The DIO-144 Provides 144 TTL digital I/O lines. The DIO-144 emulates 8255 mode 0 and has an increased output current of 15 mA (source) and 64 mA (sink). This allows it to control LED, relay, etc. The DIO-144 consists of eighteen 8 bit, bi-directional ports and 2 input lines for interrupt enable and interrupt. The 8 bit ports are named port A(PA), port B(PB), and port C(PC). Port C can be split into two four bits. All ports are configured as inputs upon power-up or reset. The DIO-144 uses four I/O addresses. The base address is selectable from 200 to 3FF hex. The interrupt signal can be connected to any of the interrupt levels 2 through 7.
