Why i not has two analog outputs at same time ?

Hi, i am try to output two analog signal, which is trangle and sine waveform, with my pci 6036E. i code with Labview 7.1 and the vi is in single loop with both triangle and sine wave analog output to AO0 and AO1.
someguy can help me to figure out is there any problem in my vi or is there any other way.
thank you very much in advance.

Hi All-
Dennis is exactly correct- only a single analog output (or input) task may be run at once on any DAQ board. To add one small bit of advice, CUHK, you will also need to choose the correct polymorphic instance of DAQmx Write to reflect "N Chan N Samples" as shown here:
You will also need to build an array of waveforms using the Build Array function. Hopefully this helps-

Acrobat xi pro will not open two documents at the same time

Hello...
I recently upgraded to Acrobat XI Pro and now when I try to open more than one document, the second one turns into a parallelogram and does not open. The only thing that I can do is close everything out and reopen the documents one at a time.
Does anyone have any suggestions.
I have tried to reinstall and repair, both to no avail.
I am using this on a Windows 7 machine 6GB ram.
Thank you

Please explain "turns into a parallelogram and will not open". Can't visualise that at all, please explain. A screen shot might be good (but DO NOT EMAIL IT).

How to synchronize two analog output with USB-6353 sharing a trigger

I'm have the need to synchronize two analog output on the same device (USB 6353) sharing a trigger signal on PFI0.
The programming environement is Visual C++ , and the code I wrote is as following:
DAQmxCreateTask ("", &Ao0TaskHandle); // is the task handle for the analog output Ao0
DAQmxCreateVoltageChan((Ao0taskHandle,"Dev1/Ao0","",-5.0,5.0,DAQmx_Val_Volts,NULL);
DAQmxCfgSampClkTiming(Ao0taskHandle,5000.0,DAQmx_Val_Rising,DAQmx_Val_ContSamps,1000);
DAQmxCfgDigEdgeStartTrig(Ao0taskHandle,"/Dev1/PFI0",DAQmx_Val_Rising);
DAQmxCreateTask ("", &Ao1TaskHandle); // is the task handle for the analog output Ao1
DAQmxCreateVoltageChan((Ao1taskHandle,"Dev1/Ao1","",-5.0,5.0,DAQmx_Val_Volts,NULL);
DAQmxCfgSampClkTiming(Ao1taskHandle,5000.0,DAQmx_Val_Rising,DAQmx_Val_ContSamps,1000);
DAQmxCfgDigEdgeStartTrig(Ao1taskHandle,"/Dev1/PFI0",DAQmx_Val_Rising);
DAQmxWriteAnalgF64(Ao0taskHandle,1000,FALSE,10.0,DAQmx_Val_GroupByChannel,AOdata,NULL,NULL); AOdata is a buffer containing a sinwave
DAQmxWriteAnalgF64(Ao1taskHandle,1000,FALSE,10.0,DAQmx_Val_GroupByChannel,AOdata,NULL,NULL);
DAQmxStartTask(Ao0taskHandle);
DAQmxStartTask(Ao1taskHandle);
What happen as result of the code is that only the Ao0 channel get the sinwave output , but not the Ao1 . It seems the two channels are not synchronized.
What is wrong in my code?
Please any help non referred to a LabView soloution , first because I'm not a LavView programmder and secondly the project impose C++ as the unique environement.
Thanks

It will depend on what you are programming the NI 5112 device with.
If you are using LabVIEW, you can use the example program attached below. In it, it will show you how this is done.
If you are using VB, VC++ or CVI, you can look at one of the NI 5112 shipping examples that are installed on your computer. These are located in the VXIPNP folder. For example, the VC++ example would be located here:
C:\VXIpnp\WinNT\NISCOPE\Examples\c\MStudioC++\5112Sync
These examples will show you how to synchronize the two digitizers.
Let me know if you have any questions about these examples.

I want to have two different operations on two analog output terminals of DAQ. When I work

with AO0, it works. But after I add in another channel, AO1, there is an error saying that 'specified group is in use'.

Doug is correct. Both analog outputs have a shared clock. If you want to write to both outputs simultaneously, you will need to include both of them in the same operation (group).
You can write a 2-D array to the AO Write VI in which you can include data for both channels. In the 2-D array, column 1 will be for the first channel in the channel list and column 2 will be for the second channel.
I hope this helps.

E3631A IVI class driver can not enable power supply three channel outputs at same time

Hallo,
with E3631A IVI class driver i am trying to enable all the channels at the same time,The problem is that class driver supports only Channel Switching between three Channel,i find in this Forums this Discussion
http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/E3631A-IVI-class-driver-cannot-enable-power-s...
is it possible to enable all outputs at same time that I modify the source code and recompile the drivers,but it is complicated for me.
Is there a another easy way to solve this problem??
Would appreciate if someone who has worked on it suggest a method appropriately. Thanks!
Note：Labview 2009 sp1

You'll either have to modify yourself, ask the poster in that other thread for it, or use the LabVIEW driver.

I AM TRYING TO HOOK UP TWO MONITORS AT THE SAME TIME

I AM TRYING TO HOOK UP TWO MONITORS AT THE SAME TIME. I have had no success in figuring out why I can get an image on my TV and an image on my monitor (at the same time), but no icons, no start menu and no keyboard access. M y computer freezes as well when I try to do 2 monitors.

Hi,
Your machine has:
*Integrated video is not available if a graphics card is installed.
Radeon HD 6370D, 6410D, 6530D or 6550D Graphics (model dependent based on processor)
Supports PCI Express x16 graphics cards
Two DVI-D ports (Both ports can be used at the same time)
You can use TWO monitors with the right connections for two ports #3 above. You can get more information from the following instructions:

Can't start two listeners at the same time

Hello -
I am running Oracle 10g R2 on Solaris 10. I am getting the following error when I try to start my second listener "TNS-01106: Listener using listener name ccn_listener has already been started". There are multiple VIPA's assigned to the server, so I am trying to start two listeners at the same time (I can start each one separately). The different IP's are referenced in the listeners (even though they use port 1521), so there should not be a conflict. I also gave the two listeners distinct non-default names. The listeners are running under two differenct Oracle homes.
Here is the code of the listeners:
listener 1:
PHD_LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.49.236.119)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
SID_LIST_PHD_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u02/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME=phdv410g)
(ORACLE_HOME = /u02/app/oracle/product/10.2.0/db_1)
(SID_NAME = phdv410g)
listener 2:
CCN_LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.49.236.131)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
SID_LIST_CCN_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME=ccn10gt1)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(SID_NAME = ccn10gt1)
If anyone has any ideas about why I can't start these two listeners togethers, I would really appreciate it.
Thanks!

Hi,
Look at the error: "Listener already started"...
Can you check if that is right ?

Dual Audio Outs? / HDMI and RCA Analog at the same time?

I am trying to figure out if the Apple TV supports dual audio output. My Onkyo receiver supports dual-room/dual-source audio (powered and line-level stereo audio output for 2nd room). The problem is it can only accept an analog source for the second room.
I know that HDMI takes precedence over component video connections if both are connected.
Will the ATV send audio signal out of the HDMI and RCA Analog jacks at the same time so I can enjoy streaming music is two rooms simultaneously?

Iowabeerguy wrote:
I like to be a helpful soul, so I decided to pull the owner's manual from Onkyo and take a look at the receiver, without ever thinking about the model number, and come to find out, I have my Apple TV hooked into an Onkyo TX-SR606.
I appreciate that!
Iowabeerguy wrote:
Problem is, I have the HDMI into the Onkyo and the analog outs going to to another stereo receiver for the outdoor speakers. Both work at the same time, which means that the Apple TV will output both digital and analog at the same time.
Good to know.
Iowabeerguy wrote:
Now, let's look at the receiver - if you have the HDMI plugged into the - say DVD input, and it's playing through the main system, and you plug the analog outputs into the DVD analog in on the receiver, the Zone 2 out will automatically look at the HDMI input, and not put out anything to the Zone 2 outs, because it won't pass digital to the Zone 2 outs.
Oh yeah, that makes sense!
Iowabeerguy wrote:
I can't try it tonight, but I think if you plug the analog outputs from the Apple TV to an input that isn't assigned to an HDMI in, (like CD) and then set the Zone 2 amp to play that source, it should work.
I've set aside some "tinkering" time this weekend to try that. I'll let you know if it works; I think it will. Thanks again!

Re: if weblogic can serve two ports at the same time?

That's not true. WebLogic supports a non-secure and secure listener port at the
same time. That was one of the selling points for my organization.

Well, the question was really meant to see if any change was made to WL to support

Why do they 'have to be on different ports'? We block requests by URI
- so just
block all requests to /youradminapp/* at the firewall. Or you can block
them at
your Web Server. Or restrict them by user in WL.

Write a progarm to test two parts at the same time

Hi:
I need to write a program in LabView that is capable of testing two parts at the same time.
Explanation:
I star the test on a unit, once all the electrical test is done move that unit to the pressure test without loosing the current test information and continue the test of the unit thewn generate a serial number only if it passes all the test. Then while the previous unit is going thru the pressure test star testing another unit for the elecrical test and so on.
I am using LabView 2012

One again, "can I use CC on two computers at the same time?" - in practice.

I know this has been asked before and all those threads are locked. Many asked the question, but I haven't found a satisfying answer yet.
Can I multi task with CC?
I want to have my laptop next to my desktop. And while I render, export or whatever my newly shot documentary on the laptop I want to work with a music video project on my desktop. Then when the render is finished I render the music video and go back to the laptop and continue on the documentary. Or maybe I just work 5 minutes on the desktop music video, then come up with something brilliant for the project on the laptop and switch. Back and forth. Will that kind of activity result in any kind of limitation, usage-wise?
So, working on Premiere on my two computers at the same time.. is it possible? Technically? I know the EULA says "only one person". But will it let one person mutli task?
I need to know this before I buy. sorry for asking this again, please bless me with a clear answer

Hi Jimmy Crim,
Yes in case of Creative cloud subscription you are allowed to install and use the cc apps in any two machines.
Even if you want you care allowed to use these apps together in both the machines.

How can I open two libraries at the same time on itunes?

Hey i need help on opening two libraries at the same time on itunes. I don't know if that is possible but need some advice if its possible. I already have several libaries but I need to compare labaries at times due to various users on my computer. Please help .

Not that I'm aware of. What exactly is that you want to achieve? There are tools for scanning media folders and adding any files not listed in the library, or deleting those that no longer exist. There are also ways to use one library for multiple users so that any tag update gets applied for everyone.

How can I start two Vi at the same time?

I have two Vi's, each of these Vi has a stop button. I want to start these two Vis at the same time. I also want to be able to stop the two Vis at the same time. What should I do? Thanks.

One way to start them is with an Invoke Node and the Run method. You can then stop them with the Set Control Value [Variant] method. When you use the Set Control Value [Variant], you just have to specify the name of the front panel control that stops the while loop. Older versions of LabVIEW only had the Set Control Value method in which you had to use the flatten to string function to pass the Type Descriptor and Flattened Data.

How can I compare more than two VIs at a same time in labview 2009

How can I compare more than two VIs at the same time. I am an Lab Engineer I have to check assignments submitted by students and I want to know how many of them are copied from each other. Labview compare VI can only compare two VI at a time while I want to check about 30 VIs at same time.
Regards,

I'm not aware of a tool to compare multiple VIs. If you don't find anything, consider posting this to the LabVIEW Idea Exchange to expose this idea directly to NI R&D.
Thanks!
