About Memory Managers

A memory manager is a software program that manages the use of memory in your

computer. If your computer has any expanded memory (EMS) or extended memory

(XMS) installed, you may be using some sort of memory manager.

In certain configurations, some memory managers may conflict with the following DH-

485 and DH+ network interface cards.

Allen-Bradley 1784-KT

Allen-Bradley 1784-KTX

Allen-Bradley 1784-KL

Allen-Bradley 1784-KT2

This section describes how to avoid these conflicts.

386MAX.SYS

386MAX.SYS is a memory manager produced by Qualitas, Inc.

There is an easy method to avoiding 386MAX conflicts with the interface cards.

386MAX is shipped with a program called MAXIMIZE.EXE. This program examines

your computer and makes certain that it won’t create memory conflicts with your

existing hardware. If you use MAXIMIZE.EXE to configure 386MAX, you should

have no conflicts with your interface. See the

386MAX User’s Guide

for more details.
