Installation and Wiring
11 NXC-ME260 NetLinx Master-Ethernet Card/Module
ICSHub RJ-45 Connections/Wiring
The two ICSHub RJ-45 connectors on the rear of the Master card provide data to other Hubs
connected to a downstream system. Hubs allow you to connect multiple NetLinx Hubs together in a
daisy-chain configuration. Connect the OUT port to the IN port on the second or downstream
NetLinx Hub.
Use CAT5 cables for all ICSHub connections.
Do not connect the last hub in a daisy-chain configuration into the first Hub.
ICSHub IN port
The following table describes the pinout and signal information for the ICSHub IN port.

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.
