Route scan clock to high speed capture

Hi, I want to have a continuous aquisition and sample into an array two encoders and my e series channel about 100 scans per sec. I will be routing the board clock over RTSI, assumed to bt the gerneral purpose clock, to do a high speed capture from two encoders. Absolute positions and AI must be syncronized. Can I use the internal clock from the e series, and what is it called? How do I get a periodic sample from AI to be stored with each high speed capture?

Matt,
To synchronize your analog input and encoder measurements, you will need to route your analog input scan clock over RTSI. In LabVIEW, you will use Route Signal.vi with AI scan start as the signal source input and your chosen RTSI line as the signal name input. This RTSI line can then be used to latch your encoder readings into a buffer. Thus, the data in your analog input and encoder buffers will be synchronized.
Good luck with your application.

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

Buffered high-speed capture with multiple axes

Has anyone succeeded in using buffered high-speed capture (on 7350 boards) with multiple axes?
The capture works really well for me on a single axis, but when I try to use it on 2 axes simultaneously it behaves very strangely. There seems to be some kind of unwanted interaction between the two buffers which means data points are lost and they often stop updating altogether.
A very similar question was posted here over a year ago (http://forums.ni.com/ni/board/message?board.id=240&thread.id=4087), which includes a more detailed explanation and an example VI. Can anyone help? I'm using LabVIEW 8.5 RT with NI-Motion 7.6 and a 7358 board.
Thank you,

Hi Ian
I have been asked working with kostas on this problem for you and just wanted to give you an update as I know its been a while and is an important issue for you. I have been chasing up our specialists in the field and resently had responses of the kind:
"Hi Graham
The issue was found out to be a bug in our motion driver. The issue is being examined by motion R&D right now. I do not know a time frame on when this will be fixed as it is proving to be a tricky problem. I am copying Stuart and Lorne on this since they have been working on it as well.
Thanks,"
Be assured that I am chasing it as closely as I can. From your end what is the situation, do you have a work arround that will suffice or are you still waiting on this.
Thanks for your understanding and I look forward to hearing from you with your current situation.

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

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.

Router settings to accomodate high speed software

Hi,
I'm using a WRT300N. I can't figure out how to configure it for the requirements of my trading software. Here's what the software vendor says
If you are in an office, your network's or ISP's firewall must be configured to allow outbound TCP connections on ports 80, 443, and 1838 for all IP ranges listed below (regardless of location). It is not necessary to configure these ports for inbound connections from our servers.
Chicago IPs:
63.75.60.*
63.75.61.*
63.75.62.*
63.215.120.*
198.207.140.*
New York IPs:
63.160.212.*
63.160.213.*
I can't figure out how to match the WRT300N settings to these requirements. Help!
Thanks,
Hal

It clearly says "It is not necessary to configure these ports for inbound connections from our servers." You don't have to do anything. By default all outgoing connections are allowed on your WRT350N unless you configure access restrictions on the router.
Thus, if anything is blocked it is your ISP.

Buffer high speed capture

when i use the Vi shown in figure uploaded ,the captured positions can read from the buffer either the the trigger is input or not.Is there anthing else to configure ?

This is the Final Cut Express forum, and no there aren't any tape deck that will do that.

Continuous, triggered, high-speed motion capture

Hello,
I'm attempting to perform a continuous triggered high speed motion capture independent of the motion, and it's not clear that this is possible. Before I spend a few hours on a wild goose chase, I thought I'd ask around.
I have a digital pulse train coming in at about 100 Hz and I'd like to measure the position of my motion system in all 3 axes at each pulse. Having acquired the data, it should then get dumped to a file. This should happend continuously until the user exits the program. The continuous part of this seems unnecessarily complicated, involving on-board programming, if my reading of examples such as onboard-hsi-gpbuffer.vi and continuous_hsc.vi is correct. However, if that's the worst of it, I'll survive.
Meanwhile, the system is undergoing random motion, including starting and stopping of the axes. This is the part that has me particularly concerned. All of the examples that I have seen, both bundled and otherwise, seem to include a single move as part of the program. Since my system will be undergoing multiple moves controlled by the user, I'm concerned that these moves (or the end of the moves) will cancel the capture operations.
Does anyone have any insight into this sort of setup?
Thanks,
Jason

This seems to do the trick. It's based on the "Onboard Program - Continuous High Speed Capture into General Purpose Buffer" which can be found in the online examples. It implements an on-board program which fills a general purpose buffer. Most importantly, it runs continuously and independent of the motion or stops of the various axes. Hope someone else finds it useful.
Still curious if this is really the easiest way to accomplish this.

Verizon's new FiOS GigE Wireless N Router and High Speed Internet

So I got a deal in the mail to get an upgrade to [50/25] Mbps Internet (I currently have [15/5]...when I was reviewing it on line this message came up...
Verizon will provide up to [50/25] Mbps Internet with a wired connection. If you use your Internet primarily for wireless or WiFi connections, you have the option to upgrade to Verizon's new FiOS GigE Wireless N Router which will maximize your speed delivered through your wireless connection.
Upon completion of your order, you'll be provided with information for purchasing a router at Verizon's online equipment and accessories store.
I am VERY interested in getting super fast internet...my current internet is really good but it wouldnt hurt to bump it up. I have several devices using internet in the home...most of them wireless (including my PS3). I currently use a Verizon Actiontec router.
So here is my question...do I really need to get the above router to take advantage of that [50/25]? Also one other thing...My house is fairly large and I would really like to have two routers...is it possible to use two routers or a setup to have one upstairs and another downstairs?
Thanks in advance for the answers!
-Jest

There are a lot of variables that affect wireless range.
Walls, interference, other networks in the area, etc.
You don't indicate which older Actiontec you have.
Wireless capabilities also vary by Actiontec hardware revision (A,C,D,E,F,G,I).
In general, wireless range for 802.11n is somewhat less than 802.11g, even though the bandwidth is higher.
This is especially true on the 5Ghz band (which the latest Actiontec doesn;t support).
If you only need another 10 feet, you could try moving the router, or replacing the antenna with a high gain antenna.

I just set up an Optus Cisco DPQ3925 wireless router to access higher speed internet I signed up for. I have a 4th gen airport extreme I want to put in another room and use as a wifi extender the wifi but I get an error message each time I try. Help?

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.

HT204400 I have an old single 2.4 ghz router. If I upgrade to a new high speed router will I get better streaming video?

I Have an old single 2.4 GHz router. If I upgrade to a new high speed router will I get improved streaming of videos?
thanks.

It depends on what's rate limiting - if it's your wifi maybe, if your internet connection is slow the router won't make a huge difference though some products are better with poor lines.
Can you hook up a laptop to the router via ethernet and test the internet speed via speedtest.net?

I have one application that has requirement to do low and high speed acquisition. I want to change sample rate while running. BUT... I have E series Device

I am writing control software for a process that is usually dull and
requires only 10 Hz acquisition rate. At particular times during
the sequence, however, we are interested in looking at a couple of
channels at 1000 Hz. My approach so far is to configure my
Buffered DAQ to run at the higher rate at all times. When we are
in the 'high-speed DAQ' mode, the program logs every point to
disk. In the 'low-speed' mode, I am picking off every nth (in
this case, 10th) point to log to disk. At all times, I update my
GUI indicators on the front panel at a maximum of 4 times per second (I
find that anything faster results in an uncomfortable display), so I
fill up a FIFO with data in my acquisition / logging loop, and read the
FIFO in the display loop. The data in my GUI display can be up to
250 milliseconds off, but I find this acceptable . As a side note, I
need buffered Daq with hardware timing, as software timing results in
lost data at 1000 Hz.
This all works fine and dandy, but I am convinced that it is not the
most elegant solution in the world. Has anyone developed a
buffered DAQ loop where the scan rate can be adjusted during
operation? I would like to change the rate of the E-Series card
rather than relying on down-sampling as I am now doing.
The reason I have concern is that at the moment I am simulating my AI
using MAX and when running the down-sampling routine, I consistently
miss a particular event on the simulated data becuase the event in
question on the simulated data always occurs at the same 'time', and I
always miss it. Granted, while it is unlikely that my measured
signal and my acquisition are perfectly synchronized in the real world,
this particular situation points out the weakness in my approach.
More than anything, I am looking for ideas from the community to see
how other people have solved similar problems, and to have you guys
either tear apart my approach or tell me it is 'ok'. What do you
think?
Wes Ramm, Cyth UK

Adding to Alan's answer:
One of the problems that comes with these tricks for variable-rate acquisition is being able to match up sample data with the time that it was sampled.
If you weren't using either of E-series board's counters, there is a nifty solution to this! You'll be using 1 of the counters to generate the variable-rate sampling clock. You can then use the 2nd counter to perform a buffered period measurement on the output of the 1st counter. This gives you a hw-timed measurement of every sampling interval. You would need to keep track of a cumulative sum of these periods to generate a hw-accurate timestamp value for each sample.
Note: the very first buffered period measurement is the time from starting the 2nd counter until the first active edge from the 1st. For your app, you should ignore it.

New FiOS GigE Wireless 'N' Router has slowed our wireless speed to a crawl...need help!

This past Tuesday I installed the new N router. Also, we upgraded to FiOS Quantum 75/35 (previously 15/5). That was activated the following day. I can't complain about the internet speed to our pc since it's wired. Speed tests showed we were getting what was advertised. :-)
For the wifi, I can't figured out for the life of me what's causing our devices (e.g., our Nexus 7 tablets) to have a link speeds of 65Mbps one minute and then drop down to 5 or even 1. The same situation was happening with my HTC Incredible II phone, but I think that connection was tapping out at 54Mbps. The bottom would just drop out of the signal for some reason. Other times we couldn't even connect back in. The devices would say they're not in range even when they were in front of the router. Not sure if I fubarred the router install or what? I just swapped out the current Fios router for this new one. Pretty straightforward. At first, I logged into the router software with the defaults, but then I changed the the username, pswd, SSID, etc. to match what I used previously. I thought it was working fine the night of the install but not so much after Fios got bumped up in speed the following day. Maybe just a co-inky-dink?
I know you never get the same speeds compared to a wired pc but this seems worse (wifi-wise) than before the new router came along. I've read that the 'N' routers can be finicky to set-up to run properly. Maybe a setting or two is off?
I don't know if the fact that my son's netbook's wifi card is only b/g compatible would slow our network down? At this point I'm grasping at straws! I talked with tech support last night for 40 mins to no avail. I got the usual story about wireless devices running slower than wired ones, that these smaller devices aren't capable to maintaining higher speeds (which I'm not sure I agree with 100%), the more active devices you have slows down your network, etc, etc. I get all that. But something is going on or actually, it's not. LOL!
Why I don't agree with the above statement I mentioned is because I have my tablet at work now and the wifi speed is 54Mbps and it's constant. So it seems to have no problems with this speed, unlike what I was told over the phone.
Let me know if I can provide any further technical details that'll make it easier to help diagnose our wifi issues.
Thanks for listening to me whine ,
-bill

Thanks for the help, Hubrisnxs.
Here's an update since I got home:
Nexus7 (N7) took a min or so to connect to wifi when I got home. When it did, speed said 65Mbps. So I ran speedtest.net and got 27/20. Shortly after that I tried again but it was hesitating. I checked the speed and it was down to 5Mbps. Brought it upstairs to router and pc, and eventually it was back to 65. Ran speed test a few more times with similar results. I did notice that the connection would intermittently come and go. Not sure why. Looking at the wifi section on my N7, it says our network is out of range and the N7 is 2' from the router. Every now and then my network will go to the top of the list and it'll say it's obtaining ip address, then secured with wpa/wpa2 psk and it's locked in. So I hit the connect button and it's out of range again. Of course, while I was typing it decided to connect after 10-15 mins of trying/nothing. Says, signal strength excellent, 52 Mbps. Spoke too soon. It's off again. Crap! Back on again but speed was 19, now 5.
I did check router settings and this is what I have:
Performance mode ('n')
WPA2 AES
Channel 1
nonbroadcasting SSID
Maybe I'll try channel 11 next.....

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!
