Tamagawa Absolute Encoder interface

[paubine]

Hi,

I try to interface a Tamagawa TS5669N124 absolute encoder that come with Allen Bradly motor. (attached datasheet).

There is only data+, data-, ground, 5v+. So it's not SSI Encoder (no clock+-), it's not enDAT they call that "Absolute A"...

I have to catch all pulses for this encoder on the FPGA side. I have a differential input (9411) available for this.

Anyone know where to begin with that?

Thank you,

Patrick
