About the AD168 Video Switching System 1-3
• The AD Touch Tracker is another keyboard which can control system functions. It duplicates the
functionality of the AD2078A but has a different key layout and design. Instructions in this document
will refer to the 2078A. For information about the Touch Tracker refer to the AD Touch Tracker
Manual, document number 8000-1657-02.
Equipment That Controls AD168
The equipment that enables you to perform complex video switching functions with simple key
commands is the AD168 switching bay. The bay contains central processing and power supply circuits,
and modules that connect to the system cameras and monitors. An optional bay module is available
which connects directly to domes and pan/tilt cameras without the need for interface devices. The bay is
mounted on a rack at a centrally convenient location, and connects to all system keyboards. Connections
to, and servicing for the bay should only be performed by qualified technical personnel.
For full-scale operations, bay programming is initially set up and edited by the system administrator using
a PC and software provided by American Dynamics. Small scale operations can be programmed by the
administrator or an authorized operator directly from an AD2078A or Touch Tracker. System keyboard
programming is performed in concert with a program monitor connected to the switching bay.
The bay is connected to a system printer which automatically outputs hard copy system status
messages. Printer documentation provides an important record of system events in the order in which
they happen.
Peripheral Equipment
Other devices that may be connected to the switching bay include the following:
• Alarm interface units
• Auxiliary interface units
• Code distribution, conversion, and translation devices used for the control of pan/tilt cameras and
programmable domes.
• Port expanders which enable the connection of additional system keyboards.
• Receiver / Drivers used for the control of pan/tilt cameras
Depending on the requirements of your facility, additional special input devices may be required. Motion
detectors, twilight sensors, and smoke detectors provide a few examples of such devices.
