Introduction

The ACL-7122 - 144 Bit Digital I/O board is a high density
parallel Digital I/O board for ISA bus-compatible computer in
industrial applications. It is fully hardware and software
compatible with Advantech's PCL-722.

This board provides 6 sets to emulate industry standard 8255
Programmable Peripheral Interface (PPI) chips, each offers 3
por

ts: PA, PB, and PC. PC is

 subdivided into 2 nibble-wide (4-bit)

ports. Each channel has an individual connector with OPTO-22
pin assignment. It is very essential to use isolated input to
prevent the ground loop problems.

The ACL-7122 is programmed using simple 8-bit I/O port
commands. Users can use high level language, such as BASIC,
C, or PASCAL, or low level language, such as Assembly to
program the board. It is not any special software driver
supported.
