DESCRIPTION

The are several areas on this test bench:

• lamp outputs
• coil outputs
• sound outputs and audio amplifier
• knocker output
• 12V/5V power supply

Each lamp or coil output drive a LED. Along with the +5V indicator LED, it gives a total of 44 LEDs! 10mm LEDs for coils, 5mm for all the others.

Each LED is identified on the PCB, and labeled according to its function (lamps, coils, sound).

Specific power resistors on SOL6 SOL7 SOL8 and OUTHOLE coil outputs draw a stronger current (0.4A) than a LED to get closer to the real driving condition of a coil (5A or more). As a matter of fact, a bad transistor may seem to work under a low current (LED) but not under a high current (real coil).

The 3 sound outputs (10 points, 100 points, 1000 points) activate 3 LEDs and 3 oscillators to recreate the basic sound board used on pinballs from Cleopatra to Pinball Pool.

The knocker output activates a buzzer.

The power supply is taken from the pinball 12V, with a diode in series to prevent polarity mistakes. The +5VDC needed by the audio stage is generated via a classic 5V regulator, with a "Power +5V" indicator LED.

Compatible with all the driver boards (original Gottlieb®, Boston Pinball, Ni-Wumpf, Rottendog ...) and all-in-one PI-1/X4.
The PI-1 and PI-1/X4 boards include an additional specific test program for this bench.

INSTALLING AND CONNECTING

The test bench can either be connected on the original driver board or on the PI-1/X4 board. All the connectors are aligned, so gently push to insert:



You can leave all the other connectors (A1J2 A1J3 to the displays and A1J6 A1J7 to the switches).
