Keyboard Displays
Monitor Display
The monitor display is a three-digit seven-segment
display that serves two purposes. One purpose is to
display the number of the monitor that the keyboard
is currently controlling. This monitor's camera
number appears in the camera display, and the pan
and tilt keys control camera movement if applicable.
The second purpose is to provide a prompt to a user
to log-on to the system if the log-on feature was
enabled by the system installer. Once the user has
logged on, the display reverts to the monitor number.
Camera Display
The camera display is a four-digit seven-segment
display. It shows the number of the camera being
viewed on the monitor that the keyboard is
controlling. However, there are three modes for this
display. The camera mode is the default, but when
the user pushes one of the numeric data keys, this
display
shows the numeric keystrokes as they are entered
from the keyboard and also causes the DATA box
above the camera display to light. If the keyboard
remains inactive for about five seconds, the camera
display will return to default mode and again display
the camera number. The third mode is for error
display (reference the Error Messages section of this
manual). When the user enters an erroneous key
sequence, the keyboard beeps and an error number
is temporarily displayed (approx. 2 seconds). If an
operator attempts to invoke a restricted function, the
camera number will be temporarily replaced with an
appropriate system error number. If an attempt is
made to access a monitor or remote device which
has been locked by a higher priority User, the
camera number will be temporarily replaced with an
appropriate error number, then the user number of
the operator who placed the lock will be briefly
displayed.
