The Mx4000MB (Mx4 Multibus) is a 4-axis, Multibus motion controller, which complies with all multibus 1 signal timing standards. The Mx4 is powered by a multi-DSP parallel processing architecture. It contains several DB connectors for interfacing to encoders, servo amplifiers and I/0s in CNC and other factory automation applications.

Its programming support includes DLLs for C, C++, and Visual Basic. This card can also be programmed by DSPL, a C-like language resident in Mx4. Using the Mx4 processing power, the Mx4 performs computer, PLC, and motion controller functions in motion computer control automation applications.
