• Agreement between MAX and Windows serial port.

  I use a laptop running Windows XP and LabView 8.5.  I have a variety of USB to serial port devices that I use from time to time.  In the past (from what I remember), has accepted the name assigned by Windows, and MAX (COM1, COM2, etc.).  Recently however, MAX seems to think there are three serial ports on the computer, but the tags with a little black 'x' by saying that the device is in a State of 'unknown '.  Using the Windows Control Panel, I see that no serial port is listed in the system until I have Plug one of the converters in.  When the converter is connected Windows automatically recognizes and says it works normally.  It seems that MAX does not allow me to delete the serial ports that scored because they did not add statically.

  Is there a way to clear the MAX?  This has not caused any problem I was not able to get around yet, but it should be clarified.

  Thank you.

  
  

• the NI 9871 serial ports appear also in MAX with built-in serial ports of the target - under devices and Interfaces IS NOT? NO NEITHER 9871 (Scan Interface)?

  Hi - Have cRIO

  Can someone help me get the NI 9871 (Scan Interface) work?  My two 9477 and two 9425 and 9403, function with the scanning Interface.  In MAX > software > NOR-Serial RT 3.82 > NOR-Serial 9870 and Scan Engine Suport 3.8.2 9871 BUT NOT == MAX > devices and Interfaces > series & parallel = number of Ports Com for 9871 listed?   Project, 4-port RS-485 NI 9871 is in slot1?  Any help appreciated thanks

• Using the Serial Port on the HP 50 g graphic calculator

  Hello world

  I have another question. I want to use the Serial Port on the HP 50 g to connect with another device. The device is called the MFJ-1214PC. What it does is to accept the text and commands through a 9-pin serial Port and converts the text in a Code Morse/RTTY sound audible. It also decodes Audible the Morse Code and RTTY radio signals and displays them as text on your computer. The program that controls the MFJ-1214PC was originally written for an IBM PC for the MS-DOS operating system. The HP 50 g graphic calculator meets the system requirements for the simplest version of the program. I was wondering if there is an MS-DOS emulator written for the HP 50 g, which would allow the HP 50 g to become the computer in this case, or if the program could be rewritten and brought to the HP 50 g. If it could be rewritten, programming language what do you think would be better suited to this type of application (if it is even possible?) or UserRPL, SystemRPL or Assembly. Don't forget that I'm a complete newbie with the HP50g and have never programmed with it yet. I'll include the manual of the MFJ-1214 PC as an attachment so that you won't have to look for him. Thank you in advance for your help!

  I understand (from my brief overview) out of the box-MFJ-1214PC, this offer box decoder output series computer.  The computer (50g in your case) will have the software to read message series and then convert that to an output for display.

  BartDb gave you the right answer.

  A serial cable with the correct speed level and reversing lever to manage as well as the 50G has a RS-232 signal to the outside world is the ideal solution.

  However, make sure that the output of the decoder box series package can be understood by the 50 g. aud, bits, etc.   (you have the set-top box manual, so you'll have to look that up)

  the streamsmart is not an aggregator of serial port.

  in other words, these connectors DIN of Qty 4 on the front do not accept series rs-232 input and send then to 50 G.

  I'm not an expert, streamsmart more info on these boxes is rare to find.  The probes are even more rare.

  However, I know that the 4 connectors are for the analog-to-digital conversion in the probes.  The streamsmart works as a "data logger" in which he sees the input probe, the A/D converted, then sends it to the 50G (or a computer via the USB port).

  In addition to the solution of Bart, there was another named Tiwag forum poster who created a serial cable and displayed a schematic representation of the cable.  This information can be found here:

  https://groups.Google.com/Forum/?fromgroups#! searchIn/comp.sys.HP48/serial$20port/comp.sys.HP48/ltcane1jSOw/uHyw2Ti03kgJ

  to see an example of programming to use the serial port of 50G, you can reference the following hpcalc GPS data collection program.

  http://www.HPCalc.org/details.php?id=7105

  It is written in userrpl so can be crossed with the reference of users advanced for the translation of the syntax.

  It seems that the main routine of concern for the comm to the gps is in the file "GPS >.

• Tecra M11 - 17V - identify the serial port on the docking station

  I have a laptop Toshiba Tecra M11 - 17V, which I often use with the docking station that accompanies it.
  There is a DB9 serial port at the back of the docking station, but I don't know what COM Port.

  I use Windows 7.

  In the device, COM9 Manager - COM22 are identified as Port BT (bluetooth). Com7 - COM8 are RIM Virtual Serial Port v2, COM17 is Prolific USB-to-Serial Comm Port and COM18 is USB-Serial CH340.

  I thought that COM17 or COM18 were the most likely candidates, but have not been able to get to answer using one of them.

  I connect a Psion 5 (Comms app) to him and have developed ports and the Psion 8bits, 19200 baud, no parity, 1 stop bit.

  Hello

  > There is a serial port DB9 on the back of the docking station, but I don't know what COM Port, it is

  I think you have misunderstood something wrong
  COM ports in Device Manager are virtual com ports
  There is no link between a serial port and a virtual com port.

  I have a question: what docking station you have exactly?

  I had an express port replicator and this device required an additional serial port driver installation.

• I want to detect and use the video entering via the HDMI port on the computer. I was told the HDMI port was not set, but I can't seem to find the signal or the video.

  I want to detect and use the video entering via the HDMI port on the computer. I was told the HDMI port was not set, but I can't seem to find the signal or the video.  Any suggestions?

  As Tom SC replied, you must contact the company that manufactured your computer.  In general, the ports HDMI on most computers is an out-bound port, send video / digital audio output.

  You should probably use a video capture card that can capture from HDMI source,

• Add card serial port of the Optiplex 780 desktop

  I have a refurbished Dell Optiplex 780 compact desktop computer.  I would like to add an inexpensive PCI card that has two serial ports RS-232 legacy.  The description says that it is a "PCI to serial port card".  He mentions "for 5V PCI slot only."

  I think the 780 will take this card, but I'm not well versed on the specifics of the new PCI standards.  This card will probably work?

  Thank you

  Jan

  Typical PCI cards have one or two notches, according to voltage signalling. Cards requiring 3.3 volts have a notch 56,21 mm from the rear of the card; those requiring 5 volts have a notch 104,47 mm of the rear plate.  Universal PCI cards have two notches to allow them to be plugged into two system 5 v or 3.3 volt slots.

  According to the Manual, the 780 has PCI 2.3.  PCI 2.3 supports 5 volt cards. Your slot machines are probably universal whereas they should accept a card with the notches or both. But be sure that

  An important point is that the map you saw is low profile and full height. The manual said that 780 office accept "without editing card - up to two low profile cards. If you need to pay attention to the voltage more than just.

  And the desktop version does not have a PCI-e x 1 slot, which means you need to find a PCI card.

  Another alternative could be a USB > serial adapter cable.

• Store data from the Serial Port in the buffer and then take action?

  Hello! Everyone,

  I'm new to LabVIEW and I take assistance from various videos and stuffs available online to get started with LabVIEW.

  But I have a duty, therefore needing help.

  initially I see some of the tutorial videos and learned about the LabVIEW interface, and does a little project to communicate with the Port series (receiving and sending data).

  Happens to my task.

  My LabVIEW application will send a few State request packets on my device or control and based on the response packet that I have to display values.

  The Structure of package is as

  Header, length, Op_Code, data Checksum

  There is no terminator as newline or carriage return or anything else.

  In C language, I read the data from the Serial Port, and based on the length, I conclude that I got the full package or not, and then by recalculating the checksum value, the integrity of the package is verified and then based on that Op-Code has been sent will be decided.

  (I'm dealing with hexadecimal data)

  But how can I do this in LabVIEW.
  A tutorial or any referece will be useful for me.

  1. I suggest that you learn to use Shift Registers instead of local and global variables.  They are much more efficient (memory and execution speed) and make it much easier to read the schema.

  2. you don't need this inside the loop property node.  Is there a way to configure a Serial Port to turn off the stop character.

  3. you don't need to wait for playback VISA will limit the rate of loop if no data is coming.

  4. Once you have the length, you simply read the rest of the entire message and process it at a time.  This will make things a LOT faster.

  5. you should really do this enum a def type so that you can ensure that all your enum constants have the same values.  If you need to add a State later, simply update your enum in the same place then.

  

• Add data from serial Port in the indicator series front panel?

  Hello! Everyone,
  I'm new to LabVIEW but has prior programming experience.

  I have to develop a front for my camera and this is why I need LabVIEW, data comes from serial Port, so I started internet research / LabVIEW forums and found various tutorials by the help I am able to do the part Serial Communication, but has got stuck in one thing.

  Whenever data from serial Port, it gets displayed on the indicator chain but clears quickly, but I want some data comes it does not erase the old data and new data to add with the old data.

  I read the string concatenation will work in this case, but I am not able to use it.

  Please take a look at my VI attached to this mail.

  You must use a shift register to keep your story.

  

  I recommend you go to some of the tutorials available.  They will help you a lot to get off on a lot of things like that.

• serial port after the installed DSC module problem

  Hello..

  I want to GSM(with labVIEW) and PLC interface, My PLC will work in serial port only.

  In my PC, I have 3 serial ports. before installing the DSC module in my system, I can configure the ports series all the... but, when I finished installation of the DSC module, 2 ports is not between these 3 serial ports. Before PRECAUTIONS, I can work with PLC and I can use other ports. After installation, I can't configure the serial ports... Hereby, I have attached the error with this...  Please help me soon...

  The Solution is, no need to install the VISA device drivers separately. Installing the DSC module only.

• NEX - 5N, unrecognized by the USB Ports of the computer

  I have a laptop Asus UH56e which became more and more incompatible with my NEX - 5N. Is not what USB port, I plug the NEX in, or what USB port in my 4 ports USB hub, I plug in, the camera is not recognized by Windows 7. I try to install the new update of firmware and can't even get past the first step, which is the connection to the computer. Is there anywhere I can download the driver for the NEX - 5N install on my laptop? It seems that the driver is not install from the camera, or is not recognized by Windows 7 (64-bit).

  Yes, it shows USB MTP Mode, but it does not connect to Mass Storage. By clicking import images and videos results in no new pictures or videos found on this device, despite the fact that there are pictures in the camera. Click Browse files and media then, however, shows the folder and clicking on that, I can see the image files and copy them to a folder on my hard drive. Yes, I tried to update the firmware several times, but because the camera is not recognized by the USB ports, the camera is not found by the firware update, either. Yes, I unplugged the USB hub and all other devices and also makes no difference. I don't have another USB cable, however. I have access to another PC Thursday, so I'll check then. Thank you, Glenn.

• serial port to the .csv to graphic file

  I use LV 8.0

  Hello I have attached a .csv file. I am able to read the file via the file VI I joined. But I want to make the graph of the following values.

  The .csv file will come from port series so please tell me how fo this. I have read the attached examples, but I'm not able to convert it to read a .csv file. I use a serial port.

  I searched the internet for examples, examples of availabe are on labview 8.2.so please guide so that I can continue my project.

  Thanks and greetings

  The example of "Detect the Break event" does not apply in your case. Your instrument causes a break or are you that a break is actually occurred? Doubtful. In your case, you need a loop around reading VISA. You must continue to read until you see the characters "End". Use a shift register to add characters that you receive from a string buffer, and then you can parse the string to get the numbers. You should probably also have a time-out to break out of the loop if the characters of 'End' are not detected by reading VISA. See attached example (LV 8.0) for a possibility.

• Is there a way to connect my DV camcorder to my usb port on the computer instead of a 1394 port, that my computer doesn't have?

  My Canon Elura 100 DV camcorder has a usb connection, but Windows will not recognize it when it is plugged into the usb port on my computer.  (The manual Elura says to connect it to a 1394 port)

  Hello

  According to my research, you must use the supplied canon DV cable and use it. Many users is connected it correctly with the usb port. I recommend you contact Canon support on that.

  I hope this helps.

• Backup drive is not detected by USB-3 ports before the computer

  * Original title: 3 USB ports do not recognize the 3 TB drive; USB-2 ports do.

  3 USB ports do not recognize the 3 TB drive; USB-2 ports do.

  After working for about 1 year, my Seagate 3 TB backup drive is no longer recognized by the operating system.

  The drive is connected to a USB port "SS" (i.e. USB3) port on the front of the computer.

  During the boot UEFI confirms the existence of the impulse, but Win 7 (64) does not work.

  When it is attached to a USB-2 port the drive works perfectly, but takes forever to my backup system.

  I went through the procedure to connect to other ports 'SS', but the OS will still not

  recognize the drive.

  I would appreciate any advice.
