What advantage is there in using the NI USB-232/4 on a standard USB Serial Hub?

What advantage is there to use the NI USB-232/4 on a shift to USE of concentrator series?

I have an application that requires LabVIEW control of 19 instruments that communicate via RS - 232.

I have read the Datasheet for the NI USB-232/4, and I see no benefit of spending $528 for this unit (five times) on a standard USB to Serial hub for half the price.

Can someone tell me if there is an advantage for the NI USB-232/4 or if they have had experince with one?

Thanks in advance.

Thank you, NYC for the quick response.

Why you prefer that your desktop with taken PCI card in charge of ports series? The space? COM stable #s?

COM stable #s, harder to disconnect randomly, don't have to worry about the bus power, do not have to worry about Windows randomly powering buses as a feature, reliability, often less expensive energy saving...

  • I lost the disc to restore my phone and it is no longer supported by the manufacturer. Can I use the installation disc for my desktop with my laptop serial number?

    I lost my laptop computer restore disc and it is no longer supported by the manufacturer. Can I use the installation disc for my desktop with my laptop serial number?

    My title says it all. I have an old HP laptop that they do not send to restore the disc more (I don't know yet I had one; his old laptop from my brother) and I have an installation disc for my new PC. I have a Windows XP Home edition SP2 installation disc. However, as the hard drive of my laptop broke down, I don't know what version of windows it was. I think it should have been an OEM version and the sticker says it was Windows XP Home Edition.

    Now, anyway I tried to install my installation on laptop computer disc, offering series of laptop computer but now it asks me to activate. Will it work if I activate it?

    Thank you

    Unless you are lucky enough to know someone who has a generic OEM drive, which you can borrow, I don't see a practical solution for you.  I advise you to spend the money to buy one, even if you could find one to buy from a reliable source (not eBay!).  Although a generic OEM disc should work with your product key, there is no guarantee that it will work with your product key.

    If your laptop can be retrieved through a restore partition, and you can't borrow a disc that will work with your product key, then you have pretty much exhausted all reasonable or practical options.

    I finally did! I borrowed a copy of a generic OEM drive, through activation and it is!

    Thank you much for the help...

    Now I've done could you help me more? Say now, I returned the drive OEM back (don't want to make an illegal copy) and want to be able to use my current system installed to generate a system disk that will allow me to avoid all the problems I've had up to now. What would you recommend? I've read a few articles on other forums (I did some research!) but is a little confusing. I hope you could help.

    Thank you

  • Read only the SPI using the box USB-8451

    I am using the NI USB-8451 box to read the SPI of a Honeywell digital pressure transducer data.  The difficulty comes from that part of Honeywell uses only the SPI in half-duplex mode, meaning that it only transmits data, but does not require anything beyond the appropriate chip select signal and SCLK to start transmitting its 32-bit sensor data.  To facilitate experimentation with the sensor, I bought a USB-8451 SPI Interface thinking I could easily configure the 8451 to read data from the sensor.

    However, if I understand the situation, there is a problem.  The 8451 considers full duplex data, i.e. a data word must first be sent to the SPI device in question before the unit will start to transmit back data of its own.  And since the MOSI data writing periods, since this particular device starts transmitting immediately once a clock is applied, synchronizing the unused address data will cause the unit will return its data before the 8451 begins listening for data in return.  The call used by the 8451 to write read action can be divided into the individual reading and actions of writing of any kind that I could discover.

    Can someone tell me if I missed something in this operation or if there is some quick tips, that I could use to be able to use the 8451 therefor?  Thank you!

    Doug G.

    Exactly correct. It's nice when things are easier than expected. Hope it works as easy as it sounds.

  • Cannot use the Micro-USB port on the coming Pro 11?

    Hello

    Can I use the micro-USB port to a mouse or other device (with Dell micro-USB to USB dongle for tablets)?

    Bought one as advertised and does not work...

    Thank you

    Hey guys, it seems that there is still much confusion over the functions of the port mictousb on the place of the 11 sessions pro.

    Anyone know if it is possible to use it for anything other than recharging? An OTG cable connected I have here doen't work on my 7130, but on ebay, some sellers here in Germany offer small hubs with OTG funcion specially for this model:

    http://www.eBay.de/ITM/kwmobile-3In1-micro-USB-hub-adapter-fur-Dell-venue-11-Pro-Schwarz-Verteiler-Kit-/361194175623

    Does anyone know for sure who is the truth?

    EDIT: also, as the microusb port has the logo of bolt on I guess this is the port used for the powershare function (if this feature is enabled in the BIOS). Does this mean I have to buy a microusb to microusb cable to recharge my mobile hollow 11 meeting places powershare function?

  • Using the NI USB-6009 case to generate a 12VDC output and output current of 300mA

    Hello

    I use the OR-USB-6009 my power supply for a 12VDC with drive current of 300 solenoid my. Initially, I used a non reverse Op-amp circuit and Inverter circuit operational amplifier to get the + 12V and - 12V output but I could not get the current I required. Should I use a transistor?

    Please find attached photos. Any input would be appreciated.

    Thank you

    Adam

    Well, really depend on your piercing circuit.  But I used most systems use the transistor to set the voltage of the device to 0V.  So when your DIO is high, the output is actually 0V (low).  So using a converter chip, your release of the DIO will be sort of the output circuit.  If you get the right IC, then the inverter will give you also a few extra current to drive your transistor.

  • Info satellite A210 171 what do I need before using the recovery disk?

    Hello

    I have 1 recovery disk that came with my equium, have not used before.
    It says on the back of the envelope of recovery disk 'insert the first diskette.

    I guess there should be a second?

    Also this info I need to provide during the installation process? as serial number?
    All I have a black and white sticker that is on the side of the box, it came in, but it was so long ago.

    I'm having a lot of problems with windows install does not and many others.
    Windows updates do not work either and I tried to correct those, but a clean reinstall of the operating system has been recommended.
    Now, at this point nothing will install because windows setup will not work.
    So I think I wil lhave to try a clean install, but I do know that the cd player works.

    I got a great run on this laptop, little slow today for my needs, but all very good product, purchased in 2007.
    With a clean OS and 4 GB of ram that could last for years, cannot afford a new right now.
    I really tried to avoid using a disc of recovery in the past, as I have never had problems until now.

    Thank you

    I m wondering why you get this disc with your laptop, why? Because I do not have the recovery disk, but I had to create one using the Toshiba recovery disc creator software
    But my laptop is more recent that your A210 might be the reason why you have this drive

    I have created a recovery disk and I needed two-disc DVD, I think it depends on the size of the image file

    > Also what information I need to provide during the installation process? as serial number?
    This is not necessary because your system has already been activated.

    But I recommend you backup your personal data, because the recovery disk would format the whole HARD drive and you will lose the files.

    PS: you should read other threads in product recovery forum!

  • What RAM I need to use the Satellite Pro M70-144

    Can someone tell me how to put extra RAM?

    Hello

    It seems that this laptop just support DDR2 400/533 memory modules.
    You can upgrade the memory for max 2048 MB and you use these modules:
    DDR2 400/533 256 MB (PA3389U - 1 M 25)
    512 MB DDR2-400/533 (PA3412U - 1 M 51)
    1 GB OF DDR2 400/533 (PA3411U-1M1G)

    These modules are 100% compatible and it works like a dream ;)

  • How s/n know when and what account perform a function using the database link?

    Dear,

    My application of the CIM team asked DBA to create new function and run it. Function must use the database link for remote database data. So I need to create a new database to their licensing link. Cause we guess we'll experience the performance issue after the user performs this function, or another question and errors may occur. So we want to know when and who use this feature that connects to a remote database through the new database connection in advance. And I also need to know when and which connect to the remote database using this new database link. We have no idea to get this information?  Can anyone recommend how do? Thank you very much.

    Best reqards, Otis.

    Check what business purpose, it will solve.  If the function is so safe, why everyone will use. Only admin people should access.

    All of these additional controls of this kind must be avoided as much as possible to improve the overall performance of the application.

    Still if you need, see the database audit mechanism, specifically designed for this type of activity.

    Kind regards

    Hello

    Of course, you should be able to combine these queries, something like this:

    select calendar_code
         , calendar_date
         , seq_num
         , sum ( CASE
               WHEN  bcd.seq_num IS NULL
               THEN  0
               WHEN  bcd.calendar_date < TRUNC (SYSDATE)
               THEN  1
               ELSE  -1
              END
            ) over ( partition by  bcd.calendar_code
                  ,            SIGN (SYSDATE - bcd.calendar_date)
                  order by        ABS  (SYSDATE - bcd.calendar_date)
                ) workdays_ago
    from   bom.bom_calendar_dates bcd
    where  calendar_code = 'SAC-WRKDAY'
    and    trunc(bcd.calendar_date) < trunc(sysdate)
    

    If you do not want to display some CREATE TABLE and INSERT statements for the sample data, and then I could test it.

    Good thinking!
    When the two branches of the UNION query the same table, there is usually a more effective way: something that only requires a pass through the table.

  • What event is captured from using the Central button of the Joystick?
