PXIe-8135 Displayport & USB

Hi,
I hope to upgrade my current controller to PXIe-8135RT. My application requires me to have at least four display output (VGA, DVI or HDMI). So now, I have these questions:
1. Since the controller will run in RT, how do I make use of the two displayports on the controller? I don't need to display fancy graphic, just some custom black & white shapes. Can I use the tools in NI Vision, or is there a more suitable tool to do this?
2. The controller also have four USB ports as well as two super-speed USB ports. Besides for connecting USB thumbdrives, can I use the super-speed USB ports to connect to my USB-to-VGA video adapter?
3. Assuming that the answers to the above two questions are NO, will the circumstances change if I use NI HyperVisor (I've seen demos but haven't used one myself)? Perhaps, 3 cores and 3 GB of RAM for RT and 1 core and 1GB of RAM for Windows.
Please advice.

For #1 and #2, I am not aware of a way that you can use four monitors with distinct output on a dedicated PXI RT controller, and I don't think that USB-VGA adapters are supported.
For #3, RT Hypervisor might be a solution for your application, but there are some caveats. Different I/O resources (like the video output, the USB ports, or the PXIe slots) are dedicated to each of the two OSs, and video is typically routed to the Windows OS. However, the basis for determing what resources can go to which OS gets complicated, so I would encourage you to review some of the existing white papers on RT Hypervisor if you are still interested in this approach. See here, here, or here.
To give you an example, Hypervisor is intended for applications where you wish to do a portion of the I/O on each OS, and I think that at a minimum 25% of your PXIe slots must be assigned to the Windows OS. If all you need Windows for is to provide multi-monitor support, you might want to consider alternatives that keep the real-time processing and display on separate controllers.

Convert PXIe-8135 controller to dual-boot Windows 7 and LabVIEW RT

Hello. I have a PXIe-8135 controller that originally was just running Windows 7. We are trying to convert it to a dual boot system to also run LabView Real Time. (There is host computer that will run LabVIEW 2014 with the RT module, and the controller will become a target).
I have created a FAT32 partition on the hard drive of the controller. Now, I’m trying to install the real-time OS with a USB flash drive made using the MAX utility, but I cannot boot using the USB drive for some reason. I keep getting the message “waiting for USB device to initialize”.
In BIOS, legacy USB support is [ENABLED] and boot configuration is set to [Windows/other OS]. I’ve tried removing the drive, waiting, and reinserting. I’ve tried two different USB drives (both 8 GB, different brands).
I’m not sure what to do next. Apart from the USB boot issue, is converting the PXIe-8135 even possible? I read about SATA/PATA hard drive issues with older controllers, but I don't know about this one.
Thanks, in advance, for your help!

Go to Solution.

Per Siana's licensing comment, more information on purchasing a deployment license if you do not have one for this target can be found here.
The RT Utility USB key is used to set up non-NI hardware with LabVIEW Real-Time, but you should not need it in this situation to convert to dual-boot (*). Try this:
1. Since you already have a FAT32 partion created, go into BIOS setup and change to booting 'LabVIEW RT'.
2. The system will attempt to boot LabVIEW RT, see that the partition is empty, and switch over into LabVIEW RT Safe Mode. (this safemode is built into the firmware, which is why you don't really need the USB key).
3. The system should come up correctly and be detectable from MAX, and you can proceed with installing software.
4. To switch back to Windows, go back to BIOS setup and choose 'Windows/Other OS'
(*) One area where the USB key is helpful on a dual boot system is with formatting the disk. If you want to convert from FAT32 to Reliance on the partition designated for LabVIEW RT, the USB key lets you attempt to format a single parition and leave the rest of the disk untouched. If you format from MAX, the standard behavior is to format only one RT partition if found, but if not found, it will format the entire disk. Formatting from MAX on a dual boot system is consequently riskier and you could lose your Windows partition.

Imaq RT Video Out using PXIe-8135

Hi all,
I am planning to get a PXIe-8135 RT controller and have a requirement to display the image out via the DP port. My questions are:
1. The IMAQ RT Video Out does support PXIe-8135, doesn't it? My concern is because the controller doesn't have VGA or DVI but DP (DisplayPort). Will it work the same?
2. PXIe-8135 has two DP's. Assuming the answer to Q1 above is positive, can I display two different images to both of the DP's?
Please advice.

Hi Shazlan,
1- Yes PXIe-8135 RT controller do support IMAQRT Video Out function.
2- I'm not sure if it's possible since the 2nd DP is just an extended display of the 1st DP

Kanex MIni DisplayPort+USB Audio to HDMI Adapter --NO SOUND

Hi,
I just purchased a Kanex Mini DisplayPort+USB Audio to HDMI Adapter for my new Samsung flat screen so I could watch netflix movies. The guy at Tekserve (NYC based authorized dealer) said it's really cool b/c it's audio and video all in one. Two cables are attached to a small box on one side and on the other side of the box is for the HDMI cable which goes to the TV (most of you prpbably already know this) .
The two attached cables fit into the the USB (audio) + mini display port. The video works great, but no sound. I called Apple for tech support and we tried a few things like changing the sound output to USB, but no luck.
I can call Tekserve on Monday, but would love to figure this out before then for the week-end.
Thanks everyone for your help.
Mary

There are actually 2 different Mini Display port to HDMI adapters from Kanex. One supports 2 channel audio through the USB audio out cable, which is the one you have Mary. The other one with the extra audio plug cable supports 5.1 digital audio.

http://kanexlive.com/products/item.aspx?id=3495
I don't have either of these adapters but I would think that you "should" be able to go into your System Preferences under Sound. If the USB plug from the adapter is plugged into your MacBook, then it should show up in the output window in the Sound preferences which you would then choose instead of outputting the sound to the built-in MacBook speakers.
At the bottom of the product description page of the adapter that you have (the USB 2.0 version), it says this:
+Sound Output setting on Macs must be changed to "USB Sound Device/USB Type" to have the adapter operating correctly.+*
Let us know if you get it working properly. I'm considering getting one also.
Sorry.... I just re-read your initial post and it sounds like you already DID try switching the sound output to USB with no luck. The only other thing I can think of is the adapter might be bad and maybe exchange it for another one from where you purchased it. Or you could maybe exchange it for the 5.1 digital audio out version. Although it sounds like your sound is going directly into the tv via HDMI and not a surround sound receiver.
Kanex does have tech support and contact links on their web page. Maybe you should email them directly about your problem. Unfortunately I'm sure you'll have to wait til sometime during the work week to get a reply back.

PXIe-8135 Watchdog

Hello,
I'm putting together a testing rack that will be used to control a system during testing. The heart of the rack is a PXIe-1065 chassis with PXIe-8135 controller. The rack will be controled remotely through Remote Desktoping into the controller (this is necessary because the test involves pressurizing sections of the system high enough that it is dangerous for any personnel to be in the room while the system is pressed up). The test control software will not be LabView, but our own software that interfaces with the modules in the PXIe chassis.
I would like a watchdog in the rack to monitor the PXIe controller and restart it without any need for someone to go in the room in the event that the system freezes up or otherwise becomes unresponsive. I'm aware of some possible solutions for a remote restart (Intel AMT, remote-controlled power strip), but response times on those could be too slow depending on the state of the rack when it goes unresponsive. I'm fairly certain I'm not the first to do this, so I was hoping to get some info and ideas.
From browsing the manual, it looks like there are watchdogs internal to the controller, but these are not accessible unless your using LabView RT. Anybody know if that is correct?
Are there any other options for a watchdog internal to the PXIe controller?
If not, any recommendations for getting an external watchdog? I assume it would have to connect up to the inhibit connector on the back and connect the proper pins in case it detects a problem.
Thanks!

Hi pghohnst,
It is possible to control the power of a PXI Chassis with the DB 9 connector that is found on the back of the chassis. More information can be found in the KnowledgeBase below.

Problems directly connecting Windows 7 HP EliteBook to NI PXIe-8135 Embedded Controller

For some reason my computer cannot connect to the NI PXIe-8135 Embedded Controller in my PXIe-1082 chassis. My computer recognizes that there is something there, but it cannot communicate with it (no packets recieved back, but packets sent). I've already checked my firewall settings, network settings, and anything else I could think of that might be preventing me from connecting to it but I have not found a single thing that tells me why I cannot connect.
Any ideas on troubleshooting this problem, or if someone has run into the same problem please let me know - any help is greatly appreciated!
-flynneva

Hi flynneva,
Are you using an ethernet cable to connect to your PC? It sounds like you just want to add this chassis to your network just like any other computer (with the embedded controller is a computer). Here is a link to Microsoft's page on this type of connection in case you haven't tried these options:
http://support.microsoft.com/kb/305621
Also, is this embedded computer running Windows or is it a RT controller? What does your computer do to recognize the connection and what are you using to read the data? Can you ping the IP address of the controller and receive a response?
Thanks!

How do I calculate the max latency of a PXI 8135 (controller) to PXI 6528 (DIO) output?

We are using a PXIe- 8135 Controller and a PXI-6528 DIO module in a PXIe-1082 chassis. We are sending DIO input and output commands using Powershell in Windows 7 on the controller. Due to tight requirements I need to know what is the max latency from when the Powershell command is issued to when the read input or write output command will take place in the DIO I/Os.
If this should be in a different Community Board Location please let me know.
Thanks for the help in advance,
Dan_F

Hello dan_f,
As the latency of Powershell and Windows are not tested, it is hard to determine the latency of your setup. The latency from the PXIe-8135 to the PXI-6528 should be in the realm of nanoseconds. The PXI-6528 does have a couple of latency numbers that can be found within the user manual on Page 24, and they are as follows:
Minimum pulse-width for change detection - 150 µs
Propagation delay - 65 µs, typical
You may be able to do some testing to ballpark the latency of the controller OS/software side of the input/output commands, but depending on how critical this latency is to your measurements, you may want to look into using a real-time OS instead.

Can't find PXIe 8135 as a option in MAX

Hi
I am trying to setup a project with the PXIe 8135 controller and the PXIe 1085 chassis but can't find it in MAX. I am currently downloading the latest DAQmx drivers 9.6.1, so hopefully that helps. I am trying to run the setup the project with simulated hardware until we get the PXI that's on order.

NO Luck... Look DAQmx 9.6 is not installed yet and it look like I dont have support for the PXIe8135 yet I am running LABVIEW 2011

PXIe 8135 GPIB

I am trying to connect an ENA series Agilent network analyser to my PXIe 8135 controller, the connectors however are different sizes, is this some sort of mini GPIB port or a national instruments specific port?
Do you know where I can get the correct cable or find the right information about this communication.
Regards

Yes I did but only to check if it was a standard GPIB port, not through the accesories.
So the cable to purchase is the 'X13 GPIB Cable, MicroD25 to Shielded cable/Standard connector, 2M' for £98

I need help changing a VI from NI PXI-1042Q to USB-6210

Hello all. This is my first post, and I apologize ahead of time if it's in the wrong place or is inappropriate... I was instructed to come here for help.
I am working on changing a VI that is functioning perfectly with an NI PXI-1042Q over to a much smaller unit, the USB-6210. Supposedly the USB-6210 can handle the same inputs/outputs that I need (one analog input read at 30 kHz, 2 digital outputs written at 10 kHz), however I am having a bit of trouble getting it to work properly. The outputs seem to go where they are supposed to, but the new system is orders of magnitude slower than the original, and for the system I am using this is unacceptable.
I'm sure I'm doing something wrong, but I'm about as new to LabView as you can get so I have no idea where to start. Any help would be appreciated.
Additional info you might need:
LabVIEW 2010
The VI is attached.

In this topic we will discuss some of the common problems that have been observed using USB devices with LabVIEW on Windows operating systems. Many of these points are also applicable to other environments but the examples will be use the Windows 7 OS.
FAQ 1 : My USB device stops working unexpectedly.
The first thing to look at is the OS power saving options. There is a global trend towards developing "Green" electronics and energy star ratings are getting fairly common. "If its not being used shut it off" is nothing new. Cavemen learned how to bank a fire to preserve energy that would otherwise be wasted. Likewise, the Windows OS has a power saving feature to shut down power to the USB hubs when no user activity is present. In Automated systems this feature can cause problems since removing USB hub power will shut down the USB device. Solution: Use the device manager to change the USB hub Power Options.
FAQ2: I set the power options and my device connection is still unreliable: Remember, those computer USB ports are often the cheapest that can be mounted on the chassis and share the PC system power supply to supply USB Power. Most uses of USB are temporary connections like a thumb drive or a camera. These connections do not require high reliability since the user is right there interacting with it. Power surges and fault tolerance at worst cause the operator to retry the data transfer. Automated systems require a bit more robustness. Solutions:
1) ALWAYS use an external self powered hub. Perform your engineering due diligence and inspect the devices specifications too- If you can't find them for that device that should clue you to seek an product from a vendor that WILL publish their specs.
2) High noise environments require the use of ferrites on the USB cable- and don't buy the cheapest cable either! The cheap ones are poorly shielded.
3) PROTECT the HUB connections- If you have a USB2.0 device and Joe User plugs in a 1.0 device in a open slot managed by the same hub- Bingo every port on the hub may back convert to USB1.0. WORSE there are a lot of damaged or marginally engineered USB devices out there. Joe User's device may cause power fluctuations when it is inserted or removed from the hub just don't let it happen!
FAQ3: I am testing USB devices and the OS can't find them anymore.
This is a Plug-n-Play feature that deserves some exposure. When you connect a P-n-P device the OS remembers its serial number in a HKEY (Hive-Key) registry entry. This is helpful when (for example) you want a specific instrument, Say an NI-USB-6008, to show up as a DAQmx Device with VISA Alias "MyDAQ1" every time it is plugged it. On the other hand, If you want to test a line of USB-Serial converters this can be problematic since the P-n-P driver will mount the first serial number as "COM3" and the next as "COM4" add infinitum until the enumerator controller in the registry and VISA recognized aliases get used up. Solution: Use the Windows registry API and the Hardware Configuration API in LabVIEW to clear unused VISA Aliases and HKEY entries. Speak with your staff IT professional about HKEY structure and possible side effects before developing a plan to edit registry entries.

Simultaneously triggered acquisition: Multiple PXIe-7962R + NI-5734 cards, across multiple PXIe-1085 chasses

Hi all,
I need to do high-frequency, high-channel-count acquisition.
Specs
Signals: 10 MHz, 60 channels
Controller: PXIe-8135 (Windows 7)
Chasses: PXIe-1085 (2x)
Input cards: PXIe-7962R FlexRIO base with NI-5734 digitizer (15x)
Description
Each FlexRIO card will store data in circular buffers, and continuously monitor the voltage levels. When any one channel exceeds the user-defined threshold, all 60 channels need to be triggered simultaneously to pass waveform data (200 μs pre-trigger, 300 μs post-trigger) to the host OS for logging.
In other words, every FlexRIO card needs the ability to fire the trigger, which is then received by all 15 FlexRIO cards (the card that fires the trigger also needs to receive the trigger).
Question
Can I achieve this with only a single PFI line? Or do I need some other technique?
I've found some examples, but they only show single-source and single-card triggering, e.g. https://decibel.ni.com/content/docs/DOC-30182 uses one analogue input to trigger the acquisition of 2 channels on the same card.
Any advice would be much appreciated. Thanks!

Assuming you are using LV 2013 or 2014 you should download version 1.3.4 of the FlexRIO Instrument Development Library (FIDL). This will install 5734 Acquisition Engine examples which use the MultiRecord Library to stream data to the DRAM in a circular buffer, allowing you to recover pre-trigger samples. The example also demonstrate how to implement the Syncrhonization Library that synchronizes triggered acquisition to within a single sample period across multiple devices.
Getting the example to work across two chassis' may be difficult, but I believe it is possible. Though to do so you will need a timing and sync module in each chassis to distribute the triggers and reference clock that the sycnrhonization library requires.

PXI first use, unable to configure/boot safe mode or RT

Hi all,
I am new to PXI controllers, i am having a few issues with a PXI controller in my university which i intend to use for my fyp project.
So we are using a PXI 1042Q chassis with a PXI 8106 embedded controller.
We started this controller for the first time and updated windows xp, we also removed labview 8.6 that came with it and installed labview 2010 with all the available drivers, softwares and liscenses..
When we start windows XP on the PXI system we can see the PXI chassis and controller identified in MAX but labview cannot find them when creating a project.. My first question concerns the reason why labview cannot identify PXI targets in a project?, could it be a missing liscence (for instance RT liscence for PXI)? or an improperly installed driver? How to check if RT liscence is missing or needed?
Due to the first problem, we tried to control the PXI remotelty from another desktop host PC where we found more problems.
1/ Can we make a connection in order to download a project from the host PC to the PXI via ETHERNET (without MXI cards) ?
2/ We tried to make the connection using ethernet but we couldnt configure the IP; when we switch to safe mode to configure, the pxi gives the following texts on screen " system error kernel 446610 LFS error not a dos disk pc-dskinit " and the system remains unconfigured with the 0.0.0.0 IP due to the failure to boot, MAX on the host PC sees the PXI as a 0.0.0.0 and changing the IP is not possible also.
To cure this issue and help the system boot, we created a desktop PC utility USB Drive in MAX (on the host PC), configured the boot devices priority on PXI and booted the PXI from the USB drive. we entered safe mode and the pxi took an IP automatically and then it displayed that the software is not present... The problem is that when we tried to install the software on the pxi using MAX on the host PC (which now sees the PXI) we got disconnected..
Note that firewall is off, the host pc has an ip in range with the one generated by the pxi, on the same subnet and has windows 7..So why are we loosing the connection in MAX after 30 seconds,, when we try to install the software on the pxi?
thank you in advance for your help.
Elias Saleh.

Dear Elias579,
Welcome you to the NI Forums!
There are basically three ways a PXI system can by characterised by the OS:
Real-Time OS running on the PXI makes it an RT Target, which then can be reached from the network by a host PC for example
"regular" Windows running on the PXI makes it a simple industrial PC, which has no real-time qualities. In this case you cannot add the controller to your project, since you are actually on the target, and whatever VIs you crate are actually on the platform already!
Hybrid systems (not all controllers are compatible with this) can run in such a way that one core runs regular Windows and an other runs an RT OS, which can communicate with each other.
Your problem is either
1.) You installed a simple windows, in which case you wont add any targets to your project since you are running every VIs on the target. The chassis works exactly like a PCIe bus slot extender, so the cards inside are the ones that matter. For example if you have a programmable FPGA PXI card, and you have LABVIEW REAL-TIME and NI-RIO driver installed, you will be able to add the card within the chassis to your project.
2.) You are just missing a driver. Since you do not have an RT OS on the PXI, you might need a suitable DAQmx for you cards.
Please to help me have more vision of your problem try to describe what cards are you using and what is actually you would like to do.
For debugging you issue, these documents might help:

https://decibel.ni.com/content/docs/DOC-16189
**EDIT:
one more thing, if you are using a regular Windows PXI, you should not seek to connect to it as an RT Target. You might try to use Remote Desktop from an another PC though.
Looking forwards to help you solve your issue,

Multiple USB Audio Outputs?

Is it possible to set up the mac mini to have multiple USB audio out puts? I'm wanting to use a mini displayport + usb audio > hdmi cable to a plasma for computer use. But is I want to listen to just plain music use USB audio to a DAC into a 2 channel system. So for this system I would need to use 2 USB outputs for music.
Thanks

Sure,
You can output sound through more than one little external USB sound card, but probably not to more than one at a time. You'll have to select the Output in the Sound Preferences each time to switch them, too.
But don't overlook the Mini's internal sound output as one of your 2-channel or 5.1 audio outputs. The 2009 Mini has better audio output than the PPC Mini, that I also had and used an external USB sound card with (M-Audio Transit). Of course, now there are cheap little external USB sound cards that look like a little thumb drive for an added 2-channel audio output. So, I'd use the Mini's internal output and an Optical cable for 5.1 sound out, if I were going to use one of those cheap little sound cards. But you can go the other way, too, if you want, with a better USB dongle (like the M-Audio Transit) for your 5.1 sound.
Please let us all hear how it goes and what path works for your application.
Peace to you,
C. Livingstone
