### 4. Functionality

The LPCIe‑8124‑C functions as a high‑precision encoder counter and trigger generator for motion control and inspection systems. It receives differential quadrature encoder signals (A, B, Z) from motion axes or linear scales, counts position data, and generates synchronized trigger pulses based on programmable position comparisons.

Supported Encoder Modes:
- OUT/DIR (Single Pulse Mode): EA counts pulses, EB defines direction.
- CW/CCW (Dual Pulse Mode): EA counts up (CW), EB counts down (CCW).
- A/B Phase Mode: 1×, 2×, 4× decoding for incremental encoders.

Triggering Functions:
- Position Comparison: Generates trigger when encoder count equals preset comparator value.
- FIFO Mode: Sequentially compares up to 1,023 preset positions for continuous triggering.
- Linear Mode: Automatically increments comparison points by fixed intervals for periodic triggers.
- Manual Trigger: Software‑initiated pulse generation.
- Timer‑Based Trigger: Uses internal timers or external TTL inputs for time‑based pulse output.

Applications:
- Automated Optical Inspection (AOI)
- Line‑scan camera synchronization
- Precision distance measurement
- Motion‑synchronized image capture
- Semiconductor inspection and metrology
- Industrial automation and robotics
