1473R DMA timeout at high speed?

I'm using a 1473R with a Basler line camera spl2048-140km. I managed to modify the example to run the camera on both 8 tap 8 bit mode and 4 tap 12bit mode. Both run well at low speed. However, there are two issues when I try to run it at high speed.
If I set the frame trigger at relatively high speed before I start the acquiring (like 30kHz), a DMA timeout error will jump out as soon as I start it (error -8999). If I set it at low speed (like 100Hz), it will run fine as I increase it to 30kHz after it starts.
Another issue is, when I try to push the speed of the camera to its limit, which is 70kHz for single channel mode and 140kHz for dual channel mode, I will always have the error -8999. It happens when the speed reaches 100kHz in 8 tap 8 bit mode, and 50kHz at 4 tap 12 bit mode. I wonder where the bottle neck is and if there will be a way to solve it.
Thanks!

I'm not that familiar with the FPGA code for the 1473R, but I am fairly sure that the DRAM example has been tested with fairy fast cameras. That said, it seems from looking at it that it does not have a good feedback mechanism if PCIe bandwidth is not available. It's only feedback seems to be if the host DMA buffer fills up (e.g. host code doesn't read it fast enough). Since PCIe/memory bandwidth is extremely host-dependent, it is quite possible this example is not well tested with the combination of very fast cameras and some systems that have more jittery PCIe bandwidth. I'm not sure of the specifics of the DMA FIFO behavior, but my assumption is that the number of elements remaining really only concerns itself with host space available. For most situations, the minimal amount of FIFO built into the DMA engine likely makes this work fine.
First, I'd try instrumenting the code to figure out which specific part in the FPGA code is timing out. The example doesnt seem to track all the error cases well.
Assuming it is the host DMA that times out AND it always reports that there is free space available, my suggestion would be to modify the code to let the DMA step retry with the same data the next clock cycle on a Timeout and let the data back-up in DRAM as needed.

Timeout errors when using high speed camera.

Hi all.
I'm currently trying to capture images using a Mikrotron EoSens MC1363 camera at high frame rates >500fps. The issue arises when the region of interest (ROI) is decreased in the microtron software (of which screenshots are attached). The ROI must be dropped in order to increase the fps. When MAX is opened and configured to match the camera settings, and grab is initiated, the timeout error occurs. I've attached screenshots of the mikrotron software, max settings, the error and PC used. The OS is windows 7 64 bit. We use the camera config file for the mono version of the camera which i've been informed will cross over to satisfy the colour version we use. Any questions feel free to ask. Thanks.

Hi Dom.
As you said the maximum frame rate with the ROI set to 1280 x 1024 is 505fps but according to the general information for the camera series:
The Mikrotron EoSens camera series features extremely sensitive high-speed
CMOS sensors available in monochrome or in colour with a resolution of 1280 x
1024 pixels and capture rates of 110 or 500 frames per second. Depending on
the model the image data is transferred in 8 or 10 bits via either CameraLink
(Base, Medium or Full) or Gigabit Ethernet.The region of interest (ROI) can be
freely selected, and the cameras can achieve even higher capture rates up to
120,000 fps when the ROI is reduced
Therefore it was my thought that by reducing the width of the ROI increased frame rates may be reached. Realistically we're looking for as high frame rates as possible so that the camera has capability to pass between projects. Currently the moving object enters and leaves the ROI within a 4 frame window, so frame rates of up to 1000fps would generate more data. Naturally, a point will come where the data cannot be physically written as fast as it is generated (>600MBps). Therefore it would be useful to get a handle onto why the error occurs as well as methods to fix it. Hopefully the problem is being discussed between NI and Mikrotron and we may have some answers in the near future.

I'm having the same problem. My scanner is a HP ScanJet 8250. I'm using Adobe Pro Extended & Windows Fax & Scan programs. Currently running Windows 7 (64 bit) Professional on an Intel i7-2600 CPU with 4x2.00GB of DDR3-1333 RAM
When using the feeder tray, it will either feed 3/4 of a page before timing out or it will not scan anything at all. When using the flatbed, the scanning bulb will move down the glass but then stop at the end and timeout.
I did have this scanner fuctioning properly on another computer using Windows 7 (64 bit) Ultimate but the hardware specs elude me at this point in time. I saw there was a firmware update for previous generations of Windows but nothing for Windows 7.
So far I have tried uninstalling & reinstalling the driver. Switching through every USB port on the tower. And I've swapped out the USB cable.
Any help would be greatly appreciated.

Onboard Wait On High Speed Capture

I would like for an onboard program to wait for a high speed capture signal from a trigger input. Unfortunately, I have not had success with the flex_wait_on_condition function; it has always timed out before detecting the event. However, calls to the function flex_read_hs_cap_status identify that the high speed capture line is indeed toggling faster than the 3 second timeout. I use the following sequence of functions to configure the high speed capture:
flex_configure_hs_capture(m_BoardID, NIMC_AXIS2, NIMC_HS_LOW_TO_HIGH_EDGE, 0);
flex_begin_store(m_BoardID, ProgramNumber);
flex_enable_hs_capture(m_BoardID, NIMC_AXIS2, NIMC_TRUE);
flex_wait_on_condition(m_BoardID, NIMC_AXIS2, NIMC_WAIT, NIMC_CONDITION_HIGH_SPEED_CAPTURE, 0, 0,
NIMC_MATCH_ANY, 30, 0);
flex_end_store(m_BoardID, ProgramNumber);
Axis 2 is configured as a open loop stepper axis with encoder resource 2 mapped to it.
Any thoughts as to why this wouldn't work?
Thanks!

Thanks for the suggestion. It seems to work fairly well, although there is some delay between the trigger event and the execution of the critical section of code.
Are you aware of a method to speed up execution of an on-board program? The critical section of code in the attached program fragment takes about 4ms to execute. With the added delay of the polled high speed capture line, I am limited to a ~150 Hz loop. I would like to increase the execution time by about twice.
Also, a command from the host computer seems to preempt the on-board program, causing it to take up to ten times as long to complete. Is there a way to set the priority of the on-board program task above host communication?
Thanks for you assistance,
Mike

Mapping the High Speed Capture signal to RTSI

Hello,
Can i Mapp the "High Speed Capture" signal to RTSI ?
When i'm using the motion RTSI example and mae some changes:
i'm setting the source to "High speed capture" and the destination to RTSI_0 i 'm getting an error that its possible!
i want to use this input to trigger an action on other pci.
I'm using pci-7344 with umi - 7774 and pcie-1430

Dear Jochen,
Thank you for your reply.
I try to map the High Speed capture to RTSI , but the HSC doesnt work.
When i remove the RTSI mapping from my diagram, the HSC work and i can capture the encoder position.
I'm using the UM7774, and the HSC is wired to the global connectors (TRIGGER/BREAKPOINT connector)
I also read all the relevant documentation about my hardware and i notice that there is a comment about mapping the motion rtsi :
(from Select Signal vi Help): Note You must route signals from the RTSI lines before you enable high-speed capture ,
so i also consider that, it still doesnt work....
I really appreciate if you can take a look about the 2 versions of vi i attached here.
They both need to do the same.
Each vi contains 2 parallel diagrams, one diagram for the single axis move, the move is to target position X,
the second diagram is for the vision, there is "trigger each line" from rtsi line (the motion diagram includes maping the encoder phase A to the rtsi for this purpose)
and i want to use the High speed capture to trigger the start of imaq also.
The example :
HSC in motion activate the start of imaq in second loop.vi
is a working example that runs good and capture the image.
but its "dirty" programming, i dont think its should work like this.
its actualy a implementation of "busy wait" loop.... ( i dont like it, but work...)
The example :
HSC triger directly the start of imaq.vi
is hoe i think its should be ( i know that i need to trigger the HSC whitin the time of the timeout of waiting to the start trigger of imaq to accure, that is why i put a big number there... )
BUT, this vi doesnt work, the High speed capture doesnt happend at all...
Can you take a look on these vi and let me know what i'm doing wrong here.
I really appriciate your help.
Regards
Mor

LabVIEW does what the diagram tells it to. If you are calling a single point
Analog read function in a loop, it is software timed and the overhead
for this
type of acquisition is pretty high. If you configure the card to trigger
when it sees the edge and tell it how many post-trigger points to return,
then the DAQ will be hardware timed and is limited by the clock on the
board and the configurability of its various counters and ADCs. Look at
some examples that do triggering and HW timing.
LV doesn't write anything to disk unless you tell it to with a write icon.
The values you collect can be collected in an array and written to disk when
there is computer time to do so. If you don't have much memory in your
computer, the OS may be using virtual memory without LV even knowing
about
it.

How to write to DAQCard-5633 Port at high speed

I am looking for a sample vi that allows me to write a 8 bit x n digital array out at high speeds with a DAQCard-5633 high speed digital I/O card. I realize I need to use the traditional DIO vis, specifically the DIO Write.vi, but haven't been able to make it work yet. I tried the sample vi I found on-line called syncDIO_32HS.vi, but that doesn't write anything out, and gives a timeout error. I know the card works because I can do low speed DC write type operations.

I found the solution myself. If I am using I/O connector handshaking I need to connect REQ and ACK. I should have used internal handshaking.

Buffered high speed capture

Hello,
I am looking for any example of an on-board buffered High Speed (HS) capture. The only example I've found so far (see http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3D77D56A4E034080020E74861&p_node=DZ52480&p_source=External) deals with single HS capture mode and cannot work with the high frequency capture of about 1000 Hz that I am interested in. Can anybody help me?
Thanks.

In this case NI can offer you two solutions:
1. NI offers hardware upgrades. You could contact your local NI branch and ask them to exchange your 7344 with a 7354 (or a 7352 if you don't need more than two axes). This would be the best and easiest solution but maybe not the cheapest. At least you could ask them to send you a quote. Please take into account that the connector of the 7354 is compatible to the connector of the 7344 so you wouldn't have to buy additional cables or connector blocks.
2. You could add a PCI-6601 counter board to your setup. The 6601 can be used to measure positions by either connecting the encoder of your motor to the inputs of the 6601 (in parallel to the 7344) or if you don't use an encoder (open loop stepper) then you could measure the step/dir signal of the 7344 with the 6601. You can connect your trigger signal to the 6601 for a buffered position measurement. The 6601 supports DMA so a position measurement rate of 1 kHz is absolutely no problem.
The disadvantage of this solution is obviously the additional cabling and a higher complexity in programming.

I owned an Apple Tv and since I upgrade my internet to higher speed my Apple Tv does not work. Please someone help.

In most scenarios you shouldn't need to forward ports, however if you need to, you may be best contacting your ISP.
As with most router issues, I would recommend that you contact your ISP with details of your problem (assuming that it was your ISP that provided it to you).
There are simply too many manufacturers with different software features and settings and often different names for such features and settings, that the best advice will likely come from those that are knowledgeable about your particular router.

How can a session be setup between two MacBook Pro's at different locations on high speed Internet connections, be setup to have a live recording session in Logic?

My partner and I live on opposite sides of the valley here in Phoenix. About 50 miles apart one way. We are Musicians and are working on a commercial for television, and would like to know if there is a way, between FaceTime and Logic, that we can configure our MacBook Pro's to record sessions together without having to be at the same house? When we FaceTime, he can hear my keyboard through his headphones, but we can't seem to get the signal routed into Logic and register to a track when its record enabled. Is there a way for us to save gas, and record at seperate locations, so he can engineer me and I can engineer him, while we build this project in Logic and Final Cut? Here is what we are using, we have nearly identicle setups, which was planned so we might be able to do something like this. Both of us are using Mid 2012 15" MacBook Pro's with 2.6GHz Intel i7 processors and 16GB RAM. The only difference between the two MacBooks is that his has an Optical Drive, but I removed mine and replaced it with a 2nd SSD Drive, so I have two Samsung 840 Pro's each with 512GB in my MacBook Pro. His just has one Samsung 840 Pro with 512GB. We both use Focusrite Saffire Liquid 56 Firewire Audio Interfaces, and we both use Logic Studio 9 Academic. I don't know if you need to know what we are using in order to help us figure out how to configure the MacBooks for a live session, so I figured I would give you those details just in case. If you need any more information, just let me know? Oh, we both have high speed cable Internet connections. Mine is 150Mbps speed which is the absolute fastest I can get in my area. And his is only a 50Mbps speed line.
Again, what we are looking to do is have a LIVE recording session, in Logic, with him at his house and me at my house. When we FaceTime each other, we can pretty much hear each others keyboards as if they were part of the conversation, and as crystal clear as we can hear our own when recording, but we can't seem to record enable an Audio track in Logic and route that keyboard signal into Logic and record it so we can engineer each other without either one of us having to drive to the others house, to be there to do it. If any of this even makes sense, I'm not quite sure how to better explain it. So hopefully you get what I mean, otherwise just say so, and I will try to do a better job explaining it. :-)
Anyone who can help us with this little problem would be greatly appreciated, and quite a hero in these two humble Musicians Worlds!! So from both of us, THANK YOU in advance for any input you might be able to give us. I look forward to hearing any and all suggestions.
Scott

Hey Scott
You and ALOT of people are attempting to do this, myself included.
Unfortunately at this point (to my knowledge) it's a pretty CRAP setup involved that will likely leave you frustrated.
HOWEVER:
A few things CAN be done:
IF you are getting live audio from your partner over the internet, you can re-direct that audio directly into Logic using a program called SoundFlower.
There are a few alternatives to SoundFlower, like JackTrip, and.....(the name eludes me)
(SoundFlower is from a company called Cyling 74 who also makes Max MSP. )
Once in Logic, you set your audio inputs to the track to be Soundflower. (either 16 inputs, or in this case 2)
That all being said, regardless to speed, you are still going to experience latency in the connection, and THAT is the part that will likely drive you to the mad house.
THIS all being said, I believe there are websites out there that are set up to actually do this kind of thing, (at least there WERE) but likely membership costs, and other "hidden" problems that you only learn about after you have signed on the dotted line. (Hopefully I am wrong?)
If you don't need to do a "live jam", there are always solutions like DropBox that work very well for exchanging large files quickly.
If you want to record live MIDI input from his keyboard, I am unaware of any solutions for this.
Due to the popularity of the iPad, you might want to look into the App store, and see if there is something available.
Good luck!

How can I stop spam from someone called AT&T High Speed Internet? I do not know what the email address is.

I am receiving 100's of spam emails. They are all advertising different types of products but they all say they are from AT&T High Speed Internet. I have used the junk filter on them but it does not pick them up as junk. I have to do it manually each time. I have contacted my UVerse provider and they cannot assist because it is getting through Yahoo to Thunderbird. They say that it is a problem that I will have to have assistance from Thunderbird to resolve so that I can have this listed as junk and will not have to do this manually. I am at my wit's end. Please, please help me!

Yahoo has its own junk mail filter (Spamguard), which you should confirm is enabled:
* [https://help.yahoo.com/kb/mail/stop-spam-yahoo-mail-sln3227.html Mail Help | - SLN3227 - Stop spam in Yahoo Mail]
The significance of this is that marking messages as junk in Thunderbird probably isn't integrated with Yahoo's system, so Yahoo may not be getting trained to block them. You might need to go into Yahoo from time to time and mark accumulated junk as spam.
Separately, there are solutions for filtering spam on your computer as the mail is downloaded from Yahoo. Thunderbird has a built-in filter, as described here: [[Thunderbird and Junk / Spam Messages]]. However, if that isn't as effective you would like, there are third party products as well.

How do I use the High Speed Data Logger with multiple I/O devices?

I am using the High Speed Data Logger vi to read from a 16 channel A/D card (NI PCI-MIO-16E). The project may require more than 16 channels. How can I use High Speed Data Logger to read from two A/D cards? Will it be able to write the data to one file?

The High Speed Data Logger vi will not acquire and right to multiple DAQ boards at the same time without modification. LabVIEW is more than capable of doing this what you are trying to do, but you will have to modify the code.

Hello all.
I have just set up a new cisco DPQ3925 wireless router that Optus sent me to be able to access the higher speed internet I have signed up for.
I have a 4th gen apple extreme that I want to use to extend the wifi but when I try to update the settings via the airport utility I get a message that says it cannot do so, and to check it is in range and the wifi is set up correctly. I'm not experienced with these things but I can't think what I have done wrong.
Is anybody able to help me please.

You cannot use the AE to extend wireless from a non apple router such as your cisco modem router.. they are not compatible..
You need to tie to the two devices together either with ethernet or something like EOP adapters.. They are about $120 and you can price match in officeworks.

How can I set up a home wireless network with Comcast high speed internet?

I just signed up for Comcast High Speed Internet. I was able to get my Power Mac onto the internet. However, I connected my Airport Extreme and am unable to get it to recognize that I have an internet connection. I want to set up a wireless network in my apartment. Comcast tech support said that I only have one IP address.
Any suggestions as to how I can get my wireless network up and going? Thanks!

Should I change set up so that cable goes from the cable modem directly to Airport Extreme and then use the ports on the Extreme to run Ethernet Cable to Power Mac and other devices?
Yes
As an aside, would this setup allow me to hook my iBook up to Airport via Ethernet cable and let it get into Internet that way?
Yes
