NAT9914 Hardware Interface Design

I'm designing a GPIB interface using the NAT9914. In the AN-110 Application note, there is a schematic that shows how to connect the 75160 GPIB transceiver to the NAT9914 (schematic on page 4). HOWEVER, in the NAT9914 Reference Manual (page 7-6) there is a different schematic. There is an additional OR gate between the NAT9914 (EOI and ATN signals) and the PE control of the 75160. Which schematic is correct? (And why do you think your choice is the correct one?)
Thanks in advance for your reponse!!

"When this control input, denoted PE, is in the high
state, the bus outputs operate in the high-speed totem-pole mode. When PE is in the low state, the bus outputs operate as open collector outputs which are necessary for parallel polling."
This is from a DS75160 data sheet. The reverse logic of GPIB and the OR gate will automatically convert the 75160 to open collector when a parallel poll is occurring (ATN and EOI logically asserted). You should probably follow the NAT9914 manual since it handles the parallel poll case correctly.

  • What hardware interface to use

    Hi ppl,
    I am new to labview and need some info on hardware interface.
    The objective is to attenuate a signal. We need 8 inputs and 8 output ports.
    All we have to do is take in the signal from a input cable, attenuate and send the output to the o/p cable.
    I was thinking GPIB board. How do you connect the cables to the GPIB board?
    Do I need any extra hardware?
    Any other cheaper option would be great.
    Thank you guy!

    Hi,
    A GPIB board is a control interface, sort of like the serial port, for communicating with instruments, printers,plotters that have GPIB interfaces as well. It really isn't designed to be used as an direct I/O, but rather a specialized communications port. I was going to say it is like the parallel port, which technically it is, but I had just answered a question on interfacing inputs to the parallel port in another thread. I'm guessing that you have the GPIB board, if not, if you are looking at what interface card to buy there are a lot of possibilities, mostly dependent on your technical requirements and funds available. As I mentioned, it is possible to use the parallel port, and what you are describing might be better served by an external, "controlled" attenuator. It sounds like you want to pass a group of signals through some type of controlled attenuation. I'm not sure, without spending a little more time thinking about it, of anything readily available on the NI site. It also is dependent on the signal levels, frequency, expected attenuation, etc.
    Give us a little more info on what you are trying to do,

  • DO i need some extra hardware interface for receving both Audio and video

    hi i m doing e-learning project. i have to capture video from webcam and voice from headphone and send to client.
    but my code is working fine for either one at a time.
    DO i need some extra hardware interface for receving both Audio and video. im using code AVTransmit and AVReceive found from this site only
    After running TX
    i give Dsound:// & vfw://0 in Media Locater only sound is received and no vedio
    and when i give vfw://0 in Media Locater only live video is transmited.
    im using JMF1.1.2e.
    if any one know the method to run or cause of it plz reply me soon. i will be very thankfull
    transmiter/server side code .first run TX on server

    I do this all the time, I put my MBP to a 60 inch Sharp. If you have the video working do the simple thing first. Check to make sure your sound is on your TV and Mac. Then if that doesn't work go to System Prefrences and under sound go to a tab called Output and see if your TV is listed and if it is change it to that setting

  • No Refreshed Interface Design in After Effects CC 2014

    Sort of an odd question, but how do you change the interface design in After Effects CC 2014 to be the new "Refreshed Interface Design"? Like with the blue text color, borders, and different look panels (as seen in the first image linked). I updated to Adobe After Effects CC 2014 yesterday, and for some reason, my interface design has not changed at all. Is there somewhere in preferences where I can change this? I would appreciate any help, thanks.
    What it is supposed to look like:
    http://helpx.adobe.com/after-effects/using/whats-new/_jcr_content/main-pars/image_1.img.pn g/ae-interface.png
    What my After Effects looks like:
    http://puu.sh/dfYbm/aa366e60fd.png

    Your second image shows After Effects CC 2014 (13.0). The new UI comes with After Effects CC 2014 (13.1).
    I'm curious about how, exactly, you installed the software, since you should have gotten After Effects CC 2014 (13.1.1) if you installed from the Creative Cloud service.

  • HARDWARE interfacing and software routines

    Hello there,
    I am interested in finding out a really basic tutorial/note which will allow me to work with the basic communication protocols like SPI , RS 232, etherner, USB, etc. I am looking for tutorial with BOTH HARDWARE interfacing  and software routines.
    Multiple websites will be ok for me.
    I have searched wikipedia and lot of power point presentations but was not successful in landing up with a COMPLETE tutorial which explains the hardware interfacing connections and software.
    If you guys can suggest an evaluation kit where i can pracice the above interfacing and software routine..... by all means do let me know.
    Looking forward to your reply.

    Technically you can do everything you are talking about for free provided you have the internet tool kit installed (Full Development Suite) and depending on what level of detail you plan on going into.
    If you want to play with RS232 you can start with just taking the existing Labview example, "Basic Serial Write and Read.vi" under Labview Help -> Find Examples.  You can find a serial cable and connect it to your Comm port.  On the other end of the Comm port you can insert a small wire to short pin 2 to pin 3 (TX to RX).  You will then be able to send and recieve data on the same vi.  I would look at wikipedia to learn more:  http://en.wikipedia.org/wiki/RS-232
    If you have the internet tool kit install then you can do all kinds of stuff with just a regular internet connection.  For example any place where you can Telnet you could test using the "Telnet Line Client.vi" provided by Labview.  Again I would start by consulting wikipedia if you have questions:  http://en.wikipedia.org/wiki/Telnet
    If you are trying to do everything down to the hardware level then this is a little more involved.  Again break your post into smaller pieces and repost on the Labview forum and you will have better luck getting detailed responses.
    You should not have to spend much money to play around.  You can build a lot of this stuff yourself or you can purchase very cheep if you shop around.  For example you can implement SPI using a parallel port but you need to know what your target SPI interface will be.  Regards, SS 

  • CS5/CS4 GUI User Interface Design

    I have always been very unimpressed with the user interface design on Adobe CS4.  It's riddled with problems and changes that make no sense and offer no advantages.
    For example, there is no longer a normal Windows title bar in many of the CS4 apps.  This makes it much more difficult to maximize/restore applications since normally a Windows user could simply throw the mouse to the top edge of the screen and double click the title bar.  In fact, doing this with CS4 apps has ZERO function (it doesn't do anything).  One would think that by moving the menu commands to the top bar of the window chrome, Adobe would make these menus accessible from the top-most edge of the screen in order to increase usability.  Unfortunately this is not so and clicking the top most edge of a maximized window does nothing.
    Two other very important parts of an application user interface are the upper left and upper right corners.  Normally when a Windows application is maximized, throwing your pointer to the upper right corner and clicking will close the application.  Throwing the pointer to the upper left corner and clicking will reveal the application window menu.  This happens in ALL applications... EXCEPT for Adobe CS4 programs.  These two extremely important application window command locations have been completely disabled in Adobe CS4 apps. Clicking the upper most corner pixels in a maximized Adobe CS4 app does nothing.
    Then there's the tabbed document window interface.  If you float a document window and maximize that, normally you would expect it to become maximized within the application window as it should.  Au contraire, in Adobe CS4, the document window maximizes itself ON TOP OF the application window, thus obscuring and disabling any access to the application window's tools/commands.  I did report that as a bug during beta, but obviously it was ignored.  Seems kind of obvious to me that the fact that a user could accidentally make the entire application completely unusable by maximizing a document window might be a problem.
    It still alludes me as to why Adobe changed the CS4 user interface to something that breaks so many Windows UI conventions.  Adobe CS3 was a practically perfect user interface design on Windows.  It was very customizable, all of the normal Windows functions were properly in place.
    What's the deal with the change?
    I thought maybe the file menu was moved in place of the title bar in order to make more room for other UI elements, but it's actually pretty much the same size as the old file menu title bar combination in CS3.
    With all these changes and with all the functionality losses, what exactly have we gained in the CS4 GUI?  Seriously, I'm asking.
    Anyway, I hope Adobe starts reading the Windows User Experience Guidelines (http://msdn.microsoft.com/en-us/library/aa511331.aspx) and brings CS5 back to the way a Windows application should behave.  Proper theme adherence would be nice too.
    Which brings me to Windows 7.  I love love love the way Windows 7 groups application document previews in one taskbar icon and allows aero-peek for open windows.  Adobe CS 4 obviously does not support this since it does not have normal document windows.  I hope CS5 does because it is a great feature.  I also hope Adobe CS5 implements the Windows 7 jumplists and maybe even a more touch/multi-touch friendly interface.  I've become pretty good at processing photos in Bridge using the touchscreen, and it's very cool, but it could use some improvements.
    For an example of great user interface design, has anyone tried Office 2010 on Windows 7 yet?  http://www.istartedsomething.com/20090512/screencaps-office-2010-technical-preview-teched- 2009-keynote/
    The faded transparent title bar and tabbed ribbon interface is absolutely gorgeous.

    @Adam:
    I agree with your comments! So well said!
    And there are other issues, too -- by the color of the app window, you don't know if the window is active or inactive (focus or not in focus). Titles of panels which are inactive, are dark text over dark background -- hardly readable at all... And many more.
    I really hope Adobe are listening...

  • PC Hardware Interface

    I will be purchasing a MacMini and Airport Extreme.  I want to attach an existing IBM compatible PC (running Windows XP OS) to the network.  Can someone please tell me:
         1.  What PC hardware is required to interface with the Airport?
         2.  Does Apple sell this hardware interface.
         3.  If Apple does not sell this hardware, can someone recommend a quality component?
    Thank you...

    Connect your IBM to the AirPort using an Ethernet cable. If your IBM has a wireless card, connect it wirelessly using the standard Windows wireless interface utility in the Taskbar. All consumer wireless routers use the 802.11 standard, so all are cross-compatible.

  • Java SE Embedded hardware interface support

    What are the available options for integrating with hardware interfaces with Java SE Embedded?
    - I've noticed that the Java Comms API doesn't seem to have any recent activity, and is only provided for a small number of os+hw combinations.
    - A number of community posts elsewhere recommend RXTX (http://rxtx.qbang.org/wiki/index.php/Main_Page) - it looks like this is limited to just serial or parallel ports though - is this correct? Is this widely used?
    - I've noticed libraries like Pi4J (http://pi4j.com/) provide a great Java API to interact with the GPIO pins on the Raspberry Pi. This is a great approach if there is a library like this for the hardware platform you are running on, but if there isn't what are the alternatives? Do you have to write your own C shared libraries to integrate with the hardware, and then use this via JNI?
    Thanks, Kevin

    See Java for Mac OS X 10.5 Update 1 adds support for Java SE 6. Note the system requirements exclude PPC machines.
    Apple does not drop software support, however, they stop updating older versions because the requirements of new software exceed what older hardware can provide. This is simply the result of obsolescence. Your version of OS X is capable of supporting Java SE 6, but your hardware is not able to run that software.
    If it's essential that you be able to run new versions of software that have requirements that exceed what you hardware or OS can support, then you have to upgrade accordingly. Sell your PPC machine or donate it to a reputable charity or local school/church. Then buy a new machine that can run the software you wish to use.

  • Interface design in config profile

    Hi
    After  creation of interface design in config profile and I have assigned new tab in cu50 .
    But after I have created one sale order  , then I removed interface design object from config profile again I maintained same as like before .
    But once I changed interface design even though  I maintain again which is not updating as like before.
    Can you tell me  wt should I do  for the same?
    Regards

    pls close this issue

  • Is this new interface design right or do I still have some graphic probs ?

    Is that interface design right after the last update ?? I think the old onne looked much more clear for a better workflow... this one just looks a little cheap and strange to me ....

  • Can we demodulate the signal recieved at DAQ card without using any hardware interface(by only using labview)?

    Hi all,
    Can we demodulate the signal recieved at DAQ card without using any hardware interface(by only using labview)? if yes then how? please give brief idea.
    Regards,
    Amit

    There is probably a way to do it, but it it may be easier to use an X-series board for the job.   They support a new counter capability for count reset on a digital edge without needing to be configured in encoder position mode.  I am not sure exactly how that feature's been implemented however, so maybe it won't make things easier after all.
    The plan based on the hoped-for behavior: 
    1. Configure an X-series counter for pulse generation based on "ticks" of your clock channel.
    2. Set both initial delay and low time to the critical # of ticks.
    3. Configure for count reset on a digital edge (if possible in pulse generation mode)
    4. Configure the count reset value to be the critical # (or possibly 1 less, if possible in pulse generation mode)
    5. If you want the output to remain high indefinitely, configure the counter task to use its own output as a
    pause trigger, and pause while high.
    The way pulse generation works is to preload a # of "low time" ticks into the count register.  Then every source edge will decrement the count.  When the count reaches terminal count (0), the counter's output is toggled (or can be configured to pulse).  The register is then loaded with the # of "high time" ticks and the process continues.
    You would be perpetually interrupting the count-down process as long as you got your triggers in time.  The count would keep getting reset to the # of low counts, keep decrementing toward 0 without reaching it, and so on.  If ever you did reach 0, the output state would toggle high, then the high state would prevent subsequent clock signals from decrementing the count.
    You can conceivably do a similar thing with a 6601, but I'm pretty sure you'd need 2 counters working together to get it working.

  • Cisco 5508 interface design problem

    Cisco 5508 interface design
    now i have connect wlc into infra same picture but ap can't register into wlc. How create interface for this diagram. please help me because access switch is unmanage switch i can't config trunk on this.i can install for this solution this isn't ?
    thank you for best support.
    samy

    Why are your AP's on different Vlans?
    If you plan to create SSID's on different Vlans then you will need a trunk port to the WLC as the switch needs to pass tagged frames to it and the WLC needs to pass tagged frames back.
    Out of interest, you are using a 5508 which is a fairly expensive piece of kit yet you are connecting it to an unmanaged switch. Why?

  • Interface Designer: "Reading Class File" fails

    I'm just trying the Apple Cocoa Tutorial (ConcurrencyConverter). I have a problem at the point where you shall load the class file "ConverterController.h" into the Interface Designer. It always fails with the error "Parsed 1 source file, but no buttons were found...".
    Even when I copy and paste the header file from the tutorial it doesn't work. It looks like this:
    #import <Cocoa/Cocoa.h>
    @interface ConverterController : NSObject {
    IBOutlet NSTextField *amountField;
    IBOutlet NSTextField *dollarField;
    IBOutlet NSTextField *rateField;
    - (IBAction)convert:(id)sender;
    @end
    I have no idea what to do now, can you help me?

    Your note about the outlets etc actually being there but needing to look harder made me stare at the screen for a few minutes ... I can't see them though.
    Maybe they just don't show up in Xcode 3.2.1???
    Hi DF -
    I don't know how to guide you further since I don't have 3.2.1. Did you see Ruud's most recent post?
    Ruud Wijnands wrote:
    ... if you click on the connections tab they are shown there in in unconnected state.
    Assuming this much hasn't changed since 3.1.4, besides the Class Outlets table in the Identity Inspector, there are two places to look for Outlet and Action connections:
    1) When you ctrl-click on an object (e.g. the icon for a controller), a black, floating panel should come up listing all connections from and to that object. Be sure to select the object in the xib (icon) window with the View Mode switch in the Center position. With that View Mode setting, the xib window should display a two column table with a tree of small icons to the left. By expanding the nodes in that tree you should be able to find every object in the xib;
    2) When you select an object (in the xib window as above), the Connections Inspector (cmd-5) should display all possible connections from and to the object. I assume this is the view Ruud referred to as "the connections tab".
    I don't recall seeing a case where the black panel list differed from the list shown in the Connections Inspector, but it wouldn't hurt to look at both. If neither of the above finds the connections when _you've seen your custom class in the Identity list, and set the object in question to that class_, I might suggest closing the xib and restarting IB. You could also try modifying and resaving your custom object's @interface file just to stir things up a bit (e.g., remove all the IBOutlet declarations, save, then add them and resave).
    It might also help to start a new project and do nothing else but add one custom class to see if you have better luck getting IB to import the correct connections in the new context. E.g., add a NSObject subclass named Foo with one ivar such as IBOutlet NSWindow *Bar; then see if you can add a blue cube to MainMenu.xib, set its identity to Foo class and see the Bar outlet.
    For more details on connecting custom objects, see "Setting the Class of an Object" and "Injecting Class Information into a Nib File" under Xcode Integration in the +Interface Builder User Guide+.
    Of course it's possible we're dealing with a bug that's unique to 64-bit 3.2.1. I've searched the web, the 3.2.1 Release Notes and the Xcode Mailing List for reports that might confirm this, but haven't found anything interesting yet. So I think we should continue to assume that Xcode 3.2.1 is capable of obtaining custom class info, and we're just dealing with some misunderstanding. Hopefully, one of our forum experts who has 3.2.1 will join the thread to shed some more light on the topic.

    After running TX
    i give dsound:// & vfw://0 in Media Locater only sound is received and no vedio
    and when i give vfw://0 in Media Locater only live video is transmited.
    im using JMF1.1.2e.
    if any one know the method to run or cause of it plz reply me soon. i will be very thankfull

    I'm also getting some really bad sound quality on facebook notifications. I've been forced to disable them they sound horrible like they are clipping.
    Trying to figure out if this is a problem on all Late 2013 15" macbook pros or if mine is defective? This occurs even at around 20-30% volume levels with the Facebook notification sound problems...
