Page: 11 / 36

OPERATION
The following information is for general use of the AD2078
keyboard. For use with a specific switching system, refer
to that system's Operating Instructions manual.
Keyboard control of switching system functions is, generally,
"monitor oriented". A keyboard controls functions associated
with the the monitor to which it is "called". System monitors
which are not under keyboard control continue to operate
under control of the switching system, independent of
keyboard actions.
See Figure 3, page 4, for the location and arrangement of the
keyboard displays and controls described in the following
sections.
A built-in test capability is provided in the AD2078 keyboard
to assist in determining faults in the software or hardware of
the keyboard. See the Appendix, page A-2, for the built-in test
operating procedures.
Displays
Four LED displays are provided on the keyboard.
1. STATUS - This LED display shows the current status of the
connected switching system. Refer to the system's
Operating Instructions manual for STATUS display details.
The STATUS display is three digits.
2. MONITOR - This display shows the number of the monitor
which the keyboard is currently controlling (the "called"
monitor). The MONITOR display is five digits.
3. CAMERA - This display shows the number of the camera
(video input) currently being displayed on the called
monitor. The CAMERA display is six digits.
4. ENTER - This display shows the numbers entered on the
numeric keypad by an operator in preparation for requesting
some action. The ENTER display is four digits.
Whenever a number appears in the ENTER display it
indicates that some action has been initiated but not
completed. This action should be completed or the entry
cleared by pressing the CLEAR button before initiating any
new action.
