i have a AX-12A. I found the manual at https://emanual.robotis.com/docs/en/dxl/ax/ax-12a/ an saw the diagram in chapter 5.4.2, but I don’t understand it.
- which side is RS485 and which side is TTL to AX-12A? I assume, right is AX-12A?
- I assume, the “MOLEX4P” represents the molex connector at the AX-12A. But on my AX-12A, I have only three pins. So, how it is wired actually?
- what does “TTL Level Multi Drop Bus” mean electrically? Is that open collector? Or what?
- Is “high” logically “true” or “false”?
Maybe someone has answers to my questions.
