External control of 1062q Chassis
We currently have a PXIe-1062q chassis with a PXIe8133 embedded controller. We wanted to instead use external control via a PXI-PCI connection using a PXI-PCIe-8361 kit. I was told this would be viable by one of the Sales Engineers.
However, the problem seems to be that the PXI-8360 card itself fits only in the peripheral slots, and if nothing is connected to the "System Controller Slot" the chassis will not switch on. The only card we have besides the embedded controller that fits in the Controller slot is a PXI-6535 Digital I/O card.
How would it be possible to use the chassis for our I/O cards, but control them using the PXI-PCIe connection to an external computer and NOT the embedded controller?
Kind Regards
Daryl

PXI-6713 not detected in MAX
Hi,
I am using PXIe-1082 chassis with Expresscard-8360. I have four PXI-6713 Modules in the chassis. I do not see the chassis or the modules under the "Devices and Interfaces" in MAX. Expresscard-8360 is recognized and displayed.
I am turning on the computer after the chassis has been powered on with the Expresscard inserted into the computer.
I have NI-DAQmx version 9.5.1 and MAX version 5.6.0
Please help!

PXI-5610 fails. Really need help, I live in Vnzla and have no money to send it for repair.
Hi everyone, I have the same problem as discussed in this post 7 years ago:
The thing is, I'm student doing my final degree project with PXI 1042Q with the modules 5610, 5441, 5600, 5142 and controller 8106. As for the bad situation in Vnzla, there is no money to send PXI 5610 for repair 
, so I would please beg anyone for any help or procedure that could work this out.
Im getting this error in Labview from PXI 5610 at Initiate RFSG session.
DAQmx Error -200617 occurred:
Measurements: Output generation was aborted by the reverse power protection circuitry of the device. Either the output signal exceeded the output power limit, or power was being driven back into the output of the device by an external source. Correct the problem, then generate the signal again.
In MAX the self-test also fails which fails with error -200020.
Project involves transmission and reception using RFSG and RFSA. This was working perfectly days ago, suddenly today, it doesnt.

NI-VISA Driver Wizard, Interrupt detection, advanced options
Hello,
I have a fairly complicated interrupt controller to support that can throw 16 different interrupts, mapped to the lower 16 bits of an Interrupt Status Register and an Interrupt Enable Register. To detect if an interrupt is coming from the card, I have to do the following:
bool isMine = ( *(BAR1+INT_STATUS) & *(BAR1+INT_ENABLE) ) != 0; // casts omitted for clarity
The interrupt is the card's if any of the 16 interrupts is both fired and enabled.
The only way I found which replicates the required functionality within the constraints of the .inf driver wizard is to check bit by bit:
InterruptDetect0 = "C32 BAR1 0x00000040 0x00000001 0x00000001;C32 BAR1 0x00000050 0x00000001 0x00000001;"
InterruptDetect1 = "C32 BAR1 0x00000040 0x00000002 0x00000002;C32 BAR1 0x00000050 0x00000002 0x00000002;"
...
InterruptDetect15 = "C32 BAR1 0x00000040 0x00008000 0x00008000;C32 BAR1 0x00000050 0x00008000 0x00008000;"
Unfortunately that's 32 register reads where 2 would suffice. Is there some advanced vocabulary that can express the logical formula above more efficiently? Have I overlooked something?
regards,
Edgar

HS-DIO tutorials / guides / examples? PXIe-6544
Dear all,
Is there a repository for HS-DIO VI examples available? Are there tutorials? I am using a PXIe-6544 HS-RIO and would like to use static and dynamic signal generation. So far I got some basic functionality but often I am stuck. For the RIO or DAQ system there seems to be a lot more resources available. Also I could not find examples installed with the HS-DIO drivers on the local machine. What is a good starting point? Any help is appreciated. Thanks!

Can PXI-5441 AWG Output connect to Antenna?
Hello everyone,
I was working with PXI 1042Q Chassis with the modules PXI 5441 AWG connected to Upconverter PXI-5610 to transmit a wireless signal and receive it with Downconverter PXI-5600 connceted with the OSP PXI-5142. Tools used: RFSG and RFSA.
Sadly, the upconverter 5610 is damaged. I was wondering if instead of using the Upconverter I can just use AWG and connect output channel 0 to antenna (it was prevously connected to the Input of Upconverter) , which obviously means signal frequency will be much lower but the IF frecuency still works for me. What consecuences would I have with this change of configuration? I can use FGEN in the transmission and RFSA in reception right?
Thank you!!

OFDM Transmitter using RFSG
Hello all, I am a newbie in LabVIEW and I am trying to transmit this OFDM vi I got from document by ErikL (https://decibel.ni.com/content/docs/DOC-34781). But I got some error while trying to connect this vi to RFSG transmitter block (at the wire error out after rfsg Resample and Write block). The IQ rate set by default 5M with 1250 input bits. This is the error explanation:
Error 1 occurred at rfsg_Determine Parameters for Resampling (Validate Inputs).vi
Possible reason(s):
The Waveform Sample Rate must be greater than 1.
I construct it using Labview 2015 and PXIe 5646R.
Can anyone please help me with this problem? Any sample or answer would be very helpful.

What is the driver used for the PCI8360.
Hi,
Need your help
We have installed the PCI 8360 in the host PC and installed the latest version of the NI PXI platform services but it still see the device as an unknown device. Ius the NI PXI Platform services the source of the driver for the PCI 8360 ?Is this unknown device condition expected when we dont have the PCI8360 connected yet at the PXI8360 on the PXI system ?
Hoping for any response out there.
Thanks in advance.

Performance verification of PXI-4130 using Calibration executive 3.6
Hi,
I'm running a performance verification of NI PXI-4130 but the program always stop and hang on the part of "Current Prog Accuracy" tests @ 83%. Part 6 during direct connection of PXI-4130 CH1 and DMM current mode. (Error: auxiliary power was disconnected) Is there any power requirement on the AUX input? Any fix value?
Thanks!

What is the difference between compactPCI and PXI?
I know that PXI utilizes the PCI bus alongwith the rugged eurocards defined in the compactPCI standards.
However, I was looking through some images of compactPCI systems and they look similar to the PXI standard.
My question over here may seem very noob but I was not able to find much information on the web when I search for compactPCI vs PXI.
There has to be some modifications over compactPCI which led to the PXI architecture. I also like to know how does compactPCI work, like apart from the chassis, what acted like a controller? Were compactPCI controllers(similar to PXI controllers) available? It will be great if someone can share a pic of a compactPCI system, I mean complete chassis, controller and cards? I browsed through some web links such as
which looked quite similar to a PXI system and I am not able to figure out the difference between the two.
Is it that the chassis backplane in a PXI system is a compactPCI and the other features like cooling, power, drivers and software architecture are different?
Or are the clocks, triggers, star triggers properties of PXI and not of compact PCI. I know PXI (because it is implemented on cPCI) is backwards compatible to cPCI, which means all features of cPCI should be there on PXI. I want to know what features are additional in PXI over cPCI.
Any leads or relevant links to see will be appreciated.
Thanks !

Why does a motherboard not have as many slots as a PXI chassis?
What restricts a motherboard to have a large number of PCI slots? Is it the space, cooling, etc or does it have to do with the IEC connectors on the Eurocards of PXI?
Why should I go for a PXI chassis instead of a PCI expansion chassis? In case a higher bandwidth is a restriction, we can go for a x16 PCIe instead? Is the synchronization better in PXIe when compared to a PCIe?
Thanks !

UART communication
I have a PXI test system that I am using to test some custom hardware. A few of the tests require UART data to be sent and received. I have a UART to USB device I can use, but I would rather not depend on hardware outside of the PXI chassis if I can. I have some spare channels on a 6535 that I tried to use to get UART working. Unfortunately, I can't reliably receive long sequences of bytes (I can send them with no problems). I still have budget left to buy additional cards if I need to, but I'm not sure that any of them will allow for reliable UART communication. The big problem I had with the 6535s is that I can't always rearm the task fast enough for each byte, and software timing is too unreliable. I'm pretty sure that I'm going to have the same problem with any other card I pick also.
Is there some way to reliably get UART communication to work using just PXI hardware, or do I have to use some additional hardware (like a UART to USB converter)?

How to Convert A bit decimal number to a parallel output of binary form and need to generate it using scb 68
I have acually taken a numeric control and converted it into a boolean array and then using a for loop and shift registers i have converted the serial corresponding boolean array to parallel form 8 bit or 16 bit. Now when i check the output using a waveform graph i am having a parallel output,
for ex. if my input is 65535 which is the max. value my output is 1111....1111(16 1s). Now i convert this array to waveform using boolean to waveform conver.
and write it to my scb 68 daq. There is no error bt m not getting desired waveform on d scope. What can be the possible reasons and solution???

Are PXI-4461 and PXIe-4461 Cards Interchangeable?
I have a need to send some PXI-4461 and PXIe-4461 DSA cards in for calibration. Are these two cards interchangeable? Can I use a PXI-4461 as a temporary replacement/backup for a PXIe-4461 that I send in for calibration? Can I expect the same measurements and performance between the two cards?
I have found this article which states that a compatibility difference is the PXI Star Trigger pin was removed in PXIe (which I don't use). However, when I used a PXI-4461 to replace a PXIe-4461 in a test setup I noticed some pretty significant differences in audio measurements on the test system. I just wondered if this was typical and expected behavior or just an isolated case. http://digital.ni.com/public.nsf/allkb/5FF50CA761D6C59E86257C740067641B

PXIe devices fail self test on one pc, work fine on another
Hi everyone,
I have a NI PXIe-1078 rack connected to my PC. I have 7 slots populated and 5 of the devices work well but the other two fail the self test. Failing devices are CAN module and a DMM. I can see all the devices in NI-MAX.
I know the slots are working fine and PXIe rack itself is fine because when I connect to another PC, everything works okay.
Could this be related to motherboards or the BIOS version of the PC? Or could this be some setting of the PCI bus that limits the number of devices?
PC where rack works: Motherbaord - Supermicro X10SLA-F, BIOS - 2.2
PC where rack doesn't work: Motherbaord - ASUS H170-PRO, BIOS - 0314
Any help is appreciated,

Getting PXI chassis information through .NET?
Is there a way to pull the PXI chassis information through a .NET API? I have a PXIe-1085 attached to my PC through a PXIe-8381, and I'ld like to be able to pull information like firmware version, serial number, power voltages, temperatures, etc, from my .NET application.
I did find the MoldularInstrumentsSystem class in the NationalInstruments.SystemServices.DeviceServices namesapce, but that appears to only have information on the individual PXI cards, not the PXI chassis as a whole.

power inhibit switch NI PXIe-1071 2 positions
Hi,
I plugged the AC wire and turn on the power inhibit switch but it doesn't work. I would like to know if there are 2 positions for this switch because i think this switch is broken.
i also tried to turn the SW1 switch. http://www.ni.com/pdf/manuals/373011d.pdf (page 30) but always the same problem.
I would like to find the problem of this box.
Thank you.
