What determines TEST PANELS to show or not...

On any fresh install of NI-DAQ, the System Administrator and the first user logged in afterwards can use the Test Panels... button in the "Measurement & Automation Explorer" as well as run the Standalone programs made by Application Builder (LabView 7.1)...all other users can not use the Test Panels... or run the Built-vi's that shows up with plenty of error code 21, "an external subroutine required for execution could not be found", and it seems to be vi's that are called by the vi's we use, like one step away. I have set the permissions to all the related files to FULL as well as hacked the registry's HKeyLocalMachine->Software->NI... as well as the CurrentControlSet->...->DAQCARD... all to full control.
Since the Administrator and the frist user can run the programs it is definitely not a case of missing software, but just permission rights. Please help to get the other users productive as well!

Hi Nambabwe, if the test panels button is greyed out for a device, that means that MAX was unable to load the nidaq32.dll driver. I am interested in figuring out this problem, because it seems to be a commonly reported problem, yet I cannot reproduce it myself. Here are a few questions for you:
* Which version of NI-DAQ are you using?
* If this version is equal to or greater than 7.0, do you have both Traditional NI-DAQ and NI-DAQmx installed, or just Traditional NI-DAQ?
* Regarding the non-administrative users who are running into this problem: are they restricted users, power users, or guest users?
Here's one possible solution off the top of my head:
The "CurrentFile" value of the registry key "HKEY_LOCAL_MACHINE\Software\National Instruments\NI-DAQ\CurrentVersion\Configuration Manager" indicates the location of the current DAQ configuration file. Ensure that your normal users have at least read access to this file (and this registry key too, but it sounds like you've already done this).
Please check back with the answers to these questions, and I will help to come up with a solution to this problem.

What determines the links that show up on my .mac page?

Just learning iWeb 1.1.2. I created a site that included a welcome page, about me, three pages of photos, and a movie page. All this was using the templates Apple provided. I renamed the photo and movie pages. I expected the Welcome page for the site to be the only one to show up on my .mac homepage. Instead, under My Pages, the Welcome page is the only one that does not appear. (Isn't it supposed to be the equivalent of index.html?) If I go to one of the listed pages, I can then navigate to the Welcome page. But I think that is backward from how it is supposed to work. Also, another site I created showed up at first, then went off the list when I tried renaming the photo pages (removing colons from the names and adding underscores in place of spaces).

OOOOOK.
Duh, now I understand.
If it's any comfort my .mac page does not show all the pages either. Never really paid much attention to it. Really not sure what that's all about. Sounds like a .mac issue , but don't think I'd worry about it as long as the site works.
By the way, the site looks good.
You might think about a page that shows references your albums with links to the pages. You can elect to not have the album pages in the menu bar. Keeps the menu bar from getting too cluttered. Looks like you had that sort of idea on you "about me" page, but no links.
08 incorporates this concept.
anyway, good luck. Looks like your having fun with it.

What determines who I "see" in in shared?

I have a macbook running 10.6.5 and have connected to an older macbook pro running 10.5.8. At the time, I was able to connect and use screen sharing etc. and both macs were on the same network at the time.
Now, I am on another network and can no longer see that macbook pro. I can however, see one of my other macs sitting on another network all the time, as well as another local mac on the network I'm currently on.
So, can someone explain to me what determines which computer will show up in my shared sidebar in the finder, and how or if I can get connected with that macboo pro?
Thanks!

As I understand it you cannot connect to computers on a different network node than the one to which you are connected unless you know the public IP address of the remote computer or the remote computer has a port opened to the internet. Back to My Mac is an example of a service in OS X that enables this via MobileMe.com, but you must have a MobileMe account to use it. Otherwise it is done, most conveniently, by using VNC (Virtual Network Computing) software such as the Screen Sharing application in OS X or a freeware utility like Chicken of the VNC. But to connect to any remote computer that computer must have an open port through which the software can communicate. When not on the same network that port will have to be accessible through the computer's internet connection.
There are other issues involved. Here's one article dealing with connecting to a home computer from work (or vice-versa) that explains some of the logistics involved.

Test Panel for 6704 no examples?

I'm trying to find an example vi that support our PXI-6704 card. Doesn't seem Ni has any built in, I'm wondering if "Getting started with analog output.vi" will work.
I don't deal with the programming or with the electronics so I'm out of the loop here.
In MAX were using a Remotei-daq config so making a test panel isn't possible.
I need a vi that acts like a test panel and shows what properties can be changed.
Any help at is all is welcome.

Hi JR,
There are lots of examples for this board. The PXI-6704
will function the same way as any other analog output board. If
you are using LabVIEW, then you can easily find a wealth of examples
that can run on the PXI-6704 by opening LabVIEW and going to
Help > Find Examples > Browse > Hardware Input and Output > DAQmx > Analog Generation
Once there you should be able to run any of these examples.
Best of luck,

3rd gen iPod Nano will not sync with latest version of iTunes. It passes the connectivity test but not the sync test under diagnostics. Worked fine on old Windows 7 laptop but not new one. From Control Panel it shows up as an Apple iPod USB Device...

3rd gen iPod Nano will not sync with latest version of iTunes on new laptop. It passes the connectivity test but not the sync test under diagnostics. Worked fine on old Windows 7 laptop but not new one. From Control Panel it shows up as an Apple iPod USB Device...

Never mind, I think. I think I figured it out. There was 1 song (out of > 900!) that somehow had been purchased with the other ID - I have no idea how. Once I deleted that song, it stopped asking.
There may be something with the newest iTunes version too. I didn't think in older versions that the "On this iPod" list of songs was greyed out. But at least it syncs ok.

When measuring 6 voltage signals in labview I found that there was a difference in voltage signals in my program but not in the test panel. The test panel is correct. What is wrong with my program?

My labview program is not displaying equivelent voltages, but labview test panel is. So the computer is seeing the correct signals. My program is displaying a small difference in 3 out of 6 channels. All channels should be equal.

G'Day Pops,
You haven't really given us enough to go on - could you please post your VI so we can have a look at it?
cheers,

DAQ card works with NIDAQ test panel but not with VB app/Component works

I am seeing this problem with 2 different DAQ cards. The card works fine with the NIDAQ test panel, but acts like the return lead is lifted with my VB app. The plotted signal appears to be little more than noise. Channel scan is internally triggered; that apparently works fine. The VB app is running in this configuration successfully in other areas, and I fixed this problem once by swapping cards. Currently, I lack a spare, as my "spare" is showing the same symptoms. Any helpful hints?
Card type: AT-AI-16XE-10
Configuration: Double-ended input, +/-10V range
Running: VB6, NIDAQ 6.1, ComponentWorks Std. 2.0.1, Windows NT 4.0 SP5

I upgraded to NI-DAQ 6.8.1 (with patch), but no joy. The upgrade went smoothly, the card was recognized and I was able to set the resources without a problem. The test panel works fine looking at the actual signal on the target system: slowly varying DC between 0-5 V or so. My app works fine also, except that it behaves as though the A/D is not connected to anything: noise between .05-.1 V or so. I swapped DAQ cards between the test system and my development system. The problem appears to be in the test system, not on the card. Another test system, identical except for (now) the version of NI-DAQ, works fine. I'm stumped!
BTW, why are there 3 DMA channels listed in the configuration for this DAQ? Do all 3 need to be assigned? I've run some systems
for years with only the first 2 assigned.

NI-DAQmx task works in MAX or DAQ Assistant test panel but not in LabVIEW

I am attempting to read a single AI channel from a PCI-6024E card via an SCB-68. I have created a NI-DAQmx Analog Input Voltage Task in MAX for this channel, sampling in contiuous aquisition mode at 100 kHz, 10000 samples at a time, with RSE terminal config. If I use the Test feature from MAX, the channel acquires data as expected.
In LabVIEW, I call this task using an DAQmx Task Name Constant. If I right-click this constant and select "Edit Task", the Daq Assistant opens and I can use the Test feature from the DAQ Assistant to see that the data is still being acquired as expected.
However, when I try to programmatically read this channel in LabVIEW using the VI "DAQmx Read (Analog Wfm 1Chan NSamp).vi", the VI returns a constant DC value of 500 mV, which I know is incorrect (I can monitor the signal across the two terminals in the SCB-68 with a DMM to know that the signal coming in varies as expected, and as I read using the test panels). This erroneous reading occurs even if I make a new VI, drop the task name constant on the diagram, right-click the task name constant and select "Generate Code - Example" and let LabVIEW create its own acquisition loop (which is very similar to what I already set up, using the "DAQmx Read" VI).
Any ideas why the Test Panels work correctly but the LabVIEW code does not?

Hello bentnail,
I'm not sure why the test panels are readin the value correcly but the LabVIEW code does not, but there are a couple of things we can try.
1) What happens if you just use the DAQ Assistant and place it on the block diagram? Does it read out the correct values?
2) Try running a shipping example that comes with LabVIEW. "Acq&Graph Voltage-Int Clk.vi" should work well.
3) What kind of signal are you expecting to read (peak to peak voltage, freqeuncy, etc.)?
Thanks,

For a 3.33v input, DAQ & MAX Test panels read 018v. What is missing in set up?

Hi All:
I am resurrecting a Labview setup that has not been used for a few years.
The goal is to measure strain.
Software is:
Labview 6.0
DAQ V6.8.0f9
MAX 2.0.3.6.
Hardware is:
PCI-MIO-16E-1
SCXI-1000 Chassis
SCXI-1121 Module
SCXI-1320 Terminal Block
As a fist step I decided to test the hardware using MAX.
I reset all of the SCXI-1121 jumpers to factory settings except the Filter jumpers.
Filter jumpers were set at 10kHz and I left them at that setting.
In MAX I followed the software procedures for setting up the PCI-MIO-16E, SCXI-1000 Chassis,
and SCXI-1121 Module (Module was found using the auto detect). MAX verifies the PCI-MIO-16E
card, and the SCXI-1000 chassis.
I verified that EX 0 thru 3 were 3.33v using a digital meter.
I then wired EX 0 to CH 0 and using the MAX Test Panel and the set up string of
ob0!sc1!md1!0
in the channel box on the Analog Input tab.
I expected to see a 3.33v reading on the test panel, but got a reading of .0184v
(I assume this means zero or is noise). The result is the same on channels 1, 2, and 3.
As far as my bifocals can tell, all cables are connected properly, and there are no bent pins.
I have re-verified the jumper settings per the SCXI-1121 User Manual. I have printed the
“Knowledge Base”, “SCXI Trouble Shooting Resources” and walked through them step by step
to verify the set up of hardware and software.
I have set up a virtual channel for each channel and used the DAQ virtual test channel
test panel, and I get the same result .0184v.
Anybody have any suggestions or clues as to what I have missed?
Thank You
Peter Waltz

Hello Peter,
If you are reading 0.0184V on your analog input, then it probably means that you are reading nothing at all.
This seems like a driver issue more than anything else. Make sure that you are the latest possible driver installed for this setup. Traditional DAQ 7.0 or 7.1 are compatible with LabVIEW 6.0 and should work fine.
Once you have the right driver, try connecting your analog output to your analog input. Output a sinewave or a specific voltage and see what the AI reads.
Most likely the driver upgrade would solve your problem.
You can download the drivers from here.

Correct termocouple reading by VI channel test panel but not by DAQ wizards.

1. I am getting correct termocouple readings when using the virtual channel test panel, but not when using labView software created by the DAQ wizards. why and how to solve it?
2. I am unable to switch on 6V relay using DAQ card's output voltage but able to do so using other voltage supply. How to solve this?

In answer to #2, the DAQ card's analog and digital outputs cannot drive
enough current to turn on a relay. What you need to do is use the output to
drive a MSOFET or transistor that will drive the relay. You can use the 5V
computer supply that is available on the DAQ card connector as the power
supply that the MOSFET or transistor use to turn the relay on.

Simulated device in MAX, self tests without error and has working Test Panels, but doesn't show up in DAQ assistant.

I'm trying to create a development machine where we can test new code without using our physical hardware. I've followed this guide in setting up a simulated device. I can get to step 3.2b, but the device does not show up in the DAQ assistant. In MAX, the device self tests and self calibrates successfully, and when I open the test panels, I see some sort of signal. I assume this is a default simulated input since I haven't told the device to look for anything? Note that the two devices I'm trying to create show up in the Devices and Interfaces section, but that even after running Self-Calibrate, the Self-Calibration date is still unspecified.
When I try to test the device and create a voltage input according to the guide, I am unable to see either device in the DAQ task creator.
Steps 1 and 2 of this guide are obviously satisfied. Step 3 is not, but this is unsurprising since a simulated device wouldn't be found in the Device Manager anyways. Also, I am not running RT, so step 4 is satisfied.
Does anyone have any ideas?
Solved!

That would be because the PXI 5124 is a digitizer not a analog input device. You need to use the NI SCOPE driver not NI DAQmx

Can not send command via VISA test panel in MAX

Hello all,
I am having a small issue using the VISA test panel in MAX. I am trying to send a simple command to a device and then retrieve the response data. I am able to do this successfully via Labview, but for whatever reason I can not get a good response in MAX. The command that I am sending is simply a letter (address of the device) followed by an end of line character (\r\n in ascii). In MAX, I simply append the \r\n onto the string sent in the buffer (Send End on Writes == FALSE). All serial settings are the same as what I have in LV (19.2, 8-n-1). Does anyone have any thoughts? This is kind of frustrating as I just want to do something simple and don't want to have to build a whole routine in LV to do this.
Cheers, Matt

Thanks, Broken. I am getting a time out error. Clearing the buffers doesn't seem to be making a difference. This is baffling to me. I must be missing something fundamental.
Something that I didn't add before is that I seem to be able to send the command via labview without a read, and then read it via MAX. This must have something to do with way it is sending the command. Arrrrgh!

CAN 8473 Not working with Test Panel in Max

Hello all. I am working with a USB-8473s CAN unit. I have it connected to the bus and can see the can traffic through the bus monitor. So everything is working properly there. I am trying to send a certain message so I set up a message and channel in MAX but when I go to the test panel I get an error saying that the "Test Panel cannot run since no CAN ports are available. Make sure you have at least one NI CAN card inserted into your computer". What is going on? I thought that the USB can unit was the CAN card? I'm on Win XP.

You're not going to like the answer. The 8473 only supports the frame API and not the channel API. No messages in MAX.
http://sine.ni.com/nips/cds/view/p/lang/en/nid/203384 >> specification tab >> API Support
I ran into this same problem.
You'll either have to use the frame API or purchase a different unit that supports the Channel API.

Hi, they have not got the application builder license here...

Why can i NOT use "differential" on the MAX test panel for channels 8-16??

I have a USB-6218
This is a 32 channel device with 16 Differential inputs.
Why can't i use the MAX test panel to view any channel beyond AI-7 using the Differential setting? It shades out differential even though my device has this capability.
WHY????

I am using MAX 4.1.0.3001 in conjunction with LV 8.0 and the USB-6218.
I go to MAX, Expand devices, expand MX devices, Right click on the USB-6218 (device2), and go to the test panels.
From there i am unable to view any differential pair beyond 8.
How am i supposed to Thru-Calibrate my equipment? Generally to achieve a valid calibration i use MAX itself to record the raw voltages the board "sees" as i apply known loads to the sensors.
The reason i need to check all this out is because DIFF pairs > 8 also are not working in my VI! Im am not sure if this is related or not.
