PWR
The Power LED is constantly on when the device is in normal operation. Exceptions to this are:
When a custom configuration file is rejected (the LED toggles each 500 ms a total of 10 times, then stays on).
When the firmware is being updated (for more information go to the Firmware update section).
CH1
The Channel 1 LED indicates CAN-bus activity.
Note
CAN-bus activity is indicated by turning the CH1 LED on for 25 ms. The LED will be constantly on if the time between CAN-bus messages is less than 25 ms.
Note
Activity on the USB virtual CAN bus does not trigger the LED.
MEM
The Memory LED indicates memory activity (eg. configuration parsing and USB memory access).
