Interface Description
10/100 Ethernet with full- and half-
duplexing
This interface consists of an RJ45 connector and transformer
connected to the EPXA1 using an external MAC/PHY device connected
to the EBI
Expansion headers These headers are used to connect Altera daughter cards or customer-
designed daughter cards to develop and test custom circuitry
IEEE Std. 488 RS-232 serial interfaces This is a 250-kbps true RS-232 data terminal equipment (DTE) interface
Debugging/programming ports The board supports in-circuit debugging by means of the MasterBlaster,
ByteBlasterMV, or Multi-ICE cables
