The MVME760 provides both AUI and 10BaseT interface via the
front panel of the MVME760 transition module. The AUI interface
and the 10BaseT interface are provided through a standard 2-row
DB15 connector and an RJ45 connector respectively.
Each pin connection, signal mnemonic, and signal description for
the AUI connector is listed in Table 3-2. The AUI connector shield is
tied to chassis ground.
