OptiTracker-PC™
Quadrature Encoder Interface for Closed Loop Positioning

FEATURES: 1.3 MHz max input frequency 24 bit presettable counters General purpose 8 input port Accurately start & stop signal reception User selectable ×1, ×2, ×3, ×4 multiplier Includes a DRO program with C source Accepts inputs from either incremental or quadrature encoders (user selectable) Easy to use software is compatible with C and QuickBASIC

The OptiTracker is a high speed 1, 2, 3, or 4 axis quadrature encoder interface. Designed for standard IBM-PC/XT/AT or compatibles. The maximum speed is a respectable 1.3 MHz in either quadrature or count modes. In quadrature mode the inputs are the A and B (90 degrees out of phase) signals from the encoder, and in count mode the inputs are the step and direction signals. The counters will track absolute counts to ±8,388,607. The index pulse can be read from the input port. Eight TTL compatible inputs are available for general application.
