DC Powered NI PXIe-1071
hello!
I am actually using NI PXIe-1071.The Input source is AC but my requirement is to power up my PXIe through DC Input.Can u suggest any power distribution solutions like DC-DC Converters or modules with multi voltage levels meeting the power requirements of PXIe.
Solved!
Go to Solution.
Will AC power not be avaialbe where you are using this chassis? The chasis powered by AC input as you stated. If only DC is available, you will need a DC/AC inverter to use this chassis.
Here are the Power Input specs:
Input voltage range................................. 100 to 240 VAC
Input frequency ...................................... 50/60 Hz
Input current rating................................. 4-2 A
Line regulation
3.3 V................................................ <±0.2%
5 V................................................... <±0.1%
±12 V .............................................. <±0.1%

The PXIe 1071 chassis is located inside a panel which is normally kept closed. Every day morning at start of shift, the operator has to open the panel door and switch ON the White button in front of the controller. This is something they are not happy doing as the panel does have high voltage switchgear at the bottom level.
Earlier with PCI boards and normal Induatrial computer we could wire the Power ON / OFF button to a switch outside the panel. Whihc was in parallel with the built in power switch of the PC.
I would like to get the same functioanlity with the PXI also, as noted below :
- When the panel is powered up, the PXI also powers up and loads the WIN7 OS.
- The operator launches the application and completes testing.
- When done he quits the application, shuts down the PC.
- Powers down the panel and goes home.
I have already treid to read the manual which talks of a SW1 switch but the description is quite ambigous as to what it does :
When switch 1 of SW1 is on, the backplane controls the power supply on/off state. This allows you to circumvent the controller and turn the chassis on/off manually. When switch 1 of SW1 is on, the power supply turns on when you press the front panel power switch....
I really am not clear as to what hey are trying to say. And since the system is now with client, I need to be sure before I propose to change default settings. Trial and error will look not so good.

LV2012 to Automate Hydraulic Test rigs.Hi Ming,
I apologize for my confusion regarding the functionality of the DB9 inhibit switch versus the white power button. I must have misinterpreted the descriptions in the User Manual. It seems that the white power button can hibernate the system whereas the DB9 inhibit switch just cuts off the power. In order to properly shut it down without using the white power button you will need to first hibernate or shutdown the computer through the Windows interface, then you can use the DB9 inhibit switch to remotely cutoff the power to the chassis and later turn it back on. I am not aware of another simple 'one press button' type way to remotely hibernate the PXI controller.
Since your chassis is located in a cabinet you could run keyboard and monitor cables to the device to interface with it. Alternately, you could connect the chassis to the internet and use Remote Desktop to shut it down.

Getting DataSocket for LV RT 5.0.0 installed on PXIe-1071?
Hello all,
Hopefully this is just an easy to answer question, but since I got so stuck on this I'll ask it anyway.
How do I install "DataSocket for LabVIEW Real-Time 5.0.0" (on a NI PXIe-1071 module with MAX)?
Installing software with MAX and getting it on they module is not the problem, the problem is that I can't find any setup file to download that has the specific program: "DataSocket for LabVIEW Real-Time 5.0.0".
The system we use is a:
- NI PXIe-1071
With the modules:
- NI PXIe-8100 (Embedded controller, Slot 1)
- NI PXI-7951R (FPGA with NI 5751 adapter module for flexrio, Slot 2)
- NI PXI-5402 (Function generator, Slot 3)
The software we have installed can be seen in the picture (Attachment) (And yes we also need to resolve the driver problem for the function generator in slot 3 as can be seen in the picture
All software in installed with MAX, all NI drivers have been updated in the last two days to the latest versions. A lan connection (with same subnet) connects our host computer with our NI PXIe-1071 box.
The reason we need the "DataSocket for LabVIEW Real-Time 5.0.0" is that we are creating a copy of a working existing system.
When trying to find it on the NI support pages we keep finding a page that directs to the page to instal NI LabVIEW Run-Time Engine 2012. After downloading and trying to install it we get this message: "Cannot install - NI LabVIEW Run-Time Engine 2012 f3 (higher version already installed)"
Thanks in advance,
Sander Breur

No power in new SC-2345, PWR01 (powered from PXI-6221)
I've used several systems in the past that included an SC-2345 box powered from a PXI card, and until now have not had problems.
I have an SC-2345 (PWR01, rear-connect) connected to a PXI-6221, all brand new, and the SC-2345 does not seem to be getting any power. The indicator LED's on the front do not light, and if I look at terminal 14 on the screw terminal block, I don't see the +5V I expect. If I unplug the 68-pin cable at the SC-2345 and look at the pins directly, I do see +5V on pin 14. All the pins on the cable appear in good condition, and the cable seats firmly when plugged in.
I can run a self-test on PXI-6221 from MAX, and it passes. I've removed all cartridges from the box and looked for obvious shorts, but the problem persists. There _may_ have been a short when the box was first connected -- a few leads from the front panelettes were disconnected and unrestrained. Supposing this caused a short, are there fuses in the box that I can check / replace?
I have spare SC-2345's, but it's a little difficult to get them to this particular site -- are there any suggestions for things to check before just trying a different SC-2345?
Thank you!
-EricHi Eric
Did you set the switch S1 on the SCC-PWR01 to select the source of the +5 V E SER (E/M Series) or EXT (external). If you select EXT, you must connect a +5 V supply (user supplied) to the screw terminals of J1 on the SCC-PWR01. For more information here is the link of the manual

Bluetooth connectivi​ty for PXIe-1071, PXIe-8133
Hi, There are about 24 numbers of NI PXIe-1071 chassis with PXIe-8133 controllers in our lab. I would like to interface a Bluetooth device (EEG and ECG monitors) with the DAQ. The DAQs are running Windows 7 and LabVIEW.
How would you suggest I connect the Bluetooth devices to the DAQs?
If I buy Bluetooth dongles that fit via the USB is that a good solution?
Thanks.
PhilipHi PKP,
Since your controllers are running Windows 7, they function just as a normal computer would; therefore the USB ports would behave just as a desktop would. You could load the drivers onto the controller and collect data from the bluetooth device that way. Do you have software to read the EEG and ECG signals into LabVIEW?
Best,

We have a PXIe-1071 and would like to upgrade the memory from the existing 4 GB. What is the maximum this board will support? I opened it up and found 2 SODIMM slots occupied by 2 GB. Will it take 4 GB sticks (for a total of 8 GB) or 8 GB sticks (total of 16 GB) ? The manual and NI page mentions nothing about RAM at all, but the page for the PXIe-8135 says it supports 16 GB.
If the spec say 8GB is your limit, then 8GB is your limit.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

PXI interference 25.5kHz
Hello,
I have a custom hardware setup with a PXI to assist with hardware control and data acquisition. The point of the data acquisition is to read in a signal from the hardware, do a FFT, and analyze 1kHz - 256kHz. The signals are small and near the noise floor of the ADC.
I got a continuous signal at 25.5kHz in all of my measurements. I used a spectrum analyzer to figure out where this signal was coming from. I ended up taking everything apart until I was down to only the PXI. The PXI itself was generating the signal and putting it all over the place (Even the casing).
What generates this signal on the PXI? Can I turn it off? It appears the instant the PXI is powered on.
The signal is quite strong, about -70dBm at the DAQ port. You can even find the signal on the ground of the SH68 connectors.
I've tested on two different PXI systems in two different places and its the same result.
System: PXI-8101e OR PXI-8135 (appears for both, seems to be stronger on PXI-8135)
PXI - 6115 (DAQ)
PXI - 6723 (AO)

Turn off the lights. Does it go away?
(Electronic ballasts in some florescent system can cause similar problems)
No, some of the tests were outside. I tested for environmental noises by making a big loop. I was catching some 10kHz noise on the loop that wasn't in the measurement, so if the 25.5kHz was from the environment it would show up there I would think. If the lights are corrupting the mains, its kind of disappointing this makes it through to the PXI, as none of my other measurement equipment receives that signal.
To be frank, it is disappointing that a signal measurement device has this signal corruption. It is unusable except for the most basic measurements, and people aren't going to sink this kind of money to get -50dBm noise floors. At least I've moved up a frequent flier class trying to troubleshoot this between the two locations. -
PXIe acquiring and disk streaming speed
Good evening,
I need to acquire and stream to disk the status of N.8 digital lines at 100 MHz clock, idest 100MBytes/sec data rate, in continuously mode (without data loss) for five minutes.
I've thought to a PXIe configuration with:
PXIe 6544 High speed DIO,
PXIe 1071 Chassis,
PXIe Controller with solid state H.D. option.
Is that configuration enough?
Thanks.
Natalino RobertoHello Roberto,
According to NI PXIe-6544 specifications, you should be able to achieve typical data streaming rates 400 MB/s for acquisition and 400 MB/s for generation. So, you shouldn't face with any issue from this side.
Does your application provide an host interface communicating with embedded application? If doing so, you may need to design your application according real time guidelines.
Let me know if you need help or additional assistance.
Have a nice day.

Where i can find exemples for PXI-2564 relay module
hello,
I'm beginner in PXI module using.
I bought a PXI solution for use it as a custom instrument.
My aim is to read RTDs and command some line using relays.
So i take the system below:
NI PXIe 1071
PXI-8100
PXIe-4357
PXI-2564
I can see all the material on NI MAX.
In MAX, i can read RTD a channel value and can operate relays.
i have read and practice exercice on "Getting started with Labview RT module" and all it works,But i don't find any resources or exemple to deal with relay card or read RTD.
I have try to access it using "visa connect" and this step works, but what must i do to go further.
In a first time i want to swap relay position, by reading position, invert value ,set position and return the value.
And for RDT i'll want to make a simple measure and make a average a N measure for 1 or all input.
Can you give me some exemple or trick?
Best regardsHello,
What software do you use? what version?
Have you look into the LabVIEW Example Research with KeyWord "Relay". There are examples with NI-DAQmx and niSwitch drivers.
Thanks

Where to find connectors for PXIe plugin card
Can anyone help with information about XP4/XJ4 connectors for PXIe: Suitable vendor type numbers?
We want to make a custom card to plug into a PXIe-1071 chassis - but only need the 3.3V power from the chassis. But after long search I was unable to find a type number for such a connector. XJ4 is the smallest but obviously any of the connector types will do as they all have power pins.
Solved!
Go to Solution.Hello heel.
I have searched in our internal papers, and according to my findings we are using ERNI as a manyfactor for our connectors.

Also, since you want to design for own PXI board, you might be able to find some usefull information in the PXI specifications.

Chassis PXI (question débutant)
Bonjour a tous,
Voila j'aurais une petite question concernant le développement d'application avec un chassis PXI.
Hbituellement pour la réalisation de mes banc de test, je controle des appareils "standard" mais la pour mon nouveau projet je me suis dit que j'allais passé par un chassis PXI-e.
Donc voila, je dispose d'un chassis PXIe-1071 équipé d'une carte scope, une carte géné et d'une matrice.
Comme je n'ai encore jamais travaillé avec ce type de matériel, je me demande quelle méthode appliquer pour développer mon application. Es ce que je dois installer l'abview directement sur le chassis PXI le temps du développement du soft et une fois le développement figé, créer un exécutable et désinstaller labview du chassis ou alors connecter mon chassis a mon PC habituel de labview et controler mon chassis a partir de celui ci? dans ce cas, serais je obligé d'installer les drivers de mes carte (scope, géné matrice) sur mon PC de développement habituel?
Ces question vont peute etre vous paraitres stupide mais comme je débute avec ce type de matériel j'aimerais avoir l'avis, la méthode de travail de personne plus expérimenté.
Merci d'avance pour vos réponses.
Résolu !
Accéder à la solution.Salut,
As-tu un contrôleur dans ton chassis (dans le slot de gauche) ? Si oui, l'utiliseras-tu sous Windows, ou sous OS temps réel ?
Si tu l'utilises sous Windows, installe LabVIEW dessus, sans quoi, tu n'auras pas la possibilité de visualiser les variables avec des sondes d'observation.
Une fois ton projet finalisé, la license de développement n'est plus nécessaire. Tu pourras donc la supprimer, et te contenter du moteur d'exécution de LVet d'un exécutable

PXIe chassis not communicating
I have a NI PXIe-1071 chassis with a NI PXIe-8360 controller and a EC card. The chassis also has a NI PXIe-2596 100 relay switch.
The power and link light are both green.
MAX does not "see" any PXI instruments.
I have installed NI Switch 4.4 and PXI platform services 3.0.4
Can anybody tell me what I am missing?
Solved!
Go to Solution.To better help you solve this issue; I had some of questions and wanted to confirm a couple of things.
Do you have the DAQmx Drivers installed, and if so what version.
When you say the “MAX does not see any PXI instruments”, I am assuming you mean that MAX does not even see the PXI chassis. Is this correct?
Are you starting the PXI before you start your computer?
Have you been able to see the device in MAX previously?
In the future you may find it easier to get a response if you post a question like this on the PXI Hardware Board

Hi all,
I am doing some tests with LabVIEW and I want to send analogic voltage signal to a PXI 6229 (the chassis is a PXIe-1071). I would like to know if I need to add, in the testing programs I have, any control to make the connection between Labview and the controler. For instance, to describe to which connector in the PXI 6229 the cable is connected to (it only has Connector 0 and 1)
Thanks in advance,
FranciscoHi again.
Thanks everyone for the solutions given. Everything was correctly made, but I was connecting the wrong cable.
I just would like to know another thing: I need to generate a signal using formula block (2 different ones: one with respect to the X axis and the other one with respect to the Y axis). My question is: should I create 2 DAQ Assistants, each one with a different output connected to a different axis, or is there any assembly block that allows me to assemble both formulas block and the connect it (the assemble block) to the "data" part of the DAQ assistant?
Best wishes,
Francisco
