How to send power-on signal over tty-a instead of keyboard

I have an u-10 running without keyboard and without screen; but only connected through a serial line on tty-a port.
I can shutdown on poweroff via 'init 5'.
But how can I get the maschine power-on with going to the maschine and pressing the power buttom.
Can I send power-on via tty-a ?

It is not possible.
The hardware design of U-5/U-10 systems is simply as a desktop system, not a server.
(They share the same systemboards so they are the same system design.)
Once you've brought your Ultra-10 to a power-off state, it's an inert lump of equipment.
The front power button needs to be pressed to latch the power to an "on" state.
This is the same as for any off-the-shelf PC design from Dell, Gateway, Compaq, etc, for the same 1997 time frame. (that is when the U5's and U10's were being developed)
You could possibly choose to bring the system down to run level 0 instead, leaving it at OBP.
You would not save any electrical costs, but at least the OS wouldn't be active.

How to send a modulate signal by the NI PXI-5441?

How to send a modulate signal by the NI PXI-5441?
I am using NI PXI-8108 / PXI-5441.
I want to send a binary signal modulated (FSK) by the 5441. I tried to use, without success, the modulation VIs with the Fgen VI.
Thanks

Hi Mauro,
the code structure is similar to any structure of I/O. You need open the communication channel with the hardware (using VI Open), use VI Write/Read to send/receive data and close the reference (VI Close). You can look the structure in LV examples.
Nevertheless, if you cannot, post your code that I analize to you.

How to send a ttl signal with a good exactitude less than 10ms?

i have a pci 6013 (8 input channel) and pci 6711 (4 outpout channel).Then i need to send a ttl signal to a camera ccd to take a photo when a waveform sinus is equal at zero (rising), but when i send this TTl signal with dasylab using generator pulse or combi trigger and readind this signal, i have difference between dasylab pulse(that is exactly) and measurement pulse that is approximate 40ms after.But i need to have less than 10ms is it possible?
Frequence rate =1000hz and block size=512 the waveform sinus is 0.2Hz.i have already try to increase the sampling rate but nothing happens.Thank for your help.

Yes, it's possible.
You just have to reduce your block size to 10 !

How to send a text file over a LAN?

Hi:
I am working on a program (web app using a servlet), that produces a text file with Key / Value pairs ex) NAME
joe
CITY
los angeles
I want to send the text file over an intranet (LAN) to another pc and store it in the C:\temp directory of the receiving computer.
Is it best to use the Networking package? Any idea on tutorials or code samples to help assist me? (I posted on Servlet Technology forum; nobody answered though...thanks for any thoughts.

one way cud be that u write a program to open a port on the computer u want to store and make that program save on the required directory. then u can send a simple file in byte format over it. but doing this only wud b unsafe as others wud also hav the access. wat u cud do to prevent is to put some kind of password so that first u authenticate to server b4 u pass on the file.

How to view change in signal over specified time

I'm trying to create a .vi that will view an incoming signal (temperature or pressure, in this case), compare it to data over a specified amount of time, find the delta, and if it fits into a set range, output a true boolean.
In real terms, I want to view a temperature over, say, the last five minutes, and if the delta is less than two degrees, light up a boolean.
I know I'll need the elapsed time module, with a control multiplied by sixty for the "time target", and the "time has elapsed" as the boolean control. I'm assuming it will also look at a comparison between the present values and the values stored in an array and if it's outside the specified delta it will output a true value to the "reset". This will also have to reset the array, is my assumption.
I'm new to programming in general, and LabVIEW, so that's about as far as I got in the logic before I decided to see what the forums have to offer.
Thanks,
-Ian

Is this steps in the right direction? Seems like it should work, anyone see any flaws here?

I am sampling a signal at 1kHz for every 1 second. How do i average the signal for N seconds?

I am sampling a signal at 1kHz for 1 second. After one second of pause, i sample again for 1 second at 1kHz. If i do this for Nth time, how do i average the signal over the 1 second period?

Anyway you need to have the data to compute the average... and usually you don't get the data point-by-point unless it is very low frequency acquisition.
If it is the case, you have to update your 2D vector point by point and then compute the average after each new point (much slower process indeed). You keep say 20 vectors of data and fill in the data (1, 2...20) and then( 1,2..20), so you compute the average on the last 20 acquisitions

How to send as iMessage instead of text?

I just got the iphone 5c and i was trying to figure out how to send a text as an imessage (blue) instead of a sms (green). When i start a conversation with contacts that i KNOW have imessage turned on, it always sends as a text! How can I fix this? I dont want to completely stop sms with other non iphone users, but i want to be able to send imessages to iphone users.

Yes, i can send an imessage, but i cant start a conversation in imessage, the send is always green then after a few texts it starts sending imessages
Both you and the person your messaging has to have an active data connection.

How to send a SQUARE WAVE to PXI-6259 over the LAN

howcan I send a SQUARE WAVE to PXI-6259 over the LAN, is
there any example or link any one can send me , thanx in advance.

Dear HaI L,
I managed to send a test signal (sine wave) to the device by choosing
the test panel option and choosing Analog output. In the analog output
I could many channels to choose from. ai0, ai1.ai2 and ai3.
I did this by right clicking NI PXI-6259, in the NI DAQmx devices
located in the Devices and Interfaces and choosing test and saw it on
an Oscilloscope without using the NI DAQ OPC capabilities, and I cannot
understand this thing.
1)How can it be possible without making a NI DAQmx channel and Variable?
2) I cannot create any channels in the devices and interfaces located
in My system but I can create NI DAQmx Global Virtual channels easily
in Data neighbourhood in the remote system, Plz tell me why?
3) I want to create a program and choose a channel to send the
signal, can I choose the channel that i create in the remote
system device ? and if yes how can I choose this ?
Thanx in advance.
Sincerely,
Munir Afzal Bhatti.

How to send joystick data over TCP connection

Hi all,
I am a long time Labview discussion forum user for learning, but this is my first time posting a question, I hope somebody can help me!
In the attached VI I am trying to send data from a joystick over a TCP connection. I can send data fine using the TCP examples (in fact the majority of my VI is just a copy of the example). However I am to the point where I do not know how to send all the data necessary (3 axis data, 12 buttons, and the POV data) over TCP. Strings, clusters, and arrays were never my strong suite and converting between them is a nightmare for me.
Basically I am trying to send each axis data (X,Y, and Z), button data (12 buttons), and POV data (the POV data will be calculated to adjust the position of a camera, so the immediate data is not important, I will add functions to add the change in the button movements to write a standing position for two servos [pan and tilt], for which that I will need to send over the TCP connection) over the TCP connection to control various cameras and motors. I don't know if it is posible to send that much data over a TCP connection in one write VI through a string, and also how to separate the string on the other side in order to control the client VI.
Again, the actual TCP communication I get, and can operate fine, just formatting all the data into a string (or whatever is required) so that I can unpack on the other side is the issue here.
Another question I have (not impotant to get the program running just might make it easier on me) is can a TCP server (which sends the data to the client) also recieve data back from the client on the same port ( for example sensor data and digital positions [on,off])? Or do I need to set up two TCP communication loops with the first client acting as the server on a different port than the first, which then sends the data to the original server, which also has a client TCP configuration in another loop? I hope this makes sense...
One final question.....I already have a solution to this but using labview for the entirety of this project would be nice. I use skype to stream 1080p video from a webcam to my computer so I can view live feed. Can labview do this? This would be awesome if so, I am just not sure if the communication protocols in use could support real time (or as close as possible to streaming) for 1080p video.
Thanks all in advance for your help,

Well, you cast the axis info cluster to a string, but then you cast it back to an array of DBL. Thatr's not compatible. You should probably cast it back to an "axis info" cluster of exactly the same type. Go the the other VI and right-click the cluster wire to create a constant. Now move that diagram cluster constant to the other VI and use it as type.
Your default ports don't seem to match. You seem to have client and server roles confused. In the sever you create a listener, but then you start sending packets, even though no connection is established. The connection needs to be initiated by the client.
Your client stops the loop the first time a timeout is encountered. Shouldn't that be more permanent? Also, please retain code clarity and avoid unecessary complexities. For example, replace the "not or" with a plain "or" and change the loop to "stop if true"

You can send as much as you want. The casting to/from string is the same as described above.

The primary function of a "server" is to wait for a connection and then communicate with the client once a conenction is established. An established TCP/IP connection is fully two-way and both sides can send and receive.

how to edit xml file particular value. and how to send xml file over ip address 192.168.2.10 device using ftp through Ethernet

Hello
For using FTP function in LabVIEW, I recommend you to check this document: FTP Basics
Also, take a look at FTP Browser.vi, which is available at the Example Finder.
To edit a XML file, try to use VIs in XML palette. Maybe Write to XML.vi helps you.
Post your current VI if possible.
