The Ethernet port on the Smart Building Hub is an 8-pin RJ-45 jack. The maximum allowable cable length is 100 m (328 ft).
Note: If you use the Ethernet port to connect to the MS/TP bus, power must be supplied by an external supply that is not the USB connection or the FC bus connection. External power supply hardware varies by market. For information on the external power supply provided, see the LED Test Sequence at Startup section.
