Yet another dual monitor question (they seem to be popular at the moment):
I would like to have a dual monitor setup with a laptop (ie, use the laptop
screen as the first screen and an external monitor as the second screen).
Can anyone offer comparisons between such a setup and a desktop system
If the communication you need is very simple, like e.g. just to get X
modbus register values from the unit then opening a serial og tcp/ip
link and sending a fixed string to the unit (assuming it's a
slave...is it?) will do the trick. Then you'll get back a string that
is fairly easy to decode

QSI Corp, www.qsicorp.com, makes a variety of displays, that are
controllable via RS-232 or ethernet. A number of these models already have

In my last answer, I neglected to mention that QSI Corp is the one that has
been displaying displays at NI Week for the last two years.

No problem Dargar!
It's not to late to recover.
Please post a new Q worded the way you intended. Then answer your own
Q and include a link to this thread.
That way other developers in the future will be able to find the
solution using the techniques you used in your preliminary search.

Hi there!
The Call Library Function Node has a undocumented upper left input
wire, left of the output wire, corresponding to the return value, if
any.
It looks like I can use this wire to influence the order in which
different Call Library Function nodes execute. Is this a documented

I am working on a project and i have got the following query.
i have a front panel with lot of objects like knobs,dials,push buttons

the entire panel will be the console to the user and as he changes the

positions of the objects their values will be written in to a file.

Just a quick question to make sure I understand how quadrature
encoders work.
On the encoder disk, we have channel A and B.
Now if I have an encoder with 2000 counts per revolution does this
mean that:
1) every rising and falling edge of channel A and B represents one
count of motion?
2) there
Does anyone know of any display (preferably touchscreen, but not
necessarily) that can be controlled over RS232 interface (rather than a
video board or chipset)?

Another way of adding items to your palette is by saving the folder
which includes the dir.mnu file and all the VIs into your
\labview\user.lib directory. LabVIEW will automatically update its
user library palette next time it launches.
There are more explanation on this behavior (palette-

I most often hide error indicators until there is an error. To do
this, I have to use an unbundle to get the T/F from the error cluster
and wire that to the visible property node of the error indicator.
How about allowing one to wire the error cluster directly to the
visible property, the same
Frequency to voltage into an analog input might be a good approach.
There are F/V converter chips availiable, and quite a few off the shelf

Thank you for your help. I read my post again and I admit that it was
really confusing. So, I will try to make my question more clear.
I am trying to make a multiplexer using IFFT. Input signal is array of
complex numbers which represents complex weight for corresponding
sinusoidal basis function
Hi,
I am using LabView 6.1 in compaq tablet PC. I am having problem with
moving the icons.sometimes wiring the icons also does not work.
I just want to ask you guys if this is a bug and if it's been fixed,
where can i find the updates. If it's very naive of me to expect such
thing, please
i have a data set with XYZ points and an 8 bit intensity value (0-255)
which i would like to overlay on the 3D plot. Is this possible with
the 3D surface graph in LabVIEW?
If I subtract two waveforms and feed the resulting difference waveform
into an RMS function, I get the RMS of the amplitude errors between
the two waveforms. A smilar RMS error calculation for the time axis
is required. Is there an existing function that would do this, or how

The positions of the front panel objects can be read and set using
property nodes. These positions could be read from a file at program
start and written at the program termination, however, how do you plan
to have the user change the position of the control during run-time?

Goodness, I didn't mean to start a thread on the general issue of
error display.
I must be a bad designer because I do just what you are saying is a
no-no, which is to leave a small amount of real estate blank. The
error indicators stay invisible until an error condition occurs, so

Under normal conditions a time signal will be Real while the spectrum

How do use labview to send a service request through gpib?
Create a local variable of the control to set its value.
Im assuming you mean position as in dial postion, not the actual object position on
the panel.
