6.1 Team Name Message Center System Overview
Team name message centers (TNMCs) are available in two sizes: an 8x32 matrix
model with four 8x8-pixel modules, and an 8x48 model comprised of six 8x8
modules.
Figure 11 , below, illustrates the larger unit. Light emitting diodes (LEDs)
– tiny, solid-state lighting units – illuminate the displays.
The message centers feature an array of red or amber LEDs, and they are capable of
displaying characters up to 10" high. Pixels in the red TNMC consist of a three-LED
cluster, while amber TNMCs use four-LEDs per pixel.
The four-module TNMC measures approximately 1'-4" tall by 4' wide, while the six-
module TNMC measures approximately 1'-4" by 6' wide; both have an in-cabinet
depth of about 5". The smaller units weigh about 80 pounds per pair, and the larger
TNMC sets add about 120 pounds to scoreboard weight.
TNMCs are typically installed in pairs. Although the message centers customarily
are used for team names (home and guest), they are programmable and can display
any type of caption. Characters are shown on a single line, and either single- or
double-stroke fonts may be used for the caption or name.
