DIRXOR(OPCSDEFS) Optical Printer Control System DIRXOR(OPCSDEFS) NAME dirxor - invert direction of motor; direction "exclusive or" (XOR) SYNOPSIS dirxor [chan] [invert] EXAMPLE dirxor b 1 # invert direction of the projector motor. dirxor c 1 # invert direction of the camera motor. DESCRIPTION After setting up a new motor, you notice that executing a command that should run the motor forward actually runs it BACKWARDS, and vice- versa. You can remedy this by either rewiring the motor (the hard way), or changing the DIRXOR(OPCSDEFS) command in your OPCSDEFS.OPC file. By changing the [invert] value from 0 to 1 (or 1 to 0, as the case may be) you can invert the software's sense of direction for that motor. [chan] is the motor channel being affected. [invert] can be either a 0 (default) or a 1, depending on which value suits the installation. BUGS None. ORIGIN Gregory Ercolano, Los Feliz California 11/29/89
