channel. The LED(s) are lit
(light red) when the signal
is active (logical 1).

communication quality of
the CAN communication for
DCH software. The LED is
lit (light green as the
picture shows) during the
time the CAN
communication is enabled,

transmitted between both
channels and that data is
irrelevant to be displayed.
