This document outlines the process to retrofit the facepanel keyboard to the newer version which uses
Cherry MX switches. There has been some minor variance in the USB cables used internally, and the
upgrade kit includes new compatible cables where applicable. These parts are backwards compatible with
all versions of Eos Ti and Gio consoles.

Note: This keyboard can only be used with Eos Family software version 3.1.4 or higher.


If you are replacing a keypanel with a white circuit board, the new keypanel will not exactly match the old keys on the rest of the console.  They will sit 1/16" deeper in the chassis, the text is not as white, and the clear, crescent keys are a bit clearer than the old ones.  These are subtle differences that aren't a big deal to most, but if it is a concern to you, you may want to consider purchasing the other facepanel button retrofit kits for Gio (see the article linked here to find the kits you want/need or call technical services for assistance).

Replacement older-style keyboards are no longer available for Eos Ti.


  1. Power down the console.
  2. Unplug the console from mains power.
  3. Remove the back panel cover over the motherboard underneath the display panel.
  4. Lower the display panel completely.
  5. Open the face panel by turning the 2 locks on the bottom of the chassis using a flat head
    screwdriver or coin.
  6. Carefully disconnect the current facepanel keyboard from all its connections. Take note of
    where items are connected as they will be connected similarly on the new keyboard. Taking
    a photo is recommended.
  7. To remove the facepanel keyboard, remove the indicated screws, do not remove any black
    screws labeled “DO NOT REMOVE”. BE SURE TO SAVE YOUR HARDWARE (namely screws).
    You will need the existing hardware to reinstall your new facepanel keyboard.Screws.JPG
  8. Install the new facepanel keyboard using the same hardware from the original keyboard you
    removed along with the included, foam light blocker as shown below.

    Note: Make sure the foam light blocker and keys are aligned appropriately to ease with installing the
    new facepanel Keyboard.

  9. If replacing a white keyboard, it will require the USB cable be replaced due to connector changes. If so, carefully
    trace the USB connection cable back to the motherboard of the console. Using cutters
    carefully free the cable from the cable ties. Take note of the cable path as the new USB cable should
    be routed in a similar fashion.
  10. If the motherboard's USB connector is a 5pin header, make sure the red wire is on pin1 or
    towards the front of the console. Otherwise it will be a normal USB A connector common
    to all PCs, and it should connect as usual. When in doubt, check fitment prior to removal and
    connect exactly as the old one was.
  11. Route the new USB cable to the facepanel Keyboard using the provided cable ties to rebundle.
  12. Lower the console face panel, locking it closed.
  13. Re-Install the back panel cover.
    Note: You may wish to test the keyboard functionality before re-installing all the screws.
  14. Plug in mains power and turn the console on.
  15. Navigate to ECU->Settings->Maintenance and launch the Face Panel Test application to
    verify functionality.
  16. Press each button, rotate the level wheel and test each encoder to make sure connections are
    as expected. If all looks as expected your new facepanel keyboard is correctly installed.
