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.
