How to acquire data from the memory of multimeter

I am a beginner of Labview. I don't know how to acquire data from the memory of multimeter.
I read some examples about DAQ, but it seems not similar to my case. I can't use DAQ in my computer, as I don't have DAQ board.
Could anybody give me some guide? Similar examples would be great.
Solved!

Confirm that you have the VISA Run Time Engine on the target machine. If you do not have it installed, you can install the VISA Run Time Engine from ni.com.

How do i pin from FB using firefox ???!!!??

How do I pinterest from FB using firefox ?
I dont want to install chrome- I dont want to waste the space. I cant believe firefox doesnt have a way to do it- they must ??!!

Pinterest offers two solutions for Firefox users. One is an add-on button, and the other is a "bookmarket."
What's the difference?
* Add-on (extension): This creates a graphical "P" button that you can place on your main Navigation toolbar. The add-on is running all the time, and may have more advanced features.
* Bookmarklet: This creates a text button on your Bookmarks Toolbar. It doesn't do anything until you click it, at which point is adds a script into the page you're viewing.
''Note:'' if you do not generally display your Bookmarks Toolbar, then the bookmarklet might not be convenient for you. You can show that bar using either:
* View menu > Toolbars
* right-click a blank area of the tab bar (or the "+" button)
What do you think?
To grab either of the Pinterest buttons, go to this page: http://about.pinterest.com/goodies/#browser
There is a small link to switch between the add-on and the bookmarklet.
Any luck?

Force exponential window in sound&vibration toolkit

hello,
I work on shock acquisition and analysis. I would like to use a window "force exponential" before computing fft. But I don't find the vi to do it directly in sound&vibration toolkit and VI express toolkit.
So I try to do it by using the VI in signal processing toolkit (see the link picture please) but I lost the time data information (the VI uses array data and not dynamic data with time). how to recover the time data?

Bonjour,
Je ne suis pas sur d'avoir bien compris, vous désirez avoir le temps écoulé ? le temps où la mesure a été faite ? Pouvez vous me donnez plus de précisions svp. Ci-joins un vi en 8.5 qui pourra peut-être vous inspirer.

The difference of sinad.vi between Sound & Vibration Toolkit and Singal Processing Toolkit

Hi, I'm confused with the the difference of sinad.vi between Sound & Vibration Toolkit and Singal Processing Toolkit.
When the input waveform is single tone, the output is almost the same, but raises much discrepancy while a certain distribution of the spectrum. Does the sinad.vi have some limitation to the input signal? Did I miss some setting of the terminals? Hope someone can give me some suggestion.

How to acquire video from 3s vision IP camera

I was wondering if someone could tell me how to configure the vision acquisition, so I can acquire video from an IP Camera (3S vision IP Camera)?
I tried to use an IP camera dapter, but that didn't work. I currently can only acquire video from my webcam.
Can someone please help me out?
Thanks in advance!

Hi Nando88,
National Instruments only supports Basler and Axis IP Cameras as part of NI-IMAQdx. There is an IP Camera Adapter which emulates the functionality of a USB webcam. I assume this is the IP Camera Adapter you are referring to in your post. This adpater is not oficially supported by National Instruments and does not work very well for all IP Cameras. This adpater will help you stream video from your camera directly to LabVIEW, like in this example. If you want to acquire separte images you will need to use property nodes to take a screen capture, save that to an image file and then open that file as an IMAQ image. You have to go through all these steps because that IP camera is not supported by the NI-IMAQdx driver.
I hope this helps.
Cheers

How to acquire data from multiple dataports at the same time

Hi,
I studied the multithreading section of Labview, but still have no idea
how to make it work. Let me briefly explain my situation. I need to
develop a program that can control and acquire data from 4 serial
ports. I have 4 buttons to control starting or stopping acquisation
from the corresponding port. Every acquisation process is a while loop.
How can I start a new acquisation loop (eg. from COM2) while the loop
for COM1 is still running? In other words, I wish the 4 loops running
independently, and are controlled by their corresponding buttons only.
Thanks for any suggestion.
Jin

Hi Anonymous,
If I were you, I'd create one VI (call it Port.vi) to listen to one port - then make it reentrant. Drop 4 copies of Port.vi on your Main diagram. Port.vi inputs could include a VISA reference, a "Start/Stop" notifier and maybe a "Quit" occurance. Wire to each copy of Port.vi a unique VISA reference and a unique "Start/Stop" [boolean] notifier - let all the copies share the same Quit Occurance.
In Main, have one event case for each of your stop buttons. When a button is pressed, send the appropriate Start/Stop notifier!
... of course you could accomplish the same thing with four identical loops right in your main diagram, but the more complex the port-handling gets, the easier it will be to manage in one place instead of four.
Cheers!
When they give imbeciles handicap-parking, I won't have so far to walk!

How to acquire data from 2 chs of the same DAQ card at different sampling rate

I am using single DAQ card (either 6013 or 6014) in my system i want to acquire data from 2 (or more) channels with following requirements
1. sampling rate of each channel should be independant of each other (say one is 20 Hz and other is 15 kHz)
2. data from all the channels should be acquired simultaneously.
3. coding must be done using DAQmx VIs
I have tried out following things
1. I created separate task for each channel: i found out that two tasks can not run simultaneously even though the channels are different
2. I tried out single task with two channels included in it. and i used 'channels to Read' property to determine from which ch. i want to acquire data: this method works fine if the sampling rates are same. but if i change the sampling rate of one channel it gets reflected in other channels as well.
can somebody help me out to solve this problem.
i will appreciate if somebody can post the sample code as my deadline is approaching

How run reports JDE from BPEL using the Adapter for JD Edwards OneWorld?

Hi,
I need to load on line a lot of invoices from Bpel to JD Edwards using the Adapter for JD Edwards OneWorld (iWay).
Using Business Functions as Web Services it wasn't a not good idea because of this Adapter is poorly constructed and doesn't allow simultaneous loads, a memory leak occurs on JDE server. And to load them invoice by invoice is very slow.
A choice is to use Z tables and load them through schedules, but Bpel loses total control.
I heard that I can run processes reports that enable to extract the data from the Z tables and load them into JDE.
How can I execute reports JD Edwards invoked from BPEL using the Adapter for JD Edwards OneWorld?
Thanks

How to run report from form using run_object_report

I AM USNING FORMS9I/REPORTS 9I , HOW TO RUN REPORT FROM FROM USING RUN_REPORT_OBJECT AND HOW
TO PASS PARAMETER AS WE DID IN RUN_REPORTS PLEASE HELP ME

here an example !
I hope this example you can use it
PROCEDURE pr_reporte IS
BEGIN
DECLARE
     repid REPORT_OBJECT;
v_rep VARCHAR2(100);
rep_status Varchar2(20);
d1 DATE;
d2 DATE;
BEGIN
     d1 := :GLOBAL.DIA_INI;
     d2 := :GLOBAL.DIA_FIN;
     repid := find_report_object('rep_lab02');
     SET_REPORT_OBJECT_PROPERTY(repid,REPORT_OTHER,'p_fec_uno='||to_char((add_months(last_day(d1),-1) +1),'DD/MM/YYYY')||' '||
     'p_fec_dos='||to_char(d2,'DD/MM/YYYY'));
     SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESFORMAT,'pdf');
     v_rep := RUN_REPORT_OBJECT(repid);
     rep_status := report_object_status(v_rep);
     WHILE rep_status in ('RUNNING','OPENING_REPORT','ENQUEUED') LOOP
          rep_status := report_object_status(v_rep);
     END LOOP;
     IF rep_status = 'FINISHED' then
          WEB.SHOW_DOCUMENT('/reports/rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?'||'server=repserver','_blank');
     ELSE
          ventana('E','error reporte no encontrado','S');
     END IF;
END;
END;
The 'rep_lab02' is the name of the report that you give in the node reports
p_fec_uno and p_fec_dos they are the parameters in the report
repserver is the name of server created with rwserver

How to decode PCM from microphone?

I need to make clap recognition on iPhone.
I know an algorithm how to make it analyzing amplitude-from-time audio signal. But it's not clear for me now how to get such a representation of audio signal from microphone.
Now I only know how to write audio files from microphone:
recorder.h
#import <Cocoa/Cocoa.h>
#import <AudioToolbox/AudioQueue.h>
#import <AudioToolbox/AudioFile.h>
#define NUM_BUFFERS 10
typedef struct {
AudioFileID audioFile;

AudioQueueRef queue;
AudioQueueBufferRef buffers[NUM_BUFFERS];
UInt32 bufferByteSize;
SInt64 currentPacket;
BOOL recording;
} RecordState;
@interface recorder : NSObject {
@private
BOOL recording;
RecordState recordState;
@property(nonatomic, assign) BOOL recording;
- (void)start;
- (void)stop;
@end
recorder.m
#import "recorder.h"
@implementation recorder

if(val)
[self start];
else

recording = NO;
recordState.dataFormat.mSampleRate = 8000.0;

OSStatus status = AudioFileWritePackets(recordState->audioFile, false, inBuffer->mAudioDataByteSize, inPacketDescs, recordState->currentPacket, &inNumberPacketDescriptions, inBuffer->mAudioData);
if(status == 0)
recordState->currentPacket += inNumberPacketDescriptions;
AudioQueueEnqueueBuffer(recordState->queue, inBuffer, 0, NULL);
- (void)start {
if(!recording) {
self->recording = YES;
recordState.currentPacket = 0;
OSStatus status = AudioQueueNewInput(&recordState.dataFormat, AudioInputCallback, &recordState, CFRunLoopGetCurrent(), kCFRunLoopCommonModes, 0, &recordState.queue);
if(status == 0) {
for(int i = 0; i < NUM_BUFFERS; i++) {
AudioQueueAllocateBuffer(recordState.queue, 16000, &recordState.buffers);
AudioQueueEnqueueBuffer(recordState.queue, recordState.buffers, 0, NULL);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writablePath = [documentsDirectory stringByAppendingPathComponent:@"audio.aiff"];
NSLog(writablePath);
CFURLRef fileURL = CFURLCreateFromFileSystemRepresentation(NULL, (const UInt8 *) [writablePath UTF8String], [writablePath length], NO);
status = AudioFileCreateWithURL(fileURL, kAudioFileAIFFType, &recordState.dataFormat, kAudioFileFlags_EraseFile, &recordState.audioFile);
if(status == 0)
status = AudioQueueStart(recordState.queue, NULL);
if(status != 0)
NSLog(@"Recording Failed!");
- (void)stop {
if(recording) {
self->recording = NO;
NSLog(@"Stopping queue...");
AudioQueueStop(recordState.queue, true);

AudioQueueFreeBuffer(recordState.queue, recordState.buffers);
AudioQueueDispose(recordState.queue, true);
AudioFileClose(recordState.audioFile);
NSLog(@"Audio file closed");
@end
I have an idea to replace AudioFileWritePackets in callback AudioInputCallback. And that inBuffer->mAudioDataByteSize bites from pointer inBuffer->mAudioData will be amplitude-time signal representation... But I do not know how to decode that memory area: looks like I need to work with a pairs of bites (mBytesPerPacket = 2). May I represent them as one of "standart" types (like int)? Is it signed or not?

hi, Have you solve the problem ? I am interesting in this field too .
