# DASSpecific Constants Module Documentation

## 1. Purpose

This module provides hardware-specific constant definitions and feature-support checks for various Data Acquisition Systems (DAS) in the DTS product line. It centralizes protocol version requirements, hardware capabilities (e.g., maximum anti-aliasing filter rates), and recording/streaming/clock synchronization mode support logic for each DAS model (e.g., SLICE, SLICE6, TSRAIR, PowerPRO). These constants and methods enable higher-level system components to dynamically adapt behavior based on the detected DAS model and its firmware protocol version, ensuring correct operation across a heterogeneous fleet of devices.
