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.
Relay Port: Connections and Wiring
You can connect up to 8 independent external relay devices on both the NI-4000 and NI-3000 units (4 on
the NI-2000) to the Relay connectors on the Integrated Controller.
Connectors labeled A are for common; B are for output.
Each relay is isolated and normally open.
A metal commoning strip is supplied with each Integrated Controller to connect multiple
relays.
Relay Connections
Use A for common and B for output (FIG. 6). Each relay is isolated and normally open. A metal
connector strip is also provided to common multiple relays.

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.
