The easiest way to get started with serial port communication in LabVIEW is to example program.  If you are using LabVIEW 7, click on "Find Examples..." under the Help menu.  Under the folder "Hardware Input and Output" there is a sub-folder called "Serial".  Open the "Basic Serial Write and Read.vi"  Set the proper COM port settings with the inputs on the left hand side.  Use the toggle switchs to select the READ or WRITE function.  Run the VI.  Once you get comfortable using this VI manually, you can call it as a subroutine in your own applications.

That is a pretty cool project.   In general, your parallel port is an open collector device.  So it's Open Circuit when active.   A simple 20K pullup should convert it to an accepable digital level.   \n\nDepending on the language, and computer configuration, the Output command from C++ will work, once that port is enabled for WRITE.   You've got to check the manual on this; as it related to your printer port.   For Windows, you may have to disable the LPT1 port for normal operations.   I did this many years ago under DOS.

It is very simple. Write these codes:\n\nchar byte = 0xff;\noutportb( 0x378, byte );\n\nbyte is something you want to see in the output port. It is a character. The above code outputs 1's in the pins 1 - 8 of printer port.

Just burn it as a data cd. It should be fine you should be able to re-install it from the disk you make. Also put a word file with the serial if it required a serial # to install a full version on the cd as well. Thanks

I have some c++ serial port code that does what you want. Email me and I will send it to you. I have used it for a few apps. and it seems to work just fine.

I recommend Shields Up! It's a great (free) online port scanner:\nhttp://www.grc.com/x/ne.dll?rh1dkyd2\n\nAnother free online port scanner you can use is the Sygate Online Scanner:\nhttp://scan.sygatetech.com/probe.html

Use DVDX:\n\nhttp://www.labdv.com/dvdx/\n\nYou can download version 2.3, which is free of charge.

you need a null modem cable.\n\n\nlike a parralell to parralell or serial to serial  then use the direct cable connection tool to connect.\n\nMust be running on both machines.. one running as host one running as client.\n\n\nhope that helps

Just purchase one USB to LPT convertor cable which is available in the market. That cable has one end USB pin and the other end it has LPT connector. After that connect your scanner using parallel port cable 25-pin female (which are also used for printer sharing switches) . Good luck

Buy a USB cable.\nload the driver.

You need a data acquisition board to "talk" with the analog input and transfer to digital signal. LabVIEW program can communicate with the data acquisition board to read the input and store in PC. Then you may import the stored data into Excel for various processing.

Use MRTG. It will give you nice graphs on various ports. See http://oss.oetiker.ch/mrtg/\n\nYou can also get Windows based version if you do not have unix boxes.
