Problem with usb connection of DDS AD9914

Category: Hardware
Product Number: DDS AD9914

Recently, I have encountered a problem with my newly bought DDS AD 9914. The USB connection was working before but next day I connected it again to the PC it started showing the following error. I have tried restarting the computer and USB driver reinstallation but nothing worked. The USB connection corresponding to the different AD devices are working. So it seems like it is a hardware problem. Is there any way to fix it?

  • Hi  ,

    Just checking how the LED status looks like? How it blinks or what color it gives? 

    Have you tried plugging it in a new computer or using a new connector? Issues might be there. 

    This can also be an alternative solution. An unsuccessful connection is indicated by a flashing red USB icon located at the bottom right corner of the window of the evaluation software. Most installation errors can be resolved by checking jumper settings, making sure that the evaluation board is powered up correctly, and inspecting the USB port and cable connections. When all power, USB port/cable connections, and jumper settings are correct, an error may still appear if the clock input is not configured properly. Check to make sure that the clock input source is connected and configured properly. Another reason an error may appear is due to the presence of a conflicting device driver.

  • Hi,

    Thanks for the reply. 

    The LED is green as it is supposed to be. The computer is detecting the USB connection but cannot connect with the device. It shows the same error shown in my previous post.

    There is no problem with the software on the computer since it was working before. I think the last time when I used it, I just turned off the device, and it damaged something in the device hardware. I was wondering if it is possible to replace a component and make it work.

    I have connected it with the other computers, but the same problem persists.  

    Thanks

  • Hi  ,

    Can you send me a screenshot of your device manager interface on how it detects the device? I'm thinking this can be solved by reprogramming the EEPROM.

    As for replacing a component, yes that is doable but doing so might affect other components and more problems might arise. 

    All the best,

  • Hi,

    Please find the attached screenshot of the device manager.

    Thanks

  • Hi  ,

    Let's try reprogramming your EEPROM.

    You can use this pdf for a detailed step by step guide. Just let me know if it works or if you encounter any issues while doing it.
