Some older devices which are not adjustable by the Configuration Tool AS (only by DIP-
Switch or Hex-Switch, e.g. Standard 22, Distribution Unit) can only be set to one
combined “address” with a fixed CAN-Group. This means, that the configuration has effect
to the Unit ID and the CAN-Number (Unit ID = CAN-Number). In this case devices of the
compass system have a fixed CAN-Group of “2”.
Each Unit ID and each combination of CAN-Group and CAN-Number
must only be assigned once in the CAN-Bus System.
Explanations:
•
a CAN-Group identifies a product group respectively a sub-system
(e.g. compass = 2, NautoSteer = 6 - 9)
•
a CAN-Number is a unique ID within a CAN-Group
•
a Unit ID is a unique ID within a complete CAN-Structure
