INSTRUCTIONS, G4 USB EASY PROGRAMMING
There are two methods that can be used to change the default settings on G4 brewers. They can be programmed at the brewer by the touch screen universal control module (UCM) or the settings can be changed 
using the USB (Universal Serial Bus) data port on the side of the brewer. Using the USB connection and a 
ash memory data storage device will easily reprogram the settings simply by copying data. 
The ash drive can upload or download the entire setting from one G4 brewer, into another G4 brewer. This 
eliminates the need to walk through the usual steps in reprogramming that would be required when you use 
the touch screen to make a change. This is an advantage for a service technician when standardizing the program settings on multiple G4 brewers.
Use a USB drive with USB 2.0 support and a type-A USB connection. Storage capacity should be 2 GB minimum (reference the illustration on page 2).
UPLOAD
1.  Make sure the brewer is on. Determine that the G4 brewer you wish to copy is properly programmed for 
your desired settings. 
2.  Connect an empty ash drive into the USB port on the 
brewer. The UCM on the brewer will upload all of the 
particular setup data onto the ash drive. The yellow LED 
on top of the touch screen will light indicating that data is 
transferring. This will only take a second to complete.
DOWNLOAD
1.  Select the brewer you wish to make the program changes 
on. The brewer should be on. 
2.  Plug the loaded ash drive into the USB port on the brew-
er. The data copied from the rst G4 brewer will automatically download, overwriting all the settings that were on 
the second brewer. 
3. The red LED on the UCM will indicate that the download is in process. This will only take a second.
4. Once the download is complete, the UCM will reboot in order for the changes to take effect. As long as the 
ash drive is left in the USB port, the controller will continually download and reboot. 
5. Remove the ash drive. The download is complete. The data on the ash drive can be downloaded into as 
many G4 brewers as needed.
