hi to all,
i seen that all other competitor is also having 32 digital I/O high speed data acquisition card. can any one let me know how PCI 6534 differs from adlink or any other make HSDIO card..
also i am intersted to know the onboard memory and pulse width detection specs. what is the importance of these two specs in real world?..
please let me know the with details so i can purchase the right oone...thank you

Under the following link you will find all the necessary resources for the 6534 -> http://sine.ni.com/nips/nisearchservlet?nistype=psrelcon&nid=3530&lang=D&q=FQL:%28locale%3Ade+OR+locale%3Aen%29+AND+%28phwebnt%3A929%29+AND+%28nicontenttype%3Aproductmanual%29+AND+%28docstatus%3Acurrent%29%20RANK%20nilangs:de&title=NI+PXI-6534+Handb%C3%BCcher+%28engl.%29
However I would suggest to call your local NI office to talke to a sales representive who can give you the best help in this case!

You must not have read the datasheet which describes the advantages of a large amount of on-board memory.
If by pulse width, you mean the 10ns minimum for triggering, the importance of that would depend on the data you are trying to capture. If your trigger signal has a pulse width that is much longer, then you don't need the ability to trigger off of very short duration pulses.
Also keep in mind that if you are going to use the hardware with any NI software product, you will have an easier time in development.

Hey Sahara,
You might want to also check out the following document called Maximizing the Performance of the NI 6534 Digital I/O Device. You might find some answers to your questions in this document, and probably some other good information that will help you make your decision. Also, if you have a PCI Express slot in your computer, you might want to take a look at the NI PCIe-6535, PCIe-6536, and PCIe-6537, depending on whether or not you need to generate or acquire at high transfer rates.
I hope this helps. Please let us know if you have any further questions or concerns. Thanks, and have a great day.
Regards,
DJ L.

Sahara,
The questions that you have are definitely valid. In addition to DJs answer I would like to add some other comparisons that will help you.
- One big different between the products you mention is the bus. The 7300A is PCIe based where as the 6534 is PCI based so the comparison might not be completely valid. Like DJ mentioned, the PCIe-6535, PCIe-6536, and PCIe-6537 are also PCI Express based and can achieve up to 200 MB/s of data streaming (80 for the 7300).
- On board memory: Onboard memory acts as a buffer for generating or acquiring. If there is no buffer in between, if your PC cannot keep up with the data that is being acquired, your data will be overwritten or an error could occur. The memory on the 6534 also allows regeneration in hardware.
- IO Configurations: Devices like the one you are referring to have banks or ports that you can configure. For example 16-CH DI & 16-CH DO, 32-CH DI or 32-CH DO will let you configure your channels for input or output (for the 7300A).
Using the 6534 you can select the data width of transfer based on this table.
Transfer Width Possible Port Combinations Timing Controllers That Can Be Used
8 bits Port 0 (P0.<0..7>) Group 0
Port 2 (P2.<0..7>) Group 1
16 bits Port 0, Port 1 Group 0
Port 2, Port 3 Group 1
32 bits Port 0, Port 1, Port 2, Port3 Group 0
- Dennis also brought up an important point.
Also keep in mind that if you are going to use the hardware with any NI software product, you will have an easier time in development.
I am not sure if you have used any other National Instruments products before. These devices (NI 653X) all use the NI-DAQmx driver and can be used on any platform (LabVIEW or text based). There are a lot of example programs shipped with the driver and available online which can help you get started.
I hope some of the above points answered the questions that you have. Please let us know if you have any further questions regarding this issue. Also, keep in mind that we do have a wide offering of products, which you can choose from and customize to your application specifically. If you let us know what your application is and what you are trying to achieve we might be able to recommend the ideal product for you.
Cheers,

hi,
can any body let me know to get the idea that how, this HSDIO cards can be used as LOGIC ANALYZER?
also, do let me know that can this 6534 card be used a pattern generator of 32 channel.
what is handshaking??

Hey Sahara,
What exactly are you trying to do? Help us help you, by providing more information about what you are trying to do.
When we refer to the HSDIO cards, we are talking about the NI 654x, 655x, and 656x devices, which can generate and aquire with clock rates up to 200 MHz, similar to what Logic Analyzers can achieve. How fast do you need to acquire your data at, or what kind of clock rate will you be running at?
Yes, the 6534 can generate 32 bit patterns up to 20 MHz (on 32 channels).
Please download the NI 6533/6534 for DAQmx Help and then search for "handshaking" to read more about it.
Regards,
DJ L.

I want configuring of individual channels with DAQ Assistant for PCI 6534
i wanted to configure few channels as input and few as output on same board.is it possible?
At every event of external trigger I want to dump a bit pattern at some of the individual channel of PCI6534 and also to acquire data from remaining channel of same board, help me if someone has a VI to do that.
thanks
