1.4 Product Overview
DataMaster Petroleum Price displays are part of a family of Daktronics products
designed for easy installation, readability, and reliability. Microprocessor control
assures consistent operation and accuracy. The DF-4000 Series model Petroleum
Price display is illustrated in Figure 3 below.
The DataMaster Series includes:
Petroleum Price Displays: Standard petroleum price displays in the US
employ a 9/10 fraction. International models (DF-4000 series) typically
have four full digits and a decimal.
The Petroleum Price displays are available in two styles, a full-cabinet model
designed for standalone use (DF-4100), and a front-insertion, or “drop-in”, model
designed for installation in an existing or custom sign (DF-4000).
DataMaster displays use light emitting diodes to illuminate their numeric digits.
(Light emitting diodes, or LEDs, are tiny, solid-state components that use a
semiconductor to transform electrical current into light; they are high-intensity, low-
energy lighting units.)
The displays feature highly visible PanaView

digits 10", 13", and 18" tall. (The
front-insertion Petroleum Price model is available with 10", 13", and 18" digits.) All
DataMaster displays are configured with red or amber LEDs.
Because of their LED technology, the displays consume little power, some barely
more than a household lamp. Power usage for individual displays in this series is a
maximum 150 W. All models have an option of 120 V or 240 V.
DataMaster cabinets, specially developed for outdoor use, are constructed of heavy-
gauge aluminum. Digit faceplates are black, and they are set directly into the surface
of the display. Mounting weights and dimensions for each model are listed in
Section 2 of this manual.
