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. The following table describes the pinout/signal information.
