IMPORTANT NOTES:
1. Always disconnect scoreboard power before doing any repair/maintenance work on the
message centers.
2. Permit only qualified service personnel to access internal display electronics.
3. Disconnect power when not using the scoreboard.
3.1 Display Overview
Team Name Message Centers (TNMCs) are programmable LED displays that allow users to
show custom Home and Guest names or messages of about 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 in three different
pixel arrangements: 8x32, 8x48, and 16x80 (34 mm only). Characters are shown on one line
using single- or double-stroke fonts 10" (254 mm) and 14" (355 mm) high for 34 mm and 46
mm TNMC units, respectively. The 16x80-34mm units display 20" (508 mm) high 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.
Both TNMCs and electronic captions are available with amber, red, or white LEDs.
