Microprocessor control assures consistent operationand accuracy.Featuring large, highly visible digits, the boards use light emitting diodes to illuminate the display. (AnLED is a tiny, solid-state device made of a semiconductor material that transforms electrical currentinto light.) Scoreboards in this series typically use red-orange LEDs for best outdoor display. Becauseof their LED technology, the scoreboards consume little power – barely more than a single householdlamp. (Maximum power usage for the largest scoreboard in this series is 560 watts.)Cabinets for the displays are of heavy-gauge aluminum construction. Mounting weights and dimensionsfor each model are listed in Section 3 of this manual.1.4 Model IdentificationDaktronics scoreboards are differentiated by their model numbers: BA-1518, for example, designates aspecific baseball scoreboard. The two-letter prefixes for scoreboards in this manual include thefollowing: BA – baseball; FB – football; MS – multi-sport; and SO – soccer.In the outdoor LED scoreboard series, the first number or first two numbers following the prefix simplyidentify the scoreboard line, while the second set of numbers often refers to digit size. With the BA-1518 scoreboard, "15" identifies the product line, and "18" signifies that the board's primary digits are anominal 18" tall. Not all scoreboard lines follow this identification feature, however, and the three orfour numbers following the prefix may simply identify the specific model.Most Daktronics scoreboards also carry a two-number suffix that refers to indoor-outdoor status andpower supply: –9 and -10 are indoor displays, 120 V and 230 V respectively; and -11 and -12 areoutdoor scoreboards, 120 V and 230 V. All of the LED scoreboards in this manual carry the -11 suffix,signifying that they have been designed and manufactured for outdoor use and have a 120 V AC powerrequirement.1-2 Introduction
