Encoder and S series

Do S series counters support quadrature encoders? If so, how to do connection between board and encoders?
My encoder is US digital HB6M with A,B channels, index, ground and +5VDC power.
Solved!
Go to Solution.

I am using S series NI 6123
I tried the sample code for measure an encoder. code fragment:
DAQmxErrChk (DAQmxCreateTask("",&taskHandle)); DAQmxErrChk (DAQmxCreateCIAngEncoderChan(taskHandle,"Dev1/ctr0","",DAQmx_Val_X4,0,0.0,DAQmx_Val_AHighBHigh,DAQmx_Val_Degrees,24,0.0,""));
DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandle,"/Dev1/PFI9",1000.0,DAQmx_Val_Rising,DAQmx_Val_ContSamps,1000));
But the error message is: Measurements: Selected physical channel does not support the measurement type.
Does this mean that NI 6123 doesn't support encoder meansurement?
Thank you in advance.

Encoder and E-series DAQ Board

Hello!
I am connecting a Quadrature Encoder to a PCI-MIO-16E-4 DAQ board. The board is now called a PCI-6040E. I am wondering how exactly to connect the Encoder to the DAQ board. Direction is not necessarily that important, but it would be cool if the DAQ board could tell when the direction changed. On the board are an out, gate and clock. I don't know what to put where??? Please help me???
Thank you,

Encoder and LS184 Clock Converter Problems

I am trying to implement position measurements using a 9000 CPR and 1000 CPR encoder and a clock converter chip LS184 but I have trouble obtaining a consistent count with my PCI-6035E DAQ-STC counter. The count does not seem to be correct (9000 counts in one revolution, which is times 4 in X4 mode or 36,000 counts; I am getting around 14,000 and this is not even the same every time), and the count does not return to zero when turning the encoder back to the original position. I had that problem with the direct encoder connection to the counter (A to source, and B to DIO6), and obtained the LS184 clock converter chip to fix the problem. However, it is even worse with the clock converter. I tried different values of the bias r
esistor but the problem was still there. What am I doing wrong?

Hi Ed,
The DAQ-STC counter/timer chip on your PCI-6035E card is not your most accurate counter/timer chip to perform encoder measurements. You are better off using a PCI-6601 card which is much more accurate and has real encoder capabilities.
PCI-6601 (w/ NI-TIO Counter/Timer Chip)
http://sine.ni.com/apps/we/nioc.vp?cid=3589〈=US
The reason the NI-TIO chip is better suited for encoder measurements than the DAQ-STC is because of the following (which might also explain some of the difficulties):
1) DAQ-STC can't reset the count after an encoder revolution (NI-TIO can w/ Z-Index line)
2) DAQ-STC only has one encoder measurement mode and that is the 2-pulse encoder measurement mode. The NI-TIO has the X1, X2, X4, 2-pulse
This essentially me
ans that your DAQ-STC will count up when channel A leads B and count down if channel B leads A. There is no reference point, no ability to reset and no filters on the lines to prevent glitches.
What is probably happening in your case is that you are measuring 9,000 pulses in one revolution and you are also measuring glitches on the line which is why you are getting the extra 5,000 counts. The DAQ-STC shipping example programs will give you some insight into programming your E Series counter to make encoder measurements but your errors are more likely caused by the fact that it is just a simple 2-pulse encoder (up/down encoder).
Hope that helps. Have a good day.

500GB DVR wouldn't stop resetting, now all recordings and scheduled series gone

I saw similar threads on this topic, but not sure its the same or not. On 1/11, we were watching a recorded show and it started blinking out a few times, then reset itself. It came back on and then did it again a bit later. We rebooted by unplugging it for a few seconds and it came back.
Then last night (1/12), we were watching a different recording, and the DVR reset itself. When it finished, it reset again. It continually did this around 5 times and then we unplugged it and plugged it back in. It still would just reset and reset. Unplugged again for longer. Repeat. Finally got it to stop resetting by leaving it unplugged while I ate dinner. Got it back to the place in the show we were watching, but the family had dispersed, so I turned it off. Later that night, I was watching from another STB (we have Home Media set up), and I saw the DVR said No recordings. Uh oh. I went to the DVR and turned it on and it showed No recordings and no series scheduled. I tried rebooting again a couple times and no luck. (It wasn't resetting anymore though!)
So I called customer support. I had to get to Tier III before they would agree to send me a new box. Neither knows what happened. They tried resetting remotely and re-initializing and still No recordings. They say they are sending me out a new box.
I'm not sure if we got a guide update or not. I don't remember seeing the "For HD press C", but I might have just missed it. Same with the captions options having all the options from the old system menu.
The tech guy said to call billing after we receive the new DVR to see about compensation. If it was an update that caused this and not just a hard drive issue, I am super-**bleep**. In any case, I'm also **bleep** that they don't try to physically get the recordings back. No one wants to get data off a hard drive... Fortunately I had already watched the latest Downton Abbey!

Though I don't know the size on my DVR, what you describe has been happening to me for three days now, too. Was annoying at first; now it's getting horrible, like every hour or two this happens.
A new box is coming in the mail, but still, this is looking like a more common issue than it ought to be. I'm still in my 30 day "cancel" window for FiOS TV, and I'm about ready to switch right back at this stage.

What to do?? -What to do?? - I just updated my iTunes to ver 11.2.1 because of the annoying messages they keep sending out. Now I can't play the movies and TV series I've purchased and were watchable before - This movie can be played only on displays that

What to do?? - I just updated my iTunes to ver 11.2.1 because of the annoying messages they keep sending out.
Now I can't play the movies and TV series I've purchased and were watchable before.
Comes up with "This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection)."
The cheek of the matter is everytime I tried to get Apple support it comes up with a request for me to pay $54 for their support package, to fix a problem I didn't have until I complied to one of their update requests.
End of Rant!!! - Anyone know how to fix please?

Well, I wonder about all the responses...:)
Anyhow, I wound up "fixing" the problem by using the System Restore disks for the Mini. It's now running Tiger 10.4.11 (with all updates) and I copied my iTunes library over. It all works now. <shrug> I have no idea what the problem was, and I'm a bit leery of upgrading it to Leopard, so I think I'll just leave well enough alone.

Best practice for encoding and decoding DUT/UUT registers? Class? Cluster? Strings? Bitbanging?

I am architectecting a LabVIEW system to charactarize silicon devices. I am trying to decide the best way to enqueue, encode, and decode device commands executed by my test system.
For example, a ADC or DAC device might come in both I2C and SPI flavors (same part, different interface) and have a large register map which can be represented as register names or the actual binrary value of it's address.
I would like my data structure to
*) be protocol agnostic
*) have the flexibility to program using either the memonics or hard coded addresses
*) be agnostic to the hardware which executes the command. (
*) I would like to enqueue mulitple commands in a row.
I am thinking a detailed class is my best bet, but are there are examples or best practices already established?

I agree on the detailed class inherited from a general DUT-class. Especially if you want to mix interfaces you need to keep those as far away from your top vi as possible.
As to the 4th point i'd implement command-vi's as enque and have a in-class command-queue (or possibly just an array of commands).

Exporting to Media Encoder and file locating issue

Ok, Now I've read a LOT of threads trying to find a solution to this but none of them have answered my problem exactly, so here's what I have:
Running a New computer with a clean install of Windows 7 64 bit and Adobe CS4 Master Suite
Hardware:
Dell Precision M6400
Intel(R) Core(TM)2 Duo CPU T9900 @ 3.06 Ghz, 3.07 Ghz
12.0 GB Ram
Premiere ran fine for a while, but soon I've run into a problem where I try to export to the Media Encoder and I keep getting the error:
"Could not read from the source. Please check if it has moved or been deleted" over and over
I have deleted recently imported media one at a time to try and locate what's causing it since it wasn't doing this before, but no luck. So I restarted the program but now the Premiere project won't open. The task bar loads until about 2/3 in and stops there indefinitely, I've left and came back to it 2 hours later and it hadn't moved. I back tracked and found a previous save that will open, but it still will not export, it still says "Could not read from the source. Please check if it has moved or been deleted". And as soon as I update anything and save a new file that one will not open either.
I've tried recompressing each video file into a format I know works well with Premiere but still no difference.
This problem has plagued my workflow for a while now and I can't take it anymore. I've had to restart clean project files to try to work around it but I lose so much progress, and the work around by rendering the premiere file through After effects hasn't worked either. The error I get there says "Dynamic link server is busy".
Here's what the problem is not: It is not because I uninstalled CS3 or any other previous version, I've never had it on this computer. It's not a plugin problem, I don't have any plugins on this install except for the default ones that Came with Adobe Master Suite for Premiere Pro.
Someone please help me, this is ridiculous that I have had to trouble shoot the program this much. Both CS4 and Windows 7 have been around for over a year now and neither are in Beta Editions

Wow, sorry, forgive me if I've seen most forums work with a lot less, and your dismissiveness led me to assume you hadn't read my post.
All of this is new and up do date as far as Adobe and Windows updates go, that's Version 4.2.1.
My projects for this are all in NTSC Widescreen DV 24P, the particular sequence that I render from is in that format as well, although regardless of which one I use the problem keeps occurring.
My renders for my recent purposes have been compressed in .h264, IPOD video Large. The codec I'm rendering in also doesn't seem to matter, because I've tried this in .avi., .mov, .h264, .wav, etc. and all with various settings that I thought might help, but the encoder quits encoding 4 seconds in and gives me the error that it can't find the media.
And I didn't mention the media type and what not because it seems irrelevent of what I use this problem keeps happening. I'm pretty sure it's a problem with the project file or perhaps the media encoder or both.
And I don't know what you mean by "disks"
Do I have a Raid set up on my hard disk? No, I have two 0.5 TB hard drives, Programs on one (C:\) Projects on the other (D:\).
What address am I saving the scratch disks to? I use the default of "same as Project". Have I tried Clearing it? Yes.
I don't think I'm getting at what you're asking.
And I don't think I've ever used an .xlsm (which is excel?) file and I've definitely never used a Power point project (PPS?) file in my projects. And they open in their respective programs, although I'm not sure why you asked about that. Again I'm not sure I know what you mean.
The Premiere Project (.prproj) file is what I'm trying to open when the progress bar stops at 2/3 the way through and forces me to terminate the process with the task manager to close it.
It would help to mention that all my projects are animated and I use premiere to cobble them together, so no problems that relate to transferring media from a camera to the computer would apply here. Most of the files I get out of Maya are in Default .avi or .mov files, and I also use a handful of .wav files for the dialogue and .jpgs for cards and placeholders.
I believe that this problem began when I updated a few of the files in my project, but I've been doing that for weeks without incident. I've been updating them by saving over the old media file with the updated one of the same name, length, and type.
I don't work exclusively with Premiere, in fact it's not what I usually use, that would be Final Cut Pro.

SOAP in XI: message use="encoded" and binding/@style="rpc"

Hi
Hope somebody who is familiar with XIs SOAP implementation could give the answer for my questions. Problem is that the SOAP server is not working but I am afraid that the reasons are not really simple.
In our company we have to provide some SOAP services. I have entered as much as I could in IR ... including a simple scenario. Then imported the scenario to ID and the wizard created a number of agreements and determinations...
As I need to describe the service to external parties, then I used IDs Web Service definition tool to generate the WSDL.
But as the external messaging framework (for us a preprogrammed SOAP client) is fixed, I noticed that there are some differences that might matter.
XI generated WSDL where SOAP binding has
wsdl:binding/soap:binding/@style="document" but I would need it to be "rpc"
And the second thing is that in binding message bodies have attribute @use="literal" but as the messages should have several parts then it should be "encoded" (and encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
also is needed then).
Could somebody explain if these may be the reasons why the soap server does not work. And if there is a way to define soap interface so that it would have above mentioned properties as needed.
A easy question also... I would need for a method to have an empty message... inside soap body there should be just a tag with the message name and no content. But I can not figure out how to create a message type with no datatype.
Thanks for any input!

Hi, Stefan
Thanks for the answer. To clear my questions: we want to deploy XI as the SOAP server (sry I have not figured out if it is a sender or receiver channel by name - all this inbound-outbound naming in XI is quite complex). Our SOAP server/XI is actually just one part of a big SOAP network and MAFIA it uses rpc styled SOAP messages.
The note is really useful, but still it does not give any hint how to make a RPC styled SOAP interface. So the problem is still up for me. As I am not very familiar with WSDL bindings and SOAP... for the message it self, is there any difference as for the RPC vs DOCUMENT style is discussed? Is it possible that the physical structure of a SOAP envelope could be the same?
And the second question: is there a way in IR to define several parts for a message. Something like:
<message name="isiku_andmed">
<part name="paring" type="tns:isiku_andmed_paring" />
<part name="keha" type="tns:isiku_andmed_keha" />
</message>

Continuing font encoding and tag issues with snow leopard and CS4oI

I am looking for help with a font handling issue with snow leopard and cs4 Indesign. Despite numerous calls and hours on the phone neither Apple nor Adobe has been helpful. I have had this issue open with Adobe since oct 5 but they remain totally unresponsive to date. I need to be able to use Type 1 fonts and do the following , export a pdf from Indesign with the following attributes: 1) xml tags for stories and objects. 2) have the fonts encoded as ansi and embedded.
Some additional information - exporting to ps is not an option as it destroys the xml tags. and doesn't guarantee that the fonts won't become CID or some other odd encoding.
As it stands now,
Leopard (10.5.8) and CS3 creates ansi encoded fonts with xml tags.
Leopard (10.5.8) and CS4 creates ansi encoded fonts with xml tags.
Snow leopard and CS3 creates ansi encoded fonts and xml tags
Snow leopard and CS4 creates custom subsetted fonts and some xml tags.
If any one has any advice on how to force specific font encodings from CS4 pdf exports so that i can preserve the tags and get the correct fonts I would be grateful.

The font encoding is not a function of the OS version, but rather of how a font is internally encoded and the content you are representing with the font.
If you are seeing a difference between MacOS 10.5 and 10.6 with the same Adobe software, it probably has something to do with use of a system font that is somehow different from one version of the OS to another. InDesign does not use any of the OS' font handling software.
Assuming that the fonts are embedded, subset or not, what is your issue with whether a font is ANSI-encoded, custom-encoded, or CID-encoded? It should make no difference for purposes of workflow beyond InDesign for software that adheres to the PDF specification (including all versions of PDF from 1.3 and up to 1.7 plus ISO 32000-1 PDF and all versions of PDF/X and PDF/A).
Neither InDesign or any other Adobe application provides user choices for the encoding since it shouldn't make a difference. The encodings chosen by Adobe's core technology components are for a combination of optimization and to support proper text search, copy, etc.

Encoder and analog feedback together

I am using a PCI 7344 board that will operate up to 4 axis with both encoder and transducer feedback.
The user will have the ability to switch between the two types of feedback whilst on the fly with the system momentarily executing a stop command before re-configuring itself in the other mode be it encoder or transducer. This works fine.
My problem is - when I am in encoder feedback mode, I do not get a feedback reading from my transducer as my primary feedback device is the encoder and as such the output given is for the primary device. I need to be able to see the analog feedback device whilst operating with the encoder and primary feedback.
I may have a solution to this, by using one of the feedbacks as the secondary feedb
ack although could not find any information regarding secondary feedback on NI's web site.

Hello,
First of all, analog feedback can not be used as secondary feedback. When you are running on analog signal as your primary feedback, you should be able read encoder data calling the Read Encoder Position.flx. When you are running on encoder as your primary feedback, you should be able read analog data calling the Read ADC.flx. If you do the enabling/disabling properly when you are switching from one feedback mode to other, you should be able to read all the signals.
Hope this helps!

Can anybody help me with this. Actually i need to study the performance of jpeg2000 compression using different setting of parameters.
Thanks in advance.......

Hi,
I am able to encode and decode the image using J2Kwriter and J2Kreader classes. But now some other issue has came up.
When compressed losslessly, the new jpeg2000 filesize is 415245 bytes. (My original file is of size 2000000 bytes)
But when i am doing lossy compression, it results in following file sizes.
Below 0.5 (encoding rate) - 535 bytes.
Greater than or equal to 0.5 - 541 bytes.
I tried with the following values of encoding rate - 0.1, 0.3, 0.5, 0.8, 1, 1000, 100000000, 500000000.
I m not able to understand why i am getting the same filesize even with different encoding rate.
How should i set the encoding rate parameter to achieve my target compression ratio.
Kindly guide me. I will be very thankful to you.

Which type of ADC is used in M Series, S Series and C Series DAQ Cards?

Hi
I want to know which type of Analog to digital converters(ADC) are used in M Series and S Series DAQ Cards. I know that DSA Cards and some C series are using Delta Sigma ADC. What about the ADC used in non delta sigma C Series modules. Why Delta sigma ADC is not used in M series and S series DAQ cards.
Regards
Samuel J

Hi Samuel.
The ADC type used is Succesive Approximation ADC. You can refer to the following links for your reference.

1600 and 2600 series aps no heatmap on cisco prime 1.4.0.45

after plotting 1600 series and 2600 series aps on the respective uploaded maps, there's NO heatmap coming out.
setup composed of:
1600 series aps
2600 series aps
wlc running HA (7.4.121.0)
cisco prime 1.4.0.45
i noticed some errors from prime:
error 1: Exception while computing Coverage Heatmap. Message: COMMON-1 Try Recompute RF Prediction - this error message shows after positioning the aps on the map and clicking save button. it took sometime to display then this error message shows.
error 2: Error in Recompute RF Prediction: SyntaxError:syntax error - this error shows after running recompute rf prediction option
i tried 802.11a/n and 802.11b/g/n protocols but still no heatmap. i tried unselecting ap heatmaps option and select it again but still no heatmap.
anybody have an idea what is going on? tia

Hi,
Try removing both APs from the map and saving. Next, go back into the map an assign the APs. If they still do not map then I would look at the traps on the controller and make sure that the AP is fine. I would also look at performing an on demand refresh from the controller to the WCS. You can do this from the management page in WCS.
