DAC3283EVM: DAC3283EVM shows up as DAC5688 in Windows 7 x64

Part Number: DAC3283EVM
Other Parts Discussed in Thread: DAC5688, , DAC3283, DAC3282EVM-SW, DAC5688EVM, DAC3282EVM, DAC3282

I run setup.exe in the folder DAC3283_Installer_v2p3 to install DAC3283_GUI_v2p3 for DAC3283EVM Rev D. The operating system is Windows 7 x64. When plugging in the USB cable, the device driver failed to install. It is interesting that the Device Manager shows the device is DAC5688 with the following hardware IDs USB\VID_0001&PID_5688&REV_0600 USB\VID_0001&PID_5688. The link to DAC3282EVM-SW is not available. Please advise. Thank you.

  • Hi Kenneth,

    We are taking a look into this issue. Just to make sure, you have the DAC3283EVM, and, when you run the DAC3283 GUI, the GUI does not recognize that the DAC3283EVM is connected? Did you install/launch the GUI as Administrator?


  • Hi Dan,
    Yes, I do have a DAC3283EVM Rev D. When I run the GUI as an Admin, I get a warning on device communication failure, which is interestingly recognized by Windows as DAC5688, and therefore is not recognized by the GUI for DAC3283EVM. To my surprise, it is recognized by the GUI for DAC5688EVM. Is it possible that the FTDI configuration for the FT245RL has been tampered with? I wonder if I can get the correct FTDI configuration to restore it for this DAC3283EVM using FT_PROG.
    Thank you.
  • Hi Kenneth,

    I have the DAC3282EVM here in the lab, and I have saved its FTDI settings (using FT_Prog) in a template file. The DAC3282 and DAC3283 are almost identical except for they have different maximum sampling speeds (625MSPS and 800 MSPS). I have verified that the GUI "DAC3283_GUI_v2p3" detects this device.

    <?xml version="1.0" encoding="utf-16"?>
        <bcdUSB>USB 2.0</bcdUSB>
        <Product_Description>FT245R USB FIFO</Product_Description>
        <SerialNumber />

    Before loading the above template, PLEASE SAVE your current FTDI settings using section 4.3 of the FT_PROG User's Guide.

    Please follow the steps in section 6.3 and 6.4 of the FT_PROG User's Guide in order to load the attached DAC3282EVM FTDI template.

    After you have loaded the template, please verify that the DAC3283 GUI detects your EVM. If you have any issues, please let me know.
