Ethernet is a high-speed LAN widely used in commercial buildings. The main Ethernet network interface is
located on the motherboard of the product directly next to the serial RS-232 ports. A second Ethernet
connection, located next to the audio ports, is not active for use at this time.
The on-board Ethernet network interface supports 10Base-T (10Mbps), 100Base-T (100Mbps) and
1000Base-T(gigabit) Ethernet connections. The product will automatically switch to 100Base-T operations
if other devices and cabling connected to the same subnetwork support this.
