LAN Interface

The LAN interface uses an Ethernet port that conforms to the IEEE 802.3 and 802.3u protocols and supports 10 or 100 Mbps half or full-duplex data rates on category 3 (10 Mbps) or category 5 (10/100 Mbps) twisted-pair wire at a distance of up to 100 meters. The Ethernet connector is an RJ-45. Table A-1 shows the connector pinouts.
