Controller Address Setting
The rotary switches set the hardware address which the software uses to identify that
particular display (Figure 25). Each controller in a network needs a unique address.
Set the switches by rotating them counter-clockwise until the arrow points to the
desired number. The display’s power must be turned off and then turned back on to
activate the test mode or to change the address.
Figure 25: Rotary Switches
Note: Setting both rotary switches to address 0 will activate a
Test Mode. Turn the display’s power off and back on to
activate testing. Then change the address to a number other
than 0/0. The software cannot communicate with a controller
set to address 0.
