Routing signal through PXI_Trigger to RTSI

PXI-6224 DAQ Generates a pulse through CTR0/PFI12 port. When the pulse reaches its trailing edge,PXI-5122 digitizer starts to acquire a voltage waveform.
I think it should be done with routing signal through PXI_Trigger to RTSI,like my vi attached. But to the item I test,there is no referenced result,I am not sure if its result correct,even though the vi works OK. Please help me check it,thanks.

Thank you for your answer,
I'm now sure that its not possible to detect the analog signal level from the multiplexed signal arriving on DAQ 6052E.
What do you think about a hardware solution which would consist to use an other 6052E DAQ on which the multiplexed analog signal would be connected.
I think this way has to be explored but I don't know exactly the CPCI pin used to multiplex signal.
Thanks for all

Route signal from pxi 6602 to RTSI

Hi,
I have a problem to export pulse from pxi 6602 to RTSI0. The code is simple as follows:
DAQmxCreateTask("",&taskHandle);
  DAQmxCreateAOVoltageChan(taskHandle,"AO/ao0","",-10.0,10.0,DAQmx_Val_Volts,NULL);
  DAQmxCreateAOVoltageChan(taskHandle,"AO/ao1","",-10.0,10.0,DAQmx_Val_Volts,NULL);
  DAQmxCfgSampClkTiming(taskHandle,NULL,1000.0,DAQmx_Val_Rising,DAQmx_Val_ContSamps,2);
  DAQmxCfgDigEdgeStartTrig (taskHandle, "RTSI0", DAQmx_Val_Rising );
  DAQmxWriteAnalogF64(taskHandle,2,0,10.0,DAQmx_Val_GroupByChannel,out,NULL,NULL);
  DAQmxCreateTask ("", &countHandle0);
  DAQmxCreateCOPulseChanTime(countHandle0,"TimingIO/ctr0","",
   DAQmx_Val_Seconds,DAQmx_Val_Low,1,0.5,1);
  err = DAQmxExportSignal (countHandle0, DAQmx_Val_StartTrigger, "RTSI0");
//  err = DAQmxConnectTerms ("TimingIO/Ctr0Gate", "RTSI0",DAQmx_Val_DoNotInvertPolarity );
  DAQmxStartTask(taskHandle);
  DAQmxStartTask (countHandle0);
the lines at DAQmxExportSignal(..) and DAQmxConnectTerms(..) both generate big negative number, I spent hours and no answer. In fact I have to use the counter to trigger other boards in my project, I plan to use the route signals a lot.
Sincerely,
Taishan

Hello Taishan,
Thanks for contacting National Instruments.
When you are using DAQmx with a PXI system, much of the signal routing can be handled implicitly by the driver. From your code, it appears that you want to use a counter output to start an analog output task. Please let me know if this assumption is incorrect.
When used while configuring your analog output task, the following function will cause the internal output of Counter0 to be routed automatically over the PXI backplane to the analog output device. I have assumed that your PXI-6602 is in slot 2 of the PXI chassis.
DAQmxCfgDigEdgeStartTrig (AnalogOutputTaskHandle, "/PXI1Slot2/Ctr0InternalOutput", DAQmx_Val_Rising);
The tutorials Getting Started with NI-DAQmx and Learn 10 Functions in NI-DAQmx and Handle 80 Percent of Your Data Acquisition Applications are great starting points for programming with the DAQmx API. Since you are using C, Using NI-DAQmx in Text Based Programming Environments, is a great starting point for comparing the LabVIEW API to the C API for DAQmx.
Please post back if you have any questions.

I can't get a signal through whole house because of a brick wall What range extender do you recommend to be used with my wireless router ( apple brand)

I can't get a signal through whole house because of a brick wall What range extender do you recommend to be used with my wireless router ( apple brand)

Very few 3rd party wireless extenders will work with an Apple router, so your best bet is always to use an extender that is the same brand as the main router. An AirPort Express is a popular choice for this type of application with another Apple router.
If you had a Cisco router, then a Cisco extender would be your best bet. Same for Netgear, etc.
But......a wireless extender can only "extend" the quality of wireless signal that it receives, and not much of a wireless signal is going to make it through a brick wall, so whether any extender might do what you want is open to question.
You won't know whether an extender using wireless to connect will work to your satisfaction in your home until you actually try it out in your home.
The performance will always be much better if you can connect the extending device back to the main router using a wired Ethernet cable connection.
If it is not possible to run the Ethernet cable, a pair of Ethernet power line adapters might be able to send the signal over the existing AC power lines in your home. The theory with these devices is that you already have the wiring in place, you just need the adapters.
In practice though, things do not always work as well as the theory might suggest, so if you decide to try a pair of adapters, it might be a good idea to understand the store's return policies before you buy.

How do I use AO update in the Route signal.vi

Hi support,
My goal is to create a waveform (to buffer it) and output it using the analog card (PCI-6713) N times and with the frequency F. Apperanlty this is done using a (actually 2) digital counter(s) on the PCI-6602 card.
This is done using route signal.vi using "AO update". However I have not managed to get it working. I only get error -10341. So my questions are how do I do it? More specificly how do I use AO update in the Route singal.vi Do I need to conect the cards in any perticular way (cabels or so)? Also do you have more information about how the vi route signal works (the help file does not help me much)?
Grateful for all help.
I'm using labview 6.0 as developpement platform, and using the PCI-6601, PCI-67
13 and a PCI-7344 cards. Since the program is quite large I will only send a portion of it, the pulseGen is supposed to generate the waveform (loaded as a text file, also submitted) the digital output used is in case 1 (in pulseGen) the analog output is in case 3. The MissingWaveform.vi is just to ensure that a waveform is supplied to the pulseGen.vi
Sorry about the mess.
/Chatri

Cabling and Interfacing between Boards: You have capability for direct simultaneous connection between 6713 and 6602 (also 6601) via the RTSI bus, but you need to get a cable to connect between the boards. You can connect between the boards using the I/O pins of their respective signal conditioning hardware. These connections are slower. There are also PFI (Programmable Function Interfaces) connections that are set within the VI's.
All that said, it is not obvious why you want to use the RTSI. You can use the PCI-6713 to generate AO. Presumably you have some signal conditioning accessory; which ever pin of that accessory the AO appears on, you wire it over to the SC accessory for the 6601 and the appropriate pin for the counter gate or
source you want to use.
Suggestions: Don't try to work in the context of your big VI for now. Get the AO bit and the counting bit to work together by themselves. Then shoe-horn them into the big VI. Also, consider a call to the NI help line. They are very good. 800.433.3488 (800IEEE488)
In case you hadn't noticed the DAQ cards and Counter/Timer cards come in different flavors and there are specific example VI's to suit. 6602 uses NI-TIO chip, but PCI-671X are DAQ-STC. Again the NI help people are good at catching this kind of stuff.
Your question is rather large and hard to manage. Perhaps if you break it down into small chunks the advise will be more free flowing.

How to program the daq card to route signals?

Hi,
I would like to program the daq card to route signals, for example from DIO0 to
DIO1. All this should happen without Labview, directly on the board. Is this possible?
What I want to do, is to get a lot of signals as inputs and output those
signals as they are. Sometimes I need to take one signal through Labview
and make some modifications to it. If I route all the signals through Windows
and Labview will propably cause latency, so I would like to do this at the lowest
level as possible.
Currently I'm using PCI-DAQ 6025E, but this card might not be sufficient for our
needs, so if this is possible with some other card, please share your information.
All information on this matter is highly appreciated.

Oops!. I just noticed that I accidentally posted this question to the wrong forum.
I posted a new one to "multifunction DAQ", so if you have something to say about
this matter, then go here

Routing signals PXI-6602

I'm trying to route a single input to more than one counter. I've been wading through the routing signals options with no success. I have a PXI-6602 and using LabView 8.20. I have a single input that I want to measure the period and pulse width on. Hooking up multiple external lines is an option, but I'm converting from fiber to the input so it would be much easier to route the signals internally.
My 6602 is Dev1. I can't seem to nail down how to use the route signals vi. I've looked at some examples with no more clarity. What's the easiest way to accomplish this task internally and is there a simple clear example?

I would wire to the PFI pins associated with the Gate input of either Ctr0 or Ctr1. These PFI pins are *not* shared with DIO functions so there's no chance of conflict with future DIO usage.
Both period and pulse width measurements should allow you to successfully specify any of the Gate input PFI pins as the signal source. You shouldn't need to call any explicit signal routing functions if you're using DAQmx -- it handles most stuff auto-magically.
Another option may be to configure for semi-period measurement. Depending on the polarity setting, the pulse widths will be either the even or the odd values in the measurement data. The periods will simply be the sum of adjacent pairs of values, though you may need to ignore the very first value in a buffered measurement -- it represents the (meaningless) time from starting the task until the first active edge.
Sorry, not at a LV machine to create & post an example...

Saffire Pro 24(Non DSP) Logic Studio 9 Signal through interface but no signal through logic, PLEASE HELP!

I recently purchased a saffire pro 24, rode nt1000 condeser mic, and Logic 9. My Problem is that I don't know how to get a signal through the DAW. There is a signal through the interface I can hear the mic through the head phones. With Mix Control I have the routing preset set to "DAW Tracking" with line output 3 and 4 set to Analog 1 so I can hear the Mic. All the other settings are untouched. On Logic I have everything untouched except for preference>audio I set the input and output to saffire with a buffer size of 256 but I can't hear ANYTHING through the DAW only the interface itself. Any help would be greatly appreaciated. This is my first studio set up I have toyed around with garageband a bit.

AndySeng wrote:
thanks! it worked while recording but the gain is real high on the interface for only a low signal on the DAW. How do you turn on monitering?
The Rode mic needs Phantom power, do you have that turned on? (if not, turn the input gain down first)
The audio interface will have a gain control for the mic, it may or may not have sensitivity switches that can give you more gain, either that or a trim control.
The software monitoring is well... right next to where you set your interface and I/O buffer.
Two cents of advice, reading the manual (over and over) of your hardware interface is a must. In order to make decent recordings you will have to know and understand your hardware. Same with Logic, it's pretty easy to get going on Logic but to use more than 2 or 3% of what the program is capable of the manual and online help is a necessity. Also your mic.
I tell clients that wish to learn Logic to pretend they have no Internet access, just the program and the manuals + online help.
They usually tell me to leave at that point.

Recording a Line Signal through Motu 828mk3 into Cubase, Please help!

Hello everyone,
So i use Motu 828mk3, pair of m-audio monitors, I have logic but find Cubase more compatible for my style. I want to record a line in signal from my DJ mixer (allen&heath xone 62, pair of Pionner cdjs-1000).
So i connect the main outs (xlr to 1/8") into my Motu analog 1-2 ins. The meter on the Motu reads the signal, i expected the signal to come through my monitors although they are silent. I dont understand what blocks the Main Outs of my Motu.(If i play a song on itunes or a sample in cubase it plays through my monitors)
I set everything correct on my Motu Audio Setup, i put Default input as my Analog 1-2, and default main outs as Main Outs.
The Cue mixer which comes with Motu reads the in signal also. I tried to get it connected though cubase too, but im assuming that once i get motu release the signal through my outs i will be able to connect it through cubase.
Seems like i tried everything in my knowledge, now i need your help. Thank you folks

Yes i checked on My system preferences, everything is there for Motu, it reads the input and it send out sound from itunes youtube etc.
In cubase, well first i feel like the input should come out the Main outs of the Motu even if wouldnt want to record anything right ?
And yes in cubase everything seems to be set to record, drivers are motu on, setting are set, the handle (little speaker) is on to record, in preferences of Device setup motu it set active.

Problems routing faxes through email

I have a Windows Server 2008 fax server that is giving me some problems when trying to route inbound faxes via email.
Sometimes it will work, and then eventually an inbound fax will get stuck with a status of "Retrying Routing" when viewing it in the Windows XP Fax Console on the client. When this happens, the fax server will record the following 2 events in the Application event log:
Event ID: 32083   Source: Microsoft Fax   Task Category: Inbound   User: N/A
Unable to route fax C:\ProgramData\Microsoft\Windows NT\MSFax\Queue\1C9889BC4B822.tif to the requested e-mail address.
The following error occurred: 0x80040211
This error code indicates the cause of the error.
Check the SMTP server configuration, and correct any anomalies.
Event ID: 32089   Source: Microsoft Fax   Task Category: Inbound   User: N/A
The Fax Service failed to execute a specific routing method. The service will retry to route the fax according to the retries configuration. If the retries fail, verify routing method configuration.
Job ID: 0x0401c9889bc4b822.
Received on Device: 'Conexant D850 PCI V.92 Modem'
Sent from: '123123456'
Received file name: 'C:\ProgramData\Microsoft\Windows NT\MSFax\Queue\1C9889BC4B822.tif'.
Routing extension name: 'Microsoft Routing Extension'
Routing method name: 'Route through e-mail'
Sometimes, the fax will eventually go through. Other times, it will fail completely. If it fails completely, the following event is logged in the Application event log and all faxes after this one will fail too.
Event ID: 32078   Source: Microsoft Fax   Task Category: Inbound   User: N/A
A successfully received fax was not routed automatically. You can find the fax in the Inbox/Incoming archive folder by its Job ID. Job ID: 0x0401c988900827e4. Received on Device: 'Conexant D850 PCI V.92 Modem' Sent from: '987-654-3210'
If I clear all the stuck faxes out of the "Incomming" folder of the fax console, then future faxes might come through successfully (by clear I mean delete them).
I followed the instructions from the following link to get an authenticated user set up instead of using anonymous, but that hasn't helped.
http://blogs.technet.com/sbs/archive/2007/04/02/inbound-fax-routing-may-fail-due-to-the-exchange-intelligent-message-filter-imf.aspx
Any help anyone has would be greatly appreciated as this is getting frustrating.
Thanks!

Hi,
According to your description, I understand that you have problem with routing faxes through email. You may implement the action plan below to address this issue.
Action plan:
================
1. Check Exchange setting.
2. Please follow SBS blog, check Exchange System Manager for the following setting and remove it if it exists:
http://blogs.technet.com/sbs/archive/2007/01/15/fax-fails-because-of-orbs.aspx
3. Disable your antivirus software and retest.
4. If you are running AVG 8 which has SPAM filtering capabilities. Go into Server Manager and configure the associated service to DISABLED:
5. Reboot the server and confirm the service is not running within Server Manager
6. Retest sending faxes to the server and note the results.
If the issue persists, then clean-boot the server and retest again. Use msconfig to disable all third party services and startup programs.
1.Launch MSCONFIG.exe on the server.
2.Under the General tab, select "Selective Startup" and uncheck all of the sub-items except for "Load System Services"
3.Choose the Services tab and then select the "Hide all Microsoft Services" option.
4.Click the "DISABLE ALL" button to disable the list of third-party services.
5.Choose the APPLY and the CLOSE button. Then Restart.

Tracing a route passing through ASA

Hi Everyone,
Need help on tracing a route IP 192.168.27.0 that is passing through ASA
i did sh route on ASA
S 192.168.27.0 255.255.255.0 [1/0] via 192.168.101.14, Xnet
so this means that this ASA is learning this route statically through int Xnet right ?
when i do sh int on ASA it shows Xnet as interface.
what should be my next step?
also i am able to ping this IP from ASA but whne i do sh arp it does not show this IP 192.168.27.251 and mac address
Thanks
Mahesh

So I presume you have ASA5550 or you have bought addiotional 4 GigabitEthernet module.
When you look at the ASA from the side where the physical ports are
The usual ports (without the module) should be in the Right side
The modules ports should be on the Left side
The module should contain 8 ports
4 Ports are for SFP slots (usually for fiber connections)
4 Ports are for basic Ethernet connectivity
The configuration should have some line "media-type" which defines which type is used "rj45" of "sfp"
rj45 for Ethernet
sfp for SFP module
So GigabitEthernet 1/2 port should be to my understanding either the Third Ethernet or Third SFP port of the module depending on the above port configuration mentioned (media-type rj45/sfp)
The ports GigabitEthernet0/0 - x are the ports that are in every ASA, Ports GigabitEthernet1/0 - x are the expansion modules ports
Hope this helps. Hopefully I remembered that right.

Computer "reverts" to weaker router signal instead of range extender

I've have seen some similar posts; but nothing seems exactly like my problem; or I've missed it.
I have a WRT54G Wireless Router and WRE54G range extender; seem to be working fine and talking to each other. (Took a while, but I got it; and it's been Okay since.) I have fast Internet when connnected to the stronger WRE signal and slow Interent when connected to the weaker WRT signal (which is farther away) - all as one would expect.
The problem: My computer (single location desktop) won't stay linked to the stronger "Range Extender" signal. I'll work awhile or walk away and come back - and the link will have reverted from the strong, fast Extender signal to the slow, weaker Router signal. I then go to my profile; connect and somtimes get back on the stronger signal. (If not, just try again and again until it locks back to the stronger signal.) [Same with "site survey" - I select connect to the stronger signal, but it seems to connect randomly to either.] <Also - I often get a "program error" and the adaptor software shuts down when I try to open it; it will start again automatically.>
-&- From another post, I think I might do something with MAC addresses - for example, block my USB Wireless receiver MAC from the router so it could "only" connect to the Extender. (Better yet, can I tell my network connection to only link to the Extender MAC?)
OS is 2000 -
Here is something I put together earlier - mostly just repeats above:
Equipment:
LinkSys Wireless Router; WRT54G; Ver 6. Firmware 1.00.7 (Now 1.02.7 )
LinkSys Range Extender; WRE54G; Ver 3 Firmware 3.01.01 (Now 3.04.01)
LinkSys USB network adaptor:   WUSB54G Ver 4
   - WHY does it keep reverting back to the weaker router signal? (The big question.)
- Why, when I do a site survey, select the stronger signal, and select connect, enter the WEP code, does it still sometimes link me right back to the weaker router signal, even though I've highlighted the stronger repeater signal when I hit the connect button?
- If I create profiles with the stronger signal it still acts the same (that is, sometimes it links to the stronger signal "Extender" signal and sometimes to the weaker Repeater signal, except I don't need to enter the WEP code if I connect to the profile instead of the sight survey signal.
- According to online information I've found the Router should be running "Firmware version 2.02.2" to be WRE compatible;   But - If I check for the latest version of firmware for WRT54G Ver. 6 it is 1.02.7 - Does this mean the extender is incompatible with my router?
- Is there a way to "force" the wireless network connection to link to a specific MAC address - so I can restrict it to the Extender's stronger signal?
Solved!
Go to Solution.

Scrooge, thank you for the suggestions.    Earlier I tried the following solution based on a some-what similar condition on another post:
Solution: Configure the router MAC filter not to allow connections from the MAC address of the USB Wireless network card.
Since I tried this a couple days ago I've been monitoring and it has been working. So, before it would keep switching to the weaker Repeater link. Telling the repeater not to allow the link leaves it only the extender to link to, and it is now staying linked to the extender and the faster speed is remaining steady.
