Read the serial number of the device in LabView COM port
Hello
Is it possible to read a device COM port number in LabView? I would like to make an initialization of the program following the right port COM of a device, for example a USB temperature reading device, and set the COM port as the correct port at the start of the main program of LabView. I want to do that, because a USB device gets usually different dedication of COM port on different computers. Our application runs on 80 different computers. A program like that would be very nice.
Can someone help me?

Another thought. It also has a place where certain standards can save you a lot of time.
You have 3 dongles by machine. When setting up a computer are these three dongles * always * assigned to, for example, com 3, com 4 and com 5.
Similarly, always check that instrument 1 is always on com 3, tool 2 is always on com 4 and 3 device is always on com 5.
This convention will also simplify debugging...

Tried not to revert to the older version of adobe reader, no serial number?
I've recently updated adobe reader without thinking. Don't keep the old version. Hate the new version, trying to go back, but it wants a serial number that I don't have. Adobe has create me an account (I have not one) where all my serial numbers would be stored, well since I didn't have an account, no serial number is stored. Clearly I had adobe reader software on my computer to update. I want just the old version back.

Name of the resource does not COM port number
Hello
When I connect computer Board, I use
ResourceManager.GetLocalManager (). FindResources("?*")
to get resource name ("ASRL11::INSTR") and use that name that I invoke
A session = ResourceManager.GetLocalManager (). Open (Name);
to get the session and get the value of the property HardwareInterfaceName of the session.
The problem is that the COM port number in the property ("Com10") of HardwareInterfaceName does not match name the resource. The COM port number is correct, that it is the same, as noted in the Windows Device Manager. But why the name of the resource 'ASRL11::INSTR', it should be "ASRL10::INSTR".
Does anyone have an idea?
Thank you

Hi all
I have a small application that consists of reading data from a serial port using the VISA READ function. The data source that I am trying to acquire the serial port is a microcontroller that sends a word or a byte (8bits). However, when you try to download the programming code in the microcontroller, the programming software backup code in the HEX file into the chip.
It's all just an explanation into the problem.
in oreder to get my application actually, I used the attached VI have not program but adds some functions for multiple purposes. The Vi works perfectly and everything works fine, but it seems that I had some misunderstanding here.
what I'm trying to understand here is why a function (hexadecimal string to number) is used for as much that I have configured everything to read bytes (8bits)
I am very confused
any suggestion would be appreciated.
Thank you
Converted to 8.5 and attached.

Re: Satellite C650 - problem with the devices connected to USB ports
Hello
Can help someone, I have a C650 and everytime I try to connect to something to him via the USB ports, it is not "found" by the computer?
The other night, I tried to get pictures on my phone but it wasn'; work and I put it down to a problem with the phone, but today I tried to install something digital crafts for my daughter and during installation it tells you to insert the thing into the USB port and click Next, when I do that he's going through a lot of "research" and said then it can not be found.
The laptop makes a beep sound as it would on an extraction device when you plug... I hope that makes sense. So I am now assuming that the problem is with my computer, is there something I can do to fix this?
Thanks in advanceSorry should add - it's like nothing is plugged at all when it is, and it happens on two USB ports, not just one...

Hello
What happens with plug n play like USB mouse device?
You are able to use an external USB mouse correctly?> but today I tried to install something digital crafts for my daughter and during installation it tells you to insert the thing into the USB port and click Next, when I do that he's going through a lot of "research" and said then it can not be found.
I guess this could be a problem with the software or drivers installed.I searched a bit and his city that he has a software is compatible with windows vista/2000/xp. Win 7 is not mentioned do not know if this could be a problem, but in your case, I recommend asking the support of this software product for some advice.
In addition, you can try to install this software once more, check whether this USB problem appears again.

My old laptop is dying. When I tried to install Photoshop elements 7 on my new laptop, he told me that the serial number is not valid. It's the same number that I used before. What gives
I think that this program is covered in the link below

You MUST use the special version and the serial number on the page, not your original drive or serial number
