NI PCI 6733 anlog out put card

[Riaz]

Helo how r u

 i have 6733 card and it is not giving any analog output. card serial no is 11A2E80 and i have not used it much. i have just checked first months earlier and now it is not giving any analog out put on any output port. cam u help me troubleshooting this device and if there is any problem with the hardware can you tell me about its warranty validity.

Thanks

On MAX, is the device showing up??

If it shows up,  Does it pass 'self test' on MAX??

do try this and if it still fails, contact your local NI support team for assistance

It is passing the self test. But not calibrating when done from MAX. Showing an error of some external interference or noise. and there is no analog out on any AO line but other digital and counter functions are working properly. can yo guide me how to troubleshoot it and what culd be the possible cause of this problem.

Hi Riaz,

I'm not clear on what you mean by "But not calibrating when done from MAX. Showing an error of some external interference or noise." Is there a specific error that you are receiving?  How are you checking the analog output? 

This type of behavior (not seeing an output) can occur for many reasons.  It is possible that a software error is occurring, wiring is loose or incorrect at the output, the driver could have become corrupt, or the board may be damaged and needs to be sent in for repair.  Due to the nature of the issue, this problem would be best solved if you visit ni.com/support to request phone support with an NI Engineer.  This way you can quickly rule out possible causes and arrange for the board to be repaired if necessary.  We would also be able to answer any questions about warranty at that time.

In the meantime, verify your connections and test the board in another PC if possible.

Hi,

I have the same problem. My PIC 6733 failed to produce any output voltage. I did self-test using MAX and it passed. But when run the calibration, it failed due timeout error.

I did run test panel for analog output, direct dc, no output voltage at all.

But for DIO, everything was running ok.

Any suggestion.

Howdy Jancanes!

What method are you using to verify the there is no analog output voltage? Hand-held multimeter, oscilliscope, etc...?

What voltage do you see on the output (0V or some other voltage regardless of the setting) and what are you measuring it in reference to?

Do all the channels appear to have the exact same behavior?

I'm using  Hand-held multimeter. The output is 0.26V on all channels.

The way I measure it is by using MAX(Direct DC-then Update), at the same time applying ground (from multimeter)to AO Ground, then measure it to any AO channel. No changes at all.

Is it the correct way to measure it.

By the way I measure 5V reference, it is producing 5V.

You are testing it correctly and unfortunately it sounds like your card is broken.  Please create a service request here to return the card for repair.

Good Day Sir,

Our system is using  PCI 6733 analog output card.

This CCA is been used in the CosMos system.

We received a Spare  Analog output.

We don't have any test set to verified the spare.

What we have to do is just plug our analog output CCA into the system to verified the serviceability.

Before we put in the spare CCA, We verified our system and the system working fine.

We removed the original CCA from the CosMos Computer and placed the spare CCA into the system.

The CosMos system unable to engaged.

We removed the spare CCA and placed the original CCA back to the Cosmos Computer.

Our system failed to engage.

We run the software utility to test the CCA. 

Voltage check was carried out at the the output pin and we found there is no changes of voltage at the output pin.

Both of the CCA produce the same result.

Comparision Voltage Chech was carried out between the Two PCI slot.

We found that there is defference in Voltage at pin 6 and 7 of  the suspected defective PCI slot.

     Pin           Suspected defective Slot         Good Slot

                      Slot B/B      Slot A/B             Slot B/A  Slot A/A

      6                 5.08           5.08                    5.08      3.876

       7                3.875           5.08                   5.08       5.08

My Question is

What is the correct voltage for pin 6 and 7 for the PCI 6733 ?

May this two voltage make our TWO CCA become defective. ?

What is the right step before we placed a new CCA in our system ?

Please advise us.

Thanks in advance

Hi Aro,

I don't understand what you are refering to by "CCA" and the "CosMos system".  Also, would you please clarify what you mean with your naming convention for slots (B/B, A/B, B/A, A/A). 

The two pins you are asking about on the PCI-6733 represent the following signals:

Pin 6 -> PFI 5/AO SAMP CLK

Pin 7 -> Digital Ground

When you are measuring the value on those pins what are you measuring it in reference to?  Also, what software are you running that would be affecting the output of the card?

Regards,
