• 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.

• Using the Parallel Port

  Windows does not allow for QBASIC uses the parallel port (address = 888 or 378 h)

  If you know the 3rd party software that there access to this port it please tell me

  and why user port does not work with windows vista

  Most any version of Windows that is based on the new testament 'sources' (Windows NT, 2000, XP, Windows 7, Server 2003/2008) all do not support 'direct' access parallel ports / series. This is normal.  You may need to add a non-Microsoft Windows 'core' driver to allow this access.

• 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.

• Driver files that run the parallel port and USB port

  In the system information utility where to look to find the parallel port and the port driver USB, name of file that manages these?

  Know the drivers specific, is only half the story.  Why you looking for these drivers?  You have problems with your parallel port or USB port?  This can be caused by problems with drivers or it could be a hardware problem (hard to diagnose a hardware problem without good parts to swap and test).  If you need to update the drivers, you must use device (not msinfo32) Manager - or maybe clicking on an executable file that loads the drivers automatically (depends on how it is sent by download).

  Go to the Device Manager by going to start / find and type Device Manager and enter and then double-click on the program icon that appears.  Check each device to a red x, yellow! or white?  These identify devices with problems probably (drivers, but also of conflict or something else).  Click on each for more details and troubleshooting tips.  If you need drivers (I assume that you want to the parallel port and USB ports), get the computer dealer or the manufacturer of the device (NOT of Microsoft Updates).  In fact, you must disable automatic updates in Windows Update driver as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Follow these steps to get the drivers: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm.  Once you have the drivers, you can install them via the Manager device as follows: http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html.  Or run the Setup program of driver provided by the vendor of the computer or the manufacturer of the device.  Be VERY careful get Vista compatible drivers for these devices are difficult to identify (they usually come with the numbers of model or something like that if they can have serial numbers) and using the wrong drivers could make the problem (whatever that is) worse.

  If you update the drivers succerssfully and the problem persists, then it is probably a hardware problem.  In this case, contact the manufacturer of your computer for technical support (hopeully it is still under warranty) or bring it to a professional computer repairman (NOT Geek Squad or one of those big store centers because they don't really know what they're doing and charge a lot for this level of expertise) to have the components tested and possibly replaced.

  I hlpe that aid.

• Use of the Trunk Ports (Cisco) on the management interface

  Hi all

  Background:

  We are in the process of consolidation of 2 farms of esx servers and will end up with 10 guests in a single cluster. Guests come from 2 VLAN separate (say 10 of VLANs and vlan 20). A test I took one of the hosts of HA/DRS and tests with it. For HA and DRS to work efficiently and properly in common all resources, we all want vm to leave both VLAN access to move to any host in the cluster.

  The test:

  My single host mentioned above, I created 2 groups of ports on a vswitch, vlan10 tag and with vlan20, I deployed a VM and tried on the two IP address ranges. It worked (with the correct settings of defined IP by VLAN) but as soon as we resources shared the port used by the management of network vmkernel port we lost the connection to the HOST from a management perspective. What the question is that it is possible to connect the management network a trunk port? We have 2 network interfaces connected to the vSwitch and both used for the VM traffic as well as management traffic. That's how they are currently implemented except that the switch port is on a VLAN-specific rather than shared resources.

  Thank you very much

  Chris

  Hi Chris

  Yes, the network management also accepts the vlan tagging/trunking.

  Just add the number VLAN on the Portgroup.

  Maybe you can do a printscreen with the current configuration?

• Problem for my compact DAQ recognize the parallel port

  Hello

  I have a NI9133 compact DAQ, which I would like to connect the modules OR.

  My problem is that it is not recognized OR max. I guess I'm missing some drivers; I have reinstalled twice DAQmx 15.0 completely, but I still have the same question.
  Turning to the images attached, it seems that the parallel is not recognized.

  I tried many different things to fix it but to no avail. If anyone can help me

• 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

  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.

  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.

• How to get the driver to a parallel printer using windows update without a parallel port on my laptop?

  I have an asus WL500g and I use it as a print server. On my big pc on windows 7. I managed to install the driver on the printer directly on the pc connection an update of windows to get the driver of the Sina. After installing the driver I passed it to the port by using the ip address of my router. It works, but my laptop doesn't have a parallel port, so it is not possible to obtain the driver. What can I do?

  You do not want drivers for parallel port on the laptop anyway given that the laptop is not connect via the parallel port, but rather on the network. You would most likely want to install drivers on the laptop Asus print server, and then print to a network printer drivers. Download the Asus former and latter printer mftr.

• 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!

• 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.

• Using the Serial Port for data acquisition Non-Serial

  I searched the forums and can't find anything on this topic.

  I saw that it was possible to use the parallel port for e/s digital single and I was hoping that the serial port can be configured the same. It seems all VI VISA only to use the serial port to receive ASCII characters at a given flow rate, but is it possible to simply query the status of the line series at my own speed to see if it is high or low, kind of like a single pin DAQ?

  It seems that it would be possible until the serial data are read and controlled by labview, not Windows. Let me know if you have ideas of how to approach this problem, or any comment as to why it is not possible.

  Thank you all!

  Select the property > settings series > Modem of the line parameters. For example, the State of the CTS is an entry to the pc.

  With the help of these lines is a very poor substitute for a scope or map DAQ. The only things you can return is Asserted, Unknown or Unasserted. The range of acceptable signals is important enough. Anything between + 3 and -3 is an unknown state. Your other signals is + / 3 to 15 volts. What type of signals do you really want to capture?

  Edit: there is no such thing as a visa so I have no idea of what you actually use.
