Generation/Acquisition using multiple HSDIO PXI 6556 with bi-directional signals

Hi,
I would like to run vectors to test some ICs using multiple (three) PXI6556 cards. The vectors have multiple (>20) bi-directional signals.
Questions:
1. The NI Examples library shows multiple-device generation and acquisition VIs. However, it seems the examples are on single direction signals. Could you show me some example on how to configure bi-directional signals?
2. The pin mapping in the vectors are not in the same order as the HSDIO card pin mapping. Is there an easy way or any tool to help channel mapping? I have 10+ vectors with 90+ digital signals. Manually remapping them is quite tedious.
3. Since we have three PXI6556 cards in the tester, is the "Multi-Device dynamic generation and acquisition" example VI the one to follow? Just to double check if there is any better way to do the configuration.
Thank you for your help!
Jing

hello jcao,
I have adressed your questions individually below:
1. bi-directional examples can be found in two locations Hardware Input and Output >> Modular Instruments >> Demos >> Dynamic Acquisition and Generation Demo.vi and Hardware Input and Output >> Modular Instruments >> Dynamic Acquisition and Generation >> Stimulus and Response Load from HWS File.vi . Both of these examples utilize the bi-directional functionality of our HSDIO cards.
2. The easiest way to map the pins is to use the Digital Waveform Editor software. You can import a VCD (Value Change Dump) file and save it as a NI-HWS file to be imported and used in LabVIEW (the second example above will show you how to use the HWS file). A VCD file should allow you to specify a signal name and assign it to a particular line.
3. The "Multi-Device dynamic generation and acquisition" example VI is the best to follow for syncing across multiple HSDIO devices. The examples use TCLK which is the recomended syncing method. I have also provided a link explaining TClk a little more thoroughly.

other problem is that the channel DAQmx only works at real time mode not on stand alone vi using Labview 8.2 and Real time 8.2

How can I use the NI PXI-6508 with Lab View 7? what are the first steps to get started??How can I use the channels with lab view 7????

I have a 8 slot PXI system with 2 NI PXI 6508 and 1 DMM 4070 in it. I want to get started with programming the digital I/O cards (6508)! How can I use this cards with LabView 7?what is the best way to get started, or where can I get examples showing how to use the several channels?
Thanks!
Philipp

Philipp,
The best way to get started is to decide if you want to use traditional NI-DAQ or NI-DAQmx. Recently we released NI-DAQ 7.1 which provides NI-DAQmx support for the PXI-6508. In my opinion, NI-DAQmx is more efficient and much easier to use.
To get started with examples, simply launch LabVIEW and go to Help>>Find Examples. Then expand Hardware Input and Output>>DAQmx and select the appropriate digital group for your application. This should help get you started.
Please repost if you need addition assistance. Good luck with your application!

Issues using multiple load-config files with ant

Hello,
Not sure if this is the correct place...
I am creating an ant build script to compile our flex application. I am trying to use the default flex-config by doing <load-config filename="${flex.sdkPath}/frameworks/flex-config.xml"/> and project specific config file add the datavisualization module and any other libraries we might need in the future. I am trying to do this as I don't want to modify the flex-config.xml
The issue I keep running into is I get a compiler error saying "unable to locate specified base class 'spark.comonents.application..". if I place the custome load-config file above the adobe default flex-config it gives errors stating it the "SeriesSlide" type
<mxmlc file="${project.sourcePath}/FBApp.mxml"
         output="${project.output.binaryPath}/${project.output.fileName}.swf"
         locale="en_US"
         static-link-runtime-shared-libraries="false"
         static-rsls="false"
         use-network="true"
         accessible="false"
         debug="true">
         <load-config filename="${flex.sdkPath}/frameworks/flex-config.xml"/>
         <load-config filename="C:/Hudson/.hudson/jobs/FB 2.0 Flex/workspace/FBApp/FB-config.xml"/>
         <source-path path-element="${flex.sdkPath}/frameworks/libs"/>
         <source-path path-element="${project.sourcePath}"/>
         <library-path dir="${flex.path}/sdks/${flex.sdkVersion}/frameworks/locale/en_US"
            includes="*"/>
         <library-path dir="${project.libraryPath}"
            includes="*"/>
         <keep-as3-metadata name="Protected"/>
      </mxmlc>
the following is my FB-config.xml
<?xml version="1.0"?>
<flex-config>
   <runtime-shared-library-path>
<path-element>C:\Program Files\Adobe\Adobe Flash Builder 4 Plug-in\sdks\4.1.0\frameworks\libs/datavisualization.swc</path-element>

<policy-file-url>.</policy-file-url>
   </runtime-shared-library-path>
</flex-config>
It seems to be that the first "load-config" ant runs into is the only one that gets used. When looking around the internet I have multiple cases of where people say they have successfully used multiple load-config files.
This one in particular.
http://flashdevelop.org/community/viewtopic.php?f=13&t=5629&view=previous
If I had to guess on what was wrong I believe my FB-config.xml file is incorrect but I can't find an example of anyones custom configuration file.
Any guidance would be apprecaited.

I am embarrassed to say that your solution answered my question.
I was about 10 min away from rewriting my Ant script to just use the mxmlc.exe directly instead of the mxmlc ant tag. I kept running into the -flex-config+=YourConfig.xml for the command line option but never saw the xml variant.

Does Flex have any documenation that shows all the different tags that are available like the Ant documenation?

Measuring digital signals coming from the HSDIO (PXI-6542) with the DMM (PXI-4070)

Hello,
in attachment you can find the program I'm using for my measurement: I'm generating and acquiring digital signals with the PXI-6542 and at some trigger point of one of those digital signals I'd like to capture the measured values on a plot with the Digital MultiMeter (PXI-4070).
It does work if you configure the generation repeat mode as continuous, but if you do have a finite repetition (repeat count is 1) it doesn't react on the trigger, as if it can't find a trigger. On the other hand, if you have a finite repeat count of 30 or more it does react and triggers correctly again.
First I though it had something to do with autocalibration before the measurement takes place, but If you do a highlight execution (stepping through the program) it looks like it measures before the generation session is initialized.
Is there a way to measure correctly when the repeat count is only 1?
Thanks in advance,
Jürgen

Hey Jürgen. I apologize that you haven't gotten an answer yet to your post. I looked at your code and had some questions. What is the source of your trigger to your DMM? I see that you're exporting the data active event to PFI1, and your comments indicate that PFI1 and PFI2 are connected to give you a start trigger for your digital acquisition. Exporting the data active event with a finite or continuous pulse should only give you a single edge per run, though - you wouldn't get a pulse each time. Is your trigger coming from a data line? I didn't see any line in your included data that would indicate a single pulse.
The other thing that I noticed is that you've got no timing dependency between your HSDIO code and your DMM code - they're in parallel with each other. Thus you could get different results run-to-run, since it's not deterministic as to which parallel "thread" that LV will start on first. LV may switch back and forth several times, but let's say that LV reaches the HSDIO Start command before reaching the DMM Start command - in that case, the HSDIO device may finish it's entire operation before the DMM ever starts looking for a trigger, and thus never get the trigger at all. I'm not sure why this would explain why you're seeing the finite case work and the continuous case not, but I wanted to point it out because it could bite you down the road.
I hope some of this this helps get you going in the right direction. I'd also suggest posting HW-centric questions in the appropriate form. There are Digital forums and DMM forums that might help you reach people that will be more familiar with your particular hardware.

How to set up and use multiple Ext HD compatible with Windows w/o emulating

I am in deep doodle and confused, sit down and get a cup of coffee cuz is going to be loooooong.
I need some suggestions for my present situation. I have posted a similar question but I only got partial answer and I need to complete this task.
I migrated to my Mac from Windows, and I still have a Windows XP laptop. At first, I formatted my Ext HD as FAT 32 but I noticed that it was too slow. I was suggested to reformat the drives back to Journal. However, recently I had to replace my internal HD and backed up all my data to several Ext. HD. Oh brother what a mistake, while my Mac was at Apple I couldn't get access to my files using my Windows XP laptop because all drives were formatted as Journal (only for Mac).
At the moment, I have the following:
1- Seagate (350 GB orig)- complete back up images 110 GB avail
2- Maxtor ( 500 GB orig) - " " second copy 330 GB avail
3- Old int w/ casing(150 GB orig) 3rd copy 78 GB avail - is working but not sure if it will last, I had this DR for a long time. All 3 DRs formatted as Journal
4- Western Dig 1TB (new FW) 1TB avail
I realized that at the rate that I am shooting I would be running out of space on the current Drives. So I bought 1TB Ext HD FW, but I am in great need from others with more experience than me in setting up a strategy to back up and using my Ext HD. I only use the Int. HD DR 250 GB for Apps only, anything else I use exclusively my Ext HD.
So I would like to know which drive should I use as my primary one, and how I should set up the other subsequent drives as shown above. Do you think that I should reformat all the drives back to FAT 32, (what a task)? I'm also aware the 4 GB limitations. Or should I just format to FAT 32 the 1 TB, and can I partition the this drive and Format each partition with different format,ie. a couple NTFS and one FAT32.
Thanks in advance to all

You can also share a printer between the Mac/PC as well as files and mounted Volumes, see the Tiger articles here
http://www.ifelix.co.uk/tech/
You may want to use Bonjour for Windows on your PC
http://www.apple.com/macosx/features/bonjour/
Then there are VNC clients for Mac/PC that also allow you to actually control the other machine, if they aren't in the same room and you just need to check something quick that can be handy, it's kind of slow though for regular use.
The main benefit of partitioning is being able to have different versions of bootable OS on them. You can try out Leopard on a new partition, while keeping your Tiger partition intact, you can have a XP/Vista partition for parallels or BootCamp, etc... other than that drives are pretty much fast enough, having smaller partitions probably won't realize any significant speed ups over searching the whole large drive.

How do you use multiple apple id's with messages beta?

With the wife and myself each having our own apple Id's for imessage because of multiple iphones/ipads, how do we make messages beta on the mac work for us? I tried logging in as me when I installed it and it works just fine with me messaging her and her back to me but how do I log out from me and log in as her if she were the one sitting at the mac? I don't see anything that lets me do that.

hmm, that's a trick one! what I would do is go to Messages>preferences>accounts and then select imessages and then select account details and then sign out. Then your wife will need to sign in with her apple id.
hope this helps!!
let me know if that works because I've never actually tried it.
simply adding both of your accounts to be reached at will prove to be faulty because when you reply you can only reply with the one email address. And even if you switch caller id's it probably still won't work. So I think my method would be the easiest way to do that at this time.

Using Multiple Apple TV's with One Account

I am thinking of installing multiple Apple TV's in my home so we can rent/buy movies in different rooms. Is their any limitation of how many can be logged in at one time? Can I be downloading to multiple ATV's at the same time using the same account?

You can connect up to 5 tv's to your itunes library. Yes they can download content from the itunes store at the same time, playback the same or different content at the same time or a mixture of each. You may find though that this can put a strain on some networks and performance may vary.
I have 5, I can't say for sure I've ever had five playing movies together, certainly had 3 and probably 4 and for me they have worked well, albeit my network is a little more than what most people would want to set up.

Is it possible to use multiple log on IDs with OID?

First a little background on our environment. Our users currently have two seperate identities on our network. The ID used on our SUN JES (Mail and calendar) is made up of a combination of lastname and initials whereas our Oracle portal users are recognized using a numeric ID ie. 223044432. There is a one-to-one correspondence between the accounts, everyone with a mail account has a corresponding portal account. For example, I'm recognized as bouchers for mail but as 223044432 for my portal account.
We now have a requirement to unifying these identity. All new accounts will be using the numeric pattern on both JES and Portal. Management wants us to grandfather the old account names and for a period of time allow users to log-on to the portal using either the old user name or the new one. Is that possible?

Should be possible by setting up account synchronisation from Sun to OID, and changing the mapping rules. Basically, you end up with two accounts; either both in OID, or one in OID, the other one in Sun. The latter reuires a mechanism to authenticate against Sun when OID fails - don't know if that is possible (struggeling MS AD myself - that is doable)

Using multiple laptops and AirTunes with one static IP

I just moved into a place that requires a static IP they provided me. After much tinkering, I finally got the Airport Express to work so that I could get online using my Powerbook. However, whenever I'm on the internet (Airport set NOT to distribute IP addresses), I can't use AirTunes. The moment I change that (whether it's using Airport Admin Utility or changing Network Settings on the Powerbook) and I am able to get online again, AirTunes quits and iTunes can't seem to find the remote speakers again.
I can't even use these both at the same time, and I would eventually like to use AirTunes at the same time as the internet AND be able to connect wirelessly to the internet using my PC laptop. Before moving into the apartment with the static IP, this was possible.
I keep reading about port mapping - perhaps that is the answer? Problem is, I have no idea what that is. Can somebody please explain why this is happening and offer a solution?

a) WEP WPA password, ive never set one up for the airport, where do i find out what this password is for my PC?
You will set up wireless security (WEP or WPA) on the AirPort Express Base Station (AX)..using the AirPort Admin Utility, which is part of AirPort for Windows.
b) Everytime I run the Airport Express Assistant it gives me an error message saying "Windows is not the current network manager...please change Windows to the default", I dont know why I get this error and I assume windows is the one managing the networks I use.
Your PC has wireless capability...correct? The AirPort Setup Assistant requires a wireless connection to the AX.
c) I can connect to the airport through windows, but when in the Airport Management Utility it does not detect the Airport
Connect your PC directly, using an Ethernet cable, to the Ethernet port of the AX, and then run the AirPort Admin Utility to configure it.
d) After all this, will Windows and iTunes allow you to stream music thru the Airport Express, like it does on my mac with itunes???
Yes, you will be able to stream iTunes from your PC to the AX, either wired or wirelessly.

Is it possible to use multiple macs/iphones/ipads with single apple tv for an exhibition?

Hellow everyone,
Wondering if some genius out there can help me come up with a solution, or whether this is just too pie in the sky!!
So, I'm exhibiting at a huge conference at the end of the month and want the following set up:
MacBook Pro Retina showing a video loop through AirPlay Mirroring
MacBook Pro showing exmaples of my work in safari photoshop etc through AirPlay Mirroring
iPhone (4s with iOS7) to show examples of my work in safari through AirPlay Mirroring
iPad (iPad 2 with iOS7) to show examples of my work in safair through AirPlay Mirroring
So, basically I want the video loop to play constantly and act as a screensaver almost, then when the sitution dictates I can quickly switch what is being shown on the AppleTV to whichever device I am at.
As an example, the video loop is happily playing. Someone comes up to me and wants to talk about responsive web design. I whip out my iPad and load up an example site in safari. if I turn on my AirPlay Mirroring, great the AppleTV will update and show what is on my iPad. Great, but what about when I've finished with this person. I turn AirPlay Mirroring off on my iPad and the ApplTV goes back to the main menu because it has kicked out my MacBook Pro. Imagine this scenairo happening time and itme again.
The question is, is there anyway of making some kind of heirachy where my MacBook Pro with the video is the default source, then the Apple switches depending on what is selected, then reverts back to the MacBook Pro??
Or, is there a neat little app that I can run from another iphone (almost using is as a remote) to select which source the Apple TV shows and all the devices are constantly running AirDisplay?
Possibly asking a bit too much here, but it would be amazing if I could get some form of solution that allows me to use minimum wires and no fidly changing channels on the tv with a remote!!
Many thanks in advance!
David

Using multiple guides to help with layout

Hi,
I have seen in lots of Muse and InDesign training videos that the designers are using multi guides which run vertically. The guides are set with a wider gap, then a narrow gap, then a wider gap etc. I know this to aid layout and create a more uniform spacing.
Can anyone tell me the method used to create the guides and how the gaps (wide and narrow) are calculated.
Thanks,
Matt

In the new site dialog box on the upper right side. The wide ones are the columns and the narrow are the gutters. Hope this helps

Using multiple VZ Access devices with one PC

How do I set my laptop up so that sometimes I can use my RIM 9550 and other times use my UM150VW modem?
Thanks
Steff

I'm doing exactly what you want to do. I have a linksys WRT54GP2A-AT (wireless router with AT&T VOIP) downstairs and a WAP54G upstairs. I have the same SSID, same channel, and same security settings. My laptop will connect to the strongest signal. You can bring up the wireless client list on the WRT and see that the laptop is there or not depending on where in the house i am. I walked downstairs from upstairs and move from one wap to the other automatically. Pretty cool.

HT1495 how to use multiple apple id's with a single itunes account

I am looking to set up two iphones and a two ipads (one for me and one for my fiance) to a single itunes account to allow us to load music and apps from the same itunes account but be able to have seperate accounts for facetime on our phones and ipads. Any recommendations on the best way to do this?

You cannot do that. Each Apple ID needs to be tied to each separate account. Each of you must purchase your own copies of music and apps and sync to separate iTunes Libraries on the computer. The computer must have to user accounts set up - one for you and one for your fiance.
Sharing Stuff From Different iTunes Accounts (or Computers)
Here's how to do so using different computers:
Transfer what content you want to the separate iTunes library on each computer. To transfer content from your library to another library do the following. We'll assume this is between husband and wife separate accounts and different Apple IDs.
Launch iTunes under your wife's login;
Sign her out of iTunes, then you sign in;
Select iTunes -> Preferences -> Devices -> Disable auto-sync when an iPod/iPhone is connected;
Connect your phone, DO NOT SYNC;
Select Store -> Authorize this Computer (only have to do this once);
Select File -> Transfer Purchases (all of the purchased content on your phone will be transferred to your wife's library);
When complete eject your phone, sign out of iTunes, sign your wife back in.
You can now sync whatever content you want to your wife's phone. Just remember all updates to apps obtained using your account must be done while signed in using your account: sign wife out, you sign in, update apps, you sign out, sign wife in, sync her phone.
This way you can share content (permitted under the EUSLA) and still maintain your separate logins. Do the same on your computer if you want to share content from your wife's library.
Just load whatever content you want to share on each others phones, transfer the content, then delete it from the respective phone if you don't want to keep it there.
