Delivery
Release assets and typical scenarios
Preparation
Connect UCAN-Mini to the host over USB and confirm that the device enumerates normally.
Debug Flow
Open both CAN channels in the host tool and configure CAN / CAN-FD parameters.
Troubleshooting
Short press toggles 120R termination for both channels.
Typical Scenarios
Dual-Channel Bring-up
Open two CAN channels at once to validate controllers, nodes, or gateways.
Automated Testing
Combine host software, scripts, and driver support for R&D bring-up, production test, and data capture.
Upgrade and Maintenance
Use the USB channel for OTA upgrades during production maintenance and field updates.

Check these points before setup and integration.
Why does the host not find the device after switching modes?
After a protocol mode switch, the device restarts and re-enumerates. The host needs to detect it again and reconnect.
Can I quickly judge channel status in the field?
Yes. The system LED and each channel's TX / RX LEDs indicate startup state, current mode, transmit/receive activity, and bus error states.
