6036 E-Series AI Internal Sample Clock

[The New-Guy]

I have a 6036 E-Series board and am implementing the DAQmx Analog Input.  I want to use the Internal Sample Clock

instead of software timing.  I've reviewed and tried to run the examples provided, but only the software timed routines

function.  All of the Internal Clock routines sit and wait for the timeout to occur.  Any help would be appreciated.

What code do you have?
Could you give a screenshot (please no express VIs)
I have no issues with the 6036 (that's the PCMCIA right?)

Hello TonP,

The code is directly from Labview 7Express "NI Example Finder", search: DAQmx Analog Input Voltage,

->Continuous Acq&Chart Samples-Int Clock.vi (filtered for 6036 E -series)-see attached cut 'n pastes.

I do NOT want to use an External Clock or Software timing.  This AI routine is part of a larger picture of AI, AO, DIO

and Counters to be implemented in a large VI and eventually synch'd together (for later).  I've tried all related Int Clock

examples, with same timeout result.  It's as-if the Int Clock is not being addressed.  Is this the same Int Clock that

AI Traditional uses?  Is there only one clock?  Do AI, AO, DIO use/rely on same clock?  Do I need to address a specific

clock or is it automatically implied?  Oh yes, this is PCMCIA.

Hi,

What version of the NI-DAQmx driver are you using?  If you are using NI-DAQmx 7.5, 8.0, or 8.1 please install and run the DAQ Diagnostic Utility found here.  Are you able to run a Test Panel in Measurement and Automation Explorer for your 6036E?  On the Analog Input test panel you can change the mode to "finite" or "continuous" to use the onboard clock for sampling.  Does this 6036E behave the same way in another similarly configured laptop?

Hello TheWoost,

I've downloaded and ran the utility (see results attached).  By the way, I have LabView 7.0, Labview engine 7.0,

MAX 4.03.3003, DAQmx 8.1.0f1.  As you can see from the attached results, many things failed.  The utility "read-me"

says minimum Labview engine 7.1, though mine is 7.0 (problem?).   I also tried the Analog Input panel set on finite

and also continuous.  It would not give an output (blank).  It would work "on-demand".  I have not tried the card

in another laptop, since this is the best one we have.  Maybe I should uninstall the LabView 7.0 engine and install

something more current?  Other drivers?

Ooops!  This has the diganostics results.

[TheWoost]

The LabVIEW Runtime Engine 7.1 should have been installed with the DAQmx driver, and the utility would not have run had version 7.1 not been on your system.  The results you see in the test panel as well as the DAQ Diagnostic Utility point heavily to this being a hardware issue, but it would be a good idea to rule out a problem in the software.  NI-DAQmx 8.1 is the most recent version of this driver that can install support for LabVIEW 7.0.  Please uninstall NI-DAQmx from your system, and download and reinstall NI-DAQmx 8.1. After you have done this please try out the previous troubleshooting steps.  If you still see the same behavior your device may need to be repaired.  Let us know what you find out.

Hello,

you could try raising the sample rate!
