Your computer system configuration at startup can affect the amount

of RAM available for use by the Offline Programming Software.

DOS offers a number of options that can help increase the amount of

RAM available to programs.

With DOS versions 5.0 or earlier you can maximize available RAM

by editing your CONFIG.SYS file. Your CONFIG.SYS should

contain text lines similar the following:

DOS=HIGH, UMB

DEVICE=C:\DOS\HIMEM.SYS

BUFFERS=10

FILES=10

STACKS=9,128

In the example above, the BUFFERS, FILES, and STACKS values

are set to low values to conserve RAM for program operation.

Important: The line DOS=HIGH,UMB should be used only with

DOS versions 5.0 or higher.

DOS version 6.0 introduced the MEMMAKER command, which

automates memory management and can often free large amounts of

RAM. DOS 6.0 and higher versions also allow you to create multiple

configuration files from which to choose at startup. This feature can

prove useful on PCs used for programming the DL40 as well as other

activities.

Refer to your DOS user manuals for information on creating and

editing CONFIG.SYS files, techniques for optimizing memory, and

using multiple configuration files on a single PC.

The Offline Programming Software can be installed and run in any

of three distinct environments:

• without PassThrough file transfers

• with PassThrough file transfers over a DH+ link

• with PassThrough file transfers over an Ethernet link

Installation of the basic Offline Programming Software is the same

for all three environments. You will have to perform additional steps

to install PassThrough capability on either a DH+ or Ethernet link.
