ICSNet Port: Connections and Wiring
The NI Controller must be equipped with the available ICSNet connectors for this functionality to be active. The following tables
show the signal and pinouts/pairing information:
NOTE:
Unlike the ICSNet ports, the ICSHub connections require a specific polarity. The IN/OUT configuration on the hub ports was
implemented to use the same cables as ICSNet, but these ports need TX and RX crossed. You must connect an OUT to an IN, or an IN
to an OUT port. This is done simply to keep the polarity straight. The Hub bus is still a bus. All Hub connections are bi-directional.
ICSHub OUT Port: Connections and Wiring
The NI Controller must be equipped with the available ICSNet connectors for this functionality to be active. The following table
describes the pinout/signal information for the ICSHub OUT port located on the rear panel of the Integrated Controller.
