OR close Switch
Close the vi appellant NOR switch resets the relay/switch in a known state, or they keep their State existing?
The UUT is connected to our card PXI-2568 31 SPST shouldn't have some of these switches changed while it is turned on. If the switch cards can be closed without changing the State of the switches, I can avoid the extra wires necessary to check the status of power supply and worry not for sequencing when stopping down.
Hi NickDngc,
Thanks for posting on the forums. I was able to run tests, and a switch will stay in the stay in open or closed position, until you or the other power down the chassis, or reset the unit. When you call an OR-Switch initialize VI, make sure a fake contant of wire in the Terminal to reset device, because the default value is true. If you turn off the chassis or reset the device however, they will return to the initial state, that is open.
I hope this helps.
Kind regards
Brian P.

OK to mix 'of connection to the switch"and"close relay switch?
Hi all
I'm developing a test sequence using the card multiplexer 2527 to the track signals. To configure the card, I use DAQmx switch functions. In my application, I have a Subvi routine that imports the data from a spreadsheet Setup and run a loop for to set the configuration for each step (each iteration of the loop contains the channel for 2527 card information). The topology is set on the first iteration, as well as the configuration of the path to the first string.
My concern is this: I need to close the extra channels/relays without changing the topology or resetting the device. In the first round, I use "connection to the switch" function to set the initial path, (ch0 to com0 for example). Then in subsequent iterations of the loop, I use "Relay close switch" function to close the additional channels individually (for example k2). In the end, when the measure is taken, both ch0 ch2 must be closed and routed to com0. This implementation is so sure, or am I somehow to make the adjustments to the initial loop?
I would like to test this with the hardware, but it is not yet available.
Also, I realize that I could use independent topology and configure all relays individually for each step, but I hope that my approach will be easier and safer.
Please notify. Thank you.

Hello GSinMN,
It's OK to mix 'of connection to the switch"and"Close relay switch"If you understand what's happening below. "Switch Connect" connects two channels by closing a path of relay between the channels, then "Close relay switch" can be used to change the State of the individual relays. If you are not careful you can mess up your connection by activating / deactivating relays that are part of the route connecting your channels.
"Also, I realize that I could use independent topology and configure all relays individually for each step, but I hope that my approach will be easier and safer."
I would recommend the topology independent if you want to stick with connections to channels only. http://zone.NI.com/reference/en-XX/help/375472G-01/switch/2527_independent/
Initial connection:
CH0-> pcom0
pcom0plus-> icom0plus
pcom0minus-> icom0minus
icom0-> com0
In each future iteration just connect to the next to pcom0 channel (which will be indirectly connect it to com0):
CH1-> pcom0
CH2-> pcom0

I try to use the /close switch with media player 12 on windows 7 32-bit o/s, the media player opens and plays the file but does not close after the reading of the file.
I expect that the /close should work when used in conjunctino with the /play after reading the site--> http://support.microsoft.com/KB/241422
Some commands I tried:
Start/min Mplayer2.exe /play/c:\alert.wav nearby

Delete or remove application menu item switch
Hello
I use blackberry api 4.3 for my application and I tested this application in my simulators(9500/9530) api 4.7.
I don't want to remove all of the default menus (like showkeyboard or hide keyboard, see the symbols, close, switch application).
I want to delete or remove only switchapplication of the menu item. So is it possible then you can you please give some more
information about this problem.
Thank you
MINDUS
Sorry, my mistake. You're right, you do not see the menu system default items in makeMenu. Instead, you override getMenu, call super.getMenu () and then search & delete. The ordinal is 268501000 (it's a hack, because this number may change).
I think you should resolve your question a little differently. I suggest that you add your own Application Switch menu only if the OS does not provide its own, as the point provided operating system will work better.

After the upgrade to the latest iOS 9.2.1 I lost several songs I downloaded and paid through iTunes. To contact Apple "Genius Support" told me that the songs have been not "saved." Whiskey Tango Foxtrot. Is what a decade of what century new? Have we seriously save the music on our PC for access? These are all iTunes store buys you mind... not the CD or downloaded/ripped music elsewhere that I am trying to sync to my iPhone. I can't believe I lost so many music (AND MONEY DOWN THE DRAIN).
It comes to my iPhone 6, but I'm getting closer switching to Android... almost done also, I plug a 5 s Galaxy, to deny and buy more 6... should have switch to Android.
If you want the secure Yes, you need to back up. A single copy of a song is not safe.

I'm trying to fix the HP Pavilion G7-2022US laptop from a friend, the number of product B4Z74UA. The laptop starts in Windows 7, but the screen is dark even during the BIOS or by MAIL.
Symptoms:
Laptop turns on but the LCD screen stays dark (during the POST and when Windows loads)
With the help of a flashlight on the display shows that the video is present but the backlight does not work
The video can be seen on an external display connected via VGA cableWhat I've done so far:
Installed a new LCD screen cable
Installed a new LCD screen
Update BIOS
Updated graphic driver
check that the lid close switch works (small magnet under the screen that signals the motherboard to turn off display when the lid is closed)
Static discharge by keeping the button depressed with battery and power adapter disconnected
Checked if RAM could be badI tried all the solutions above, but the screen remains dark. The only way to use the laptop is to connect it to an external monitor. I disassembled the laptop together and there is no inverter part to replace.
I don't know what else to do. Any suggestions?
I finally found the culprit. A circuit of (possibly a fuse mounted on surface) on the motherboard next to the display cable connector is visibly burned. The circuit is too damaged to solder and close the connection.

Re: Screen Equium A200 is low
Hello
I have a Toshiba Equium A200 computer laptop with a dark screen. I changed the inverter and the screen but the image is
always off.
I came to the conclusion that near the lid switch was defective but have disassembled the laptop and can't find for the life of me, there.I'm going blind or this laptop isn't one - which I thought unusual.
Can anyone help?
Thanks in advance.
Can I ask you why you came to this conclusion?
Your screen is completely black?For me it makes no sense to the search and replacing any lid close switch if the screen is small
I think she s inverter question even a FL. It could also be a display problem, but I m not 100% surePerhaps you have not installed the FL inverter correctly or maybe you used a bad part
I think you should contact the laptop technician to find out what's going wrong with your laptop!

I have an Officejet4620 printer all in one that ad hoc stop printing and displays the message "turn power off, t. It turns off the power button and the only solution is to unplug it and plug it back again. At this point, he said to me "to avoid damage use the close button. Do not use a wall or the band to close switch '!
It solves the problem, but appreciate any advice on what I can do to prevent it in the first place.
Hi xiota,
Welcome to the HP forums!
I see that you are having a problem with your Officejet 4620 advise there need to be in the off position you will only do so by pulling on the power cord to the rear. I'm sorry to hear that, but I'll certainly do my best to help
There are certainly a few things that I will propose, but first of all, I'm just curious as to what you mean by "what adhoc stop printing... » ? The printer is connected to the computer via an ad-hoc connection?
First of all, I would recommend you connect the printer directly to a wall jack to make sure it is getting the right amount of power. If it is already plugged into a wall or that doesn't seem to change anything, please make sure that your printer is the latest Firmware and updates. If the printer is not connected to your wireless network, please install the firmware on your computer with this HP Officejet Firmware link.
I would like to know how these steps are for you!

Salvation of the of-My Photosmart C6180 All in one has worked wonderfully for me for several years the wireless, but now after getting a new IMac computer, I get a continuous string of the same message "to avoid damage on the button to turn off the printer. Do not use a wall or the band to close switch"I can't turn it off at the power point, but I can't be sure. Its also very hard to close it using only one pass now. Question: Can the ' damage 'fixed. ' If Yes please tell me how. I would appreciate.
Hi Battleron,
Thank you for visiting the Forums HP's Support and welcome. I read your thread on your HP Photosmart C6180 printer and saw issues of power. Plug the power supply directly into a wall works and in the computer. Do not connect it a power strip, surge arrester, or secondary power source because they may cause this problem. This should solve your problem. No damage occurred, that it is a failure of communication and just need to restart or reset.
Hope that answers your concerns.
Thank you.

Connection of the accelerometer
Dear all,
I am writing a progrma that make use of the accelerometer to detect the orientation of the screen.
The structure of my program is as below:
I have a class call 'ABC', that the main function is in this class. In the main function, I use the pushscreen command to push the screen of another class 'DEF '. And I want to exec the acceleormeter in the class "DEF". If I use the command to open a connection to the accelerometer but it always return a null value. I can't open the accelerometer and detect the orientation of the screen.
Here is my code:
Class ABC:
import net.rim.device.api.applicationcontrol.ApplicationPermissions; import net.rim.device.api.applicationcontrol.ApplicationPermissionsManager; import net.rim.device.api.system.Display; import net.rim.device.api.ui.Ui; import net.rim.device.api.ui.UiApplication; public class ABC extends UiApplication //ABC class { public static void main(String[] args) { /*Create a new thread of the application and make the currently running thread the application's event dispatch thread*/ ABC app = new ABC(); app.enterEventDispatcher(); } //Constructor public ABC() { pushScreen(new DEF()); } } //End of ABC
Class DEF:
import java.io.IOException; import java.util.Vector; import javax.bluetooth.BluetoothStateException; import javax.bluetooth.DataElement; import javax.bluetooth.DeviceClass; import javax.bluetooth.DiscoveryAgent; import javax.bluetooth.DiscoveryListener; import javax.bluetooth.LocalDevice; import javax.bluetooth.RemoteDevice; import javax.bluetooth.ServiceRecord; import javax.bluetooth.UUID; import net.rim.device.api.bluetooth.BluetoothSerialPort; import net.rim.device.api.system.AccelerometerSensor; import net.rim.device.api.system.Application; import net.rim.device.api.system.Backlight; import net.rim.device.api.system.Bitmap; import net.rim.device.api.system.Display; import net.rim.device.api.system.AccelerometerSensor.Channel; import net.rim.device.api.ui.Graphics; import net.rim.device.api.ui.MenuItem; import net.rim.device.api.ui.Ui; import net.rim.device.api.ui.UiApplication; import net.rim.device.api.ui.component.Status; import net.rim.device.api.ui.container.MainScreen; public final class DEF extends MainScreen //DEF class implements DiscoveryListener { //Constructor public DEF() //DEF { } //End of initscreen public void serviceSearchCompleted(int transID, int respCode) //servicesearchcompleted { // TODO Auto-generated method stub switch (respCode) //Select which response code { case SERVICE_SEARCH_COMPLETED: //Service search completed if (AccelerometerSensor.isSupported()) //Accelerometer is support { Channel accchan; //Start querying the accelerometer sensor //accchan = AccelerometerSensor.openRawDataChannel(super.getApplication()); //accchan = AccelerometerSensor.openRawDataChannel(UiApplication.getApplication()); //accchan = AccelerometerSensor.openRawDataChannel(UiApplication.getUiApplication()); //accchan = AccelerometerSensor.openRawDataChannel(Application.getApplication()); //accchan = AccelerometerSensor.openRawDataChannel(this.getApplication()); //accchan = AccelerometerSensor.openRawDataChannel(motor_car_2.getApplication()); int ori = accchan.getOrientation(); //Stop querying the sensor accchan.close(); switch (ori) //Select which direction { case AccelerometerSensor.ORIENTATION_BOTTOM_UP: //North case AccelerometerSensor.ORIENTATION_TOP_UP: //North case AccelerometerSensor.ORIENTATION_RIGHT_UP: //West //Force to west direction Ui.getUiEngineInstance().setAcceptableDirections(Display.DIRECTION_WEST); break; //End of north or west case AccelerometerSensor.ORIENTATION_LEFT_UP: default: //East, horizontal or unknown //Force to east direction Ui.getUiEngineInstance().setAcceptableDirections(Display.DIRECTION_EAST); break; //End of east, horizontal or unknown } //End of select which direction } else //Accelerometer is not support { } //End of accelerometer is not support break; //End of service search completed } //End of select whioch response code } //End of servicesearchcompleted } //End of DEF class
I think that this problem may be due to my poor concept in Java. Please provide some tips.
Note: The class DEF is a listener of bluetooth device discovery. I run in debug mode and make sure that the code executed at these lines open the accelerometer. But all return null. So I can't treat more steps.
My target is to detect the orientation of the screen and the limit to this complementary process direction.
Thank you for your help in advance.
Best regards
Albert Siu
Fix there issue.
The issue is due to bad I opened the channel as a channel of raw. If it throws an exception in the getorientation function.
Thanks for your help.

or-switch close or open the relay with an entry 1 or 0
I try to open and close relays on the pxi-2503 or-Switch with a 0 or a 1 entry in the node of relay action. I am trying to replace the constant control of opening and closing by a 0 or 1. The digital input is respectively 20 and 21, these integers they control relay. How can I change the values 0 and 1. I deleted the order of opening and closing of the driver itself and connected an integer constant in the pilot I32 node. I made the mistake of saving it. Now the relay returns an error as the sink empties and all relays now have a cut wire and no control input. I tried undo it and wiring of control of origin (open/close) for the entry I32. It continues to error. I'm Noah re - install the drivers or switch. All I need is a solution so that the relay to accept 1 or 0 for relay control.
Hi Martin,
Starting from the example VI, you need not to change anything with the VI relay control. All you have to do is input a 20 to open the relay or a 21 to close the relay. If you work on 0 to close and 1 to open you can have him in place so that opt-out of the control of the 21. This way, if your control is to give a value of 0 you get 21-0 = 21 enter the VI of relay control that will close the relay. If you have a value of 1 from control you get 21-1 = 20 go to the command of the relay which will open the relay.

Close application when the application switch menu item to invoke
Hello, I made application for blackberry (os 5,6,7), but it has a strange behavior.
When I press the switch application menu item, my request is close, so I can't get back to my application once I switched to another application.
I have replace my onClose to be like this
public boolean onClose()
{
This.Close ();
Returns true;
UiApplication.getUiApplication () .requestBackground ();
getApplication () .requestBackground ();
Returns true;
}but the problem remains.
Please help me solve this problem
When you change your application, the close method is not pushed directly so I think that you look elsewhere this
Try to use the Application Switch with an application example - say the sample HelloWorld application. I think he won't, which suggests that the problem is in your application.
There are three places to look:
(a) the Application disable method is pressed when the request is sent to the background. Maybe you have coded it and it closes the application
(b) you have a certain type of background processing controls (isForeground()) and reacts according to what it finds.
(c) in the method onObscured() to one of theFields/screen on the display at once. .
Other than that, I think you're looking for a general bug in your application. The starting point is to look at the debugging log when you do this - look for anything from your application you consider odd.
