### 4. Functionality

Purpose:
NDS-DLL6 acts as a middleware layer between user applications and NuDAM hardware modules. It provides a standardized API for performing analog input/output, digital I/O, counter/timer operations, and configuration management.

Operation:
Applications communicate with NuDAM modules through the DLL using RS-232 serial commands. The DLL handles low-level communication, data formatting, and error checking, allowing developers to focus on application logic.

Use Cases:
- Industrial automation and process control
- Laboratory data acquisition
- Environmental monitoring systems
- Remote sensing and telemetry
- Machine control and diagnostics

Compatibility:
- Works with any Windows programming environment supporting DLL calls.
- Compatible with ADLINK’s NuDAM 6000 series hardware modules.
