ICM-1100 Interconnect Module
The ICM-1100 Interconnect Module provides easy connections between the DMC-1000 series
controllers and other system elements, such as amplifiers, encoders, and external switches. The ICM-
1100 accepts each DMC-1000 ribbon cable (for J2, J3, J4 and J5) and breaks them into screw-type
terminals. Each screw terminal is labeled for quick connection of system elements.
