Of course, please check the file section

In createwdqfile.zip, two sample files are included:

GenerateWdqfile uses writedatafileII control
GenerateCalculatedwaveform uses writedatafil control

Per user request, the waterfall display in audio spectrogram program is now
resiziable

http://www.ultimaserial.com/UltimaSound.html

Also, a sample audio file to display the world "Hello" in frequency domain is
added

The new uMeter add-on seems to have replaced the old Meter and Alarm, but no
longer allows me to set averaging length and averaging mode.  This is important
to me as when teaching I keep a window open for current load and a window for
peak load.  Is there a way to restore this function or get access to the older
version of the program?  Thanks.

The old meter is from dataq, not ultimaserial, and it has been discontinued. I
will see if I can find it somehow

Hello everyone,

I'm trying to use the 158U to add computer automation to an engine dyno and I
have a couple questions.

First let me say that the ultimate serial has been wonderful to work with. I was
able to quickly review the samples and get my VS2008 project up and working.

Does the ultimate serial have any sample frequency limits like windaq lite?

Should I poll with a timer or use events to retrieve samples?

I need to get engine RPM. I built a little hall sensor circuit and have tested
it at my desk. Do you think I will be able to read RPM up to 7000-8000 Rpm using
ultimate serial?

I'm a programmer by trade but I'm a little rusty on my electronics.

Thanks for any help with this project.

Sorry, but ultimaserial doesn't have frequency reading

I used a Freq to voltage converter LM2917 in my Dyno.

Contact me directly for further info.

marshland@...

Thanks for the reply. I'm programming in Visual Basic .NET using Visual
Studio. The UltimateSerial control is working fine in my program but at
high RPM's it is not accurate. I don't think the computer can keep up.

Someone suggested I use a LM2917 chip to convert to volts. I think this
may work.

I will let you guys know.

Hi,

I'm new to the group, new to Ultimaserial and new to DATAQ products as well
(also fairly new to programming in VB.NET).

I'm not sure how to word this question, so I will show what I AM doing, and then
what I would LIKE to do, and any help would be greatly appreciated.

Currently doing successfully in VB 2008.

Starting to monitor my DI-158U analog channels 1 and 2.

  SampleRate = SampleRateBox.Text
  AxUltimaSerial1.ChannelCount = 2
  AxUltimaSerial1.set_PChannel(0, ULTIMASERIALLib.enumChn.Ch01_SE)
  AxUltimaSerial1.set_PChannel(1, ULTIMASERIALLib.enumChn.Ch02_SE)
  AxUltimaSerial1.Device = ULTIMASERIALLib.enumDeviceType.DI158
  AxUltimaSerial1.CommPort = ULTIMASERIALLib.enumComPort.USB
  AxUltimaSerial1.SampleRate = SampleRate
  AxUltimaSerial1.Start()

Open MS Excel

   oExcel = CreateObject("Excel.Application")
   oExcel.Application.Visible = True
   oBook = oExcel.Workbooks.open("C:\testcode\template.xlsm")

Send Info from DI-158u to Excel

   Dim v(1, 199) As Short
   v = AxUltimaSerial1.GetDataFrame(200)
   oSheet = oBook.Worksheets.add
   oSheet.Name = "Working"
   oSheet.Application.Visible = True
   oSheet.Range("A3").Resize(200, AxUltimaSerial1.ChannelCount).Value =
oExcel.Worksheetfunction.Transpose(v)
   oExcel.Run("macro") ' VBA macro to process the data

Stop Monitering DI-158u

   AxUltimaSerial1.Stop()


My Problem is that if I want to perform another test, the DI-158 still contains
the information from that one in its buffer and clearing the array does no good
because it gets repopulated with the same stuff.

What I would like to do is upon hitting start button:

1: Start Monitoring DI158u analog channels 1 and 2
2: open excel
3: Wait until the buffer has 200 items per channel
4: send the 200 items to excel
5: launch the macro
6: stop monitoring the DI 158u AND clear the buffer so the next time I do it, it
has fresh data.

step 3 and 6 seem to be the areas I'm not getting. Any Ideas? Thank you for
reading through this far and for any help you may be able to provide.

(I did not include my entire program in this post, I know it looks like I'm not
declaring variables, etc, but the code I did include is working, I'm just trying
to figure out how to do something differently)

Several options:

1) Based on the sample rate, add delay between each GetDataFrame, which simply
provides you with the latest batch of data

2) Make sure AvailableData property has enough data, then use GetData (not
GetDataFrame), which returns only the new data

Besides the different text colors when the reading passes high or low limits,
now Windaq meter can output alarms via D3 and D3 of the device's digital port

See http://ultimaserial.com/wmeter.html for more detail.

FFT II and Spetrogram II are the second generation of the Windaq add-on FFT and
Spectrogram, with multiple FFT sizes, 1024, 2048, 4096 and 8192, and higher
resolution

http://www.ultimaserial.com/wdspectrum.html

Per user request, the scale of the waterfall is now adjustable

Place the mouse cursor in the top FFT waveform chart, drag the waveform up and
down, left and right click to reduce and increase the gain, and the waterfall
will follow it

Also added is AutoSet button. Like the similar button on a scope, single click
on this button will bring the signal in sight

For a video tour for the new features of spectrogram II, please visit

http://www.youtube.com/watch?v=YBk87NYZ1VA

UltimaWaterfall now accepts up to 4096 data points across the spectrum

Spectrogram II uses the above new features to allow expansion of its FFT
waveforms

Please download the latest and report any bugs

Hello
I would like to learn how can I use when one of the digital channel is input,
the other one is output. I searched in ultimaserial web site and I found some
codes but it is not clear for me...

I know following code line is used for that.

ultimaserial1.SetDIODir(0);

whats mean of 0. how does it express for digital channels I/O....?
and for example, how can I appoint when digital channels 1,2 are input and 3,4
are output.

thanks a lot for your support

See http://www.ultimaserial.com/standard.html#SetDIODir

Each bit in the direction register controls the direction of corresponding
digital I/O bits

For example, bit 0 controls the direction of digital I/O 0, bit 1 controls the
direction of digital I/O 1, bit 2 controls the direction of digital I/O 2...

So to make digital channels 1,2 as input and 3,4 as output, you need to set
digital IO direction register as 0011 (binary), or 3

Hallo,

there are 3 digital i/o in this system. Can I use one as digital output and if
so, how do I set it up in a VB6 program?

Thanks in advance
Olof

DI-194RS has no digital outputs

Okay, I misunderstood the specification from dataq (say´s two digital inputs and
one output, however only to be used intenally??).

Would it be possible to use the the SquareWaveOutput on D2? I have noticed a
different voltage on this pin when toggling true/false?

Thanks in advance
Olof

The Labview example in http://www.ultimaserial.com/lv8tutor.html has an error,
so that it only works with DI-148.

Now the bug is fixed

Not really

Here you will find a Step-by-Step tutorial on how to create your own VI for
Windaq Starter kits

http://ultimaserial.com/lv8tutor2.html

1) Windows is now sizable, up to 4000-pixel wide
2) FFT size increase to 16384

http://ultimaserial.com/wfftii.html

Update on Windaq add-on FFT II & Spectrogram II

     * For FFT size of 1024, all 32 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
     * For FFT size of 16384, up 3 channel can be enabled in Windaq

See http://ultimaserial.com/wdspectrum.html

Does anyone have developed a Labview VI for the Agilent 4294A? I am having
issues to display the data and save it (if I do it too fast it locks up the
instrument). Any help would be greatly appreciated.

tks

Windows 7 appears to be giving me fits using the drivers with C#. Anyone else
have a problem, or anyone know of a linux version?
