RJ-45 connector - pin configurations

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.

ICSHub OUT Pinouts and Signals

Pin	Signal	Color
1	RX +	orange-white
2	RX -	orange
3	------	------
4	------	------
5	------	------
6	------	------
7	TX +	brown-white
8	TX -	brown

Relay Port: Connections and Wiring

You can connect up to 8 independent external relay devices on both the NI-4100 and NI-3100 units (4 on the NI-2100) 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. 17). Each relay is isolated and normally open. A metal connector strip is also provided to common multiple relays.
