Reading 12-Bit Absolute-Encoder

Hi guys,

I'm trying to get data from an Singleturn absolute encoder 12 bit with Arduino Uno.
Datasheet: https://www.faulhaber.com/fileadmin/Import/Media/EN_AES-4096L_DFF.pdf

I read and tried the Code in Absolute rotary Encoder SSI SPI how ? - Networking, Protocols, and Devices - Arduino Forum but it did not work.

should I connect all the pins (CLK+, CLK-, DATA+, DATA-)? If yes, how can I connect these to Arduino Uno and what should the code look like?
I mean, how can I get the result from these 4 pins.
After googling for an answer, I read that I may use "single ended". Can anyone explain this please.

I'm sry for the many questions, but I'm not really familiar with these topics.

Use a 2 channel RS422 converter to convert the encoder signals into TTL levels so that they can be read by the Arduino.
Find or make a library that knows how to decode SSI/BISS-C signals.
