Portable Program Download Device 
(PPDD)
The Portable Program Download Device enables the user 
to easily upload and download VersaMax Micro 23/28 con figuration and logic from/to a USB Memory Stick. Portable 
Program Download Device (PPDD) will support commercial 
memory stick devices using USB connection. The purpose of 
the PPDD is to allow users to store and download their logic 
applications and configuration to GE VersaMax Micro 23/28 
PLCs without the need of a PC. The PPDD plugs into the 15 
pin RS-485 port on the VersaMax Micro 23/28 CPU base 
power supply. The RS-485 port provides the power for the 
PPDD. VersaMax Micro 23/28 logic and configuration files 
can be zipped and easily emailed to remote locations for 
VersaMax Micro 23/28 downloads. 
There are many advantages of the PPDD such as:
•No PC required to backup applications or download applications
•No expensive travel to perform field upgrades, just email the file to the remote location
•Compatible with commercial off the shelf USB Memory Sticks
•The PPDD can be panel mounted, DIN rail mounted or hand held
•Supports diagnostics to ensure that the CPU is compatible with the application
•OEM Password Protection supported
•Simple to operate, LEDs to show activity, error and status. Push button to start download and selector switch for

Remote location takes the binary 
file that is in the email and stores 
it on a USB memory stick. 
Email binary file
Step 4.
Place the USB memory stick in the PPDD, slide selector toward 
controller. Press PPDD download button. The PPDD will stop 
the CPU and download/verify file. The CPU can be placed in 
the Run mode via the key switch or cycling power.
