USB-6289: +5V pinout doesn't give a signal

Hello,

 

My USB-6289 has developed a sudden problem with its +5V DC out. I was checking the signal quality of the +5V signal on my oscilloscope, disconnected, connected a counter (PFI12, ctr0) to the scope, ran a few pulse trains (I am using Igor Pro to control the DAQ), stopped the counter, and reconnected the +5V signal to find that is dead. 

 

I am not sure if I have inadverdantly overloaded the output somehow. The USB-6289 does self-test OK, and the digital and analog output still work fine. It is just the +5V that is not outputting -- is there a software option that may have accidentaly turned it off? 

 

Regards, 

Arun

Here is the DAQ Diagnostic Test 2.0 result. It shows that one of the DAC's (A0) is malfunctioning, but says that the digital i/o is ok -- what does this mean? Can there still be hardware damage?

 


Selected Device: Dev2


Device Type: USB-6289

The +5V pin should always be high. Are you sure it's not shorted to GND (or some other low signal), maybe in your DUT board?

If not, I fear the output stage is damaged...

Hey it seems like you card could be broken.
