For DIFF or NRSE analog input what is the "R ext" that is needed for grond?

I am trying to input a 0-10v signal to my daqpad-6016. A resistor indicated as an R ext is required between the AI- or AI SENSE and AI GND. What type of resistor is this and how do I determine it's value?
Thanks!

The value is not critical. I generally use 10K.
This resistor is used to avoid the drift of the signal due to the input bias current of the DAQ card.

Hi All,
Please advise me What are the essential services that are required for ensuring server is healthy up ?
Warm regards,

The easiest way to find the Health report of server or workstation follow the below steps which is very much easiest way to get it done
There are a few ways to find this in Windows Server 2008.
First click “Start” and type “Generate a system health report”
Or second navigate your way to the Control Panel choose “System and Security” and choose “Generate a system health report”.
The last is to type “Generate a system health report” into the “Search Control Panel” box in the upper right hand corner of the Control Panel window.
Once armed with this data it’s easier to refute or acknowledge an issue is at hand.
BTW if you’re looking for this same thing in Windows 7 it’s there just buried a bit more.
Search Performance in the Start Menu, choose “Performance Information and Tools”, click “Advanced Tools” from the menu on the left, and finally choose “Generate a system
health report”.

I cannot sync my iphone to my macbook since the highest software upgrade on it is 10.5.8. I cannot upgrade to the min. software necessary to upgrade to the itunes version that I need for the iphone 5! Please help!

I cannot sync my iphone to my macbook since the highest software upgrade on it is 10.5.8. I cannot upgrade to the min. software necessary to upgrade to the itunes version that I need for the iphone 5! Please help!

The iPhone 5 requires iTunes 10.7 or later and iTunes 10.7 requires OS X Snow Leopard (10.6.8). If your profile is correct it looks like you need to update your OS X on you Mac. You can contact Apple and purchase the software from them.

Re-installed Windows 7/iTunes 10.7. iTunes sees my iPhone 3gs. Won't sync. I have back ups to the cloud and my computer but moved my music folder. How do I resync with a backup??? What's the file called that I need?

What is the name of the file I need to resync back to what I had before I reinstalled Windows7/Itunes?
I don't want to lose all of my apps. iTunes does see the phone but either has miscalcuated and told me I'm over
the size of my allocated sizes for music/apps, but when I uncheck, it still won't sync.
Best way, I assume is to go back to the last backup. So help me out here, what are the file (s) I need and
where are they best stored? I have all my music now on my J drive, not my C drive.
Can anyone help me?
Thanks,
Sue

I backed up to the iCloud and to my computer. Only thing I seem to be missing is a couple playlists. I just didn't want to lose my paid apps.
So what I see in my music folder and then another folder called iTunes and then files like iTunes Library, iTunes Library extras, iTunes Music Library aren't anything that is a back up, I take it, since you said the back up would be under programs? If this statement is true, now I "get" it!
And just to be clear, in iTunes, in my apps, there are all the apps I have gotten for free or paid for. But the problem there was that the Sync was grayed out and if I check it, everything goes crazy with saying I don't have enough room. I unchecked the music folder, and still had problems.
Oh, I hate this part of the iPhone stuff!

I am trying to translate the labview program to a real time labview programming....i wan to know what te the main isse that i need to focus on

currently i am doing a lift monitoring system which made use of labview. Due to time constraint, i have decided to use the real time labview program. However i have no prior experience on the real time programmng, can i be enlighten on the main issue and what are the thing i ned to look out for. is thre any documentation that i can use?

Derek,
Programming for LabVIEW Real-Time is very similar to programming for LabVIEW for Windows. Many VIs do not need to be changed in order to run in LabVIEW Real-Time RT Engines. However, here are some issues to consider:
1) Drivers
2) File I/O
3) Dialog Boxes
4) Shared resources
1) Drivers. If you application was written in LabVIEW for Windows, and then ported to run on an RT Engine on RT Series Hardware, you need to be sure that the drivers you are using are supported on your platform. See KB 28G97MZ8: http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/aad11f924e5b5fd086256a310053a094?OpenDocument
2) File I/O: If you are running your programs on an RT Series DAQ Device, it has no storage device, so file I/O operations will crash. See KB 26FBO0KN:
http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/3c35f5e85476579d862569f50067462e?OpenDocument
File I/O on RT PXI Controllers is supported in 8.3 filename format (no spaces in the filename allowed).
3) When your application is deployed, (Operate>Download Application, Operate>Run, then File>Exit without closing RT Engine VIs), you VIs continue to run. However, the RT Engine runs headless with no keyboard, monitor (limited information displayed), or mouse, so any user interaction previously required by your VIs, such as Dialog boxes, will hang or crash your program. For user interaction with a deployed application, communicate to the Host PC using shared memory, VI Server, TCP/IP, DataSocket, or UDP. See ~\labview\examples\rt\rt communication.llb for examples.
4) Even though your programs now run in a real-time operating system, you need to follow good real-time programming techniques. These include: using multithreading with critical tasks set to time critical priority. One time critical VI with no parallel loops. Avoid accessing or using shared resources in time crital VI (shared resources cause jitter). Shared resources include the memory manager (preallocate arrays used in time critical loops), global variables for interthread communcation (use RT Queues). For more information, visit the LabVIEW Real-Time Resource Library in the Developer Zone: http://zone.ni.com/devzone/devzone.nsf/webproducts/c25f8c664230613a862567df006abb06?opendocument

T23 - What are the plastic side rails & adapter needed for drives to fit in the Ultrabay?

Does anyone know the part numbers for the plastic side rails and adapter required to be attached to a bare CD or DVD drive in order for it to fit in the Ultrabay and connect? I have a bare Sony DVD RW replacement drive with the correct "notched" bezel. I know most people just strip off the adapter and plastic side rails from an existing IBM/Lenovo Thinkpad CD drive and put them on the new drive. But I was wanting a second set to I could keep both the T23's (a 2647) DVD CDR original drive and the new DVD RW drive.
Life is just one big "Beta Test"
Happy owner of a T43 (Windows 7) and T23 (Windows XP)

I've never run into part numbers (i.e., FRU) for the Ultrabay rails and I've changed out my fair share of them. What I basically do is buy "dead" or "parts" optical drives off of eBay and then scavenge the rails and IDE connector. I believe that there are at least two very slightly different designs; the thickness of the side rails is what changes. It's never gotten to the point where the re-fitted drive doesn't fit into the Ultrabay but, depending on the drive and rails in question, there may be too much or too little space inside the bay. Also, you should be careful when transferring screws from one drive to another. I've found that on some drives, if the rear screws (the ones which hold the connector on the back of the drive) are slightly too long, then that can prevent the tray from closing.

What is the serial number that I need to install this new photoshop product I just bought?

I need help. I purchased a new Adobe photoshop elements 11 from Best Buy and I have all the boxes. I try and install this using the numbers on the back of the inner liner but it keeps saying invalid serial number go back and try again. What am I doing wrong???? JIM

When I bought PSE11 at Best Buy, I think that number on the back of the box (a boxid lets call it) is something that has to be entered into a website to get the serial number. The instructions, Including any website, should all be there if you have all what was in the box.
Best Buy transmits what boxids have been sold in real-time to Adobe from the cash-register, and Adobe checks the boxid you enter into the website with the list of actual sold boxes they’ve gotten from Best Buy, before they will issue the serial number.

What edition of Oracle DB do I need for Map Viewer 12c?

Hi All,
What edition of Oracle DB do I need for Map Viewer 12c?
Thanks,

What version of Oracle client do I need for a machine with Windows 8?
Windows 8 doesn't require ANY version of Oracle client!
Most installations of Windows 8 never install Oracle client and they have never had any problem except the large set of problems that come included with the OS itself (bugs).
So you clearly need to explain what PROBLEM you are trying to solve.
Then we can help you find the best way to solve it. For example you could download and use the free Oracle Sql Developer and just use JDBC to connect to your databases. Then you don't need an Oracle client at all.

What is the minimum file system access needed to run ODI 10.1.3.4.0 client?

Hi ODI discussion folks,
I have a couple of questions from an Oracle partner that I'm trying to find a definitive answer for if possible. The partner is setting up ODI 10.1.3.4.0 for a customer who insists that the absolute minimum amount of access to the file system is granted due to corporate security policies.
I have checked the bundled ODI documentation but couldn't really find anything about file system permissions needed to run the ODI client. I was pointed towards the "Setting Up Security for an Integration Project — What to Consider" document but this does not mention a great deal about how much access to the file system is needed for the ODI client to function.
What the partner is asking is the following:
"1. What are the minimum file/folder permissions needed for the ODI client installation? I'm installing at xxxxx
and their machines have to be locked down as much as possible.
2. Say you have 3 users all wanting to run integrations etc and the Master and Work
repositories have been set up. An admin installs the ODI client but doesn't
create the connection to the Master repository. What are the minimum
file/folder permissions required on the client machine to:
a) create the connection to the repository
b) run any subsequent integrations?"
If anyone can advise on this then that would be much appreciated.
Regards

Hi Craig,
How are you?
Let me try to contribute a little....
1) The minimum requirement is for its own installation directory, there is no reason to have access to other directories unless if it is necessary to read files from some other directory at the client
2) Again only to its own install directory. The connection setting is recorded at \bin install directory. After that, all information are recorded at repository, there is no client work.
Be free to contact me by email or phone if you have any new doubt. You can get my email from my profile.
Does it respond your doubts?

What is the best way to format Videos for ipod touch?

What is the best way to format Videos for ipod touch? Used Quicktime Pro/ Export (iPhone setting). Videos aren't as crisp as downloaded Videos. Compressors /ipod video Setting also looks crapy (with bitrate med & High). What should I use?

Visualhub is a transcoder with multiple input and output formats with specific setting for iPod,iPod touch. Costs around $19-used to work great but recently everything I convert suffers audio crash than closes out the player. Hopefully they will fix it.
Elgato H.264 hardware transcoder is $99 dollars(USB stick that plugs in to Mac)-speeds up encoding of any file quicktime can handle, settings for apple tv, iphone/touch, ipod,Sony PSP. Worth the cost if you transcode a lot of video for the Touch or own an elgato HD tuner. Files work flawlessly and look great.
Mpeg streamclip-free. Works great, has presets or can customize the output.

What is the best malwear detection and protection for use on a Mac?

What is the best malwear detection and protection for use on a Mac?

Mac users often ask whether they should install "anti-virus" software. The answer usually given on ASC is "no." The answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to log in to it remotely. That threat is in a different category, and there's no easy way to defend against it.
The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has so far failed to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. These failures don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is foremost a problem of human behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software.
☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the left side of the address bar when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" (AV) or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It's as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

How to use both digital and analog input modules in the same worksheet - MCC USB1208LS

Dear all,
Hi, I am Imran. I am using MCC USB1208LS. I have created the worksheet using digital input module as below and able to execute (run).
But when i add another analog input module in the same worksheet and executes, An error Message pops-up as in the below image
I have connected temperature sensor sognal to the analog input of USB1208LS. When using analog input alone in the worksheet, it indiates the actual values.
is any black box solve? please guide me. I am attaching in images
We already placed a purchase order for USB1208FS. Will it sort out my issues?.
Thanking you,
Imran Mohamed.

Hello Imran,
the USB-1208LS is not capable of running concurrent operations such as an analog input scan and ANY digital Ins, Outs, counter reads, or analog outs. In Dasylab, the 1208LS is scanning, and nothing else from that particular device can be requested of it while that is happening.
Yes, using the 1208FS will resolve some of these issues.
Please refer to the ULHELP.CHM file installed on your computer in c:\program files\measurement computing\daq for details on this issue, et al.
also I recommend you send your MCC/DASYLab requests for support to [email protected] as MCC staff (that includes me) does not normally monitor NI's Developer Zone.

What is the best I/O to use for a MUD?

What is the best I/O to use for a MUD?
It seems that people usually show I/O examples with IOs like:
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInptuStream()));
PrintWriter out = new PrintWriter(socket.getOutputStream());
out.println("Hello World");
out.flush();
PrintStream out = new PrintStream(socket.getOutputStream());
out.println("Hello World");
out.flush();When I say 'best I/O' I mean, can you give me an I/O that'll be the best if a MUD starts getting LOTS of request and becomes rather busy?
Thanks!

One last question, are output streams thread safe?A stream is inherently serial in the way it data is written to it. If two threads try to write to the same stream asynchronously, the ordering of the data written will not be predictable.
For example:
One class is recieving input from a user and
reply-printing thing like "Command Successful", and
another class is recieving messages from other users,
but the PrintWriter would be originally created in the
first class and then passed as a parameter to the
second class...would this work, or should I just
redirect all command replies to that second class?If they are in the same thread, then it could work. If there are separate threads, then some higher granularity synchronization needs to be imposed, so that the second thread doesn't start writing part way through the first's output.
For example:public class NeoThreadWriter implements Runnable {
final String name;
final int delay;
final boolean synch;
NeoThreadWriter (String name, int delay, boolean synch) {
    this.name = name;
    this.delay = delay;
    this.synch = synch;
public void run () {
    if (synch) {
      new Synch().run();
    } else {
      new ASynch().run();
class Synch implements Runnable {
    public synchronized void run () {
      synchronized (System.out) {
        for (int i=0; i<6; i++) {
          System.out.println(name+":"+i);
          try {
            Thread.sleep(delay);
          } catch (InterruptedException iex) {
            iex.printStackTrace();
class ASynch implements Runnable {
    public synchronized void run () {
      for (int i=0; i<6; i++) {
        System.out.println(name+":"+i);
        try {
          Thread.sleep(delay);
        } catch (InterruptedException iex) {
          iex.printStackTrace();
public static void main (String[] args) {
    try {
      Thread threadA = new Thread (new NeoThreadWriter ("A", 40, false));
      Thread threadB = new Thread (new NeoThreadWriter ("B", 20, false));
      System.out.println("asynchronous threads");
      threadA.start();
      threadB.start();
      threadA.join();
      threadB.join();
      System.out.println("synchronized threads");
      Thread threadC = new Thread (new NeoThreadWriter ("C", 40, true));
      Thread threadD = new Thread (new NeoThreadWriter ("D", 30, true));
      threadC.start();
      threadD.start();
      threadC.join();
      threadD.join();
      System.out.println("Done");
    } catch (InterruptedException iex) {
      iex.printStackTrace();
}With asynchronous threads A and B, the output is all mixed up. With synchronized threads the ordering of the output is maintained. Note that the guard has to encompass all of the code that generates the output; simply synchronizing the println invocations wouldn't prevent the mixing.

For DIFF or NRSE analog input what is the "R ext" that is needed for grond?
