4.   Close the InstaCal window.

Congratulations!  You have successfully installed and connected the ComputerBoards  A/D card for use with the Ariel Performance Analysis System (APAS) and are ready to use the ARIEL ANALOG program.

Subject: Computer Boards

Stan/John-

I have contacted Computerboards regarding the difficulty we encountered a few
weeks ago when you tried to install a system with a board. If my recollection
is correct, there was a problem when we used the new version of the CB setup.
CANA could not execute because the system could not find something or another.
We solved the problem by going back to an older version of theeir Install.

I cannot remember the details and the people at CB drew blanks when I vaguely
described the problem. So I need you to go thru the process of installing a
board on a system with the new CB Install and give me a detailed description
of the problems that develop. Or, should you remember, just pass this info
along to me. It appears that the bulk of our contact regarding this was over
the phone as I have almost no e-mail regarding it.

Thanks, Jeremy

Jeremy,

Yes, the interrupt problem is a problem we know about and we do go ahead and try to isolate the board to it's own IRQ.

But we still see a problem that when we first install the board in a new system by itself(video card only other card installed) the APAS analog will not see the board. This board on this computer is on IRQ5.

When I put the board into another slot and try it the program works.(board is still on IRQ5)

I then put the board back in the original slot on IRQ5 and it still works with the analog program.

Not a big problem for us, but it is consistent for the last few systems we put together.

I have installed the PCI analog board in my system & I think I understand the nature of the problems which have been encountered trying to get the PCI version of the boards working.<?fontfamily> It basically boils down to this. The board will not work properly if it is sharing an interrupt# with another board. It is easy to check this. Go to Device Manager, highlight "Computer" and click on the properties button. A listing of the interrupt#'s and the boards which use them will appear. Int #9 is where I find my A/D board. If there are other boards listed as using this same interrupt the A/D does not work. If you find another board using this interrupt go to the properties for that board and check the "Disable" checkbox. You do not need to re-boot the computer. The device should become disabled. Now try the Analog program. It should work if all of the sharing boards are so disabled. I contacted Computerboards about this & they confirmed that the board indeed will not work if there is interrupt sharing. They have a fix in the form of an updated version of CBW32.DLL. Their WEB site is currently down. I will get it as soon as I and check it out and send it off to you if the problem is solved. Jeremy

John-

Clearly a number of the settings are wrong. This is how they should be set.

Board type = CIO-DAS16/330
Base address = 300
Interrupt level =7 *
DMA level = 1
Clock speed = 10 MHz *
# of channels = 16 single ended
operation mode = enhanced
external memory board = not installed *
counter # = 0 source = external *
expansion board = not installed *

Normand-

Since the version you are running is dated 4/27/99 & the latest version
available is from 5/20/99 I suspect that you have software from before the
problem was fixed regarding sampling times.

With regards to the scaling problem with the data I am a bit perplexed. I
tested the function which generates channel conversions for the plates and
all seemed to be working properly. The only thing I can think of is that you
are bypassing the step where the software calculates the channel conversions
[volts to user units] from the various property pages of plate
characteristics. When you select Options/Plates/your plate type and you
click on "Ok", a dialog should appear which asks if you want to have the
software calculate the plate conversion factors. You must answer "YES" to
this.

It would be a help if you could collect a small file of data for me to look
at.

Best, Jeremy

Hello Slobodan Jaric,

Thank you for your message.  There are several items that should be checked
to initiate triggering in the analog module.  First, what channel is set as
the trigger channel.  This is labeled in the TrigCh immediately below the
toolbar.  When using the force plate, I usually set this to the FZ channel
as this is the applied force perpendicular to the top surface of the plate.

Secondly, check the trigger level.  This is indicated in the TrigLev field
immediately below the toolbar.  If the trigger level is set too high, the
sample will not be triggered.  Sampling can be initiated using the keyboard
by setting this value to a large negative number (-999 for example).
Ideally, you just need a value smaller than the anticipated signal to use
the keyboard as the trigger.

Also, make certain that the trigger channel in one of the active channels.
The last active channel is indicated in the LastCh entry under the toolbar.
 If for example, the last channel is set to B and the trigger channel is C,
then the sample will not be triggered.

I hope this information is helpful.  Please contact us for any additional
information.

Sincerely,

John Probe

We checked all options (different trig. channels, different trigger values,
different last channals) but the data acquisition was not initiated. I
repeat, according to the InstaCal program, the A/D board works.

Hello Petros Tsintzos and Dr. Christos Papadopoulos,

The Analog hardware/software included in your original APAS computer is based on the DOS operating system. Technology has changed drastically in the last 4 years. The current hardware/software operate from the Windows environment. Unfortunately, the DOS based hardware will not operate in the Windows environment. The Windows system requires new hardware and software.

The same is true for the video hardware. The "new" APAS computers include Digital Video frame grabbers that are not compatible with the "older" analog video frame grabbers. The JVC 9800 is a digital camcorder that takes advantage of the new frame grabber.

If you wish to purchase the current APAS with two JVC 9800, you could use the "new" computer for the video data collection and keep the "old" APAS for collecting analog data. If you wish to collect data on the "new" computer, then you must purchase the analog hardware & software.

I hope this information is helpful.

Sincerely,

John Probe

Now we strongly intereste to buy the APAS software with two JVC 9800 camcorders. We have also the 16 - channel Analog Hardware-software(connect the Kistler force plate and EMGs).

>I have some questions:

>
Answer 1
========
We do not sell the Analog Module as a "stand-alone" module.  The Basic APAS
is required for complete analog operation.  In order to sample analog data,
one would require the following APAS items.

Basic APAS (Hardware & Software) $10,000
Analog Hardware $7,500
Analog Software $1,500
============================
Total $19,000.00 USD

However, Dr. Ariel has agreed to reduce the price of the Basic APAS to
$7,500 (instead of $10,000) for your circumstances.  This means the total
would be $16,500.00 USD plus shipping charges.


>2. How many channels use this system like analog inputs?
>
Answer 2
========
The standard Analog Module is 16 analog channels.


>3. Which is frequency band of these channels?
>
Answer 3
========
The specs on the Analog module are:
16 Channel Analog Input
Individual BNC and RJ-11 Input Connectors For Each Channel
Input Voltage Ranges: �10V, �5V, �2.5V, �1.25V, 0 to 10V, 5V, 2.5V, 1.25V
Range selection: Software programmable
330 Khz Sample Rate
12 Bit / Channel Data Resolution

Answer 4
=========
The Ariel software provides extensive analysis capabilities including

Ariel Analog Module supports collection of analog data input.  AMTI,
Bertec and Kistler force platforms are supported with an additional
Real-Time COP and VECTORS programs. Force platform software also supports
two plates simultaneously.  EMG analysis software includes Normalization,
Rectification, Power Spectrum, Envelope, Spike, Integral, and Median and
Average frequency.  Data can be output to the printer, ASCII or Lotus/Excel
Worksheet files.

Additionally, you can download and/or view the Ariel Analog Software manual
