INTRODUCTION
OVERVIEW
The G4LC32ISA-LT processor is a low-cost, general purpose, industrial microcomputer that’s mounted
on a standard IBM PC ISA bus card. Its low cost, size, and flexibility make it ideal for original
equipment manufacturers, machine control, test stations, laboratory automation, and various data
concentrator and collector applications. The result is an innovative hardware/software solution that
includes intelligent I/O and OptoControl — an advanced software control language. This tightly-
integrated package allows you to quickly and easily implement your industrial control applications.

The G4LC32ISA-LT shrinks the “Two Box” Computer Integrated Manufacturing (CIM) control
architecture into a “One Box” package. While still maintaining the performance of a two-tier
processor architecture, the industrial PC, in conjunction with the G4LC32ISA-LT, can operate a
complete system of highly intelligent I/O modules in real-time, while simultaneously providing CIM
functions such as operator interfacing, maintenance diagnostics, SPC, SQC, CFM, logistical tracking,
data entry, historical logging, trending, and host interfacing. Compatible with Opto 22’s real-time
control languages (OptoControl and Cyrano), and man-machine interfaces (OptoDisplay and Mistic
MMI), the G4LC32ISA-LT can be programmed to suit many types of industrial control applications.
The G4LC32ISA-LT is operated as a slave co-processor and may be mounted in either an active or
passive ISA backplane. Multiple slave-configured G4LC32ISA-LT processors, each with their own I/O,
may be installed in a single PC. As a slave, the only resource the G4LC32ISA-LT needs from the ISA
bus to run is power. Thus, you may reset the PC, and the G4LC32ISA-LT will continue to operate.
