STEPPER-200 is a plug-in, 2-axis, command-based stepper motor controller board for the IBM PC/XT/AT and compatibles. It also can be used in pulse-type servo motor control (pulse input type). This board has an μP build-in . ThisμP perform variety of motion control commands itself and share the loading of host computer . A 2Kbytes-FIFO is introduced as a command buffer. This buffer can provide 1360ms buffer time. Therefore the hardware architecture of STEP 200 is good for windows operation system. The STEP 200 will provide DOS, Windows 95 and Windows NT driver. It can offer real time motion control solution in windows system.
