DIL/NetPC DNP/2486: 64-pin DIL Connector Pinout

The mechanical interface between the DIL/NetPC DNP/2486 and existing devices and equipment is a JEDEC 64-pin DIL connector with 2.54mm centers. This allows the direct integration to a standard 64-pin DIL socket. The 64 pins in total are used for 3.3 volt power supply (2 pins), Reset in and out (2 pins), two serial interfaces (10 pins), 10BASE-T and 100-BASE-TX Ethernet interface (4 pins), general purpose parallel I/O (20 pins), I/O extension bus (24 pins) and USB host port (2 pins).
