The DM5806 dataModule® general purpose digital I/O board turns your IBM PC-compatible cpuModule™ or

other PC/104 computer into a high-performance control system. Ultra-compact for embedded and portable applica-

tions, the DM5806 board features:

• 24 TTL/CMOS 8255-based programmable digital I/O lines,

• Direct connection to opto-22 I/O system modules,

• Buffered outputs for high driving capability,

• Optional pull-up/pull-down resistors,

• Simple I/O or strobed I/O operation,

• Three 16-bit, 8 MHz timer/counters,

• Software enabled interrupts (IRQ2-IRQ7),

• Requires +5 volts only for operation,

• BASIC, Turbo Pascal, and Turbo C source code; diagnostics program.

The following paragraphs briefly describe the major function of the board. A more detailed discussion of board

functions is included in Chapter 3, Hardware Operation, and Chapter 4, Board Operation and Programming. The

board setup is described in Chapter 1, Board Settings.

Digital I/O

The DM5806 has 24 TTL/CMOS-compatible digital I/O lines which can be directly interfaced with external

devices or signals to sense switch closures, trigger digital events, or activate solid-state relays. These lines are

provided by the on-board 8255 programmable peripheral interface chip. The 8255 can be operated in one of two

modes: Mode 0 or Mode 1. To ensure high driving capacity, CMOS buffers are installed. TTL buffers are available

on request.

Pads for installing and activating pull-up or pull-down resistors are included on the board. Installation proce-

dures are given at the end of Chapter 1, Board Settings.

8254 Timer/Counter

An 8254 programmable interval timer contains three 16-bit, 8 MHz timer/counters to support a wide range of

timing and counting functions. The clock, gate, and output pins for each of the timer/counters are available at P6, a

20-pin right angle connector.
