• I've updated my Ram in my Acer Aspire 5532 3 GB to 4 GB and it shows that I use only 2 GB and I have an empty slot

  I've updated my Ram in my 5532 Acer Aspire from 3 GB to 4 GB and
  When I run a check on my computer using my Norton 360 it shows
  I have 2 GB and I have an empty slot for the ram, but I have a 2 GB
  in it. What can I do about it? How should I do?

  Make sure that the RAM module is installed correctly.

  If you are running Windows 7 32 bit, you can recognize 3.2 GB of RAM.

  My PC running the 32-bit version or 64-bit Windows?

• I want to improve memory on iMac 27 in. 3.3 GHz, 5K retina. He now has two 4G of Ram. I want to add two 8 G of ram. Should I remove two 4 G, or simply add 8G in two empty slots? Going to have a mixed match (2 of 4 and 8 s 2) in trouble?

  I want to improve memory on iMac 27 in. 3.3 GHz, 5K retina. There are now two 4 G of Ram. I want to add two 8 G of ram. Should I remove two 4 G, or simply add 8G in two empty slots? There are 4 slots for RAM.  Going to have a mixed match (two 4 and two 8) in trouble? Or will it improve my speed giving me 24G of RAM?

  It will be fine as long as they are installed in pairs (and, as long as your model can handle 8 GB modules). Just install them in the empty slots. Working with word documents or online will be not much faster - you will notice the difference in speed apps to respond, with graphic design and video editing, etc or game play. The new OS versions like more RAM, so you can not go wrong there.

  FYI, you do not run iOS on an iMac - Please edit your profile to show what OS version you are using. It helps the helpers.

• Difference between the cDAQ-9174 and cDAQ-9178

  I have several cRIO-9081.  Each cRIO-9081 running NOR-DAQmx 15.5.  On four of the cRIO-9018 we show you cDAQ - 9178 with 8 modules.  Everything just worked.  On the fifth cRIO-9018, we tried to connect a cDAQ-9174.  The aircraft appeared in the Windows Device Manager and MAX, but MAX has indicated that the aircraft was missing (error-88705) and that Windows can't find a driver for the instrument.

  We then plugged a cDAQ-9178 in the fifth cRIO and everything just worked.

  What is the difference between a cDAQ-9174 and cDAQ-9178 other than the number of the module support?

  Hi Paul,.

  It seems it could be a driver problem! What DAQmx version you have installed on two computers? Reinstall the latest version may be worth it because it looks like there may be corruption. You can find the latest version here: http://www.ni.com/download/ni-daqmx-15.5/5901/en/

  You can manually associate the device driver, here: http://digital.ni.com/public.nsf/allkb/5B80CAAA64413B4C86256C5E0000C1A7

  There are modules connected to the cDAQ chassis?

  Also, sometimes, this can happen if you do not restart your computer after the installation of the NOR-DAQmx driver. Restart your computer after the driver installation will allow you to reserve the device successfully. Here are a few others not to try:

  • Check the charger to device OR to see if it is running
  
  
  • Reset the service OR charger
  
  
  • Reset the MAX Configuration database
  
  
  • The system power cycle

• problem installing driver cDAQ 9174

  Hello

  I am a new user of LabVIEW and just got our first shipement material today of 2 x cDaq 9174 with analog i/o.

  I tried to install the driver for several hours without success. At the beginning of the installation, I get an error message that says:

  "This installer needs to access 'My images' However this place XXX is not available." Make sure that this directory exists and is available, and rerun Setup.

  First of all, the folder my pictures pointed to a NAS drive where all of our photos of the company are located (which was the N drive) - so I show it to the location of the normal C drive but it is still giving me an error message and try to find the folder in drive instead of C N (and Yes I tried to reboot).

  Secondly, the location was available, as I opened through Explorer without any problem.

  Thirdly, why a driver would fail to install simply because it could not access the folder my pictures?

  Any help would be appreciated.

  Hi Doug_1970,

  It may be a registry key which is always pointing to the NAS drive. Try to use the following Microsoft Fix it tool, reboot, then install DAQmx.

• cDAQ-9174 cannot use the counters of 3 or 4

  Hello

  I try to display the entry of a potentiometer and 3 encoders of Quad.  I have a CDAQ-9174 with a 9215 OR (for the POT) in the slot 1, 9411 or in slot 2 and a NI 9401 in the Groove 3 (soon to another NOR 9411 when it happens).

  If I run the example 'Measure angular Position.vi' on each individual encoder (by selecting either modules on counter 0), I can see all three encoders work properly (exit count increments and decrements as expected)

  If I run the Test panels able and automation, I see all three encoders switch their respective 2 channels each.

  But when I change 'measurement Position.vi"to have all three separate entries (I copied the task of creating and all its entries twice, then expanded the while loop to have three different DaqMX Read vi, then 2 clearer spots on the right side (output) at all in a loop), I see only 2 encoders increment and decrement.

  I do not use Index Z entries, I changed the type of decoding to X 2 for all three.  I tried to change that, but I especially get the same result (2 encoders working, is not 1).

  I changed the encoders are the use of counters to 0, 1, and 2.  Only the assigned to counter 2 encoder does not work.

  I tried to use meter 3 - same problem.

  Is there a way to confirm that the cDAQ-9174 counters all work?  I tried all three in the test panels and they seem to be good?

  A cDAQ-9174 can manage 2 Quad encoders using 2 signals of each (A and B signals - A for metering, B for management)?

  I have something configured incorrectly?  If you use two Modules of entry at the same time, is it some additional configuration that must be done?

  Really appreciate some help here.

  Thank you

  Sam

  Yes, we use the 9.0.2 version drivers and no there is no error message.

  Turns out we had wired it incorrectly for Counter 2 use.  Being on the second module, I thought we had wire the same way the first module has been wired - not realizing that counters need a provision of the specific pins.

  Thank you for looking into this.

• My Mac has 4 slots for memory, 2 slots hold 4 GB of memory each.  In the empty slots add 8 GB in each of them?

  My Mac has 4 slots for memory, 2 slots hold 4 GB each.  Can I add a 8 GB memory in each of the empty slots?  I can add memory higher in the empty slots or what I need to keep all memory equals 4 slots 4 GB each?

  It depends on what iMac you have. Some older models may not recognize 8 GB of memory chips.

  My settings > General > regulatory screen showing empty (check screenshot below) is there someone tell me why it's like that

  

  It may be a bug or something like that. Try restarting/resetting your phone. This will not erase your data stored on that device.

  • Press and hold the sleep/wake button
  • Press and hold the Home button
  • Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.

  Alternatively, you can go to settings - general - reset - Reset all settings

  If that doesn't work, restore your device to factory settings. Please note that this will delete the data on your device.

  Take a look this Apple Support article: use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.

• Hi all, I have an iMac (21.5 inch, mid 2011) with 4 memory slots, 2 has 2 GB each, is it OK to put a 4 GB in each of the empty slots or should I buy 4 new 4 GB and replace all, Sebastian Cheers

  You can put 2 x 4 GB DIMMS in the empty slots, this will give you a total of 12 GB. iMacs are very sensitive to the RAM, it is best to buy RAM from reliable sources like Crucial (direct purchase) or OWC OWC RAM

• Generate a pulse train, NI 9402 modules in cDAQ-9174 chassis

  I have two modules NI 9402 in a cDAQ-9174 chassis.

  When I output a pulse train on a specific line of the PFI to a specific module, the pulse train is out on the right line of PFI, but on BOTH modules.

  I want that the pulse train out only one of the modules.

  for example, I select cDAQ2Mod1/ctr1 to output a pulse train on PFI3 of module one.  I hear the pulse module one PFI3 train, but I also get it on PFI3 of module 2.

  I am also a measurement of separation of two edges with a different counter, but I don't seem to have this problem.  (The measure only works when I have the signals connected to the module that I've specified.)

  -Paul

  This is the Vi I work with.

  Hmmm...  Looks like it's actually only after I exit a signal on that line.  Maybe I should try to clear the line.

• cDAQ-9174 error-89137

  I have a cDAQ-9174, I want to configure to use and DI, at the same time in two different tasks. It gives me the following-89137 error:

  Possible reasons:

  Specified route can not be satisfied, because it requires resources that are currently in use by another route.

  Source device: cDAQ1
  Terminal: / SampleClock
  Target unit: cDAQ1
  Destination terminal: Slot1/ConvertPulse

  Resources in use by
  Task name: _unnamedTask<32>
  Source device: cDAQ1
  Point source: di/SampleClock
  Target unit: cDAQ1
  Destination terminal: Slot1/ConvertPulse

  Task name: _unnamedTask<33>

  I understand that this is because some courses is in use, but I don't know what that means. I tried to reference the peripheral roads in MAX, but I don't really understand. I have attached my code. You can see that I want to read and write at the same time, which I think should be a fairly simple thing to do. I found a note on the site NOR on the definition of the clocks with the Timekeeping property node. I tried to do, but I couldn't make it work anyway.

  Can someone tell me how I can use DI and PERFORM tasks on the cDAQ even at the same time?

  I figured out that I can not do readings of equipment timed at the same time, I do timed written with this module, so that was the problem.

• synchronization and clock cDAQ-9174

  I have a cDAQ-9174 with chassis

  HAVE - 9205 OR 9205

  HAVE - NOR 9219

  DIO - OR 9401.

  "NOR-DAQmx allows the on-board clock routing synchronize acquisition or generation of data transactions. A single sync signal or a trigger can be shared between multiple operations on the same device to ensure that the data are synchronized. These signals is shared by the simple signals routing functions that allow connections integrated hardware DAQ. " (from http://zone.ni.com/devzone/cda/tut/p/id/6829)

  When I check the itineraries device in MAX tab' for chassis and c modules individually, I found many clocks with the Green blocks (direct Route). "Once a physical connection is determined, the NOR-DAQmx driver lets the user quickly and easily use this connection to synchronize operations".

  Now my question is how do you choose among these clocks available. What is the frequency of these clocks? The highest frequency the better? What is the difference between /Ctr0SampleClock, /Ctr0InternalOutput, /Ctr0Source, /Ctr0A?

  For example, why well/Dev1/I/SampleClock or Ctr0InternalOutput or of others, especially as a source for the .vi DAQmx Timing (sample clock)?

  Thanks a lot for your help

  Concerning

  Hello NCLbingji,

  I think you mix instructions from the manuals of different material. The link you posted refers to the synchronization of several separate devices, while your cDAQ with its modules really is like having one device almost. You will find more relevant information in your manual of cDAQ chassis. For multiple devices, you indeed have a "physical connection", but with the cDAQ is not necessary. You set up these connections in the software in any way, and this should get the routing sorting at the driver level.

  Try to identify which channel will be your a 'primary', the one driving all others and synchronization, the value then asked SampleClock of this string as the rest (DAQmx Trigger.vi) trigger ('secondary') channels, then start all 'secondary' jobs and finally start your "primary" task This will trigger all tasks at the same time. Take a look at the attached picture, which is another application that I worked on, but I think this will help.

  I hope this helps.

  Kind regards

• DASYLab w / support NOR-DAQmx NI 9227, NI 9229 &amp; cDAQ 9174

  I am trying to use DASYLab 11 w / NOR-DAQmx 8.5 to my configuration material of NI 9227, NOR 9229 & cDAQ-9174. After decommissioning of my PC Win7 for XP that takes in charge OR-DAQmx 8.5 (the OR-DAQmx last, supported by 11 DASYLab), I discovered that NEITHER-DAQmx 8.5 does not support the cDAQ 9174. Right now, looks like I'm watered except so use LABView. Is there any other way at this time to use this hardware configuration with DASYLab or any other application?

  DASYLab V11 supports Windows 7 when you install the Service Pack (see www.dasylab.com).

  Where are we going to say that it does support NOR-DAQmx 8.5? I installed the most recent NI.com last week, and it seems to work very well. I use only simulated devices so far, but DASYLab is data collection and display correctly.

• cDAQ-9174 with modules 9225 and 9239 for issue of power measurements...

  Hello to one and all.

  I do turn a cDAQ-9174 with modules 9225 and 9239 to measure the voltage (120, 208-240, 277 VAC) and current (via the clamp amp i400, Fluke - 10mA/exit A) respectively.

  I have the set scale scale Differential No. (1:1 I guess) for 100: 1 for current and voltage.  With the acquisition mode set to "N samples", 10 samples to read, at the rate of 500 m.  This feeds into 'EPM_Power.vi' (polymorphic VI of the palette of EMP... can be downloaded here, http://sine.ni.com/nips/cds/view/p/lang/en/nid/209826)

  I try to check my numbers with an Analyzer of power quality of 435 Fluke and supporting that upward is a Fluke 179 True RMS DMM with clamp amp i200 (for current playback)

  Now, I'm running is my numbers I take data look like they're following a curve of fishing... the averages are on the right, but when my blood pressure is expected to be relatively stable, it's over the map... same story with my current readings.  I tried several different filters without success.  I would like to have relatively stable values for voltage and current so my other values are correct.  Is there a signal conditioner or filter that will help with this?

  As always, a point in the right direction would be greatly appreciated!

  Thank you!

  Chad

  Hi, Will,

  Your request for a screenshot actuall lead me to the solution.  Not enough samples!  I took little data too slowly and only seeing part of the wave of fishing AC each iteration.  .. that became glaring when I tried to this graph.  So I increased my sampling of 100 to 5 Hz and things seem to have settled things down a bit.  Thank you for the good question!
