If this display is selected (factory default), it allows
the Allegiant system to dynamically inform the user
of the system status. The 12 column display is
divided into smaller message columns (see figure

whether the switcher is running or stopped, the
switcher's direction, whether a monitor or remote
camera is locked, and the alarm status of the camera
