Synchronization features 2 usb-6009 - please help
Hello
I'm trying to simultaneously capture data from 2 devices usb-6009. I've implemented the two Renault as follows.
1. using a function generator, generate a sine wave, which is slower and not a multiple of the sampling notes (48 kHz) and apply it on the odd numbered tracks.
2. connect the pairs of channels on the ground.
3. connect the PFI0 to a digital output of one of the Renault.
4. implement each DAQ sample faster (48 kHz) as possible and trigger off the coast of PFI0 entry.
5 generate the shutter of digital output - software write to 'Dev1/port0.
6. read samples that result and determine the difference between each of the odd channels between the Renault in a given set sample.
My results are not as expected. Use Excel to plot the data, I see that the Renault 2 data are staggered on each set of sampling.
I checked on the scope that the trigger works and that both got triggered. I think that the configuration above is not complete and I think I need to
Configure the two Renault to share the same clock source, but I don't know how to set up 2 Renault to share the same clock. My questions are
(1) exceeds my setup ok?
(2) If you need to configure 2 Renault share the same clock, how to put in place?
(3) is it possible sync 2 devices usb-6009?
Thank you

Your above configuration seems correct.
The method that you use to synchronize two devices is the best you can get. The PFI line can only read in a trigger or a counter of entry. You cannot use to import a sample clock. Each 6009 must use its own on-board clock.
Typically, if you really want to sinchronize both acquisitions you must share a sampling and a trigger to start clock. Here, we are only able to share a departure with the PFI line trigger (such as material prevents you from sharing the clock) and let the individual clocks govern the actual acquisition is simply not possible really to synchronize two 6009 s and you're doing the best you can.

How to synchronize clocks on USB-6009 and USB-6343
Hello
Can anyone provide an example on how to synchronize clocks on USB-6009 and USB 6343?
I checked the example screws, but it shows that we must use 2 counters, one as the clock of the source and the other as a trigger. But only 1 CLK 6009.
I read the user manual and it is mentioned to use (AI/start-trigger) in order to use PFI0 as source.i am somehow confused about how to achieve this.
Furthermore, what would be the physical connections?
Thank you

Unfortunately, you won't be able to completely synchronize your devices USB-6009 and USB-6343. As you have seen, the 6009 has only a meter on board.
You can certainly use PFI0 as an input to start your tasks at the same time digital release. However, the 6009 is a strictly timed by the software. There is no way to import an external sample clock.

I have Windows 8 is installed and an iso of Windows 8.1 on my USB.
My previous version of windows (which is already installed on the hard drive) will erase if I boot from a bootable USB. Please help me!
When you upgrade to 8.1 Windows it will replace your Windows 8.0. The only way I know to have both is to buy a copy of Windows 8.1 and install on another partition or drive. Hope this helps and if you need another post to help and we will be happy to help you.

Hi cowmanchess,
It seems that you are having problems with your USB port on the computer.
Have you tried using a different USB port on the computer?
Have you tried a new USB cable?
How long is the USB cable you are using?
You have a USB hub between the printer and the computer?
Unplug the USB cable and then download the software on the link below. Wait that the installation of the software requires you to connect the cable. Let me know if you get the printer installed?

Can I synchronize and AI on USB-6009 with meter?
Hi all
I use USB-6009, LV 8.5 under windows XP. I want to generate signals synchronized with Amnesty International. I know that I can not use the sample as DO clock clock. But can I use the card counter to synchronize and AI? And can someone give some similar examples? Thank you!
Best wishes
Bo
The unit will display whenever you call writing DAQmx. It is more complicated than that. And synchronization is practically based on the flow of data and when you want to generate the digital output from the analog input.

All the Windows drivers for your laptop are on Portal support business web users for your laptop HP. In the drop-down list, select Windows XP. It's an operating system supported so reinstall drivers.
Check the Basic Input/Output System (BIOS) for Legacy USB Support. To do this, follow the procedures below:

my USB cannot be recognized by any computer please help me. Thank you.
my USB cannot be recognized by any computer please help me. Thank you.
Then, it probably doesn't and therefore more recoverable. If several computers say it cannot be read, or it must be formatted before it can be used, then the problem is the flash player. It does not, or the files that it contains are corrupt. I hope that you have a backup of them stored somewhere.

You must have installed a Windows 7 64-bit driver (if it exists)
for this. Do you have? Otherwise, navigate to the web site of the camera
manufacturer, search, download and install it.Ken Blake, Microsoft MVP
