Help needed to use USB 9481 relay device

I am new to LabVIEW so any help would be appreciated.
I am attempting to start and stop an instrument with the USB-9481 relay device. On my instrument, connecting pins 1 and 2 will start the machine, and connecting pins 4 and 5 will stop the machine. How do I program LabVIEW to connect pins 1 and 2, wait a determined time, disconnect the connection, and then connect pins 4 and 5? No power needs to be supplied since the 12V is already being supplied by pins 2 and 4.
Thanks so much.

Hi Josh, No problem. I took a look in the NI 9481 Operating Instructions and found this information to be quite useful:
As far as the DAQ Assistant goes, you can only have 1 DAQ Assistant per device, so you will need to add channels to the DAQ Assistant by pressing the '+' button near the top left (just below the Play button). This device is pretty simple, and I'm sure you'll be using it in no time.

Help needed on using hardware tokens / Smart Cards for encryption

I need help in filling the following gap in my understanding
I know about
1. Using keys in Java keystores to encrypt/decrypt data (Signing, symmetric encryption)
2. Using Keytool to export a digital certificate to a keystore.
I need help in knowing
1. How the certificate stored in secret device is shared with java key stores. Do I need to use some special library.
2. Is the process of encrypting Secret Key bytes defferent from wrapping the key?
Specifically, I want to use iKey (USB based security hardware token) in my system, which says that it supports
�� The PKCS#11 standard library
�� The MSCAPI and CSP standard libraries
�� Using automatic certificate registration

> We have a current Server with 4 x 4 cores, 64 GB RAM, 6TB HDD, Windows 2K8 R2 and SQL Server 2K8 R2. On this server we have installed 6 SAP Servers(both ABAP and JAVA based). We want to install two more SAP servers on this machine but planning to use the Hyper-V Mode to ensure that there is no conflict. With this background here are my queries.
You should not run SAP instances on the server with the hypervisor (the OS running on the metal). If you want to virtualize, then do it for all instances.

If they are running on the same OS you will always take images of everything.

So those 6 servers are virtualized already??

The safest way is to do a homogeneous system copy.

According to

this should not be done.

What is the disadvantage of using USB 3.0 device through USB 2.0 port?

My mac only has USB 2.0 but I'm told to use an external drive with USB 3.0 for better speed. Do I forfeit the 3.0 speed by plugging into a 2.0 port? Even though the 3.0 device is compatible with 2.0, is there a disadvantage?

Thanks for the reply. So basically, if I want to fully utilize the speeds available for USB 3.0 devices, I need a new mac, right? Is there an adapter or workaround? I have memory-intensive sound libraries for use with Logic that are recommended to be stored/run from a SSD or 7200 rpm USB 3.0 drive, so I'm trying to determine if it's worth it to fork out the cash for an expensive external drive, or if it doesn't gain me anything anyways because I'm limited by the USB 2.0 ports on my iMac.

Help needed for using BASIC authentication through JDBCRealm

Help needed.
Hello,
I am doing a degree project, so far it works fine in my local machine, I need to try it on my virtual hosting (as it is a live server).
My project requires JDBCRealm, that is BASIC authentication loading access data from mysql database. Normally this setup can be done in Server.xml file, because my Tomcat hosting is a virtual one, I only have permission to access the web.xml file.
My question is: is it possible to get it done in an alternative way? In web.xml? Some properties file maybe?
Thank you very much.

You can set this up for your context using META-INF/context.xml instead of working with server.xml.
Make a directory called META-INF under your webapp ( it'll be at the same level as WEB-INF ). Under this, add a context.xml with all your context specific configuration including the realm. A sample is below
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/myApp" reloadable="true">
    <Realm
        className="org.apache.catalina.realm.JDBCRealm"
        driverName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
        connectionURL="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=myDB;SelectMethod=Cursor;"
        connectionName="username" connectionPassword="password"
        digest="MD5" userTable="users" userNameCol="userid" userCredCol="userpassword"
        userRoleTable="user_roles" roleNameCol="rolename"
    />

Help needed in using the DocCheck utility

Hi
Can somebody help me to use the DocCheck utility.I need to check that all the java files have the required javadoc tags and they are correct.
I have downloaded the zip file and I have been giving the following commands
c:\javadoc -doclet com.sun.tools.doclets.doccheck.DocCheck -docletpath c:\svk\jdk1.2.2\bin\doccheck1.2b1\lib\doccheck.jar -sourcepath<full path with the file name>
But I get the following error message : No package or class specified.
I also tried giving the following command:
D:\SegaSource\sega\src\com\sega\account>javadoc -doclet com.sun.tools.doclets.do
ccheck.DocCheck -docletpath d:\jdk1.3\doccheck1.2b1\lib\doccheck.jar User.java
But I get the following message:

I have never ran the DocCheck from the command prompt, so I really don't know how to do it, but I do run it succesfully using ant (build tool from apache - jakarta, if you use tomcat you already have it installed).
So.. if you do use ant.. this will help:
<target name="doccheck" depends="prepare">
     <javadoc
          packagenames="${packages}"
                destdir="${doccheck.home}"
          doclet="com.sun.tools.doclets.doccheck.DocCheck"
          docletpath="${doccheck.path}" >
          <classpath refid="project.classpath"/>
          <sourcepath refid="project.classpath"/>
     </javadoc>
</target>If you don't use it.. I guess I was of no help, sorry.

ICan't ReInstall my computer please help. need to use Mac for school next week

I use my Mac for School and stuff happened.
Long story short.
1) I tried to reset my Mac Book Pro computer and I did.( by pressing option key and go to disk utility and erase tab and erase)
2) then I know I was supposed to go to Reinstall OS X Lion and I did but I quit. (took 10 hrs and plus my internet is bad and couldn't DL the other stuff)
3) I remembered that I had a recovery disk. so I inserted it and I went to the disk utility, dragged the Macintosh HD to the restore tab, destination, and it copied my recovery disk data? to my Machintosh HD and the name of it changed to Mac OS X Base System ( the name of my recovery disk)
4) and I tried to restart, shut down my computer, it sends me to the same Mac OS Utilities. Again.
5) so I went to Reinstall Mac OS Lion, agreed, and the download destination usually should be the Macintosh HD ( for me its Mac OS X Base System right now) but it said it is locked (because I'm dumb) and i can't install it now.
6) i don't know what to do now because this is not my computer that I'm sending this support from. and I can't use my original Mac Book. what should I do?
AND I NEED TO USE THE MAC NEXT WEEK FOR SCHOOL.
more info: MacBook Pro 13 inch Late 2011 ( got it for christmas)
OS 10.7.5 ( recovery disk is 10.7.2)
had no problems for 2 years.
Why is Internet bad? Japan. thats why.
For those who wonder why I wanted to reset/restore my MacBook Pro or, want to hear the long story:
I play League of Legends, Steam, Osu! on my Mac and it took alot of capacity (or space).
And League of Legends has thisthing called "Item sets" that when you save it, it doesnt save it in the client (or app), it saves the "item sets" data in your computer (took alot of capacity/space)
Not just that, and I had iPhoto but when i downloaded iLife to my mac, and after that, it said my iPhoto is damaged and it can't open.
And summer ended, my parents said If I fail my 11th grade, they are going to kick me out so I told them I'm going to reset my Mac to factory settings and get a fresh start, well this happened.

hi there! I got it back to work by buying the USB version of Mac OS X Lion 10.7
and since my internet connections are kinda bad, I'm not able to download and update it to 10.7.5.
but anyways I got it back to work.
All I can say is I suggest you to buy the USB version of Mac OS X Lion 10.7 from amazon or apple store.

Href and target tags tutorial/help needed for use with an existing website

I have a website, (built through iweb), and an intro movie. I have spent a lot of time trying to understand the proper tags and how to use them without much luck. My goal is to have the homepage associated with my domain name load in a browser while at the same time have my intro movie open in a Quicktime Player window, play, and automatically close leaving the webpage visible. If anyone can point me to a tutorial or walk my through the process I would appreciate it.

Poster movie style. Requires QuickTime Pro:
Create an image (or a frame from your movie). This becomes the "poster". You could add text to it (Click to Play) in a graphic editor app to help your viewers or add text to the page under the image with these instructions.
Save this new file as poster.mov
It becomes the src="poster.mov" (source tag in the html code). Set its dimensions to fit your page layout.
Your "intro movie" will be your href="intro.mov" (href tag in the html code).
Open it with QuickTime Pro and then open the Movie Properties window. Click on the Presentation tab to see the choices. Automatically close option will close the QuickTime window. Automatically quit option will quit the running QuickTime Player app. This would be a better option as the browser should come back as the "front" application. You also want to check "auto play".
Use Save As (preserves fast start feature) and name this file intro.mov
In your html code for the QuickTime files you need to set target="quicktimeplayer" (this launches the QuickTime Player app instead of using the browser plug-in). It may also help if you use the full URL to both files in each tag (http://myserver.com/foldername/intro.mov).
One of mine as an example. It uses automatically close window:
http://homepage.mac.com/kkirkster/mycareerfuture/
View the source code to see the tag structure. My page uses javascript instead of the older object/embed tag code.

USB PC to PC: help needed to use it.

I am having difficulties using the USB PC to PC file transfer between two computers. I installed USB PC to PC, latest version, on both computers and connected them via USB cable. I also made sure that the folders are set as "shared", and accessable by "everyone". I can see the other computer, from Windows Explorer, My Network Places, Entire Network, "Microsoft Windows Network", but when I try to "Map Network Drive" or log on to the other computer, I can not.
Please, help.

Yes, if the drive is formatted in Mac OS Extended (Journaled).
The USB port on the Time Capsule is under powered, so you may need use a powered USB hub with the 4 TB drive...even if it has its own power supply.

Help needed restricting users admin access to devices using ACS 4.2

I have users that access the network via a VPN client to a PIX 515 which authenticates to the ACS (using the default group for unknown users) which uses an external Active Directory Database.
The problem I have is that as the ACS authenticates these users, it now allows them admin access to the PIX. How do I restrict access? I have looked at NARs using the 'All AAA clients, *, *' approach but that just stops their VPN access. ( I have a separate group called 'PIX ACCESS' which will contained only defined users for admin access).
Incidentally I have other devices on the network which are AAA clients, in particular Nortel switches. I can set the group settings for that RADIUS set up to 'Authenticate Only' (RADIUS Nortel option) and that works fine, I was expecting the ACS to have a similar setting for TACACS+.
So how do I allow the unknown users to authenticate to their AD database but restrict them admin access to the AAA clients?

Very common problem. I've solved it twice over the last 6 years with ACS. I'm sketchy on the details. But here goes. First option to explore is using RADIUS for VPN access, then TACACS on all the Cisco switches and PIX firewall. That would make it alot easier. I think that with TACACS, you can build a NAR based on TCP port number instead of IP address....
http://www.cisco.com/en/US/products/sw/secursw/ps2086/products_tech_note09186a0080858d3c.shtml
So you'd have a group with 3-4 Administrators that can access PIX CLI, and another group of VPN users that can't access the PIX but can VPN in. So on the VPN group, put a NAR that restricts access to SSH/Telnet TCP ports?
This comes up everytime I install an ACS server, (every 2-3 years), and it's always a trick.
Please let me know if this works for you. And if it doesn't, let us know how you fixed it. I think I can get back into the ACS I last did this with and take a look, but I'd have to call up and make a special trip.

Help needed after "repairing" usb stick -16gb

Hi there,
currently have a problem with my Lexar usb stick, approx. 2 years old, 16gb stick. I went for the usual cleaning method of removing files, and checking sizes of folders etc one day, and then decided to check a folder, right clicked and went the usual "get info" ....it started to think...and then ejected the usb stick. Plugged it back in, and did the same thing...same result. So the third time i plugged it back in and decided to do a repair disk in Disk Utilities.
It ran its course, and then it ejected by itself, thinking it was done its job. okay....so i unplug it from the side of my Macbook Pro...running Snow Leopard...and then plugged it back in...and nothing came up...
Usually a little light on the usb stick lights up, but nothing happened....tried plugging it in a few times, nothing.
Tried a variety of PC computers....the only thing i can see is that the disk keeps ejecting itself from the device manager....but i cannot mount it or anything.
I need help, as there are crucial files on it.
Also, when I try to do a boot to windows from Mac, when you hold option/alt down, it thinks and keeps thinking but never shows the drive. ....assuming its dead...by why can windows at least see it, just not connect it as a drive.
Whenever I try running recovery programs it does not find it.
so again, I cannot do much, but would really like to just put it out there for anyone who has successfully taken care of these problems in the past.
Thank you for anyone who helps me out.
much appreciated.
I've tried running Linux as well, but not too familiar with it...as the usb stick does not even connect there either.

USB stick is Flash memory you should not delete files often, the only thing you should if you need to free space on it is FORMAT.
You can try and connect it, Disk Utility should see it. Do erase and use format FAT32.
If Disk Utility does not see it, try the same on a windows PC; if that does not work either... gone:

Desperate Help needed in using LabVIEW

Hi,
I'm a beginner in using LabView programming. Can anybody help with implementing Labview 6 and Keithley 2400 SourceMeter for data aquisition? I've wired up the hardware and have problem coming up with the software.. Any idea how to get started?

Hello giam,
I made wrapper vi's for the standard GPIB Read/Write functions to
handle errors (using green icons to distinguish them better). The "send
mult" handles simple strings (like standard GPIB Write) and array of
strings (you often need to send more than one string to a device). But
generally those icons have the same main functionality like standard
GPIB...
To send an array of strings you put the GPIB Write into a for loop and
connect the array as input with autoindexing enabled (as standard).
Maybe a small delay will help for some devices, the K2400 should do
without.
Edited: The greenish delay icon is just a standard "Wait ms" with
additional error cluster in/out to allow dataflow programming...

Help Needed in Fixing USB Printer after CUPS Update [SOLVED]

CUPS updated a while ago but I didn't notice any warnings from pacman or whatever. I did later notice on the front page that cups had been upgraded so that usblp is no longer usable. It told me to blacklist usblp, and so I did. I also upgraded the /etc/cups/cupsd.conf file as per the instructions.
I still cannot print.
When I plug in my printer, I get the following in /var/log/messages.log:
kernel: usb 5-1: new full speed USB device using uhci_hcd and address 2
kernel: usb 5-1: configuration #1 chosen from 1 choice
load-modules.sh: Not loading module 'usblp' for alias 'usb:v03F0p1D17d0100dc00dsc00dp00ic07isc01ip03' because it is blacklisted
Any help would be greatly appreciated.

Luckily, I have printing working by readding the printer.

Using USB 2.0 devices

Hi, I've got an eMac 1 GHz with Firewire but only USB 1.1. I would like to use a Miglia TV USB-key to watch numeric-TV but it doesn't want to work, because it needs USB 2.0.
So one question : would it be possible to use the firewire port through an USB to Firewire cable, or a Firewire Hub with USB ports such as this one :
http://www.lacie.com/download/qig/hub.pdf
Thanks

Sadly, no. Combo USB/Firewire hubs are separate USB and Firewire hubs in the same chassis with the same power supply; there's no data conversion from one to the other. There have been misleading advertisements for "USB/Firewire cables"; read the fine print, and those things are double-headed cables that can be used with USB or Firewire, but not both at the same time. There reamins as far as anyone herabouts knows no way to adapt Firewire to USB 2.0; if there were, owners of pre-USB 2.0 Macs would be snapping such devices up to use with current generation iPods.

Lumia will not Sync wurelessly, need to use USB ca...

Hi all,
Trying to sync my phone to pc wirelessly but have to keep plugging in UDB cable.
The phone is connected to wireless network and I was told that you need to plug in once to activate wireless sync, but does still not work!!!
Thanks for any help you can give
Simon

PC and phone need to be on the same subnet, most likely they are unless you are using more than one router.
Zune needs to be running on the PC and you have to enabled Wireless sync.
You may need to check that windows filewall is configured to allow Zune to access the phone.
Finally phone has to be plugged into a charger/powered USB port for sync to start.

Help needed in using oracle rules SDK

Hi,
For testing my rulesets using oracle rules SDK I doing the following:
1. Creation of dictionary, ruleSet.
2. Declared two kinds of globalVariable variables in my datamodel :
Final and non-Final.(Type of these varaibles are String and Double only)
3. Final globalVaraibles are used in creating rule's patterns.
4. Non-Final globalVariables are used in creating rule's action.
5. Functions are created for asserting globalVariables values and
returning non-final varaibles, since those are required as action
results.
6. In java code I am testing my ruleset (dict.testRuleSet()). Before
testing i am populating my final global variables (since these are used
in rule's patterns),
and updating datamodel.
The above procedure is working fine and I rules are successfully working.
Now, first of all i want to know if the above mentioned approach is correct or it needs to be reframed??
secondly, when i update datamodel with values (in java code itself) it
takes 4-5 seconds in updating it. This is the main issue that why it is
taking this much time??
any comment would be of great help.
Thanks in advance.

I will send up an alert for you, Colin. Even though I use iTunes for Mac, troubleshooting it isn't my forté.
