The Diagnostics menu provides tools for verifying a connected display, inspecting live data, and replaying logs. These pages act on the live device or on log files — they are not part of the saved configuration.
Trigger camera and installation test actions on a connected display.
Real-time channel plotting while connected to a display.
Enable or disable display backend modules at runtime.
Upload, select, and replay log files through Display Studio.
Diagnostics → Test Functions
Test Functions send one-shot commands to a connected display so you can verify installation without building a temporary screen layout.
| Action | What it does |
|---|---|
| Show Camera Full Screen | Shows the camera overlay full screen on the display |
| Hide Full Screen Camera | Hides the full-screen camera overlay |
| Select Camera Input 1–4 | Switches the active camera input |
Use these after wiring cameras to confirm the correct input and that full-screen preview works on the device.
Audio test actions appear in the list for future installation checks. Some may be disabled until the audio feature is available on your firmware.
Diagnostics → Live Plots
Live Plots shows real-time traces of selected channels while the display is connected. Use it to verify sensors, maths outputs, and timing channels without leaving Studio.
For longer capture and offline review, configure Logging and download logs from Home, or use Log Replay for files already on the PC or device.
Diagnostics → Module Control
Module Control lists backend modules running on the connected display. You can enable or disable non-critical modules at runtime to isolate problems or free resources while testing.
Some modules are marked Always on. They cannot be disabled at runtime because the display needs them for basic operation.
Diagnostics → Log Replay
Log Replay plays back recorded channel data so you can review a run without the vehicle running. Use it with logs downloaded from the display or files you upload from the PC.
| Action | Description |
|---|---|
| Refresh | Reload the list of available logs |
| Upload… | Add a log file from the PC (e.g. .elo / product log types supported by the dialog) |
| Delete | Remove an Uploaded log from the local list (device logs are not deleted from the display here) |
Select a log in the list to load it for replay.
After a log is selected, pick which channels to include in the replay stream. Use the search field to find channels by name.
Use the replay controls (play / pause / seek as provided on the page) to move through the recording. Live data and gauges that listen to the same channel stream will follow the replayed values while playback is active.
