Digital device to use to measure 3.3V logic with 5k pull-up and 10k series resistance

I have a digital instrument with the setup that is shown below. I wish to measure the logic state of the line with a National Instruments device. Which one do you recommend?
Trials and Failures: I tried using the usb-6501 but because of the 5V and 5k ohm pull-up on the insides of this device, I was getting bad readings and was told by my peers that this was the wrong instrument to use. I also tried using the digital pins on the usb-8451 and received the incorrect measurements. I need to figure out why the usb-8451 seemed to have the input pins floating when the logic level I provided as an input was a LOW.
The figure below is a representation of my signal source:

Thank you for the response. Since my DUT is already assembled, it is a little late to add chips. However, a coworker suggested adding a 0 ohm jumper on top fo the 10k resistor. I will see if this works and provide an update.
I was recommending adding the chip to your test circuitry, not the DUT.

Can this device be used as an external hard drive with a macbook pro laptop to use files on the airport?

can this device be used as an external hard drive with a macbook pro laptop and use files on the airport time capsule?

If you mean an AirPort base station other than the Time Capsule, it doesn't have internal storage.
If you mean a Time Capsule, its internal drive can be used for regular file storage but shouldn't be; as with all drives, it'll eventually fail. You're better off using a standalone drive and setting Time Machine to back it up as well.

Hi Leo22,
Does this error occur if you use any of the example programs that come shipped with LabVIEW? I would try opening one of the examples that write data to Word and see if those give you an error. Also, have you tried just putting down a New Report.VI and change the report type to Word? If this simple vi (that's all you need to open Word) breaks, I would check to see if there are any instances of Word still open. Check the task manager to see if any word processes are still open. There should not be a problem accessing Word 2003 from LabVIEW 7.0. If neither of these solutions work, please give some more detail about your application and we can research further. Thanks!

How to solve the error message "Could not activate cellular data network: PDP authentication failure"when using 3g or gPRS on safari with an iphone 4 and latest software updates

Please can someone help me to solve the error message "Could not activate cellular data network: PDP authentication failure"when using 3G or GPRS on safari with an iphone 4GS and latest software updates. I have tried resetting the network and phone settings. I have restored the factory settings on itunes and still the problem persists.

All iPhones sold in Japan are sold carrier locked and cannot be officially unlocked by the carrier. If you unlocked it, it was by unauthorized means (hacked), and support cannot be given to you in this forum.
Hacked iPhones are subject to countermeasures by Apple, particularly when updating the firmware. It is likely permanently re-locked or permanently disabled.

I use to have a iTunes account with my old computer, and I have lost all my iTunes music, some purchased, some downloaded from another source. Now I'm using a brand new computer (Windows) and I have opened a NEW iTunes account, but I now I need to figure out if it is possible to recoup my music content that I originally had. I had, I believe around close to 300 songs on my account ;(......Any help or guidance would be greatly appreciated.
Thanks Again, Ronald

Now remove all your info and update the old AppleiD/iTunes account and use only that account.
You cannot transfer items between iTunes accounts.
You can redownload all the content.

My school has a website. The professor uploads files in Word. When I click on the link at home using Pages, the download window opens with nothing in it and Safari opens with a blank in the address book. What Could be wrong? Wrong set up?

Hi Jo,
If I'm interpreting this correctly, the Word file downloads correctly, but when you open it in Pages, the link(s) which your instructor has embedded in the Word file are not correctly translated into Pages.
If the link shows the actual address, you should be able to copy that and paste it into the location bar in Safari, press return, and get to the website that way.
An alternate route might be to download one of the open source Office applications, OpenOffice.org, LibreOffice, or NeoOffice. These are written to more closely emulate the behaviours of MS Word than Pages, and may provide better support for links embedded in Word files.

Barry

Continue to receive error 1604 and can't use the recover function - help! I have gone through all the steps listed in support and nothing has worked. I am using a usb port I tested with my printer cable and it's fine.

I wanted to update my software this morning and it has turned into a nightmare. I continue to receive the error 1604, which is related to a usb port. I followed all the steps listed in support and nothing has helped. I just plugged in my printer cable to the usb port and it works fine, yet I continue to receive this error and can't use my phone!

A printer does not require power, and does not transfer large amounts of data. So that is not a valid test. It's like saying "if I plug a nightlight into an outlet it works fine, so why do 2 hair dryers on at the same time trip a circuit breaker?"
Are you using a port directly on the computer, and not a hub? If it's not a laptop and it has ports on front and back are you using a back port, which can supply more power?
Have you EVER used this computer to hack or jailbreak ANY iPhone (not necessarily the one with the problem? Or used a program to downgrade the version of iOS on any phone?

Can 2 bluetooth devices be used at the same time for iPhone (one for audio and one for data)?

I have an iphone 5 which actually connects to my car (Infiniti FX35) bluetooth phone system, and I want to know if I buy, for example, the Cobra iRadar (which connects via Bluetooth with the iphone) it can be connected simultaneously with my cars phone bluetooth?
If the car bluetooth manage the phone audio while the iRadar (irad-200) manage data (i think), they can be simultaneously connected to an iphone?

Yes, the iPhone will support multiple simultaneous bluetooth connections as long as they are not using the same profile.
I use a bluetooth heart monitor and bluetooth headset at the same time with my iPhone on a daily basis.

Future support for using PL/SQL core business logic with ADF BC

We want to migrate our large Forms client/server (6i) application to ADF, possibly using a migration tool like Ciphersoft Exodus.
One scenario could be to use ADF BC and ADF-Faces or a different JSF-Implementation for presentation and business layer but keep our heavy PL/SQL-businesslogic inside the Oracle database in packages, triggers, functions and procedures.
This scenario could be chosen due to the huge amount of interconnected logic inside the database (10 years of development; no technical components; any package may access any table and more of this kind of dependencies). The business logic nowadays held in Forms client will be moved mainly into the database as a prerequisite to this scenario.
Choosing this "keep-logic-in-DB"-scenario we need a good support by ADF BC to do so. We know and prototyped that it is possible to call some PL/SQL via JDBC from ADF BC and it is possible to use stored procedure calls for standard business entity data access (ins, del, upd, ..). But this does not solve our problems. We want to reuse core business logic coded in PL/SQL. This is much more than change the ADF standard behavior for an update with an own PL/SQL-call.
Now my question:
Will there be a kind of sophisticated support to use ADF BC in combination with database-kept logic?
If so, when will this happen and how will the common problems of transactional state inside the database and inside the ADF BC be solved? Any plans or ideas yet?
Many other clients do have similar applications built in Forms and PL/SQL and would be glad to hear about a path of direction.
I've read the technical article 'understanding the ADF BC state management feature' which you have contributed to. One current limitation is pointed out there: Using PL/SQL with ADF BC limits ADF AM pooling to 'restricted level' which reduces scalability.
Are you aware of additional main problems/tasks to solve when using PL/SQL heavily with ADF BC, which we have to think about?
Thank you for any response.
Ingmar

My main problem is two 'concurrent' areas holding state in an application system based on DB-stored PL/SQL-logic in combination with ADF BC.
For a new System everything can be made ok:
Sure, it is possible to build a new system with the business logic included in ADF BC only. All long-living state will be handled in the BC layer ( including support for UnitsOfWork longer than the webside short HTTP-requests and HTTP-sessions and longer than the database transactions.
For an old system these problems arise:
1. DB data changes not reflected in BC layer:
Our PL/SQL-logic changes data in tables without notifying the ADF BC layer (and its cache). To keep the data in ADF BC entity objects identical to the changed database content a synchronization is needed. BC does not know which part of the application data has been changed because it has not initiated the changes through its entity objects. Therefore a full refresh is needed. In a Forms4GL environment the behavior is similar: We do frequently requeries of all relevant (base)tables after calling database stored logic to be sure to get the changed data to display and to operate on it.
-> Reengineering of the PL/SQL-logic to make the ADF BC layer aware of the changes is a big effort (notifying BC about any change)
2. longer living database transactions
Our PL/SQL-logic in some areas makes use of lengthy database transactions. The technical DB-transaction is similar to the UnitOfWork. If we call this existing logic from ADF BC, database state is produced which will not be DB-committed in the same cycle.
This reduces scalability of ADF BC AM pooling.
Example:
a) Call a DB-stored logic to check if some business data is consistent and prepare some data for versioning. This starts a DB-transaction but does not commit it.
b) Control is handed back to the user interface. Successful result of step a) is displayed
c) User now executes the versioning operation
d) Call another DB-stored logic to execute the versioning. DB-transaction is still open
e) Business layer commits the transaction automatically after successful finishing step d). Otherwise everything from a) to e) is rolled back.
-> redesign of this behavior (= cutting the 1to1 relation between LogicalUnitOfWork and the technicalDatabaseTransaction is a big effort due to the big amount of code.

I would like to have a password required before using Firefox as there is available with Windows Internet Explorer and Chrome.

As it is known for every one the danger of the internet for kids with out parents watching them so I need a password.

How do you require a password for IE and Chrome? (I think there is an add-on available to add this feature to Chrome.)
If you have your children sign on to Windows using their own username and password, you can easily control which programs they run: http://windows.microsoft.com/en-US/windows7/Prevent-children-from-using-specific-programs
I'm not aware of any startup password add-ons for Firefox, but there are filters available, such as [https://addons.mozilla.org/en-US/firefox/addon/foxfilter/ FoxFilter] (I haven't tried it myself).

When I print an email using firefox as my browser the print if very, very tiny. No problem using Internet Explorer. This happens with both my Gmail and my AOL emails.

My emails are printing in very tiny type (unreadable). This happens in both my Gmail and AOL email accounts. When I use internet explorer it doesn't happen. I have researched the answers online and it seems that if I go to Firefox>file>page setup>scale and set it to 100% it may fix the problem. However, I cannot figure out how to take the first step. Where can I find "file"????
Sorry to be such a dummy.

1. orange Firefox button in the upper-left corner - then click on Print - then click on Page Setup
2. if that orange Firefox button isn't showing and the Menu bar is - click to open File - then click to open Page Setup

Using an external reverb in Logic with I/O plugin

Hello,
this is my situation:
I have a Lexicon MPX500. My sound card is an Aardvark Direct Pro 24/96, which happens to have a SPDIF in and out. I believe the Aardvark is similar to the MBox, since it has a software mixer which allows you to mute and solo tracks and what not. I've connected a SPDIF cable from the in on the sound card to the out on the Lexicon (it has SPDIF in/out), and a SPDIF cable from the in on the Lexicon to the out on the sound card.
Now...in Logic...(I'm using ASIO) I have a few drum tracks that I want to send through the Lexicon back into Logic. I want to use the buss method since I only want a certain amount of reverb applied to each track. So on buss 1 I add the I/O helper plugin. I'm given the options of "Input 1-2" and "Output 1-2", so I choose these ones. I send the drum tracks to buss 1, and I hear no reverb. There is no audio being sent to the Lexicon through SPDIF. I have no idea why? I feel like I'm doing everything right. The Lexicon is all plugged in, the SPDIF cables are in the right connections, the I/O plugin is enabled...?????? Is there something I'm missing? I really want to use the buss method since I want the whole song to share the same reverb.
Thanks!

S/PDIF is probably not output 1-2 and if you don't see it I suspect it's not the intended use for them, at least on either the card or the Lexicon. I recommend you use analog outs out of your card into in/outs of your Lexicon. I bet your card sends audio out only via analog. The other possibility is to look for a setting in your card which defines the outputs and change those to S/PDIF instead of analog. I know on the MOTU I had there, but could never get it to work right.
You really wouldn't lose anything going out analog and back analog, you're only going to add a little analog quality to the verb, and that's not necessarily a bad thing.
Also using Bus only for what you want to do is not going to work, you need to also have an Aux channel because on bounce, if I recall correctly, the bus will send the signal but there is something weird about the bus and bouncing to external I/O and I think you have to bring the signal back into an aux channel and mix the verb with that. Also you need to bounce in realtime not offline.
