Shall I use NRSE or RSE mode for reading the output voltage of my sensor?

Hello,
I am using a gaz sensor that needs a power supply of 24 V and has an output voltage : 0 -> 10 V. I want to read this voltage with labview( and then convert it to PPMs ).
My problem : I don't know what kind of analog input connection I must use : RSE ou NRSE ? ( I suppose the DIFF mode isn't appriopriate here ) .
I think I should use the NRSE mode ( meaning connecting the V+ of the 0-10V signal to one of the ACH and the V- to AISENSE ) ???
Any help would be really great,
Regards,
David
PS : using Labview 7.1

Hi David,
It basically all boils down to if the signal source is grounded or floating? If grounded use DIFF for low voltages (0-2V) and NRSE for high (above 2V). If the signal is floating use RSE.

HT5878 how to check the detail of font being used for reading the file received by an email

I received word file as an attachment with email on my iphone. I want to check the detail on font being used for reading the word file received as attachment in an email.
Thanks

You don't need to copy the cert out of your configuration. OpenSSL has an "s_client" subcommand which can open an SSL connection and verify the cert for you. It even knows how to do STARTTLS. Something like this ought to do it:
openssl s_client -starttls smtp -CAfile /path/to/ca/file -connect your.ironport:25
The /path/to/ca/file is necessary to provide openssl with a cache of root CA certs. You could use -CApath instead of -CAfile if you have a hashed directory of root CA certs instead of a single file containing them all.
You can also point this at your partner's SMTP server as well.

Print program for the smartform for selecting the output type (email/fax)

Hi All,
Requirement :I have to create a print program for the smartform where the output type may be print out,email or fax ,so i need to put the condition for selecting the output type (like printout,email,fax).
can any body please let me know how to put the condition for selecting the desired output type ?
Thanks in advance
Rahul

Hi
It is not the output type that has to be changed
it is the MEDIUM which you have to change and configure
for printout medium is 1
for FAX medium is 2
for MAIL it is 7.
so instead of printout change the medium to 2 or 7 for the same output type and attach to the same driver program and smartform/form.

Hi,
greetings to all!! I have a problem here guys-I need to find any exit or badi for enhancing the output of the tcode S_ALR_87013532.This tcode is used for seeing the planned/actual/variance of project cost.
In the output we have got 3 columns-total of years, previous years and 2009. Under each column we have Plan, Actual, Variance and VAR %. Our requirement is to show Functional Location(PRPS-TPLNR), Budget Number(TCN01-SWRT0), SBU (TCN01-SWRT1) and Region (TCN01-SWRT2) in each of the clolumns-you can also get the last 3 fields in PRPS table as USR00, USR01 and USR02.
Can anyone help please?could not find anything worthwhile on SDN. Thnx a lot !

RSE, NRSE, or DIFF mode for my application?

Hello,
I am using a pressure sensor that needs 5V supply and generates a 0->2.5V output. I would like to read this voltage using Labview. However I am not sure which mode( diff, RSE, or NRSE) I should use here. I have attached a very simple photo of the way to connecte the sensor ( delivered with the sensor). There is :        1 supply connexion
             1 Ground connexion
              1 AGround connexion
               1 Vout connexion
I have already tried :
RSE mode : connecting to ACH and AIGND. I see a 1 to 2mV offset ( compared to a LEM). But I thought this wasn't appropriate in my situation?
NRSE mode : connecting ACH and AISense. Offset <1.5mV
( I haven't tried with any resistance )
Since the way of connecting this sensor is very common ( I will probably use this way of connecting again), could anybody tell me what the correct mode is? I have already read answers on the forum and the NI application note about how to use those different modes, but I haven't been able to conclude....
Any kind of help would be great!
Thanks,
Toto

Bonjour,
Le problème d'offset peut-être lié à plusieurs paramètres qu'il faut chercher à isoler.
Quelle est la différence entre le GND et le AGND sur votre capteur? Comment alimentez-vous ce capteur, via le +5V de la carte d'acquisition? Comment calculez-vous cet offset? Avez-vous essayé de connecter des résistances de biais sur les entrées de la carte?
La note d'application suivante récapitule bier les différents modes de connectique.

Anyone using M-Audio FireWire Solo for iChat audio output?

Audio output for iChat works perfectly through my G5 internal speaker but does not work through my FireWire Solo. It yields 100% digital distortion everytime the person on the other end speaks. Everything else in my setup works beautifully with my M-Audio device (Logic, Pro Tools, Reason, iTunes and all other applications).

You have landed in iSight Discussions. You may find better help in the Expanding your Power Mac G5 Discussions or iChat AV 3 Discussions area.
I do not use M-Audio or any of the other things you post about except iChat AV, and iChat AV does NOT work through my DP G5's internal speaker.
I offer the following possibilities for your consideration if you cannot find better help:
(0) When using iSight or iChat AV, you may be experiencing Possible hardware or software conflicts. This link gives tips for investigating that possibility.
(1) You may be trying to use M-Audio FireWire Solo for other than its intended purpose. The web site states, in part: The FireWire Solo is designed from the ground up as an easy-to-use, high-quality interface for songwriters to record guitars, vocals and more on the computer.Perhaps your M-Audio's documentation or the "Support" information linked on the web site can help you determine whether your device is compatible with iChat AV and your other AV equipment.

How Can I configure the 6024E board for reading the voltage from a source?

Hi, I have a little problem, I want to use the 6024E board for reading voltage from a source and then display this on the monitor, and also I want to change the voltage from the output using the computer. I read the manual but I don't understand how to connect and configure the board. It is to proof that the board receive and send information.
Thanks, sorry for my english, I'm from Mexico, if you don't understand something about my explanation tell me.

Thank you, now I'm trying to do my project and I have another question, there are differents ways to connect the source and I choose the NRSE configuration because I'm going to use a grounded signal source... well in the manual says "The signal is then connected to the positive input of the PGIA, and the signal local ground reference is conenected to the negative input ot the PGIA. The ground point of the signal should, therefore, be connected to the AISENSE pin." I don't understand this because I only have two wires and here is talking about three connections, please help me, how do I connect the source to the board? I have the positive wire and the negative wire.... maybe is because I don't have a perfect english and I don't understand the sentence...

Measuring the output voltage from a laser detector(photodiode-TSL 250) using PCI-6014?

i am using a photodetector (TSL-250) to detect the different intensity of the laser beam, since the laser beam is passing throught a different depthness of liquid dye. I am measuring the output in voltage form. is there any measurement studio - Visual basic example illustrate this kind of measurement? thanks

Sounds like this is a simple continuous analog input application. Here are some starting points for example code based on which environment you have. Note: the PCI-6014 is supported by both NI-DAQmx (7.1 only) and Traditional NI-DAQ (7.1 and earlier).

Try these 3 possible solutions:
1. Restart iPad
Hold down the Sleep/Wake button until the red slider appears. Slide your finger across the slider to turn off iPad. To turn iPad back on, hold down the Sleep/Wake until the Apple logo appears.
2. Close inactive Apps
Double-click the Home button; hold Apps down (in the Task Bar) for a second or two until you see the minus sign. Tap and close all inactive Apps.
3. Reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Ignore the red slider.

User exist for controlling the OutPut type in sales order

Hi
Is their any exist which controls the output type based on header data of the order? VA01/02.
Best regards
Satish Kumar K

Hi,
IN the VOFM routine you can use the structure KOMKBV1 which will be populated with the sales org (VKORG), division (SPART) and order type (AUART).
Example
SY-SUBRC = 4.
IF KOMKBV1-VKORG = '0001' AND
KOMKBV1-SPART = '12' AND
KOMKBV1-AUART = 'ZXXX'.
SET THE return code to 0 to propose the output type.
SY-SUBRC = 0.
ENDIF.
Hope this helps..
Thanks,
Naren
