Could you help me to control a DC motor with the parallel port and windows 2000?

I have labview 5.1 and i want to control my application throught the internet

I would recommend upgrading to LabVIEW 7.0 for a couple of reasons. First, LabVIEW 6.1 introduced remote front panels which allows you to control a VI through a web browser. Setting up remote front panels is very simple and that alone is worth the upgrade. As far a using the parallel port you can use VISA to send/receive commands via the parellel port if you are using a motor controller with a parellel interface. If you are talking about using the port on a bit level to control the motor, LabVIEW 7.0 ships which an example of how to do basic digital input output with the parallel port.

How to communicate two PC's with the serial port with Netbeans

Do you know how to do it?
Do you know how to communicate with the parallel port too?
Could you give some ideas?
What commands or instructions I have to use?

What does NetBeans have to do with it?
All these "people" today that start out in Java using all these "nifty" IDE's. All it does is produce exactly this. They think their IDE is Java. Once they no longer have their one specific IDE in front of them, they can no longer function. They have no idea what the classpath, what the compiler actually does, how to package a jarfile, hell, most of the time, they don't even know how to execute a simple application.
As far as your question. Did you even try to Google for some Serial port API package? Assuming you did, did you download it and read the documentation that comes with it? Did you search for a few examples on the web? Did you read them? Did you try them? I can almost guarantee that the answer to everyone of those questions is "no". So, my question for you is, "Why should we help you?" You obviously have no desire to help yourself, so I think we should reciprocate in kind. Don't you?

How can I use the parallel port as an input channel to communicate with a SPECTROMETER?

Hello,
The sensing system we use is called: FieldSpec Pro from www.asdi.com.
The spectrometer has a LPT terminal. I'd like to use LabVIEW to acquire signals from the spectrometer for further analysis.
Thank you!

Dennis,
I appreciate your time.
I have asked the copmany for such infos, but it seems to be confidential.
Do I need an I/O DAQ-Card?

About all that tells me is
that I'm located in the same town as the manufacturer. You'll need to
find some specification that describes the parallel port protocol.
Without that, you're just wasting your time. Even if the instrument is
constantly sending data, you'll need to know how to interpret the data
and there's nothing that says it has to be sending constantly. Maybe
you first have to write something to the port first. Talk to them and
tell them you want to replace their software with software of your own
and need to be able to read the data.

Is it possible to control the parallel port with Lookout 5.0

I want a simple demo setup on a PC, so I can control the 8 data bits of the parallel port. Example, to use START p/b that would toggle bit 0 and data returned on bit 1.

It is possible to send bytes to the parallel port using the ASCII object within Lookout. However, it is presently not possible to control the state of the individual bits on the parallel port with Lookout.
If you need to control the individual bits on a parallel port, consider using LabVIEW. It is much more powerful when programming serial and parallel ports.

My opatical equipment measures the brightness with using the parallel port.

How can I receive that data ? Plz...send me ur advices through e-mail.

Hello,
You should probably be a bit more specific in your problem description. Please post your question in the software category that pertains to your application. For instance, if you are using LabVIEW to communicate with your parallel port, you may want to post your question in one of the LabVIEW categories.
Good luck with your application.

How can i us the parallel port of the printer to control a frequenz-generator?

Hello all !
I like to control with LabVIEW 8 student-version, the Frequenz-generator gadget . For this challenge i like to us the parallel port of the printer. I need for data flow only 2 cable. The frequenz-generator gadget need two signal : Low and High.How can i us the parallel port of the printer to control a frequenz-generator gadget? I have us the VIs-Visa (Visa-Serial, write, Close ), but i dont no what command i have to write on the Visa-Write so that the Signal can be in the low or high position.
Thanks

Hi Jeanjac,
first, look here:
http://en.wikipedia.org/wiki/Parallel_port
to get the port numbering. also, be sure not to leave pin unconected, sometimes you might get an error message otherwise (i remember pin11 has to be always connected or so for windows...)
second, just run the test panel in MAX and write something to your device to check if it works.
then in LV, you have to decide to which pin is connected your instrument. in any case you have to address all 8 output pins together! this is a parallel...
if you prefere to use only one pin, then you can use the serial port, with just pin 2 and 3 connected. it would work easier for you, since you address only one bit.

Using stand alone executables to send data to the parallel port

I have a executable that uses the parallel port to activate an alarm. The program works well on the base machine which is running windows XP. However when I try to run the stand alone executable on a windows NT machine there is nothing sent to the parallel port. I have updated the Cvirt file on all machines. I don't get any error messages when running the stand alone executable.

I have the same situation using parallel port to control a hot swap PCI extender card and no error showed. I can turn on/off and read correct voltages from the card in base machine. After creating executables, I can turn on/off the card, but got wrong voltages in target machine.
I've installed AccessHW in both machines and copied AccessHW.dll and cvirte.dll to system32 folder and the folder same with executables. I also tried installer with port support and serial support checked.
Windows XP is in both machines and LV 7 in base machine. I use "Output Byte to Port.vi" and "Input Byte from Port.vi" in AccessHW lib.
One thing I observe is initiation. The card manufacturer provides a program with same functions. After running their program, the voltage readings from the executables become correct. The readings remain good after closing their program. I close the executables and run the executables again and still see good results unless restarting the target machine.
Any solution for the problem? Thanks in advance!

How can I write to the parallel port using LabVIEW 6.0.2

I have tried updating the labview.ini file and also using the parallel.llb available on the site. When I execute the program it gives me error 37 saying,"device not found". I am running this code on windows 98. I tried to use VISA write,serial port write (using port 10) but nothing seems to work. I also tried to develop a sample code using inPort and outPort, but no success, it is not able to read the data back from the parallel port, even if it seems (????i don't know any way to cross-check it though????) to write.
Does anybody know the problem here?
THanks.
Pari.

Thanks Brian.
Well here is the next problem. I got a VI (attatched) off ni.com and it works fine on a windows98 platform. But quits working on NT.
I can write perfectly (which i checked by hooking an LED display unit at the other end of the parallel port cable). I observed that the LEDs respond to the toggling of individual bits (data bits). But the error occures at the "out port.vi", when I try to run it on a NT machine (where I actually wanna use it). Are you aware of any changes to be made in order to run a VI on NT that works on 98?
Thanks again.
Pari.

Using XP software with a parallel port dongle in windows 7 professional

Please help... Looking to have my parallel port dongle recognized for my older version software (XP) in Windows 7 under the XP PC mode. Help in figuring out if LPT1 is set correctly or what I am doing wrong.
Thanks

Hello,
I have W7 Professional 64 bit with Windows Virtual PC/Windows XP Mode installed. I have some older programs installed in XP Mode and they are working properly.
Unfortunately, I have one older program that I currently have working on an older XP Machine and that program requires a Sentinel dongle to be seen on the LPT1 Parallel Port. Since my W7 computer has an LPT1 Header on the mother board, I have purchased and
installed a PCI-Express Parallel Port and I have the ribbon cable connected to the LPT1 Header.
After I enabled the parallel port in the bios, I could see LPT1 in the W7 Device Manager and in the Windows XP Mode Device Manager. However, when I click on
Windows Virtual PC, highlight Windows XP Mode.vmcx and click on Settings, LPT1 does not appear.
I have installed my old program in Windows XP Mode and it starts to run but, when it gets to the point where it must see the Sentinel dongle on the LPT1, the
program does not find the dongle.
I also purchased a Manhattan MHUSB to DB25 Parallel Converter and plugged it in. It said that it found new hardware and installed drivers for it but that didn’t
work either.
I am not married to any particular solution. So, I would use a USB Adapter or LPT1 connected to the mother board but there must be some code editing or changes
in settings to make the dongle work in XP Mode.
Can you tell me how to get W7 Professional 64 bit with Windows Virtual PC/Windows XP Mode to find the Sentinel dongle
on LPT1?
Thank you,
Dan

"Error [10151] The LCP Port on CCM Admin for Mobile Agent is not Configured or misconfigured"

We are running into a problem which we have noticed on UCCE 8.5 and havent seen on earlier 7.5 release.
If we setup a CTI port as agent device target and if we try to login the agent using Cisco Desktop (Not CAD, just CTI OS Client) then we get following error:
"Error [10151] The LCP Port on CCM Admin for Mobile Agent is not Configured or misconfigured"
But this wasnt the issue with 7.5 and we were able to do agent login with CTI Port as device target. We dont intend to use Mobile Agent feature but just login UCCE agent to CTI port as the device.
Do we know if this is a known issue or if something has changed between 7.x and 8.x release which could be is causing this?

So you can ping and nslookup from your ms to these agents and vice versa right? I wouldn't do a manual install, I would push the agent from the management server. You can uninstall the agent manually, or use cleanmom to get rid of them. Then
do an install from the console. When you initiate the install from the console (management server), should it run into any issues it will dump out an error which will give you an idea of where the problem may be.

Why does this loop used to write values to the parallel port keep going forever?

Have a look at this VI guys. I'm trying to send a sequence of bits (used to trigger an IC). I'm interested in the last bit of the data port (D0). so I'm sending either 0 or 1 to that pin to trigger the IC. it works, but the problem is that the loop keeps going forever and i cant control it. if i send 3 to the loop count, I'm expecting to get: 1 0 1 0 1 0, but it doesnt stop and keeps going forever.
It seems that the problem is not with the loop. because i deleted the loop and just left the flat sequence so that it executes only once, but still it keeps repeating. How can i make the flat sequence execute only once?
I'm using a parallel port monitor (parmon.exe) and a LED connected to D0 of the parallel port to check.
If anybody has an alternative or better method to send the bits to the parallel port, I'd be very thankful.Message Edited by krayzie on 05-14-2005 04:33 PM

It works just fine here. Place an indicator to the iteration terminal [i] to watch how things progress. Do the number ever increase above N-1 to what you wire to N? I don't think so!
Also make sure you don't run the VI with the "Continuous run" button. In this case the VI would immediately restart whenever it is finished. use the "Run" button.

Writing a String to the Parallel Port

I am a new user of Labview and have very little experience. I am trying
to write an arbitrary string (that I can input) to the parallel port.
Basically, I need to communicate with a device that connects to it and
will accept commands as plain strings. I have read the article "using
the parallel port with labview" but it hasn't helped me as I am so
inexperienced. I was hoping that someone could help to learn how to do
this and if there's a vi that already does this. It seems like a simple
enough task. Thanks.

Rather than simply present an answer from which you will learn little, I will try and out line what it is that you should investigate......
First have a look at a string control
You might want a button and a case structure to tell the code when to start decoding the string
Put the following code inside the case structure say on the true state
Then, taking data from this string control get the strings length
Then using this and a loop index through the string using the string subset VI on the string pallette, use the length of 1 and index the position in the loop
Now figure out how to convert the character to an ASCII value
Send this to the parallel port
This should be a reasonable frame work to empower you to learn for yourself.

Problems with the USB Ports

Hi there,
I writing this because I'm having some really big problems with my USB ports.
A few days ago I plugged in an USB-Hub that was quite cheap. Suddenly a window popped up saying that a USB device was deactivated because it "needed" to much power. Since this happening, two of those windows keep popping up everytime I boot the MacBook. I called Apple and got some help: I had to delete some .plist files and clear some caches. The man who helped was able to find the error and deactivate the notification, he also told me to make a PRAM- and a SMC-reset. The man said that it's just a software problem and that I have to reinstall the system if we don't find a solution. So, one day later I reinstalled the system (Lion) and not only didn't it help, the two notification windows were popping up again...everytime I booted the Mac. So I decided to formate the whole hard drive and install Snow Leopard -> still the problem with the USB ports. After that I installed Lion -> still the problem with the USB ports. I even tried to extract the .kext files that are important for the USB functionality from an earlier Combo Update, but it didn't help either. The point is, that the Mac doesn't recognize my external hard drive or any of my iDevices. Sometimes it recognizes USB sticks, but only after 20 seconds. The data transfer on both USB ports is also very slow. If I'm lucky and Mac recognizes one of my USB sticks, it takes like an hour for 1GB to be transfered on the USB stick or from the USB sticks to the Mac.
I really don't know what to do and need help, especially because my backup data is on my external hard drive which I can't access because of this problem.
I really hope that someone can help me, I'm very thankful for every answer that could help me!
PS: Sorry for my bad English, I hope that everyone understands what I mean, please tell me if you don't get what I'm trying to explain in the text above.
Sincerely,
iLoud
[UPDATE] I downloaded "USB Prober" and copied the Output file, maybe it helps:
