•
A 10/100BaseT Ethernet Interface (LAN interface) with Auto-negotiation
supporting Ethernet and IEEE 802.3, 1998 access protocols. Auto-negotiation of the
data rate (10 Mbit/s or 100 Mbit/s) and of the mode (full duplex). The
10/100BaseT Ethernet Interface access is via a RJ45 connector.
•
A 1000BaseT Ethernet Interface (LAN interface) with Auto-negotiation supporting
Ethernet and IEEE 802.3, 1998 access protocols. Auto-negotiation of the mode (full
duplex). The 1000BaseT Ethernet Interface access is via a RJ45 connector.
•
A 1000BaseX Ethernet Interface (LAN interface) with Auto-negotiation supporting
Ethernet and IEEE 802.3, 2002 access protocols. Auto-negotiation of the mode (full
duplex). The 1000BaseX Ethernet Interface access is via LC connector.
