Maintenance and Troubleshooting

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.
Complete the following steps to remove the controller from the display:
Tools required:
1
/
8
" hex wrench and
3
/
16
" nut driver
1. Remove the module directly in front of the controller
2. Disconnect power from J5
3. Remove all power and signal connections from the board (pushing apart the
latches and carefully pulling them from the jack will release the “Locked”
connectors) – when replacing the board, it is helpful to have the cables
labeled as to which was removed from which connector.
4. The board is held in place using six screws. Remove the screws using a
3/16" nut driver
Follow the previous steps in reverse order to install a new controller board.
