Hi,
I have followed the installation procedure for PXI 5404 from the starting guide. It shows present in my PXIe 1062Q chassis. However, i'm not seeing the soft control panel for it. The access LED with the card is also not lit.
Would you please help me to figure this out?
Thanks.
Greetings,
Need to confirm if the PXI-2541 is able to close relays kr#iso and kr#out at the same time or is kr#out always isolated from the input during normal operation.
See picture for relay locations.
Thanks,

Why not use all channels？Related theory?
Dear all,
I have a PXI-1033 chassis along with 2 PXI-6259. When I load NI MAX, I can see that there Windows cannot find drivers associated with both PXI-6259. Any idea how I can fix this?
Thanks a lot in advance.

I am new to PXI, I have a general question:
I have a notebook with LabVIEW 2017 Professional and windows 10.
Then I have a PXI-1078 Chassis with PXIe-8820 Controller and a few PXI cards .
I turned on the PXI Chassis, connected with its own usb mouse, keyboard and Display port to a monitor.
I noticed that it boots into a normal Windows 7 32bit OS.
It has no LabVIEW development installed, but only NI runtimes (VISA, etc...).
The goal of this PXI is to test electronic boards with a bed of nails.
At the end the final system will be a ATE (Automatic Test Equipment) that will be shipped to a contractor that will use it to test thousands of electronic boards.
So my questions are:
Thanks
Can you provide the MTBF ratings for the following hardware?

I have a further accuracy question. For the PXI 6363 I am thinking of a configuration where I want to maximise the resolution over a narrow range of voltage. For this, I think I could use the APFI 0 or 1 pins of the 6363 to provide a suitable external reference
But although I get accuracy specs for the internal voltages, what will affect the accuracy of my outputs driven using the external reference (except the accuracy if the reference itself)? This might be asking what components lie between the APFI pins and the external output, but I'm just keen to understand if my resolution might be swamped by accuracy problems
Hi,
I'm installing the PXIe 4113, downloaded the driver software from NI website. Whenever i'm getting to install it, it shows following error.
What should i do now?
I am new to LabVIEW, and so am trying my best to figure it out but I am having trouble. I am using the NI PXI-6133 S series device.
I have two AI Voltage channels and I need to trigger both channels, with pre- and post- trigger samples for both, whenever either one meets its individual trigger condition. I have successfully been able to trigger both channels with just one as the trigger source, but ultimately I need to be able to use all of the channels as trigger sources.
It seems like I should be able to do this with Reference Analog Multi Edge Triggering, according to the DAQmx 19.0 Manual: "[...] you can configure multiple channel sources acquiring in the same task to each have their own analog trigger condition. When any of the multiple channel sources satisfy their respective condition, a trigger is generated and the device will perform the specified action associated with the trigger." But when I tried this (vi attached) I got the following error:
-200077 at DAQmx Reference Trigger (Analog Multi Edge).vi:
Possible reasons: Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.
Property: Ref.TrigType
Requested Value: Analog Multi Edge
Possible Values: Analog Edge, Analog Window, Digital Edge, none
Additionally, I read here (https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000004A09SAE&l=en-US) that an AI channel cannot be used as the reference trigger source when you need pre-trigger samples for multiple channels, which is what I need to do. It says that the PFI needs to be used as the trigger source instead. But that is only for E series devices, whereas I am using an S series device. I read something similar here (http://www.ni.com/documentation/en/ni-daqmx/latest/devconsid/anltrigeseries/), which also says that with more than one channel being used for the reference trigger the PFI needs to be used instead of AI, but again, this is in reference to E series devices.
So, I am not sure if I need to change something in my vi in order to get the Multi Edge triggering working, or if I need to use the PFI rather than just the analog inputs, or if there is a completely different way to achieve this. I have been trying to work this out for a few days now but I am a bit lost at this point. Any help would be greatly appreciated.

I try to execute an example of national instruments, to be more specific, the example of MIL, this tutorial that I found on you tube and was loaded by national instruments, running it on Windows as a controller, there is no problem, the problem arises when I try to to run on a PXI 1042 in real time, I've already installed veristand in pxi,also LabWindows 17 RT
I have
veristand 2018 spi
labview 2018
NI PXI 1042
LabWindows ™ / CVI Run-Time Engine for RT 17
The link in the example is as follows:

The error code is 307703
Hello,
I am looking for pinout's and color code by pair for the following cables: 782417-03 and 779038-02. I need to confirm which wires inside are which color and connect to which pin on either end. Also to see if/how they are grouped and/or twisted. I am running from one PXI card to another, then to a switch card and back out to a DUT Tx and Rx. I need to know if I can use these cables, or if I have to just order the connectors and do my own discrete wiring. Thank you.
我之前使用的是USB的采集卡，使用文件IO将数据实时写入本地文本文件中，现在换成PXIe后（使用网线连接），将VI载入到远程系统下，文件IO打开/创建/替换不识别文件路径。我的理解是，VI载入到远程系统后，无法识别上位机PC硬盘路径，是不是需要在本地系统中建立一个VI用来接收数据，再写入PC硬盘。但是完全不懂怎么操作，有没有例子或者方法解决。
先谢过！
PXI-6221: What are the functional differences between the 779113-01 and 779629-01 part numbers?
Thanks!
I have a PXI 1042 chassis that appears to power On when the power switch is depressed, however, the power switch LED does not illuminate. Is the power switch LED a user replaceable part or does the whole chassis need to be sent back to NI to be repaired.
The system setup is:
1. PXI-1033 chassis
2. Slot 2 - PXI-4462(DAS)
Slot 3 - PXI-5412 (AWG)
Slot 4 - PXI-4472 (DAS)
We are measuring 5Hz - 25kHz. We are particularly interested in the phase difference between the 4462 & 4472 measurements.
I need to synchronize the 4462 & 4472. Is this possible with this setup? My understanding is that the PXI Chassis 10MHz clock must be used for both te 4462 & 4472 and the Star Trigger is also required. I think I read that the DAS must be both in slave mode for this to work. How could I accomplish this? Is there a labview DAQmx example available? thanks
I have several PXI cards where the backplane connector has been damaged and will not fit inside a PXI mainframe correctly.
Does NI offer a flat rate repair service for simply replacing that connector? If so, what is the cost?
Thanks!
Hello,
I am trying to synchronize the output of a SMU (PXI-4139) to the acquisition on four channels of a DAQ (PXI-4462), they are in a PXIe-1077 chassis with a PXIe-8133 embedded controller. The other slot in the chassis currently holds a PXI-4461.
In the past, we have successfully synchronized the output from the DAC on the 4461 to acquisitions on the 4462, by synchronizing the clocks to the PXI_CLK10 and exporting a start trigger from the 4462 to the 4461.
However, now that we want to drive the experiment through the SMU (4139), I am encountering issues. Explicitly, I want to trigger the start of an NIDCPower sequence from the start of an DAQmx analog input event. In essence, the SMU is being used as an arbitrary function generator for either current or voltage, and we are measuring the voltage response at four points in the system. The measurements can be quite short and proper synchronization is key.
I cannot find a means to synchronize the clocks. Is that possible? Even in trying to do a less-thorough synchronizing job, my attempts to export a start trigger from the 4461 to the 4139 have all failed. I tried to route the ai/starttrigger from the 4462 to the digital edge for the 4139, which did not seem to trigger the 4139 at all. I also attempted to route that start trigger through the back-plane manually, but that did not seem to work either (perhaps I did it wrong?). The best I seem to be able to do is have LabView start both the NIDCPower and the DAQmx events at the same point, which ends up with between 20-50ms of delay, far from what could be done with reference clock synchronization.
I have looked through the help files and boards pretty extensively, but if anyone has additional suggested reading or can point me towards other working solutions it would be greatly appreciated. If some VI screenshots would help, I can try to provide them - the overall code is quite complicated so I was not sure what to show.
Thanks in advance!
Hi,
im a student currently working on a project at my university regarding rotary encoders and the different signal types they use.
After looking through a couple of signal types for my task i stumpled upon EtherCat and was wondering if there is any module capable of implementing a Ethercat signal into my NI PXI-1042.
Since i'm by far no specialist on this topic i thought i'll give this Forum a try.
Thank you guys very much in advance.
I have a PXI 1082 chassis with an 8880 controller, and a 6355 in expansion slot 5. The controller is synchronized via PTP to a master clock on the network, but when I collect samples through DAQmx all the timestamps are 23 seconds early, even though the system time (from get system time vi) is correct. This only happens when building and deploying as a startup program, the timestamps are correct when running from development mode.
There is a near-identical chassis running identical software, but the timestamps always match the system time. The only difference is that the other chassis also has an RTD module in slot 4. The sample clock source is set as "OnboardClock" when creating the DAQmx tasks.
I've been trying to troubleshoot this for a while but I'm quite stuck. I've tried using the Ni-Sync library but it throws an error stating it can't be used on remote systems. I've grabbing the reference clocks and other properties from tasks to compare between PXIs, but they're all identical.
