The panel provides up to a maximum of 16 page configurations with 72 switches per page. Each page can be entirely unique or can share key assignments with other pages. For maximum versatility, each LCD switch can be assigned a source or a destination or a salvo or a level, as well as any available control function. A page may contain a mixture of any of the above key types and all labels on the LCD switches are dynamically updated as the system configuration is changed. Key switch background colors are assigned per a system wide default color scheme. Backlight intensity is assigned a system default value, but can be altered locally on each individual panel to address varying lighting environments. The LCD switches work in conjunction with the full color touchscreen display to provide a powerful, intuitive user interface. Any function available on the touchscreen display can also be assigned to any LCD key switch on any page. Page selection keys can be assigned to allow the user to jump directly from the displayed page to a new page in a single keystroke. Page names are user programmable and can be configured in a hierarchical arrangement to allow the user to “drill down” to the level of detail desired.
