Universal method for serial identification

Hi,
Is there a universal method for obtaining instrument identification string for any type of serial instrument? Most national instrument serial device follow "ASRL?*instr" command but not everyone does. I just wondering if there is a real unversal method that will get IDs for any serial device attached that is very similiar to other data bus like GPIB/USB/Firewire/etc. I've also tried "*IDN?" command too but no avail.
Thanks

No. While some devices support that standard, there are many that do not. All you can do is read the manual for whatever device you are working with and see what its communication protocol is. They may not expose that information through the serial port. It's even possible that the only thing that identifies the serial number for a particular device is its label stuck to it.

RLS for system identification: problem in creating a signal + noise input.

i have successfully implemented the RLS algorithm in labview, but i am having alot of trouble generating an input. at first i used a ptbypt sine input and wired it to my FIR Filter (win coeff ptbypt) and to my data queue (ptbypt) to generate U(n). When i plot the adjusted weights they give a perfect Sinc Function.
So, after this i add in a gaussian White noise VI (ptbypt) and add it's output with the output of the sine wave VI (ptbypt) and like before wire the output of the summation to the FIR Filter and the data queue point by point. The problem that is occurring is that my tap weights after becoming constant do not change. they are the same for when i enter the sine wave alone and when i enter the sine wave with the gaussina white noise, tap weights are same. they only change when i change the low cutoff of the FIR FIlter.
its would be very much appreciated if someone may help me solve this problem i am having. I made the RLS (for system identification) as Final Year Engineering Project.

the input is a sine wave , the sine wave passes through a system which incorporates a noise in it (we say the noise incorporated by the system is the Gaussian white noise) the corrupted input enters the system , the filter weights are adjusted by the algo, and a sine waveform is extracted filtering the noise.
what kind of LTI system. Can you please elaborate? and i cant switch to LMS my project is RLS.

Universal Entity EJB find/select method for single db table

Hi there.
I'm quite new in bea spheres and my question reflects my small knowledge:
Is there any way to perform "universal" sql query on single database table via find/select methods? This means, that I would like to pass whole WHERE clause to these methods, not just some fields values.
What do I mean?
Normally we define find/select method that looks like this one:
SELECT OBJECT(o) FROM Cities AS o WHERE population>=?1 AND state=?2
We call this a method this way:
finder1 (1000000, 'France')
Method returns collection with objects holding data about cities in France with more than 1000000 inhabitans..
But, I want to define method, that could be called this way:
finder1 ("o.population>=1000000 AND o.state='France'")
This method should be able to perform any query on 'Cities' database table.
I tried with defining find method for following query:
SELECT OBJECT(o) FROM Cities AS o WHERE ?1
but it does not work, of course.
Is there possibility to define method that could be called this way?

DRQ: Specific Identification Method for Inventory Valuation

This is a request to incorporate the features of Specific Identification Method (or Actual Cost) of Inventory Valuation for Serial Number / Batch Number controlled items.
Found lots of threads in the Forum regarding this topic, but could not able find out any answer from SAP.
Sometimes back, myself posted the same thread, but got reply that Navision has this features please use that.
Hope SAP Team has enough knowledge about this method of valuation, that is why I am not giving any example.
If require I can provide enough example on this topic.
Thanks & Regards

Hi Peter,
This is the same requirement we need in mexico. What do you mean with "Next major releases"?
In other words, this requirement is not going to be consider for next version 8.8?

Oracle.jbo.AttrValException: JBO-27019: Get method for attribute

Hi Guys,
I am trying to add a new column to Oracle quoting.It has already been customized by some consultant few years back. I followed the note 392728.1 on metalink and also have the documentation by the previous consultant but getting the error oracle.jbo.AttrValException: JBO-27019: Get method for attribute Draft in HeaderVO could not be resolved after adding my column, when I try to print the quote.
Here are the steps I took
1) added a column to the query (at the end) in HeaderVO.xml
2) added the below code in the HeaderVO.xml
<ViewAttribute
Name="DRAFT"
IsQueriable="false"
IsPersistent="false"
Precision="100"
Type="java.lang.String"
AliasName="DRAFT"
ColumnType="VARCHAR2"
Expression="DRAFT"
SQLType="VARCHAR" >
<DesignTime>
<Attr Name="_DisplaySize" Value="100" />
</DesignTime>
</ViewAttribute>
3). Modify HeaderVORowImpl.java file to add setters and getters for the newly added view attribute. For example,
a) case 67: //
setDRAFT((String)obj);
return;
b) case 67:
return getDRAFT();
c) ublic void setDRAFT(String s)
setAttributeInternal(67, s);
public String getDRAFT()
return (String)getAttributeInternal(67);
d) protected static final int DRAFT = 67;
Everything is dont exactly as per the manual but not sure why I am getting this issue. Any help will be appreciated.

a) case 67: //
setDraft((String)obj);
return;
b) case 67:
return getDraft();
c)public void setDraft(String s){
setAttributeInternal(67, s);
public String getDraft(){
return (String)getAttributeInternal(67);
d) protected static final int DRAFT = 67;
can u change it as explained above.. setDRAFT should be setDraft.. and getDRAFT should be getDraft..
and make sure that the index.. number is exactly matching with the attribute order in the VO

What is the direct connect method for transfering photos from my macbook pro to my iphone without using iTunes syncronization? (iow: a simple photo copy from mac to iphone?)

I feel like I should know the answer to this. I can't believe it is a hard question.
What is the direct connect method for transfering photos from my macbook pro to my iphone without using iTunes syncronization? (iow: a simple photo copy from mac to iphone?)
Easy? Right?
Just plug my iphone in to a mac and copy a photo from the mac to my iphone.
I don't have internet access - I can't email it, or mobileme it, or dropbox it.

iTunes. Other than that there is no direct method. However, do try the iPhone forums.

I already have a valid payment method for my iTunes account, but can't get past the Family Sharing setup prompt telling me to add a payment method . What to do?

I had the same problem and found a bunch of others did, too. Unfortunately all the posts had no responses! Anyway, I previously had my payment method linked to my paypal. I tried changing it to my credit card and it worked. Don't know if there's a bug with using paypal but that seemed to be the culprit for me. Good luck!

Error : FZ010 : Enter a payment method for incoming payments

Hi,
I am running F110 and paying intercompany vendors/customers.
I am running payment run for Compony 0050 and paying my vendor VEND0060 and CUST0060.
The balance of vend0060 is 2 million(credit) and balance of CUST0060 is 1 million (Debit).
So I am going in Reallocate and changing the bank details as getting exceptioin in CUST0060. But it gives out an error "Enter Payment method for incoming payments"
We have just configured outgoing payment and actually as credit balance is more, it should not give this error.
Does any one know solutin for this?
Error in details:
Enter a payment method for incoming payments
Message no. FZ010
Diagnosis
The balance of the items to be paid requires a payment method for incoming payments. You specified a payment method that is defined for outgoing payments.
System Response
The payment method is rejected.
Procedure
Enter a payment method for incoming payments.
Thanks
JR

In the master record of the customer/vendor, ensure that the appropriate payment methods are maintained. If you click on F4 on the payment method field, you can see different methods available for Incoming Payments and different methods for Outgoing payments.
Assign points accordingly.
Thanks,
Madhav Nanduri

Error while scanning for Serial-ATA devices.

There was an error while scanning for Serial-ATA devices. I'm not sure how to trouble shoot this. I believe a secondary drive in bay 2 died.

I also have just began to hit this issue.
I have 4 2T enterprise class WD drives in a raid 1+0 (or was it 0+1) config.
Device Model: WDC WD2002FYPS-01U1B1
One disk (disk0 in bay 2) keeps disappearing. Completely. /dev/disk0 and /dev/rdisk0 vanish.
If I look at "about this mac" / "More Info" / "Serial-ATA" I get the "error while scanning ...".
If I reboot, the offending disc comes back and the raid volumes start rebuilding.
The SMART status is (reported to be) fine.
I use the 'smartmon' tools and look at the extended SMART status and the values of the counters all looks the same as the other drives. I can run an extended offline test, which takes forever to execute. disk 1 and 3 eventually finish with success (it writes this status into a SMART log area on the disc).
Disk 2 and 0 take longer. I image this is because 2 is being read to resilver 0. Currently, I am running with disk0 absent again, and disk 2s test did not complete. It claims it was aborted by the host, so I imagine the one on disk0 will claim the same after I reboot.
My system is under extended AppleCare until 16 Jan 2011, so if I can determine that this is a disc controller error, I can get it fixed. The drives have a 5 year warrantee, and are less than 1yr old, so they are covered. I just need to figure out what the issue is.
I will now reboot and recover disk0 and see if perhaps there is anything recorded in the SMART log.
There is nothing in kernel.log specific to disk0. I include the log extract here for posterity. The "speed" volume is not raid 0+1, just striped, which is why it gets aborted.
