Serial to parallel converter in labview

Hi. Does anybody know how to convert serial data to parallel data using labview? I already used shift registers but it's not working.

You still need to be much clearer. LabVIEW does not have "registers". LabVIEW is a programming language, not a circuit simulator.
What is the datatype of the serial data? booleans, bits, bytes, U8, etc.
What is the datatype of the parallel data? 1D array of what? How big can it get? What do you want to do with it?
Do you get one boolean at a time and simply want to append it to a boolen array? That would be trivial. What have you tried?
LabVIEW Champion . Do more with less code and in less time .

Serial to Parallel converter in LV

Hi , as part of my project I need to decode Manchester encoded data and then convert it from serial to parallel.
Could you please help me on serial to parallel patt. How can I convert my data from serial to parallel?
Many tahnks

How are you reading the Manchester coded data into LabVIEW? What data type are you using?
The convert from serial to parallel is still very ambiguous. Are you trying to say you are taking an array of booleans and changing them into array of bytes?
Are you outputting through an Analog Output? Digital Output? How fast do we have to put a value out?

How to detect signals from serial or parallel ports?

Hi everybody!
I'm developping a p.o.s. app, and I need to detect the printer status (serial or parallel), but I couldn't find the way to do it (I'm using Text_IO). I know about using a C program, but I want to find a simpler way.
Is there any command or trigger in Forms 6?
Thank you for your help

Hi
In your setup you have a ADAM 4250 RS232/485 repeater talking with 7 instruments in a network. Each instrument have a unique address, and you can only address 1 instrument at a time. If you need more speed you have to insert more ADAM 4250 units in your system and more RS232 ports on the PC. Identical ADAM instruments may receive commands over the same communication line, but transmit data on a unique communication line. You can not use the parallel port in your setup at all. This is not a Labview problem but a hardware problem. If speed is critical maybe the Ethernet I/O Modules: ADAM-6000 series are better for your setup
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Are you trying to reduce the file size with the "Reduced size PDF" in the save as other option.
Give it a try if you haven't done it prior.
Open that PDF>File>Save as Other>Reduced size PDF.
If possible ,please share the snapshot of the error message with us so that we can have a look in order to assist you further.

Can not access serial port while upgrading from LabVIEW 6.1 to 7.0

Hi,
I built an application under LabVIEW 6.0.2. few years ago. This application uses LabVIEW serial features. When I upgraded to LabVIEW 6.1, my application was still working correctly.
Today, I upgraded to LabVIEW 7.0, mass compile all VIs and now my application can not communicate with my peripheral !!!
The program is sending the command to the peripheral. The peripheral answers but LabVIEW serial driver does not see any datas on buffer even if datas are available ... "Bytes At serial port.vi" always returns 0. I am sure that datas are available, using a COM port psy.
Does anyone has an idea?
I saw a lot of solutions in the forum, but I would like to know the best solution with minimum work, te
st, and so on ... on my program.
Regards,
Pascal.

Hi Pascal,
Which is your version of NI-VISA?
Please see the link bellow :
http://digital.ni.com/manuals.nsf/websearch/E8D86CD680B0753D86256D2C005D8EA0
The first test to be made is to test the communication with your serial port using MAX (Measurement and Automation Explorer) :
Open MAX, Go to "Devices and Interfaces", then "Ports", select COM1 (or ASRL1::INSTR). Right clic on it and select "Open VISA Session" the go the "Basic I/O" then Write data, execute, Read data, execute.
Be sure that the communication is OK. Be sure that you use the same Alias existing in MAX in your LabVIEW program.
Now, if all is OK, try to use Serial communication examples existing in LabVIEW Help>>Examples Finder. These examples use NI-VISA VIs.
If all above is OK and you
still have the same problem, try to follow these instructions :
"In order to use the old Serial Compatibility VIs in LabVIEW 7.x, you must copy the following files from a previous version of LabVIEW to the LabVIEW 7.x directory:
Replace the serial.llb in LabVIEW 7.x with the serial.llb from a previous version of LabVIEW. This file is found in C:\Program Files\National Instruments\LabVIEW\vi.lib\instr.
Replace the _sersup.llb file in LabVIEW 7.x with the _sersup.llb from a previous version of LabVIEW. In LabVIEW 6i and 6.1 this file is located in C:\Program Files\National Instruments\LabVIEW\vi.lib\platform. In LabVIEW 7.x (and 5.x) this file is found in C:\Program Files\National Instruments\LabVIEW\vi.lib\instr.
Copy the file serpdrv to the C:\Program Files\National Instruments\LabVIEW 7.x directory. This file is not installed with LabVIEW 7.x, so it only needs to be copied from a previous version of LabVIEW, not replaced."
I hope that my answer will help you.

MAX can't find serial to USB converter COM3

Hello friends,
I am using serial to USB converter for communicating the instruments.
I install drivers successfully and device manager shows COM3.
But when I go MAX 5.5 , I cannot see the COM3 port in device and interface.
Please tell me solution of this.

Dennis,
You are totally right, it was a mistake from me. We do not see com connections under data acquisition devices.
Haris115, can you tell which drivers and which versions did you install? You can see it on MAX. And which OS are you using?
I just want to be sure there is the correct compatibility.
Thank you

Are there any usb to parallel converter cables that work with iMac 10.6?

Have a Brother HL-5340D with damaged USB port, can I connect with a usb to parallel converter cable and have it work?

If you try to tweak the dock with third party software, that will corrupt the Dock preferences. Better to leave well enough alone.

It's clearly not impossible, just different than you expect. Create your playlist as you want it to appear in the Current tab (meaning don't dump every single song from your library in there, just the ones you want) and then save the playlist.

Look at save_absolute_paths_in_playlists in your mpd.conf.

Reference Library for Converting Between LabVIEW and XML Data (GXML)

Please provide feedback, comments and questions on the Reference Library for Converting Between LabVIEW and XML Data (GXML) in this thread.
The latest version of the NI GXML Library is availble in VIPM on the NI LabVIEW Tools Network repository.

Francesco, Thank you for the feedback. With this component it was my intention to make a more "terse" version of the LabVIEW Flatten to XML VI that was also supported on RT and that gave the user more flexbility regarding the structure of the parsing type definition. I think you are right that the XML parser is not compliant to section 2.11 of the XML spec. The parser does specifically looking for a #D#A and this appears to be an oversight on my part. Please confirm for me, the specifcation is saying that the XML parser should be able to recognize three possibilities as an "end of line" character: #D#A, #D, or #A. Am I reading this right?There are more efficient (and in some cases much more efficient) ways of sharing data between LabVIEW and LabVIEW: some examples are flattened binary strings and the datalog binary format. XML is slower than these optons but the upside is that it is human readable. Furthermore XML is inherently hierarchical which is convenient for complex data structures like clusters of arrays of clusters, etc. If you don't care about human readability then you are correct XML doesn't make as much sense.I will return to the GXML source code and try to fix this in the near future but I would hope that instead of creating yet another custom VI from scratch that you could reuse what I have provided for you. I included enough documentation in the source code so that users could make some modificiations themselves. The target application for this reference library was LabVIEW to LabVIEW communication. As such I documented the schema on the dev zone document from a LabVIEW perspective. It includes all the supported datatypes and all the supported data structures (cluters, arrays, multidimensional arrays, clusters of multidimensional arrays, etc.) I do see some value in making a more conventional XML spec but the time investment required didn't really line up with my intended use case. Were there any other downsides to GXML that I have missed? Best Regards, Jeff TippsSystems Engineer - Sound and VibrationMessage Edited by Jeff T. on 04-21-2010 10:09 AM

Controlling XY stage connected to parallel port using labview

Hi,
I have a XY stage which I can control using mach3 software. I want to control a signal generator, VNA and the XY stage at the same time. I have programmed SG and VNA using Labview but I am having difficulties controlling XY stage using Labview. I have never controlled an instrument connected through parallel port using labview.
Can anybody give me some ideas to start with? How do I use VISA to control the parallel port? I really appreciate your help. Thank you in advance.

Hi srms,
Since your question is related to using VISA, I would try posting your question on the Instrument Control Board. You're likely to have better luck there.

How can I do to communicate to parallel port using labview 5.0 and NT ?
Thank you in advance.
Regards,

If you are trying to use In/Out port functions that come with LabVIEW they will not work with NT. I think the AccessHW file at the following link will fix that problem:

and do some searchs at NI.com for parallel port, you should find some more usefull info.

Converting from LabView 4.0 to 8.5

I have a Pico Technology TC-08 thermocouple datalogger (RS232). It has drivers for Labview 4.0 but I use Labview 8.5, which says it can't convert the drivers. From the help pages I have understood that there is separate software that can convert from Labview 4.0 to 8.5. Can anyone tell me where I can download or otherwise obtain this software?

Hi EKY,
converted to LV7.1 - should be ok now
But: there's a "missing dll"-error. You have to check this in LV8.5.
There is also no guarantee the dll will work with LV8.5 or maybe new operating system (from Win95 to WinXP or Vista?)
Best regards,
GerdW
CLAD, using 2009SP1 + LV2011SP1 + LV2014SP1 on WinXP+Win7+cRIO
Kudos are welcome
