1.2 Network Concepts
The concept of using LED displays as a cost effective, high impact method of
communication is rapidly growing throughout many industries and businesses. The
reasons for this growth are many, but the need for additional features and the
complexity of multiple display installations has emerged. Daktronics display systems
have been designed to meet those needs.
The common thread to most client requests is a means of programming and
controlling a group of displays from a central control point. Daktronics responded by
developing a powerful system of interconnecting and controlling displays. Great care
has been taken to design products that will satisfy a wide variety of installations.
Some of the design goals of these systems include the following:
•
Easy transfer of messages
•
The ability to tell a display or group of displays in the network which
message should run
•
The ability to determine the status of any display on the network
•
The ability to control multiple display technologies on the same network

displays are designed and manufactured for
performance, reliability, easy maintenance, and long life. A light sensor on the front
of the primary display is used for automatic dimming of the LEDs based on the
ambient light levels.
The Daktronics AF-3300 display contains two separate LED matrices. The pixels
have either a 12 mm or a 20 mm center-to-center spacing, and are lit using LEDs
(light emitting diodes). Although the matrices are different sizes and have different
color capacities, a single controller provides signal to the display.
