   *   `DEPTH`: Align color to depth.
   *   This parameter is case-insensitive. Hardware D2C only supports `COLOR` as the target stream; use `align_mode:=SW` if you need to align to `DEPTH`. See [Aligning Depth to Color](../5_advanced_guide/configuration/align_depth_color.md) for startup and viewing examples.
 - **`intra_camera_sync_reference`**
-  - Sets the reference point for intra-camera synchronization. Applicable for Gemini 330 series devices when `sync_mode` is set to **software** or **hardware trigger** mode. **Options:** `Start`, `Middle`, `End`. When empty, the node leaves the device's current setting unchanged.

   *   `DEPTH`：将彩色对齐到深度。
   *   该参数大小写不敏感。硬件 D2C 仅支持 `COLOR` 作为对齐目标；如需对齐到 `DEPTH`，请使用 `align_mode:=SW`。启动和查看方法参考 [对齐深度到彩色](../5_advanced_guide/configuration/align_depth_color.md)。
 - **`intra_camera_sync_reference`**
-  - 设置相机内同步的参考点。适用于Gemini 330系列设备，当 `sync_mode` 设置为**软件**或**硬件触发**模式时。**选项：** `Start`、`Middle`、`End`。参数为空时，节点不修改设备当前设置。
