: Due to the large file size, it is recommended that the [Open] button 

not be used because this would try to run the self-extracting executable from 
the web site. 

Installing Universal PST 

 
After downloading the software file from the Woodward web site, run it and 
follow the installer instructions. 
 
IMPORTANT:  
The installation program will detect operating system components older than 
those required by the "Universal PST" application. In this case the installation 
program will ask if you want to update Windows. If you do not want "setup" to 
update your system then you cannot use the "Universal PST" application on 
this computer.  
 
Read the setup program's instructions carefully as they appear and respond 
as needed. The installation may take as long as 7 minutes depending on 
your computer's power and operating system. Do not interrupt the installation 
program even though it may appear as  
though it is not running.  
 
NOTE: Administrator rights may be needed to install on some Microsoft 
Windows operating systems (such as Windows XP Professional) for the 
setup program to properly register application resources. 
 

Wiring the COMM Port to a PC 

 
To construct a communications cable to use between the DPG’s COMM port 
and your PC’s RS-232 serial port refer to the table and wiring diagram below.
