The DIO-48 provides 48 TTL digital I/O lines, and one 16- bit counter . The DIO-48 emulates 8255 mode 0 and has an increased output current of 15 mA (source) and 64 mA (sink) , allowing it to control LED, relay, etc. The DIO-48 consists of six 8-bit bi-directional ports and 3 input lines for interrupt enable and counter. The 8-bit ports are named port A(PA),port B(PB) and port C(PC). The port C can be split into two four bit. All ports are configured as inputs as inputs upon power-up or reset. 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.
