Two Ni4472's in system, one swings to 10V, the other 6V, Bad Card?

I have two NI 4472 Cards in my system, one swings 10V signal from a transducer in all channels, and the other only 6V, the problem follows the card.
Do I have a bad Card or Am I missing something, I am using Lab View. Run-time 6.1, 7.0 and 7.1.
Thanks for the help.

Hi Rafael,
The NI 4472 has an input signal range of +-10Vpk. If you have two NI 4472s in your system, and the same input connected to both, it is likely you have a malfunctioning DSA device. A good method to test the device is to open the Measurement and Automation Explorer (MAX) and reset the device, self-test the device, and verify a sine wave input is the same on both 4472s.
Hope this helps,

I have two very similar iMacs but one performs better than the other. Any ideas?

I have the latest Premier CC on two systems, my 27" i7 iMac w/16 GB RAM at home, and a 27" Retina i5 iMac w/32GB RAM at work. Both are running Yosemite but I don't quite get the performance on my home system as at work. Both are using Mercury openGL. The graphics cards look comparable, far as I can tell -- both have 2GB vram. So the only thing left I can think of is the RAM but before I go spend that money and kill myself if it doesn't make any difference, anybody have any thoughts?

Hi Scott, thanks for the quick reply. I chatted with an Adobe support person who said the extra RAM would only make a difference in "Mercury playback software only" mode. (Of course, this is the same support person who said, unequivocally that "...rendering is always necessary, sir" just after I'd told him that I never have to render on my office system, just my home system, so I'm skeptical he really knew what he was talking about...thus, I'm here in the forum now!)
ANYWAY...sorry to be so lame, but could you clarify how to set cache disk settings? I found memory allocation prefs -- it was set for 12 GB for Premiere, 4 for everything else. I changed it to 13 premiere/3 everything else -- which is all it would allow me to do -- but it doesn't seem to have made a difference. Also, it behaves the same way even if I'm running no other apps at all so not sure the background tasks diagnosis is a factor, but I could absolutely be confused about some key thing you're talking about!

I have a fairly elderly I Mac 7.1 (2.47 Ghz Intel Core Duo) operating OSX v 10.9.5. At the core level I find two Library folders, one within the System Folder and one by itself with the other core level folders - mostly same content. Is this right?

The system is slow.

I have two apple accounts on one computer. How do i delete one account without deleting the other?

I have two questions!!
I need to know how to delete one account without deleting the other account on the computer?
I am deleting the account because i have a new laptop that now has the my account... will deleting the account on one computer affect the account on the other laptop?

What do you mean by deleting the account? One can't delete an Apple ID/iTunes account. One just stops using it.
Since yo can only have five computer authorized for one iTunes account you might want to deauthorize the computer for that account

All content and data is forever associated with the Apple ID you used to download it. You should have reset the password for the original I'd.

I have duplicate pictures in "my catalog" that I believe come from two Adobe folders found under "my pictures/adobe/ one is Revel and the other is Photoshop express which preceded revel. Can I delete those two folder without causing a problem with my catalog?

Thanks for the links, Limnos.
If you are willing to continue helping, here's what I found.
Just to clarify the two iTunes folders I am refering to are:
username-->Music-->iTunes
HD-->iTunes
I am presuming each location has a full set of files as outlined in the above links?
Not all the files are in both locations. Most are.
- The Itunes folder in my home folder does not have itunes library.xml.
- The Itunes folder in my home folder has a subfolder called Mobile Applications (username-->Music-->iTunes--> Mobile application). The Itunes folder at the HD level also has a Mobile Application folder but it is a subfolder of Itunes Media folder (HD-->iTunes--> iTunes Media-->Mobile applications) and has no files in it.
- I do not have an iTunes Media in the iTunes folder in my home folder.
- also the Itunes media folder (HD-->iTunes--> iTunes Media) has subfolders by type (books, movies, itunes u, music etc...) but the iTunes Media-->Music also has some of the same subfolders ( iTunes Media-->Music-->books, iTunes Media-->Music-->Movies, iTunes Media-->Music-->iTunes U). Is this normal repetition?
You say:
/itunes/itunes media/ music
but it is important to note what comes before all that.
There is nothing as far as I can tell before that first forward slash. Since the only iTunes Media folder I have is in the iTunes folder that resides at the HD level (HD-->iTunes--> iTunes Media folder) not the iTunes folder in my home folder (username-->Music-->iTunes) , I assume that's the one that holds the music.
Keep iTunes media folder organized and Copy files to iTunes Media folder when adding to library are both checked on
Does that give more clarity into my problem?

Hi I am hoping to add my 2 TB time capsule to my existing wireless network using cisco dpq 3925 modem. I have two mbp one running Yosemite and the other os 10.7.5

I have a time capsule 2TB model 1409. I would like to connect it to my existing wireless network (using a cisco DPQ 3925 modem). I have two mac book pro one running Yosemite and the other OS 10.7.5. The best I can do is to connect the TC to the Modem via ethernet. Have one of my MBP connect to the time capsule using a ethernet cable and have the TB set to bridge mode. In this configuration, both mbp and the iPad can detect the TC but when I try to connect it to the wireless network, using the same network name and password, the light flashes amber and I cannot detect the time capsule again.

Correct..
The best I can do is to connect the TC to the Modem via ethernet.
The TC does not connect to non-apple routers by wireless.. well. It is possible but so poor a method that Apple seem to have eliminated it in the setup wizard.. I would take that as a good thing..
If you cannot use ethernet you have two choices..
Use another apple router that is plugged into the Cable modem.. eg a second hand Extreme Gen5 or the latest Express.. the Extreme is both cheaper and better.
Or you can use a set of EOP (homeplug) adapters.. but they cannot be guaranteed to work so you should buy from a place that allows returns.

Two http ports - one in 8080 and the other one in 3034 - How to remove 8080

Hi!
I have two http ports - one in 8080 and the other one in 3034 - How to remove 8080.
Listening Endpoints Summary...
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=<ip address>)(PORT=<port number>)))
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=<hotname>)(PORT=3034))(Presentation=HTTP)(Session=RAW))
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=<hotname>)(PORT=2102))(Presentation=FTP)(Session=RAW))
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=<hotname>)(PORT=8080))(Presentation=HTTP)(Session=RAW))
Services Summary...

You get check which is the current dedicated HTTP port by using DBMS_XDB.getHTTPPort(). There can be only HTTP port active per database (not taken into account the HTTPs one). If two or more exists than there is still a process claiming that port (in this case 8080). It will be cleaned up after one or more processes are not claiming that port again. New connections will be redirected to the new port.

HT1386 How do I switch users on wifi sync for example my Mac has two users one apples MacBook pro the other is my name I want to switch from apples MacBook pro to my name how is this done?

How do I switch users on wifi sync for example my Mac has two users one apples MacBook pro the other is my name I want to switch from apples MacBook pro to my name how is this done?

Try connecting the iPad to the computer that you do not want to WiFi sync with and uncheck the WiFi sync option in iTunes. Then click on Apply. Reboot the iPad and see if that does the trick.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Encrypted message on one Mac, but not the other, from same server

I run Mail.app on two Macs, both getting mail off the same Exchange server. Multiple times in the last few weeks, a message will download to one Mac and be fine, and then the other Mac will retrieve the message, and it will suddenly be encrypted. Before a bunch of garbled text, something like the following always appears:
--000_25539419161D7744ABC322B480ED5DA507650F7Acmhprdexc04netj
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64
If you go to Webmail on the server, the message reads fine. And it is readable on the other Mac. I tried going to View/Message and choosing "next best alternative" but those options are grayed out. Could there be anything else set locally that is making the email unreadable on one machine but not the other? The unreadable version is always on this Mac (a Mac Mini) and not the other one (a MacBook), even though both are running the same OS version and Mail.app version.

Navigate to your Applications folder.
Right Click on iTunes and select Show Package Contents.
Navigate to Contents/MacOS/
Double-click on iTunes Helper(to get it running). This allows iTunes to start when you plug in your iPhone.
Open System Preferences and go to Users & Groups.
Select the Login Items tab to view the list.
Drag iTunes Helper from the Finder into the Login Items to get it to run at login.
Delete it from Login Items on the Mac you don't want it to start iTunes on.
