Harris ADC Device Server User’s Guide
4 Introduction
◆ While a play list is running, each event performs a specific task such as play, record, which
includes threading and switching. After the event airs, the actual start time and duration of
the event are written in the As-Run log (file). This log is typically returned to Traffic where
changes in the original schedule can be compared and billing and recordkeeping updated.
System Components
The basic automation system is comprised of the following components:
◆ ADC Device Server
◆ Backup (Redundant) Server (suggested)
◆ Air Client Workstation(s)
◆ Media Client Workstation
◆ File Server
ADC Device Server
The ADC Device Server is the computer dedicated to communicating and controlling the
broadcast devices and client workstations. The device server is the subject of this manual. The
device server controls devices via an RS-422 connection. It also sends and receives frame-
accurate information across the Local Area Network (LAN) from remote client workstations.
Backup (Redundant) Server
(Optional) Backup is an important part of automation. The ability to recover immediately
from hardware failure in a broadcast environment is crucial. Protection against device server
failure can be achieved through a backup (redundant) device server.
The backup device server is a computer which is identical to the main device server. If the
main device server fails, the backup device server takes over the tasks handled by the main
device server. The backup device server is configured the same way as the main device server.
If the main device server fails, the device connections can be manually transferred to the
backup device server. The transfer is accomplished by an RS-422 switching device.
Air Client Workstations
The Air Client workstations are PC computers that run client application software. The
workstations communicate with the Device Server through a local area network.
