DRIVE-CLiQ topology
NX components can be connected to the NCU via DRIVE-CLiQ. The following rules apply for
the wiring:
● Only one star topology is permitted between the NX and the NCU. In this way, only one NX
● DRIVE-CLiQ ports not assigned to NX can be wired to other DRIVE-CLiQ components.
● Once an NX has been connected and configured, you cannot simply insert it into a different
