- Position and velocity feedback systems
- Industrial process automation
- Robotics and CNC machinery
- Optical‑mechanical position monitoring

Compatibility:
- PCI 2.1 compliant 32‑bit bus
- Supported OS: MS‑DOS, Windows 95
- Compatible with ADLINK terminal boards (ACLD‑9137, ACLD‑9188)

Signal Processing:
- Differential encoder inputs converted to single‑ended via isolation amplifiers.
- Three‑stage digital filters remove noise spikes.
- Quadrature decoder multiplies resolution × 4.
- Position counters latch data synchronously with index pulses.
- PWM outputs synchronized with INT0 timer for deterministic timing.
