PXIe-5423 with NI-TClk

Mon, 22 Jan 2018 15:34:37 GMT2018-01-22T15:34:37Z

Does anyone have any experience with NI-TClk with a dual channel PXIe-5423.  I have two dual channel cards that I need to synchronize.  The synchronization on one dual channel module should be automatic, but I need to synchronize with the other module too.  Previously I was using NI-TClk with 3 PXIe-5422 arbs.  Eventually I would like to have four channels, which is part of the reason I upgraded.  My existing code for NI-TClk doesn't work, so I'm hoping someone has done this before with these new modules.

Setting up two HDD-8266 to aggregate streaming speed and storage space.

Sat, 20 Jan 2018 11:32:13 GMT2018-01-20T11:32:13Z

Hello, 

 

[Outstanding Question]

How can two sets of HDD-8266 be configured as one simple volume with doubled streaming performance and storage space, as guided in 

NI HDD-8266 Datasheet (http://www.ni.com/datasheet/pdf/en/ds-505) ? 

Or, does this article not say that one simple volume can be configured using multiple sets of HDD-8266?  Does it implicitly say same number of volumes (drives) should be created as the number of HDD-8266 in system, then, specify different drive letters for file saving, so that the total performance and space can be increased for the multiple numbers of HDD-8266 in system?

 

[Details]

I have two HDD-8266 and would like to set up one volume by using the two HDD-8266s, so that the volume can get doubled streaming performance and storage space. 

NI HDD-8266 Datasheet (http://www.ni.com/datasheet/pdf/en/ds-505) mentions that

 

"In a high-performance PXI Express chassis such as the NI PXIe-1085, you can increase the total stream to/from disk rates by using multiple HDD-8266 RAID enclosures. For example, in a single NI PXIe-1085 chassis with an NI PXIe-8135 embedded controller, you can interface two HDD-8266 enclosures to achieve a total stream to/from data rate of 7.2 GB/s."

 

This is exactly what I would like to achieve. 

 

I followed "Setting Up NI HDD-8266 RAID Configuration (http://www.ni.com/tutorial/53938/en/)".  Just with using only one set of HDD-8266, I successfully got 3.59GB/sec benchmark results with example programs of Adv. Async. TDMS Write/Read.  However, there is no guide of how to configure two sets of HDD-8266 as one volume in the document.  

 

Therefore, I visited MicroSemi support page to find further information, and found an article of "Is it possible to create an array that includes hard drives from multiple RAID controllers?" (http://ask.microsemi.com/app/answers/detail/a_id/2345/~/is-it-possible-to-create-an-array-that-includes-hard-drives-from-multiple-raid).  According to this article, it is not possible to configure two controllers to set up one volume.

Devices in PXI-1033 appear in MAX, chassis does not

Sat, 20 Jan 2018 01:24:26 GMT2018-01-20T01:24:26Z

I have a PXI-1033 with two PXI-2529s installed in it. Both PXI-2529 devices appear in MAX and pass self test, but the PXI-1033 does not. The PXI-2529 devices show "N/A" for PXI Chassis and PXI Slot, and are listed along side the DAQ device that is in a PCIe slot in the PC. Both PXI-2529s pass self-test and display their serial numbers in MAX. I can operate the switches on them using the soft front panel.

 

The drivers are older, but a proven (and version locked) configuration that has been deployed 5-6 times prior. The PXI-1033 is always on before the computer is turned on. I have tried changing the slot of the PCIe MXI card and resetting the MAX configuration data, but the problem remains.

 

I'm at a loss for what else to try. I could uninstall/reinstall PXI Platform Services, but I'm not sure what else to do. Any ideas?




Not able to detect second PXI chassis which is connected to first chassis using MXI cards

Fri, 19 Jan 2018 19:45:44 GMT2018-01-19T19:45:44Z

Hello,

I have 2 PXI chassis the first one is 1085 with 8115 controllers and 8364 MXI card, the second one is 1045 with PXI 8360 MXI card which is connected to 1085 chassis. I am trying to see both chassis and all cads in MAX, but I don't see 2nd chassis 1045 and related PXI cards I have in 1045 Chassis. 

 

I am using NI platform service 14.0 




PX1-1402 and PXI-8360/PCI8361

Fri, 19 Jan 2018 19:37:27 GMT2018-01-19T19:37:27Z

Hello,

Currently I have PXI-1402 with PXI-8330 interface to PC via PCI-8330. I just have new PC that has 3.3V PCI type so I can't use PCI-8330 with this PC.

Can I use PXI-8360 with PXI-1402? And connect it to PC via PCI-8361.
Are there any option that I still can use PXI-8330 with 3.3V PCI bus?

 

Thank you for your advice.




Connector Information for PXI-2535

Fri, 19 Jan 2018 09:11:53 GMT2018-01-19T09:11:53Z

Hi there,

 

We are using the PXI-2535 Switch Matrix in our chassis. We are using the SHC-68-68 cable for using the 2535. We are looking to develop a customised VHDCI-VHDCI cable.
The SHC68-68 drawing has a VHDCI connector - P/N is 690-68219SF00. 

 

Could someone share the datasheet of this? The manufacturer is listed as Bizconn. This looks to be a customized part.

 

Best Regards,
Sreekar

 




PXIe 6356 analog output issue

Tue, 16 Jan 2018 21:25:15 GMT2018-01-16T21:25:15Z

Hi there, I am trying to run a code where I need to provide voltage to analog output channels 0 and 1 on my SCB-68A connector block, which is connected to the Ni PXIe-6356 terminal block.  I am using a digital multimeter to test the voltage that is being provided to the analog output channels.  I need to supply 3.3 V to channel 1 and 6 V to channel 0.  For some reason, the voltage will not exceed 1.66V on channel 0. Can anyone assist me with this? I'm very new to electronics and I'm not sure if I'm missing some sort of connection or what.

 

Any assistance is greatly appreciated! Cheers.




NI PXI/PXIe/DAQmx compatibility with Keysight chassis/controller

Mon, 15 Jan 2018 23:23:14 GMT2018-01-15T23:23:14Z

Chassis: Keysight M9010A
Controller: Keysight M9036A, Windows 7, Keysight Connection Expert 2018, DAQmx version 15.5

Cards: NI PXI-6509(x2), NI PXIe-4303(x3), NI PXIe-6739(x2)

Host PC: standard Windows 7 PC, DAQmx version 15.5

Host PC and Controller connected over dedicated NICs

 

Desire is for software on host PC to access PXI(e) cards "through" controller.

 

Is this a supported configuration?

 

NI MAX can see PXI(e) cards from controller but not from host.  NI MAX doesn't appear to see chassis from either.




TestStand CVI Step dll not Loadable. Could not load DLL or external dll

Fri, 12 Jan 2018 20:59:49 GMT2018-01-12T20:59:49Z

We are using TestStand 2012 to call a cvi dll with the CVI adapter step.  We are getting an error that TestStand is unable to load the dll we are trying to call.  We verified the dll is good by loading it in LabVIEW with no discrepancies.  The error we are receiving is:

Message     : Module for Step 'drv_fcx_Init' not Loadable. Could not load DLL or external library 'C:\DMT\CSCI_8026707_FCNS-24\Source\FCNS Fiber Channel\drv_fcx\drv_fcx.dll'.


File        : C:\DMT\CSCI_8026707_FCNS-24\Sequences\FCNS_Fiber_Channel_Network_Analyzer.seq
Location    : Seq["Open"].Main["drv_fcx_Init"].TS.SData
Rule        : Code modules must be able to load
Description : TestStand must be able to load all code modules without error. TestStand reports errors at run time when it
cannot load a code module.  Correct this problem by editing the step in the sequence editor.

 

 

We were able to get TestStand to load and properly execute the test sequence by switching the step adapter settings by changing the settings:

 

From:

Execute Steps In-Process (CVI is NOT Required for This Mode) "this did not load the dll"

To:

Execute Steps in an External instance of CVI "this loads the dll and executes the sequence"

 

Any suggestions on how to fix this discrepancy would be greatly appreciated.




PXIe-1065 not detected by MAX.

Thu, 11 Jan 2018 02:35:09 GMT2018-01-11T02:35:09Z

Hello,

Need your brain.

I have a PXIe-1065 chassis connected to a PC via a MXI (PXIe-8360, PCIe-8362).  MAX sees the PCIe-8362 but doesn't detect the PXI chassis.  The PC Device manager also doesn't see the PXI chassis and has a PCI bridge error code 12 "This device cannot find enough resources that it can be used.  If you want to use this device, you have to disable another resource in the system".  The LINK led on the PXIe-8360 is also off.

This system has worked before.  I've tried the correct power sequence - power the PXI chassis before the PC - didn't work.  The MXI cable is good and installed correctly.  NI PXI Flatform service 14.0 is installed in the system.

What else should I look at?

Thank you.




Empty PXI 1045 power consumption

Wed, 10 Jan 2018 20:12:24 GMT2018-01-10T20:12:24Z

Hi, is there information available about the max. power consumption of the PXI-1045 chassis itself? It seems like it would be drawing some current with its fans at least. I didn't see any specs like this in the manual.

 

Thanks!

NI PXI-8196 Controller Upgrade

Tue, 26 Dec 2017 22:32:54 GMT2017-12-26T22:32:54Z

Hi everyone,

 

I have a chassis model PXI-1042Q with an embedded controller model PXI-8196.

The system's resources are in the image attached. 

 

I would like to know if there is anything that can be done to improve the system and make it faster (apart from buying a newer controller).The computer and any operation on Labview is really slow.

 

Thank you.

Hello everyone

My application requires generation of sinusoidal signals from 0Hz to 18Khz ( having voltage range 50 mVrms to 7 Vrms) . The required resolution & accuracy is 1Hz and 0.1Hz respectively. Will PXI 6723 card can satisfy this requirement?




SERDES CLIP in External clock data Acquisition in Flex RIO

Thu, 21 Dec 2017 06:45:26 GMT2017-12-21T06:45:26Z

Can anyone explain the detailed structure of an SERDES Connector CLIP

in LabVIEW programming Flex RIO.

 

Additionally,

  1. How do the acquisition bits get arranged, with respect to each Channel Data?!
  2. How does the samples to be read considered?!!!
  3. If I have 16 LVDS Channels, how can I acquire each channels data considering each Lane to reconstruct separately.

Note: 

I have seen examples and stuffs related to flex-rio programming but there's no particular explanation for this CLIP, Where things go in deep with high importance.

 

KT is worth it!! Cause you are storing things permanently in your Brain (image)

Error -89126: Trigger line requested could not be reserved because it is already in use.

Mon, 18 Dec 2017 14:30:32 GMT2017-12-18T14:30:32Z

I am trying to control the "PXI_Trig0" using the ctr0 of a DAQ card PXIe-6366.

 

The trigger will be connected to the input trigger of the scope PXIe-5122 and starting the output generation a FGEN PXI-5412.

 

The problem is that after several tries the system complains that the PXI_Trig0 is in use when I try to start the crt0 (Error -89126) when this happens the only solution is to turn off the rack and boot again, doing so it works for a while but after some time debugging things the error pops up again.

 

Is there any way of reseting all the triggers of the rack? 

Is there any way of visualize what triggers are reserved in each moment?

 

Thanks.
