• LabVIEW and parallel port

  I'm trying to control a motor of OMHT23-400 with a motor drive 3540 M using a Moschip PCI Parallel Port. I created a program to send impulses alternatilng the engine and make it run a desired amount of degrees. The motor in my computer address is/o series BD00-BD07. The same program worked in another computer that has address of the parallel port was Beach e/s-0378-037F. I don't know why, the program operates in the first computer and the same program will not work in this one. Thank you for your help.

• parallel port of LabVIEW

  I would like to write to a data generator circuit connected to a parallel port.

  Is there a driver for parallel port in labview on windows xp?

  Examples see LabVIEW 5 only if you are using LabVIEW version 5.

  If you are really using LabVIEW 8.2, you should have the example called Parallel Port and loop to write. There is nothing in this VI which refers to older versions of LabVIEW and the only restriction is that he cannot run on Vista.

• Press the button on parallel port signal to trigger a process

  I just need to connect a pushbutton on the parallel port to set it as a signal of the beginning of a process.

  When the button is pressed, labview runs a process.

  Kindly help me how to do this, the prayer of wiring

  Lines of data to use as input Some parallel ports can be configured for use as inputs data lines. This depends a lot on how the manufacturer has designed the parallel port. With some models the data lines can be read in the same way that we read the lines of control, leading them to logic high, so they will take the value of an external signal. However, most parallel ports require that you set the bit of sense for entry. It is bit 5 of the control register (base + 2). If the port is capable of it, setting the high bit for effect to sort of lines-State so it can be driven on the outside. Sometimes it is also necessary activate the 6 bit high or low. However, it is noted that some manufacturers actually block those bits so that the software can edit them. An example is shown below in Figure 7.

• parallel port does not have the protection key

  I just bought a terca M2. When I try to install a software that uses a hardware key (small connector in the parallel port) I get the message that he found no protection key. I have installed this software on other laptops (also with xp pro) and they are all worked well.
  I also tried two parallel port settings, but it still does not work.

  Please help me solve this problem, otherwise, this laptop will be useless to me.

  Hi robert,.

  have you checked that the chip set driver in Device Manager? As far as I know the parallel port is controlled by the entire ship!

  Have you checked if the parallel port in your M2 works without any problem (for example, a parallel printer) to exclude a defect of material! If there is a material defects you might bring the laptop to a Toshiba service for a short health check partner!

• Parallel port has stopped working on my A30

  I have an A30 with Win XP pro sp2. Recently disappeared from my DVD player and also my printer has stopped working. I reinstalled DVD Tosh tools and it is now working again, but I am unable to get the parallel port works again. I have it active in the Bios (worm 180.) and also in the control panel. He started to drive me crazy.
  Is there a tool to test the Lpt1 port or someone else has found a solution to this problem?

  Hello

  If does not work reinstall the drivers, I think you should try to recover the entire system. But don't forget to backup your important data. Sorry I can't give you better advice.

  Good bye

• The use of pins of status (4 outputs) and data (8 entries) of the parallel port pins at the same time.

  Hi all

  I'm a newbee in labview. As part of my project work, I need to get 8 digital inputs and send 4 digital outputs.so I think to use the Parallel Port on the pc.i can make use of 8 datalines for entries. I found the site NOR is it possible to use status for output pins. But is it possible to use status for output pins pins and data for entries to the time.please help even me also mention of the measures to take, or keep in mind while implementing.also include any example vi that could be useful.

  Thanks in advance

  I would recommed you to NOT use the parallel port. Now a day you have hardly a PC with parallel port. also if you have some old PC then most likely last version of LabVIEW (e.g. 2010) will need a lot more memory RAM and processor.

  If you want a solution very very low cost then I would recommend using an arduino to that effect. You can then download LabVIEW Interface for Arduino and start working.

  If you continue to use the parallel port, then you could try (I haven't worked with parallel port and have not tested the following solutions)

  Download VIPM and then install the enclosed package. It will add the port e/s palette in your labview. and you can use it.

• to detect the meter output via the parallel port

  I need to detect the meter count trigger, to perform an operation every time. I think passing the input signal pins (pins of status or control). The meter uses is omron H7EC.

  I lowered the voltage of 24 V to 5 v with resistors.

  But I can't get the entry via the parallel port.

  All the stems of my status are still high.

  What should I do, please help.

  In the parallel reading write loop.VI, the splash screen is attached.

  I suspect the entries on the parallel port pins have a resistance low pullup to 5V, so they tend to float high (logic 1).

  Try to add a 4 700 Ohm resistor between pins of entry and mass of the parallel port, see if it then reads down pulldown (logic 0). If so, then keep the resistance in place and connect the signal of 5V that you want to monitor at the entrance.

• Parallel port on Windows 7?

  Hi all

  I'm trying to migrate some older software (LV and otherwise - all internal written anyway) who communicates via the parallel port on a Windows 7 (64-bit).  The GPIB based programs all work fine, but I can't find a way to talk to the parallel port.  The machine (HP Pavillion Elite) came without a parallel port, but I found a card PCIe (Startech PEX1P) which adds the value 1.  It appears in the Windows Device Manager, but the address of the resource is listed as D010 rather than the old 378, and it cannot be reconfigured (the folks at Startech says Windows actually assigns the address).   Any suggestions?  Anyone try this yet?

  Thank you

  Michael Tracy

  Synergy microwave

  I know this is not guaranteed, but following the actual signs, I (finally!) got the Startech PEX1P card to operate!  Instead of using the Port.VI, I tried to use VISA you writing again, but this time, I updated the land of terminals 11 and 12 by the document OR on the use of the Parallel Port in LabVIEW.

  Michael

  Dennis Knutson says:
  Even functions in new versions of LabVIEW with the correct representation for the address lines is not guaranteed to work on your OS and 7.1 is not supported at all. The AccessHW dll must also be written for the OS and it will not happen. I say LabVIEW upgrade and use VISA or stick with an older operating system.

• I'm waiting times tries to access a parallel port with VISA

  I get VISA time-out errors when you try to write to the parallel port. MAX said that the port works and I should be able to communicate with him. Device Manager Windows 2000 also said that the device works. I use writing to the parallel port with VISA example I found on the site of nor. To make it even more confusing (or), it runs on one computer but not another. All software and drivers are the same on both machines. On one who gives me the error of time-out, I am able to write to the parallel port using "accesshw".

  What a coincidence. The computer that I had problems with is also a Dell Optiplex. The pins of wiring together the way that you have specified has solved my problem of timeout. The cable I got with just bad has terminals 11 and 12 low attached as indicated on the page with a link to the code sample titled "with the help of VISA to access the Parallel Port in LabVIEW" I know why the original cable worked with a bridge but not a Dell Optiplex. Thanks for the quick fix!

• HP930c driver for Compaq Presario again with no parallel port but...

  I have a HP 930C printer, which works very well with as a local printer on the Dell desktop computer. I just bought a new laptop Compaq Presario CQ57, running Windows 7 Edition Home Premium, which I have "networked" to the Dell. Everything works fine BUT I want to print on the Compaq 930c, 'through' the Dell printer.

  In other words, using the 930c as a network for the Compaq printer, never as local Compaq printer.

  PROBLEM:

  to do this, I need a 930c on the Compaq driver: the original driver is on a DVD / CD that tells me that Win 7 is not up-to-date enough to Win 7 process, download the drivers from HP tells me the driver built into Windows 7 (!), but Win 7 can not finish installing the driver because the process requires that the 930C is connected to the device of Win 7 (Compaq). But the Compaq has no parallel port (only USB) so I can't plug it! And nor would I, I want to do all my printing via my network domestic (IE "by the Dell).

  Useful thoughts or suggestions on how to solve this problem would be greatly appreciated - please!

  Best regards

  Hi dutchted,

  Try following the steps below to manually add the shared printer:

  First step: find the host name:

  Since the Dell PC, right click on computer and select Properties.
  Take note of the name of the computer.

  Second step: find the share name:

  Enter the control panel > devices and printers.

  Right-click on the 930c printer, then select printer properties.

  Enter the sharing tab, and take note of the share name.

  Third step: define the shared printer on the client computer:

  1. Enter the control panel > printers and faxes.
  2. Click Add a printer.
  3. Select this option to Add a local printer.
  4. The bottom of the screen, create a new port by selecting the local railway.
  5. Set the port as \\COMPUTERNAME\SHARENAME name using the above values.
  6. Search for deskjet 930C nder H, if you do not find the driver, Windows Update, click wait several minutes until the list will reappear and select the printer Deskjet 930c, and then click OK.
  7. Follow the steps to complete the wizard, and try to print.

• Re: Tecra M11 - 15W - Parallel Port LPT1, not found in Device Manager

  Hello

  I have Tecra M11 with PA3680E-1PRP Docking Station. BIOS Version 2.9.

  Problem is, I want to use the Parallel Port LPT 1, but in anchorage additive dosent device manager there.

  Thanks much for the tips

  Hey Buddy,

  What device is connected to the LPT1 port? Usually if you connect a device to LPT port and you turn on you will be asked for drivers. AFAIK the LPT device drivers must be installed before connect you.

  Several years ago I also used LPT connection for my printer but one day it didn't work. The problem was only a defective cable. I replaced it with a new one, and then the connection to the printer has been recognized again correctly! :)

• HP Pavilion p7-1026 b: parallel port

  I recently bought this computer used for a CNC machine by computer I am building. I need to install a parallel port so that it works correctly.

  I bought this port parallel http://www.pmdx.com/2PARPCI , and it does not seem to adapt to any location. He really did give me 2 ports.  Can you advise me on which one to buy. Or an adapter to make this one work. Looking at the pins on the motherboard of the PC it seems that the slot is back on the mother. Or the notch is on the wrong end.

  Thank you for your valuable time.

  You are the very welcome.

  Unfortunately, I have never installed one myself.  All my HP computer business came with parallel port cards.

  I take one in the list I posted and get the best market with the best / most of the critics.

  Wireless... I do not use the internal wireless cards.  Had too many problems with them.

  I use this external dual-band USB wireless network adapter on my HP 3 business desktop PC.  Works fine on W7 - W10.

  I used the W7 drivers that come with the disc for the W10.

• HASP dongle (parallel port) on the A100-906 Satellite connection

  I need to work with Solid Works software. It is protected with HASP dongle which should be connected to the parallel port (printer port). But there is no such port on my Satellite.

  What can I do?

  Several ideas of spring in mind:
  -try to get your software vendor to replace your dongle with a USB version (possibly you will get a free)
  -get a parallel converter cable / usb (not guaranteed)
  -get a parallel PCMCIA card (a bit expensive...)
