Common questions

The software cannot find my device. Check the USB connection and click Refresh on the Home tab. Device names in the list are display names, not fixed COM ports.

CAN send fails and Trace shows an ACK error. No node acknowledged the frame. Check that the device under test is powered, CAN_H and CAN_L are correct, the bitrates match and the bus is terminated.

Why did transmission pause? After a TX timeout or Bus-off, the application pauses CAN transmission and the status bar shows TX paused. Fix the cause, then stop and restart measurement to resume.

The device under test sends nothing. Some ECUs stay silent after power-up until they receive specific periodic frames. Check its wake-up conditions.

Two LIN nodes are sending headers. A network can have only one master. If one already exists, set BeiniLink to slave.
