The RS-422 serial cables for downstream connections connect to the Node Controller using
either a 9-pin male ‘D’ connector on the end that plugs into the Node Controller LITE at any
of the even numbered RS-422 ports or a 4-pin female M8 connector on the end that plugs into
the NC-12 Node Controller at any RS-422 ports. The RS-422 serial cables connect to the
MagneMover LITE motor using a 4-pin female M8 connector on the end that plugs into the
last motor in the chain at the downstream communication port.
NOTE:
MagneMotion recommends that the upstream connection to the NC LITE Node
Controller always be made to an odd numbered (male DE-9) RS-422 port and the
downstream connection always be made to an even numbered (female DE-9)
RS-422 port. However, a custom crossover gender changer may be used to connect
an RS-422 DE-9 connector to the NC LITE Node Controller.
