The controller sends data to the modules. Refer to the signal summary in
Section 4.2
and Drawings A-178959, A-178960, and B-177838 for more information and the
position of the controller board.
Figure 36

The rotary switches set the hardware address, which the software uses to identify that
particular display. When replacing a controller board, be sure to set the rotary
switches in the same address configuration as the defective controller. Each
controller in a network needs a unique address.
Note: Setting both rotary switches to address 0 (set the switches to 0 by rotating
them counter clockwise until the arrow points to 0) can activate a test mode. The
display’s power must be turned off, and then turned back on to run the test mode.
Communication to the display is not possible while the display is in test mode using
address 0.
