SocketModem Configuration

Serial Configuration

The SocketEthernet IP uses a 23-pin interface to provide an on-board Ethernet media access controller, an Ethernet

physical layer (without the RJ-45 jack), an LED driver for Ethernet monitoring, and a serial interface.

Note: The shaded, bolded pins are SocketEthernet IP active pins.
