IMS MDrive 23 with NI RS422 Card (PXI-8431)
Hi,
I am using IMS MDrive 23 Hybrid Motor in our application. I was using IMS supplied RS422 Converter Cable MD-CC4 to commuincate with Motor from LabVIEW. With the MCode programming, I'm able to generate, download, execute and read response from motor using the IMS Converter cable. But to communicate multiple motors, we have procured NI PXI-8431 (8 Port RS422/RS485 card). When I connect the card with motor, using the IMS Terminal (Terminal utility supplied by IMS), I'm getting garbage values like > ФÈ~ > hRä~? e ÐHè~? Фè~? t ö û Þ Ý í .
I have configured Transmit/Receive Buffer and also the termination to communicate. The end application is based on LabVIEW, IMS terminal is to try viewing. Is there any difference in communicating IMS Motor with IMS RS422 Converter and other Third Party Converter?
Thanks and Regards,
Soundar.

Hi,
I've had a check to see if we have any known software conflict issues with those cards but it all seems fine, it could be that the Windows Driver layer is causing some issues. If you nip into Device Manager and go to the properties of the 8431 you should be able to change it to 2-wire mode from those settings then re-run the program.
Also does the program throw any errors at all in terms of device resources when trying to move from send to receive mode?
What versions of NI-VISA and NI-Serial do you currently have installed?
Kind Regards,

PXI-8431 not going into receive mode with VB6
I am using a PXI-1045 chassis with a PXI-8431 RS422/485 card and communicating via a VB6 program
The output of the PXI-8431 RS485 module works OK when it is in send mode, the signal levels are approx 1v and 3v for high and low, but when it is in receive mode the outputs remain at 1v and 3v instead of going into passive mode and both lines floating at approx 2v with approx 300mV differential as they should. This means when the remote devices send, the amplitude of the signal is approx half as they are competing with the PXI module, and that the centre point of the two signals are at 1v and 3v respectively. Our software does not receive the signals from the PXI module which is consistent with my theory that it is still in send mode and taking control of the lines, or maybe it has changed it to 4 wire mode.
I have swapped over the PXI card and the remote cards with our good system and the problem does not move.
I have eliminated ALL the hardware on the new ring by replacing it with a 67 Ohm resistor on the pins of a 9 way D connector plugged onto the PXI card directly. With a scope I can see that the new system is not going into passive mode, but with the same connector the old system works OK.
The only difference I can see between the 6 old rigs we have that do work and the 2 new ones that do not work is the new ones use the the NI-XNET-PXI-8513 and the old ones use the PXI_8464 CAN card. Could this software be conflicting? Is there any other updates to the NI software that could be causing it?
Solved!

How do I activate a used iPhone 3 with no SIM card for use as an ipod touch?
How do I activate a used iPhone 3G with no SIM card for use like an iPod Touch? It was apparently on AT&T previously and I have another iPhone 3 that is active on AT&T if that is helpful. Thanks!
Copied from the link provided.
Follow these steps to use your iPhone without a wireless service plan:
Insert the SIM card from your new, activated iPhone or one that was previously used to activate the original iPhone.
Connect the iPhone to iTunes on a computer connected to the Internet.
Once iTunes activates the device, you're free to use the iPhone as if it were an iPod touch. -
Dear sir
I bought my iPhone 4 from Apple store in Charlotte N/C about 2years ago without contract.
Now I tried to upgrade it to iOS 7.0.4.but after that my phone not work with last sim card.
And invalid sim appeared.so I bought it without contract but it seems to be lock in my country
Please tell me whats the matter?
My phone serial no 86034HTCA4T
Modem firmware 04.12.09
ThanksWithout contract is not the same as unlocked. The update to iOS 7 relocked
the iPhone to the wireless carrier to which it was originally locked. You must
contact that wireless carrier to see if they offer unlocking and if you qualify.
If you used jailbreak or other hack to unlock the iPhone initially, the method
used may prevent a legitimate unlock from succeeding and may render your
iPhone unuseable. -
Hello,
I have an iPhone 4S 32Gb White AT&T, product part No. MC921LL/A, Serial No. C39GMLPWDTDC
I bought this iPhone from Apple Retail Store (from Fifth Avenue, NY) for the full amount. Now it does not work with my SIM card only works with AT&T. I restored the phone several times, but I have not received "Congratulations your iPhone has been unlocked". Please activate my iPhone to work with different SIM cards
Thanks,
Best WishesWhen did you buy it?
Apple did not begin selling an unlocked version of the iPhone 4S in the US until 11/11/11. I believe it went on sale only through the online store at that time. I'm not sure if it's available at retail yet.
What you purchased was a phone without a contract commitment. It is still locked to AT&T. AT&T will NOT unlock iPhones for any reason. Return it and get your money back, then use that to purchase an unlocked phone. -

Help with Airport Extream Card in PowerMac G5
Hello,
I have purchased a used Power Mac G5 with the following hardware:
Model Name: Power Mac G5
Model Identifier: PowerMac7,3
Processor Name: PowerPC G5 (3.0)
Processor Speed: 2.5 GHz
Number Of CPUs: 2
L2 Cache (per CPU): 512 KB
Memory: 2.5 GB
Bus Speed: 1.25 GHz
Boot ROM Version: 5.1.8f7
While it works perfectly, the machine didn't come with an airport card which I installed:
Wireless Card Type: AirPort Extreme (0x14E4, 0x4E)
Wireless Card Locale: USA
Wireless Card Firmware Version: Broadcom BCM43xx 1.0 (4.170.25.8)
The machine appears to recognize the airport card and I can "see" my home network but can not connect to it. When I enter the WEP password, it just fails to connect. I have 2 other macs in the house (and an iPhone) along with an HP windows laptop that connect to this network without issue, so I am confused.
I think there are (at least) 2 variables that I am unsure of:
One: Do I have the right airport card? As best I can tell, I do. But if anyone can tell from the hardware info I copied above, I'd welcome any info. I did see some posts about "late model dual core" G5s (labeled as model 10,x in system profiler) that needed a different card. I took the airport extreme card from one of my other macs (G4 Mirror Door) and the card works perfectly in that machine. I THINK it's the right card for the G5, but can't be sure.
Two: Do I have to install any software to configure the card on the computer.
What else should I be looking for?
Many thanks,
SteveHi-
The Airport Extreme card for the MDD FW800 model is the same as in the G5 up to Early 2005.

Did you connect the antenna to the card correctly?

Did you connect the external antenna (T shaped, plug in rear of tower)?

After proper installation, it should just be a matter of making adjustments to your network settings. -
I can't seem to update my apps or make any purchases on from my account. Nothing has changed with my credit card information and for some reason the iTunes Store tells me my information is incorrect. What do I do?
Yes, it's frustrating.
I don't have my iPod with me but, as I recall, the change is done in Settings/Store. That change will apply to NEW purchases. However, be aware that all purchases are permanently associated with the Apple ID that was originally used. Generally, it's only a problem when you need to update an app. IF you do your updating from iTunes and your logged in to the "wrong" ID, you'll need to log out and back in again. It's easier from the iPod as you do not need to log out/in but you do need to know the password.
Unfortunately, you can not merge IDs nor can you transfer purchases from one ID to another. Go here to find out exactly what you have. I have the same problem so I deliberately made both passwords identical to make things slightly easier for me. -
My iPod Touch battery is not working. I requested a repair through the Apple Support. On the final page, when I clicked the button that puts the info through with your credit card number, the resulting page gave an error (I wish I'd have saved it!). Anyhow, I checked my credit card and it was charged, so I assumed the repair request went through. The next day I received a form email saying my problem was with "Sync with iTunes (Not iCloud) - Data Backup/Migration (not iCloud)" instead of the battery repair. It also says for iPod customers, to send your iPod to Apple - but I had requested the "iPod Coffin" to be mailed to me so I could send it back. Obviously there was an error between the request and what was received, so I'd like to ask Customer Service about it. However, I can't find a way to contact them. When I replied to that form email, I recieved an automated reply saying emails there were not read. Anything online asks me to pay $19 and I don't have the correct issues to request an exception. The closest store is over an hour away or I'd simply go there to ask. What can I do?! Any suggestions you have are much appreciated. Thank you!
PS - The form email also says if I wait 10 days the repair request will be canceled. Does this mean my credit card will be refunded for the $85 battery replacement charge if it is canceled automatically?Thanks, but I've been on the phone with AppleCare US (where I am and live) and AppleCare UK. They continue bouncing me back and forth without helping resolve the problem.
Perhaps someones knows how to further escalate the issue at Apple? -
Hi, i am going to buy and iPhone 5 in france but it says its an unlocked iphone so i guess if i take it to Ecuador (my country) the iPhone is gonna work with a sim card from Ecuador right¿
If the receipt says "unlocked" (and not "SIM free") then it will work anywhere in the world that there is a GSM network. However, if it ever needs repair you will have to take it back to France.

I made a purchase with my debit card on The Simpson Tapped out game, And now my game won't open. It just kicks me out every time I click on it. How do I fix this problem with out deleting my app?
Personally, I would never use a debit card online, for security reasons. If your card gets hacked its your money that is stolen. At least with a credit card it is the card providers money that is stolen.
Anyway, I would delete the app and re-install. If you paid for the app in the first place you will be able to re-install free of charge. Also, the app should allow the in-app purchase to happen again as it should recognise that you have already purchased it previously.
Finally, it might be that the 3G doesnt have as much ram as more recent models of iphone and you may have applications running in the background that are preventing the app to function with the in-app purchase unless you shut down any apps eating all you memory that are running in the background. Shut-down these apps (and the simpson tap out app) by exiting to your home screen and double-tapping the home button to show what apps are running in the background. press and hold any of the open apps until it starts shaking. close all the apps down. exit then re-launch the app.
good luck. -
How do I delete a credit card from my iTunes account without adding another one? My friend bought an app with her credit card and I no longer have the info but every time I try to download a free app (ex: Instagram, Twitter, vine etc.) it ask for the credit cards security code. I can not find a way to delete that cards info without adding another cards info.

I let my grandsn open and itunes account with my credit card. I want to remove my cc# from his account. I do not know his apple id or password. How do I proceed?
I would say let him fess up and give him a chance to mend his ways, but there is at least one app that goes for $900 (according to another poster's request for a refund). You may end up $1000+ deeper gone.
Change the account number which will close the current links and freeze/prevent charges under the old number. As I understand it Apple gets grumpy when charges get rejected, and you need to jump through hoops to get a payment method reattached.
Yes this is a grumpy answer. -
I bought an iPad and an iTunes card, I want to buy an application from the Apps store but it only gives me the option of credit card. How can I buy Pages with my iTunes card to my iPad? thank you
Have you redeemed your iTunes card to an account associated with an Apple ID?
Once you have your iPad associated with an Apple ID AND you have an account with a credit card associated with the same Apple ID AND you have some 'store credit' (from redeeming your iTunes card) then purchases use the store credit before they charge the credit card, so you should be ok!
Personally, I use 'store credit' as a way to monitor whether or not there have been any 'unauthorised' purchases because as soon as the store credit is zero, the security code from the credit card is needed for further purchases! It does mean that I have sometimes to top up store credit before making a purchase, but 'better safe than sorry'!

Re: Do i need to turn off home sharing before syncing to iTunes
