WinDaq Add-ons

  


 

 

 

What is WinDaq Add-ons?

WinDaq Add-ons add new features and functions to WinDaq software from DATAQ Instruments. 

With WinDaq add-ons, even the low-end products can employ many powerful functions found exclusively on expensive high-end packages, for example, SMS and email-enabled alarm, calculated trigger mode, derivative trigger mode, calculated channels,  spectrum display and closed-loop control. 

DATAQ Instruments recommends our WinDaq Add-ons to all WinDaq users

Minimum Revision of WinDaq Acquisition Software

3.16 and please make sure you have the latest WinDaq add-ons.

3.52 if you wish to employ the batch operation.

WinDaq addons operate and record data at WinDaq's hardware scanning rate which can be set to the maximum device speed at any version of WinDaq, thus the recording speed limit imposed by WinDaq/Lite has no effect on WinDaq addons. For example, you can't use WinDaq/Lite to record to disk at sample rate of 1500s/s, but you can display the waveform at 1500s/s, so calculated channel recorder (WinDaq addon) can easily record to file at 1500s/s. A factor that may limit WinDaq addon's performance is the computing power of your computer.

Latest Version of WinDaq Add-ons:

See WinDaq Add-ons Update Log

                            Add-ons for WinDaq running DATAQ devices, Transonic Flow meters and Dataforth isoLynx SLX718

To Use WinDaq Add-ons

  1. Confirm WinDaq 3.16 or higher is installed on your computer

  2. Install WinDaq add-ons. 

  3. Restart WinDaq, and you will find the WinDaq add-ons integrated into Windaq->View->Add-ons menu (see the screen capture above).

  4. Intelligent Channel Selection: Highlight/Select a channel in WinDaq and fire up the WinDaq add-on you wish, and the WinDaq add-on will use the selected channel as its default channel. 

  5. Do not change WinDaq's configurations while WinDaq add-ons are running, or some add-ons may terminate.

  6. If you experience trouble with WinDaq addons, please email us the configuration files of WinDaq add-ons a long with TPDATAQ.INI in Windows directory.

  7. Like WinDaq recording software and WinDaq Waveform Browser, WinDaq addons can not store or open files stored under folders with UNICODE names. For example, if you create a folder on your desktop and name it in any language other than English, you can not store .WDQ files to that directory, nor open .WDQ files stored in that folder.

 

Retainable configuration

  • Many add-ons retain their configuration on exit

  • To use this feature, you should start the add-on from the SAME WinDaq logical channel. For example, highlight the second channel on WinDaq, start the add-on, set up the add-on then exit. Now the configuration is saved in a configuration file associated with second channel. You can have multiple configurations for the same device, each configuration associated with a different WinDaq logical channel. To recall the configuration stored associated with logical channel 2, highlight the channel on WinDaq, start the add-on. 

  • The logical channel mentioned above is not the physical channel, it is the logical order of a physical channel listed in the channel selection box. For example, we have two WinDaq setups, one with physical channel 1,2,3,4,6,8, and the another with physical channel 6,7,9,10,14,15. If the add-on configuration is associated with the second logical channel, then highlighting physical channel 2 from the first setup then start the addon will be the same as highlighting physical channel 7 then start the addon.

WinDaq Add-ons Listed in Alphabetical Order:

  • Add-on Batch Editor  (ID=7040, Menu Name=!Add-on Batch Editor)

    Create and Edit a batch startups for WinDaq add-ons. You can specify the channel each add-on uses. 
      

       
    • add an add-on from the available list to the auto startup group. Double click on an item in the available add-ons group will render the same result
    • remove the highlighted one from the auto startup group
    • change the channel associated with the highlighted add-on in the auto startup group. Double click on an item in the Auto Startup group will render the same result. Please note, the channel has two possible meanings. Must read: The mystery of channel index!
      1. The logical channel being used by the Add-on, such as the FFT II. 
      2. The retainable configuration # being used by the Add-on. For example, MagicMeter's Advanced Math module saves its retainable configuration to a file section associated with the channel number. 
       
    • test drive the add-on highlighted in the auto startup group
    • accept and save the batch
      • Please note that the batch configuration is associated with each hardware configuration setup. For example, a batch configuration for DI-149 will NOT be applied to DI-720. 
      • Business Pro license is required if more than two add-ons need to be started by Batch operation.
          
  • Add-on Batch Start  (ID=7041, Menu Name=Add-on Batch Start)

    There is NO GUI for this add-on.
    It starts the batch created by Add-on Batch Editor. If you have WinDaq rev 3.51, , you don't need to use this utility, for WinDaq will automatically invoke the batch operation. In the above example, three Gauges, two magic meters, digital output and calculated analog output will be started. Add-on Batch Start is normally installed as a hidden add-on. Please use Windaq Add-on Manager to add it to Windaq's menu if you wish to invoke it from WinDaq Acquisition Software's add-on menu

    Business Pro license is required if more than two add-ons are need to be started by Batch operation.

    How to configure WinDaq to retain its position and dimension? 

    To fully take advantage of the batch operation, especially channel-related displays such as Magic Meter and Gauges, it would be desirable to have WinDaq come up at the same position and dimension whenever it is started.

    The height and width can be retained by WinDaq->File->Save Default Setup

    The position of the upper left corner may be specified in the following fashion

    1. Check WinDaq-> Edit-> Preferences-> Exit on Full
    2. Invoke WinDaq-> File-> Save Default Setup
    3. Uncheck WinDaq-> Edit-> Preferences-> Exit on Full
    4. Invoke WinDaq-> File-> Save Default Setup again
    5. To disable fixed positioning, move the window to the upper left corner and repeat steps 1 to 4    

     

  • Add-on Manager (ID=7016, Menu Name=!Add-on Manager)

    Use this to manage the add-on menu, removing unused add-ons from the menu



    Note: 

    • The new add-on menu takes effect on the next start of WinDaq acquisition software
    • The license takes effect on the next start of WinDaq add-ons
    • Menu items are sorted in both  list boxes
    • Multiple selection is supported (see above image)

  • Advanced Event  (ID= 7010, Menu Name=Advanced Events)

    Advanced Event adds audio capability to the commented event marks feature of WinDaq acquisition software.

    Instead of typing in your text comment for events while recording data stream in Windaq, you may record your audio comment via the microphone of your PC!

    Windaq add-on: Advanced Event

    Features of Advanced Event
    • Support any microphone connected to your PC, as long as it is designated as default microphone input.
    • Record hours of audio comment, and play it back in sync to the waveform with WWB Event Navigator
    • Mark both the moment you start typing the text comment and the moment you push the insert button.
    • If long (hours) audio comment is recorded, and the synchronization between comment and audio comment is important, due to WWB's time stamping method, it is recommended to start recording first, then pause and resume the recording right before inserting the audio comment. 
    • Please do not embed period in file name, for example, "My.Test.Wdq", or WWB Event Navigator will not be able to open it.
    • Until WinDaq enters record mode, you can't insert any verbal/text comment
  • Advanced Analog Triggered Recorder (ID=7032, Menu Name=Advanced Analog Trigger)

    This add-on uses calculated result to provide trigger mode for all Windaq-based instruments, including WinDaq Starter kits

    Analog Derivative Trigger Mode

    • Advantage and Applications
      • Huge pre- and post- trigger buffer
      • Industry-first Analog Derivative Trigger Mode, e.g. dV/dt>30. For example, one can trigger on a glitch riding on a slow moving signal swinging from rail to rail
      • Trigger on combination of conditions, e.g. Channel 1>0.2 and Channel 2 <3. This is especially important in test that has multiple variables
      • Analog Calculated Trigger Mode, e.g. Channel 1 * Channel 2 >40. For example,  the power consumption based on the readings of voltage and current
      • Provide trigger mode for all Windaq-based instruments, including WinDaq Starter kits. 
      • provides direct Excel link for Business Pro License users
        • Supports both 32-bit and 64-bit version Microsoft Excel 
        • You need full version of Microsoft Excel to use this feature. Click here to learn more about this requirement.
        • Live streaming to Excel when trigger condition is met!
        • Please make sure the sum of pre-trigger length and post-trigger length does not exceed your Excel's row limit
    • Recording capability
      • Auto increment for WinDaq file name 
      • Up to 8000 event-marked trigger captures per file
      • File size: up to 4GB
    • Performance and Features
      • Maximum throughput rate depends on many factors.
      • If there is no trigger for more than 3 + (pre-trigger period) + (post-trigger period) seconds, the display turns into free-run mode, just like a real scope's trigger mode
      • Here are some suggestions on how to maximize the performance:
        • Enable as few WinDaq channels as possible. 
        • If the sample rate is a constant, use a constant in the equation instead of referring to #@
      • All important settings are retained between sessions
      • Trigger States and their indicators
        1. Blue: Filling up pre-trigger buffer
        2. Yellow: Waiting for condition to be FALSE first
        3. Green: Waiting for condition to be TRUE
        4. Red: Filling up post-trigger buffer
    • Chart Features
      • Plot all (up to 16) WinDaq channels
      • Sizeable Chart
      • Trigger Indicator
      • Use mouse wheel or buttons to zoom in/out
    • True math expression with many predefined operators and functions
      • Must read: The mystery of channel index!
      • Operators include: +, -, *, /, ^, %, &, |, !, >, >=, <, <=, !=, ==
      • Functions include: abs, floor, hex, round, if, avg, bin, log, sqrt, ceil, log10, sum, max, min, acos, asin, atan, sin, sinh, cos, tan, cosh, tanh
      • To use the reading from a channel, use #n. For example, #0 is the reading from the first enabled channel in Windaq
      • To access the sample rate, use #@. 
      • You can use earlier readings to form a more complicated math expression. To do so, add a letter after #, and alphabet order of the letter represents the delay, such as:
        • #0 is the reading from channel 0
        • #A0 is the reading from channel 0, one scan earlier
        • #B1 is the reading from channel 1, two scans earlier
        • Readings from up to 26 scans earlier can be used, for example, #Z0
        • For example: use ( #0-#A0)*#@, or  #0-#A0, to form a two-point derivative
      • The math equation parser uses standard English (United States) notation without the present of digital grouping symbol, the decimal point must be "." (period) instead of "," (comma). If your Regional and Language Setting is not English (United States), you may need to adjust it

     

  • Advanced Triggered Storage (ID=7039, Menu Name=Advanced Triggered Storage)



    Comparing to WinDaq's single-trigger counter part, this add-on uses calculated result to provide two trigger points for all Windaq-based instruments. For example, add a start trigger of "#0<7" and a stop trigger of "#0<5.1", it can be used to record a battery discharging curve like the one shown below

    • Advantage and Applications

      • Trigger on combination of conditions, e.g. Channel 1>0.2 and Channel 2 <3. This is especially important in test that has multiple variables
      • Analog Calculated Trigger Mode, e.g. Channel 1 * Channel 2 >40. For example,  the power consumption based on the readings of voltage and current
    • Recording capability
      • Auto increment for WinDaq file name 
      • Up to 8000 event-marked trigger captures per file
      • File size: up to 4GB

  • Alarm (ID=7023, Menu Name=Alarm)  

    This powerful utility provides closed-loop control for Windaq, with supports for both simple logic and more complicated math expressions. Due to its better replacement Digital Output II, Alarm is normally installed as a hidden add-on. Please use Windaq Add-on Manager to add it to Windaq's menu if you wish to invoke it from WinDaq Acquisition Software's add-on menu

    Simple Logic Mode 

    • Support various combination of alarms 

    • All settings are retainable 

    • Both digital and visual alarm outputs

    • Monitoring rate up to 60Hz, depending on OS and workload

    • Conditions can be changed on the fly

    • Channel number is a 0-based index to Windaq's scanlist. For example, if Windaq has channel 3,4,6,7 enabled, one can enter 0 for channel 3, 1 for channel 4, 2 for channel 6 and 3 for channel 7. You may also set the channel to

      • None so that this alarm indicator will stay unchanged 

      • ALL so that the alarm will be triggered when ALL channels meet the condition (see above)

      • ANY so that the alarm will be triggered when any one of the enabled channels meets the condition (see above)

    • Please configure the corresponding DIOs on DI-71x to outputs if you wish to use the digital outputs with DI-71x (Latest Windaq and DATAQ activex installation is required)

    • Due to the limitations of the hardware, when using with 720/730 USBs, please make sure Windaq's maximum sample rate doesn't exceed 100K, and the sample rate is less than 50K

    Math Expression Mode:

    • Actions
      • Set: assign TRUE state based on the evaluation of the condition
      • Reset: assign FALSE state based on the evaluation of the condition
      • Force Set: force the output to TRUE unconditionally
      • Force Reset: force the output to FALSE unconditionally
      • Note: Majority of the devices output high TRUE, but DI-149 outputs low for TRUE
      • For Audio alarm, TRUE plays the sound file
    • Math Expression
      • Must read: The mystery of channel index!
      • Support various combination of alarms resulted from math expressions based on readings from any enabled WinDaq channel (see above image)
      • True math expression with many predefined operators and functions
      • Operators include: +, -, *, /, ^, %, &, |, !, >, >=, <, <=, !=, ==
      • Functions include: abs, floor, hex, round, if, avg, bin, log, sqrt, ceil, log10, sum, max, min, acos, asin, atan, sin, sinh, cos, tan, cosh, tanh
      • To use the reading from a channel, use #. For example, #0 is the reading from the first enabled channel in Windaq
      • Support non-English (United States) Regional and Language options
    • Advanced Math Expression
      • To use the data-window derived results, use #min, #max, #ave, #rms and #acrms to represent Min/Max/Ave/RMS/ACRMS in the expression, i.e, #acrms0 take the AC_RMS of channel 0.
      • The length of data window should be selected properly, especially in RMS or ACRMS mode, or wrong result may be generated. Hint, it should be multiple full cycles
      • Application: Robinson Helicopter company needs to conduct a rotor blade fatigue test, the normal signal is something like a sine waveform swing between 100 and 300 (real number is not used here to protect their IP), when the blade begins to show fatigue, the sine waveform will swing around a lower base line, say between 98 and 260, and at this point, the test must be stopped to prevent damage. To do that, they decide to monitor the mean value of the waveform over several cycles to determine when the test should be ended. First they establish the minimum acceptable level of the mean value using Magic Meter, which will be 200 if we use the numbers above, then equation (#min0+#max0)<0.95*200 is used to set the digital output to high, which in turn will trigger the switch to shut down the fatigue test.
    • Digital Inputs
      • To access individual digital input, use #dig0 to dig7 to access bit 0...7. Note, digital input must be enabled in Windaq's channel list. For example #dig1>0
      • To access all digital inputs, use #digx0. Note, digital input must be enabled in Windaq's channel list. 
        • According to WinDaq convention, the range for digital channel is from -128 to +127
        • For example #digx0==11
    • Audio Alarm
      • Allows selection of sound file (.wav)
      • Allow modification of alarm interval (in seconds)
    • Other Features
      • All settings are retainable
      • Monitoring rate up to 60Hz, depending on device, OS and/or workload
      • Switch-able between math expression and simple logic like the old Alarm
    • Special Notes:
      • Channel number is a 0-based index to Windaq's scanlist. For example, if WinDaq has channel 3,4,6,7 enabled, one can enter 0 for channel 3, 1 for channel 4, 2 for channel 6 and 3 for channel 7.
      • This add-on and Digital output are mutually exclusive
      • Due to the limitations of the hardware, when using with 720/730 USBs, please make sure Windaq's maximum sample rate doesn't exceed 100K, and the sample rate is less than 50K
      • Please configure the corresponding DIOs on DI-71x to outputs if you wish to use the digital outputs with DI-71x
      • Majority of the devices' digital output is high TRUE, but DI-149's digital output is low TRUE but input is still high TRUE
    • Example: 
      • Requirement
        • WinDaq has five channels enabled, Channel 1, Channel 3, Channel 4, Channel 6 and Channel 19
        • Three alarms are neeeded:
          • Digital Output 0 needs to be at high (TTL level) when Channel 1 is greater than 3.0 and Channel 19 is less than 2.1, low if the condition is not met
          • Digital Output 1 needs to be at low (TTL level) when the sum of Channel 3 and Channel 4 is greater than 19.9, high if the condition is not met
          • Digital Output 2 needs to be at low (TTL level) when the Digital input bit 0 is low and the RMS of Channel 3 is greater than 2, high if the condition is not met
          • Note: In the above statement regarding TTL level, we assume a high TRUE device (NOT DI-149!) is what we are dealing with
      • Implementation
        • We will use math expression mode
        • Two equations will be used on D0 and D1 (Digital Output 0 and Digital Output 1)
          • Set D0 When #0>3.0 & #4<2.1
            • Since channel number used in the math expression is a 0-based index to Windaq's scanlist, Channel 1 becomes #0 and Channel 19 becomes #4
            • & is the logical operator AND
            • Set is the same as forcing the output HIGH for high TRUE device (not DI-149)
          • Reset D1 When (#1+#2)>19.9
            • Since channel number used in the math expression is a 0-based index to Windaq's scanlist, Channel 3 becomes #1 and Channel 4 becomes #2
            • Reset is the same as forcing the output LOW for high TRUE device (not DI-149)
          • Reset D2 When (#dig0==0) & (#rms1>2)
            • Since channel number used in the math expression is a 0-based index to Windaq's scanlist, Channel 3 becomes #1
            • Reset is the same as forcing the output LOW for high TRUE device (not DI-149)



  • Analog Output (ID=7005, Menu Name=Analog Output)
    Control outputs via the DACs of the device, including DI148/158/720/730/740, while WinDaq is running. Due to the limitations of the hardware, when using with 720/730 USBs, please make sure Windaq's maximum sample rate doesn't exceed 100K, and the sample rate is less than 50K   

    Windaq add-on: DAC output

  • Aux Input Indicator (ID=7037, Menu Name=Aux Input)
    DI-720 series can have 8 extra digital inputs under most configurations. The extra digital inputs are from Aux Inputs. This is the visual indicators for Aux inputs.

  • Dynamometer (Dyno) Data Acquisition Recorder (ID=7035, Menu Name=Dynamometer)

    Dynamometer Data Acquisition Recorder adds the Torque and Speed channels generated by dynamometers to Windaq files in real-time. With Windaq/Dyno recorder and data logger from Dataq, one can chart and record other critical parameters, such as temperature, pressure and air flow, along with torque and speed from your motor engine torque test so that you can better understand and adjust the performance. 

    Dynamometer (Dyno) data acquisition recorder

    • Performance and Features
      • Custom configuration for dynamometer


        • Dyno Initialization contains the commands to set up Dyno. For example you can change dyno's torque and RPM ranges
        • Dyno Reading sends the request command to dyno at the rate defined in interval box: Some dyno requires read command for each pair of torque and RPM readings
          • The interval is defined as the absolute value of the number inside the interval text box
            • The minimum interval is dictated by the timer resolution of Windows. 
            • Positive number: Most modern instruments would prefer this setting. For example, if the interval is 50 ms, the Dyno Reading command will be sent out every 50ms, OD<cr> ..... OD<cr> ..... OD<cr>, where .... represents the interval of 50ms
            • Negative number: The command strings will be sent out one character at a time at the predefined interval so that a slower instrument has enough time to process the command. For example, if the interval is 50 ms, the Dyno Reading command will be sent out one character at a time every 50ms, i.e, O....D....<cr>....O....D....<cr>....O....D....<cr>, where .... represents the interval of 50ms
        • <cr> represents CR (carriage return) and <lf> represents LF (line feed)

          Note: You will need to read dyno's user manual or contact the manufacturer to determine if you need CR or CR+LF to terminate a command line. According to one user's unverified account, Magtrol's command line should be ended by CR under RS-232 configuration instead of CR+LF even though the manual clearly indicates CR+LF.

         
      • Combine Windaq channels and Torque and Speed channels generated by Dynamometers
      • Selectable sign:  positive number for clockwise dynamometer shaft rotation Torque, negative for counterclockwise dynamometer shaft rotation, or the opposite
      • The directional input for Torque Transducer Display (Model 6400 and 3410) is ignored
      • Dyno allows user configuration to change its sensitivity and range. It is the user's responsibility to set up the Min/Max value for dyno channels, or the waveform maybe outside of the chart or too weak to plot
      • Support Pause/Resume
      • Commented Event Marker at resume
      • User annotation for each channel, including Torque and Speed channels
      • Auto increment for .WDQ file name 
      • File size: up to 4GB
      • 14-bit representation for Dyno channels
    • Supported Dynamometers or Torque Displays

VB source codes are included to demonstrate  how to write a VB program to export data to OpenOffice.Calc directly   If you wish to convert the program to Visual Basic 2008 Express Edition (VBX2008),  check this out   

    Windaq OpenOffice Calc

  • Oscilloscope (ID=7008, Menu Name=Oscilloscope)
    Provides powerful analog oscilloscope like display with easy trigger management. 



    Windaq add-on: : Scope

    • Display up to 16 waveforms in any combination
    • Waveforms can be move freely within the windows for easy comparison
    • Trigger display on any enabled waveform
    • Analog oscilloscope-like persistence control helps to study the trend of the waveforms (Refer to the above screen shot for visual effect)

    • One click to copy the waveforms to clipboard
    • Click anywhere in the grid first, and you can use mouse wheel to change the scaling of the trigger channel (channel 1 in the above configuration). If you need to change the scaling for another channel, make it the trigger channel first.
  • Paced Note Taker with Excel Link (ID=7019, Menu Name=Paced Note Taker)

    Timer paced note taker allows user to record data to a  spreadsheet file or Excel at a much slower pace while WinDaq displaying the waveform at high speed. Minimum interval 0.5 second

    The name NOTE TAKER was derived from the add-on's original application, in which it logs to a notepad compatible text file. Live Excel link was added per users' request.



    • If log file extension is .csv, the file can be opened by spreadsheet program, such as Excel, immediately

    • Excel Link

      • Supports both 32-bit and 64-bit version Microsoft Excel 

      • If Send to Excel Cell option is checked, the readings will be sent to Excel immediately

  • Remote Event Controlled Note Taker with Excel Link (ID=7012, Menu Name=Remote Note Taker)

    This add-on records the reading of all channels to a text/spreadsheet file or Excel directly when the Event flag  is changed or the reading on a specified channel cross the threshold.

    Sample Application

    Automatically logs the cargo weight while it is being moved through a conveyor belt.

    Setup:

    1. At the end of the scale, add a mechanical switch that connects to the Event inputs or a pre-specified channel (a pull-up is needed in this case)

    2. Run WinDaq and this add-on

    3. The cargo will be sent to the scale through a conveyor belt

    4. The cargo will trip the switch set up in step 1

    5. The weight will be logged to Excel spread sheet as well as a specified text file (as backup, in case Excel was closed accidentaly by the user)





    • Two trigger sources
      • Event Flag input
        • Same as the push-button on DI-145 and 149
        • The EVENT flag on the most devices has internal pull-up
        • This is not available to devices running non-standard HiRes firmware 
        • For 710 series, if Event Flag is used as trigger source, the digital channels must be enabled at channel 17 by entering letter "I"  to use this add-on; For 718B(x), digital channels must be enabled at channel 9 by entering letter "I"  to use this add-on
      • Analog Channel
      • Trigger methods include rises, falls or changes.
      • Optional: software de-bouncing. In the above capture, 2 stable readings are required before entering trigger modes
    • Two trigger levels
      • TTL trigger level for Event flag
      • Any level within the range of the channel for Analog Channel trigger
    • If log file extension is .csv, the file can be opened by spreadsheet program, such as Excel, immediately
    • Excel Link
      • Supports both 32-bit and 64-bit version Microsoft Excel 
      • If Send to Excel Cell option is checked, the readings will be sent to Excel immediately
    • SMS and Email Link
      • Sends out email when an event is captured
      • Use SMS/Email Manager to configure it first
    • Since all data points are examined during the operation, it may not keep up with high-speed operation
    • Time stamp is added to every row of data, with 1 second resolution.
    • Do not enable remote options in WinDaq, or its scanning process may intercept and modify its state before we can catch it
    • Excel compatible time stamp format to calculate time difference between events, see example below:
      chn0(Volt)  chn1(Volt)  chn2(Volt)  chn3(Volt)  TimeStamp

  • Serial Output (ID=7045, Menu Name=Serial Output)
    When a trigger condition is met, the add-on outputs pre-defined text string to PC's serial port to control external devices or display, which include various devices listed under Windows Device Manager's COM group, such as USB to RS-232, RS-485/422 converter.


    • Features
      • Up to 8 condition for serial outputs
      • Supports up to COM 16, including many devices that show up in Windows' Device Manager as COM port group, such as USB to RS-232, RS-485/422 converter


      • Hold Time to suppress repeating text output from the same trigger condition. 

        • Minimum HoldTime: 0.1 sec

        • Maximum HoldTime: 3000 sec

        • Once the condition becomes false, the HoldTime is removed.

      • Trigger indicators

      • Full math capability as Digital and Alarm Output

      • &# tag to support ASCII control codes. 

        • Insert &#nn; to the string is the same as adding ASCII control code nn to the serial output.

        • For example, if you need to output CR+LF, insert &#13; to the serial output. 

    • Notes
      • Not every data point is tested against the trigger condition. The add-on is paced by Windows' timer, up to 50Hz.

  • Spectrogram (ID=7018, Menu Name=Spectrogram)
    This is the second generation the original Spectrogram WinDaq add-on based on a very powerful commercial FFT module, with multiple FFT sizes, much higher resolution and adjustable spectrum displays


     

    • Multiple FFT sizes: 1024, 2048, 4096 and 8192. Please make sure you upgrade to the latest DATAQ ActiveX if FFT generates blank results. WinDaq activex had a glitch to deal with starter kit and it was fixed recently.
      • Due to Windaq's memory allocation approach, the following rule should be observed if you wish to use this add-on:
        • For FFT size of 1024, up to 58 channels can be enabled in Windaq
        • For FFT size of 2048, up to 29 channels can be enabled in Windaq
        • For FFT size of 4096, up to 15 channels can be enabled in Windaq
        • For FFT size of 8192, up to 7 channels can be enabled in Windaq
      • DC component of the signal can be removed before FFT is performed
    • True full ADC resolution 
    • For the Spectrum display on top
      • Single click on AutoSet button will adjust the scale to bring a weak signal into sight immediately
      • While acquiring spectrum, you may
        • use the left mouse button to drag the waveform up and down
        • double-click the left or right mouse button to change the scaling of the waveform. 
        • push down the right mouse button to enable a vertical cursor to exam to the waveform.
      • Once you stop the live frequency display, you may 
        • push down the left mouse button on the chart to enable a vertical cursor and drag it around to study the spectrum
        • push down the right mouse button on the chart to enable a cross hair and drag it around to study the spectrum
    • For the Waterfall display on the bottom
      • The waterfall display follows the scaling and offset of the spectrum display on top
      • You may also click the left mouse button on the waterfall chart to enable a crosshair to show the frequency/elapsed time  
    • Regarding the update interval
      • The update interval is controlled by Windows's Timer, which is
        • 15.6ms minimum by default under Windows 7
        • 20ms minimum by default under Windows XP
      • The power of PC's CPU also determines if the minimum update interval is achievable or not
      • Actual (averaged) update interval will be displayed on the spectrogram is started
      • Actual (averaged) update interval will be used to calculated the elapsed time for the cross-hair
    • Channel number is a 0-based index to Windaq's scanlist. For example, if WinDaq has channel 3,4,6,7 enabled, one can enter 0 for channel 3, 1 for channel 4, 2 for channel 6 and 3 for channel 7. Must read: The mystery of channel index!
    • You may also click on the waterfall chart to enable a crosshair to show the frequency/elapsed time  
      • The elapsed time is of approximation only since the performance of the spectrogram is based on your PC's power
    • The frame of Spectrogram II is sizable, and the two charts will adjust accordingly  
    • Intelligent Channel Select: Highlight/Select a channel in WinDaq and fire up this WinDaq add-on, and it will use the selected channel as its default channel

Math expressions

  • Must read: The mystery of channel index!
  • Operators include: +, -, *, /, ^, %, &, |, !, >, >=, <, <=, !=, ==
  • Functions include: abs, floor, hex, round, if, avg, bin, log, sqrt, ceil, log10, sum, max, min, acos, asin, atan, sin, sinh, cos, tan, cosh, tanh
  • To use the reading from a channel, use #n. For example, #0 is the reading from the first enabled channel in Windaq
  • To access the sample rate, use #@.
  • You can use earlier readings to form a more complicated math expression. To do so, add a letter after #, and alphabet order of the letter represents the delay, Such as:
    • #0 is the reading from channel 0
    • #A0 is the reading from channel 0, one scan earlier
    • #B1 is the reading from channel 1, two scans earlier
    • Readings from up to 26 scans earlier can be used, for example, #Z0.
    • For example: use ( #0-#A0)*#@ to form a two-point derivative
  • Support non-English (United States) Regional and Language options
  • To use the data-window results, use #freq,  #min, #max, #ave, #rms and #acrms to represent Frequency, Minimum, Maximum, Average, RMS, RMS without DC component, i.e, #acrms0 take the AC_RMS of channel 0. Please select the window size carefully.
  • The calculated result is presented AS IS. To round to a certain position, please use round, floor, or ceil functions. For example, if the format ###.##  is preferred, you can use round(result*100)/100, where result should be replaced by your math expression 

The Mystery of Channel Index

If channel index number is required as user input for a WinDaq add-on, please enter the 0-based index to Windaq's scanlist. 

Exception: For DI-71x and DI-155, the digital channel always takes up the first index if it is enabled, even though it is NOT the first member in the scanlist!

DI-710, 718, 715 or DI-155 All others
Any of the following conditions is true:
  1. Digital Channel is enabled, where digital channel is noted by "I" in the channel selection grid
  2. WinDaq->Option->Remote Events is checked
  3. WinDaq->Option->Remote Storage is checked
All of the following conditions are true:
  1. Digital Channel is NOT enabled
  2. WinDaq->Option->Remote Events is not checked
  3. WinDaq->Option->Remote Events is not checked
Any configuration
0 is always the digital channel  0 is the first channel in the scanlist 0 is always the first channel in the scanlist
Example:

WinDaq has channel 3,4,6,7 and I (digital) and R (Rate) enabled. 

Since digital channel I always takes the first spot in the data stream even though it is the last member in the scanlist, one has to enter 0 for the digital channel, 1 for channel 3, 2 for channel 4, 3 for channel 6 and 4 for channel 7 and 5 for channel R .

Example:

WinDaq has channel 3,4,6,7, R (Rate) and C (Counter) enabled. 

Since no digital channel is enabled, we have 0 for channel 3, 1 for channel 4, 2 for channel 6, 3 for channel 7, 4 for for channel R and 5 for channel C.

Example:

WinDaq has channel 3,4,6,7 and I (digital) enabled.

Since the digital channel does not affect the index, one enters 0 for channel 3, 0 for channel 4, 2 for channel 6, 3 for channel 7 and 4 for the digital channel.

 

General Error Message 

If you manually remove WinDaq add-on file folder, which is C:\WDQFFT by default,  without removing the entries in TPDATAQ.INI. You will run into some of the following errors

  1. "Cannot execute C:\WDQFFT\addonlaunch.exe.EXE, WinExec returned 3." when you start WinDaq.

    Cannot execute C:\WDQFFT\addonlaunch.exe.EXE, WinExec returned 3
      

    • This is caused by the missing batch launcher to start multiple add-ons after WinDaq starts

    • You may continue WinDaq by clicking on the OK button

    • To fix the error, you may either reinstall WinDaq add-on or edit TPDATAQ.INI and remove the TOOLS section totally.

  2. "Cannot execute C:\WDQFFT\??????.EXE, WinExec returned 3." when you start an add-on, where ?????? is the executable of the selected add-on

    Cannot execute C:\WDQFFT\
      

    • This is caused by the missing add-on executable

    • You may continue WinDaq by clicking on the OK button

    • To fix the error, you may either reinstall WinDaq add-on or edit TPDATAQ.INI and remove the TOOLS section totally.
