FIGURE 30 - ET HERNET SCHEMATIC

A 10/100 Ethernet PHY interface is supported when the Ethernet device type is selected in firmware. This interface is a 10/100Mbps interface that supports auto negotiation and cross-over cabling. The interface also supports both half and full duplex for 10Mbps and 100Mbps.

The interface uses a Broadcom BCM5241A Ethernet PHY, please refer to the manufacturers datasheet for interface details and appropriate design guidelines for both capacitive coupling and magnetic interface.

The direct connection is available through CN3 (5.6) and requires J8 (5.21) to be configured correctly. If CN3 is used the most common connection method is capacitive coupling directly to a second PHY.

The WLN_CFG LED ON indicates the Airborne Device Server module has installed a valid IP address and is available for network communication.

It may take several seconds for the WLN_CFG LED to turn ON after the RF_LINK LED is ON, this delay is due to the DHCP lease process.

If static IP addressing is being used the WLN_CFG LED will turn ON after network services are available on the module. This will be a few seconds after POST has turned ON.
