The controller sends data to the modules. Refer to the signal summary in Section 4.2
for more information and to the component location drawings for the position of the
controller board.
Figure 35 and Drawing B-177838 illustrates a typical controller.

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.
