom right-hand corner should display EV Kit Hardware Connected. The com LED (D21) on the EV kit board should turn green. Note: The .EXE file is downloaded as a .ZIP file. FILE DESCRIPTION DS4424EVKitSoftwareInstall.EXE Application program DS4404 EV Kit Files

Red USB Power Fault: A fault occurred due to overvoltage limit, current limit, or thermal limit. Green USB Power: USB power supply is on. when an I2C command is received. Green Initialized: Hardware has been initialized by software. not sitting on a conductive surface. Windows message that states the hardware is ready to use. Are any of the LEDs illuminated? If not, then the PCB may not be getting power from the USB. Try a different USB cable or a different USB port. Table 1. Slave Addresses Table 2. Description of LEDs Table 3. Troubleshooting
