How do i wire the NI 9422 to an Encoder?

[RhannaSG]

HI

I want to connect the NI9422 to an Encoder. 

The encoder data sheet is :

http://mdm.kpno.noao.edu/td/PDFs/BEI/H25_Incremental_Encoder.pdf

Looking forward to some help on this matter. 

Im using cRIO 9024   and My encoder is BEI H25D-SS-512-ABC-7830-LED-EM16-S

Pinouts for encoder are:

A >  A
B>   B

C>   A-
D> +5V

E>  B-
F> 0V

G> Case ground.

Thank you.

hi,

I think you should be using 9411(http://sine.ni.com/nips/cds/view/p/lang/en/nid/208812) module since that has differential digital input.Looks like you have the wrong module to use. Your incremental encoder has A+, A- and B+, B- which requires differential inputs. 9422 is a 8 channel digital input module for 24V to 60V logic level input, which does not meet your requirements and it is also not differential input.

If you have the correct module, then maybe you can visit this page to find out more?
