7.1 Display Overview
Team Name Message Centers (TNMCs) are programmable LED displays that allow users to
show custom Home and Guest names or messages of ~15 characters on the scoreboard in
place of static vinyl captions. TNMCs are typically ordered factory-installed, but they may
also be field-mounted after the scoreboard is in place. Characters are shown on one line using
single- or double-stroke fonts.
Primary matrix size is 8x48 with 0.75" pixel spacing.
Figure 14 shows an example of TNMCs.
