Product Short Description
Product Name: 3U MACRO CPU Board (MACRO-CPU), part of UMAC MACRO / MACRO Stack
Product Introduction: The 602804-109 (belongs to the 3A0-602804-10x family) is the processor and MACRO ring interface board at the heart of Delta Tau’s 3U MACRO Station. It executes motion-control firmware and communicates with PMAC2 Ultralite or Turbo PMAC2 Ultralite masters via the electrically isolated MACRO ring, providing remote access to encoders, flags, PWM/analogue/stepper drives and digital I/O.
