Is there any way to connect an ipad to a ethernet cord or connection with out using wi fi
Is there any way to connect an ipad to a ethernet cord or connect with out using wi fi? Thank you
The closest you can come, without having a 3G iPad is to have a cellular mobile hotspot like the Mifi or such device, use that to get to wifi, or to tether it to a cell phone.

Connecting Agilent DSO3062A Oscilloscope with LabVIEW using USB
I am trying to connect Agilent DSO3062A Oscilloscope with LabVIEW using USB but the device is not recognized by MAX. I have installed the drivers for scope and it works fine with the scope software. The problem is LabVIEW dosen't recognize the scope. Please tell me the procedure of setting up the scope with LabVIEW 8.2. I am using Windows XP.
Hi there,
I think the issue is that the DSO3062A will not be recognized by LabView as a GPIB instrument through the USB connection. If you check out the 3000 series manual (http://cp.literature.agilent.com/litweb/pdf/D3000-97016.pdf) you'll notice on page 8 it says you can't use the USB for programming, it can only be used with their scope software. You need the N2861 module installed on the back to connect via GPIB, and then a GPIB interface to your computer. I hope that helps.

Fast low level Ethernet communication with LabVIEW
Hello, I want to read Ethernet packets with LabVIEW (an private protocol, not UDP or TCP or others). The hardware writes 40 000 packets per second. I want to use winPcap API to capture data. I’ve seen the example «packet_sniffer_project » (and others). It’s an great job. But the soft reads only 1 packet at each time (wrapper dll calls « pcap_next_ex » function) and I lose packets. With my computer, I read 25 000 packets per second. How can I read more than one packet at each time? (or all the Ethernet buffer) Thank You
MickeHi,
maybe an example that I posted will help you

Sharing ethernet connection with airport card from ( iMac 17" intel)
I have recently upgraded from a 800 15" iMac to a new 17" intel iMac - before the upgrade it would share the ethernet connection to the internet with sharing and broadcast the signal to my FW800 powerbook ( or any other mac in the house ( no problems)
Now with the new Imac set up I enable sharing ethernet connection to computers using airport ( same as before) I can see the computer ( sharing the connection) in the airport menu of my FW 800 PB - when I try and connect I get an error message ?
Looking for any tips or direction? I searched this forum ans apple support pages and did not find an answer... PB = OS 10.3.9 - Imac = OS 10.4.5Hey thanks for the welcome!
The error message said " there is an error in connecting to ..."
OK ( after just checking it again) go figure - I turned off sharing ethernet connection to computers using airport on the iMac - and turned it back on and voila! I am now connected using the PB - ??? Must have been a reset issue?
lets see if this is a solid connection...
Thanks for the fast reply!

I have a ipad 2 and it does not connect with safari using 3G
Sorry to hear you are having issues, but there are 2 ways you can print from that device.
The first one is to simply email photos or documents to your printers email address by attaching them to a new message.
The other option is to download the HP ePrint Home and Biz app from Google Play. The app is free and should allow you to print pictures and documents to the printer with ease. I have added a link below on how to get started with this app.

Which stepper motor is required to connect with labview
title:fault detection in pen. i am doing a project in image processing using labview .i want to interface stepper motor with labview using daq how can i interface and which type of stepper motor is suitable for rolling metal sheet in which the pen is placed at the top
I would start with the motor and work down, Labview will woek with any.
1. Figure out how much motor you need: torque, speed, resolution, size (nema 23, 34 .....)
2. Select a drive for your motor: many diferent drivers to control a particular motor, How much current is required, motor voltage, inductance
3. Determine the interface to the controller: step and direction, cw/ccw, serial. (I like step and direction)
4. Determine support options for the motor, encoders, limit switches ...
5. Now you can select your ni card to match the interface, (NI Motion- good for copmlex interfaces and multimotor synchronization, Digital/ counter timers simple but limited conmplexity, less expensive but more software needs to be written)
This all depends on budget and requirements.

Running 2 stepper motors with LabVIEW using RMV ST400-NT controller and driver
Hello, I am new to programming as well as motors in general so please bare with me in my attempt to explain myself. I have a project involving laser therapy and I am attempting to control two stepper motors from Falhauber, Type AM2224-R3-AV-4.8. I will be using a RMV ST400-NT controller and driver. Original plan was to use 3 stepper motors for control in 3 axis but realized 2 axis is complicated enough. My power source is an Agilent E3630A. I am new to this whole thing and from what I have read form examples and other posts is that NI drivers seem to work best for these applications. I've written simple programs from examples, reading and watching videos. I want to know whether it's possible for these to work together using LabVIEW and also a nudge to help me get started would be much appreciated. Can someone please help guide me in the right direction, I feel a bit lost when it comes to all this. Thank you for your time and consideration. Also, I will be using Windows 8 laptop with Labview 8.5. I have attached pics of components I will be using.

I want to preface this response by saying that I am mre familiar with NI controller and driver rather than the one that you have. I am assuming that you are using the dll provided by the manufacturer here:
http://www.rmv.com/download.htm
With these, you should be able to interface with LabVIEW using the call library function node. What the controller is capable I am uncertain of. I am certain that you should be able to since another user has commented on the use in LabVIEW before in another forum post.
I also want to let you know that LabVIEW 8.5 is not supported on Windows 8, which means that you may run into some compatibility issues. Here is the compatibility chart.

Can i communicate with labview, using ethernet or seriel modbus.
Is it possible to communicate with a i/o module and labview. I can communicate with ethernet, canbus(cscan, devicenet), rs232(modbus).
What is the easiest solusion.
Is it necessary to buy PC-cards for the communication or have only to download some drivers.
ThxHello,
To communicate with a CAN/DeviceNET bus you will need an interface card in your PC. NI has such cards along with LabVIEW VIs:
http://sine.ni.com/apps/we/nioc.vp?cid=1329〈=US
http://sine.ni.com/apps/we/nioc.vp?cid=1311〈=US
To communicate with Modbus, you will NOT need any special cards but you do need software drivers for it (you'll obviously need an Ethernet card for TCP/IP and Serial port for RS232). There are several options for these drivers, however:
1. Write your own driver VIs. You'll basically implement the Modbus protocol in LabVIEW. Modbus is a simple and open protocol.
2. Try to search the Net for such existing VIs. I believe someone has already written such Modbus VIs.
3. Use the Industrial Automatio
n OPC Servers suite from NI:
http://sine.ni.com/apps/we/nioc.vp?cid=4584〈=US
4. Use any third-party OPC Server for Modbus.
NOTE: in case you opt 3 or 4 above: though you may use DataSocket in LabVIEW as an OPC Client, you may want to consider LabVIEW-DSC which has a built-in OPC Client, and hence better support for OPC.
Hope this gives you some options.

N6030A Connection with LabView
Hi,
I am working with N6030A connected to Laptop through MXI Express.
I read http://forums.ni.com/ni/board/message?board.id=270&message.id=3106&requireLogin=False
and it doesn't solve my problem, everything in IVI-drivers section on Measurement and Automatic Explorer seems to be alright
I have a code in mathlab, which can strangely communicate with the N6030A. Moreover, the N6030A Control Utility can detect the N6030A address.
However, I cannot even connect to this device with LabView.
When I use a AGN6030A driver (AGN6030A Initialize with Option) on Labview and connect it with an IVI resource name, there is only "ASRL3::INST" address available, which I don't really know what kind of device it is. Anyway, the connection using this resource name doesn't work either.
I have also tried to copy the resource name that is showed on my N6030 Control Utility, and it doesn't work.
Can you guys help me.
Thank youHi,
Which instrument driver did you download? Which hardware bus are you using (GPIB, PXI, ethernet, etc)? I assume your instrument is PXI based; is this correct?
The resource name "ASRL3::INSTR" corresponds to your serial port in your computer. If you are connecting to your N6030A using this serial port, ASRL3::INSTR is the correct resource to choose.
From searching the instrument driver network, it looks like this is the only instrument driver available. It does not look like it is an IVI driver, but instead a software utility that you can use to communicate with the instrument. How do you access this instrument through Matlab? Through a DLL? Through VISA?

Ethernet connection with Keithley 2701: Error in Initialize
Hi,
I am a beginner with Labview 2009 and am trying to interface my Keithley 2701 with an Ethernet connection. I can access the instruments internal web page and successfully use the interactive control panel so I don't think my computer is having a problem connecting to the instrument. When I run the Example VI's provided by Keithley/NI (obtained from the find instrument drivers) it works with a serial connection but when I connect with the Ethernet I get the Error: "Error -1073807343 occurred at VISA open in Keithley 27xx.lvlib: Initialize.vi". I have configured a TCPIP address through Keithley's configuration panel and the Keithley 2701 IP address shows up in the Example VI's as a port to communicate with yet fails when it tries to run the VI. If anyone has had any experience with this problem or may know how to solve it I would greatly appreciate the help.
Thanks!I have tried to list the device in MAX. However the following is given:
"VISA returned this static device when finding resources, and MAX was able to use VISA to parse the resource name. MAX was not able to successfully open a VISA session to the device."
The following post says the MAX has an issue connecting to TCPIP ports
http://digital.ni.com/public.nsf/allkb/92D475E7246846E786256ED700556D98
I am currently trying to run the VI given in the page above but as of now I keep receiving the same error message.
Thanks.
