# Documentation: Configuration Class

## 1. Purpose

The `Configuration` class is responsible for configuring Data Acquisition System (DAS) hardware devices by applying voltage threshold settings, resetting hardware lines, and persisting configuration files. It serves as a bridge between test templates and physical DAS hardware, ensuring devices are properly configured for either diagnostic or armed operational modes. The class handles the complete configuration lifecycle including threshold application, hardware line reset, configuration upload, and local file backup.

## 2. Public Interface

### `Configuration()` (Constructor)
**Signature:** `public Configuration()`

Default parameterless constructor. Performs no initialization.

---

### `SetConfig`
**Signature:**
```csharp
public void SetConfig(
    DataModel.TestTemplate currentTest,
    List<IDASCommunication> dasList,
    bool calledDuringDiagnostics,
    StatusHelpers.SetProgressValueDelegate setProgressFunction)
```

**Behavior:** Configures all DAS devices in `dasList` with voltage thresholds and hardware settings. The method:
1. Acquires a lock on `DASHardware.GetArmStatusLock`
2. Sets minimum/maximum valid input and battery voltage thresholds for each DAS
3. Applies either diagnostic or armed voltage thresholds based on `calledDuringDiagnostics` parameter
4. Resets hardware lines via `ConfigurationService.ResetHardwareLines`
5. Calls `ConfigurationService.SetConfiguration` with multiple parameters including AAF rates and DSP settings
6. Copies configuration files to the test directory via `CopyGlobalConfigsToLocalFolder`

---

### `ErrorCallback`
**Signature:**
```csharp
public static DialogResult ErrorCallback(string errorString, string units)
```

**Behavior:** Static callback method that logs configuration errors via `APILogger.Log` and returns `DialogResult.OK`. The `units` parameter is not used in the implementation.

---

### `CopyGlobalConfigsToLocalFolder` (Private)
**Signature:**
```csharp
private void CopyGlobalConfigsToLocalFolder(
    DataModel.TestTemplate currentTest,
    List<IDASCommunication> dasList)
```

**Behavior:** Copies DAS and module configuration XML files from the current directory's `Constants.DAS_CONFIGS` subfolder to the test directory. Creates the destination directory if it does not exist. Catches and logs exceptions without re-throwing.

## 3. Invariants

- **Thread Safety:** All configuration operations within `SetConfig` are protected by a lock on `DASHardware.GetArmStatusLock`.
- **Voltage Threshold Ordering:** The code does not explicitly validate that minimum thresholds are less than maximum thresholds.
- **Configuration File Naming:** DAS config files are named `{OwningDAS}.xml`; module config files are named `{SerialNumber}.xml`.
- **Callback Completion:** Both `ResetHardwareLines` and `SetConfiguration` operations block
