Daktronics DF-4000 - Manual (Page 11)

Introduction 1-5
The DataMaster outdoor LED displays have been designed for use with a
DataMaster
™
100 hand-held controller. Also available is a radio controlled RC-100
system, or the RC-50 mini remote control. All controller devices use a keyboard
overlay (called an insert) for display control.
1.5 Model Names
Daktronics displays, video screens, and scoreboards are differentiated by their model
numbers. The displays described in this manual all carry the two-letter prefix, DF-,
which indicates that they are DataMaster models. The letter D indicates that they are
numeric displays; the letter F indicates outdoor LED technology.
In the outdoor LED display series, typically the first set of numbers following the
prefix identifies the series or product line, while the second set of numbers refers to
digit height. A final letter denotes digit color. With Model DF-4000-13-A, for
example, 4000 identifies the Petroleum Price full-cabinet line, and 13 signifies that
the display’s primary digits are a nominal 13" tall. In the example, the letter A
signifies that the digits are amber, while R would indicate red, and G green LED
digits.
1.6 Product Safety Approval
Daktronics outdoor displays are ETL and UL listed and tested to CSA standards for
outdoor use. Contact Daktronics with any questions regarding the testing procedures.
