KEYBOARD CONTROL
The following instructions are for verifying basic operation of
the system. For complete setup and programming of the
AD1650B, refer to the AD1650B System Programming
Manual, OP1650BSPB.
All system setup and control functions are accessible through
keyboards connected to the system. As a security feature,
AD2078 keyboards have a keyswitch for restricting the setup
programming functions. Refer to the keyboard installation and
operation manual for these restrictions.
The following operations are available for system test or
operation prior to system setup or programming:
• Calling a monitor to a keyboard
• Calling a camera to a monitor
• Controlling the pan/tilt, lens, and auxiliaries at a camera site
equipped with a Receiver
Video Selection
Video control functions are accessed from a keyboard by first
placing one of the monitors of the system under the control of
