• How to program a remote adjustent with a Laser sensor and a pressure valve

  Hallo,

  I'm looking for a solution set a monostable pneumatic cylinder via a laser sensor and a pressure valve.

  The Laser sensor and the valve has a domain controller as a signal input/output. The position of the cylinder is controlled by the laser sensor and pressure valve schould adjust pressure as needed to get the cylinder into position.

  Sample:

  The cylinder schould be 5mm extended from the initial position. If a team is on the stem of the actuator pressure valve schould be able to increase the pressure in the cylinder so that the location of Rod 5mm remains approximately constant.

  Thank you for a few suggenstions!

  Kind regards

  I guess you could use a system by which the laser sensor output when it receives the laser beam.

  Something like this:

  Laser has detected ==> move in the first direction

  Laser (later) has detected ==> move in the other direction

  Laser (later) has detected ==> move in the first direction

  ..........

  So that it switches between two States.

  Or if it is possible, you could just output intensities different laser to represent different values.

  You could get the signal valve dc, translate to a numeric value, set a threshold (or an upper and lower threshold could be better) where the system is stable and doing some codes to ensure that the valve maintains the pressure inside the threshold.

  The rest I think is too deep, and I guess it's to you from there

  See you soon

• Why the button "Save as" does not work in new Acrobat Reader? Very annoying...

  Why the button "Save as" does not work in new Acrobat Reader? Very annoying...

  I have already updated to the last DC v15.009.20077...

  So I found a way, if I do it just right, it works (with the file, click the "tiny" file and then save as. I made the mistake of first pressing the home much more first. Really not intuitive or easy to use even if... Looks like you have replaced the button "save under" with the "save in the cloud." We use mettle at work, and the cloud of Adobe is irrelevant for me...

  Se, Reader cannot do this. You can do it with a subscription to services pack pdf or the full version of Adobe Acrobat.

• When I plugged in a new card reader, I lost all my saved for importing metadata presets. Now, when I type in a new and save it, it is not available. Help, please. Thank you, dwc

  Hi people,

  When I plugged a new card reader, Lexar Pro USB 3.0 Dual Slot player, I lost all my saved metadata that are used for imports.  Now, when I type in the metadata, it registers on the photos, but then it is not saved for later use, as it was before. I'm trying to save him, but it does not work. Any ideas? Is Lightroom 3, version 3.6.  10.8.5 Mac.  Thank you, dwc

  I think that's the problem. Go to the original catalog, uncheck it, close LR, open LR, and create the new catalog.

• Reading from the sensor to LabView via rs232 or Subvi problem

  I'm quite new to LabView and not too experienced with instrument control so I was wondering if someone could help me to solve my problem?

  Currently, I'm using LabView 2011 and I'm trying to read pressure DualGauge of Pfeiffer (TPG 262) pressure sensor and display the readings of two pressure on LabView.  However, when I run my program, the pressure readings are not displayed - what is displayed are default 0.00 if same mBar pressure reading a reading of the display of the DualGauge probe.  To connect the sensor, I use a RS232 cable and have managed to find the device on my device manager, so I don't think that the connection is the problem (I've also seen the port appears in the Device Manager, when I connected the sensor via RS232 and USB in my computer).  I also use Subvi Pfeiffer in my code, and I suspect that the problem may be in there.

  Attached is my code and here are links to the manual of the DualGauge and the driver of the software LabView of Pfeiffer

  Double manual gauge - p. 23 and 68 are probably the only things related to the RS232 connection.

  Any help is very appreciated!

  You have not tested really do anything. Devices and MAX Manager displays only the com port that you added to the computer. It does nothing to verify that an instrument is truly connected. You might have the wrong settings of com or the wrong type of cable serial (null-modem is required). I suggest that you start with program such as hyperterminal, PuTTY or MAX and try something simple. It seems that you will receive an acknowledgement returned by the instrument when a correct command is received. Make sure that this simple step that happens.

• Send the command to laser sensor via a serial port RS232

  Hello

  I have a sensor of moving Laser of OPTEX FA Co., LTD. with a Communication Manual.pdf file attached. I modified the sample base series write and Read.vi of LV to send the command to the probe in order to receive a response. However, LV always returns an error on my VISA Write.

  In short, the structure of command for the sensor must have a form like this

  STX-command command-space-1 2 - ETX

  (more can be see the manual on page 3 or 18 of the .pdf file)

  where

  -STX: code showing the head of transmit data (02 H)

  -Command 1, 2: could be refers to table 1, 2 and 3 of the manual.

  -ETX: code illustrating the completion of data transmission (03H)

  For example, if I want to ask the sensor to send the data from A sensor head, the command must be

  STX-ABLE () A - ETX

  (20H) space is shown as ().

  I tried to send a string HEX (02 - 4 d 454153555245-20-41-03) for this command to the entry VISA, but all I get is ERROR.

  I enclose with this thread my vi and a printscreen of the ERROR.

  A lot a lot of appreciation for any help from any of you.

  I have my LV code can run successfully. He can read the COMMAND and return measurement data. The last time does not playback VISA because I used a cable RS232 to opportunity, and someone operated two pins (2 and 3) for another application.

  Heya,

  When I read your post, I initially thought you were posting a tutorial on the question of whether or not a chosen user name is already resigtered on registration as this tutorial page:

  http://DwFAQ.info/signup_demo.php

  User name of Spry availability

  Then after looking at the page you linked to and try to understand the purpose of this tutorial, I've noticed that you're talking about something like this:

  It's pretty simple to do with the link I referenced. Just create your database with populated tables, use the script mentioned to convert data from the database in xml syntax, then enter your dynamic database script as the location of the xmlDataSet linked spry page.

  View source on this page which shows the non-destructive filter in action to see how it's done! You can also Spice it up a little products, etc. using this method. The key is to create a dynamic xml from your database syntax, and then use the location of the dynamic xml as your xmlDataSet script in the search page.

  I have an example of the auto suggest search on my homepage http://DwFAQ.info

  On the upper-left corner of the page, click on the link that says search for tutorials to bring up the search form. Then start typing characters in the search box to view the Scriptures instantly filter depending on the characters that are typed. You can also further filter by clicking on the category checkboxes to filter by keyword AND category.

  You can view the source code on my site to see the location of the dynamic xml syntax that is referenced as the location of xmlDataSet and how it has been implemented in the site.

• How can I get firefox to open a pdf file in adobe instead of the new pdf reader?

  Before the recent update, 19.0, I google something and see [PDF] next to a link. I click the Center button to open it in a new tab. Firefox might download the file and open it with Adobe Reader. I like this.

  With the new update 19.0, the pdf file would open in the new tab. I have to down load it and then open it in Adobe. I don't like this.

  I'm going to preferences under applications. I look to see if I can change that. Next to document Adobe Reader, I choose to use Adobe Reader, but when I click on a link [PDF], it always opens the file in Firefox and not Adobe.

  I want to go back to the way it was.

  Problem: Open a pdf file in Firefox, he wants to save the file.
  Remedy:
  In Firefox, tools, Options, choose the column on the left (Content Type) Applications tab, select Portable Document Format (pdf). Right column (Action) choose Preview in Firefox.
  I use Firefox 21.0.

• New ink cartridges with no sensor

  We bought replacement cartridges HP for HP 6500 has more printer (920XL cartridges) and they do not work with the printer. It seems that they do not have the same sensors as the old cartridges (see the top of the cartridge vs. the bottom page).  We bought a set of WB Mason and tried a second series of Staples, but we had the same problem with both sets.

  Someone had this problem recently?

  

  Differencess you notice are due to a HP change made in the body of the cartridge as shown in the document here.  The two cartrdiges the old and the new should be accepted into the printer.  What is the error message you see on the printer?

  If the printer is giving a message "the following ink cartridge is missing or corrupt...". ' the document here can help.

• 6710 Pavilion: A newer card reader will replace the 504857-001 in my Pavilion

  I need to replace my Pavilion card reader.  A new HP card reader will replace my PIN 504857-001, or should I find a 857-001?

  HPElliteate, welcome to the forum.

  I would appreciate it if you would complete the computer model number.  There are 36 versions of the 6700.

  If it were me, I would buy an external USB card reader.  They are much easier to install and you can use it with all your computers.  I have an internal drive and external.

• How do I switch between document windows in the new Acrobat Reader ms?  (Mac desktop running Yosemite.)

  Y at - it a keyboard shortcut to switch between documents on the new domain controller Acrobat Reader?  I think that it used to function-Tab.  This no longer works.

  Thank you, abhissha, but that alternate between different applications on the desktop open.

  I found the correct answer, however, which I believe is the same as it used to be (how I missed originally, I don't know):

  Control + Tab to move between open documents in Acrobat.

  Thank you.
