PXI 6514 SCB-100 Help

hi all,
I tried many times to get a Digital Out from that box. But without any success.
I have a board with i need to pull 32 Pionts down to zero. And I have PXI 6514 SCB 100 and PXI 6733 SCB 68.
I made it at the 6733 to bring a signal out of the digital outs, but at the 6514 happens nothing!
Can someone help me???

When i set the switches in the passthrough mode (S6 up, S5 down, S4 down, S1 rigth, s2 right, S3 right) all pins passthrough (Pin1 = Pin1...Pin100=Pin100)
Is that the only way to get all the 32 in/out Ports of the 6514 to the board????
I testet sometimes: for example GND to Pin 96 and 5V+ to Pin 97. Then i measure on Pin 95.
When i put the line 7 of port 7 to low i measure 2Volt and at high i measure 5Volt. That seems to be a bit correctly. 
But should there not be 0V when i set it on LOW???? Or where from could that 2V be?
I dont know, what to do...
can someone help me??? or just give me some info?
best reguards
Simon

  • PXI 6512 to PXI 6511 using SCB-100

    Hi;
    Using LabView 8.6, I want to pass a discrete signal from a PXI 6512 (DO) to a PXI 6511(DI).
    Each of these cards have a SCB-100 connector block. I have set the switches (S1 to S6) of each card to "DIO passthrough" as specified in SCB-100 Installation Guide Figure 3.
    I'm using the following NI examples: Write Dig Chan.vi (running on 6512) and Read Dig Chan-Change Detection (running on 6511)
    1. I have connected the PXI 6512 SCB-100 pin #1 (Port 0 Line 0) to PXI 6511 SCB-100 pin #1 (Port 0 Line 0).
        Result: I does not work; that is:
                                              a) Changing voltage on 6512 is not detected on 6511 vi
                                              b) Changing voltage on 6512 MAX is not detected on 6511 vi
    2. I have a connected both pin #1 to pin #1 and pin # 9 (GRND) to pin #9 (GRND), doing the same as above (1.a and 1.b) , it still does not work.
    3. To make things worse, I put a voltmeter on the SCB-100 pins of 6512, no voltage is generated.
    I wonder:
        - How to connect two SCB-100 connectors for my case? is there something special to do in addition to setting the switches ?
        - How can I be sure using MAX that my cards are OK?
        -  What are the correct driver versions (is it "traditional DAQ driver"?) for my cards?
    Thank you in advance for the replies;
    Kizkas.

    Hello KizKas,
    When performing the write to the digital channel, have you tested other lines other that Port 0 Line 0?  Have you tried using a different breakout box, or a different cable?  Have you double-checked all of your connections? If you could try all of these steps and measure the voltage on the line using a voltmeter you should get more information on what is wrong with your system.
    The only steps you can perform in Measurement and Automation Explorer (MAX) to check to see if everything is working with your system is to first check to make sure that the icon next to your device under My System»Devices and Interfaces»NI-DAQmx Devices is green.
    Figure 1: Green is Good
    You can also attempt to reset the device or perform a self-test on the device itself by clicking on the device and clicking on the appropriate buttons.
    Figure 2: Self-Test and Reset Device
    For these devices the correct driver to use would be NI-DAQmx 8.8.

  • Connecting the SCB-100 to a Solid State Relay

    Hey everyone,
    I am trying to hook up a solid state relay to the SCB-100 which is connected to a PXI 6515 device. I was just wondering where I can purchase the connecting wire that is ideal for this purpose. A quick look online has yielded few helpful results. A link to grainger/zoro tools or others would be appreciated. The specifications are: The wire must be able to withstand 25V voltage, 25A current. It should also be easy to wire it into the SCB-100. Any AWG will do. 
    Thanks!

    Hi tompkins92,
    Here is some information about AWG cables and their maximum current:
    http://diyaudioprojects.com/Technical/American-Wir​e-Gauge/
    Here is a place you might be able to purchase the appropriate wire:
     http://www.mouser.com/Wire-Cable/Hook-up-Wire/_/N-​5ggs
    You can select the voltage and current specifications you want.
    I have one question: did you mean 25 mA current? Neither the SCB-100 nor the PXI 6515 can safely handle 25  amps.

  • Why is AIGND on SCB-100 connected to mains earth through PCI6031E?

    I have a PCI-6031E DAC card connected to an SCB-100.  I am trying to measure non-referenced differential signals, and via the application notes realise that i must use two bias resistors to AIGND from the +ve and -ve terminals of each channel.
    However i can't quite understand why the AIGND pin inside the SCB-100 is connected to mains earth through the DAC card.   Surely any disturbances on the earth due to the operation/swiitching of other equipment on our site will produce disturbances on the reference of the DAC card, and hence effect the data that i am recording?
    Or is this connection not direct, i.e through a resistor for example?
    Any guidance would be much appreciated.
    Many thanks
    Mike

    Hi,
      the resistors are both tied to the same point, ergo any change in voltage on the earth line will appear on both signal lines (aix+ and aix-).
    Since this is a differential input, they will be cancelled out as a common mode voltage.
    The purpose of the resistors is to prevent the input voltages to the aix+ and aix- floating off. You're measuring a differential voltage, say 10V, but that could be at 50V on the aix- and 60V on the aix+. That would damage the card, and without the resistors, the signals from a true floating source could continuously float up and down.
    You're quite correct in the fact that aignd is also pc or system earth, and you can get mains earth signals on this pin, hence the reason we recommend NRSE or differential as the better two input types.

  • "connecting a load cell to scb-100"

    I have an scb-100 and want to know if it is possible to connect a load cell to it and if so, how.

    It is probably possible, but you have to have some additional circuitry in order to use the load cell. Typically, load cells are comprised of strain gauges which require some kind of Wheatstone bridge completion. Additionally, most strain gauges need excitation. If you can provide the bridge completion and excitation, then you could simply read the output of the strain gauge by connecting the output + and - to your SCB-100. However, setting up this external circuitry can be a little complicated. So, the recommended setup is to use some signal conditioning. National Instruments provides a couple of options regarding signal conditioning for load cells. Below is a link to a tutorial that discusses how to measure a load cell and what hardware is recommended for
    that. I hope this information helps.

  • Make a signal active or inactive for PXI-6514

      Hello,
      I have NI PXI 6514 Digital I/O device and let's say that I want to change the Signal P4.0 to inactive by sending + 3V or inactive by   having high-impedance value. My question is how I can write to this digital line this 3V using the Write Dig Chan. vi.
    Thanks in advance,
    Iliya 

    Hi,
    the output voltage on PXI-6514 digital line is directly connected to VCC by a Darlington driver. Please see the link below.
    http://digital.ni.com/public.nsf/allkb/8D46388A20C​5A23E862572B8007E8C82?OpenDocument
    Due to the diode in place, the output impedance measured between the positive and ground terminals is very high whether the switch (Darlington Driver) is open or closed.
    You could send more details about your requirements.

  • CJC Temperature sensor measurement on SCB-100

    I am trying to measure temperature at CJC-T sensor on SCB-100 box. I grounded the differential channel "0" (short-circuited pins 2,3 and 4). I am measuring a temperature reading(22.3 Deg Cel) at channel "0" (I am not sure if it correct) when CJC was disabled (S4 and S5 in down position) but some junk when I have the CJC enabled(S4 and S5 in up position). Moreover, it shows the same reading even when the SCB-100 box is put in a heated chamber. why?
    I have similar problems with an external thermocouple too. Ironically, it reads when CJC is disabled and nothing when CJC is enabled. Am I missing something that needs to be done? I am also attaching the SCB-100 manual for quick reference.

    Also, make sure that you have selected the scb-100 as the accessory for the DAQ board. You can do this by right-clicking on the DAQ board under devices and interfaces in Measurement and Automation Explorer (MAX) and selecting "Properties," going to the Accessory tab, and then choosing the scb-100 (check the CJC jumper set). Once you do this, you can create virtual channels in MAX and will want to select "built-in" for the CJC of the thermocouple virtual channel.

  • What is the pin out connections of SCB 100

    What is the pin out connections of SCB 100

    Suresh,
    Since the SCB-100 is a terminal block, its pin out is dictated by the DAQ device to which it is cabled. Thus, the pin out is available in the user manual for the appropriate DAQ device. Below, I have included a link to the location where the user manuals are available:
    Manuals
    Good luck with your application.

  • Keithley 6514 and 6220 help!

    hey guys help a newbie out,
    ive got a keithley 6220 current source and a 6514 electrometer.  Im trying to get a simple I-V plot. I am having the hardest time trying to program labview.  Ive downloaded the drivers for the 6514, im just programming the 6514 now and triggering the 6220 manually. I want labview to basically be able to read the voltage values and plot it vs. time. 
    labview can communicate with the 6514 as the REM indicator is on.  I keep getting a general I/O error, and i cant figure out what it is. 
    Help!!

    I looked at your VI (and downloaded the Keithley drivers). I do not have the instruments so I cannot actually test it. One thing is immediately obvious: All the Keithley VIs require a GPIB address. I cleaned up your VI a bit and wired one Address control to all of the VIs which needed it. I also added an error out indicator so that you can see what error is occurring and where.
    My experience with Keithley GPIB Vis has been that they are useful in that they contain the code for most commands but their style and performance leave a lot to be desired. My guess is that they were wrtten about ten years ago and the only updates since then have been to recompile with newer versions. I am rewriting all the VIs I need for other Keithley instruments.
    I do not like inputs on the right and outputs on the left. If I have more than 4 (or maybe 5-6) inputs or outputs on a single VI, I try to rethink what I am doing and either cluster some of them or break things up.
    Another thing to try is to use the simple LabVIEW <-> GPIB.vi in the examples folder to make sure you can communicate with the instrument. Start out by doing an ID query or status and see if you get back the answer specified in the manual. Once you can communicate, then look at the first driver VI which produces an error and see if you can send the commands from the LV <> GPIB manually until you locate and eliminate the problems. GPIB is usually cleaner than RS232, but it can still take quite a bit of detective work and patience to get everything working the way you want it.

  • Gostaria de obter a documentação da pinagem do Bloco de Conexão SCB-100

    Question in Portuguese

    Olá Henrique, tudo bem?
    Na verdade em nosso processo é exatamente isso: a NF de Importação é feita de maneira Writer (pois ela ocorre antes da recepção da mercadoria) e na entrada de fatura, não geramos a MIRO com a Categoria de NF, ou seja, apenas é feito o registro do documento de faturamento para gerar o Contas-a-pagar para o controle do Departamento Financeiro.
    No nosso caso, optamos por utilizar transações Z (uma para que o Departamento de Suprimentos alimente as informações necessárias da DI com base no Pedido de Compra/Item registrados E outra para o Departamento Fiscal ligar as informações do Pedido/Item gerado por Suprimentos contra o Número de Documento Fiscal/Item criados da NF Writer). Depois, o Departamento Fiscal utiliza o processo "standard" SAP para a geração da NF-e de Importação (Desembaraço), através da "Determinação da NF-e" na transação do Monitor.
    Por trás do sistema o que fizemos foi exatamente utilizar a BADI CL_NFE_PRINT, método FILL_ITEM, e conseguimos recuperar os dados de Importação e então mapeá-las nos campos necessários.
    Não é lá a solução que eu imaginava (pois eu imaginava ser possível utilizar aquela aba Importação lá do Pedido de Compra, módulo SD-FT-PRO - Foreign Trade) mas funcionou no teste integrado e já está no ambiente de Produção, bem como a solução da NF-e 2.0, esta que implementamos "internamente", com as maiores complicações mesmo na parte do PI, uma vez que não temos especialistas aqui e eu acabei tendo que mergulhar na nota SAP e fazer acontecer!
    Abraço e obrigado por seu "feedback"!

  • DDTS-100 Help

    I was just wondering if there is a way to adjust the volume of the left and right speaker individually? I've tried using the method in the manual and it doesn't seem to work. It seems to only change the volume of all the speakers. I do not have the DDTS hooked up to a a computer so I cannot adjust the settings on the sound card, and then output them out to the DDTS.
    Thanks

    nope, why would you want it anyway?

  • DDTS-100 - HELP PLEASE!

    ] Hello,
    I acquired a used DDTS-00 (discontinued) from Singapore.
    It says on the AC adapter:
    INPUT: 230V? ~ 50hz 00mA
    OUTPUT: 6V ~ 600mA
    Can I use this device here in the US with just a simple socket adapter (since the voltage is less here in the US) ? Or do I need a step-up transformer?
    Thank you.

    You do realize this product has been discontinued, it's?bundled?accessories like power adapter, etc are no?longer?available through Creative. Yes, if you can find an adapter?with the same output that?should work or?check with your local electronics store for a step-up transformer. ?

  • Dropped my iPhone 5S in water, I think it's safe but I'm not 100%, HELP

    I dropped my iPhone 5S in the bath for around three seconds, I grabbed it and dryed it off and it seemed to be working normally. I used COOL air to gently dry out the charging and headphone jack just to be safe. About twenty minutes later my phone did not have service in my room and it was charging inconsistently. My phone has never not had service in my room over the last 3 months I've had it. I read a few articles online and immediately turned it off and put it in rice. I checked the water damage indicator around two hours after it had been in the rice and it was not red so I just wanted to know if this meant my iPhone does not have water damage and I'm safe? I still have it in the rice just to be safe.
    Thanks!! 

    No, it means it is working for now. That is no guarantee that it  will not fail tomorrow or next week. Your chances of an eventual failure just went up.
