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 activate the test mode.
