OptiStep Plus-PC™
Motion Control Card For PC/AT, 1-4 axes

FEATURES: Cost effective, field proven design Total interactivity with the user Easy to use software Occupies a single slot Does not require a device driver Does not tie up a parallel or serial port Provides coordinated control of up to 4 axes Programmable acceleration / deceleration Provides complete electrical isolation between computer and driver Synchronizes to external pulse source to accommodate Wire EDM, Lathe threading, & electronic gearing Available with feedrate override and potentiometer

The OptiStep Plus-PC is a high performance motion control card for IBM PC/AT computers that operates up to 4 axes. The control lines are optically isolated and provide step and direction signals for every axis as well as two current control lines that allow the selection of four current levels. The OptiStep Plus controller can be used in conjunction with any of our stepper motor drivers or with any third party driver product that accepts industry standard step and direction commands.

SOFTWARE:

Several software options are available. Any one software package will operate on its own. (i.e. you do not need one package to run another). The software you choose depends on your application. The software options are as follows: 1)MillMaster Pro^tm; 2)TurnMaster Pro^tm ; 3)SuperScribe^tm; or 4)InStep^tm. InStep^tm provides the most flexibility but requires some computer programming knowledge, while the other packages are more machinist oriented.

REQUIREMENTS:

• 8 or 16 bit IBM PC / AT expansion slot
• 5 to 7 volts DC external power supply (to power opto-isolation circuit capable of at least 450mA)
