Daktronics AF-3065-34-RGB - Manual (Page 11)

Power Supply: converts AC line voltage from the load center to low DC voltage for one or more
module driver boards.
RS232: RS232 is a standard PC communication type with a maximum cable length of 25 feet (7.62
meters).
RS422: RS422 is a standard differential communication type with a maximum cable length of 4000
feet (1.2 kilometers).
Display Address: The display address is an identification number
assigned to each display of a network. It is set by flipping DIP switches
on the controller. The control software uses the address to locate and
communicate with each display. Displays that are on the same network
cannot have the same address.
Introduction 1-5
Signal Converter: The signal converter, shown in Figure 3, is a
Daktronics supplied unit that converts the data from RS232 to RS422,
or RS232 to fiber optic signal. The signal converter is connected to the
control PC via straight through serial cable.
Refer to Figure 3 and Figure 4 while reading the following component
descriptions.
Driver/Pixel Board: The LED pixels are mounted directly onto the
driver/pixel board. This board is also responsible for the switching and intensity levels of the LEDs.

(RS232 to RS422 Shown)
LED (light emitting diode): low energy, high intensity lighting units.
Louver: a black plastic shade positioned horizontally above each pixel row. The louvers increase the
level of contrast on the display face and direct LED light.
Module: 34mm Galaxy modules are 8 pixels high by 8 pixels wide. Each is individually removable
from the front of the display.
