Operator`s manual
Using a Keyboard Controller 2-3
Keyswitch Positions
The AD2078A keyboard controller allows complex video switching operations to be accomplished with a
set of relatively simple key commands. System operators will perform many of these operations in the
normal course of their shifts, depending on their scope of system access as defined by the system
administrator.
The AD2078A’s keyswitch enables three operating positions, “OFF”, “PROG”, and “DISP”. The key can
be removed only when turned to the “OFF” position. With the key removed, operators can perform the
following functions without changing system parameters originally set up by the administrator or system
installer.
• log on and off to the AD168 system.
• call a monitor.
• call a camera to the monitor under keyboard control
• control of pan, tilt, zoom, focus, and iris adjustments
• call presets
• activate auxiliaries
• operate and control tours
• call salvos
• acknowledge alarms
The remainder of this chapter will discuss fundamental keyboard operations.
This manual covers only those keyboard functions which are performed with the keyswitch in the “OFF”
position. If authorized by a system administrator, an operator can perform certain keyboard setup and
system programming functions. For information about keyboard operation beyond the scope of this
manual, please consult your system administrator.
