Hi!!I want to scale an analogic signal, and I don´t understand very well how interpolated option works in "Scaling and Mapping".
Can anyone explain to me, the option Interpolated, in the function , "Scaling and Mapping?
Thank you!!!!!
When you select Interpolation you then define a table of value pairs; basically the raw data versus actual data.
For example
2 5
4 10
6 20
What the VI then does is if the input signal has a value of 3 the Express VI will linearly interpolate between 5 and 10 and will map your value of 3 to 7.5. Again a value of 5 would then be interpolated and mapped to 15.
Take a look at the attached VI.

I won Lightroom 1.0 as a door prize a few years ago at an Adobe clinic in Fremont. I have since misplaced the original disk and cannot get the program to open. It wants a serial number and I don't have one. How can I get the serial number so I can use the software?
Thanks for replying, Jim. I wasn't planning to use it for raw images. I shoot film, black and white, and have many negatives I want to print. I am unfamiliar with the upgrades in Lightroom. I wasn't unhappy with the version I have. It was useful for my purposes.
Because it was a few years ago, I don't remember if I registered the product. I was able to login to my account. But could not find a path to communicate with Adobe. I will keep trying.

My husband has a iphone 4 8Gb, now i have one to. We want to manage our calendar with icloud. We use the apple id that my husband made, but i want to play in the game center with my one name and games. How can i do that?
Sounds like you encrypted your iPhone backup, & if so it's asking for the encrypted backup password. Do you have a company Exchange account on your phone?

Thanks for any help with my apple id delima.
You can set up an iCloud account which makes the iCloud email address you choose the Apple ID and thus the login for it:
https://discussions.apple.com/message/22283348#22283348
though I have to say I think it's more sensible if the ID is another address, both for security reasons (so people don't know what the login is) and as a contact address from Apple if the account were to stop working and they needed to contact you. So personally I would to to System Preferences, enter the GMail address which is an ID, and then choose a nerw @icloud.com address.
If she has her own iCloud account she will need either her own computer or her own user account on your Mac to be able to make use of it. You should note that under Apple's terms of use Apple IDs are only available to children of 13 and over.
As to purchasing apps, this is nothing to do with iCloud: it's iTunes, and the login can be different. So you can all sign into the same iTunes account but have different iCloud accounts. Or she can have her own iTunes account if she is of suitable age (credit card needed for purchasing apps).
If you have other children you should be aware that any one Mac or device can create only three iCloud accounts - this is tied to the serial number, not the user account, and once reached cannot be bypassed. You can of course sign into an iCloud account created on another device. -

I cant seem to import the present songs, photos etc on my phone so that I can restore. I have software problems. Why can't I transfer my photos to my new mac computer?
" Why can't I transfer my photos to my new mac computer?"
What photos? You can import camera roll photos ( taken with the iphone) as you would any other digital camera.
Photo library pics are synced one way only. As they came from your computer in the first place, they should still be there and included in your regular backup of your computer. Copy them from the old computer to the new one.
The music sync is one way as well. The only exception is itunes purchases. Without syncing: File>Transfer Purchases
You should copy everything from your old computer, or your backup copy of your old computer to the new one. -
Please help I Tried everything but nothing worked..
Errors 3000-3999 (3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the update server (gs.apple.com) on ports 80 or 443.
Update to the latest version of iTunes.
Verify the computer's date and time are accurate.
Check that your security or firewall software is not interfering with ports 80 or 443, or with the server gs.apple.com.
Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.
An entry in your hosts file may be redirecting requests to gs.apple.com (see "Unable to contact the iOS software update server gs.apple.com" above).
Internet proxy settings can cause this issue. If you are using a proxy, try without using one.
Test restoring while connected to a known-good network. -
How to acquire analog signal and send a TTL pulse at the same time based on PXI 6123
Hi,
I am using a PXI-6123 data acquisition card, as the picture show in the attachment ,I want to acquire the analog signal of ai0 through reference analog window and at the same time send a TTL signal to trigger my camera. I have tried two methods, one is using the DAQmx Export signal.vi another is using DAQmx connect terminals, but when the data acquisition card acquire the analog signal, the DAQmx Export signal.vi and the DAQmx connect terminals sometime can send an TTL pulse ,sometime can not.
I don’t know why? or some other method that can achieve my arm is appreciated.
Regards

Send a TTL pulse.JPG 288 KBHi,
Have things changed over the years?
I need to syncronise a digital output (Modul NI9474) and an analoge input (AI-Modul NI9203) module. I need to measure time intervals from a flank in signal A to a flank in signal B. I would like accuracies of the order of 1 ms. Currently, the signals are not synchronised, with errors of the order of 2 times the block length (block size x sample rate), sometimes much higher. The best I got so far was a block size of around 20 with a sample rate of 1 kHz.
If I use the master and slave settings on the RTSL settings, my program doesn't run properly.
If I use digital signals for input and output, I can syncronise them with RTSL settings and everything is good, but I can't always do that.
Also, if I do anything in the GUI (such as scrollowing something or going to another window), my output gets screwed up properly.
1. What can be done to synchronise AI with DO?
2. Is there something that can be done to avoid messing up the output when something happens in the user interface? (I know that I am messing up the outputs as they make some valves switch and that is loud).
Thanks in advance! -
Analog signal to Zone 2 speakers?
Hi Guys. I want to send an analog signal from Apple TV2 to my zone 2 speakers on my Onkyo AV Receiver but it will only take analog RCAs. Is there a converter or something I can use? Thanks in advance.

Convert analog signals into I2C
hi all,
I am using NI-6351 DAQ unit.I want to capture two analog signal and I2S data from the hardware.
Is it possible to do this?Depends upon what computer you have. You'll need a player with an output line of some sort, then a converter to go from analog to digital (e.g. http://store.griffintechnology.com/catalogsearch/result/?q=imic). then recording software (free Audacity). Time.
Those are the basics. For higher quality you might want a soundcard that has RCA input and various software packages for cleaning up the audio.
How may cassettes? it may be cheaper to just buy the CD. There are also commercial services that will transfer cassettes. If you're just talking one or two I would go that route because you can spend a lot of time doing this and that will increase sharply if you haven't done this kind of thing before. -
How do i send an analog signal to trigger another program
I am trying to send out an analog signal from labView that will start Bioware. How can I do this?
Hi Orbz,
There are 3 Send modes in Logic:
• Pre Fader (original signal is sent before it reaches the channel strip's fader etc.
• Post Fader (sent before volume fader adjustments)
• Post Pan (send before volume fader and Pan/Balance adjustments).
Click and hold on the Send slot in your synth channel strip and select Post Pan fro the drop-down menu.
Funnily enough I've just finished writing a tutorial about this very topic!! It's not published yet, but will appear on the macProVideo.com blog in the coming days...
