My DAQ and absolute encoder

My DAQ and absolute encoder

i wanna read absolute encoder 12bit pepperl-fuchs by My DaQ, but i don't see clock signal from encoder on oscilloscope NI ELVISmx. I connect wire data+ with port AO of board MyDaQ. My encoder was die or My way was wrong?????..Please help me

(datasheet in page 56)

Re: My DAQ and absolute encoder

Hi theAntu:

 

     I would check some more basic stuff with the myDAQ before considering that something is wrong with it. 

 

     I would open NI MAX and try to read some known signals (like for instance using a function generator) or just reading noise and confirming that this is successful.

Re: My DAQ and absolute encoder

in datasheet of absolute encoder (picture). it must have rs422 standard to read data from the encoder, do you know how to use rs422 standard? plz help me

Re: My DAQ and absolute encoder

422 is serial communication (just as USB, ethernet). When used in LabVIEW (where I have more experience) that requires the driver NI VISA. You can then perform either basic queries in NI MAX or code in LabVIEW with the VISA functions.
