Op pin 9 zou 230v moeten binnenkomen ?
Maar op welke meet ik dan 230v 9 en ? ( ik denk dat dit dus 110v moet zijn ?)
Na wat lees en google werk morgen nog eens meten
CN1 pin 1: 18 volts from bridge BR1. This goes directly to power supply connector CN4 pins 5,6,7,8 for the lamp matrix. On games Checkpoint to Guns N Roses, this also supplies voltage to the power supply's voltage regulator VR1 which creates +12 volts for the DMD, going to CN5 pin 5 (for games with 128x16 and 128x32 dot matrix displays only).
CN1 pin 2: 32 volts from bridge BR2 for the solenoids.
CN1 pin 3: 32 volts from bridge BR2 for the solenoids.
CN1 pin 4: High voltage for the displays (games with alpha-numeric and 128x32 displays only).
CN1 pin 5: Not used.
CN1 pin 6: Goes directly to power supply connector CN3 pins 1,2.
CN1 pin 7: High voltage for dot matrix display (unused on pre-dot matrix display games).
CN1 pin 8: Not used.
CN1 pin 9: High voltage for dot matrix display (ground on pre-dot matrix display games.
CN1 pin 10: 9 volts AC to power supply bridge DB1 for generating +5 volts logic. It is also used to generate the +12/-12 volts for the sound board, by doubling up with pin 11's 9 volts (to get 18 volts).
CN1 pin 11: 9 volts AC to power supply bridge DB1 for generating +5 volts logic. It is also used to generate the +12/-12 volts for the sound board, by doubling up with pin 10's 9 volts (to get 18 volts).
CN1 pin 12: Ground for pins 10,11.
