6.1 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. TNMCs are available with three
different pixel dimensions: 8x32, 8x48, and 8x64. Characters are shown on one line using
single- or double-stroke fonts up to 10" high (254 mm) and 14" (355 mm) for 34 mm and
46 mm TNMC units, respectively.
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.
Both TNMCs and electronic captions are available with amber, red, or white LEDs.
