Hi,
I have connected the EVM and after a bit of trouble I was able to get it up and running, Turns out I had to download the latest drivers from National Instruments. Now I can at least connect the software GUI to it without it asking me to "retry" the USB connection. Had nothing to do with the USB driver.
After spending a whole day I cannot simply connect a signal generator to line 2 L and get an output from either headset left channel (in SE) or line output in left channel. I have checked jumpers and settings according to the user manual. I do recall having some output for a moment but it quickly disappeared. Looked like hardware was not getting a stiff bias and the center reference voltage was floating around or drifting. The signal then begins to disapear with clipping on the positive side of the sine wave. I thought it may be the ADC reference voltage was not set. Anyway, if anyone has had this problem, please let me know. It may be just operator error on my part. Staring at the screen for hours can make you miss something staring you in the face! I've pressed every button imaginable on the GUI but other than the offset drifting output I managed to get, nothing. Maybe I just have a busted board? Oh I noticed the signal would appear if I raised the input level from my signal generator. Perhaps causing the inputs to self bias momentarily?
Thanks,
Jerry
