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.
Electronic captions, on the other hand, are pre-programmed to only show specific labels to
match the captions for a particular sport mode, making it much simpler to switch between
sports. Characters are shown on one line using single-stroke fonts.
Primary matrix size is 8x48 with 0.75" pixel spacing. Figure 20 shows examples of both
TNMCs and electronic captions.
