Displays
The USB-to-CAN interface has two 2-colored LEDs. One LED is allocated to the
USB bus, the other to the CAN bus.
If the USB LED is lit green, communication with the interface via the USB port is
possible. If communication is not possible, the USB LED is lit red.
The CAN LED flashes green with every message received or transmitted without
error. If the CAN controller is in “Error warning“ or “Error passive“ mode, the LED
flashes red with every message. If the CAN controller is in ”Bus off“ mode, the
LED is permanently lit red.
