GDM or GDS encoder on ctrlX I/O

I am looking how to read a GDM encoder into a ctrlX System.

To start. There is limited or No info available on this moment. If I look in the documentation I only find the ctrlX I/O Encoder module XI614001 1-channel, SSI Interface

But I need the XI612001 ctrlX encoder interface because I think I need the SIN COS variant. Not the XI614001 which is for SSI.

So Q1 : Can I connect and read-in the encoder values os a GDM as sin/cos encoder in this particular I/O module?

Then Q2: While a GDM is a multi-turn encoder. Does the module XI612001 allows me to use the multi-turn encoder function of the GDM, or will it de-valuate to a single turn sin/cos encoder?
