how many port and line per port in PXI 6512

 

i need the info to configure and digital an output signal

 

DAQmxWriteDigitalLines

 

Thanks

got it in the datasheet

 

questions to ask

 

what is the function of the VCC at 50 and 100pins

 

how to generate a voltage from the same banks of ports

Hello there,

 

There are 8 ports with 8 lines each.  The VCC provides a constant +5V as a voltage source/reference for external circuitry. You can find examples using the NI Example Finder in LabVIEW and navigating to Hardware Input and Output->DAQmx->Digital Generation->Write Dig Channel.vi.  If you are programming using a text-based language, please refer to the examples by navigating to Windows Start->All Programs->National Instruments->NI-DAQ->Text-Based Code Support.

thanks for the reply

 

i am still blur for the configuration

 

what does vcc,comm and gnd means

 

do we need to input >5v to vcc to get a output com of 5v ?

 

how this really works.

 

what will be the connection

 

i just want to get output voltage frm the 64 pins

Hello there,

 

More information can be found in the NI 651x User Manual (http://www.ni.com/pdf/manuals/372172b.pdf).  Since you are using a sourcing digital output card, the VCC lines should be connected to your voltage source (+5V ~ +30V).  Please refer to Figure 4-5, NI 6512 Output Signal Connection Example on page 4-6.  You can also use pins 50 or 100 to supply the VCC voltage of +5V.  COM(GND) should be connected to the negative terminal or relative ground of your source.  Once this setup is connected, asserting or disserting the digital lines will provide either a grounded or VCC voltage.
