TRelectronic CEV58 SSI Encoder: Correct Clock Signal Specs for Arduino Interface?

Hi,

Im trying to verify some SSI encoders,  Specifically  TRelectronics Absolute-Encoder CEV58- SSI

I am currently using an arduino board to supply a 5v, 100Khz clock signal.  When I power the encoder up, my data + pin goes high, but will not trigger any data when I move the encoder shaft.

 

My main question-  Is the clock signal Im using correct- or is that the issue.  The spec sheet only says "clock input- Optocoupler". 

There really doesnt seem to be anything else I could have messed up here.  Open to any info.

 

Thanks

 

I figured out my mistake.. My frequency generator signal would not work for the clock, and my initial trial with the arduino I had the hz wrong.

Thanks anyway!
