Each pin connection, signal mnemonic, and signal description for
the 10BaseT connector is listed in the following table. The 10BaseT
connector shield is tied to chassis ground.
IEEE P1284 Parallel I/O Connector
The parallel I/O connector is a standard IEEE P1284-C, 36-pin
receptacle on the MVME760 front panel. The functionality of each
signal depends on the mode of operation of this bi-directional
Parallel Peripheral Interface. Refer to the IEEE P1284 D2.00
Standard for a complete description of each signal function.
The pin assignments for this connector are shown in the following
table. The parallel port connector shield is tied to chassis ground.
