Abstract:
The files in this self-extracing ZIP file can be used to upgrade the firmware
on a DCX-AT200 motion controller. Download the file and run it under a DOS
prompt to extract the compressed files. If the DCX-AT200 already has firmware
revision 3.6a or later installed, the Flash Wizard can be used to upgrade the
firmware on the controller. The Flash Wizard is a program that can be run
under Windows 95, 98 or NT. You can download the Flash Wizard, form the
support area of Precision MicroControl's Web site at www.pmccorp.com.

To determine what revision of firmware is installed in a DCX_AT200, run the
WINCONTROL program under Windows, or the DCX2CTRL program under DOS, and type
VE<enter> at the prompt. The controller will display the currently installed
firmware revision number. If the existing firmware is older than 3.6a, or the
update process fails, the included text file FLASHAPP.TXT describes how to
perform a lower level update using FLASH.BAT.

The text file DCXAT200_PM1_xxx.TXT contains a complete revision history for all
firmware updates. If you have any difficulty using these files, please contact
