ETHERNET (RJ-45) Port
The RJ-45 port provides 10/100 Mbps communication communicates with the NetLinx Master (via
ICSP protocol over Ethernet). The Ethernet port automatically negotiates the connection speed (10 Mbps
or 100 Mbps), and whether to use half duplex or full duplex mo de. This communication is reflected via
the front ICSP LED.
FIG. 16 describes the blink activity for the ETHERNET 10/100 Base-T RJ-45 connector and cable.
The following table lists the pinouts, signals, and pairing associated with the ETHERNET connector.
FIG. 17 diagrams the RJ-45 pinouts and signals for the ETHERNET RJ-45 connector and cable.
