Description
The power indicator is always on after power on
System running indicator. When the device is not ready
to start or fails, the red indicator is steady on; when it is
running properly, the green indicator flashes
LAN working indicator flashes when data is sent and
received
The LAN working indicator is steady on when Ethernet
is physically connected
Green indicator on or flashing: Data is sent or received
on the CAN port
Green indicator off: No data is sent or received on the
CAN port
Red indicator on: An error occurred on the CAN port
