(4) D/C Power Supply LEDs (D8, D9,D43,D44, D47, D52, D53, D83,D84) - These LEDs light to
indicate the 24VDC received from the Power Supply is functioning and the corresponding fuse
used to protect the external components has not blown.
(5) Power In (J5) - Connector for the 24VDC voltages originating at the Power Supply.
(6) 3.3VDC Power LED (D66) - This LED lights to indicate the 3.3VDC used to power the
circuits on the CPU PCB is operating properly.
(7) 5VDC Power LED (D93) - This LED lights to indicate the 3.3VDC used to power the circuits
on the CPU PCB is operating properly.
(8) LCD Power (J14) - Connection for the 24VDC used to power the LCD touchscreen.
(9) LCD Display (J11) - Connection for the data to the LCD touchscreen.
(10) Heartbeat LED (D87) - This LED blinks when the microprocessor on the CPU PCB is
operating properly.
(11) Communication LEDs (D88 - D91) - These LEDs lights to show the status of the scorer
communication circuits.
Transmit LED (D88) - This LED flashes when the CPU is transmitting data to the scoring
system.
Receive LED (D89) - This LED flashes when the CPU is receiving data to the scoring
system.
Power LED (D90) - This LED lights to indicate the communication circuits have power.
Direction LED (D91) - This LED indicates the direction of the communication between
the pinsetter and the scoring system. The LED lights when the CPU is transmitting data to
the scoring system.
(12) Communication Jumper (JP3) - Jumper used to terminate the communication signal when it
does not continue to additional devices. Do not install jumper.
(13) Boot Jumper (JP4) - Factory use Only.
(14) PMI Solenoid, Ball Lift Output (J3, J4) - Connections to the I/O PCB for the signals used to
energize the solenoids in the String PMIs and control the relay for the ball lift motor.
(15) Masking Unit, Trouble Light Output (J6, J7) - Connections to the I/O PCB for the signals
used to control the 1/2 ball lights on the masking unit and the trouble lights.
(16) Signal Input (J10, J3) - Connections to the I/O PCB for the inputs from the switches on the
pinsetter, the ball accelerator overload, and the ball detect and foul signals.
