Controller Address Setting
The rotary switches set the hardware address of the controller. Each Primary
display in a network needs a unique address, as shown in
Figure 17. Each
controller in a network also needs a unique address.
Set the switches by rotating them counterclockwise until the arrow points to
the desired number. The display’s power must be turned off and then turned
back on to activate a change in the address.
Note: Setting both rotary switches to address 0 will activate a Test Mode.

off the hooks.
