Any reason to scan PXI-2575 and SCXI-1127 in a particular order?

Hello-
Is there any reason to prefer one scan-list order over any other? specifically is it better to scan through ch0, ch1, ch2, etc rather than randomly?
It doesnt seem like it would matter.. but many DAQ devices behave strangely if you scan them in ascending order (eg 0, 1, 2) and thus I always scan them in descending (e.g. 7, 6, 5, ...)
thanks-
brad

Brad,
Simply based on the switch modules, there should be no difference in which scan list is prefferable.
Can you elaborate on the strange behavior you have seen on some DAQ
devices? The only interesting behavior I can recall that may be
fixed by scan order is when certain channels are saturated and "ghost" onto other channels. If this is the case, follow the steps in the linked KnowledgeBase to remedy the problem.
What data acquisition device are you using along with your switch modules? What types of signals are you measuring?
Have a great day!

Test after taking each of the following steps. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
6. In some cases, the problem has been resolved by repairing permissions on the startup volume.
7. Turn off Bluetooth and test.
8. Reinstall OS X.

Any reason to keep wireless router and Time Capsule

So my cheapo Seagate drive just died on me, and I'm scrambling to backup my documents and photos to an old 120GB HD and DVDs. It has a 5 year warranty, and I'll ship it in, but I'm guessing it will take a month or so to get back, and I'm less impressed by a drive that failed in less than a year.
So now I'm looking at a Time Capsule with"server grade" storage, does this mean it's more reliable or just advertising gimmick? I already have a Wifi-N router, so I don't need another router, but I also don't want to replace a cheapo external hard drive every year.
If I get the Time Capsule, is there any way to use both routers for a larger wifi range? I have dead spots on the far end of my house and in the basement, or will the Time Capsule be too redundant, maybe I just need another external HD and I'll just rotate between them when they fail.

Sorry you've had a problem, but all drives fail, eventually. Any manufacturer will have some fail fairly quickly, and some live practically forever. Seagates generally have a good reputation, and I don't think any of the other majors have more than a 2-year warranty.

I can't tell you much about Time Capsules. You may want to browse and/or repost in the Time Capsule forum, hidden in the +Digital Life+ section, at: http://discussions.apple.com/forum.jspa?forumID=1253
But the idea of rotating between hard drives is an excellent strategy, that many folks employ. Use one for a week or so, then take it to your safe deposit box, workplace, relative's house, or other secure off-site location and swap with the other one. All you have to do is use the +Change Disk+ button in TM Preferences, and try not to go more than about 10 days between swaps.
That also protects you, of course, against fire, flood, theft, and direct lightning strike on your power lines.

Any reason why ipad 2 32gb and 64gb is not being sold, less the refurbished ones?

As stated in the title

I'm aware of your second link. It is factually an iPad 2. iPad 2,4 marks the 4th hardware revision of iPad 2. What's interesting is that Apple is leveraging on the demand of the iPad's predecessor to "test run" newer technologies like HKMG adopted by Samsung Electronics in the recent years. I'll explain more.
In layman, HKMG essentially allows shrink the die of the processor. By packing the instruction set and everything on a smaller semiconductor, it results in material savings and various other performance benefits with the main one being
Power savings, as mentioned in the link (I'm already aware too) due to operating efficiency (good use in the future)
Better thermal management - the natural effect of reducing inefficiencies also leads to less heat production
Bottom line is, this technology is fairly new. Definitely, Apple wants to put newer processors like the A5X or any other future processors on a 32nm architecture because the natural efficiency benefits will help mitigate power consumption issues stronger chips may cause. But, Apple is testing the water by putting this on an already stable iPad 2 running a stable A5, that's why they don't making a "A5 v2" available to iPad 2.
I also have to tell you, it's a true litmus test or water test. The New iPad's A5X runs on 45nm. Which shows they aren't really ready for the technological advancement. Apart from this change, the iPad 2's still an iPad 2. If you haven't considered the iPad 2,4 an iPad 2, you should.
The iPad 2s should still be available. Look around regional Apple sites. I'm seeing them on mine as well.

Any reason why I should use Safari on my PC

I use Mozilla now. I now have an Iphone. Is there any reason why I should download and use Safari on my PC? I expect the functions will be different from IE or Mozilla or maybe better, but is it a good idea to download and use since I have an Iphone?

It's pretty irrelevant, unless you really want to sync bookmarks from your computer to your iPhone (you could do that with IE as well, but not Firefox).

Low level control of SCXI 1127 relays

Hi,
How can I close or open switches HLSELECT and 1WIRE of SCXI-1127 manually? There is a VI(1WireINDEP) which uses CIN to activate these switches. This VI allows to activate HLSELECT and 1WIRE relays when the SCXI 1127/1128 is used in 1 wire mode as a 64x1 multiplexer. The 1WIRE relay will always connect to 1wirelowref signal. The HLSELECT will connect to Com0+ when H-L Channels is set to Channels 0-31 and to Com0- when H-L Channels is set to Channels 32-63.
I need to control 1WIRE relay just like this VI controls HLSELECT relay. I have attached this VI. Can you please modfiy it or write a different VI to allow controlling 1WIRE relay. I should be able to open and close these two relays (HLSELECT and 1WIRE) manually thro
ugh the VI. If this is not possible, can we modify this VI so that the 1WIRE relay will always connect to com0- signal instead of 1wirelowref signal.
Thanks

Thanks for your reply. My problem is not that simple.I am using NI-SWITCH1.6 and need to continue using it. Can't I just use this VI as sub VI and call it? Here is my problem:
I am building a system to test cables that are open at both ends. A cable can have 4, 6, 8, 10, or 20 wires in it. I wish to test the resistance of each individual wire in a cable and insulation between wires. I have four SCXI 1127 modules with SCXI -1331 in a SCXI 1000 chassis. The switches are controlled by a PCI-4060 DMM.
I have written a VI ( in Labview 6.1, NI-SWITCH 1.6, NI DMM 1.6), which configures DMM for multipoint measurement and SCXI 1127 modules in scanner mode. I connect 1_WIRE_LOW_REF of all SCXI-1331s to a common point, which connects all wires in a cab
le/s under test. So, by using SCXI in scanner mode and generating scanlist, I can measure the resistance of individual wires. I use 1127 in 64 x1 multiplexer mode. This takes care of one requirement.
Now for insulation testing, I keep all wires of cables connected to switch channels and need to connect them in combinations. I can generate the combinations and pass it in a loop to close or open switches. I need help in creating correct paths and route the measurements to DMM.
For example:
Let�s say, we have a four wire cable, I need to test the insulation between them in pairs. There are six possible combinations: 1-2, 1-3, 1-4, 2-3, 2-4, 3-4. Let�s say these wire are connected to ch0, ch32, ch1, ch33 of module 4, the VI may need to close the switches as per the paths required (attached in word document).
I just don't know how can it be done.

Handshaking Scanning with PCI DMM and SCXI

Hi,
I am trying to implement handshaking scanning with hardware that I have. Here's my setup:
My software : NI-DMM 2.5, NI-SWITCH 3.0.49161, NI-DAQmx 8.0.0f0, NI-VISA 3.4, VC++ 2005 Express.
My hardware : PCI 4070, SCXI1000, 2 SCXI1127, SH9MD-AUX cable and SCXI 1359 kit.
First I am trying to run the example called niSwitchDMMSwitchHandshaking.c. I am getting an error message that says:
"Sample trigger or trigger source cannot be set to external when the device is configured for SCXI control"
My setup uses PCI-4070 as a chassis communicator, but this is not something that I can change. How can I solve this?
Another related question is do I need to make any additional electrical connections? One of the functions sets trigger attributes to FRONT_CONNECTOR but the "Scanning Switch Modules" document explains that "AUX I/O can be used to control an SCXI chassis and to sent and receive triggers", and that would be my prefered setup. What do I need to do?
Thank you for your prompt help.
Jerry.

You are correct, I had missed this detail of the SCXI-1127's
operation. Since you are using a PCI-4070, it is not possible to
use the PXI-1011 chassis with your current DMM. The best solution
I could recommend would be to use another device, such as a USB-1359 to
control the SCXI chassis, then the AUX Connector on your DMM will be
available to make the trigger connections needed for handshaking with
the SCXI-1127 switch. Keep in mind; however, that you will only
be able to handshake with one of your switches using this method.
I believe that you are already working directly with another Engineer
at NI, so I will allow him to assist you from this point forward.

I have used Image Capture to scan images/documents and then saved them as either PDFs or PNG files. For some reason, just this past week Image Capture will no longer save the file. It scans, and the Scan Results window pops up, but it won't save file.

I have used Image Capture to scan images/documents and then saved them as either PDFs or PNG files. For some reason, just this past week, Image Capture will no longer save the file. It scans, and the Scan Results window pops up, but it won't save file.
The file name has no special character in it, just letters and no spaces.
I have done this in the past and it has worked, but now it will not.
I have not upgraded any software, that I am aware of.
After scanning, the Image Capture pops up the Scan Results with the file name in the window, but neither the Scan Results nor the Image Capture window responds to inputs. The Image Capture window is frozen, with only the "Overview" and "Cancel" buttons active (but non-responsive).
Is this a software issue or a scanner hardware issue? I am using a HP Photosmart C6200 series printer/scanner on a network using a Time Capsule airport.
Thanks.

I had the same problem.
Got a 90% fix. Apparently the Mavericks preferences won't work with Yosemite, so I just deleted the Image Capture preferences.
Unfortunately, the "Scan to" folder seems to be permanently set to the Pictures folder.
1. Quit Image Capture
2. Go to Finder > Go > Home, which opens up your home folder (named after your user name)
3. Open Library > Preferences > com.apple.ImageCapture.plist - Drag this file to the Trash
4. Start "Image Capture", click "Details" and change all your settings as you prefer
5. Quit and restart "Image Capture". Notice it remembers all your settings except "Scan to" folder. It insists on saving to "Pictures".
That's as far as I was successful. I tried changing the "Scan to" folder to "Desktop", but on launch, Image Capture always sets it back to "Pictures".
This is what I tried:
6. Download and install "Pref Setter" from http://www.nightproductions.net/prefsetter.html
7. Quit "Image Capture". Right-click on "com.apple.ImageCapture.plist" and open with Pref Setter.
8. Search for "Pictures", which finds "~/Pictures" (the tilde character at the start means your home directory).
9. Double-click on "~/Pictures" and change it to the folder you prefer. I like "~/Desktop"
10. Choose File > Save then Quit from Pref Setter. Note that re-opening the plist file still shows "~/Desktop"
11. Start up "Image Capture" -- on startup, "Image Capture" sets "Scan to" folder to "Pictures"
I consider this a bug.

Can't configure a SCXI chassis (PXI-1010) with a PXI-8176 and a PXI-6052E.

I have a PXI-1010 chassis with a PXI-8176 running Windows 2000. In the rightmost PXI slot, I have a PXI-6052E. The remaining PXI slots are either empty or have misc. modules in them. I have a SCXI-1520 in the leftmost SCXI slot.
I am trying to get MAX to recognize my SCXI chassis with the SCXI-1520. When I try to add the SCXI chassis in MAX by right-clicking "Devices and Interfaces" or "NI-DAQmx", I leave the communication mode to communicate on the PXI backplane, choose SCXI slot zero, and find that the communication device field is greyed out where I want to choose the PXI-6052E. For some reason,the wizard used to add an SCXI chassis does not see my PXI-6052E pluged in to the leftmost sl
ot. Strangely, MAX does see the PXI-6052E in the "Devices and Interfaces" tree. I verified that the 6052E is working correctly. I also verified that the pxisys.ini file is in the WINNT directory. What is the problem?

I am first trying to install the SCXI chassis using the SCXI 1520 user manual. I put a PXI-6052E in the right-most PXI slot and the SCXI 1520 in a SCXI slot. On page 1-12 of the SCXI-1520 user manual, it instructs me to power up the chassis, right-click on MAX "devices and interfaces", choose the correct chassis, and click finish. The problem is, after I click finish, a window appears that forces me to choose a DAQ device. The SCXI chassis doesn't configure correctly because the wizard doesn't see the PXI-6052E.

Lyall,
I have seen this before, a long time ago (several years), and I cannot
remember how/if we resolved it.
If this is an impotant issue to you, I suggest that you open a case with
BEA support.

Peter.

This is a rather important issue, I have seen another post with a similar problem.
While not being a show-stopper it certainly raises concerns.
The application works ok until the application exits (in both development and

Apparently this did not happen with Tux 7.1
It does with 8, I do not have 7.1 so I have no workaround.

Is there any reason photos in an album page display small on the iPad, but normally on an iMac? And videos on a movies page don't play on the iPad, but are OK on the iMac?

Is there any reason photos in an album page created in iweb display small on the iPad, but normally on an iMac? And videos on a movies page don't play on the iPad, but are OK on the iMac?

there are three displays in photos page:
1) thumbnails grid - smallest
2) deatial view and detail view slideshow - large
3a) pop-up slideshow - vary - this is slideshow.html
3b) or iphone/ipad slideshow phoneshow.html - iphone/ipad can't do pop-up
it's difficult to know which you refer to.
if you refer to pop-up slideshow then you should not look into iwebmediagrid.js as wyodor suggested.
instead look in phoneshow.html and change width and heigth of element id slideshow:
#slideshow {
position: relative;
width: 320px; /* this is default width */
height: 360px; /* this is default height */
margin-left: auto;
margin-right: auto;

I have Windows 7 and recently everytime I try to update my iTunes I get an error message. Any reasons why?

Hi! I have a PC running on Windows 7 and recently I can not upgrade my iTunes. Any reasons why?

Many thanks, that's perfect.
(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?
