Daktronics BA-1518-11 Multi-Section Outdoor LED Scoreboard - Manual (Page 52)

TNMC Controller
The controller, located on the rear-access panel, receives signal from the CLI and sends data to
the modules. Refer to Drawing A-145045 for the position of the controller board. Figure 7,
below, illustrates a typical controller.
Figure 7: Controller Component Layout
DIP switches are located on the controller's MDC (see Figure 7). These DIP switches set the
hardware address that the software uses to identify that particular display. When replacing a
controller board, be sure to set the DIP switches in the same address configuration as the defective
controller.
>>Note: Setting the DIP switches to address 0 (turn all the switches to OFF by switching them
toward the printed switch numbers) can activate a test mode. Power down the display and then
reconnect to run the test mode.
