Non National Instruments DAQ Boards

How do you configure (add) a non-National Instruments DAQ board, which is compatable with labview (IOtech DAQBoard 2000 - PCI), in the "Measurment and Automation Explorer" for LabVIEW? It currently does not display that the device is seen under the "Devices and Interfaces" section. All necessary software for the board has already been installed. Any help would be greatly appreciated.

Hi,
MAX is a program from NI, to configure and test NI boards, it is not meant to use with boards from another manufacturers.
You should use tools that should be available from your board manufacturer.

Measure Frequency of Digital Signal from DAQ-Board

I'm using a National Instruments DAQ board and I need to measure the
frequency of a digital signal from my data acquisition board.
I know the measure frequency.vi (In diagram - data acquisition -
counter), but i don´t understand yours implementation mainly in input
"counter". Because i don't understand the relationship of board channel (for
signal acquiring ) and the measure frequency.vi.
Thanks in advance,
[email protected]

Hi,
Attached is a vi which models your signal, and provides a way to measure the average frequency over a window of time. It converts the signal to a sequence of periods. I usually start with this approach because you can save the data in a much more compact form if your sampling rate is high. Obviously over a specified period of time, if there are no zero crossings the frequency is zero, so I was a little incoherent before. The real issue is the latency caused by averaging. Your frequency measurement is most accurate half your window size before the current time, so smaller windows give you more up to date measurements, but also more noisy. If you need the most up to date measurement, then you have to use the time since the last crossing which is the case where the frequency never goes to zero. That's probably not a realistic situation. If you needed less latency, you could use a prediction algorithm.
Also, there are a number of signal measuring and processing vi's that LV gives you, for instance pulse measurements that could be used to partially implement this or other approaches, but I normally steer clear of them unless they fit exactly due to having to convert back and forth to the waveform data type.
Have fun!

Does National Instruments produce a DAQ equivalent of an electronic load for fuel cell testing?

I am trying to consider my options before purchasing an electronic load. I would like to use LabView software to record and analyze my data that I will be generating during fuel cell testing. I was just wondering if National Instruments produced an instrument similar to an electronic load or a couple instruments that could work in combination similarly to an electronic load. I have looked through the available DAQ instruments on the NI website and it seems that they all output signals too low for my application. The fuel cell I will be using outputs voltage from 0-2VDC and current from 0-4A. I understand the internal workings of an electronic load and realize that the best option would be to implement some sort of variable resistor to act as the load in my circuit, then use DAQ instruments to measure current and voltage respectively. The problem is that the range of my current, especially, is much larger than any allowable input range for any NI DAQ instruments.
Any input would be much appreciated. Also if you have developed a testing system for fuel cells or other low power DC sources, please share any knowledge and information about how you went about designing your system.
Thanks

We used a DC Programmable Electronic Load from AMREL.
WE used GPIB to talk to each of them The loads ley us set constant current/voltage and let us query the current values etc.
Worked fine for us,

Using Labview on a non-daq board device

How would one go about using a device, connected through USB, in labview that doesn't have a daq board? I have a signal monitor that I've managed to get to work with C++ and was wondering if there was a way to integrate it with Labview at all. I hope that makes sense.

If they've provided a DLL then you can use the Call Library Function Node to call the DLL. You should read the chapter in the LabVIEW Help on calling code from external languages. If it's a C++ DLL you may have problems because LabVIEW only supports C DLL, not C++. A common issue is name mangling. If you do a search on the NI site for "DLL name mangling" you will come across several Knowledge Base articles that discuss this issue. Another common problem is that if the DLL uses complex datatypes (such as structures with strings inside, or pointers to complex structures then you will need to write a wrapper DLL that converts simple datatypes that LabVIEW can handle to the complex datatypes that the DLL uses. Again, there is a wealth of information on the NI site on calling DLLs, so a search will yield lots of information.

DAQ board no longer showing up in MAX, nor elsewhere.

I can no longer see my DAQ board in MAX, nor LabVIEW 7.1. It's a PCI-6023E, which was working fine last week.
I tried reinstalling MAX through the Control Panel >> Add/Remove
Programs, but it is not there. In "Add/Remove Programs", II click on
"National Instruments Software", but that causes my computer to hang.
I tried downloading the latest NI-DAQ, but it thinks it has nothing to
install. I explicitly use it to remove LabVIEW 7.1 support, then
re-install it, but my DAQ board is still invisible.
How can I communicate with my DAQ board again?

Hello Bmihura,
There is a utility called MSIBlast that can be used to remove software
from your computer when the Add/Remove Programs does not work.
For future reference, it sounds like some portion of your National
Instruments software has become corrupted during an installation.
It is important to strictly follow installation procedures outlined at
http://www.ni.com/support/install/
. Also, if your device does
not show up in MAX, it probably is a result of an incorrect driver
installation, and not a problem with the MAX program.
The first thing you will want to do is remove the hardware from your
computer. Then, to get the MSIBlast utility, copy and paste the
following in an Internet Explorer web browser window:
ftp://ftp.ni.com/outgoing/
Find MSIBlast.exe and drag and drop it onto your desktop. To run
the utility, simply double-click on the executable. In the dialog
box, make sure you have 'Show NI Installers Only', and you should see
a list of National Instruments software installed on your
computer. Go through the list and select the components that you
wish to remove and click the 'Uninstall' button.
Once you have uninstalled all of the software that you could not
uninstall through Add/Remove Programs, restart your computer and verify
that everything was uninstalled through Add/Remove Programs. At
this point, if you chose to uninstall LabVIEW, that should be the first
thing to reinstall. Otherwise, go ahead and reinstall DAQmx
8.0. I would recommend re-downloading it from our website here
just in case the installer became corrupted during the download
process. After the driver is installed, now is the time to power
down your computer and physically install your hardware in a spare PCI
slot. When you restart your computer, Windows should recognize
new hardware and you should allow the wizard to install the driver
software automatically.
I hope this helps, and if you have any further questions you can either
reply to this post or directly contact an Applications Engineer by
calling 1-866-ASK-MYNI.

I want to run my program with continuous aquisition and write data to file when a button is pressed and get the most recent samples from the DAQ board.

This is an update to a question I asked earlier. I am still trying to solve the problem. I have included a zip file with a library file. The file to open in pj_pushbutton.vi. I have placed comments explaining the issues and problems in this vi and the subvi's.
When I push my button to write the data to file I think it is writing the data that has already been stored in the buffer and writing to file all at once. I want the data that is taken from the DAQ board from the time that I press the Write File button. How do I do this?

Hi,
1. In AI read, you need to set the Read/Search option to "Relative to End of Data".
2. Next you should not start AI Read VI until you press the Write to File. I am attaching an example VI below. Please see if it helps.

National Instruments PXI with IEEE 802.15.4 standard (ZigBee)

Bonjour,
En fait, je travaille sur un projet qui a pour but d’implémenter un émetteur/récepteur Zigbee en bande de base reconfigurable sur la plateforme d'évaluation XUPV5-LX110T qui embarque un Virtex 5. Je suis actuellement dans la phase de test réel.
Premièrement, Je veux envoyer mes données venant d’un pc vers un FPGA et de les recevoir (pour traiter mes signaux sur Matlab). Est-ce-que cette tâche est faisable ou non ? Y a-t-il une solution pour ça en utilisant un média de communication (la liaison série par exemple)
Deuxièmement, Y a-t-il un équipement de mesure et de test de National Instruments à l’aide des PXI qui supporte le protocole sans fil Zigbee ou autrement la norme IEEE 802.15.4 (à savoir RF Vector Signal Generator et Vector Signal Analyzer) de la partie frontale analogique que ce soit en émission ou en réception?
Et merci d’avance pour tout le monde.
Hello,
In fact, I'm working on a project which aims to implement a reconfigurable Zigbee tranceiver on XUPV5-LX110T Evaluation platform which integrates a Virtex 5 FPGA. I am currently in the phase of real test.
First, I want to send my data from a PC to FPGA and receive it (to treat my signals on Matlab). Is this possible or not? If yes, Is there a solution for it using a medium of communication (e.g. serial link)
Second, is there a measuring equipment and testing National Instruments using PXI which supports the Zigbee wireless protocol or otherwise IEEE 802.15.4 standard (i.e. RF Vector Signal Generator and Vector Signal Analyzer) of the analog front-end either in transmission or reception?
And thanks a lot in advance for everyone.

Hello,
I am not sure what data you will be collecting, or how you intend on using the board. Perhaps you can explain your application a little bit more?
Is the FPGA code already developed for your application with the XUPV5-LX110T board? As long as the developed FPGA code is able to communicate with your PC via whatever protocol you choose, then you can use that as a channel to send data back and forth. Since the board is capable of many different I/O connections, you can pretty much sending/receive data over which ever connection you prefer, Ethernet, RS-232, etc.
Just to clear up any confusion, if you do not already have FPGA code for the board, this is not something you would be able to develop with LabVIEW FPGA programming. The XUPV5-LX110T board is not supported for programming its FPGA using LabVIEW FPGA. You can however, program in labVIEW to communicate data back and forth with the I/O you have chosen to connect with to your PC, such as Ethernet or RS-232, as mentioned above.
As far as measuring equipment NI offers for testing with the Zibee (IEEE 802.15.4) wireless protocol in the PXI platform, if your application requires you to both transmit to, and received from the board, and then you would need either both a Vector Signal Generator and Vector Signal Analyzer, or a Vector Signal Transceiver. See the list below for some examples of what we have to offer.
VSAs: NI PXI-5661, NI PXIe-5663E
VSGs: NI PXI-5671, NI PXIe-5672/5673E
VSTs: NI PXIe-5644R/5645R/5646R
From my knowledge of ZigBee, you would be capable of communicating with the board using any of these devices.

DAQ board recommendation

Greetings,
I would like to use Labview to control an MKS Instruments 247D control box, which in turn controls four mass flow contollers. The 247D has a 25 pin port on it for this purpose, the pin out diagram can be found here:
http://www.mksinst.com/pin247d.html
and the relevant product data sheet here:
http://www.mksinst.com/pdf/mfcontlr.pdf
It looks as though I need four 0-5V analog outputs (for the setpoint inputs), four TTL outputs (for the flow on/off inputs) and four 0-5V analog inupts for the transducer output. Could you recommend a product (presumably a DAQ board) that is well suited to this application? I should mention, I'm fairly well versed in (and a big fan of)labview, but have limited experience with DAQ boards and the like. Also, I would ideally like a USB device so that I can easily control my system from my laptop. Thanks for any advice you are able to offer.
-Adrian

As George stated, the best thing that National Insturments has to offer you to satisfy your requirements are the new M Series and USB devices. I thought I'd give you the exact recommendations on what you'll need.
If you're set on using USB, then go with the NI USB-6015. If you think you might need additional digital I/O in the future, the USB-6016 might be a better suit. With either the 6015 or 6016, you would need to get two devices.
If you're not set on the USB bus, then a single M Series device can easily get the job done and leave you with plenty to spare. The three devices that you could consider are the 18-bit, 625 kS/s, PCI-6289, 16-bit, 1.25 MS/s, PCI-6259, and 16-bit, 250 kS/s, PCI-6229. Each of the devices have the same line-up of I/O - 32 AI, 4 AO, 48 DIO, 2 CTR - but they all have different specifications and features.
What you should do is figure out what specifications are the most important to you and begin narrowing your choices based on those. If USB is the most important, then M Series won't cut it. If, however, you're not tied to the USB bus, then what's the next most important. Generally, one of the most important specification is accuracy. If this is true for you, then I encourage you to read up on the 18-bit devices and see how the unique features make it the world's most accurate MIO DAQ device.

Not receiving any signal input with LabVIEW SE, USB DAQ board

Hello all, good afternoon.
I am having a little trouble with my DAQ device, I hope that someone will be able to help me.
I'm plugging a BNC pH sensor to a NI USB 6251 M-series board, to try and obtain the electrical response of that particular sensor, measuring the voltage output for each buffer solution (pH 4 and 7). Have 9.2.3 mx (lastest) drivers.
The pH sensor (floating) is plugged through a female BNC plug to the circuit board, signal is going through a signal conditioning circuit (composed by a voltage follower on each of the wires to lower the output impedance of the sensor, and 2 bias resistors from AI+ and AI- connected to AI GND with the board case wired to the power supply ground, as seen in http://zone.ni.com/devzone/cda/tut/p/id/4494)
I'm measuring in differential mode, as I said both wires of the sensor are going through a voltage follower each, and into the DAQ board. The Op-amps are being powered by +-15v as seen, again, in http://zone.ni.com/devzone/cda/tut/p/id/4494
I did take the time to read the manuals and tutorials I found, did quite a bit of investigation over the last few days, and wired the system carefully.
In labview signal express, I choose to take an analog voltage read, and select input range from -500mv to 500mv, because the sensor should output at most -400mv to 400 mv
Now, much to my dismay labview registers in that channel absolutely nothing, only a little noise (~1 mV). I unplug the sensor and realise that whether the sensor is connected or not, it doesn't make a difference in the presented output - it's as if it the sensor wasn't there at all. And yes, I am measuring the correct channel. I tried connecting the wires to different AI channel pairs as well, could be a faulty one, but no success either.
If I plug a voltimeter to the wires that are going into the analog inputs (after conditioning), it measures about 50 mV, which is a lot more than the 1 mV the board is measuring, but a lot less than the ~180 mV I should be measuring with a pH 4 buffer solution.
I know for a fact the problem is not the sensor, and the DAQ board seems to be fully operational.
I think it might have to do with the signal conditioning I'm doing, or some sort of configuration with the hardware of the DAQ board.
So, any idea what I might be missing?
I'm a week behind schedule because of this, hopefully I will find my answer here.
Thank you very much in advance!

Good afternoon.
Yes I have tried all of that. The board responds very well when a flat 5V DC voltage is fed into a channel.
However after much investigation I believe to have found the problem yesterday, it probably has to do with the operational amplifiers I was using. The input bias current was in the magnitude of nanoAmps, while for pH measurements an IBC of picoAmps or less is necessary due to the high impedance of the sensor. This was causing a drift of over 100 mV on my output which is about 2 pH and thus unnacceptable (even though I had the Bias resistors at the input to ground, like suggested in the NI tutorials, but apparently they were not enough to compensate for the high IBC).
In the lab all available op-amps suffer from this, even Instrumentation op-amps like AMP04 from Analog Devices. I still haven't had a chance to acquire new op-amps with the necessary IBC but hopefully it will do the trick. Makes sense since I checked the datasheets for every op-amp in the lab, and they all had IBC around 400 nanoAmps (and none of them worked), while every single op-amp for every pH meter circuit I found have IBC's of pico/femtoAmps.
The sensor I'm using is from AquaMedic, I'm not sure what the model is, but it's a cheap plastic sensor that comes bundled with their pH Computers.
Thank you very much for your input.

Synchronisation of frame grabber and DAQ board

I want to aquire images and analog voltage signals at the same time, and synchronised, using a NI PCI-1428 Camera Link frame grabber and a NI PCI-6014 DAQ board. Can this be done using the RTSI trigger functions? I know that the frame grabber supports this, but what about the DAQ board?
How about synchronising a NI-board with a non-NI frame grabber?
Thanks a lot!
Peter

Hi, Peter,
No, the PCI-6014 DAQ board does not support RTSI. However, most of the low-cost E-series NI data acquisition cards do support RTSI, such as the PCI-6024E or PCI-6036E, so you might consider using one of those boards instead.
If you decide to go that route, there is a useful tutorial that describes the signals that can be routed over RTSI for NI DAQ and IMAQ boards:
Developer Zone Tutorial: Synchronizing Motion, Vision, and Data Acquisition
as well as several example programs:
Developer Zone Example: Integra
ting IMAQ and DAQ with Single Display
Developer Zone Example: Low-level Triggered Ring (with DAQ-supplied triggers)
As for a non-NI frame grabber, that would really depend on what support the frame grabber has for timing and synchronization. You could route a trigger signal or scan clock out over the PFI pins on the PCI-6014, but you would need to see if the frame grabber is designed to receive these types of signals.
I hope that helps!

Analogic acquisition with Labview and National Instruments card

I need to acquire 2 analogic signals simultaneously. I use version 4
(maybe 5) of Labview, with a National Instruments data acquisition
card (BNC-208x). I want to save the 2 signals in a text file. Does
anyone could send to me a diagram (vi) for doing that.
Thank you very much.
(my email: [email protected])

True simultaneous sampling is possible with only a few types of DAQ cards. I believe BNC-208x is like the current BNC-2xxx series and is nothing more than a adaptor to the actual DAQ card inside the PC. If you can live with the small delay between channels that the majority of DAQ boards has, then there are a number of shipping examples that can help you. Look for the Cont Acq&Graph examples and Data Logger to Spreadsheet File.

DAQ boards substitutions

Hello,
Some years ago I have developped an application for acquisition built for
the acquisition board AT-MIO-16E-2. It is a LabVIEW 4.1 32 bits
application.
Now my customer asks if he can replace the board with the low cost PCI 6024E
(the sampling rate reduced to 200kS/s is sufficient for the application).
I wonder how will react the application with a different board and a newer
version of NI-DAQ. If any problem is to be expected, I doubt that the spared
money can compensate for the time and money spent for any modifications,
even minor.
Any advice?

well as far as i know, if he installs NIDAQ 6.5 or 6.6, it should be OK because 6.5 and 6.6 has CIN which were changed to DLL calls in NIDAQ 6.7.0 and later.
If you have the souce code, it will be easier if you recompile the code under LabVIEW 5/6 and NIDAQ 6.9 and distribute that to customer. That way your customer has to install the new board and latest driver and run EXE.

How do i read out the actual voltage range of the daq board as calculated by labview based on my input voltage range

I am somewhat new to DAQ so I hope I describe this well enough, but I have encountered a requirement for my VI that I am not sure how to obtain from LabVIEW. It is my understanding that when using a DAQ board (I'm using a PCI-6034 E) you can specify the voltage range you expect from your measurements, and then the software calculates the actual voltage range it will be measuring to ensure that you get the best resolution in your range that you can given the voltage step size, etc. of the equipment. I know how to extract the voltage input that I enter into the virtual channel, but I was wondering how I can extract the actual voltage range that the hardwar
e/software is using based on its own calculations from my input. Can anyone help me with this?

If I understand correctly, you want to retrieve the actual gain value (and, therefore, usable input range) used by your DAQ card for a particular measurement.
I think there's a good KnowledgeBase entry with your solution entitled "Programmatically Determining the Gain Used by a DAQ Device". Here's the URL:
