ECAN - U01S has 1 PWR indicator, 1 Work indicator, 1 CAN1 indicator, and 1 CAN2 indicator to indicate the
running state of the device.
The specific indication functions of these 4 indicator lights and the status of the CAN bus when these 4 indicator

error
After the ECAN-U01S is powered on, the four indicators light up at the same time, and then the PWR and Work
lights are always on , but the CAN1 and CAN2 lights are off, indicating that the device has been powered and the system
has completed initialization; otherwise, it indicates that there is a system power failure or other failures.
After the USB interface is connected normally, when the PC software calls the USBCAN device, the USB signal
indicator Work will flash. At this time, when CAN1 or CAN2 has data to send and receive, the corresponding CAN1 and
CAN2 indicator lights will flash. If Work is flashing but the CAN1 or CAN2 indicator is off, it means that there is no
data in the CAN channel, please check whether the wiring, communication baud rate, matching resistance, etc. are
correct.
