The DMC-3425 supports Galil’s Distributed Control System. This allows up to 4 DMC-3425s to be connected together as a single virtual 8-axis controller. In this system, one of the controllers is designated as the master. The master can receive commands from the host computer that apply to all of the axes in the system.

A simple way to view Local and Global Operation: When the host communicates with a slave controller, it considers the slave as a 2-axis controller. When the host communicates with a master, it considers the master as a multi-axis controller. Similarly, an application program residing in a slave controller deals only with 2 motors as A & B. An application program in a master deals with all motors referenced as A through H.
