AT-AO 10 current output question

I have an AT-AO-10 that I am using to control a few things, most of which
is using the voltage output. I am using a unipolar, external source
setting. However, I can't get my current output to work. A few
questions: Do I need to use an external voltage source, hooked up to the
EXTREF and RGROUND channels, as I have with my voltage source signals? I
know that I must supply a voltage source wired in series with the signal
that is between 7-40 Volts. But, is this my external source, or do I need
two of them. Also, the manual that came with the AT-AO-10 is pretty lousy
in regards to how to wire it. The diagram shows a 250 Ohm load
(floating). What is this? Is this something that I have to put in there,
as well? ANd wh
at does "floating" mean? If this is something that I have
to provide, does it vary with the size of my external voltage source?
I have a 15 Volt source hooked up right now, but I am also using a 24 Volt
source for some other equipment that I can use. Is there an ideal voltage
source that I should use instead?
Sorry for the ignorance. I just can't get this to work, and have very
little background in EE.
Thanks,
Harry

Do we have Digital to Analog converter with high current output?

Do we have Digital to Analog converter with high current output? I need 8 channels and each channel has at least 100mA current output.Thanks!

I have never heard of such a device. You will probably need to follow the D/A with an amplifer for each channel.
What is the voltage range and speed required? Any special protection requirements (such as current limiting)?

Generate analog current output

Hi,
I am a begineer to Labview.I would like to generate analog current output signals using a Labview card.I have been using the advantech cards till now,so have not much knowledge about which card to choose for the application.I would like to have high number (30 or more) of channels for this application. I would also like to generate pulse outputs.I have chosen the PCI-6514 to generate digital outputs,will this do for pulse output genration.It would be a great help if anyone could help me with some tips and example VIs to generate pulse outputs.
Regards
Joseph

There seems to be little reason for the user to completely replace their system with a compact RIO or something similar given they are already halfway there. They already have a card that can be used to generate their analog current output, so all they need is something to generate their pulse train.
With respect to the relays: It's usually a good idea to put something between your signal source and your unit under test in order to protect both sides, especially if the items are expensive. Are your analog current sources isolated? Perhaps that's what caused 3 of the card to burn out, but that's mere speculation on my part. However, you must be clear in your terminology since you're just confusing matters. The relays are not triggering the digital signals. The relays are simply passing the signal through or cutting it off. That's considerably different than using the relays to trigger a digital signal. Also, you would only need a relay if you needed to guarantee complete physical isolation when there is no stimulus. After all, when the relay is on, the stimulus is connected to the PLC, so you no longer have isolation. For true isolation you should look into signal conditioning products that use transformers or optoisolators, as those will give you electrical isolation. It's not clear to me if that's the case in your application.
Now, as far as the generation of the signal, as Hannah indicated the 6528 is also a static digital I/O board - you can usually tell by the price tag. While the M-series of cards provide timed digital outputs some of them require an external clock. I would second Hannah's suggestion and contact your local NI rep and explain your system in detail to them. For example, while the M-series of cards are not isolated, and if you need isolation, you may be able to use SCXI to give you the isolation. Again, I can't say for sure if you need isolation without doing a more detailed analysis of your system, and I'm not prepared to do that. One suggestion: resist the suggestion to completely replace your system unless absolutely necessary.
Good luck.

Air Output Question

I've been playing around with the free trial of RH8 and I
have some questions regarding the Air output:
1. If I add a comment, is there a way I can edit it? I tried,
but so far haven't been able to do so (I would think that I would
in case there's a typo or something).
2. Also, is there a way to show which topic a comment applies
to. Say I decide to set my comments to "Show All," is there a way
to see what topics each comment applies to?

Hi Moranis,
To answer your queries.
1. Edit is not there. Currently you can add and delete
comments.
2. You can sort the comments by topic after you do show all.
sharona27lily,
Let me answer your queries.
Comments by different users are managed on a shared network
location. End user whoever is giving comments on the AIR output
doesn't need anything else. In fact RH8 is needed for producing AIR
output. Commenting will be done without RH8.
Let me know if you have more queries.

QUICKTIME OUTPUT QUESTIONS (4 dumb ones but I don't know)

I need to output my project file as an uncompressed 4.2.2. 10 bit SD quicktime of my 89 minute edit (using that to transfer to digibeta at an outside studio). I'm on fcstudio 2.
Here is the dumbness...
As I'm going to take it to a transfer place where I notice the people working go blank if you mention color space, bit rate, up-convert issues...should I in advance include on my quicktime I bring them:
1. the 1.85 matte output on picture
this is a 4:3 sd dv sourced picture. Outputting the file is double the memory and I've had issues nesting to output in order to matte with my memory when I output..."out of memory" when memory seems to be there is an issue on the apple boards and seems to come up sometimes, sometimes not ..but I don't want to render my file TWICE in order to have a file with a matte on nor do I want someone else to render the file again with a matte on it.
2. bars and tones
How many seconds MINIMUM do I need of them anyway?
And if I'm going to BOTHER reusing this output to create an mpeg 2 file (or should I not bother and just use a quicktimes settings self contained output for the mpeg 2?) is this ANOTHER reason to NOT put on the bars and tones? Must I should just be making a bunch of different outputs?
3. a countdown with tones or click
Does final cut have choices of countdowns? I don't see it in the fcp6 effects choices am I not looking in the right place? (I'll check the manual)
4. Is there a source for film fbi warning logos without being forced to go somewhere to author a dvd because they have it? anyone have a website to get this off of?
5. Does it matter if I use the quicktime settings as is and have my settings on my project show the compressor as uncompressed 10 bit or should i just skip exporting it to quicktime settings and instead just go right to compressor?
6. If I'm going to be using another compression to transfer to mpeg2s down the road, do I need to bother including chapter markers on the output I'm using to transfer because after that goes on digibeta, the digibeta is going to be upresed to hdsr as a widescreen then downconverted back to sd as one of the formats.
Thanks

To be honoust: I do not understand all your questions.
But the main question here is I think:
How is this outside studio putting the film to Digibeta.
If they are using Final Cut Pro for that, you could setup (a copy of) your timeline as 10-bit Uncompressed. And give that to them, AS WELL AS ALL YOUR FOOTAGE. So this implies that your project needs to be well organised and all on the removable drive your going to take with you.
If not, there are other ways.
Making a 10 bit timeline and export with current settings might also help.
Or applying the matte can be done different than nesting for instance.
You can create a matte in Photoshop for instance. Or download my free letterboxer Genterator plugin at http://www.lasserij.nl/fcp or use the one of Andy Mees. It makes it possible to render parts to prevent your macjine running out of memory.
Your MPEG 2 questions are a little vague to me. As well as "film fbi warning logos". What are those?
About bars and tones. Depends on where you live and who is going to broadcast your film. Every TV station can provide you with their 'delivery-specs' (specifications). films usually start 01:00:00:00 or at 10:00:00:00 (I always forget which of them is UK and which is USA; Here in Holland we just use a starting TC of 00:02:00:00, which is very unusual in the rest of the world, I think). But you also need to consider the loudness of the Tone. Is it -12 dB, -14dB, -18dB, -20 dB? And at what level does the mix need to be done (Or is it mixed extarnally?)
In other words: Find out what you need exactly (again: delivery-specs), before starting to think about how to output.

Yamaha DTX522 e-drums output question

Hi all - I am considering buying a Yamaha DTX522 electronic drum kit to record with however i'm confusing myself with actually HOW to do it, given the outputs on the Yamaha module. I am a newbie so please bear me and correct me i'm wrong. I currently have an old Presonus firewire FireBox (they don't even make these anymore) interface, and Logic Express on a Mac Mini. I understand i can either record by using the Audio Outs (1/4") of the yamaha module, into the Firebox. Doing it this way i'd have to be happy with all the settings/sounds on the yamaha module and it would be recorded as one track. However if i wanted more control over each of the drum pads (sounds, volume, etc) and track each drum pad indivudually, i could use MIDI out from the Yamaha module, into the MIDI IN on the Firebox and track through Logic Express using some sort of drum VST. Is this correct?
My question is regarding the outputs on the Yamaha module. I see it has the regular Audio Outs, however i'm not sure what "USB TO HOST" is. I don't see MIDI OUT. Does anyone know what USB TO HOST does? I've asked suppliers and they don't really give a clear answer. My main goal is to be able to record each drum pad individually (like using MIDI out to the Firebox to Logic). Would i be able to do the same thing using this USB TO HOST output? I don't understand how i would even connect a USB cable to the Firebox if that's what I should do and if that allows individual tracking at all. Thanks!!!!

Many thanks for the reply.
Currently all pads work correctly apart from the kick and the snare. The snare for example has no audio assigned to it, if I was to transpose wouldn't the other parts of the drum kit then match up incorrectly? I also want to have the correct setup when recording, rather than just at the playback stage so I can hear exactly what is being recorded.
I'm basically looking for some step-by-step instructions that I can try in order to fix it, I used to understand logic a lot better but after not using it for years I'm back to trial and error with things.

3D HDMI output question

I'm very new to Apple iMac computers. I purchased the 27" 2013 iMac.
I also recently started using a cheap passive mini-displayport to HDMI adapter from ebay. It is connected to my 55" LG 3Dtv.
I can view 1080p60 just fine, as well as 24, 25, 30 & 50hz options using the current adapter.
I can't get any 3D options to show though.
I've read on the internet that active adapters will allow 3D output and display upto 4K @ 30hz.
What I'm confused about, is that some of the ebay listings say that active adapters are for amd eyefinity video cards only.
http://www.club-3d.com/index.php/products/reader.en/product/mini-displayport-to- hdmi-active-3d-adapter-cable.html

Any help would be greatly appreciated

You cannot use 3D with an iMac. OS X has not got drivers for 3D displays and the GPU may not handle 3D and 4K resolutions. The resolutions you see are the ones you can use

Complier output question

I've been working on a java assignment that requires me to write a command line program which will read data from a text file, store the data in a vector and then save the vector to another file in a serialized form. I have written this program using the Kawa complier software.
I have, what I believe to be, a working program; it complies without reporting any errors, but when I try to run the program, I get the following message in the complier output window.
'Exception in thread "main"'
Can someone tell me what this means?
Thanks.

Thanks for the suggestions, but I found a solution for it after posting the question. Another problem has come up now though.
As I stated, the program is supposed to read the data from a text file, store it in a vector, and output it to another file in serialized form.
The input file consists of many records of computers and peripherals. Each record uses four lines of the input file, and is displayed like this:
Description (String)
Price (float)
VAT Price (float)
Quantity (integer),
Now I think the output file is supposed to look the same as the input file, but the one my program generates doesn't. My program code is as follows:
import java.util.*;
import java.io.*;
import java.lang.*;
class TextToVector
     public static void main(String [] args) throws IOException
          try
          Vector v = new Vector(); //creates the vector
          String inFile = new String ("C:/My Documents/V3/Data/stocklist.txt ");     //Informs the program of the name, type & location of the source file
          FileOutputStream outFileStream = new FileOutputStream("C:/My Documents/V3/outfile.dat ");     //Instructs the program where to create the output file, what type of file it should be & what to name it
          //the command paths used in these lines can be modified to read/send a file from/to
          //where ever the user wants, the user must also set these identical paths in
          //the "Interpreter Options" for this to work correctly
          ObjectOutputStream objOutStream = new ObjectOutputStream(outFileStream);
          objOutStream.writeObject(v);     //writes the object to the vector
          objOutStream.flush();                     //purges the objOutStream
          outFileStream.close();                     //closes the objOutStream
          catch (IOException e)
          System.out.println("Exception Writing File ");
          System.exit(1);
public Vector readRecord(String inFile, Vector v) throws IOException
          String inString = new String(" ");
          String D = " ";
     float P = 0.0f;
     float V = 0.0f;
     int Q = 0;
          int count=0;
          BufferedReader buffReader = null;     //enures the BufferedReader is empty before beginning to read the source file
          buffReader = new BufferedReader(new FileReader (inFile));     //used to read & record each line of the source file
try
     while((inString = buffReader.readLine()) !=null)
     count++;
     if(count==1)
     inString = buffReader.readLine();
     D = inString;
     if(count==2)
     inString = buffReader.readLine();
     P = (Float.valueOf(inString)).floatValue();
     if(count==3)
     inString = buffReader.readLine();
     V = (Float.valueOf(inString)).floatValue();
          if(count==4)
     inString = buffReader.readLine();
     Q = (Integer.valueOf(inString)).intValue();
     if(count==5)
     //System.out.println("Description " + D + " Price " + P + " VATPrice " + V + " Quantity " + Q);
     StockItem record = new StockItem(D,P,V,Q);
     v.add (record);
     count=0;
buffReader.close();
return v;
catch(IOException e)
System.out.println(e.toString());
return v;
class StockItem implements Serializable
     private String D;
private float P;
private float V;
private int Q;
     StockItem()
     D = " ";
     P = 0.0f;
     V = 0.0f;
     Q = 0;
     StockItem(String Description, float Price, float VATPrice, int Quantity)
     D = Description;
     P = Price;
     V = VATPrice;
     Q = Quantity;
     public String getDescription()
return D;
public float getPriceValue()
return P;
public float getVATPriceValue()
return V;
public int getQuantityValue()
return Q;
Can anyone see anything wrong with this? I'd appreciate any suggestions. Thanks.

Tomcat output question

hi all
i think this is a simple (and quite stupid) question, but i don't know ho to solve my problem
i work on two computer (windows 2k), one where i have tomcat installed not like a service, the other with tomcat installed like a service.
when i write some servlet or jsp page i use to debug it through System.out.println() method to get the output. when i work on the 1st machine i can read the output directly by the prompt, but the problem arrives on the other machine, when no prompt is opened running tomcat.
is there a way (log file and so on) to get my application's output running under tomcat? the version is 4.1.18
thanx a lot
sandro

Hi. the solution is quite simple.
Go to your TomcatHome (where you installed it) and look for a folder called log. To check your System.out.println stuff on your tomcat as windows service just take a look to an archive called stdout.txt or something similar (can't remember the exact name)

Config output question

Is there an easy way to output the sensor configuration to a file to send to TAC? Thanks.
Shawn

You will need an ftp (or scp) server that the sensor can log into and be able to place files on.
If it is just the config you want then:
copy current-config ftp://user@server/directory/config.txt
However, the TAC usually wants a full diagnostics report (which includes the config):
show tech-support destination-url ftp://user@server/directory/techsupport.html
(The output will be downloaded as an html file)
If you don't have an ftp (or scp) server available then the other option is to run IDM. There is a diagnostics option in IDM that will bring up a similar html file as above. You can then select the File->Save As option in your web browser to save the html file and send it to the TAC.

DOM output question

Hi all,
I have the following question about writing a DOM (Document) out to a stream. But first.. a bit of background on the framework...
I have the following classes:
Listener.class -> sends InputStream to -> Parser.class
Parser.class -> sends DOM (Document) to -> Formatter.class
What I then want is the
Formatter.class -> send a stream -> Writer.class
Writer.class to do its funky stuff.
The problem I am having is trying to work out what input/output stream combination to use and what XML helpers to do it.
I am using Java 1.4 and Xerxes2 classes only...
So the question is:
1. What should the Formatter.class pass to the Writer.class?
2. What should I use to create the stream?
Ideally I want an InputStream passed to the Writer.class
Cheers,
Alex.

I don't quite follow your framework, but then I didn't try too hard because if you want to get data from a DOM into a file or some other output, you use a javax.xml.transform.Transformer. Approximately like this:Transformer t = TransformerFactory.newTransformer();
t.transform(new DOMSource(someNode), new StreamResult(someWriter));

HD to SD final output question

Hello Forum,
I have just completed Jeff Bellune’s excellent HD to SD tutorial called “hd2sd - High Quality Scaling From HD to SD”. For weeks I have been trying in vain to downscale my 1920 x1080i AVI-8bit YUV HD footage for output to PAL DVD without much luck, resulting in terrible output quality, but for anyone experiencing the same problem I would like to let you know that the quality of the conversion with Jeff's method is absolutely amazing. http://bellunevideo.com/tutlist.php Thanks for the post Jeff you are a star!
But I have one small problem. In the final process when using VirtualDub to open your AviSynth script file and then saving it out to a Lagarith AVI file.
The process works as described with great results however the final output file is exported at an output size of 720x576 - 1.250 (5:4) aspect ratio. (Size data extracted from GSpot) The problem is when I import this into Encore the footage does not fill the whole screen.
My to the forum question is does anyone know how I can change the output file size in VirtualDub to a (16.9) aspect ratio so that when imported into Encore the footage takes up the whole screen in a (16:9) widescreen format.
Can VirtualDub be used to do this and if so does anyone know the exact settings to be used?
Any assistance with this will help me greatly.
Thanks in advance.
Rex.

Thank you Jeff
You are a brilliant person, thank you very much as you solved my long standing and draining problem in one answer!
The output result is second to none as a matter of fact I can’t even tell the difference from the original footage!
Everything is fine now but while the Big man himself is about I wonder if you could possibly answer these 3 questions?
1) I am using Premiere CS5.5, Should I have used the Maximum render quality setting when exporting my MPEG2 file from premiere (this wasn’t mentioned in the CS4 tutorial)
2).My original source footage used in my test project is 1920 X1080i (1.0) 50Hz Pal - and I have exported 3 versions, one Lower field first, one upper field first and one Progressive no fields. Using the Interpret Footage techniques from your advice I created 3 separate Encore projects in each field setting the thing is I can’t tell the difference between them in my test DVDs. (Q. which field setting do you recommend me use for my final project output to Pal DVD (Note Encore Pal Project settings make reference to Lower field first).
2) Could I re-import the exported VirtualDub avi file back into premiere. Then edit my project adding effects and titles and when the project is complete export the finished project into Encore either by uncompressed AVI or MPEG2-DVD?. If this is possible will I lose much quality on export? And would you know how I could Interpret the Footage to PAL Widescreen (1.4587).in premiere? (I ask this as it would be much easier to edit with these smaller files as my original files are very resource consuming)
Again I would be most grateful if you have some advice on these questions as I am a newbie to HD editing but embracing the challenge.
Thanks again.
Rex.

How to scale current output?

Hello everyone!
I have a pressure transducer that has 4-20mA output, I'm wondering if someone could tell me how to scale current. I know I can put resistor accross the output to produce voltage but I want to do it in current.
Here's my hardwares:
Cole Parmer - Pressure Transducer
Power Input: 24vdc
Output: 4-20mA
Range: 0-100 Psi
PCI-6024E (I also have PCI-6259)
SCB-68
Thanks!

Both test works just fine. I also test the input receiving a signal out of regular power supply.
This 6259 is realy flakey to me because we have another PC that has the same daq card and when I tried the code it works.
It's just too expensive to act up like this.
Thanks for your time Sam!
samantham wrote:
Hello,
Lets try testing the 6259 by creating an analog output 5 V and wiring it into an analog input channel. Another good test will be to send a 0-5 V sine wave into an analog input to check its response. All this testing in independent of the code and configurations you are already using.
Then, I would suggest testing an analog input with your code but where the signal is coming from an analog output from the 6259 rather than the sensor. I understand your code is intended to test current. So this last test would be without the 249 ohm resistor.
Let me know if the 6259 is working with these tests.
