Can I get 4-20mA into a USB-9211

I want to set up a USB connected interface to three thermocouples and a pressure sensor.
The pressure sensor could be a 'strain bridge type' with an output accross its differential bridge outputs of 0-30mV (with a common mode votage <5V) or a 4-20mA type of sensor which I suspect with a 3 Ohm resistor could also make a differential voltage that this product could measure.
Critical to this adaption;
a) Is the on-board bias current to the input terminals mentioned in the manual small or stable and predictable?
b) Is there a software mode that reports mV rather than a thermocuple and cold junction computed temperature?
Thanks.

Hi,
The 9211 will only support differential AI from 0-80mV. It will not be able to measure current. To measure an AI voltage you can use the example found under:
Start>>Programs>>National Instruments>>NI-DAQmx Base>>Examples.
In this folder there are examples for the type of API you are using. I used the AI one point.vi for LV 7.1, and measured a voltage from 0-80mV. I hope this helps!

Working alternating with iPhoto and FCE tgrying to import pictures from iPhoto into FCE suddenly all my 22300 pictures disappeared leaving empty frames. Does somebody know where the pictures could have gone and how can I get them back into iPhoto? Lothar

The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

After editing a RAW image in PE13 I can't get it back into my iPhoto library. If edited in iPhoto first and sent to PE13 for adjustments, it can be sent back to iPhoto library. Ideas?

Thanks for answering my question. I always have had RAW checked to an external editor which is PE13 on my Preferences panel in iPhoto.
I probably didn't make myself clear. When I send an ORIGINAL RAW untouched, unedited image to PE13 and do the editing and the
adjustments- (it looks great) and then try and SAVE it and forward it to my iPhoto library, it will not be sent. On the other hand if any editing
at all is first performed in iPhoto and then sent to PE13 for adjustments, and I SAVE it, it asks if I want to Replace this new edited image with
what already exists in my iPhoto library, I click REPLACE, the little wheel spins, I go to iPhoto and the new image is there. PE13 does
accept an original RAW image for editing because it will save it in PE13 in the RECENTLY EDITED column. Ideas? I need to keep my iPhoto
library intact. Ideas? Thanks.

TS4036 I have a Macbook pro and I'm trying to set up my ICloud on it, and when I go to Preferences, there is NO ICloud there. How can I get ICloud back into "my preferences" to set it up?

I have a MacBook Pro, its 1 year old. I'm trying to set up my ICloud on it, and when I go to "preferences", (it says to go to "Preferences" in the instructions,) and then "click" on "ICloud", but my ICloud is not there. How can I get "ICloud back into "my preferences".

Welcome to the Apple Community.
This suggests you don't have the right operating system. OS X 10.7.2 or better is required for iCloud, which operating system do you have.

Hi Michael-
I do not have any problem with using shift registers in timed loops. What version of LabVIEW are you using? Can you please elaborate on why neither shift registers or local variables meet your needs? I have attached a VI that saves a previous iteration and then computes and displays the difference. Let me know if you have problems running it.
Thanks-

That's about what it's supposed to look.
How do You want it to look ?
a. You can change places by using this
b. May be You changed this top right symbol of an hard disk ?
c. or changed the number of frames to be viewed ?
d. OR - it can (at least for me) be so that You think of how it looks in iPhoto. (To me a very common mistake)

I can't get my pictures into the public folder on the iPad 3. Can anyone walk me through the steps?

I can't get my pictures into the public folder on the iPad 3. Can someone walk me through the steps?

Ok, I'll give it a try.
Presuming you already have a Dropbox account, and you have the app on your pad.
Open the app, navigate to public folder. Touch the upload icon at the bottom. It will show you everything you have already uploaded. To upload a new picture, then touch the plus sign at the top right. You can create one or more subfolders to organize it however you want.
Hit the plus sign again if needed, and the photo listing will show up. Find the photos you want and mark them by touching them. Then touch the blue word upload in the upper right.
( the directions assume the pad is in the landscape mode.)
That's really all there is to it. As I typed this I opened and uploaded a couple of pics to get the steps right.

How can I get rid of annoying "Unnamed USB device" messege??

Whenever I boot into OS9.2.2 on my other drive in my dual 500Mhz. G4 I get a usb upgrade messege window:
"Software needed for the USB device "Unnamed device" is not available. Would you like to look for the software on the internet?"
This appears everytime I boot, restart, startup on this drive. I've looked for this "unnamed device" in various places like the extensions folder to delete it but I can't find it anywhere. All of my usb devices are functioning and have been named including my MIDI controller. It would be great if I could get rid of this annoying reminder.......how can I get rid of this???
500mhz. Dual processor (revision B) dual boot Mac OS 9.2.x 1.25gig RAM

I think it's my midi controller. I unplugged iton startup and I didn't get the messege. I've got the right driver installed for it and it's working fine so I don't know why I keep getting the messege. It's annoying to have to answer the question everytime time I startup.

How can I get an mp3 into the music section on iPad without using a computer?

The situation is this: I have no access to a computer. The iPad is all that I have to use. So I have never synced it to iTunes or anything.
I am trying to make a video using the movie making app Pinnacle Studio (iMovie doesn't do enough for what I want) and when it comes to choosing audio files, it shows what's stored in the music library of my iPad.
But here is the problem. The audio is a track I have sent to my own email address as mp3. I want to be able to save it from email into my music folder so that it can then be imported into Pinnacle Studio. But when I click on the mp3 in the email it gives me only options to open it in iMovie or Dropbox. How can I get to use this piece of audio when I can't access a computer? Thanks a lot for any help.

If you don't have iTunes you will need to buy the song from the iTunes store and download it that way. If it is a custom track you may be out of luck. The only way to get a song on your device without iTunes involves jailbreaking it.
iOS is set up to prevent people from emailing each other songs, videos, movies, books, etc. This is how Apple got their contracts with the content providers by promising that they would do what ever it takes to prevent people from sharing content that they didn't pay for.

I moved the project files and now I can't get them back into iMovie 11

I was working on a project but I ran out of disk space before I could finish it. Now, for this very purpose, I have an external hard drive with plenty of space on it. So I tried moving the folder with all my project files onto the external hd, and now iMovie can't find my project anymore. With iMovie '06 it was as simple as hitting "save as" and saving the project to the external hd, but I guess that's not complicated enough for the new version. Now I can't get into my project. I even try clicking on the actual project file, and it goes to iMovie as if the project was about to open, but nothing happens. So I fear I wasted a lot of time working on that project only to have to start all over because I ran out of disk space.
Someone please tell me there's a way to get the project files open again. Thanks

that is a simple one and should be a routine after purchasing a new drive (in a Mac-only environment!):
• on your Mac, Apps/Utilities you'll find Disk 'Utility'
• on the left lane, you'll notice your connected hard drive(s)
• select it, click on the 'erase' tab
• NOTE: FORMATTING A DRIVE MEANS ERASING ALL CONTENT ON THAT DRIVE!
that's why you should do it as step#1 after purchasing a new drive

When playing a slide show there are many nonvisible photos. They appear as "image cannot be edited. The original is offline." Where is it and how can I get it back into my photo library?

How can I get all my images to show in my photo library? When playing a slide show some of my photos have a message "Image Cannot Be Edited. The original is offline."

What version of iPhoto?
Are you running a Managed or a Referenced Library?
A Managed Library, is the default setting, and iPhoto copies files into the iPhoto Library when Importing. The files are then stored in the Library package
A Referenced Library is when iPhoto is NOT copying the files into the iPhoto Library when importing because you made a change at iPhoto -> Preferences -> Advanced. (You unchecked the option to copy files into the Library on import) The files are then stored where ever you put them and not in the Library package. In this scenario you are responsible for the File Management.

Where can I get an internal card reader/usb 3.0/firewire/SATS, etc for my Mac

Where can I get an internal memory card reader?
Is there one that also combines to give usb 3.0, firewire, SATS, etc.?

combo cards are terrible but if you look you will see that Highpoint has a USB3 card, yes; or SATA3 (which is probably better).
FW is slower than any drive in existence now.
multi interface chip cards have never performed well but needed back in their day, like OldWorld PowerMacs and those lacking FW800 and USB2.

Can't get cropped images into printable sizes I.e 6x4, 7x5 etc

I am fairly new to elements and I am having problems with resizing my images. I have cropped some images and want to upload them to say 'photobox' but I can't seem to get the images into the correct size for printing I.e 6x4, 7x5 etc. I have also noticed that I start with an image that is say 7mb in size yet when it has been edited and uploaded it is 700k and rated as a medium quality image ? Any help would be appreciated. Thanks

If you have cropped the image precisely to 6x4, then in the print dialog you need to select the paper size (6x4). If your printer has the capabilitry to print borderless, you can try that as well.

Can't get a Movie into my Library?

I've tried every way, the movie files were originally .avi files and i used a free converter to convert them to MPEG4.
I have tried to drop the file into my library, tried to import, add file to library. everything.
i used to have an HP using vista and that worked, I just got an MacBook yesterday. i don't know if i'm doing anything wrong. or its the computer. please help. thanks

Your post doesn't give much detail about the file you're trying to add to your library, but you should first check to see that it plays in QuickTime Player. If it doesn't, it's probably a no-go. You can also try changing the extension to .m4v if it currently has a different extension and see if that does anything.
If you still can't get this straightened out, then I would suggest converting the original AVI to an iTunes-compatible format using Mac software specifically designed for generating iTunes-compatible videos. There are lots of these programs out there, so have a look on versiontracker or macupdate.

Can't get a signal into garageband using firewire interface? Help

Hi, I'm using a presonus fire studio mobile with a shure sm 57 connected into my mic input 1. The interface is correctly receiving the signal however when I choose the input in garageband i can't get anything. I tried all the input options (mono and stereo) but still nothing. I don't understand why.

Hey Buddy,
Does your interface have a software program that supports it? For example: Apogee has Maestro.
Is the mic a phantom mic? Perhaps tha phantom feature has not been engaged?
Did you double check the audio settings in the Garage Band>Preferences>Audio section?
Another trick might be to restart Garage Band AND/OR restart the machine with the interface connected.
Double check you input settings (ie, Line 1 or Line 2 or Stereo). Make sure the monitor is set to the "on" position. Click the grid icon next to the "monitor on/off" setting and double check your connections.
Hope on of these helps.
