Analog Source Triggering with more than one channel in channel list

Hello,
I am trying to use an analog reference trigger with a channel list that contains more than one entry using a
M Series 6289. I am aware that this is generally not possible to have more than one channel in the list due to hardware limitations. I was hoping if some sort of workaround exists.
I am using the NIDAQmx C API to control the card.
Using a second card that is syncronized via RTSI should
allow me to use an analog reference trigger to control multiple analog IO channels ... Right ???
Thanks for any advice!
Best regards
Peter

Hello Peter,
If you look at the NI-DAQmx Help, Analog Triggering Considerations for E Series, M Series, and S Series Devices section, it says that to pause multiple channels with an Analog trigger, you must wire that signal to APFI0 or APFI1. Therefore, it is possible to perform this operation.
If you are sharing the AI Sample Clock across RTSI, then you would be able to stop multiple AI channels across multiple devices with the one Analog Reference Trigger.
I hope this helps,
Sean C.

1.5.4 p 2: Filtering triggers with more than one criteria does not return

I just recently installed SQL Dev 1.5.4.59.40 updated to patch 2 using JDK 1.6.0_06.
I did not migrate settings from a prior version but rather applied them manually.
When applying a filter to the triggers node of a connection, a single filter works fine, or a multiline filter with a match criteria of all works fine, but when choosing Match Any with multiple (in my case 2) match criteria the filtered list of triggers fails to display in a reasonable amount of time.
The same filter criteria works relatively quickly in SQL Dev 1.5.1.54.40.
The connection in question has 2661 triggers that belong to it's schema.
I don't percieve any lack of performance on Schemas with smaller numbers of triggers (~20 triggers)
Also similar filter criteria work well on:
<li> Tables: 1300
<li> Packages: 41000
<li> Views: 27000

Just to be sure it's still an issue, can you try that on the latest 1.5.5?

Create a logical column with more than one data source

I'm having a problem to create a logical column with more than one data source in Siebel 7.8.
What I want to do is the union of 2 physical tables in one logical table.
For example, I have a "local_clients" table and a "abroad_clients" table. What I want is to have a logical table "clients" with the client data from the 2 tables.
What I've tried is dragging the datasources I need onto the logical column.
However this isn't working because it only retrieves the data from the first data source.

Hi!
I think it is not possible to do this just by dragging the columns to the logical table. A logical table can have more than one source, but I think each column must have just one direct source column.
I'm not sure, but maybe you should do the UNION SQL to get the data of the two tables. In the physical layer, when you create a new physical table, it's possible to set the "table type" as a "SELECT". I didn't try that, but it seems that it's possible to have the union table in the physical layer.
Bye.

Error using pretrigger when capturing more than one channel

I am having problems acquiring data with pretrigger samples when capturing more than one channel, using NI-PXI-6071E hardware and Labview's Analog Input VIs (Legacy NI-DAQ).
My goal is to trigger on one signal, while capturing another. Unfortunately, I cannot use the PFI0 for external triggering, as our cables/hardware have already been built, so I must use an analog input channel as the trigger. I understand that to do so I must capture both channels, and the channel that I wish to trigger off of must be the first channel in the list.
If I trigger and capture on the same channel (tried 1-4) then it
works great, regardless of the number of pre-trigger samples set. If I
capture more than one channel (passing the trigger channel first), with no pretrigger samples set, then triggering and capturing both work fine. However, if I do the same with the pretrigger sample > 0 I get the following error:
Error -10621 occurred at AI Control. Possible reason(s):
NI-DAQ LV: The specified trigger signal cannot be assigned to the trigger resource.
I don't se any such limitation explained in the user manual, and searching the forum, I have found a few other people that had the
same
problem
but they did not have solutions. Any ideas?
Solved!

I'm sorry for double-posting this. I was trying to post it in the DAQ board and it kept ending up on the LabView board.

Error while running spatial queries on a table with more than one geometry.

Hello,
I'm using GeoServer with Oracle Spatial database, and this is a second time I run into some problems because we use tables with more than one geometry.
When GeoServer renders objects with more than one geometry on the map, it creates a query where it asks for objects which one of the two geometries interacts with the query window. This type of query always fails with "End of TNS data channel" error.
We are running Oracle Standard 11.1.0.7.0.
Here is a small script to demonstrate the error. Could anyone confirm that they also have this type of error? Or suggest a fix?
What this script does:
1. Create table object1 with two geometry columns, geom1, geom2.
2. Create metadata (projected coordinate system).
3. Insert a row.
4. Create spacial indices on both columns.
5. Run a SDO_RELATE query on one column. Everything is fine.
6. Run a SDO_RELATE query on both columns. ERROR: "End of TNS data channel"
7. Clean.

Thanks for help.

This error appears in GeoServer and SQLPLUS.
I have set up a completly new database installation to test this error and everything works fine. I tried it again on the previous database but I still get the same error. I also tried to restart the database, but with no luck, the error is still there. I geuss something is wrong with the database installation.
Anyone knows what could cause an error like this "End of TNS data channel"?

Problem with more than one item in a track

DVDSP 4.0.2 / OSX.4.2 I've built a DVD with several tracks. In each track I've placed several .m2v files, one after another. Finished build plays fine on my Mac and on one of my stand alone DVD players. But on another stand alone (Sony DVP-S360) something very odd happens. DVD begins to play just fine, but whenever it encounters a track with more than one source file, it will play until it gets to the spot in the program where the second source file is in the track and then it hangs and won't do anything. I'm just curious if anyone has any insight into this problem. Is it a DVDSP conflict thing with certain players? Or is this Sony player just not capable of playing a DVD built this way? Thanks.

This page here:
http://www.videohelp.com/dvdplayers.php?DVDnameid=428&Search=Search&
has someone talking about finally getting burned DVDs to work, which suggests they previously had problems. I can't think why the track would not seem like continuous video, as if it had always been that way. Our Sony DVD player at work seems sensitive to higher data rates. What data rate did you use?

Can i record with more than one audio interface

I need to record 16 tracks, I have two different audio iterface, in GarageBand i can only find one of them, if i go to prefrenses-audio, I can set any of them as my audio interface, but only one at the time.
Any tips to how I can use bouth simultanious? Cubase, Logic mabye, GarageBand no can do? :-)

GB can only record 8 tracks at a time, however that is 16 channels, so with some extra effort you can get the outcome you desire, see the second tip here:

Sample code with more than one ResultSet in JSP

Hi
Can anyone give me sample JSP code using crystal reports JRC with more than one ResultSets which works, since mine always seem to be giving error .
Thank you

You can access the JRC samples from SDN in the Business Objects Portal. The link to them can be found [here.|https://smpdl.sap-ag.de/~sapidp/012002523100006008982008E/crxi_r2_jrc_web_smpl.zip] There is a sample called jrc_resultset_datasource that shows how to pass a result set to a report; you can use this and modify it to allow another result set to be passed in.
As a note, if you are having issues and believe it is your code, start with the sample and take small steps when adding new functionality so that you can determine where things go wrong.

6602 more than one channel

"i cant choose more than one channel on the daq assistent vi to measure.
how is it possible to measure more channels?
my other measures in this vi are done with the traditional daq.
i would like to do this with the 6602 too.
please give me an easy vi or explanation.
is it possible to combine traditional daq and daqmx?"

You're right!
There are two alternative solutions I can think of.
1. Go into MAX (I use v3.1) and create DAQmx global channels for each counter. For example, create CounterFunction0 for channel zero, CounterFunction1 for channel 1, etc. To do this go to Data Neighborhood>>NI-DAQ Global Channels and right mouse click and selct create new NI-DAQmx channel.
After creating these channels, create a NI-DAQmx task.
To do this, go to Data Neighborhood>>NI-DAQ Task and right mouse click and selct create new NI-DAQmx task. When creating the task, you can now select multiple global channels with the shift key. Make sure you click on the global channel tab to enable the view of the global channels you just created.
2. Without usnig Max you can
create a listbox in the LabVIEW front panel and select whatever counter channel you need. You can then convert what is selected into the proper counter string (Dev%d/ctr%d)and then pass this string into the taskID input. Remember, the taskID input in the DAQmx VIs can accept string inputs.
I hope this helps.

I want to acquire data for multiple channels using PCI 6120 that works on traditional DAQ. I cannot access more than one channel, can someone help me or if someone has data acquisition vi for PCI 6120, please send me over . Thanks

I have PCI 6120 card and I want to acquire data for more than one channels. I'm using traditional DAQ to get it. But it does not work for more than one channels. If someone has a data acquisition vi for PCI 6120. Or some suggestion how to aquire data please let me know.
Thanks

Hello DSPGUY1,
You can definetly acquire from several channels. For your convenience, I have appended below the content from help that tells you how to configure it:
"channels specifies the set of analog input channels. The order of the channels in the scan list defines the order in which the channels are scanned during an acquisition. channels is an array of strings. You can use one channel entry per element or specify the entire scan list in a single element, or use any combination of these two methods. If x, y, and z refer to channels, you can specify a list of channels in a single element by separating the individual channels by commas, for example, x,y,z. If x refers to the first channel in a consecutive channel range and y refers to the last channel, yo
u can specify the range by separating the first and last channels by a colon, for example, x:y."
Hope this help.

Reports 9i Graphs with more than one query..

Hello,
I am converting my 6i reports to 9i reports. On my graph reports with more than one query, when I invoke the graph wizard it changes the value of the src to the wrong query automatically. When I run my report, I am getting the error REP-0069 Internal Error rwlib-1: REP-6219 Column (Column Name) not in given cursor hierarchy. Although it's a pretty easy fix to go into the graph settings in the property palette and change it back, it is extremely frustrating. Has anyone else ran into this problem and did you find a permanent fix?
Thanks,
Laura

Hi Laura
One workround would be to create a new query in the Data Model that includes desired fields, and then source
chart to the new group.
FYi, bug2527100 was filed on this issue and is already fixed. The fix would be available in 9i Reports 9.0.2.2 patch. Reports 9.0.2.2 patch is scheduled to be released on Mar 05 2003 (tentative date).
Thanks

Writing more than one channel to a file using Xaincnbg VI from the Universal Library

Hi,
Could anyone help me with writing more than one channel to a file? I am using the Universal Library version 5.40 with LabView 7.0 with the Xaincnbg VI.
With one channel everything in my program works beautifully, but when I add another channel and graph and wire it to the Write LVM only one channel ends up being written to the file. It seems like there should be some function that works to add the two output arrays or something of the sort, but I can't seem to find it.
If anyone has come across this problem or knows of how it might be solved, I would really like to hear about it!
Thanks

Oops, forgot to attach the files...
And, pics of the VI's, in case you don't have LV8.2

Is there a stereo bluetooth headset that can pair with more than one device at a time?

Is there a stereo bluetooth headset that can pair, i.e. multipoint, with more than one device at a time?
Are the MacBook and iPhone 4 capable of multipoint bluetooth technoloagy?
The goal is for my wife to be able to watch her Korean TV soap operas on her MacBook and still receive a call on her iPhone 4 via a stereo bluetooth headset.
I was looking at the Motorola S10-HD but after further review saw that it only pairs with one device at a time.
Appreciate any and all input. My Googling has returned no results.

You can only pair one device at a time to your 8330, or any other phone for that matter. The "pairings" are saved to the phone, you can use one or the other and you won't have to pair it again. Once you turn your bluetooth device on and the phone is on, they will find each other again.

Can I use a magic trackpad with more than one Mac at a time?

I am attempting to pair a MTP with a second MacBook Pro. So far I can't get system preferences to find the MTP.
I am wondering whether the MTP can be paired with only one Mac at a time, and that this is why my MBP won't find it.
The reason I am thinking this is because the little booklet that comes with the MTP says 'after you pair your MTP with a Mac, you can pair it again with a different Mac. To do this, you first remove the existing pairing and then pair the trackpad again'.
Can anyone advise, please?
If it can be paired with more than one MBP at a time, any suggestions why my system preferences search for the MTP is not producing any results?
Thanks

Yes, your keyboard, mouse or trackpad can be paired with multiple Macs. You can even have multiple keyboards, mice or trackpads paired with one Mac. The caveat is that the device can only be connected to one Mac at a time. The device can't be paired or connected with a Mac while it's currently connected to another.
Pairing a device with 2 Macs will be troublesome if the Macs are located within 33 ft of each other. The device will connect with the first available paired Mac and then unavailable to the second. If the Macs are located outside the 10meter range, it's quite easy to power off the keyboard (forcing a disconnect) then walking the keyboard to Mac 2 and powering the keyboard on. I do this with a keyboard from my iMac to a Mac Mini in another room.
