Based on the cables connected and the position of the DIP switch, the CAN processor detects
which functions are to be controlled and at which location each assembly is.

Cable assignment at connector X1
The power connection has 2 pins for selection of the suitable CAN ID. This depends on the
position (location) of the CAN node module in the machine.
NOTE: The old nozzle changer of the C&P20 head can not be used together with the CAN node
NC tape cutter module.
The nozzle changer with new control board can also be used in machines without the CAN nodes.
