I can't measure many signals at the same time using the DAQCard-AI-16XE-50.

I'm using a Compaq Presario 1655 laptop with a DAQCard-AI-16XE-50 on the PCMCIA slot, and LabVIEW 6i and MAX 2.0.
I have a SCXI-1001 Chassis with SCXI-1122 and its terminal block SCXI-1322 installed (I have others too).
I'm trying to measure some signals at the same time, for instance, measuring 2 load cells signals, and a frequency of an indutive sensor (using the analog way with the "Extract Single Tone Information.vi").
I realized that I can't measure at the same time my signals, neither the load cells - a 10608 error occurrs "NI-DAQ LV: No transfer in progress for the specified resource".
What's the problem?
Some DAQCard limitation? Configuration?
Thanks!

Hello;
By your description I'm assuming you are trying to read those analog inputs in parallel. The SCXI-1122 doesn't have that feature. All the analog inputs will be multiplexed to one single Analog Input channel on your DAQ board. If you need to make measurements in parallel, you need to use one of the SCXI modules that allows that operation. For more information on what modules support that operation, you can always refer to our home page at www.ni.com.
Hope this helps.

I want to Connect my Mac Mini as a Slave to a Mac pro Server while at the same time using the Mac mini's thunderbolt ports peripherals ( ie monitor, Sound Card, Hard drives) Creating a poor man's new mac Pro. Can this be Done?

I want to Connect my Mac Mini as a Slave to a Mac pro Server while at the same time using the Mac mini's thunderbolt ports peripherals ( ie monitor, Sound Card, Hard drives) Creating a poor man's new mac Pro. Can this be Done?

Well, I really would love the new unreleased mac pro however , I'm not sure of the expected cost , Everyone speculates from $3,000 to $8,000, in which I may have to wait a while to purchase.
To the point .... I want fully functional thunderbolt ports to be on the current mac pro's .... wonder if anyone had workarounds yet?... or could I chain the the current mac pro to a mac mini to make that happen?

How do I read and write at the same time using the NI-CAN channel API?

Here's the situation. I have one CAN bus, and I need to read and write channel data (using the channel API) at the same time both at an interval of 20 ms. It's easy to do one or the other using the channel API, but you can't setup a channel task to do both. It's either input or output, not both. Is this even possible?

Hi,
yes , this is possible. But you have to create two tasks, one for input and one for output. see the attached example for LabVIEW.
If you download and install NI-CAN 2.4 you will get this example and one for C and VB as well.

How can i connect to a LAN and external display at the same time using the mini-displayport?

Hi all,
At work i'm connected to the Lan via an adapter and the mini displayport. I want to use my external display at the same time, which use the same mini displayport. Are there any splitters available to use both at the same time? Are there any other alternatives?
Thanks,
Dennis

There are USB to ethernet dongles:

Recording vocals and guitar at the same time, using the Alesis IO dock!

Hi there!
I have an Ipad 2 with the newest OS installed etc. And I rea the other posts in here.
I bought an IO dock from Alesis the other day and was full of exspectations, but I got a bit disappointed -> Garageband! When I bought the Ipad dock I exspected that I would be able to record (or just play and hear the inputsound from two devices) at the same time in my headphones! But I wasn't... Now I'm wondering if this is going to be fixed in an update or not? I think it would be a shame if this issue isnt adressed, due to the huge abilities the Ipad/garageband/Ipad docks withhold.
So anyone know anything? I went to my musicstore and spent about an hour or so with the tech dude there trying dfferent setups, but unfortunatly without luck! Just to clarify that I didt just plugged in my guitar and got mad that it wasnt apple intuative!
Hope someone can help :)

I am wondering if I can record audio and midi at the
same time in Logic 7 Express. I am running my guitar
thrugh a Roland GR 33, and a line out and using the
GR 33 to trigger sounds in the Logic's synth section
but cant seem to record all three tracks at once. If
any one knows how let me know. Oh and I am running
the GR Synth and Guitar into the Prosonus Fire Fox
and have the GR 33 out midi to the Fire Box as well.
So I guss the question is how do I sent up two audo
tracks and one midi track to record in real time.
Thanks Victor
Try arming the audio tracks, select one of the tracks, then while holding down the shift key, select the midi track you want to record, arming the "r" on the midi track. Press "record".....

Is there a way of resizing the contents of multiple bounding boxes at the same time using the number fields in the tool bar?

I'musing cs6 and need to resize an image and two text boxes to a specific pixel width.
I try selecting all of the boxes and punching in 960 px in the resizing field in the tool bar but only the bounding boxes and not their contents get resized...

Use the horizontal scale field (and include the units) rather than the width field.

I am in the middle of a job using CS 6, but at the same time opening the Creative Suite apps. I created an InDesign file in CS 6, saved it, and now I can't open it. I'm getting this message: Cannot open file because it was saved with a newer version of A

I am in the middle of a job using CS 6, but at the same time opening the Creative Suite apps. I created an InDesign file in CS 6, saved it, and now I can't open it. I'm getting this message: Cannot open file because it was saved with a newer version of Adobe InDesign CC (10.1). You must use that version or later to open the file." AARRGGHH! So how do I access the file?

Sounds like you opened and saved it in CC, so now you need to go back to CC and either complete the project there, or export to IDML to take it back into CS6.

Is there a way I can stream video from my 2012 AirMac to the Apple TV using airplay and at the same time stream the audio to an air speaker?

Is there a way stream video from a 2012 MacBook Air to a TV using Apple TV and at the same time steam the audio to an air speaker. Also the same question but using an ipad

You can try one thing. Follow these steps:
1. On your Mac, turn on AirPlay Mirroring and connect it to the Apple TV, so audio and video will stream from the Apple TV.
2. Turn off the sound of the TV where you have connected the Apple TV.
3. Then, make sure that you have turned on the AirPlay speakers. Then, open System Preferences > Sound > Output, and choose the external speakers, so sound will stream from these external speakers.
This should work correctly

Can you use 2 sets of bluetooth headphones at the same time with the Ipad 4?

Welcome to the Apple Community.
Unfortunately you can't do that.

When our iPad is in use on the internet, my iMac internet connection goes off. I can't get the two devices to work at the same time with the AirPort Express. Is there a setting somewhere I may have missed?

When two or more devices conflict it typically means that the DHCP service is either misconfigured or is not running at all. DHCP provides IP addresses to local network clients.
Is your AirPort Express base station the only router in your current network configuration? That is, is it connected directly to an Internet modem and not to another router upstream of it?

Can i run two widgets at the same time on the same page?

Can i run two widgets at the same time on the same page?
Hi
I have created and published 4 free ibooks and i would to run two widgets
- a countdown clock
- a review test
at the same time on the page. Can i do that?
Thanks in advance
Haris

thanks for your answer. Yes indeed HTML widgets run only full screen (snif snif). I consider this as a "distinguishing treatment".
One solution i read !!!!! was to create through keynote a countdown clock, to export to quicktime move and to imported at iBA predefined widgets. of course this is not the solution i need.
So, in order to have at the same widget and run together a count down clock and a preview test (20 questions) i must
1)"hack" the preview widget and insert a countdown clock
2) create a preview test using iAD.....
thanks again

Can you play 2 songs at the same time using itunes?

I would like to put music under my audio books and my question is "can you play 2 songs at the same time using itunes?"

I am not aware of a way to play two songs at once in iTunes. However, at least on a Mac, you can definitely open and play multiple things in QuickTime player. Sooo, you could open a music file in QT Player then start it and start the audio book in iTunes. Or open the audio book in QT player and listen to that there while iTunes plays music.

Is there a way to show two angles at the same time in the final edit rather than switch between them with Multicam?

Can I show two angles at the same time in the final edit rather than alternate with Multicam?

Stack two clips on top of each other and reduce the sizes. I think that's what you want.

My ipad identifies my charging cable as not recognized, although it was bought at the same store, at the same time as the ipad. It charged for awhile, but now won't turn on or even charge. Any ideas?

My ipad identifies my charging cable as not recognized, although it was bought at the same store, at the same time as the ipad. It charged for awhile, but now the ipad won't turn on or even charge. I still have all the packaging and receipt as proof. Any ideas why? Purchase was over a year ago, so I can't get Apple help on the phone.

Try moving and wiggle the devise if that works the port or the tip of the charger is Brocken if the wire is an apple chatter made by Apple it should not I give your problems I've it in a forren ore different manufacturer that could be the problem apple suggest all apples devises should all ways charges and sync with an apple manufactured charger for the best proformance don't try other doggy chargers made from other manufactures.
Hope this works
