Application and tool settings

Open Settings in the main window. The following sections apply to beta testers. Control names match the application interface.

Section	Purpose
Account	Sign-in, activation, license expiry and autonomous use
Application → Profile	Select a profile and module
Application → Startup	Automatic connection and active serial port scanning
Application → Personalization	Theme and accent color
Connections → Transport	Communication source and connection parameters
Connections → Driver Bridge	32-bit J2534 driver bridge, when the component is installed
Tracer	Import folder and quick-label shortcut
Monitor	Data change highlighting
Packages	Install, repair and update components
MCP Server	Agent permissions and McpBridge control
Logging	Technical log file and recent events

Without a valid license, some settings are hidden; account, appearance and logging remain available. A group containing only one page may display that page without an intermediate group node.

Startup

Automatic connection on start-up allows connecting at startup with saved parameters. Check the selected module, port and speed before enabling it.

Active adapter detection

Active serial port scanning in Settings → Application → Startup enables automatic identification of CANable, WeAct and UCCB adapters through serial ports. It makes available adapters easier to find at startup and when you click Rescan in transport settings.

Possible unwanted traffic

Active detection opens ports and sends data to connected devices. Depending on the device, this data may reach the bus and generate unwanted traffic. This can happen as soon as the application starts, before you connect to the line in the application, and when you click Rescan.

If additional traffic is unacceptable, disable Active serial port scanning before starting the application with an adapter attached to the working bus. If necessary, disconnect the adapter from the bus first, start the application, and change the setting. Disabling it stops automatic identification of CANable, WeAct and UCCB adapters. The setting applies to the next scan; disabling it does not turn off automatic connection or other operations that send data.

Appearance

Theme selects Auto, Dark or Light. Auto follows the Windows theme. Use system accent color follows the system accent; disable it to select a custom color.

Tracer

• Remember last import folder remembers the folder used for loading traces.
• Capture → Quick label shortcut selects a quick-label key with the required Ctrl modifier. The default is Ctrl+L.

The details panel position, size and pin state, CAN column widths and filter expressions are saved while using Tracer. These are display preferences, not adapter settings.

Monitor

Dynamic highlight controls how data changes are displayed:

Setting	Effect
Enabled	Enables dynamic highlighting
Stale after, s	Time since the last value change until its highlight fully fades, from 5 to 60 seconds
Stale data opacity	Opacity of an unchanged value, from 0 to 1
Outdated after, s	Time since the last data observation until the row fully fades, from 5 to 60 seconds
Outdated data opacity	Opacity of an outdated row, from 0 to 1

Stale means a value has not changed recently: repeated identical data remains current. Outdated means no new data has been observed within the selected interval. It indicates age, not a data error. Observing data again restores the row's opacity, but an identical value does not restart the change highlight.

Highlighting is enabled by default, with both intervals set to 5 seconds. The intervals are independent and fading is gradual. Settings apply immediately to CAN and Modbus, are saved, and do not change the communication rate or device polling period. When loading older settings, the previous shared interval is used for both effects with a minimum of 5 seconds; a previous zero value keeps highlighting disabled.
