Ethernet Operation
The Ethernet interface supports 100Mbit/s full duplex operation only. Data is transmitted from one port
the other port with minimum delay or buffering.
The port implements "Auto MDI/MDIX" i.e. it may be connected with either a straight-though or cross-
over cable to an appropriate device such as external switch, PC or other DCE/DTE.
Two LED indicators are provided adjacent to the RJ-45 port: Green indicates Link / Data transfer and
Yellow indicates no Ethernet connection.
