INSTALLATION:
INSTALLATION TIME: About 15 minutes
TOOLS REQUIRED: 1/4” Nutdriver

1. Unplug the AC power from your pinball machine. Remove game backglass. Unscrew and remove all original glass displays, master driver board and all inter-board connecting cables.

2. Mount all new boards in their respective locations. You may slide the LED display boards horizontally to adjust their positions for alignment with your backglass windows. If not already mounted, place the foam light shields on their respective LED display boards.

3. Connect the cables. Observe correct polarity on all ribbon cables - the red striped wires on all ribbon cables go to PIN #1 (also labeled RED) on all boards.

4. Observe the position of the small jumper block on the 2 pin connector near the board center labeled LEFT or RIGHT . This indicates the side of the game on which the board is mounted.

5. Double-check all connections, plug in the machine, and turn the game on. The LED’s will light up. Pressing the DIAGNOSTIC pushbutton on the Master Driver board will illuminate all segments of all displays. This indicates that all boards and cables in the PINSCORE System are operating correctly. Use the thumbwheel BRIGHTNESS control on the Master Driver & Display board to set your preferred illumination level.
