PCI-6025E error Diagnostic Utility hangs.

[laserscan_guy]

Hi,

I'm a forum newbie but have been using the 6025e's for nearly 20 years.  

I'm having the same problem as-   https://forums.ni.com/t5/Multifunction-DAQ/PCI-6052E-error-200329-Diagnostic-Utility-hangs/m-p/16081...    

 -but with the 6025e

Where is the "the clock trace leading to the ADC"?

Is there a version of the diagnostics that allows separate testing of the individual modules on these cards?  (I have 2.1.0)

Any help gratefully received as i have 5 of these that are faulty.  (And about 50 in the field.)  They all read analogue voltages correctly but are not triggering on measured events.

Cheers.

Hey laserscan_guy,

The clock trace to the ADC is an internal trace on the device, and 2.1 is the latest diagnostic utility. To confirm, these devices worked in the past and recently became faulty?

Hi Mike,

Thanks for the quick reply.  Yes, were working.  Where specifically is the "trace"?  Why would a trace fail?

Mike??

Is it likely to be blown 82c55's??

I apologize for the delay, and yes to appears the hardware may be faulty itself, as was the case for the user in the forum post you referenced at the top of this chain.The clock trace is a copper line on the circuit board of the device. They are named traces because the machine that manufactures the board "traces" the design when cutting out the wires. The primary cause for blowing a trace is exposure to a voltage/current/power level over the rating of the device.

Thanks for the partial answer.

In my experience, boards are ether printed or etched. Particularly multi-layer ones.  Normally the "wire" is called a track and they very rarely "blow".  Usually ICs are damaged well before the tracks are.  

Do you have any better advice as to where I need to look?  You (by that I mean NI) must have received many 6025e  cards back for repair with identical symptoms. What was the faulty component? Is it likely to be the 82c55 chip?   Do you have a better diagram than the block diagram in the user manual?

Hi laserscan_guy,

Our RMA team here at NI has more powerful tools to successfully debug the issue with your cards. If you would be interested in having your devices inspected and tested to see where the issue within your device lies (including the 82c55), please call your local support number and they will be more than happy to handle the request.
