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.

My daq card PCI6025e' digital ports PA,PB,PC are in high state and cannot be changed even in MAX 2.1 testing panel and continuously output 5 volts even set for output.

my digital ports PA,PB,PC are in high state and cannot be set low even if it is set for outputs.
Thanks

The MAX utility is the closest to the driver level and will eliminate software configuration as a possible issue. Please disconnect anything that you have connected to the DIO lines.
Use the MAX test panel for your DIO lines, configure them as outputs, and set them to a low state. Use a multimeter (DMM) to observe the line state. If it is still high then you may have a problem with your hardware. If this is the case, I advise calling National Instruments support and investigate a possible RMA (repair).

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.

6025e MAX test panel

I'm using MAX test panel to test my digital I/O pins, however i couldn't find any manual explaining the function of the test panel. there are 2 tab on DIO. what are the operation/function in the 2 DIO tab?
First Digital IO tab
a. which port does it test?
b. why can't i select the input state?
For the second Digital IO tab
a. i can only select port 2,3,4, what does the port 2,3,4 refer to? coz for 6025E, i have only port 0,1,2,3
b. why can't i set the input i want for the input port?
c. how i check if the digital IO port is reponding?
thks & best regards

For the PCI-6025E, the number of the digital ports are :
0: DIO
2: PA
3: PB
4: PC
There is a big difference between DIO and the 3 other digital ports. While each line of DIO can be individually set to be a DI or a DO, all 8 lines of PA, PB or PC must have the same direction.
See the user manual for more information.
The first tab is used for the DIO port (DIO0 to DIO7). You can set the direction of each single line.
The second tab allows you to define one input port and one output port (eg PA (2) = DI and PB (3) = DO). You can then see the state of each line of the input port and set the state of each line of the output port.
You can easily test your hardware by wiring a DO line to a DI line (eg PA0 to PB0). Change state of DO and check if DI is co
rrect.

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,

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,

Test Panel in VI format

I am looking for the Measurement & Automation Explorer (MAX) Test Panel in a VI format. It has the ability to write or read from all lines in the DAQ. Each line is modeled as an LED.
I know that the test panel is available in the nitpan32.exe. I need to make some slight modifications to the file and was looking for it in VI format.

Greetings,
I am not aware of the existence of the Test Panel as a VI, but the example "Dig Multi-line Direction (E).vi" does accomplish what you have described. You can assign each line's direction, and they are represented by an LED (input) and a switch (output). This example is installed with LabVIEW.
Good luck with your application.

DIO won't work until I use the Test Panel

Here is some strangeness. A program that works fine all of a sudden has an issue on a clean install. I am using a DIO-24 and after the PC has been wiped and and the software including the OS and drivers are reinstalled I get an error trying to access the DIO. Once I open the MAX test panel for the device (DIO-24), wiggle some lines, and close it all is fine. The program will continue to function fine. What "Magic" is happening when I open the DIO-24 in MAX?

I am saying:
Are you saying that after installing the driver and your device you had to open MAX and use test panels before your device would work with your application, and now you can always use your application (even after restarting your computer) without opening MAX? - Yes
Does this behavior only occur with your software, or does it occur with a shipping example too? - I Have not tried to run example after a fresh install so don't know
Are you using LabVIEW to communicate with your device? - Yes LabVIEW 8.0
If so, what version and what driver have you installed. If not, what programming language are you using? - NI DAQmx 8.0 for Feb 2006 Disk
Is this driver version the same that you had installed when you developed your application? - No, previous version
What operating system are you working on? - XP
Do you need MAX open to run your application, or do you just need to run it before your application? - Just run once and close before running application
Any additional information you can provide about what you are experiencing would be helpful.
I spoke the the engineer who gave me the information and he said it happens only some of the time. Most systems come up fine but a few require that MAX before the app will run correclty.

Has to type each character twice while supplying command in Open VISA test panel

has a set of commands to work witha system connected to the MS windows PC. when I trype the commands in Hyperterminal (with/without ) they are yielding the expected results.
in LabVIEW, to get the expected results I MUST has to type 'each character' in the command Twice(except blank space) in the Open VISA test panel (viWrite/viRead). If I give the command is given the usual way(with each character typed only once), the result always is 'illegal command'.....the same works fine in the Hyperterminal.

What confused Ashwin is that you said "In LabVIEW". OK, so you're using the MAX test panel. There's one thing that's not clear. You said "when I trype the commands in Hyperterminal (with/without )". With/without what? How is your Hyperterminal session configured? Have you tried something like PortMon to see what's actually being sent from the serial port driver?

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!
Go to Solution.

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

I run a test print and its seamless. I reboot the Mini1 and run test print again and its good.
Now in Mini2 I did the same installation on shared printer but it is asking for user credential again and again, there is a check mark in "remember in keychain but still gives a notice that "requires authentication" I put the admin creadentials same with Mini1 then it prints.
every time I print on Mini2 its always asking for a user & password before Printing. How can we fix it.
I tried
- lpd printing = "authentication required"
- reset printer settings ang re-install printer = "authentication required"
- replace sharename in windows7, reinstall printer in Mini2 = "authentication required"
This stuff never happened to Mini1.

Error 10403 in Virtual channel Test Panel, but test pannel for device works fine

I am using a simple 10x probe attatched to the NI5112 PCI card. When the device is tested under the devices and interfaces part of MAX, I get the scope input, when I test the virtual channel for the scope, i get error 10403. How can i resolve this?

The reason you get that error is that virtual channels are not supported with our high-speed digitizers. Only devices that can be programmed directly with NI-DAQ support virual channels. The legal way to address a high-speed digitizer is by using DAQ::N, where N is the device number in MAX.

Differential input daq 516

I use the DAQ516 with a program derived from samples\easyio\ailog.c and ai_asyn.c with input single-ended :
In what way I can use the differential input ? What code i must to put ?
I use DAQ Card 516 , CVI 6.0 and Windows XP .
Many Thanks .

Hi,
The board you are using is only programmable using NI-DAQ Version 6.9.3. The device configuration is done through the Measurement & Automation Explorer (MAX). Under Devices and Interfaces you should see the Device listed. Right click on it and select "Properties...". You will get a popup screen with different Tabs
- General> You can configure the device number and test resources for the device
- Analog Input (AI) > you will be able to configure AI mode (Differential or Single Ended) and the polarity if available.
After the config is done, apply your differential signal to one of the 4 Diff channels that are represented by the couples: 0,4 1,5 2,6 3,7.
This should take care of your problem.

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.

I am trying to configure my SCXI-1540 card for excitation voltage and frequency using MAX - but it is not giving me that option when I click on the card and then properties, am I looking in the wrong place?

I am trying to configure my SCXI-1540 w/1315 card for excitation voltage and frequency using MAX - but it is not giving me that option when I click on the card and then properties, am I looking in the wrong place?
I have LabVIEW Express 7.0 Professional - SCXI-1000 Chassiss - along with SCXI-1112, and SCXI 1520/1314 - cable to the PCI-6052E is attached to the 1520 card.
MAX says it recognizes all the cards in the chassiss.

Jeremy, Thanks for the reply.
I tried to set up the system as DAQmx.
I had MAX auto-detect the set-up - and it recognized all the cards - but did not select the 1315 accessory on the 1540 card - I had to do that manually - but in the configuration section I would select the accessory and it would deselect itself. I had to get out of the set-up and then right click on the 1540 card and click on the "Accessories" tab and select the 1315 terminal block that way.
It didn't seem right that the system should behave that way, but I pressed onward.
I then tried to create a new DAQmx Task
When I create new DAQmx task and then click on Analog Input no "Position" Tab appears for me to select, all I get are:
Analog>>Voltage
Analog>>Temperature
Ana
log>>Strain
Analog>>Current
Analog>>Resistance
Analog>>Frequency
Analog>>Custom Voltage with Excitation
Do you think there might be something wrong with either my hardware or perhaps my configuration that is not allowing it to recognize the 1540/1315 in DAQmx?
I had included the system report of what programs I am using, etc. as attached file nireport.txt
After the DAQmx did not work I tried installing everything as Traditional DAQ and it did let me set-up the 1540 Card with Excitation Voltage and Frequency and gain - I then went in to the VI that I had built and tried to use the Express DAQ Assisant to read the channel that I am connected to on the 1315/1540 - when I try to use DAQ Assistant it gives me an error saying that "Device not available in NI-DAQmx. It is possible that the device is being use by traditional NI-DAQ"
Which I guess it is since both configurations are now set-up in MAX.
I would PREFER to use the DAQmx set-up, but I am confused as to WHY it won
't come up with
Analog input>>POSITION>>LVDT
When I try to create a new DAQmx task.
Thanks for the help so far! As you can probably tell I am new at this.
