The CANTCU Configurator provides access to configuration, diagnostics and realtime data from the main interface.
The main interface consists of:
- CANTCU information and connection status
- Section navigation
- Main content area
- Device/CAN-bus indicators and graph/datalogging controls
- Realtime values
¶ Graph & Gauges
The Realtime section can display live values from CANTCU, the ECU and transmission as graphs and gauges.
- Click a realtime value to add it to the graph.
- Left-click adds the value on the main graph axis, right-click adds a secondary axis.
- Click a gauge to change the value/scaling and gauge type displayed by that gauge.
- Presets can be added/removed from the upper preset bar.
- Extra settings for graphs like saving an image or positioning the legend can be found by right-clicking the graph area.
Graphs and gauges can be displayed separately or together.
A slower refresh mode is also available for older or slower computers.
¶ Indicators
Device indicators show the communication status of connected devices.
- Green = connected
- Red = not connected
CAN-bus indicators appear when a physical communication problem is detected on the corresponding CAN bus. Typical causes include incorrect CAN speed or wiring problems.
CAN-bus indicators remain hidden when no problem is detected.
¶ Realtime Values
Realtime values can be viewed, graphed and logged through the CANTCU Configurator.
