Description and Specifications
WiPort™ Integration Guide
14
Ethernet communication lines connect to external magnetics and an external RJ-45
jack. They are used for the creation of an Ethernet interface (instead of using the
wireless interface). Either Ethernet or WLAN is selectable for communication (not
both).
Ethernet Link LED 1 can be used to drive an external LED. The LED is on when a
link exists.
Ethernet Activity LED 2 is also used to drive an external LED. The LED blinks when
activity is present.
