 ### DUT Module (dut_module)
 The DUT module configures the individual DUT interfaces.
 Where each interface can be set to one operating mode.
-The possible modes are 'aida', 'aidatrig' and 'eudet'.
+The possible modes are 'aida', 'aidatrig', 'eudet' and 'eudet_with_busy'.
 With 'aidatrig' the AIDA mode with additional trigger number.
 And 'aida' or 'eudet' the AIDA or EUDET operating modes.
 It is important to note that only working DUT devices should be enabled.

 | Configuration | Description | Type | Default Value |

 | `internal_trigger_rate` | (Optional) Generates internal triggers with a given frequency given in Hz. | Integer | 0 |
-| `dut_interfaces` | (Required) Specify the operation mode of the DUT interface (`aida`, `eudet`, `aidatrig`, `off`), given as list with a required length of 4. `aida` and `eudet` correspond to the classic AIDA and EUDET mode respectively and `aidatrig` to the AIDA-mode with handshake. Disable a DUT interface with `off`. | List | None |

 | `trigger_inputs_logic` | (Required) Trigger Logic configuration accepts a Python expression for the trigger inputs. The logic is set by using the variables for the input channels `CH1`, `CH2`, `CH3`, `CH4`, `CH5` and `CH6` and the Python logic operators `and`, `or`, `not` and so on.
