How can i messure temp on 2 diff channels simultaneous on a USB-9161 Carrier ?
Hello, I was wondering if u can help me with a small problem, with my USB-9161 Carrier. I intend to messure temperature with two thermocouples on 2 physical channels of the device, in the same time. Do i need a special VI for this operation ? As far as I have seen the VI promps me to select a single phisical channel. Can I record data for both thermocouples? Thank you so much
Hi Tzaca,
Can you clarify which module you are using within your 9161 Carrier. The 9161 does not contain any data acquisition functionality by itself but enables certain C-Series modules to interface with your PC via USB. For Thermocouple measurements the ideal module would be the NI 9211 for your purpose, however other modules will work that contain the appropriate signal conditioning. I.e. Cold Junction Compensation (CJC).
Assuming you have an appropriate module however you can record from both thermocouples using a LABview programming technique called synchronization. I have found an article on the NI Developer Zone website that explains this principle well using LabVIEW 2010. Take a look at this and see how you get on.

If you need any more assistance with this let me know how you get on and I'll try and help you further.

How can I separate Left and right audio channels in labview 8.5 tia sal22
How can I separate Left and right audio channels in labview
8.5 tia sal22
Greetings All
I have a working Labview vi that converts a math formula to an
audio signal. I would like to have the
right and left audio channels playing different math audio signals is this
possible?
Example
Right channel -> plays the audio signal created by a math
formula
Left channel -> plays the audio signal created by another
math formula with adjustable phase control
I’ve included a VI with a working audio and math formula but
I’m not sure how to separate the left and right channels.
I’m using labview 8.5
I looked up a similar question on the
support board and it said” use an instance of the the Sound Output Write that
has a 1D waveform data type input (i.e. Sound Output Write (DBL)). Each
element in the array would correspond to a channel.”
But I’m not exactly sure what he meant. I’m using a formula to generate the wave file

I'm using a Gigaport HD 8 output usb audio device but I'm experience clicks and pops. I increase the buffers
but I still get the clicks and pops. I know gigaport HD can use ASIO drivers which most likely would solve the problem but one needs to code in C for this which I'm not proficient in. Can someone recommend a work around to prevent this clicks and pops, can I somehow change my VI to fix this? Does anyone have a VI that will allow access to the ASIO latency properties?
I'm using labview 8.5
And a gigaport HD which is a USB audio device which outputs 8 analog signals (it is ASIO compatible)

How can i connect FP-PWM-520 8-Channel, 5 or 24 V PWM to computer
Hi
How can i connect FP-PWM-520 8-Channel, 5 or 24 V PWM to computer.
Is it supports for Programmble interface(specially using LABVIEW).
Give me the details to interface connector hardware and software description.
Thankq all
Mahesh.Hi Mahesh,
It sounds like you are just getting started with using the FP-PWM-520.
Since you are looking for rather general information I would recommend that you search ni.com for 'FP-PWM-520' and you should find plenty of relevant links.
Connection info can be found in the Operating Instructions Manual which is linked off of the Product Page. More general information can be found on the DataSheet.
As with all other National Instruments products you can easily program
and control FieldPoint from LabVIEW. Don't forget to download the
latest version of FieldPoint (currently NI-FieldPoint Version 4.1 for Windows 2000/XP).
These links and any other searches should help you find what you are looking for.

How can I get music from two diff devices onto my phone if it's only synced to one?
I have a desktop an laptop both windows with iTunes on both with same Apple ID. Both have diff music on each But the laptop is sync to my iphone & when I have tried to sync my I phone to my desktop it wiped my music. How can I combine music from my desktop and laptop into my iphone without wiping what's already on there?
Welcome to the Apple Community.
Assuming it isn't purchased content from the iTunes Store, then your only way is to put all the music onto one computer and sync with that. -
How can I get my old iPhone 5 (Verizon) unlocked for use with another carrier?
I have an iPhone 5 that was purchased with a Verizon Wireless account. It is more than two years old and I have since upgraded it to a newer iPhone. I want to give this phone to a friend in Germany. His service will provide a new sim, if the phone is unlocked. How can I get it unlocked so that it is no longer limited only to Verizon Wireless?
Good afternoon Weth! That is completely correct. All 4G phones are already unlocked for global use. If you contact your international carrier and insert their sim card, it will be ready to activate on the international network. If you have any questions regarding the compatibility of the international network, please reach out to them directly. If you have any further questions, please let us know. Thanks so much and safe travels to you!

Yes, new web-developer all-in-one tools are total mess.
I didn't find the answer to this question either https://support.mozilla.org/en-US/questions/955612 but downgrade to Firefox 19.
But nor in Nightly, nor in Aurora, nor in Firefox Beta, nor in Firefox 20.0 I can use simultaneously web-console (where I test some style changing javascript code) and element inspector (where I instantly observe a reaction to my code). The only option I see is to switch every three seconds between them. How can I fix this except downgrading?You can consider to use the DOM Inspector extension instead of the built-in Inspector.

You need to contact Sprint to unlock a device locked to them. As far as using internationally, talk to Sprint about your options as well.

i have bought iphone 5s from usa its carrier is sprint..how can i unlock or what shouid i do to unlock it?
You will have to contact Sprint in the USA about that - only the carrier it is locked to can authorize an unlock. BTW, Sprint will not unlock it if you are not a Sprint customer.

How can I record two instances of Addictive Drums simultaneously?
Hi, I'm having no luck with something I thought would be simple. I want to run and record two iterations of XLN Addictive Drums in two separate tracks simultaneously in Garage Band X. I play a Yamaha DTXtreme IIIs e-kit as the MIDI trigger. Because Addictive drums doesn't have enough "openings" in a single kit to accomodate all my cymbals, I want to run two iterations with the extra cymbals on an iteration. Unfortunately, no matter what I try, I can't get both tracks to record simultaneously, even though I enabled multi-track recording and armed both tracks. Help?
flagg1337 wrote:

unfortunately, while GB can record many audio tracks, it is restricted to a single MIDI track at a time.
fortunately, GB offers "Cycle Recording," perhaps that will work for what you're attempting
turn it on in GB's prefs, turn on the Cycle Region button and hit record. each pass will merge with the previous one, so you could, for example, play kick, wait till the next pass to play the snare, etc -
How to transmit counter input data of different channels simultaneously?
Hello.
I'm using X-series PCIe-6361 DAQ board which have 8 DMA channels and Labview 8.2.1. I upgraded the version of DAQmx as 9.0 which supports the X-series devices and confirmed the board worked normally on my system.
I'm trying to measure the pulse width continuously from 4 different pulse trains with CMOS level. The frequencies of signals are same but the pulse width and phase are varying with respect to time.
http://zone.ni.com/devzone/cda/tut/p/id/9376
From the tutorial page of NI X-series, I saw the following expression "X Series also includes eight DMA channels to stream data directly
between the device and PC memory without CPU interaction or additional
programming effort. These eight channels provide parallel data streams for the analog I/O, digital I/O, and all four counter/timers."
But when I started the Labview programming, I realized that the counter functions of different channel cannot be put into a single task. So I couldn't help but separate the read functions into 4 individual tasks and there are timing differences in data transmission between channels up to 250 micro-sec because of the sequential running.
How can I eliminate the timing difference and realize parallel data streams for the counter?Check out these links. I hope that they help!
