How to set a I/O channel in NI PXIe-6556 to ground when in PMU mode

Is there a way or API call in LabVIEW to set any one of the channels to ground within the PXIe-6556 when in PMU mode?
Solved!
Go to Solution.

If you disconnect the PMU, you will have the option to go to tristate or your previous digital state, but not ground. Forcing 0V is probably the closest you can get to a GND like behavior. The default line state is tristate for this device, which will leave the line floating if there is no active driver.

How to set up a RSS channel via portal

Hi,
I know this question is very simple to some but I am a newbie. But I know that we need to use the xml channel to create a rss channel. I am trying to use the swforum rss channel as my example. But where do I find the info for the xslFileName and where to put it?
A step by step will be appreciative.

Hi
I am not sure If I have understood your question correctly.
If the question is how to set up batcj jobs using lsmw the following steps should help:
1. Create a recording for the set up of batcj jobs(t-code SM36)
2. Specify the fields like batch job name, class, user, program, variant and the frequency. Some values might be constant.
3. Complete the LSMW script. This will create a batch input session. Use t-code SM35 to process the session either in background or foreground. You can check the batch jobs created using t-code SM37.
However if your question is relating to how the batch job is set up to upload files using lmsw, then once the script creation is completed, then a batch input session is created and has to be processed using SM35. It will create the open items/master data using the t-code mentioned in the recording of the lsmw.

How to set up the communication channel for third party idoc

Hello,
I am trying to send an idoc from an sap 4.6c system to an third party system. The third party system is supporting idcos with trfc.
My problem is to set up the communication channel in the integration builder (configuration) for the third party system. The idoc is waitung in XI to transport.
My settings are:
adapter type: idoc
transport protocol: idoc
message protocol: idoc
adapter engine: integration engine
rfc destination: xyz (is working fine)
interface version: sap release 4.0 or higher
port: ??
sap release 46c
My problem is the port. should i set up a port in idx1? But the third party is not an sap system and so i dont have a client.
On the xi i have defined a port in transaction we21 (transactional rfc) for the third party with my rfc destination xyz. But if i enter that port in communication channel i got error messages.
Thanks for any help.

Hi Christian,
yes, you have to mainztain that port in idx1.
First ypi load the rfc-metadata from an SAP referenzsystem and afterwards copy this metadata to the third party port.
For further details check the onlinedocumentation "IDoc Processing with the IDoc Adapter" XI -> runtime -> adapter
Good luck,
Holger

How to set the specified communication channel invisible in RWB?

Hi,gurus:
We have many communication channels in our XI server.
You know that we can filter the communication channel in communicaiton channel monitoring.
Are there other methods to set the specified communication channel invisible in RWB without using filter or deleting the communication channel?
Thanks in advance.

Hey,
>Are there other methods to set the specified communication channel invisible in RWB without using filter
NO - To my Knowledge,
In RWB - you can stop/inactive the Adapter

How to set audio hardware input channels for narration & to what?

Searched forum - hope I didn't miss solution for the following:
Using PE3 in Windows XPSP3
Tried for the first time to add narration to a project. Was using a stereo/microphone headset. Got nothing but noise. Could record in Windows recorder and Audacity. However, the microphone as part of the set would not work in Windows Audio Hardware Test Wizard. The set was using a sound chip on the motherboard.
A friend of mine has the same OS, motherboard and is using PE3. He too had never tried adding narration - but tried with a USP connected set, and was successful.
I removed my stereo set, and connected a USB set. To make sure all settings were reset, I did a cold reboot. The USB set worked in Windows Audio Test Wizard. I opened my project again, and in Edit/Preferences/Audio Hardware, clicked AIIO Settings. Unchecked the old set (Realtek) in both the Output and Input Ports area, checked the USB Audio Device, moved to the top of both lists.
Then tried to add narration and got the error message "Your current audio hardware selection does not have any input channels. Please use Preferences>Audio Hardware to correct this problem.
Thinking that maybe this was a preset for the project and couldn't be changed, I started a new project, no video, just tried to add narration, and got the same message.
The entries in the columns in the ASIO Direct Sound for Full Duplex Setup menu for the USB Audio Device in the Input section are: 2048, 0, 1, 16, Yes
The only one of these that seems to be able to be adjusted is the second number - the Offset (Samples). The Audio Channels number is set to 1 and doesn't seem to be changeable. Suggestions?

When working with Audio in most NLE's, i.e. Premiere Elements, or Pro, there are basically three areas that can affect how the Audio is handled on one's system. First, there is the Sound settings in Windows (from Control Panel). Next, the Audio card/chip probably/possibly has a console to make settings at the card/chip level. Last, and these are really two locations, but I'm only counting them as one since they are both in the NLE - Edit>Preferences>Audio & Audio Hardware. This is where Steve is referring to. Check all settings, and I'd suggest doing so in the order that I listed them above: OS, Audio card, then Premiere. A Mute, or by-pass in the first two, can override the settings in Premiere, and you may have its setting correct, but still not be able to effectively use your hardware.
The exact settings chosen will depend on the exact hardware that is properly installed. Without knowing all of your hardware and other settings elsewhere, one cannot give you a definitive answer. Ideally, in the settings drop-downs, you *should* see your hardware listed. Look closely, as these can be a bit cryptic.
If you are still unable to get your hardware working properly, a fourth place to look would be Control Panel>System>Hardware>Device Manager for your Audio hardware. Check that Device Manager sees your hardware, and that it is working properly.
If all is set up properly, but still not working, report back with exact specs on your system, including all of your Audio hardware. There are possibly some more steps that can be taken. I will not mention them now, as they *should not* be needed. If you do need further assistance, please list every option in all of the drop-down lists from Premiere, so we can know what your choices are.
Good luck,
Hunt

How to Set Left/right audio channel while Video playback

how can I controlling the left / right audio channel while video playback, I can't find any method or class for this in JMF, anyone that can direct me how to do it?

The way I found to control two stereo channel is to implement a plug-in Effect that will control two volumes (left/right) indipandently.
You can start from the example GainEffect from sun, and implement your control.
For eample, if you want to mute the left channel, simply set to 0 all the odd samples (or even...I don't remember exactly, try it).
You have then to add you plug in to the processor chain... again see the examples.
More complex effects (panning etc) can be done in the same way, but it seems to me that it's quite CPU intensive.

Anyone know how I set up a new project at 1920x1080 59.94i fps ntsc when none of the presets match?

I have just bought Adobe Premiere Elements 10 here in the UK for my laptop: Windows Vista, 32bit OS, 2GB Ram.
I am editing a video I shot in NTSC format at 1920 x 1080, 59.94i frames per second (MPEG2 HD Long 35mbps), from a Sony XDCAM EX1 camcorder.
I notice that none of the Project Set Up Presets in Adobe Premiere Elements vs 10 have this matching format.
Therefore when I drag my video and play it on the timeline in a 30fps file set up, the frames per second is not matching the sound and it's jumpy!
Can I download any XDCAM EX1 camcorder presets for Adobe Premiere Elements 10? like there are for Adobe Premiere Pro CS5?
Also, will I have to upgrade my laptop for it to run properly?
Many thanks for this (from a really frustrated Editor, who is based in London and has already spent 5 months trying to get a Nero edit software working, and has replaced this with Adobe, because Nero finally admitted that their software doesnt work with MP4s!!!)

Yes, I agree with both of you. I understand that my camera may be more expensive than the edit software I am using. I am making a birthday video surprise for my brother's 40th birthday party. He lives permanently in the USA. I live in London. I run my own Video Production company. Therefore I cant edit a less-than-high-definition video, as it would look bad on my business. So I have been very prepared and shot it in NTSC format at a high res. The unfortunate thing is that I cant (without distress) take my desktop computer on holiday with me. That leaves me with a very basic laptop to edit all the stuff on. When I get to the US I will be filming the American relatives using the same camera, but Adobe Premiere Elements 10 is obviously not up to the job (as with my laptop - although I'm looking to upgrade my laptop to a better spec, without spending a fortune, although I cant change the Processor without buying a new laptop). So that is the conundrum I face. When you see these adverts on television for a news channel and you see the news anchor in a dangerous place with bullets flying past them and they're sitting at their laptop editing, or transferrring footage from the piece they have just done, it's all a load of "bollox" (excuse my French), because basically there isnt a laptop out there, or software that can handle high definition footage! By the time it takes me to figure out all of this I could have learnt to write my own editing software! (by the way, I am a massive fan of all things ADOBE). My friend, used Adobe Premiere Pro to edit the film 'Monsters' and he's about to direct the next Godzilla movie!!!!!! So yes, it is fantastic. Steve, I have just uploaded the preset you suggested, however, the clip on my timeline isnt quite right. When I play the clip from the XDCAM clip browser software it is fine and plays at normal rate with sound and visuals in sync. However, when I play in the software the visuals play at half the speed of the sound/timeline line. When I run my processor guide it shows that just to play the clip the processor is at 100%, so I guess that the software might actually be working ok, but actually it's my laptop at fault. Although on the side of the Adobe Elements box it doesnt specify what processor spec you need to run the software. Oh deary me. Looks like it's back to the drawing board and that my bro isnt going to get his 40th birthday surprise video after all.....boo hoo! (I am only a girl after all! and so all of this is beyond my comprehension anyway...I should just go back to cleaning the dishes)!!!!!! Thanks very much for your advice! Lynds x

How to set Lov item property (Action type,event,parameter etc) in PR when page load

Hi gurus
I am new to OAF, First I need to explain my scenerio.
I need to make some field mandatory or non mandatory based on one LOV item (Pick list or message choice list).
for this i extended the controler and apply the changes, but in this case what heppen, It will effect only when i open the list (pop list) and click on more (Available in poplist) and it will open a new form and i select value from that form. But when I open the poplist and select the value from the same list rather going to more option (it does not open new form), then there are no effect. I though the issue with refreshing when selecting value from the same list.
To resolving this issue what i did
1. go to page == > the same LOV
2. Change the Client Action properties (
     Action type = fireAction
     event          = xxevent
    submit = true.
After doing this when i run the page from my OAF enviroement , every thing is OK. Then I transfer the Controler to Server machine and change the controller and run the same page from the server, it has the same refreshing issue, Then I thought because I did not transfer LOV such properties so this is hepening,
Now I want to initilize such properties in Page load or what I need to do, Please advise me.
Regards,
Haq

Edward,
Thank you for the suggestion! It directly lead to my solution wherein I used CASE statements for the column in my Region SELECT such as the following:
WHEN (:P2_GRADING_METHOD = 'CR/NC' OR scs.scs_pass_audit = 'P') AND GET_GRADE_B93 (sac.stc_final_grade, sac.stc_verified_grade) IS NULL THEN htmldb_item.select_list_from_lov (5, 'Enter Grade', 'GRADE_LOV_CRNC','onBlur="return validate_grade(this,''FW_DATE_'||ROWNUM||''')"','NO',NULL,NULL,'GRADE_'||ROWNUM)
When the column is NULL, the Select List (LOV) contains the entry 'Enter Grade' and that is the value displayed on page load. I bypass the value 'Enter Grade' during Submit Processing where database updating occurs.
I did not find the need to enter values for p_null_value and p_null_text since I don't believe that it would cause the 'Enter Grade' value to display on page load for null value columns but rather would enable the user to select 'Enter Grade' from the list and have a specified return value stored in htmldb_item array.
Again, thank you for the help!

How can I set up a Mainstage channel strip to recognize coarse detune?

Can anyone clue me in on how to get Mainstage 2 to recognize coarse detune? Right now I have it set up so that a mainstage channel strip recognizes standard pitch bend messages and I can set the pitch bend range of the associated instrument to 12 (the default for the channel strips appears to be 2), and so standard pitch bend works fine.   But when the pitch bend messages I'm sending are coarse detune, I'm getting zip...nada...nuttin -- even when I have set the pitch bend range for the instrument on the channel strip set to 12.
I don't want to just offset the pitch by a set amount; I want to use coarse detune to bend the pitch by semitones during a performance. If anyone here has any suggestions or knows how to make this happen, I'd really appreciate your help --
thanks in advance,
Lipp

Hi
The default bend range is set within the Instrument plugin setting associated with a channel strip.

This could depend on the Instrument plugin (which on eare you referring to?).
Try making a knob or fader object in Layout mode and MIDI learn it to incoming PitchBend messages, then map that control to the dtune function.

How to set AO channel to 0 value when VI stopped

Hi!
As a second option (and if your device supports it ) you could set the property "Idle Output Behavior"
