Synchronisation with a slower external signal

Hello,
I would synchronize 1 KHz continuous acquisition with an slower external clock. For example, I have a 100 or 200 Hz external clock and on each clock signal, I would read the acquisition buffer.
On which pin of the DAQ board could I connect the external code ?
Which function could I use on LabVIEW to synchronise the application with the external clock ?
Thanks for your input
Hubert Robitaille

Hello;
I don't know if I got your application need correctly by your description. By my understanding you want to have multiple external signals clocking each channel of the DAQ board.
If that is the case, it's not possible, since the DAQ board accepts only one Scan clock pulse train. One thing you can do is to use the fastest clock as the external scan clock, and then skip some points on the other channels so you can collect the datapoints that match each scan clock needed.
Hope this helps.

Synchronise digital pattern output(6533) with a external signal

I use a PCI-DIO32HS and i want to synchronise an output pattern with an external signal(TTL;T=1.7ms).
ie :every time external signal become high(every 1.7ms)
my dio32HS output a define pattern on a line.
How can i do this?Thanks

Thanks for your answer but see attached file to see what i want to do.
I want to control delay between trigger(input signal T=1.7ms) and ouput and control the width of the ouput pulse

How can I get Aperture to re- synchronise with an external folder

Does anyone know how to get Aperture to re- synchronise with an external folder?
I reference my images on an external hard-drive.
I often will move images or add them via other programs. I would like to then re-sync and have Aperture add the new images to its library.
Lightroom does this very well but no joy in Aperture.
Joe Barrett

OK I know understand your question
I do this as part of my workflow - I put all images into folders on the hard drive and then import them into Aperture as Referenced Masters
I select the Library Inspector and select the higher levelProject I want to store the images in (or create a New one)
Then I go to the
File
Import
Folders as Projects
Then select the folder tree that you wish to import - BUT ENSURE that you select where you want to store the files.
I keep them in the current location as I prefer to have referenced files
also adjust the other import controls as required.
Then run the import - it may take a while to create the library records ad Thumbnails.
Use the Aperture Preferences window to switch off Faces.
Hope this solves your problem

Generating signal from the 5412 which is in sync with the external signal

Hi,
I am using the 5412 AWG. An external signal comes from the test unit. I need to generate a signal to the test unit which should be in synchronous with external signal which comes from the test unit. Can anyone help in this?
Regards,
Rajashekar

Hi Rajashekar,
You could synchronize these two signals by sharing a start trigger and using the input signal from your test unit as the sample clock for the 5412. There are some considerations when doing this that can be seen in the External Sample Clock Considerations section of the 5412 help linked below:
External Sample Clock Sources
If you are using LabVIEW, you can find examples in the Example Finder located at Help >> Find Examples. The FGEN examples are located at Hardware Input and Output >> Modular Instruments >> NI-FGEN >> Arbitrary Waveform Generation. You can choose which line to use as the sample clock. You will also need to add in some triggering. You can find an example of triggering at Hardware Input and Output >> Modular Instruments >> NI-FGEN >> Synchronization >>FGEN DAQmx Synchronization.vi. This is synchronizing to a DAQ card, but you can synchronize to your external signal just the same way, i.e., sharing a start trigger and a reference clock.

External user list synchronisation with Login Server

Hello:
I am using a Portal external applications to allow users to access the application from Portal without having to login again.
If the username or password of the extenal application should change, how can this be synchronised with login server?
null

There is no automatic way that passwords are synced between the login server and the external application. The user is responsible for updating the login server's stored password for the external app when the user updates it in the external app.
This is done by clicking Customize on the External Applications portlet and clicking the "Edit" icon beside the application of interest.

Can I trigger the read of a buffer period measurement with a external signal (PFI line) with my 6602 card? How can I do it?

I am doing a buffered period measurement with a 6602 card, Labview real time. I want to measure the period of 6 rising edges of a TTL, but I want to do it exactly when an edge comes on other external signal (of course slowler than the previous one), that is to say that I want an external start trigger. Can anybody help me? I have hardly searched at the web and I have not found an example of code of what I am looking for.
Another question:
After reading the buffer, how does my program know that the data has been refreshed in a continuous measurement? I attach two VIs I am trying to make work and a quite explanatory bmp of what I
want to do.
Thanks.

Hello;
I can't think of any way to accomplish that task. Once the counters have only two input pins, and both are in use when one configures the counter to do buffered measurements, there isn't a way to trigger that operation in hardware.
I'm not sure if I understood your second question, however, the buffered operation on a counter is hardware controlled, meaning that a pulse on its gate input triggers the transfer of the count value from the counter register to the PC memory buffer. That is therefore a continuous measurement.

Slow performance with high resolution external monitor

Hello,
I recently bought HP EliteBook 840 G1, i7-4600U, 8gb ram, HD intel graphics 4400, 256GB SSD.
Everything would be fine, but when I connect my 30" Dell monitor with 2560x1600 resolution as an external monitor, the performance of the computer drops significantly to the point where it becomes unconvenient to work with programs that require more resorces.
I understand that it might be due to limitations of the hardware (most probably graphic card is too weak ? ), but still I'd like to ask if there is anything I could do to boost the performance of HP Elitebook with high resolution external monitor.

Hi, you should use renderMode = gpu in your application descriptor xml file, especially for latest android devices. But gpu is not a good idea for old devices, so you may also try renderMode = direct.
Honestly, I don't think those android devices made in china have good performance, especially gpu.

How do I create an interrupt on the PCI-DIO-96 from an external signal connected to the lines PC0 or PC3 of a port?

Hi everybody,
we are currently using the PCI-DIO-96 for data acquisition from an old AT-DIO-32F card. All PPIs and ports work in mode 0 (standard input/output). The manual mentions the possibility to create an interrupt from an external signal connected to the lines PC0 and PC3 of port C from a PPI. To get the interrupt I have connected my interrupt service routine to the PCI-DIO-96, enabled the master interrupt enable bit in the interrupt configuration register 2 and enabled interrupt enable bits of every PPI chip in the interrupt configuration register 1. The interrupt should be generated if a signal low-to-high transition occurs on th
e lines PC0 or PC3 of a PPI. We've simulated the signal low-to-high transition with an external voltage source connected to the line PC0. We actually saw in the memory that the line toggled from state low to state high, but no interrupt was generated. I don't have a guess what I am doing wrong. Perhaps anybody knows the solution of this problems.
Thanks and best regards.
Sven Jungnickel

You may want to try disabling your USB or IEEE-1394 host controller. It's possible that one of these devices could be on the same interrupt as you DIO-96 and causing the interrupt to not be serviced.

Can i connect an external signal generator to the NI7344 to...

Can i connect an external signal generator to the NI7344 to use its
PID characteristics to precisely control the output
I am using the flex motion board (NI7344) to control the force output
of a linear motor. Using contouring and buffer operations i have
successfully created a system which can output a controlled force
which sinusoidal in form. I can achieve a reasonable output for
waveforms of 10Hz, the use of higher frequencies is limited by the
contouring operation ( a frequency of 10 Hz means i can only describe
one period of a sine wave with 10 points ( 10ms between each point =
10Hz). Can i therfore connect an external anologue wave generator to
the NI7344 use and use its PID characteristics to output wave
forms of
higher frequency ??? .....could i output an anolgue wave form from an
E-series DAQ via the RTSI cable to the NI7344 and control this ???.any
ideas or advice would be much appreciated.

Duncan,
You can use a DAQ card to output an analog waveform, but it will be a software call not part of an onboard program. RTSI can be used to pass clocks and trigger signals, so if you want to route a clock signal to do the control you could.

How to reset a counter on external signal in LabView?

Hallo there!
I am using LabView v 8.5 and the NI USB-6211 to acquire signals, among them are the following:
1) angular pulses from a rotary encoder
2) a reference pulse for the rotary encoder witch will give a pulse on a specific position of the movement for every rotation
3) value from a pressure sensor
What I am trying to do is to create a pressure/volume diagram based on the pressure and volume inside a cylinder of an IC engine. To do this, I will need the angle of the engines crankshaft to calculate the pistons position in the cylinder. This way I can calculate the volume and put it in a xy graph to represent the volume (x-axis) and the pressure(y-axis).
I am using clk0 to count the pulses from the angular encoder, and this works great. However I now need the reference pulse to somehow reset the count at the precise time it goes high in order to precisely know the angular position.
How can I do this? And how precise will this be? And will I need any kind of synchronization with my pressure measurements? If so, how?
The relevant part of the program I am working on resembles the Count Digital Events with reset.vi 33 KB as found in this thread. However, I don't know how to get the reference pulse to reset as the stop button is. How can I do this?
In addition: the fast pulses of the angular encoder = 0-> ~10kHz. I seem to lose information if I use the basic level trigger detection.vi when I put this signal on an analog port.

Hi Nick,
If you have an X Series or 2nd Generation cDAQ chassis (basically any cDAQ chassis except for the 9172 or 916x sleeves) then you can implement:
1,2,3,4,5,6,7,8,9,10,(reset),1,2,3,4,5,6,7,8,9,10,(reset),1,2...
You would have to configure an Edge Count Task, set the initial value to 232 - 6 (such that the 6th count causes the counter to rollover, which generates a pulse on the counter output), and enable the count reset using your external signal:
The count reset isn't currently available for other DAQ devices, but I believe it should be available on M Series (62xx) and TIO (660x, 6624) with a future driver release (some time in 2012).
If you don't have an X Series (or gen II cDAQ), don't despair. On other hardware, you can get close to the previous behavior with a counter output task, with the exception that the "reset" signal would only be detected after the 2nd tick after your pulse is output. Also, the reset signal would have to occur at the beginning to arm the counter the first time.
Or, you can get the 3rd behavior that you asked for by doing a continuous counter output task with the external signal as the source of the timebase ticks. For example:
1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9
In toggle mode (default):
6 ticks of initial delay, 2 ticks high, 7 ticks low, 2 ticks high, 7 ticks low, ... etc.
In pulse mode:
6 ticks of initial delay, 9 ticks high, 9 ticks low, 9 ticks high, 9 ticks low, ... etc.
See here for an overview of the difference of the two modes. Basically, pulse mode will emit a short pulse when TC is reached, and toggle mode will toggle the state of the counter. You can't have less than 2 ticks as a high time, low time, or initial delay.

John Passiak

Mail constantly is synchronising with server and updating cache directory!

Mail constantly is synchronising with server (sent messages) and updating cache directory making everything slow.
I have a .mac account. I understand the concept of IMAP and that it information is stored on the server therefore it needs to update but surely not constantly and besides the blue bar sticks halfway through without completing. Please help.

I have had the same issue. Rebuilding fixes it temporarily, but it comes back....Also have an issue where Mail will not download attachments automatically. They show up in grey until they are clicked...have Mail set to download all messages and their attachments, but it doesn't want to. Very frustrating. I have begun the switch to Entourage, which is unfortunate, as I like Mail more.

E2500 has a slow, oscillating signal

I upgraded my WRT54N to an E2500 in November 2011 and I am now having problems with a slow signal that oscillates according to Speedtest.net. Results with the router are a ping of 300-500 ms and a wide variability on download speeds in a single test of 0.5 Mbps to 3 Mbps. When I bypass the router my results improve to a ping of about 65 ms and a constant download speed of about 4.25 Mbps which is the extent of what my ISP can offer due to my rural location. My network has two desktops (one Mac, one PC), an occasional MacBook Air, an occasional PS3 connection (though the variable signal has rendered the PS3 useless for online play), and my iPhone when I'm home.
So far, I have reset the router and ensured the latest firmware is installed. I also relocated the router to another section of the house, thinking it may be experiencing interference. Interestingly enough, I can unplug the router for 10 seconds, reboot it and it works great for about 30 seconds or long enough to run Speedtest a couple of times. Then it returns to the same slow, oscillating pattern.
I'm on the verge of trashing this thing and buying an Airport but I wanted to see if anyone here could offer some ideas that I haven't tried.

If you are getting the slow speed then try the following combinations of settings:
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
          1] Open the software and go to the option which says "Router Settings"
          2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
         3] Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page). Here is the link for determining and setting up the correct MTU size: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=fbf8e8564632422eaa8ea80bf9dcba64_386.xml&pid=80&re...
         4] Then go to the Wireless tab, keep network mode as mixed,
For Channel Settings of 2.4 GHz you can make Channel Width to 20 MHz only and Channel to 6, 9, 11..
For Channel Settings of 5 GHz you can make Channel Width to 20 MHz only and Channel to 40 or 161...
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
Then check the connectivity status…

E2000 SLOW AND SIGNAL VARIES

I have a couple of Vista laptops that used to access our home network via Linksys Wireless-G Access Point and that in turn was connected to a Linksys BEFSR41 v2 EtherFast Cable/DSL 4 port Router which in itself was connected to our cable modem from TIme Warner (RoadRunner service).
The cable modem is new and was working fine with the WAP setup.
To "simplify" things I recently bought a Cisco Linksys E2000 Advanced Wireless-N Router which i connected directly to our cable modem.
Our web browsing is now slow, the signal strength comes and goes (from 2 bars to 5 bars, although RARELY 5 bars). We are at most 80 feet from the router. there is literally no interference beyond the drywall separating our laptops form the basement (the WAP and Router were also originally in the basement).
I have already done all the things I have read about in this forum (re-installed, changed channels, no parental controls, updated firmware, no guest option, etc).
Unless someone has a new idea I am thinking of throwing this thing out and getting something else but I am giving it one more chance through this forum.
Thanks for any advice you can provide!

Try to change some of the advanced wireless settings on the router like Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304 and Click on Save Settings.

How do I use my late 2011 iMac ( with thunderbolt) as external monitor for laptop/Xbox or other device with hdmi as output.

May be this question has been asked thousand times. how do I use my mid 2011 iMac ( with thunderbolt) as external monitor for laptop/Xbox or other device with hdmi as output. if apple hasn't removed that feature and has just moved that functinoality to thunderbolt then how can I use it. currently there is no laptop available with thunderbolt output. no 3rd party converter available. whats the use of having feature on latest functionality if we cant use it. I wish they would have made one port has mini-dvi and other thunderbolt for backward compatibility untill some vendor comes up with converter.

It Says :
Mac (21.5-inch, Mid 2011) and iMac (27-inch, Mid 2011) and later computers support Target Display Mode via Thunderbolt to Thunderbolt cable (2 m) when the source is another Thunderbolt-equipped computer.
Name one computer model/vendor which has thunderbolt as output for display + audio. this is so stupid to move to new technology without availbility of its compatible devices.

I am having a problem with very slow start up after expanding RAM on my 2009 Mac Pro.

I am having a problem with very slow start up after expanding RAM on my 2009 Mac Pro (8 Core 2.93GHz). When I run the Mac Pro with 2 x 2Gb RAM it takes 4 seconds before the gray screen, chime and spinning wheel appear.However when I expand the RAM to 20GB the grey screen and chimes appear after a long 20+ second black screen.
The RAM modules are paored 2 x 4GB Crucial CT51272BA1339.M18FMR and 6 x 2GB SAMSUNG M391B5673FH0-CH9, all DDR3 ECC.
Reading articles on the internet, I thought it may be damaged RAM modules, but I have completed memtest and all are okay. I have tried changing the pairs around and if I use any paired 2 modules the Mac Pro starts normally, only when I try running more than 2 modules the delayed start up happens. (black screen 20 Seconds)
I also have tried PRAM and SMU resets after changing the RAM setups, and the issues always occurs when I have more than 2 modules. As you can see I have 6 SAMSUNG modules and even with identical modules the issue happens, when increasing the RAM to more than 2 modules.
The Mac Pro runs fine after the start up screen and can see all the modules, but has anyone else come across this issue, or have any ideas as to why my Mac Pro is taking 20 seconds to start up with 20 GB RAM?

Hi there. Thanks for your comments.
I have tried all the different combinations of RAM setup, and as stated in my initial topic, the Mac Pro boot up time only slows when I have more that 2 modules. Where I place these does not seem to make a difference.
I have taken the Mac Pro to an Apple Reseller technician yesterday and they where not able to find any RAM errors. Apparently the boot up time is within Apple's acceptable parameters for this set up.
Could anyone that is running a Mac Pro 2009 with more that 4 modules of RAM, please let me know if the boot up time is normal. ( the time it takes from pressing the power button to seeing the gray screen around 16 - 20 seconds)
Or is anyone else having the same issues?
thanks for your responce
