Lab PC 1200 AO with different polarities

Hi,
I'm trying to configure a Lab PC 1200 card to have one AO channel bi-polar
and the other unipolar (WinNT NI-DAQ 6.5.1). I'm sure I used to be able to
do this, and the manuals imply that it is possible, but I can't see how to
do it with NI-DAQ 6.5.1. Can anyone tell me how to do this ?
Thanks

"On the same note, I'm attempting to write a program that takes inputs from two PC-1200 cards. When running the program it works fine but then every one in a while it switches which port it inputs and outputs from. Can anyone help me?"
Are you taking digital inputs? What do you mean it "switches which port it inputs and outputs from"?
Please let me know your results.

Counting TTL pulses from 10 Hz to 3000000Hz with LAB-PC-1200

I want to count TTL pulses from an electron analyser. How can I use the DAQ wizard to connect the analyser to the PC-1200 and look if it works?

Augerspectro,
The counter chip used on the Lab-PC-1200 is the 8253. Thus, you will be able to use any of the 8253-counter examples available in LabVIEW. To count pulses, I would suggest that you examine the Count Events (8253).vi example. With regards to the required hardware connection, this is discussed in the device's user manual (link available below).

Lab-PC-1200 not responding in Win2000

I was using a functioning system using a Lab-PC-1200 DAQ card and Win98 and LabView 5.1.1. I upgraded the computer to Win2000, and now I am having problems.
When I first run my application, everything seems fine (I read my analog inputs from the card correctly), but when I run a portion of the application that involves data collection in a While Loop, I get an "Error -10452 @ AI Single Scan. NI-DAQ LV: No inerrupt level is available for use."
After a while of trying to troubleshoot that problem unsuccessfully, I try to go into M&A Explorer and Test Resources and get "The device is not responding to the selected base address." I was not getting this error before.
So my first goal is to find out why the device is no longer re
sponding. I am running NI-DAQ 6.9.3. In the Win2000 device manager, it says everything is operating correctly. I have tried rebooting, reseating the card, deleting the device then rebooting to re-install the drivers, and nothing seems to work.
I have read through several other complaints of similar problems, but no solutions yet. Any other ideas out there?

Hello,
I was able to find a document which is similar to your problem, although a different operating system. It sounds like for your case, you have an IRQ assigned, so that will differ from the information that I found. Regardless, I will post it for information that could assist you. I suggest checking the resources and seeing if there is anything else that is sharing your resources. If there are, either assign a different IRQ (if available) to your device, or disable the devices that are sharing. The other suggestion that I have for you is to try the device in a different computer to see if you can isolate the problem to either the board or the computer. If it is the board, then you can send the device in for a repair.
Good luck.

================================
The following trick was used on a Windows98 machine to assign an IRQ to a Lab-PC-1200 board (AT-interface) when no free IRQs were available. The lack of free IRQs caused an error -10452 during any buffered acquisition. In this case, we deliberately created a resource conflict with LPT1 and the DAQ Card, both using IRQ 7, to get the DAQ card working. The "trick" is to know that the user cannot simultaneously use LPT1 and the DAQ card and live with the conflict. Before trying this procedure, confirm that the DAQ card installed properly, and the only problem is the lack of an IRQ assignment to the card because none are available.
1) In Win9x, enter start >> settings >> control panel >> system >> device manager >> select "computer" >> properties >> select "View Resources" and IRQ. Browse the list and determine if any free IRQ levels are available - also determine what resources which are currently used are not needed. (*note : do not mess with any entries that you do not understand). In this case, the user identified LPT1 as a used resource that he would not need. Press "cancel" to get back to the device manager tab.
2) In the system control panel device manager, select the DAQ card lacking an IRQ resource under "Data Acquisition Devices". Select "properties" and go to the resources tab. Uncheck "Use Automatic Settings" and select a configuration that allows entry of an IRQ. Select IRQ and press "Change Setting", scroll through the list of IRQs until you select one used by a device that you know you can live without. In this case, we selected IRQ 7 for LPT1. (note - you can also try reserving IRQ resources under the "reserve resources" tab).
3) Reboot the computer.
4) Enter Device Manager again - observe that the two devices are now showing a conflict on the selected IRQ - this is normal and on-purpose.
5) Enter Measurement and Automation Explorer (MAX). Select the DAQ card and test resources. The device should now pass the test.
Other Suggestion:
In the BIOS, some computers allow you to select PCI only, ISA only, or both PCI/ISA for various slots, and thus reserves resources for those slots. You may be able to enter the BIOS and select "Both PCI/ISA" to free resources for use with ISA cards if they are reserved for PCI cards.

What is the Analog Ouput FIFO size of the LAB PC 1200 ?

Hello,
does anyone know what is the Analog Ouput FIFO size of the LAB
PC 1200 ? I can't find anything in the documentation nor with "Get DAQ
device information" vi.
Thanks.

The Lab PC 1200 does not have an analog output FIFO.

Connect 2 externa monitors with different resolutions?

Is it possible to oonnect 2 external monitors, with different resolutions to a mbp pro?
I've read some about the "matrox solution", but that one requires that the monitors uses the same resolution.
And, just to be clear, I don't want to just duplicate the screens, one should be primary.

You may want to phone OWC and ask whether what you want to do is possible if one monitor is connected to the mini-Displayport and the other is connected to a USB port using this adapter:
http://eshop.macsales.com/item/Other%20World%20Computing/VIDU2DVIA/
Note that the OWC adapter, like most USB video adapters I've seen advertised, is limited to a maximum resolution of 1600 x 1200, so you won't want to use it with a monitor whose native resolution is higher than that.

Lab-PC-1200 ISAPNP

Lab-PC-1200 is not detecting in win98. Can I install 1200 manually?
Is Lab-PC-1200 driver for win98 supports Intel chipset 815?

Hello Sajen,
What version of the driver are you using? For that particular DAQ board, you will need the 6.9.3 driver.
Have you successfully installed this board on another machine? I do not know of any incompatibility with the Intel 815 chipset.

Hi, i am trying to open and view a report that comes from another server with different odbc connection

hi, i am trying to open and view a report that comes from another server with different odbc connection
i created a crystal report for a mysql database on my machine and everything works great
but we have other reports that come from other machines with different odbc connection
and this its not working when opens the report asks for credentials
and i cannot use the remote ip for these reports that come from other machine
question
if i cannot connect to remote ip to open the report
for each report i have to create a database the report database on my machine and then open the report ?
or there is some other way to open the report ?
i am using visual studio 2013 and mysql and
<add key="MYSQLODBCDRIVER" value="{MySQL ODBC 5.3 UNICODE Driver}"/>
thanks

short
i have a report that it was created on another server with a specific dsn
now i am trying to open the report on my machine
the database from the other server does not exist on my machine
the server machine where the report was created the ip its not accessible
question ?
can i open the report on my machine or its impossible ?
thanks

How can I transfer contacts from one iPad to a new iPad with different iCloud addresses?

One way would be to e-mail them from yourself to yourself. That would totally avoid the different ID issue.

How to backup multiple iphones with different iCloud accounts but same apple id?

I would like to back up 3 idevices each with different icloud accounts to itunes. But they use the same apple id so that itune purchases can be installed on each device (2 iphones and 1 ipad).
All I want to do is create a backup in case the phones need to be restored. I also want to back up before downloading iOS 8.
The Macbook Pro that I will back up to has one user and one itunes library.
Is this possible without mixing up address books and contacts etc? Appreciate if some one could direct me to detail step-by-step instructions if they exist or please tell me how I can do this.
Thanks.

With Family Sharing they don't need to have the same Apple ID anymore.
But backups to iTunes are kept separate among multiple devices; Apple ID and iCloud isn't involved at all. Just make sure the devices do not have the same name.

Can i use 2 ipad's on the same itunes account with different apple accounts?

Both me and partner have an ipad 4. Though we only have one computer, can we use the same itunes but with different apple acount without any issues? We use some of the same apps, but my partner plays fx Baldus Gate and is worries that save files will be corrupted.

Each iPad should be linked to its owner's personal, private and nonshared AppleID. In the Mac, each one should have a different login account so each has their own iTunes Library containing your iPad's details. When you use iTunes on the Mac, since each logs in with a different login and corresponding Home directory, iTunes picks up the correct AppleID.

Welcome to the Apple community.
iTunes and iCloud and different accounts, you will need to delete both accounts from your device before adding the new details in their place.
For iCloud go to settings > iCloud, scroll down and hit the delete button. You can then sign back in using your correct details. For iTunes go to settings >store, tap your account ID and then sign out, you can then sign back in using your correct Apple ID.

Photos. They are on my macBook, backed up on time machine. Copied them (hours and hours) to external hard drive. They are now in alphabetical order (19,000 of them) NOT IN THEIR EVENTS or date order-and have been taken with different cameras- help!!!!!!

Photos.
They are on my macBook, backed up on time machine. There are 19,000+ of them, some rescued from a pc crash- which I used the nifty iPhoto to put back into date order.
I want to take them all off my laptop, now............as I need to use it for WORK!!
Copied them (hours and hours) to another external hard drive.
They are now in alphabetical order (all 19,000+ of them) NOT IN THEIR EVENTS or date order. (-They have also been taken with different cameras over the years and some of the generic camera numbering remains.)
I have tried to copy them (only a few as an experiment) one event at a time, but that again "opens up" the Event "folder" and tips them out as individuals and therefore just lists image letters and numbers alphabetically.
How can I copy
the whole library still in "Events" to an external hard drive?
the folders/albums I have already made on to this hard drive?
and how can I add to this back up monthly, again keeping events and folders separate and updated?
Mac is so user friendly - there must be a way.........
Thanks

UPDATE : I have re-installed from disk, various apps that were no longer functioning such as iLife, iWork etc. So, I now can access my photos again.
Also, I had to re-install all the software for my printer ( Stylus Pro 4880 ) and reset it so the printer is working again.
Photoshop CS4 won't open. I think I will have to get in touch with Adobe as basically, I guess they have a built-in "blocker" which prevents me from opening the app as the license is for only 1 user and having re-installed the OS, there are now, in effect, 2 users ( Me and Me 1, I think ).
So, having added on a new external HD, Time Machine has made a copy of most of the files, folders, apps etc onto the external HD. The internal HD is still nearly full ( 220 GBs out of 232 GBs ).
I am guessing the way to go now in order to free up space on the internal HD is to delete/trash older photos from my iPhoto library and hope that if needed, I will be able to access them on the external HD.
Am I correct ? Please advise before I do something I will regret.
Thanks, Sean.

Items in the shopping cart appear with different price than in the catalog

Hi All,
We are running SRM 5.0 (Classic Scenario) with external catalogues.
After selecting items from the external catalogue and transferring them to the shopping cart, the items appear with different price(the problem exists in the productive system)
The strange thing is that there is no dependence or sequence between the differences. For example, in one shopping cart, one item is with correct price, the price of the other item is not correct (when I click on the icon which is showing item details in the catalogue, the price is different than the one in the shopping cart). Sometimes the difference is significant, sometimes not - if the item price in the catalogue is 22.34 EUR, in the shopping cart is 21.22EUR or if the item is 45.62EUR in the shopping cart is 45.60 EUR. There is no logic.
I tried to create a shopping cart in the support system, with the same items from this catalogue, and they are sent back in SRM with the correct prices.
I traced all OCI parameters, sent from the supplier catalogue, and everything is correct.
At the example given below the price in the shopping cart ordered in the productive system is 69.00CZK, and after that during the test the correct price of 73.870CZK has appeared.
NEW_ITEM-DESCRIPTION==Durable-KeyClip-keytag%2C+black

NEW_ITEM-LONGTEXT_1%3A132==Durable-KeyClip%0D%0Akeytag%2Cblack%0D%0A%0D%0A6pc
I checked the error log in SLG1 for BBP_OCI, and no error message exists. In my opinion the problem can be in supplier system, because otherwise all items will be with wrong price. And at the moment, there are shopping carts in which all items are with the correct price!
It is not something in the user profile, because in one shopping cart created by one user some items are correct, some of them not.
I also checked with the supplier, they said that they haven't change the price, recently.
Has somebody of you met this problem?
In the IMG-> Define External Web Services (Catalogs, Vendor Lists etc.) I have set all parameters for the standard call structure: the URL of the supplier, our company ID and password for their catalogue.
In the Detail view for the catalogue, the following parameters are set
u201CAdditional functions in the product catalogueu201D field:
-     Display product data again in the catalogue
-     Validate product data from SAP Enterprise Buyer
-     Find supply sources
u201CTechnical Settingsu201D field
- Use Error Log
Thanks,
Desi

That means that we are not maintaining material numbers in SRM, so there are no predefined price or info records for that materials in R/3 system, or in SRM.
In the set up of external catalogues, validation of the price is set. Which means that, if a new shopping cart is created from already existing one, and meanwhile, a change of the price is done by the supplier in the catalogue, the new item price will be adopted in the shopping cart.
No prices are maintained in the SRM system, everything is from the supplier catalogue.

I need to update my apps in the App Store, but when i try to update, the Sign Up Apple ID pop up box came out with different Apple ID. How can I change it to mine? My iTunes Store already login with my own Apple ID.

Just now you said the other Apple ID stored inside it, is that mean all my data back up in that the other ID?
