XO FLOW SOFTWARE VERSIONS
Version 1.9 (Released 2023-07-10)
Remote desktop
- It is now possible to have different remote desktop apps connect to different remote computers.
- Fixed a bug that caused the unit to briefly freeze when a remote connection failed to be established.
Virtual keyboard
- Symbols on the touch screen keyboards updated. This should fix the issue of some symbols and characters not being accessible (‘?’ and capital ‘L’).
- During startup the software will check if the Windows touch keyboard is enabled and, if so, disable it automatically. Now at most one keyboard should be shown on the navigator.
- Fixed a bug causing the close buttons on the touch keyboard to not function properly.
- Fixed a bug that would sometimes cause textboxes to be hidden when the touch keyboard was shown.
Asepsis
- Fixed a bug causing water disinfection asepsis procedures to fail if an instrument was pulled forward after the procedure was started.
- Tweaked timing of some asepsis tasks to avoid timeout errors in situations where the water tank takes a long time to depressurize.
- Update message shown when a system asepsis procedure fails. The message now simply reads “Procedure failed” instead of showing an internal error code.
Intraoral camera
- Fixed a bug causing the framerate of the video feed from the intraoral camera to drop occasionally.
- Fixed a bug causing the video feed to stop showing when another instrument was pulled forward.
- Fixed a bug related to the framerate of recorded videos.
- Fixed a bug causing videos opened from the camera app to be opened as still images in the image app.
- Fixed a few minor user interface-related bugs.
- Improved the UI for configuring network locations.
Other
- Operating light will no longer switch on when entering the entry position (if the option to switch it on when reaching a working position is enabled). (known error in 1.6)
- Next preventive service date added to status app.
- It is no longer possible to bind the “side-menu only” XO Odontocure activation function to foot control inputs.
- Removed a test function for the XO Odontoscaler from the list of configurable functions. This function was intended for internal use only.
- Updated the default foot control configuration for intraoral cameras so that the X and O buttons have no function.
- Changed the default drive air amount for micromotors to 80 %.
- Color of warning icon shown in dashboard changed to orange.
- The “limit foot control pedal range” feature is enabled by default for new users.
- Support for bien air motor driver software v 2.03
- Error 511 “got keep alive but instrument not running” error message is no longer displayed in the instrument information window.
Software 1.7 and 1.8 (have not been released)
Version 1.6 (Released 2023-04-24)
Instrument support
- Added support for Bien-Air MCX micromotors
- Support for Dürr “VistaCam iX HD Smart” intraoral camera, including:
- New “camera app” for capturing video and still images using an attached intraoral camera
- New “images app” for displaying, sharing and managing videos and images stored on the unit
Presets and workflows
- Presets and instrument workflows are now hidden on the Dashboard by default when creating a new user. Users must enable presets and workflows (from the user settings app) to use them. Makes the user interface more simple and easier to understand for users that does not need the preset and workflow functionality.
- Activation of an instrument workflow no longer results in the first workflow step being automatically selected for the related instrument.
- Extended the selection of icons usable with workflow steps.
- It is now possible to select “no icon” for preset and workflows.
Accessibility
- A new “help app” for accessing the instructions for use and various videos for e.g. unit disinfection and replacement of unit consumables has been added. Note that an internet connection is required to use this app.
- Removed the option to create new users with “classic XO settings”.
- German, Danish and French translations improved.
Instrument control
- Added virtual indicator lights to the panels of the instrument control windows, indicating the current spray selection for the associated instrument. Making it easier for the user to see the actual spray setting.
- It is now possible to disable the open/close “curtain” function of the instrument control window panels and have the panels open and close instantaneously when an instrument is pulled forward. Some users have asked for this feature to save time.
- New three-state (spray -> air -> no spray) spray select functions added for the two Bien-Air micromotors.
- A new two-state (spray -> no spray) spray select function added for air instruments.
- Added a function for activating the polymerization light from the dashboard side menus.
- Updated the way speed levels are handled for micromotors are handled to better account for gearing.
- When the reciprocating endo feature is used the text “150° CCW/30° CW” is shown instead of “ACTIVATED” in the instrument data window.
- The dynamic range of the foot control pedal can now be limited so that the deadband at the end of the range is larger. Some end customers complain that the foot control slides on the floor. This new software feature will reduce this problem as the maximum speed is reached before the pedal reaches the physical end stop. Another very important action to be taken is degreasing the foot control “feet” with petroleum benzine – see section 11.2 in the new IFU.
- Cool air for micromotors is disabled when maximum speed is set below or at 2.000 RPM and spray air is disabled.
Foot control
- The default foot control configuration for new users has been updated so that the pedal down activation of the foot control is bound to the three-state spray select function for Micromotors, the two-state spray select function for air instruments and to the enable/disable irrigation for scalers. To resemble the function of classic XO units.
- Default foot control updated: The X and O buttons can now be used to select the next/previous preset or workflow step when an instrument is selected.
Messages
- The “hardware information” section of the status app has been renamed “system information” and now also includes a readout of the installed software version.
- System messages shown in the status app, are now shown in their expanded state. It is no longer necessary tap a message to show the detailed information.
- The option to have the operating light automatically enter “composite mode” when a polymerization light is pulled forward has been removed.
Asepsis
- Instrument light is now automatically switched off when an asepsis procedure is started.
- The verbosity of errors and user prompts in the asepsis mode has been increased.
Other
- A new app for integrating with Medit scanner software on a remote PC has been added.

INTRODUCTION
The XO FLOW dental unit is equipped with an instrument bridge [1] with an integrated touch screen (the Dashboard) for controlling and monitoring the unit and the instruments – and with a smart device user interface [2] in the form of the Navigator (touch screen on a long and flexible suspension arm).

The user interface is powered by an internal computer [3] running an embedded version of the Windows operating system.
The internal computer can be connected to a local area network (LAN) by means of an ethernet cable.
The Navigator user interface consists of a home screen and set of apps and is, functionally, like the user interface of any modern smart phone or handheld computer.

REMOTE DESKTOP APP
The remote desktop app makes it possible to use the Navigator for displaying and interacting with a remote Windows computer connected to the same network (but not necessarily in the same room) as the unit.
The figure below illustrates how the remote desktop app works:

The unit is via an ethernet cable connected to a remote computer. Whenever the remote desktop app of the unit is activated, the Navigator will show the same picture as is shown on the clinic computer. Using the touch surface of the Navigator the user can manipulate the remote computer.
When setup properly, all the software installed on the remote computer can be accessed from the Navigator (whenever the Remote desktop app is active). This includes, but is not limited to, PMS systems, imaging system and scanning software.
PREREQUISITES AND SETUP
To use the remote desktop solution, the following must be observed:
- The unit and the remote PC must be connected to the same local area network. The unit must be connected using a wired connection, but the PC can be connected wirelessly.
- The remote PC must run Microsoft Windows and be configured to allow remote assistance.
- A XO server program must run on the PC with administrative privileges. This program is used to establish the connection with the unit. The program is a “background program” and can be set to start automatically.
- The PC should, preferably, be assigned a static IP address on the local area network. This address is used by the unit to identify the PC on the network.
- The remote desktop is configured to access the computer by entering the IP address of the PC in the settings.
- To work properly, the PC should have one screen with a HD resolution (1920x1080px) and UI scaling should be disabled. If these recommendations are not fulfilled, the image on the Navigator will be distorted and/or the Touch inputs from the Navigator will not map properly to the PC screen.
OTHER CONSIDERATIONS AND LIMITATIONS
Please also observe the following:
- The solution requires remote access to the PC to be enabled. The security concerns associated with this should be considered before proceeding. As a minimum, provisions for disallowing access from the outside (“the internet”) should considered. Note that cyber security is the responsible of the clinic owner.
- When accessing a computer remotely, the quality-of-service will, in some scenarios, be inferior to using the computer directly. The image stream of the compute must be transmitted across the network and it will not be possible achieve the same frames-per-second (screen update frequency) as is possible on the computer itself.
- It is advantageous to configure the remote PC to be used for touch interaction. Windows can, for example, be configured to show a virtual keyboard whenever a textbox is focused. This will greatly enhance the user experience when using the Navigator.
- For the time being, it is only possible to connect to one remote PC.
- The computer inside the unit does not store or retain any information from the connected PC.
- Note that the user experience (when accessing e.g. films) on the Navigator may be impaired due to the need for updating the Navigator display across the network.
INTEGRATION WITH THIRD PARTY SCANNERS
One clever use of the remote desktop app is to access scanning software from the navigator, eliminating the need for a cart computer.
See illustration below.

Please note that the remote computer can physically be situated in another location as the units and the camera can be connected to the remote computer via a Wi-Fi connection.
