9.1 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 16, 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 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.
