Display Overview
Team Name Message Centers (TNMCs) are programmable LED displays that can show
custom Home and Guest names or messages of about 15 characters in place of static
vinyl captions. TNMCs are typically factory-installed, but they can also be added later,
after the scoreboard has been mounted. Characters are shown on one line using single-
or double-stroke fonts 6" (152 mm) or 8" (203 mm) high.
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.
TNMCs and electronic captions (
Figure 16 ) are both available with red, amber, or white
LEDs. Refer to the table below for additional message center specifications.

Initialization Information at Startup
Each time the display is powered up and there is no All Sport signal present, the display
runs through an initialization process during which it tests all LEDs and addresses. The
message center first displays the proper address number.
If the entire display fails at startup, power may not be properly connected or the address
setting may not be correct on the display driver. Check both in the event of a failure.
