Optical Encoders output

Hi all,

I am working on a preliminary project: retrofit of a large CNC router for wood.

the drivers are Yaskawa servopack CACR-SR20BE12G-E

CACR_ServoPack

It apparantly has incremental encoders from motor to drives, but out of drives to connect to linuxcnc are optical line drivers I believe.
PA0/*PA0
PB0/*PB0
PC0/*PC0

IS there a card that cann accept these type of signals for encoder inputs? Would rather go with mesa cards if exist.

Thanks,

Bob

These are standard differential quadrature outputs and will
work with any interface card that accepts differential encoder signals
