FPGA case structure

[SASA1]

Hi GerdW,

  it's the First time i used the NI 9401 module, i had compiled and run the code on the RT side, but reived nothing on the output of the module.

  in the module what is the need for the com pins (i know they are grounds) , is each DIO have it's com pins?

  and when we use the DIO pins, can we connect all the com pins to the ground of the compact rio.

 Regards,

SASA

Hi SASA,

see the manual of the 9401 module: page 10 and 18.

HiGerdW,

   so COMs are Overvoltage protection and they are not necessary when we use only DIO 0 , 1 , 2 , 3 as output.
