Controller Address Setting
The rotary switches set the hardware address, which the
software uses to identify each particular display. Each controller
in a network needs a unique address.
To set the rotary address switches, rotate them until the arrow
points to the desired number. To activate test mode or to change
an address, turn off power to the display and then turn it back
on.
Notes:
 Setting both rotary switches to address 0 will activate
Test Mode. Turn the display's power off and back on to
activate testing.
 After testing, reset the rotary switches to an address
other than 0/0 and repower the controller (the software
will not recognize an address of 0).
