9.3 Signal Summary
Reference Drawing:
Control Layout; Outdoor LED TNMC................................................... Drawing B-107507
Refer to Drawing B-107507 for complete information on TNMC signal routing. From signal input
from the All Sport controller, routing can be summarized as follows:
1. Data from the display controller travels via cable harness into the display.
2. The signal then travels through the power and signal entrance enclosure, (power and
signal termination panel) to the J1 connector on the current loop interface card.
3. Data exits at J3 and is relayed to the J1 connector on the multipurpose display controller
(MDC). The signal then exits the MDC and enters the first module of the TNMC.
4. Signal is relayed from module to module until it reaches the last module on the message
center. Refer to Drawing B-107507.
9.4 Power Summary
