Display Software
Proper display functionality can be achieved only if the MW810 Display Control package is
installed. This package is a part of the MW810 CPU software image. When you use the
device with a laptop as the secondary display option, do not forget to install the display
software (refer to the Display Upgrade chapter in this document).
The MW810 Display Control package consists of:
• MWDisplayService - service application to access the display hardware.
• MWDll - provides API for third party or internal applications to
control and manage the display. It serves as an
interface engine between the MWDisplayService and
3’rd party or internal applications.
• MWAgent - provides notifications to the operating system about
specific display events.
• MWManager - simple application for troubleshooting.
• Extrakey - software utility that can assign specific function of the
operating system to a Function key that can be
activated by pressing this key.
