• NEITHER 9237 and SignalExpress

  I have a cDAQ-9174 with modules OR 9237 with SignalExpress 2011 for strain gage measurement. After a few problems and doing some research on this forum, I discovered that the minimum sampling frequency for the NI 9237 is 1613 samples/second. However, I need a sample of about 1-5 samples/second rate as my tests will be the order of 4 to 5 hours and record 1613 samples every second will make my too big data file. On the forum, I found these workaround solutions:

  Subset and resampling (http://zone.ni.com/reference/en-XX/help/371268M-01/expresswb/subset_and_resample/) seems to be the most recommended, however I have a few questions about this. I selected a range of subset of 0s to 1s and then choose a resampling of 200 Ms. that seems to be the more manageable sampling frequency, but then I have a problem with the export of the data collected. I get a message that says I can't export to Excel, as the data are 'not continuous' and can only convert to text. However, the text file is not really useful as it breaks down the data in individual games and puts the time in terms of dt. For small sets of data, it seems that it would be possible to manually determine every moment given by point, but I will receive a large number of data sets. I have tried uncheck the "optimize to run once" but still not the same type of data file. What makes a kind of aggrivating, it's in SignalExpress data view tab can display a graph of deformation over time, that I need in Excel.

  Another recommendation is to use the 'Statistics' using the collected samples, then changing the number of samples to change the rate. However, I prefer not to use this method because it seems to imply "at x time, average of the latter strain is y" rather than 'x time, strain is there' and I want just the value of the strain at every 0.5 s, 1 s, 1.5 s and so on (although I guess that how that differ from the subset and resample method?).

  The last recommendation I found suggested to use an N-sample acquisition, set to read two samples and then set a delay of acquisition of post about 1000 m that would have been a nice solution, but it seems that SignalExpress impossible to compile all the samples to read a log file, that I have seen only two data points when I opened it in Excel.

  I'd appreciate any help, thank you.

  Hello MAF101,.

  I ran your own project and it worked for me. I just used the following values:

  

  It worked very well, I managed to turn on logging. Then, I tried logging information in a txt file using the instructions below:

  

  I got the attached file below using a relative timestamp. It connected two samples per second.

• Connection keyboard and mouse USB Wired stall

  Hello

  My computer repeatedly interrupts the connection to my Wired USB mouse and keyboard.  Usually around one every 30 seconds, the connection falls for 1 to 1.5 seconds, then comes back.  Meanwhile, the cursor hangs - I can't click anything, and I can't press any keys on the keyboard.  For example - when I type, I have my keyboard will stop working for a while, and no text will appear.  This is particularly problematic when I play games.

  I tried to reboot the computer, reset the SMC and the mouse and keyboard.  I also tried all USB entries on my mac (4 in total), and the problem persisted with each of them.  This leads me to believe that it is either a problem with all the USB inputs, or a software problem.

  I have an iMac 27 inches, mid-2011 with OS X El Capitan 10.11.6 (specifications: 3.4 GHz Intel Core i7 processor, 16 GB with 1333 MHz DDR3 memory and storage capacity of 2 TB).

  I use a wired USB (Logitech G402) mouse and keyboard USB Wired (Razer BlackWidow Stealth).  I have the latest version of Logitech Gaming Software and Razer Synapse installed for support.

  I would appreciate help.

  Check if there are updates available driver.

  To check if the problem is with the USB to your Mac controller, test with a different keyboard or mouse.

  To check the extensions conflicts, etc., try the startup mode.

• Download speed slow r7000 (wired and wireless)

  I have the R7000 for about a year now and originally, I had the good download and upload speeds that corresponds with my ISP rates.

  Right now my ISP (cable) delivers 120 Mbps down and 12 Mbps to the top.

  However, I read an article on a website it my ISP would start by increasing the speed down to 150 Mbps and that in some areas what was already available.

  That of why I unplugged my modem and plugged again after a 2 minute order to restart/reset and hoped for greater speed.

  When I used several speedtesters (speedtest.net, my ISP speedtester, speedtest.nl, etc.), all came to the same result, approximately 90 Mbps down and 12 Mbps to the top.

  Yesterday, I did the test on 2 separate wired computer (HTPC and desktop).

  After connecting my HTPC directly to the modem and the test I got good publicity (120 Mbps down) and 12 Mbps speeds upward.

  Therefore, it is certainly connected to the router.

  Today, I also tried by Ookla's speedtest.net on my S5 Galaxy with 5G wireless and got the same bad results as with the wired connection (90 Mbps down) and 12 Mbps up.

  I am also on a channel that is not occupied by another user.

  I also noticed that the firmware version higher on the R7000 support site is 1.0.4.30, but when I look in the upper right of the router web INTERFACE it shows the version of the firmware V1.0.5.48_1.1.79.

  How is that possible?

  In addition next to the Advanced Settings tab, there is a message that a new firmware is available.

  When I click on this message the router tries to connect to the server to download the Netgear firmware, but after a few seconds it told me that there is no new firmware available.

  I read here on the forum of others with similar problems and tried to revert to a lower firmware version.

  But I could not find an answer to this version referred to a firmware that works best.

  My questions:

  (1) what would be the first thing to try?

  (2) when to return to a previous firmware, what is the best firmware choose?

  (3) what is the correct procedure for the recovery of firmware?

  P.S. for your upload and download QoS information is always off.

  Indeed, the RAM has solved the problem.

  P.S. I accidentally marked the answer of Tarund as the answer to my question.

  Can you please remove that?

• Airport Express, Time Capsule and Airport Express using the same network

  Just moved into a new House and this is what I install.  I have 7 Port wired into the House.

  Closet of network in the Garage:

  • Cable modem
  • Airport Express
  • netgear switch 8 ports
  • It works pretty well.  All my wired connections work fine.  Wireless is quite good but cove not enough of space in my house.

  Think about adding my airport express capsule of time in my office - plugged into one of the hard wired connections.  Who works AND let me wish the WIFI?

  Thank you!

  Yes fine, assuming that first test you the Ethernet port in the office by connecting a computer (with WIFI disabled on the computer) using a spare Ethernet cable runs to ensure that the computer can get a good connection in this way.

  Put the airport Time Capsule to create a wireless network that uses the exact same wireless network name and password in your existing network. Apple installation "Wizard" automatically configure airport Time Capsule in the correct setting of the Bridge Mode for the device.

• You try to run the scan mode and mode interface fpga at the same time is causing errors

  I'm reading a 9236 9237 and a 9215 with the scanning engine and read from two 9211 modules with the fpga. It's because I need to acquire to 200 Hz with the 9236 9237 9215 but maximum rate of the scan engine is limited by the slower module in the system, which in this case is the max of 15 hz the 9211.

  So to use both interfaces (scan engine and fpga), I followed the percisely given in this article for instructions.

  1. the project has created and added the peripheral crio using the interface of the scan engine.

  2. Add the target fpga and drag and drop the 9211 inside modules

  3. has created the fpga in interface file with and compiled with no error.

  4. interfaced with the file fpga at almost exactly the way the sample project of "getting started with 9211' by using the engine of analysis in the interface with the other modules.

  5. after the errors to discover that I created a VI that tests for just the portion 9211 code (called "thermocouple FPGA method Test.vi")

  The data returned by the interface fpga was nothing else than zeros on all channels, even if thermocouples were hooked on some of them. (all zeros as entries in the convert temperature vi gives-410, 6160 degrees F, if you happen to have the material to try this.)

  I get the following error from the open fpga vi reference:

  This should not be the case.  9211 data will not update with each sweep, but you should be able to run the scan faster than 15 Hz without problem.  Do you have specific issues with this?

  You can try making sure that the chassis is set to mode Interface FPGA and the setting is deployed.  I wrote that article that you referenced says will select the deploy option later and not explicitly speak to deploy the chassis later.  Run a VI with a reference open FPGA vi not automatically deploy chassis settings if you need to do it explicitly.  Try the following steps.

  1. right click on the frame element and select Properties.  Make sure that the Interface FPGA option button is selected. \

  2. right click on the frame element and select deploy.

  3. repeat your VI.

  The data returned by the interface fpga was nothing else than zeros on all channels, even if thermocouples were hooked on some of them. (all zeros as entries in the convert temperature vi gives-410, 6160 degrees F, if you happen to have the material to try this.)

  The likely cause of this error is that the setting of the FPGA Interface on the chassis has not been deployed.  If the chassis is still Mode Scan fixed personality bitfile will be loaded on startup and the FPGA will be locked.

  I'm sorry that you have had difficulties.  Assuming that I'm wrong about the source of your problem, it seems we have to update less than Ko to include the deployment step.

• Synchronize the pci-6254 and cDAQ-9174

  Dear all,

  I hope you enjoy!

  I intend to synchronize two cDAQ-9174 chassis for an application where I need to acquire data of 8-Thermocouple, voltage 3, 1-Full bridge (strain gauge) and channel 2-meter at the same time. This enforcement action is based encoder (quadrature with 1024 ticks per round) and I need to acquire data very fast and synchronized in all channels!

  I bought the material and I'm going to set up 3-voltage channels in NOR-9221, Thermocouples-4-NOR-9211, 1 strain of NOR-9237 and 2-meter gauge in NOR-9401 first cDAQ-9174 chassis Modules. I will then put remaining Thermocouples-4 in the second cDAQ-9174 chassis.

  The question is whether it will work?

  If Yes! Then, kindly help me on how to have synchronized it data from these two cDAQ-9174 chassis with all such modules as mentioned above?

  I hope someone can help me with that and can guide me to do this task! I'm using Labview 2009 with NOR-DAQmx 2009

  Kind regards!

  Tajim!

  A few comments after looking at your code:

  I don't understand what you're doing with cancel in the task of counter.

  You try to use the encoder as your sample clock?  You can do it for the module 9221 and NI 9211, but it will not work with the NI 9237 as I mentioned above.  You can move the NI 9237 in a separate task and from there, you have a few options depending on how you want to synchronize.

  How many times you expect to get your clock on cDAQ2Mod3/PFI0?

• Conversion gain proportional and derivative to significant stiffness and damping units PID

  Hi all

  I appreciate if someone could give some insight on how to convert the proportional gain (Kc) and secondary gain (Kc * Td/Ts) in meaningful units in terms of stiffness(Nm/rad) and damping (Nm/rad.s)

  I do a position with PID (FPGA) .vi control... I only perform a check of the PD.

  My process variable is the position of encoder in charges.

  Thank you!

  PS: To make things more confusing (for me), these gains are represented by a number fixed point in the express PID (FPGA) .vi and they are normalized too.

  Hi Nathan,

  Thanks for your reply. I gave her a reflection more and that's what I found.

  My process variable is the location information of the encoder, which is the unit of account. My controller, multiplies the P position error, more the rate of change of position time D and it sends to the engine as a control voltage. It is:

  output of the PD controller = control voltage of the motor amplifier = P * (Pos (setpoint) - Pos (process variable)) + D * d (Pos) /dt

  So my P gain has the unit of volt/count. To convert this to N/m or (Nm/rad), I need to know what the relationship is between 1 volt for the engine and the torque generated (1 volt = 1 * K1 amp = 1 * 1 m end * K2 Nm). I also have calibration, namely the relationshio between 1 County of the encoder and displacement of end effector (1 count = K3 * rad)

  Knowing these values K1, K2 and K3, I can convert my P gain to a setting of significant rigidity in terms of N/m or Nm/rad for the torsional stiffness. Similarly, the D can be converted into a unit of depreciation.

  It's my understanding. If anyone has a comment on this approach, I am happy to hear it.

  See you soon!

• 9237 & 9205 with 9178 chassis sampling rate problem

  I have two 9237 and installed 9205 on 9178 chassis. In order to acquire data at the same time, all the 9237 and 9205 use the 9178 chassis onboardclock. But when the sampling frequency is 20000 Hz, 20000 points just takes less than a second. When the sampling frequency is 10000Hz, get 10000 points takes 1 second.   Why does this happen?

  A 9237 use a channel, another 9237 use 4 channels, the 9205 use 3 channels (differential).  And manual brand 9178 slightly confused me, the frequency of onboardclock MHz 80?

  Looking forward to your help. Thank you.

  By default the 9237 derives its clock dividing down from his own time of 12.8 MHz (see specifications) base.

  12.8 MHz / 256 / N

  Where N is a whole 1 to 31.

  10 kHz is achievable (12.8 MHz / 256 / 5), but it's not 20 kHz (12.8 MHz / 256 / 2.5).

  The driver will round up to the next frequency, which is be of 25 kHz (12.8 MHz / 256 / 2).  25 kHz, we would expect 20 k samples to be acquired in 0.8 seconds.

  Best regards

• How to record data every second and present them in a table

  I got a set of data of an instrument and the acquired data to an AI, and I want to compare them in a table.

  In the future, I want the table excellent export file.

  Could someone help me with it?

  No, you don't understand. If you have a flag outside the while loop, it will be not updated before the end of the loop. It must also ensure that the data type is correct when you move outside of the loop and I don't think that you did exactly what meant Dominic. I suspect that you wired out of 2D data, and that would be a mistake.

  Below is a simple shift register to create the data for the table.

• You can use NI 9237 for the LVDT readings

  Dear comrades,

  I wonder if I can use NI 9237 and NI 9945 to get the reading of an LVDT. The interest is to measure the movement using Solartron DC Miniature LVDT.

  In our laboratory, we have NI 9237 and NI 9945 and I would get your advisor if it would be good enough to measure the movement of an LVDT.

  Thanks in advance.

  Hi Gtharm,

  For the Solartron DC Minitature LVDT transducer already includes oscillator, demodulator and filter which alow the sensor to accept the input voltage and provide a DC output from the position. Therefore, instead of using the bridge according to the measure such as the NI 9237 or NI9945 modules, you must only input I take the input voltage.

  The LVDT voltage range would determine which modules HAVE you need to take the measure. Of the specification, you need to at most 100 Hz to get the signal from the probe safely.

  I hope that this help mate.
