Pin out – I/O connectors

The CIO-DUAL-AC5 I/O uses two 50-pin header-type connectors. These connectors are board-mounted and

are not accessible on the rear of the PC expansion backplate. The signals available are direct connections to an

82C55 digital I/O integrated circuit.

Figure 2 shows the pin outs for the connectors. The pin assignments for each are identical for each group of 24

pins (three, eight-I/O ports).

 The front connector (P1) is for first Port A, first Port B, and first Port C I/O lines (at BASE + 0, 1, and 2).

 The rear connector (P2) is for second Port A, second Port B and second Port C (at BASE + 4, 5, and 6).
