Issue Details

I'm trying to wire my encoder to my NI-9411, but I'm not sure of the pinout. I'm also wanting to power the encoder through the power pins in the D-Sub. How do I wire the encoder to the module?

Solution


Depending on the type of encoder you're using, there are two options of connections to the module. 
  • Differential Encoder (two wires per channel): 
  • Single Ended Encoder (one wire per channel):

For some encoders the wiring will be different to the 9411 module. Some encoders will require an alternative wiring:
  • Pin 1 (PFI0) - A Phase
  • Pin 2 (PFI1) - Z Phase
  • Pin 3 (PFI2) - B Phase

Additional Information

To power the encoder using the 5V pins on the NI-9411 module, you have to plug in an external power supply to the Vsupp and COM terminals on the NI-9411.
