Function
The CAN repeater automatically separates from a segment if the segment shows a
permanent disturbance level of +1 V ... +5 V between CAN-HI and CAN-LO. The
corresponding red LED is on. The other segment goes on working.
If the permanent disturbance level has disappeared, the segment is connected to the
system again through the CAN repeater.
